    • A method, apparatus, and system are described in which products from a solar assisted Reverse Water Gas Shift (RWGS) reaction are used in a hydrocarbon fuel synthesis process to create a liquid hydrocarbon fuel. A water splitter splits water molecules into hydrogen and oxygen via the addition of the solar energy. A chemical reactor chamber mixes solar heated carbon dioxide gas with all or just a portion of the hydrogen molecules from the water splitter in a RWGS reaction to produce resultant carbon monoxide. A hydrocarbon liquid fuel synthesis reactor receives and uses either 1) all of the unconsumed portions of hydrogen from the RWGS or 2) the remaining portion of the hydrogen molecules from the water splitter and the resultant carbon monoxide molecules from the RWGS in the hydrocarbon fuel synthesis process to create a liquid hydrocarbon fuel.

    • Systems and methods are disclosed for improving DSL performance, including ADSL and VDSL performance, over a local loop between a telephone company central office and a customer premises. In particular, a loop extender is coupled to the local loop and differentially amplifies downstream and upstream DSL signals to at least partially compensate for DSL signal attenuation that occurs as DSL signals pass over the local loop. Pursuant to one embodiment, the loop extender includes an upstream filter/amplifying equalizer, a downstream filter/amplifying equalizer, a differential amplifier pair, an inverting amplifier, and a pair of electromagnetic hybrids, which couple the loop extender to the loop and provide upstream and downstream signal amplification. In another embodiment, the loop extender includes POTS loading coils to improve the POTS or voice band transmission over the local loop. According to this embodiment, the loop extender provides both improved POTS band signal transmission and DSL service.

    • A method is disclosed for maintaining loop stability between a transmit and a receive path of a speaker phone which is capable of operating in either a full-duplex or a half-duplex mode. Loop stability is maintained and normal operation is achieved by controlling transmit and receive path attenuators. The method first determines whether feedforward or feedback signal levels should be used. Based on this determination, the signal and noise parameters along various points in the transmit and receive path are evaluated. Based on the parameter values, the transmit and receive attenuators are adjusted to maintain loop stability and to operate the speaker phone in the proper state. Additionally, when the speaker phone adjusts the transmit attenuator for greater signal attenuation in order to maintain loop stability the noise fill-in component of the speaker phone will generate additional background noise to maintain a constant background noise level, as perceived by the far-end user.

    • An apparatus and method for communicating image sequences through a bandwidth limited channel have circuitry for estimating, for successive images of the sequence, a motion vector field. The motion vector field measures the motion displacement between successive images of the sequence for block regions of the image. A lossy coding circuitry represents the sequentially generated motion vector field for an image as a coded motion signal. An error reconstruction circuitry generates an error signal in response to the vector field coded motion signal and a channel encoder transmits the motion vector field coded signals and the error coded signals over the channel to a receiver. At the receiver, the transmitted error and motion coded signals are received and decoded, and a received image is derived therefrom. The lossy coding circuitry can be any of a number of different circuitries, and in particular, block transform coding can be employed. The transformed coding methods and apparatus are selected to avoid artifacts in the motion vector field and coding process such as blocking effects.

    • An image sequence transmission method and apparatus transmit a sequence of successive images over a bandwidth limited channel. The transmitter has a motion estimator for estimating the motion displacement between successive image frames of the sequence. The motion estimator divides each image into nonoverlapping blocks, each block including a plurality of picture elements. The apparatus then successively selects, in accordance with a steepest descent estimation technique, an initial value of a motion vector displacement for each successive block. Thereafter, an iterative process determines using the steepest descent approach, successive values of the motion displacement vector for a block and the iteration process is terminated when an iteration error measure, which is associated with the steepest descent method, is less than a predetermined threshold value. In particular embodiments of the invention, an adaptive approach is used wherein the step size parameter is incremented in accordance with a gradient error used in the steepest descent technique. In addition, methods and apparatus for determining an initial motion vector field value based upon of the motion displacements in adjacent blocks advantageously determine the initial displacement vector for a block.
