Evaluation and design of a small portable EMG amplifier with potential RMS output. (1/93)

The present study attempted to design and evaluate a small portable electromyogram (EMG) amplifier that can output enhanced EMG and its root mean square (RMS) value. The production and design were of a laboratory scale without any special or high cost circuit construction. The designed amplifier was actually innovated according to the actual working conditions based on physiological anthropology. The present amplifier was compared with commercially available products and proved to be of practical use. The device was installed with a sufficiently small body depicting 8-channel variable gain AC amplifier and variable time-window RMS-to-DC converter. The prototype was battery-driven and well-shielded to minimize external noise interference.  (+info)

Versatile, high-speed force transducer using a laser diode beam as an optical lever. (2/93)

A force transducer with variable sensitivity and speed is described. Its moving element is a cantilever beam that projects vertically into a muscle bath. A brace constrains bending of the beam to a short, proximal "hinge." Rotation of the beam about the hinge is amplified 30-fold by an optical lever consisting of a laser diode beam reflected from a mirror on the cantilever to a photodiode pair. This design places the electrical components at a distance from the damp environment of the muscle bath. Large changes in sensitivity and speed can be obtained by substituting different cantilevers. Smaller changes can be made by varying the length of the hinge. A transducer with a 6-mm cantilever optimized for the study of single, skinned skeletal muscle fibers is described in detail. This device had a resonant frequency of 22 kHz and sensitivity such that the total root-mean-square noise in the circuit was more than 500-fold smaller than the expected maximum force. Variations of this device with orders of magnitude different sensitivities are also described.  (+info)

The impact of hearing on communication. (3/93)

The study was designed to assess the impact of hearing impairment on communication between older hospital patients and medical staff and to see whether intervention to improve hearing influences perceived communication. Structured interviews were held with 200 mentally alert elderly hospital in-patients before and after the introduction of voice amplifiers and acetate cards depicting a hearing problem. Prior to intervention 22% of patients rated communication with their doctor as poor or unsatisfactory. Following intervention there was a significant improvement (Chi-square p=0.006), with only 6% of patients reporting communication with their doctor as poor or unsatisfactory. Most of the patients who felt communication was unsatisfactory could not hear what was being said. We conclude that simple measures can improve the number of older patients hearing what their doctor says and improve their perception of communication with the hospital doctor.  (+info)

Detection of ventricular fibrillation in implantable defibrillators with automatic gain control amplifiers: effects of programming sensitivity. (4/93)

AIMS: In newer implantable cardioverter-defibrillators with automatic gain control amplifiers the maximum possible sensitivity is programmed with the aim of securing optimal detection of ventricular fibrillation. This study was designed to prove that a reduction in maximum sensitivity is safe with respect to appropriate sensing of ventricular fibrillation, while avoiding sensing of extracardiac signals. METHODS AND RESULTS: Forty-two consecutive patients, undergoing defibrillator implantation/replacement with programmable maximum auto-gain sensing sensitivity (Ventak Mini III, Ventak AV , Guidant, St. Paul, MN, U.S.A.), were prospectively investigated. Thirty-four patients were implanted with a dual-coil lead system, providing integrated bipolar sensing (Endotak, Guidant, St. Paul, MN, U.S.A.), eight patients received a single-coil lead system with true bipolar sensing (Sprint, Medtronic, Minneapolis, MN, U.S.A.). During device implantation and pre-discharge testing, arrhythmia detection times of induced ventricular fibrillation were compared at programmed maximum (0.18 mV) and minimum (0.43 mV) sensitivity in a randomized manner. Seventy-six induced episodes of ventricular fibrillation were analysed. The mean arrhythmia detection times did not differ between the programmed sensing levels (maximum sensitivity: 1612 +/- 307 ms, vs minimal sensitivity: 1,602 +/- 330 ms; P = ns). The results were not affected by the type of implanted lead system (integrated bipolar versus true bipolar sensing). CONCLUSION: In the implantable defibrillator devices, reduction in maximum sensitivity did not impair the detection of induced episodes of ventricular fibrillation.  (+info)

Sensitive calibration and measurement procedures based on the amplification principle in motion perception. (5/93)

We compare two types of sampled motion stimuli: ordinary periodic displays with modulation amplitude m(o=e) that translate 90 degrees between successive frames and amplifier sandwich displays. In sandwich displays, even-numbered frames are of one type, odd-numbered frames are of the same or different type, and (1) both types have the same period, (2) translate in a consistent direction 90 degrees between frames, and (3) even frames have modulation amplitude m(e), odd frames have modulation amplitude m(o). In both first-order motion (van Santen, J.P.H. & Sperling, G. (1984). Temporal covariance model of human motion perception. Journal of the Optical Society of America A, 1, 451-73) and second-order motion (Werkhoven, P., Sperling, G., & Chubb, C. (1993). Motion perception between dissimilar gratings: a single channel theory. Vision Research, 33, 463-85) the motion strength of amplifier sandwich displays is proportional to the product m(o)m(e) for a wide range of m(e). By setting m(e) to a large value, an amplifier sandwich stimulus with a very small value of m(o) can still produce visible motion. The amplification factor is the ratio of two threshold modulation amplitudes: ordinary circumflexm(o=e) over amplified circumflexm(o), circumflexm(o=e)/circumflexm(o). We find amplification factors of up to about 8x. Light adaptation and contrast gain control in early visual processing distort the representations of visual stimuli so that inputs to subsequent perceptual processes contain undesired distortion products or 'impurities'. Motion amplification is used to measure and thence to reduce these unwanted components in a stimulus to a small fraction of their threshold. Such stimuli are certifiably pure in the sense that the residual impurity is less than a specified value. Six applications are considered: (1) removing (first-order) luminance contamination from moving (second-order) texture gratings; (2) removing luminance contamination from moving chromatic gratings to produce pure isoluminant gratings; (3) removing distortion products in luminance-modulated (first-order) gratings - by iterative application, all significant distortion products can be removed; (4) removing second-order texture contamination from third-order motion displays; (5) removing feature bias from third-order motion displays; (6) and the same general principles are applied to texture-slant discrimination in which x,y spatial coordinates replace the x,t motion coordinates. In all applicable domains, the amplification principle provides a powerful assay method for the precise measurement of very weak stimuli, and thereby a means of producing visual displays of certifiable purity.  (+info)

Improving the classroom listening skills of children with Down syndrome by using sound-field amplification. (6/93)

Many children with Down syndrome have fluctuating conductive hearing losses further reducing their speech, language and academic development. It is within the school environment where access to auditory information is crucial that many children with Down syndrome are especially disadvantaged. Conductive hearing impairment which is often fluctuating and undetected reduces the child's ability to extract the important information from the auditory signal. Unfortunately, the design and acoustics of the classroom leads to problems in extracting the speech signal through reduced speech intensity due to the increased distance of the student from the teacher in addition to masking from excessive background noise. One potential solution is the use of sound-field amplification which provides a uniform amplification to the teacher's voice through the use of a microphone and loudspeakers. This investigation examined the efficacy of sound-field amplification for 4 children with Down syndrome. Measures of speech perception were taken with and without the sound-field system and found that the children perceived significantly more speech in all conditions where the sound-field system was used (p < .0001). Importantly, listening performance with the sound-field system was not affected by reducing the signal-to-noise ratio through increasing the level of background noise. In summary, sound-field amplification provides improved access to the speech signal for children with Down syndrome and as a consequence leads to improved classroom success.  (+info)

Electrical engineering and nontechnical design variables of multiple inductive loop systems for auditoriums. (7/93)

This research analyzed both engineering and nontechnical issues involved in the use of Induction Loop Amplification (ILA) devices in auditoriums or large gathering places for hard-of-hearing individuals. A variety of parameters need to be taken into account to determine an optimal shape/configuration for the ILA device. In many cases, an optimal configuration is different from those proposed for classroom use (Ross, 1969; Hodgson, 1986; Clevenger, 1992). Experimental results were obtained for a double-loop configuration in such a setting (a university gymnasium/auditorium in this case). The results demonstrate that a double-loop configuration is a viable possibility for auditorium use. Several variables using this configuration were examined, and experimentation was done. Various implications, including consequent nontechnical issues specific to this application, are discussed as well. Technical and nontechnical aspects of the ILA configuration need to be examined together when designing an optimal system.  (+info)

The cochlear amplifier: augmentation of the traveling wave within the inner ear. (8/93)

PURPOSE OF REVIEW: There have been many recent advancements in our understanding of cochlear function within the past ten years. In particular, several mechanisms that underlie the sensitivity and sharpness of mammalian tuning have been discovered. This review focuses on these issues. RECENT FINDINGS: The cochlear amplifier is essentially a positive feedback loop within the cochlea that amplifies the traveling wave. Thus, vibrations within the organ of Corti are sensed and then force is generated in synchrony to increase the vibrations. Mechanisms that generate force within the cochlea include outer hair cell electromotility and stereociliary active bundle movements. These processes can be modulated by the intracellular ionic composition, the lipid constituents of the outer hair cell plasma membrane, and the structure of the outer hair cell cytoskeleton. SUMMARY: A thorough understanding of the cochlear amplifier has tremendous implications to improve human hearing. Sensorineural hearing loss is a common clinical problem and a common site of initial pathology is the outer hair cell. Loss of outer hair cells causes loss of the cochlear amplifier, resulting in progressive sensorineural hearing loss.  (+info)

We report on investigation the potential of a 7 wt% (8.35 × 1020 Tm3+/cm3) doped silicate fibers for high-gain fiber amplifiers. Such a high ion concentration significantly reduces the required fiber length of high-power 2 μm fiber laser systems and allows the high-repetition rate operation in 2 μm mode-locked fiber lasers. To evaluate the feasibility of extracting high gain-per-unit-length from this gain medium, we measure several key material properties of the silicate fiber, including the absorption/emission cross-sections, upper-state lifetime, fiber background loss, and photodarkening resistance. We show through numerical simulations that a signal gain-per-unit-length of 3.78 dB/cm at 1950 nm can be achieved in a watt-level core-pumped Tm3+-doped silicate fiber amplifier. In addition, an 18-dB 2013-nm amplifier is demonstrated in a 50-cm 7 wt% Tm3+-doped double-clad silicate fiber. Finally, we experimentally confirm that the reported silicate host exhibits no observable photodarkening.

The wide bandwidth in the unlicensed 60 GHz band enable short range wireless data transfer in the order of tens of gigabit per second. This, combined with the relatively low-cost, very high performance SiGe fabrication processes, has led to a feasibility study of a 60 GHz transceiver at Heidelberg University.

The performance of analog photonic links employing highly compressed erbium-doped fiber amplifiers - Semantic ScholarThe performance of analog photonic links employing highly compressed erbium-doped fiber amplifiers - Semantic Scholar
We present the tradeoffs of employing highly compressed erbium-doped fiber amplifiers (EDFAs) in analog microwave photonic links. We employ the newly developed concept of noise penalty and introduce the concept of generalized relative intensity noise to facilitate system design. Theoretical and experimental results demonstrate that a highly compressed EDFA: 1) can achieve near shot-noise-limited performance, even with large optical noise figure and 2) can simultaneously increase the spurious-free dynamic range, increase the compression dynamic range, increase the analog gain, and decrease the analog noise figure, as compared to an unamplified link with identical components.

SBIR Phase II: Low-Cost, High-Efficiency Power Amplifiers for Magnetic-Resonance Imaging | SBIR.govSBIR Phase II: Low-Cost, High-Efficiency Power Amplifiers for Magnetic-Resonance Imaging | SBIR.gov
This Small Business Innovation Research Phase II will develop and test a prototype low-cost, high-efficiency transmitter for magnetic-resonance-imaging (MRI) systems. Existing MRI transmitters use conventional power amplifiers (PAs), which makes them inefficient and consequently large, heavy, and expensive. Phase I has demonstrated the feasibility of using developed high-efficiency amplification techniques to produce significantly more power from a given transistor, thus lowering the cost. Also demonstrated was the feasibility of using these amplifiers to produce the pulsed-RF signals used by MRI. Phase II will develop a prototype transmitter that combines high-efficiency power amplification with digital signal processing to provide both low cost and superior signal quality. This in turn will produce superior image quality, resulting in improved diagnostics. The transmitter will be organized into broadband RF-power modules that can be combined in building-block fashion to produce transmitters ...

The ideal amplifier An ideal amplifier will pass the input signal through to the output undistorted but enlarged (gain set by user), with no delay. It will not be affected by the output impedance of the source (sensor). In addition the ideal amplifier will be able to drive any load: supply any current. No real amplifier is ideal, but an op amp can come close, at least with regard to gain at low frequency. The typical IC op amp has an open loop gain of 10^6 and a low frequency input impedance of about 10^12 ohms. Well see shortly how such high open loop gain is harnessed to create user-desired gains.

Buying Guide | VTL Amplifiers, IncBuying Guide | VTL Amplifiers, Inc
Multi-function integrated amplifiers are similar to stereo receivers, in that they are usually specified in systems that have a prerequisite for simplicity and limited space availability. Integrated amplifiers offer the shortest link between music source and output device, with a minimum of interconnect cables and rack space required, and usually offering a headphone output for personal use in smaller living spaces.. The signal path is simple and direct, with a minimum number of gain stages. The signal path is usually source component to power amplifier (which has the volume control), and power amplifier to loudspeakers. This simplicity means not having to be concerned with impedance matching between components, and the sound is therefore purer with less inter-stage buffering involved.. With this minimalist approach the integrated amplifier acts as the primary electrical conduit between your music source, (e.g. CD, tuner, tape, etc.) and your loudspeakers. In such a system just one power switch ...

When I first heard the Eagle 2 at the 1985 Winter CES I knew this amplifier was a winner. I was eager for a chance to get my hands on it, but I also knew that J. Gordon Holt was champing at the bit to do the same. So it came as both a surprise and a delight when ye Gracious Editor gave me first crack at the Eagle 2. I wasnt disappointed; the little Eagle more than lived up to expectations. Its not the best power amplifier Ive ever heard, but its damn good.

Radio frequency amplifier and error rate | Physics Forums - The Fusion of Science and CommunityRadio frequency amplifier and error rate | Physics Forums - The Fusion of Science and Community
Each amplifier adds some noise. The noise contributed by a given amplifier is, of course, amplified by the following amplification stages. So if you have two amplifiers and one adds less noise than the other, then you should place the lower-noise amplifier earlier in the sequence. If you placed the noisier amplifier first, then its noise gets amplified by the following stage, and you end up with more noise. So swapping the order of the amplifiers doesnt change the total gain of the signal, but it certainly changes the total noise. So you can also add a lower-noise amplifier to the front end of an existing device and increase the final SNR for the same reasons ...

Unipolar Variable Gain High Speed Amplifier F70PV - Pendulum InstrumentsUnipolar Variable Gain High Speed Amplifier F70PV - Pendulum Instruments
The Pendulum Instruments Unipolar Variable Gain High Speed Linear Amplifier F70PV is a very fast, unipolar, linear amplifier having a variable amplification of 0-10 times and capable of voltage output of +70V. The amplifier has an attenuator at the input. At the knob position 10 the amplification is equal to 10x. Standard value is 500 ohm, but other values like 50 ohm, 1kohm, etc., can be fitted in on request. Any signal source with amplitude within 0 and +7V can be used as an input device. A typical output voltage range of a function generator will not harm the amplifier but the input protection network will limit the signal amplitude to +7 V (after attenuator) and may cause clipping. The Unipolar Variable Gain High Speed Linear Amplifier F70PV is equipped with a microfuse rated at 15 mA, which will be blown if the input voltage exceeds 300% of the maximum. ...

MODE-LOCKED FIBER LASER BASED ON NARROWBAND OPTICAL SPECTRAL FILTERING AND AMPLIFIER SIMILARITONS - Patent applicationMODE-LOCKED FIBER LASER BASED ON NARROWBAND OPTICAL SPECTRAL FILTERING AND AMPLIFIER SIMILARITONS - Patent application
0073] In addition, an amplifier similariton fiber laser with a dispersion map can be constructed. In such a laser, despite large changes in both the magnitude and sign of the total cavity group-velocity dispersion (GVD), the pulse parameters remain nearly constant. A narrow-band spectral filter facilitates the evolution toward the amplifier similariton solution. Strong nonlinear attraction to this asymptotic solution in the amplifier section of the laser underlies the pulses independence from the global cavity parameters. The freedom from global parameters allows for several scientifically-significant cavity designs which will, in addition, be important for some applications. The dispersion-mapped amplifier similariton (DMAS) laser is a new mode of operation at large anomalous net GVD, which complements the well-known soliton operation. As a practical consideration, the DMAS laser generates shorter pulses with higher energy than soliton operation at large anomalous dispersion. As a consequence, ...

ABSTRACT: High power fiber lasers have made significant progress in last several years. Several kW of output power has been demonstrated, which enables a wide range of new applications from laser welding, laser cutting, and laser drilling to military defense. While high power fiber lasers have been successfully deployed in industry, one piece of critical components, fiber isolator, is still not available. For the moment, free-space isolator has to be used. In this proposal, we propose to develop an all-fiber isolator for 1 micron high power fiber lasers and amplifiers. An all-fiber isolator with multi-hundreds throughput power level will be demonstrated and delivered. Successful development of this proposed high Verdet constant fiber and all-fiber isolator will enable many new applications of high power fiber lasers, and revolutionize high power fiber laser and amplifier developments. BENEFIT: This proposed all-fiber isolator can be used for current DoD high power 1 micron fiber lasers and ...

A powerful integrated with an extensive spec, but will its big sound stage appeal? Narrowly edging out the Musical Fidelity offering, the RA-1592 is both the largest amp here and the biggest in Rotels range. It is only slightly less powerful than the M6si too and quotes 2x 200W into 8ohm power output. This is achieved thanks to the manufacturer using its own toroidal transformers and laying the output stage out as a dual mono design. It is also the only model here to have switchable A and B speaker output terminals. In fact, this is just one part of a very comprehensive special cation. The RA-1592 has three RCA line inputs, a moving-magnet phono stage and separate pre and subwoofer under 200 outputs. These are joined by seven digital inputs three optical.

A system and method for an amplifier control circuit is provided which does not require the use of a large off-chip or on-chip capacitor for achieving a low frequency coupling corner, while still effectively allowing AC coupling the data detection circuit. In addition, the input offset voltage to the amplifier may be compensated and the inherent random low frequency input voltages provided to the amplifier may be controlled or canceled. Further, the amplifier control circuitry includes a freeze capability which allows the control circuitry to halt all updates to the input offset/low frequency control circuit when the voltage input signal is interrupted. In addition low frequency control and offset compensation updates may be performed without causing large output signal glitches so that the integrity of the received signal will not be compromised. In a preferred embodiment the system and method may be utilized for data detection circuits utilized in conjunction with optical disks.

This thesis presents the very first bionics chemical synapse which has the capability to sense the neurotransmitter (glutamate) and imitates the physiological behaviour of certain chemical synapse receptors (i.e. AMPA, NMDA, GABAA and GABAB). This bionics chemical synapse consists of two main parts: the glutamate ISFETs that act as neurotransmitter sensors and the current-mode CMOS circuits that have been designed to match the physiological behaviour of the chemical synapses. This bionics chemical synapse requires a sub-nano Siemens operational transconductance amplifier (OTA) to develop a low conductance gain for each chemical synapse receptor (0.1nS). A combination of two OTA designs was required to decrease the overall transconductance gain, which were: the bulk driven transistor and the drain current normalisation. To create the bionics chemical synapse, a neurotransmitter sensor is required as the chemical front-end for each receptor circuit. The sensor that was used is an enzyme-modified ...

Negative differential transconductance in silicon quantum well metal-oxide-semiconductor field effect/bipolar hybrid...Negative differential transconductance in silicon quantum well metal-oxide-semiconductor field effect/bipolar hybrid...
Introducing explicit quantum transport into Si transistors in a manner amenable to industrial fabrication has proven challenging. Hybrid field-effect/bipolar Si transistors fabricated on an industrial 45 nm process line are shown to demonstrate explicit quantum transport signatures. These transistors incorporate a lateral ion implantation-defined quantum well (QW) whose potential depth is controlled by a gate voltage (V{sub G}). Quantum transport in the form of negative differential transconductance (NDTC) is observed to temperatures ,200 K. The NDTC is tied to a non-monotonic dependence of bipolar current gain on V{sub G} that reduces drain-source current through the QW. These devices establish the feasibility of exploiting quantum transport to transform the performance horizons of Si devices fabricated in an industrially scalable manner. ...

A transimpedance amplifier for capacitive micromachined ultrasonic transducersA transimpedance amplifier for capacitive micromachined ultrasonic transducers
In this thesis a design of a CMOS transimpedance amplifier (TIA) for a capacitive micro-machined ultrasonic transducer (CMUT) is presented. CMUTs have a high electrical impedance when used as receivers. Any capacitance between the CMUT and a high impedance amplifier will degrade the frequency response. So, we need to amplify the current rather than the voltage. This approach requires a transimpedance amplifier. The designed TIA has a 30 MHz bandwidth and 400 kΩ transimpedance gain. The total input referred current noise of the TIA is 270 fA/√Hz at 10 MHz. The noise figure of the TIA is 2.7 dB at 10 MHz when connected to the CMUT with 200 kΩ source resistance. The power consumption of the TIA is 10.5 mW and the size of the TIA layout is 133µm x 45µm. The TIA chip will be fabricated in AMS C35B4C3 (0.35µm) process ...

Solvent effects in oscillator/amplifier configured dye lasers - NASA/ADSSolvent effects in oscillator/amplifier configured dye lasers - NASA/ADS
While it is usually necessary to use separate oscillator and amplifier cells in the optimization of the output of dye lasers excited by high powered pump lasers, under the assumption that the dye-solvent combination yielding maximum oscillator output is also optimal for use in the amplifier, attention is presently given to a case in which two different solvents optimized the output of an oscillator/amplifier dye laser over a region of its tuning range. In addition to increasing either output or tuning range, this method may allow the use of less expensive or toxic dye-solvent mixtures in at least one stage of the dye laser.

Pass Labs a40 amplifier parts & vendor listPass Labs a40 amplifier parts & vendor list
Amplifier Description:. The Pass Labs a40 is a high current, pure Class A (simple design, low distortion, lots of heat) stereo amplifier that uses bipolar junction transistors (BJTs) in a push-pull configuration for the output stage. My completed amp is biased just a little higher than spec and delivers approximately 50wpc into either an 8ohm or 4ohm load (measured with a scope). Each channel uses two pairs (two push, two pull) of darlington (essentially two BJT transistors in a single package) output transistors and dissipates approximately 100 watts all of the time. Total draw from the wall is approximately 190 watts (1.57A) for the completed stereo amp (bias adjusted for transistor substitution). Each channel has 112,000uF of capacitance, runs on +/-32v power supply rails, and is biased at about 3.15A, or 0.78A per output transistor. (The original design specifies +/-30v rails, and 0.8A bias per transistor, or 3.2A per channel.) At 0.78A bias, each of the transistors in the output stage will ...

Beating battery drain - Science and Technology Research NewsBeating battery drain - Science and Technology Research News
Stream video on your smartphone, or use its GPS for an hour or two, and youll probably see the battery drain significantly. As data rates climb and smartphones adopt more power-hungry features, battery life has become a concern. Now a technology developed by MIT spinout Eta Devices could help a phones battery last perhaps twice as long, and help to conserve energy in cell towers.. The primary culprit in smartphone battery drain is an inefficient power amplifier, a component that is designed to push the radio signal out through the phones antennas. Similar larger modules are found in wireless base stations, where they might use 10 or even 100 times the power.. Prepared to send sizeable chunks of data at any given time, the amplifiers stay at maximum voltage, eating away power - more than any other smartphone component, and about 75 percent of electricity consumption in base stations - and wasting more than half of that power as heat. This means smartphone batteries lose longevity, and base ...

Gain (electronics) - WikipediaGain (electronics) - Wikipedia
In electronics, gain is a measure of the ability of a two-port circuit (often an amplifier) to increase the power or amplitude of a signal from the input to the output port[1][2][3][4] by adding energy converted from some power supply to the signal. It is usually defined as the mean ratio of the signal amplitude or power at the output port to the amplitude or power at the input port.[1] It is often expressed using the logarithmic decibel (dB) units (dB gain).[4] A gain greater than one (greater than zero dB), that is amplification, is the defining property of an active component or circuit, while a passive circuit will have a gain of less than one.[4]. The term gain alone is ambiguous, and can refer to the ratio of output to input voltage (voltage gain), current (current gain) or electric power (power gain).[4] In the field of audio and general purpose amplifiers, especially operational amplifiers, the term usually refers to voltage gain,[2] but in radio frequency amplifiers it usually refers ...

802.11p Spectral Emission Mask Testing802.11p Spectral Emission Mask Testing
IEEE 802.11p [ 2 ] is an approved amendment to the IEEE 802.11™ standard to enable support for wireless access in vehicular environments (WAVE). Using the half-clocked mode with a 10 MHz channel bandwidth, it operates at the 5.85-5.925 GHz bands for which additional spectral emission masks are defined [ Annex D of 1 ].. This example shows how spectral mask measurements can be performed on a transmitted waveform. The waveform is generated with WLAN System Toolbox™ for simplicity, but a waveform captured with a spectrum analyzer could be used as well.. A waveform consisting of three 10 MHz IEEE 802.11p packets separated by a 32 microsecond gap is generated. Random data is used for each packet and 16QAM modulation is used. The baseband waveform is upsampled and filtered to reduce the out of band emissions thereby meeting the spectral mask requirements. A high power amplifier (HPA) model is used, which introduces inband distortion and spectral regrowth. The spectral emission mask measurement is ...

CryoprotectantCryoprotectant
Conventional cryoprotectants are glycols (alcohols containing at least two hydroxyl groups), such as ethylene glycol[citation needed], propylene glycol and glycerol. Ethylene glycol is commonly used as automobile antifreeze; while propylene glycol has been used to reduce ice formation in ice cream. Dimethyl sulfoxide (DMSO) is also regarded as a conventional cryoprotectant. Glycerol and DMSO have been used for decades by cryobiologists to reduce ice formation in sperm,[2] oocytes,[3] and embryos that are cold-preserved in liquid nitrogen. Cryoconservation of animal genetic resources is a practice that involves conventional cryoprotectants to store genetic material with the intention of future revival. Trehalose is non-reducing sugar produced by yeasts and insects in copious amounts. Its use as a cryoprotectant in commercial systems has been patented widely. ...
