Abstract: A multi-band focal plane array architecture operative to detect multiple spectral image. The multi-band focal plane array architecture has an integrated readout circuit, a plurality of first detectors integrated in the readout circuit and a plurality of second detectors deposited on the readout circuit. Preferably, the first detectors are operative to detect visible signals and the second detectors are operative to detect infrared signals. The first and second detectors are arranged in a checkerboard pattern, in alternate rows or columns, or at least partially overlapped with each other to realize simultaneous detection in two different wavelength bands. The architecture may also have an additional integrated readout circuit flip-chip bonded to the integrated readout circuit. By forming a plurality of third detectors on the additional integrated readout circuit, a tri-band focal plane array may be realized.

Abstract: A target illuminating system is provided for steering a scan optical beam and reducing the size of an optical output aperture. The system includes an array of scan beam outlets being selectively operative to receive and project a point source of scan beam radiation along an optical path. The system also includes a collimating element being disposed along the optical path. The collimating element is operative to receive the point source of scan beam radiation and to output the collimated scan optical beam in a desired coarse direction corresponding to a selected one of the scan beam outlets. The scan optical beam defines a scan exit pupil which is substantially coincident with the optical output aperture.

Abstract: Method and apparatus for mounting a sample comprising a crystal for X-ray crystallographic analysis, a method for aligning a sample comprising a crystal for X-ray crystallographic analysis, which sample is mounted on a positioning device, and a method for determining the structure of a sample containing a crystal by means of X-ray crystallography.

Abstract: A laser system for operation at elevated temperatures with minimal cooling requirements. The laser system comprises a laser media having first and second optical ends and an input port. The laser system further comprises at least one high-temperature laser diode which optically communicates with the laser media and is operative to generate a source beam of light which is transmitted into the input port of the laser media. Optically communicating with the first optical end of the laser media is at least one reflector, while optically communicating with the second optical end of the laser media is at least one optical coupler. The laser media, the reflector and the optical coupler are configured to form a laser resonator operative to generate a laser beam which is transmitted through the optical coupler.

Abstract: Infrared radiation from a light source such as a laser diode illuminates the field of view of a surveillance camera. The amount of illumination is varied in intervals, which may for example, be about 3/4 of a second, by varying the power applied to the light source. The radiation may emanate from optical fibers surrounding a camera lens, or through other ports. The power to the laser diode may be altered in response to background light sensed by a photo cell. A filter on the camera preferentially passes reflected illumination of the source while alternating background illumination.

Abstract: A barricade post for supporting a reflectorized panel and warning light comprising an integrally formed member molded of a elastomeric material having a generally U-shaped cross-section. The upper end of the post defines a shoulder to support a warning light. The intermediate section of the post is generally of uniform cross-section and is adapted for securement of the reflectorized panel by bolts or similar mechanical fasteners. The lower pedestal portion of the post diverges outwardly and termimates at a base. The lower pedestal portion is reinforced by diagonally extending ribs so the unit will resist breaking if impacted by a vehicle.

Abstract: A lounge having an angularly adjustable main forward section and a plurality of side-by-side longitudinal rearwardly extending additional sections adjustably pivotally connected to the main forward section, each longitudinal section consisting of a plurality of independently angularly adjustable articulated segments. Manually controlled means are provided for locking the main forward section and the longitudinal sections and articulated segments in adjusted positions to provide a selected desired surface contour, for example, to facilitate achievement of desired positions in the performance of sexual acts.

Abstract: A long-handled dispenser device for applying lotion or other liquid material to parts of the body. The device consists of a long arcuately curved tubular handle employed as a reservoir for the material, with a screw plug at its free end. The handle is attached to a head member having a large applicating sponge. The head member has a plunger-operated suction pump connected to rigid inlet tubing extending through the handle to its free end region. The pump has a discharge spout directed into the sponge. A snap-on detachable cover tray is provided on the head member, serving as a lotion-collecting receptacle to receive lotion from the pump when the pump is actuated, to form a shallow pool to moisten the bottom portion of the sponge. For applying the lotion, the tray is detached from the head member. Subsequently the sponge may be dipped into the tray for remoistening.

Abstract: An adaptor to be used with a standard telephone to enable a plug-in headset to be used therewith without interfering with normal usage of the telephone and to allow usage without the necessity of employing the normal telephone handset, enabling free use of the user's hands. The attachment includes a latching push-button which operates a switch assembly which duplicates the function of the telephone hook switch assembly. The attachment is mounted on a bracket which is clampingly engageable with the telephone and which carries the jacks for the plug-in headset and the latching push button and substitution switch assembly. The attachment allows simultaneous use of the plug-in headset and the normal telephone handset by two persons for a conference call.
