Abstract: A method of generating video data for transmission to a user particularly for use in a video surveillance system. The method comprises generating a first representation of a first image and one or more further representations of the first image are then generated, said further representation(s) being predicted from a previously generated representation of the first image. In response to a request for a subsequent image, a first representation of said subsequent image being predicted from a representation of the first image. Then one or more further representations of said subsequent image are generated, said further representations of said subsequent image being predicted from a previously generated representation of said subsequent image. Thus, the same source data for a first image is fed into the encoder, so producing a progressive still image at the decoder. When a different image is required, the encoder substitutes, as the input to the encoder, the source picture from the requested point in time. This source picture is encoded predictively from the original image

Abstract: A device for converting binary logic pulses into an output current and the output current being switchable between a positive and negative polarity. The device provides a charge pump circuit which is suitable for the phase-detector stage in a phase-locked loop (PLL) circuit. The charge pump circuit comprises an input stage for the "UP" binary logic pulses and a second stage for the "DOWN" binary logic pulses. The input stages comprise emitted-coupled transistor pairs. The circuit includes current sources and current sinks for generating the output current in the input stages in response to the binary logic pulses. The circuit features a pair of switch diodes coupled between the outputs of the input stages. The diodes form a commutator which controls the direction of the output current and the leakage current during the idle states. The circuit also includes a clamping circuit to limit the voltage swing across the switching diodes. The charge pump circuit according to the present invention exhibits a fast response time, a symmetrical response to the binary logic pulses, and virtually zero leakage current in the idle state. The charge pump circuit utilizes non-complimentary bipolar processes and is suitable for a monolithic integrated circuit implementation.

Abstract: A hook and loop detachable and re-attachable pad apparatus that is applied to furniture to protect flooring surfaces and make sliding furniture easier, has a hook material on a plate that attaches to the furniture to which a separate loop pad, made of loop material, attaches. The loop pad is detachable and re-attachable and may have loop material on both sides. Alternatively, a loop plate applied with loop material may attach to the furniture and have a separate, hook and loop combination pad that attaches to it. The combination pad has one side that is hook material and one side that is loop material so that additional hook and loop combination pads may be stacked on top of the prior pad to provide a thicker cushion to account for pad compression due to heavier pieces of furniture or to slightly raise pieces of furniture to better suit a user.

Abstract: A device for restoring DC and non-zero average components of a serially transmitted binary signal which has been AC coupled. The device comprises an input port for the binary signal, a clamping circuit, a feedback network, a summing node, and an output port. The input port includes a capacitor for coupling the binary signal to the summing node and the clamping circuit. The feedback network includes an input and an output which are also connected to the summing node. The clamping circuit clamps the positive and negative peaks of the AC coupled binary signal which exceed a predetermined range. The feedback network latches the AC coupled binary signal and produces a current signal. For a binary signal which is within the predetermined range, the clamping circuit exhibits a very high input impedance, thereby causing the current signal to charge the coupling capacitor and produce a voltage which is added to the AC coupled binary signal at the summing node. The output port includes a comparator which converts the restored AC coupled binary signal to digital logic levels. In another embodiment, the clamping circuit includes a current sensor for producing an amplitude signal which is indicative of the amplitude of the AC coupled binary signal. The amplitude signal is fed to an automatic gain controller which produces a gain control voltage for controlling the operation of a high frequency equalizer.
