Patent CA-2192487-A1 (CA)
Title: Transmitting and receiving long messages in a wireless one-way communication system while reserving selected slots for short messages
Inventor: GASKILL GAROLD B
IPC: H04W52/02
Filed: 1995-07-14
Abstract: A receiver operates in both a first polling protocol and in a selectable data acquisition protocol to both conserve power while quickly read long messages in wireless one-way communication systems. The receiver first polls data transmissions at a relatively slow periodic rate to identify messages. When the receiver identifies a corresponding address in the data transmission, a format packet directs the receiver to acquire data using a second data acquisition protocol independent of the polling protocol. The data acquisition protocol enables long messages to be communicated in a fast, highly reliable manner. After the long message is successfully transmitted, the receiver automatically reverts back into a polling protocol to conserve power.

Title: Wireless handset paging utilizing connection endpoint service identifiers
Inventor: COLEMAN FORREST L
IPC: H04W68/02
Filed: 1997-04-23
Abstract: PCS switching system processes the movement of a wireless set from one paging zone to another paging zone or from one base station to another base station at the lowest software layer in the PCS switching system thereby reducing the amount of processing required of the PCS switching system. Each base station is interconnected to the wireless switching network by communication links. When a wireless set registers on the wireless switching network via a base station, a physical object is established that will control the physical protocol used to communicate with the wireless set. In addition, a software object is established that will control the first layer of software protocol to communicate with the wireless set. When the wireless set moves to a new base station that interconnects to the wireless switching network, it initiates contact with the new base. This initialization causes a new physical object to be established. The software object is also updated to use the new physical object instead of the one established on registration. Thus, information for the wireless set is routed to the new base station via the new physical object; and hence, communication with the wireless set is maintained without going above thefirst software control layer.

Title: Method and apparatus for hybrid element casing packer for cased-hole applications
Inventor: SOLARI MARK C
IPC: E21B33/1295
Filed: 1997-12-12
Abstract: The present invention is directed to a new and improved wellbore packing device for use in isolating zones within a subterranean wellbore and to methods for applying the packing device in a cased-hole application. The present invention is directed to a new and improved inflatable or external casing packer (ECP) for use in cased wellbores. A hybrid inflatable packing element design in an ECP is presented, having in a single-unit, anchoring and sealing sections for application in cased wellbores using a phase change inflation medium such as cement or epoxy ar the like. The present invention overcomes limitations of existing prior art ECP's since these prior art ECP's are not capable of providing both sealing and anchoring packing elements in a single unitized design in size and access restricted wellbores. The inflatable elements comprise a sealing section that uses a noncontinuously reinforced elastomeric element with anti-extrusion ribs at its ends. When filled with the inflation medium, a frictional, radial force sealingly engages the elastomeric element with casing wall. An anchoring section is also provided that uses a continuously ribbed elastomeric bladder element. The steel ribs on the surface of the elastomeric element engage in metal-to-metal contact with the casing wall as the inflation medium exerts a Frictional, radial force. Any trapped. wellbore fluid between the sections escapes via the pathway between the ribs. A method for use of the hybrid ECP is also disclosed. More specifically, a method for use of the hybrid inflatable packer is a cased hole environment with a phase change inflation media is presented.
