Patent CA-2392237-A1 (CA)
Title: Batch sheet feeding
Inventor: COOK EDWARD J
IPC: B65H29/14
Filed: 2002-06-28
Abstract: A batch sheet feeder has an upstream first conveyor section arranged to convey sheets singly in a downstream direction to a downstream second conveyor section. The second conveyor section has an upper second conveying section and a lower second conveying section forming a gap therebetween. The gap is largest at an upstream end of the second conveyor section and diminishes in size toward a downstream end of the second conveyor section. A gate positioned proximate the downstream end of the second conveyor section selectively blocks sheets fed along the second conveyor section. In another embodiment, the sheet feeder has a sheet conveyor, sheet sensor, and visual attribute sensor. The visual attribute sensor has a field of view covering an area of the conveyor at a certain downstream location so as to sense an area of any sheet on the conveyor at this downstream location. The visual attribute sensor can compare a sensed area of a sheet at the downstream location with a stored visual attribute. In this way, where the sheets of a batch are different, the visual attribute sensor can be used to verify that a sheet of a batch has visual characteristics matching those of the expected sheet at that ordinal position in the batch.  This assists in ensuring a batch is not faulty. In a related method of verifying batches of sheets, for each sheet at a given ordinal position in each batch a visual attribute measure for at least an area of the sheet is obtained. A comparison is made of the visual attribute measure with a stored visual attribute measure. Each batch is selectively verified based on this comparison.

Title: Frequency translator using a cordic phase rotator
Inventor: SULLIVAN MARK C
IPC: H04L27/12
Filed: 2001-08-09
Abstract: A frequency translator (201) uses a CORDIC phase rotator (202) coupled to a phase accumulator (102) to translate an input signal in frequency. The CORDIC  phase rotator performs required phase angle rotations of input vectors using only shift and add operations. Thus, the frequency translator can be readily implemented in hardware. Higher precision arithmetic is used in the CORDIC  phase rotator operations than the input contain. To avoid truncation error at the output of the CORDIC phase rotator, stochastic rounding is employed. A  dither signal is added to avoid errors due to nonlinear operation of D/A  converters, where D/A conversion of the frequency translated signal is required.
