Abstract: Disclosed is a pressure sensor, for example for a domestic central heating boiler, comprising a rolling diaphgram (15) that adjusts its position in dependence upon the fluid pressure admitted through a pressure port (5). The diaphgram acts against an actuator (7) which adjusts the position of a wiper (20) of a thick film potentiometer, to provide an output voltage in dependence on the admitted fluid pressure. The potentiometer may be calibrated at the factory by rotating an adjustment cap (11) of the actuator (7), which has claw-like projections in engagement with outward projections of part-helical form on a body part (8) of the actuator. There is a one-to-one axial position relationship between the actuator (7) and the wiper (20).

Patent CA-2328884-A1 (CA)
Inventor: FOTI GEORGE
IPC: H04M3/42
Filed: 1999-03-26
Abstract: A method of recovering from a restart procedure in a mobile switching center (MSC) in a radio telecommunications network having a home location register (HLR) that maintains subscriber profiles and a MSC that maintains temporary subscriber records associated with the subscriber profiles in the HLR. The MSC maintains the temporary subscriber records in the MSC during the restart procedure, and flags each temporary subscriber record in the MSC that went through the restart. The HLR flags each subscriber profile in the HLR that fails an attempt to update an associated temporary subscriber record in the MSC during the restart procedure. When an access attempt is received in the MSC that requires use of a temporary subscriber record that is flagged, the MSC requests the HLR to send any changes to the flagged temporary subscriber record. The HLR then determines whether the subscriber profile associated with the flagged temporary subscriber record in the MSC is flagged in the HLR. If the subscriber profile is not flagged, the HLR sends a message to the MSC indicating that there are no changes to the flagged temporary subscriber record. However, if the subscriber profile in the HLR is flagged, the HLR sends to the MSC, the changes stored in the flagged profile which then update the flagged temporary subscriber record in the MSC. The flagged subscriber profile and the flagged temporary record are then reset.
