The source code file is compiled to create an individual executable rule file. A rule selection repository contains identification of groups of selected executable rule files. The invention determines the category of the customer order and reads, from the rule selection repository, a group of executable rule files that correspond to the identified category of the customer order. The selected executable rule files are executed to check the conformance of the customer order. Execution results are stored in a status repository for subsequent retrieval and analysis.	10-09-2008

20080271239	MULTI-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

20090034659	PILOT 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
