    Abstract: An antenna apparatus that can increase capacity in a cellular communication system. The antenna operates in conjunction with a mobile subscriber unit and provides a plurality of antenna elements, each coupled to a respective signal control component such as a phase shifter. The phase shift for each antenna element is programmed for optimum reception during, for example, an idle mode when a pilot signal is received. The antenna array creates a beam former for signals to be transmitted from the mobile subscriber unit, and a directional receiving array to more optimally detect and receive signals transmitted from the base station. By directionally receiving and transmitting signals, multipath fading is greatly reduced as well as intercell interference. The phase shifters are adjusted in a coarse and a fine mode. In the coarse mode all phase shifters are jointly incremented through several phase shift values until a signal quality metric is optimized. The coarse adjustment mode is followed by a fine adjustment mode during which the phase shifters are independently adjusted to further optimize the signal quality metric.

    Abstract: A technique for encoding a signal used in a digital communication system in which individual traffic channel data rates may be adapted to specific channel conditions. In particular, a forward error correction coding rate is adapted for individual channels while at the same time maintaining a fixed block size independent of the FEC coding rate. This allows the system data rate to adapt to the channel conditions experienced by a specific user. Thus, users experiencing good communication conditions with low multipath distortion may be allocated higher capacity, whereas users with significant multipath distortion may make use of lower rate (higher levels of coding) error codes to maintain high quality. Messages are sent from a transmitter to a receiver to inform the receiver of the coding rate implemented at any given point in time. These parameters may be adjusted independent of transmitted power level through the expedient of ensuring that size of a transmitted frame remains constant, while permitting the ability to change FEC coding rates and FEC block sizes.

    Abstract: An infra-red proximity fuze system for a homing missile is provided that has Mercury Cadmium Telluride detector cells cooled to at least −40° C., and a frequency response range of 5-7 microns, so as to be sensitive to target skin radiation due to kinetic heating and insensitive to jet-exhaust plume radiation. Three optics/detector modules are equidistantly spaced around the missile axis and each has first and second detector elements the three first elements being connected in a common channel to constitute a guard beam and the three second elements being likewise connected to constitute a firing beam, the guard beam field being displaced angularly from the firing beam field in the forward missile axis direction by about 6°.

    Abstract: A system causes a scan angle of a directional antenna to change temporarily from a current scan angle to at least one trial scan angle during reception of predetermined portions of an information carrying signal. At the trial scan angle(s), a trial metric associated with each trial scan angle is determined by the system. The system then selects a next scan angle based on the trial metrics. Examples of predetermined portions of the information carrying signal include the Power Control Bit (PCB) and Forward Error Correction (FEC) block.

    Abstract: A transparent vinyl pouch is mounted on the lower back of a motorcycle jacket to allow the driver to further customize his/her motorcycle. The pouch carries the license plate in order to keep the customized motorcycle tag-free, or is interchangeable with other customized plates, which complement the driver's helmet and/or motorcycle. The pouch also serves to provide greater visibility to the license plate. The pouch is worn on the lower back so other drivers can easily see it. In alternative embodiments of the present invention, there may be hooks inside the pouch, which serve as additional support of the license plate, and there may be lights centered about the license plate, or reflective paint used in order to increase visibility of the plate at nighttime or in bad weather conditions. The pouch closure may also have a locking device to prevent the closure (zipper or hook-and-loop closure) from opening and therefore preventing loss or theft of the license plate.
