Abstract: State of test points on an integrated circuit are encapsulated in a telemetry frame that is wirelessly conveyed to a test system. Test points may be logic levels or analog levels converted into representative multi-bit values. Conveyance off the circuit may be by radio frequency or optical emission.

Abstract: A dielectric device for protecting animals from becoming a short between power lines and poles or other lines.
In an alternate embodiment the device includes prongs to deter birds from landing on the protection device.
Abstract: Phase-locked-loop based data and clock extraction comprising a phase detector that generates up and down pulses. Down pulses are maintained in width approximately equal to 1.5 unit intervals of a local sampling clock. Up pulses are allowed to vary with the phase relationship between the local sampling clock and an incoming encoded bit stream. The up pulses are allowed to vary between 1 and 2 unit intervals of the local sampling clock. The up and down pulses drive a charge pump D/A converter that generates a control voltage. The control voltage sets the frequency of the local sampling clock generated by a voltage controlled oscillator. Shift register controlled by a state machine and clocked by the local clock allows reception of complex data packets arriving by the encoded bit stream.
Abstract: The present invention combines a small, compact, light-in-weight television receiver with a positioning mechanism that allows the television viewer to orient the television screen to suit her own comfort. The small size of the television receiver is intended to service only a few viewers at a time. Since the present invention utilizes a small, lightweight television receiver, a much more agile positioning mechanism can be employed.The television receiver is supported in space by the articulation mechanism. The articulation mechanism can be attached to a wall, the headboard of a bed, to a piece of medical equipment, or to any other fixed object. An umbilical cable is drawn through the articulation mechanism and connects the television receiver to a power adapter. The power adapter accepts utility power from household convenience outlets and draws television signals from an antenna or a cable television outlet.
