Patent CA-2245241-C (CA)
Title: A method for performing a soft handoff
Inventor: KUMAR SARATH
IPC: H04W36/18
Filed: 1998-08-18
Granted: 2002-10-15
Abstract: The present invention increases the success rate of soft handoffs by enhancing the ability of a mobile-telephone to receive a handoff direction message that identifies the traffic channel being assigned to enable a candidate base station to communicate with the mobile-telephone. Specifically, the aforementioned ability of the mobile-telephone is enhanced by using the candidate base station to transmit the handoff direction message on a communication channel belonging to the candidate base station and being listened to by the mobile-telehone. In situations where signals transmitted from active set base stations have a low signal-to-noise ratio at the mobile-telephone, signals transmitted from the candidate base station may have a higher signal-to-noise ratio at the mobile-telephone. In these situations, the transmission of the HD messages from the candidate base station increases the likelihood that a copy of the handoff direction message will be successfully received by the mobile-telephone, therebyenhancing the success rate of soft handoffs.

Granted: 2005-07-12
Abstract: Method and apparatus for providing centralized power control in a communication system, in which each base station (14, 16, 18, 20) in the system operates to control both the forward link and the reverse link power. A radio link manager (22) provides a common threshold for determining the proper power level of the reverse link signal at each base station (14, 16, 18, 20). The radio link manager (22) also provides a ratio of the forward link signal strength to a pilot signal strength to control forward link power control. The radio link manager (22) provides the threshold and ratio uniformly to all base stations (14, 16, 18, 20) to provide a uniform operating point for all base stations (14, 16, 18, 20) in the system, thus, increasing capacity. The same centralized power control is easily expanded to provide a mechanism for intersystem soft handoff.

Abstract: In a seismic data acquisition system that uses a vibratory source an actual groundforce signal is recorded. This groundforce signal includes, in addition to a reference sweep signal, noise including harmonic distortion. This recorded groundforce signal is used to derive a filter that is used for filtering seismic data that has been generated by the source and reflected by subsurface reflectors to suitable detectors at the surface. The filter is derived by dividing, in the frequency domain, a short duration wavelet by the time derivative of the ground force signal.

Patent CA-2283046-C (CA)
Title: Methodology for emulation of multi-threaded processes in a single-threaded operating system
Inventor: FORSMAN STEPHANIE M
IPC: G06F9/48
Filed: 1999-09-23
Granted: 2003-07-15
Abstract: To emulate multi-threaded processing in an operating system supporting only single-threaded processes and single-level interrupts, the processor timer is started with a selected time-out period during execution of a master code thread. Processing of the master code thread proceeds until the timer interrupt, at which time the operating system timer interrupt service routine (ISR) transfers execution control to a slave code thread or slave code thread component. The slave code thread or component is executed in its entirety, at which time the timer is reset and execution control is returned to the master code thread, where processing resumes at the point during which the timer interrupt was asserted. To minimize disruption of the master code thread execution, a maximum latency should be enforced on the slave code thread, which may be accomplished by breaking the slave code thread into multiple components. The timer ISR maintains an index of the predetermined starting points within the slave code thread(s) with a pointer identifying the next slave code thread component to be selected when the timer interrupt is asserted. Processing thus alternates between the master code thread and the slave code thread or components, with different slave code thread components being selected in round-robin fashion. The duty cycle between the master code thread and the slave code thread or components may be varied by selection of the time-out period and the maximum latency allowed to slave code thread processing.

Abstract: A sterilizer including a sterilization chamber for receiving articles to be sterilized and a door supported on a horizontal pivot at an access opening of the sterilizer chamber. The door includes a seal plate and a resilient seal member supported on the seal plate wherein the seal member includes an annular lip extending transversely to the plane of the seal plate. The lip extends into the sterilizer chamber wherein pressure within the chamber exerts a force biasing an opposing surface of the lip into engagement with an inner surface of the chamber. The sterilizer door is movable between a fully closed and a fully open position and includes a mechanism for holding the door in a partially open position. In the partially open position, the lip extends into contact with a surface of the sterilizer chamber to thereby form a bridge between the door and chamber and prevent condensation from dripping down away from the chamber and door. A controller is provided for controlling sterilization cycles and actuates the door to move to the partially open position at the end of a sterilization cycle. In addition, a pressure actuated lock is provided for preventing the door from opening when the chamber is pressurized. The controller further automatically controls purging of air from the sterilizer chamber during a steam generation mode of a sterilization cycle wherein the controller senses the temperature and pressure during the sterilization cycle, and in response thereto, opens a purge valve to release air when the conditions within the sterilizer deviate by a predetermined amount from preset conditions monitored by the controller.

Title: Method of handling short message service acknowledgement messages between cooperating mobile switching centers in a radio telecommunications network
Inventor: JOONG DONALD
IPC: H04W36/12
Filed: 1998-09-29
Granted: 2010-06-29
Abstract: A method of handling SMS messages in a radio telecommunications network when an originating mobile station-based Short Message Entity (MS-SME) (31) sends an SMS origination message (35) while operating in a first Mobile Switching Center (MSC) (32) and then moves into a second MSC (33) before the MS-SME  receives an SMS acknowledgement message (43). The method begins by including an R_Transaction ID parameter in the SMS origination message (35) sent over the Digital Traffic Channel (DTC) from the originating MS-SME to the first MSC. If the MS-SME moved back to an anchor MSC (33), an SMS_Transaction ID  (SMSTID) parameter (37) is included in an ANSI-41 SMS Delivery Backward (SMDBACK) Invoke message (36) sent from the first MSC to the anchor MSC. The SMSTID parameter utilizes information from the R_Transaction ID parameter to enable the MS-SME to correlate an SMS acknowledgement message with the SME  origination message. If the MS-SME moved to a new serving MSC (51), the SMSTID  parameter is placed in an SMS Delivery Point-to-Point Acknowledgement (SMDPPACK) Invoke message (57), and sent from the anchor MSC (33) to the new serving MSC (57). The information in the SMSTID parameter is used by the second MSC to send an SMS acknowledgement message (60) to the originating MS-SME.
