Abstract: An apparatus and method for producing an oriented plastic strap having a predetermined desired thickness and flatness characteristics for use in connection with the strapping of packages or the like, is disclosed. A sheet workpiece is conducted into a nip defined between a pair of opposed milling and stretching rollers wherein one of the rollers is rotated at a lineal surface velocity which is greater than the lineal surface velocity of the other roller and the rollers are rotated in opposite directions. One of the rollers effectively brakes or retards one of the surfaces of the sheet workpiece while the other one of the rollers effectively accelerates the other one of the surfaces of the sheet workpiece as the workpiece passes through the nip defined between the rollers whereby the workpiece is simultaneously milled and stretched. The workpiece is heated along its side portions disposed inwardly from the side edge portions so as to eliminate concavities and bump transitional points which normally tend to form at and within the vicinity of the side portions and in addition, the side edge portions of the sheet workpiece are also heated so as to cooperate with the heated, axially inward side portions so as to advantageously control the degree of flatness of the sheet workpiece across the width thereof after the same has been milled and stretched.

Title: Joint detector for multiple coded digital signals
Inventor: MOHER MICHAEL L
IPC: H04L5/02
Filed: 1997-04-01
Granted: 2004-06-22
Abstract: A method for the joint detection of multiple coded digital signals that share the same transmission medium in a manner that causes mutual interference. The method is comprised of two steps that are applied to preliminary estimates of each digital signal, one or more times. The first step is to obtain reliability estimates for each data element of each digital signal by combining the preliminary estimates, a statistical model for the interference, and any a priori information regarding the data elements. The second step is to revise these reliability estimates for each digital signal based on the forward error correction code used for that digital signal. When the steps are repeated, the revised reliability estimates from the second step are used as a priori information for the first step.

Granted: 1999-11-23
Abstract: A method wherein the scan rate of an active emitter is simultaneously estimated by a tracking receiver and a radar system and are then compared to correlate tracks generated by the tracking receiver and the radar system. The output produced by the present method provides for data that is more accurately indicative of the locations and identifications of emitters tracked by the tracking receiver and the radar system. More specifically, the method comprises the following steps. An active emitter having a scanning antenna is simultaneously tracked using a tracking receiver and a radar system. The location of the emitter is estimated using the tracking receiver by processing measurements of the electromagnetic signals generated by the emitter. The scan rate of the emitter is estimated using the tracking receiver by detecting strobing of the main lobe of the signals generated the emitter. The scan rate of the emitter is estimated using the radar system. Finally, the respective estimated scan rates are correlated to improve the accuracy of the estimated location and identification of the emitter.
