    Abstract: Methodology, and associated circuitry, for encoding (e.g., 200) and decoding (e.g., 900) an incoming data stream (201) utilize a coordinated code constellation (e.g., Fig. 3) that effects robust signal detection in the presence of channel interference. The encoder (220) partitions the incoming data stream into contiguous data segments in proportion to the number of levels for a given coordinated code. Each data segment is mapped with reference to the coordinated code to signal levels suitable for transmission over a plurality of channels (e.g., 222, 223). The decoder measures (e.g., 900) the received signals on the channels and estimates noise statistics for the channels. A metric relationship engendered by the coordinated code is evaluated with reference to the received signals, estimates to the received signals, and the noise statistics. An output data stream is then generated based on the evaluation of the metric.

    Abstract: A front projection video display system (100) achieves high contrast without darkened ambient room conditions by a specific combination and arrangement of the components of this system. These components include a front-projection video projector (10) which projects an image of particular direction of polarization; polarizing lenses (30) which polarize light radiated from room light fixtures in a direction orthogonal to that of the projected image; a polarizing filter (40) which substantially transmits light polarized parallel to the projected image and substantially blocks light orthogonal to the projected image; and a projection screen (20) which is polarization maintaining and which receives the projected image for viewing by the viewing audience.

    Abstract: A methodology and concomitant circuitry (1000) for smoothing delay sensitive traffic utilizes short term traffic forecasts and guarantees meeting a prespecified delay constraint. The pattern of incoming traffic is used to forecast estimates of future incoming data from the present and past incoming data. Corresponding to the estimate is a data rate for propagating stored data to produce a smoothed outgoing data rate, and the interval of time over which such a rate is used so as to satisfy the delay constraint. The estimation procedure is then re-invoked at the end to the time interval, which takes into account data arriving during the time interval, so as to determine the next succeeding data rate and a new time interval for propagating stored data.

    Abstract: A film of linear organosilsesquioxane polymer, or 'ladder' organosiloxane, coated upon the surface of an LiMn2O4 secondary battery electrode (19) and cured to a glassy layer is subjected to plasma oxidation to remove pendant organic groups comprising the coated polymer. The resulting ultrathin silica separator layer (17) is replete with minute pores which take up and retain by capillarity a typical LiC1O4 electrolyte solution. A counter-electrode (15) placed in intimate contact with the silica electrolyte element completes a secondary battery structure (10) in which lithium ions readily migrate through the electrolyte during repeated discharge/charge cycles without loss of element integrity or efficacy.

    Abstract: A method of fabricating a self-aligned gated electron field emitter. An oxidation process forms an optimized, atomically sharp needle (18) in a silicon substrate (12). The needle and surrounding planar area is conformally coated with silicon dioxide (22). A dielectric layer (24) is deposited and planarized over the needle. The dielectric layer is partially etched away to expose the coated needle. The exposed silicon dioxide needle is isotropically etched so as to undercut the dielectric layer. A gate metal is directionally deposited so as to form a gate layer (26) on the planar portions of the dielectric layer that is electrically isolated from the gate metal (28) deposited on the needle. The metal on the needle is anodically etched by applying the potential only to the silicon and not to the gate layer. Electro-plating may recoat the needle with another metal (30). The silicon substrate may be replaced by a glass substrate (42) on which is deposited a polysilicon or amorphous silicon layer (40).

    Abstract: A compensator for thermal or other uncontrollable effects in a liquid-crystal etalon filter (10). The narrow pass band of the filter is controlled by adjusting the amplitude (48) of an AC drive signal (44, 46) applied to the electrodes (22, 24) on either side of the liquid crystal (26) in the filter. An optical detector (36) detects the intensity of light (30) from a narrow-bandwidth input beam (34) passed by the detector. Electrical circuitry (40) determines the bipolar amplitude of the component of the light intensity that is at twice the frequency of the AC drive signal (the doubled-frequency amplitude) and adjusts the amplitude (48) of the AC drive signal in response to the doubled-frequency amplitude so as to reduce the doubled-frequency amplitude toward zero.
