Abstract: A control system for a work machine, having an articulated joint and a work implement with at least one axis of rotation, has a first lever with a first longitudinal axis. A twist angle of the first lever about the first longitudinal axis is related to an articulation speed of the work machine. The control system also has a second lever having a second longitudinal axis. A twist angle of the second lever about the second longitudinal axis is related to a rotation speed of the work implement about the at least one axis of rotation. A plurality of operator control devices are disposed on the first and second levers.

Abstract: Disclosed herein are various embodiments of methods, systems, and apparatus for increasing packet generation in a digital communication system. In one exemplary method embodiment, multiple input signals are interpolated, shifted, and aggregated into a composite signal for transmission over a network.

Abstract: A method and system provides a way to achieve very high data rate expanded bandwidth (wide band) WLAN operations reusing existing single channel radio designs. The system provides a dual-channel form of operation for greater flexibility and performance across multiple platforms. Further, the system provides adaptive anti-aliasing techniques for eliminating aliasing due to adjacent channel waveform effects. These techniques mesh with existing systems cleanly.

Abstract: An adaptive frequency equalization system providing an equalizer that has programmable taps that adjusts magnitude and phase of symbol information of a received signal and that provides equalized symbol information. The system includes a hard decision circuit that selects ideal symbol values using the equalized symbol information. A frequency response circuit determines frequency response update values using the ideal symbol values and the received signal. An adjust circuit updates stored frequency response information using the frequency response update values, and also updates the programmable taps of the equalizer using the stored frequency response information.

Abstract: A numerically controlled oscillator wherein only one quadrant of a sinusoidially shaped wave is stored in a read-only-memory and the address of the read-only-memory is generated so that the entire numerically controlled oscillator and the read-only memory are contained on a single semiconductor chip. The data required to reproduce the quadrant is stored in a decomposed format so as to reduce the size of the read-only-memory.
