US Patent:

44576005, Jul 3, 1984

Filed:

Oct 13, 1981

Appl. No.:

6/310528

Inventors:

Joseph F. Hall - Laguna Niguel CA

International Classification:

G03B 2100

US Classification:

353122

Abstract:

A light directing system includes a reflector whose shape in the direction from pole to open end varies from parabolic to elliptical with successively nearer remote foci. The output of the reflector is focused to a common focal point in a lens whose magnification varies from negative to positive in the radial direction from central to outer regions of the lens. The marginal part of the output beam is added to the central part of the beam in a mirror system. The resultant beam is then divided and recombined in an amorphics integrating lens system and then transferred to a film gate and projection lens set.

International Classification:

G08B 1700

US Classification:

340584

Abstract:

An infrared sensor is particularly well suited for the detection of heat sources, specifically from fires. It comprises an infrared detector receiving infrared radiation from a focused refractive optical unit. An optical chopper and electronic amplifier enable the sensor to operate without drift and with immunity to temperature changes in the sensor itself. The infrared radiation from the optical unit is appropriately filtered so as to optimize reception in a frequency band between 2. 6 and 2. 8 microns. In this band, there exists negligible energy from the sun due to absorption by gas molecules in the earth's atmosphere. Consequently, the sensor can be used in full sunlight without becoming saturated by the large magnitude infrared radiation of the sun. The sensor contains circuitry providing an audible output signal whose pitch is proportional to the intensity of the infrared radiation received from nearby heat sources. The device does not require any visual attention from a firefighter.

Abstract:

A new biostable glucose permeable polymer has been developed which is useful, for example, in implantable glucose sensors. This biostable glucose permeable polymer has a number of advantageous characteristics and, for example, does not undergo hydrolytic cleavage and degradation, thereby providing a composition that facilitates long term sensor stability in vivo. The versatile characteristics of this polymer allow it to be used in a variety of contexts, for example to form the body of an implantable glucose sensor. The invention includes the polymer composition, sensor systems formed from this polymer composition, and methods for making and using such sensor systems.
