A disposable cap for a body temperature detector includes a body having a viewing end and a retaining end. The retaining end includes an inward protrusion that expands over a wider portion of an end of the detector and contracts after the retaining end has passed over the wider portion to snugly secure the cap on the detector. The cap further includes a flange with an aperture therethrough adjacent the viewing end to permit a radiation sensor of the detector to view a target surface. Preferably,...

A temporal compression and decompression system is disclosed for color video. A video stream with red, green and blue pixel element values is input to a first computer. In the first computer, a new frame of video data is compared to the frame being displayed on a second computer and the similarity between corresponding blocks and sub-blocks is represented with one tolerance result per sub-block. Based on the number of sub-blocks for which tolerance results exceed a preset threshold and a user-sp...

A space-time signal processing system with advantageously reduced complexity. The system may take advantage of multiple transmitter antenna elements and/or multiple receiver antenna elements, or multiple polarizations of a single transmitter antenna element and/or single receiver antenna element. The system is not restricted to wireless contexts and may exploit any channel having multiple inputs or multiple outputs and certain other characteristics. Multi-path effects in a transmission medium ca...

Temporal drift correction may be provided in a real-time audio communication system by measuring a size of a receiving data buffer and comparing that size to a predetermined nominal data buffer size. An amount of temporal drift is characterized as a number of samples per audio playback data block based on the measured data buffer size and the nominal data buffer size. A number of samples to be inserted or removed for each audio playback data block to correct the temporal drift may be determined,...

File accesses initiated by a graphical user interface are monitored. When the number of accesses exceeds a specified threshold number of times in less than a specified period of time, and that file is not already represented on the computer desktop, an icon representing that file may be placed on the computer desktop. The user may be queried to determine if an icon representing that file should be placed on the desktop. If a particular icon residing on the computer desktop has not been used more...

A post-correlation nulling circuit (10) derives from a narrowband jammer a replica of the baseband jammer noise which is used to adaptively cancel the jammer noise waveform in the receiver baseband after PN processing, thus allowing the adaptive antenna spatial nulling to concentrate on canceling wideband jammers. In particular, the post-correlation nulling circuit (10) includes a correlator (14) for correlating the received interference signal and received code modulated signal with a replicate...

A system, apparatus and methods are disclosed for the spatial and temporal processing of time dependant array data using analog signal processors. In one embodiment, a programmable array of switched capacitors is used to provide tunable parameters for controlling the desired processing of input data streams. The switched capacitor implementation of a spatial filter provides a massively parallel device that can be programmed to perform isotropic and spatially-oriented anisotropic filtering with l...

A temporal imaging system is presented consisting of a dispersive input path, a phase modulator producing a phase modulation substantially equal to A+Bt.sup.2, and an output dispersive path. This temporal imaging system can be combined with other temporal lenses to image input signals in the same manner that spatial lenses can be used to image light from spatial sources. In particular, this temporal imaging system can be used to expand, compress and or invert input temporal signals.

The memory (80) is intended to be read or modified by an electronic logical system of a pocket calculator. It comprises a plurality of bistable electromechanical flip-flop circuits (82). Each flip-flop circuit (82) comprises an input for setting at 1 (S) and an input for setting a zero (R) and an output (78). The inputs are connected individually to a multiplexor (702) controlled by a control circuit (701). The control circuit (701) is connected in two directions with a central processor via a b...
