20080271239MULTI-FUNCTION SINK WITH CENTRIFUGAL FOOD DRYER AND DRAIN - A multi-function sink includes a basin, a motor and a colander. Advantageously, the basin is supported by a frame, which frame is sized and shaped to fit into a corresponding aperture in a counter. Wet food is placed into the colander and the colander is placed into the basin. A sink-based coupler mates with a colander-based coupler. The user activates the motor, thereby causing the motor to rotate the colander and centrifugally dry the food. The building-in of the multi-function sink into a counter provides advantages over stand-alone centrifugal food driers in that the location of the food drier is readily known and, in those embodiments that include a faucet assembly, a ready supply of water is available for washing the food before centrifugally drying the food. Further advantageously, when the colander is removed, the multi-function sink may be used as a simple basin having a drain.11-06-2008

20090034659PILOT SYMBOL ASSISTED MODULATION SIGNAL PROCESSING SYSTEMS AND METHODS - Pilot symbol assisted modulation (PSAM) techniques for Rayleigh and Rician fading channels are derived. Previous techniques implement PSAM signal detectors as an ad-hoc design, using pilot symbols to first estimate channel gain, and then using channel gain estimates in a conventional coherent detector to make data decisions. Although this structure may be effective for binary phase shift keying in Rayleigh fading, it is suboptimal for Rician fading and for 16-ary quadrature amplitude modulation in Rayleigh fading. According to techniques disclosed herein, a PSAM signal detector jointly processes pilot symbols and data symbols. The performance of signal detectors according to embodiments of the invention is analyzed and compared with that of conventional detectors. Numerical results are presented to show that the performance gain of a proposed new PSAM signal detector over conventional PSAM detectors can be as much as 2 or 3 dB for Rician fading in some cases.02-05-2009

A nonlinear signal processing unit contains one or multiple subunits, and each subunit consists of a nonlinear device and a filter. The nonlinear devices can be any devices that can shift signal, noise, and interference spectra in a nonlinear fashion, and include but are not limited to square law devices and Teager-Kaiser operators. By applying the nonlinear signal processing unit on the received UWB signal, a major part of the energy of noise and narrowband interferences is shifted to specific frequency ranges and then removed by the appropriate filter(s) in the nonlinear signal processing unit. Thus, the signal-to-noise-plus-interference ratio (SNIR) of the received UWB signal can be improved.03-07-2013
