Title: Pn sequence generator with bidirectional shift register and eulerian-graph feedback circuit
Inventor: SHIMADA MICHIO
IPC: H03K3/84
Filed: 1998-05-20
Abstract: A pseudorandom number sequence generator comprises a bidirectional shift register arranged to be loaded with a multi-bit sequence. The shift register is responsive to an ith clock pulse and an ith direction control bit for shifting the multi-bit sequence in one of two directions, delivering an ith output bit and receiving an ith input bit. The multi-bit sequence successively defines one of nodes of an Eulerian graph connected by branches. A feedback circuit is connected to the shift register for converting a set of input data to a set of output data. The input data comprises a multi-bit sequence stored in the shift register in response to an (i+ 1)th clock pulse, the ith output bit and the ith direction control bit and the output data comprises an (i + 1)th input bit and an (i + 1)th direction control bit. The output data is supplied to the shift register so that multi-bit sequences produced by the shift register move around the graph following every branch exactly once, and outputting the (i + 1)th input bit to form a pseudorandom number sequence.

Inventor: WERB JAY
IPC: G06K17/00
Filed: 1997-10-17
Abstract: System for tracking mobile tags. Cell controllers with multiple antenna modules generate a carrier signal which is received by the tags. Tags shift the frequency of the carrier signal, modulate an identification code onto it, and transmit the resulting tag signal at randomized intervals. The antennas receive and process the response, and determine the presence of the tags by proximity and triangulation. Distance of a tag from an antenna is calculated by measuring the round trip signal time. The cell controllers send data from the antenna to a host computer. The host computer collects the data and resolves them into positional estimates. Data are archived in a data warehouse, such as an SQL Server.
