Title: Methods and apparatus for retiming and realignment of sts-1 signals into sts-3 type signal
Inventor: PARRUCK BIDYUT
IPC: G06F5/12
Filed: 1993-03-09
Granted: 2001-10-30
Abstract: The SPE of an incoming STS-3 type signal is demultiplexed into three STS-1 payloads and fed to three FIFOs (45-1, 45-2, 45-3), and a byte which is synchronous with the TOH is tracked through the three FIFOs (45-1, 45-2, 45-3) to provide an indica-tion of the FIFO depth. A frame count is also kept to track the number of frames since a last pointer movement. Stuffs or destuffs are generated based on the FIFO depth as well as based on the frame count, with a stuff or destuff generated as quickly as four frames from a previous pointer movement if the FIFO is close to full or close to empty, and less quickly (e.g., at thirty-two frames from a previous pointer movement) if the FIFO is only starting to empty or to fill. Where the STS-3 type signal is an STS-3C sig-nal, the decision on whether to stuff or destuff is made with reference to all three depth measurement circuits (48-1, 48.2, 48-3) as all the STS-1 payloads must be stuffed or destuffed together.

Abstract: A  spread  spectrum  code  pulse  position  modulated communication system is disclosed.  The communication system includes a spread spectrum code pulse position modulated receiver  that  compensates  for  the  delay  spread of  a transmission medium, such as a wireless radio channel of a local  area  network.    Delay  spread  may  cause  signal components of one transmitted spread spectrum codeword to spill over into chip positions of adjacent symbols, causing intersymbol  interference,  or  into  chip  positions  on quadrature channels of a given symbol interval, such as in a QPSK implementation, causing interchip interference.  The disclosed receiver decodes a transmitted spread spectrum code pulse position modulated signal in the presence of such delay spread,  utilizing a tentative symbol estimator to sample the matched filter data.   The tentative  symbol estimator will assign a weight to each potential symbol value, taking into account the cross-rail or bias influence caused by the residual coupling between the signals on quadrature  channels  for  a  given  symbol  duration.    In addition,  the disclosed receiver includes a mode sifter which evaluates the weighted values for each symbol estimate and assigns final estimates to each symbol value, taking into account the influence of codewords transmitted during one or more successive symbol intervals on one another.

Abstract: This is a system for determining a position of a probe (302) relative to as object such as a head of a body of a patient. The head includes a surface such as a forehead having a contour. Cross-sectional images of the head are scanned and stored as a function of the forehead contour. If the forehead contour does not appear in the scan images, then the position of the forehead contour relative to the scan images is determined with an optical scanner (380) and ring (590). During surgery, the optical scanner (380) also determines the position of the tip of the forehead relative to the ring (590). An easy (300) for receiving radiation emitted from the probe and from the ring generates signals indicating the position of the tip (301) of the probe (302) relative to the ring (590). A stereo-tactic imaging system (324) generates and displays an image of the head corresponding to the measured position of the tip (301) of the probe (302).
