Abstract: A system and method for detecting a synchronization (sync) signal in a communication signal are disclosed. A received communication signal is stored in a memory and portions thereof are read from the memory and monitored to detect the sync signal. When a detected sync signal is determined to be invalid, previously read portions of the received communication signal, preferably beginning at a portion of the received signal immediately after a start of the detected sync signal, are again read and monitored to detect the sync signal. Such reading and monitoring of previously read portions of a received signal provide for recovery from so-called false triggering based on invalid sync signals.

Title: Mig gun nozzle with self centering, quick release screw and reduced cross sectional area at the front
Inventor: ALTEKRUSE KENNETH C
IPC: B23K9/173
Filed: 2002-01-04
Abstract: A MIG welding gun has a diffuser with an external thread and a frusto-conical back ramp. A nozzle assembly includes an insert with a back ramp and a thread that mates with the diffuser thread. The threads of the diffuser and insert have respective ramps that mate. A single turn of the nozzle assembly on the diffuser causes simultaneous engagement of the insert and diffuser back ramps and of the insert and diffuser thread ramps.      Such engagement centers the nozzle to be concentric with the diffuser and also produces a wedging action that retains the nozzle assembly on the diffuser until a relatively substantial reverse torque ie applied to the nozzle assembly. The nozzle front end has a narrow annulus, which reduces the amount of radiant heat from the welding are that reaches the nozzle.

Patent CA-2374556-A1 (CA)
Inventor: DAVIES ELWYN B
IPC: H04L12/56
Filed: 2002-03-05
Abstract: Consider a path between two nodes in a communications network. This path (which may be physical or logical) has a finite bandwidth or size. For particular types of communications network, such paths are manufactured and provided with standard bandwidths or sizes. When the amount of traffic between the two nodes along a single path exceeds the standard bandwidth, it is necessary to provide one or more additional paths between the two nodes. It is then necessary to distribute or allocate incoming traffic between the multiple possible paths and to do this in a manner which preserves the order of packets within particular flows of traffic. This is achieved by using flow labels of packets and inputting those flow labels into a hash function. The flow labels are preferably chosen pseudo randomly, or randomly, as well as uniformly from a specified range of values. The hash function results are bucketed and one bucket associated with each possible path. Any packet whose hash value falls into the hash bucket for a path is dispatched along that path. All the packets within a particular flow are given the same flow label and in this way, the order of packets within a particular flow is preserved.

Title: Method and apparatus for detecting zero rate frames in a communications system
Inventor: CHEN TAO
IPC: H04B7/005
Filed: 2000-08-31
Abstract: Techniques for detecting zero rate frames in a received data transmission. A  modulated signal is received and demodulated in accordance with a particular  demodulation format to generate demodulated symbols. The demodulated symbols  are partitioned into a number of received frames. For each received frame, a  quality metric is computed and compared against a threshold value. The threshold value is selected based, in part, on the quality metrics of receiv ed frames. Based on the comparison result, the received frame is indicated as being either transmitted and received in error (i.e., erased or bad) or not transmitted at all (i.e., zero rate or empty). The quality metric can relate  to an energy of a received frame, a distance between a received frame and a codeword corresponding to the received frame, or other metrics. The threshol d value can be selected based on the quality metrics computed for decoded fram es or received frames identified as good, and can be dynamically adjusted based  on current information available at the receiver. The method is advantageous ly used in a CDMA communications system (100).

Inventor: FERNANDO XAVIER NAVAJOTHY
IPC: H04B10/2575
Filed: 2002-04-26
Abstract: A Fiber-wireless uplink consists of a wireless channel followed by a radio-over-fiber (ROF) link. Typically, nonlinear distortion of the ROF link is the major concern when the radio frequency is only a few GHz. This especially severe in the uplink, because of the multipath fading of the wireless channel. A Hammerstein type decision feedback equalizer is described for the fiber wireless uplink, that compensates for nonlinear distortion of the ROF link as well as linear dispersion of the wireless channel. Since the linear and nonlinear parts of the receiver are separated, tracking the fast changing wireless channel is virtually independent of compensating for the relatively static nonlinearity. Analytical results show that the receiver provides excellent compensation with notably less complexity.
