Abstract: A telecommunication system having a cellular mobile telephone system in which calls from cellular telephones are routed through a mobile service switching center exchange. Users of the system, having control of respective groups of mobile telephone are able via user terminals to access respective databases in a signalling processor and to place in the data base information about call parameters, such as call restrictions, for ones of the telephone of that user controlled group. When a call is made from any mobile telephone, the call signal is decoded at the relevant exchange and a determination is made as to whether the call originates from a mobile telephone which is a member of a controlled group. If so, the related database in the controller is accessed and the call is controlled in accordance with the appropriate call parameter, on the basis of the information in the related database.

Abstract: An inflator assembly inflates a vehicle occupant restraint. The inflator assembly includes a container which stores gas under pressure. A body of an ignitable pyrotechnic material is disposed within the container. An igniter assembly is actuatable in response to being struck to ignite the body of pyrotechnic material. An actuator assembly is provided to release the stored gas from the container and to actuate the igniter assembly. The actuator assembly includes a pyrotechnic which moves an actuator member to rupture a portion of the container and to strike the igniter assembly. Upon actuation of the igniter assembly, the pyrotechnic material is ignited and begins to burn. During initial burning of the pyrotechnic material, an orifice plate restricts a flow of combustion products to promote burning of the pyrotechic material.

Abstract: An instrument for determining the variation in tension of a ligament graft extending between first and second proposed fixation sites positioned on first and second articulated bones, respectively, comprises a yoke which carries a device for securing the yoke to one of the first and second bones. A yoke plate is rotatably carried by the yoke. A main housing is adapted for connection to the yoke plate. A sled is slidably carried by the main housing. The sled is adapted for connection to the ligament graft. A mechanism is provided for adjusting the position of the sled relative to the housing so as to place a desired degree of tension on the ligament graft. A transducer is associated with the mechanism for adjusting for determining changes in tension, if any, from the desired degree of tension as the first and second bones are moved relative to one another.
