Abstract: Apparatus and method for forming a metal bellows includes a dispenser containing a supply of ring shaped metal foil sheets feeding a jig situated adjacent to the dispenser that coaxially positions the metal rings. A mandrel applies a pressure normal to the surface of the foil sheets, and a laser is focused on a locus of points a top surface of the top pair of the rings, the locus of points being positioned adjacent to one of the outer perimeters and inner edges of the rings. A regulator coupled to the laser forms energy pulses suitable to weld the pair of metal rings proximal to the laser together, the energy pulse being insufficient to penetrate the second metal ring of the pair.

Abstract: A system for providing a dynamic multi-mode service acquisition capability to a subscriber station is provided. The subscriber station is capable of operating in two or more modes of operation. A time to scan condition is indicated while the subscriber station is operating in a current mode of operation having active and inactive states. Responsive thereto, the system stores state information for the current mode of operation, and attempts at least a partial acquisition of communications services in accordance with another mode of operation. The at least partial acquisition attempt is scheduled to be initiated while the subscriber station is operating in the inactive state in the current mode of operation, and completed before the subscriber station transitions back to the active state in the current mode of operation. If the acquisition attempt is successful, the subscriber station transitions to the new mode of operation, maintaining appropriate registration.

Abstract: A hemming and in-situ laser welding method and apparatus for hemming peripheral flanges of an outer steel panel over peripheral edges of an inner steel panel and laser welding the resulting hemmed joints. A lower die supports an outer metal panel in a position to be hemmed over an edge of an inner panel.

Abstract: A method and apparatus for acquiring an emergency service from one or more candidate mobile radio communication systems. An attempt is made by the mobile radio unit to acquire normal non-emergency service. If the attempt of acquiring normal non-emergency services fails and the user needs to originate an emergency call, an emergency scan list containing one or more candidate mobile radio communication systems is scanned, and an attempt is made to acquire emergency service from one of these systems. The emergency scan list is different from the normal preferred roaming list stored in the mobile radio unit. Next, the invention originates an emergency call in accordance with the service acquired from the emergency scan list.

Abstract: A method and apparatus for connecting a metal lid to a metal body of a container to seal any product held by the container. The container is formed from a generally cylindrical metal body having an upper edge and a metal lid having a peripheral edge. The metal lid is held in position on the metal body so that the upper edge portion of the metal body and the peripheral edge of the metal lid form a contiguous junction. A beam of laser energy is directed toward the contiguous junction for sufficient time to hermetically seal the lid to the body. A single roll-formed lip provides a smooth finish to the combined body and lid. The lid includes a circumferentially continuous recess surrounding a central planar portion of the lid. The recess is located adjacent the peripheral edge while the peripheral edge is situated at or below the plane defined by the central planar portion, thereby reducing the material required to form a sealed container of any given volume.

Abstract: A method and apparatus for selecting a communication system in accordance with the geographic region in which the subscriber station is located is described. Upon successful acquisition, a system determination processor examines the received system identification information and compares it with system identification information stored in a universal system table to determine the geographical region of the identified communication system. The system determination processor then determines whether the acquired system is the most desirable system for use in the geographical region. If it is the most desirable system for use in the geographical region, the system determination processor selects the acquired system for providing service. If it is not the most desirable system for use in the geographical region, the subscriber station attempts to acquire a more desirable system using information from the universal system table.

Abstract: A method of processing uncorrelated data from at least one multiple-contact tracking system is provided. The method identifies which of a plurality of contacts being tracked that the uncorrelated data is most likely to be associated with. By combining correlation with reassessment processing, correlation errors can be reduced or minimized. A threshold test (e.g., bearing test) is used to screen or coarsely filter the data while a comparison scoring test is used associate the uncorrelated data with one of the contacts. The same threshold test and comparison scoring test are used for both correlation and reassessment processing.

If it is the most desirable system for use in the geographical region, the subscriber station provides service using the acquired system. If it is not the most desirable system for use in the geographical region, the subscriber station attempts to acquire a more desirable system.

Abstract: A method of data fusion determines a best-estimate solution to a moving cact using a plurality of trackers that provide bearing-to-contact data and range-to-contact data. An averaging function is applied to the bearing-to-contact data to determine weighted-average bearing data associated with each tracker. The same averaging function is also applied to the range-to-contact data to determine weighted-average range data. A computed solution to the moving contact is generated using the weighted-average range data and the weighted average bearing data from the one tracker having the lowest standard deviation. A root mean square (RMS) error in terms of bearing is then determined for the computed solution and each of a plurality of independently generated solutions using bearing-to-contact data from the one tracker having the lowest standard deviation. One of the computed solution or the independently generated solutions that produces the lowest RMS error is considered to be the best-estimate solution.

Abstract: The wireless communication device receives a neighbor list message from a first base station. The neighbor list message includes a respective base station configuration parameter for each of a plurality of base stations. In response to the neighbor list message, the wireless communication device constructs a neighbor list table, including one record for each of the plurality of base stations, with each record including their respective base station configuration parameter. After handing off to a second base station, the wireless communication device replaces the record for the second base station with a corresponding record for the first base station. The wireless communication device then may change the respective base station configuration parameter for at least one of the records of the plurality of base stations in the neighbor list table to match the base station configuration parameter of the second base station.

Abstract: A novel and improved method and apparatus for signal acquisition in a wireless telecommunication system having large transmission delay uncertainty is described. A terminal first acquires the forward link signal from a hub and extracts timing information from that forward link signal. Using the timing information the terminal estimates the time at which a next search window takes place during an access slot, and the time and pseudorandom code state necessary to transmit an access probe so as to arrive at during the search window assuming the terminal is located a maximum distance from the hub. The terminal proceeds to transmit additional access probes at times occurring one access slot period plus a delta time interval after the previous transmission. The delta time interval has a duration less than that of a search window associated with each access slot.
