Abstract: The present invention is directed to an uncooled, infrared detector which includes a sensor having an amorphous surface layer containing organic carbon and a high dopant concentration which possesses an improved temperature coefficient of resistivity, as well as improved responsivity, and which may be patterned to form a focal plane array by means of common microlithographic techniques. The present invention is additionally directed to an “ion beam mixing” process for preparing the present infrared sensor.

Abstract: A series of polyethylene glycol derivatives possessing a diene moiety has been prepared and characterized. The reactivities of these derivatives in various Diels-Alder reactions have been demonstrated. The potential derivatives, which can be made by various Diels-Alder reactions, are expected to be useful in biotechnical applications.

Abstract: A system and method for assessing breathing and vocal tract sound production of a user. The system comprises a first sensor generating a vocal tract sound signal representing vocal tract sounds produced by the user, a second sensor generating a breathing signal representing breathing movement of the user, and a signal processing unit for processing the vocal tract sound and breathing signals. The method comprises the steps of sensing vocal tract sounds produced by the user and providing a vocal tract sound signal representative thereof, sensing breathing movement of the user and providing a breathing signal representative thereof, receiving the signals via an analog input for processing the signals, generating a combined signal by superimposing the vocal tract sound and breathing signals, and displaying the combined signal to the user.
