Any device or element which converts an input signal into an output signal of a different form. Examples include the microphone, phonographic pickup, loudspeaker, barometer, photoelectric cell, automobile horn, doorbell, and underwater sound transducer. (McGraw Hill Dictionary of Scientific and Technical Terms, 4th ed)
The recognition of professional or technical competence through registration, certification, licensure, admission to association membership, the award of a diploma or degree, etc.
It is a form of protection provided by law. In the United States this protection is granted to authors of original works of authorship, including literary, dramatic, musical, artistic, and certain other intellectual works. This protection is available to both published and unpublished works. (from Circular of the United States Copyright Office, 6/30/2008)
Compliance with a set of standards defined by non-governmental organizations. Certification is applied for by individuals on a voluntary basis and represents a professional status when achieved, e.g., certification for a medical specialty.
Critical analyses of books or other monographic works.
The guidelines and policy statements set forth by the editor(s) or editorial board of a publication.
Exclusive legal rights or privileges applied to inventions, plants, etc.

The specialty related to the performance of techniques in clinical pathology such as those in hematology, microbiology, and other general clinical laboratory applications.
Property, such as patents, trademarks, and copyright, that results from creative effort. The Patent and Copyright Clause (Art. 1, Sec. 8, cl. 8) of the United States Constitution provides for promoting the progress of science and useful arts by securing for limited times to authors and inventors, the exclusive right to their respective writings and discoveries. (From Black's Law Dictionary, 5th ed, p1014)
The genus Lepus, in the family Leporidae, order LAGOMORPHA. Hares are born above ground, fully furred, and with their eyes and ears open. In contrast with RABBITS, hares have 24 chromosome pairs.
A subfield of acoustics dealing in the radio frequency range higher than acoustic SOUND waves (approximately above 20 kilohertz). Ultrasonic radiation is used therapeutically (DIATHERMY and ULTRASONIC THERAPY) to generate HEAT and to selectively destroy tissues. It is also used in diagnostics, for example, ULTRASONOGRAPHY; ECHOENCEPHALOGRAPHY; and ECHOCARDIOGRAPHY, to visually display echoes received from irradiated tissues.
Advanced technology that is costly, requires highly skilled personnel, and is unique in its particular application. Includes innovative, specialized medical/surgical procedures as well as advanced diagnostic and therapeutic equipment.
Fabric or other material used to cover the body.
