Abstract: A knife has a handle with an enlarged proximate end grip portion having ribbed and unribbed surfaces. The handle has oppositely disposed thumb receiving concave unribbed surfaces at the distal end for alternate pinch-grip functions. The knife blade has a cutting edge that extends proximately below and adjacent the enlarged grip portion, and is proximately disposed with respect to the thumb receiving pinch-grip concave surfaces. The knife provides diverse impaired grip cutting functions with comfort and with fatigue.

Abstract: Multiple-input/multiple-output (MIMO) antenna technology is used in a point-to-point radio link to provide higher data rates than would otherwise be achievable in a similar system that did not use MIMO antenna technology. Particular embodiments of the invention implement channel coding, dual polarization, adaptive receiver combining and adaptive power control.

Abstract: A shoulder pad includes a flexible base member having a top surface, a bottom surface, a central portion, opposite first and second free ends and a longitudinal axis. The flexible base member includes a plurality of longitudinally space, oval-shaped pad sections that increase in thickness from the central portion of the shoulder pad toward at lease one of the first and second free ends. The longitudinally spaced pad sections may also increase in durometer hardness from a centermost pad section to the longitudinally outermost pad sections. For attachment of the pad to a shoulder strap, the pad includes at lease one clip from making snap-on engagement with the pad. For added durability, the shoulder pad further preferably includes a thin spine, which is more rigid than the flexible base member and is attached to the top surface of the flexible base member.

Abstract: A system and method for generating a coherent reference signal for extracting desired user signals from received signals even after error propagation is underway, are presented. A data symbol preceding a sequence whose relative phases are known is used as an absolute phase reference. Since errors in detection of the phase reference symbol are usually caused by error propagation already underway, the sequence can be used to reacquire the desired signal with merely an absolute phase shift in detected data, which allows accurate differential detection of the desired user signal even in the absence of absolute phase knowledge.

Abstract: A system and method for applying channel weights in a communication system are presented. The application of weights derived from a sample window is time-shifted into that sample window, decreasing the effects of channel variation and partially compensating for degradation due to differential detection.

Abstract: An adaptive high speed data transmission system is described. In one aspect, the transmitter for this system employs a plurality of transmit antennas which have controllable offsets. The transmitter also includes signal coding circuitry suitable for use to address transmission impairments due to fast fading in the transmission channel. At the receiver, the received signal is analyzed to determine the fading characteristics of the channel. Where slow fading is detected, the offsets are employed to convert the slow fading into fast fading. The channel characteristics are continually resampled and these characteristics are used to adjust the transmitter and the receiver to achieve optimal transmission speed.
