Title: Load monitoring and management in a cdma wireless communication system
Inventor: SOLIMAN SAMIR S
IPC: H04B7/005
Filed: 1997-07-29
Abstract: A system and method for monitoring and managing the loading conditions in a CDMA wireless communication system (100). The system comprises a load monitoring device (102) such as a CDMA mobile station (104) connected to a data logging and processing device (106) such as a diagnostic monitor. The monitoring device (102) is placed within the service area of a base station (112). The monitoring device (102) periodically initiates a call, is assigned to a traffic channel normally, and logs a power control parameter such as mobile station transmit power or the number of closed-loop power control commands received per unit time. From this information, the load monitoring device (102) can infer the real-time traffic loading conditions of the base station (112). If the loading of the system exceeds a predetermined threshold, an alarm may be sent to the system management center (114) in order to take some action to limit additional loading on the base station (112).

Patent CA-2269266-A1 (CA)
Title: A liquefaction handpiece
Inventor: SUSSMAN GLENN
IPC: A61B17/32
Filed: 1999-04-19
Abstract: A surgical handpiece having at least two lumens mounted to a body. At least one lumen is used for aspiration and at least one other lumen is used to inject heated surgical fluid for liquefying a cataractous lens. A portion of the second lumen is enlarged to form a pumping chamber. The pumping chamber works by boiling a small volume of the surgical fluid. As the fluid boils, it expands rapidly, thereby propelling the liquid downstream of the pumping chamber out of the second lumen. The pumping chamber may use a pair of electrodes, and one of the electrodes may contain a countersink.

Filed: 1998-04-03
Abstract: According to the inventive method for controlling an automatic cleaning device used for cleaning the surface of a window, the cleaning head is first advanced onto the window surface, approximately in the center or close to the edge, by means of a powered control system. This starting position is determined using the basic information for the building concerned provided in the plans of the building. The cleaning head is subsequently moved over the window surface as far as the window frame in direction X or Z, in a first seek-edges-mode, then moved along the window frame into the corner of the window, where the actual cleaning process starts. The frame of the cleaning head can be moved elastically in relation to the fixed structure so that the control device is able to determine whether the cleaning head is in contact with a window edge.  In the case of windows without frames, a sensor can be provided, the signal of the sensor being detected by the control device.

Title: System and method of delivering collect calls in a radio telecommunications network
Inventor: FOTI GEORGE
IPC: H04M15/08
Filed: 1998-09-17
Abstract: In a radio telecommunications network, a system and method of informing a called mobile station (14) operating in a visited mobile switching center (V-MSC)(13) that an incoming call is a collect call prior to delivering the incoming call to the mobile station. The system obtains in an originating mobile switching center (O-MSC)(11), a collect call prefix (16) from a calling party and determines from the collect call prefix that the incoming call is a collect call. A collect call indication (CCI)(17) is generated and sent along with the calling number to the V-MSC in a Location Request (LocReq) Invoke message (19) and a Routing Request (RoutReq) Invoke message (21), thereby notifying the V-MSC that there is an incoming call for the mobile station and the incoming call is a collect call. The V-MSC (13) sets a collect call flag (23) to ON, stores the calling number in a subscriber record (22) in the V-MSC, and determines whether the mobile station is a digital mobile station. If so, a Short Message Service (SMS) message (34) including the calling number is sent to the mobile station informing the subscriber that the incoming call is about to be delivered and the incoming call is a collect call. If the mobile station is a dual-capable mobile station, a distinctive ringing signal (38) is sent to the mobile station. The incoming call is then delivered to the mobile station, and the subscriber may choose to answer or not. The collect call flag (23) is then reset to OFF in the subscriber record in the V-MSC.

Title: A method for strong partitioning of a multi-processor vme backplane bus
Inventor: YOUNIS MOHAMED F
IPC: G06F15/17
Filed: 1998-09-29
Abstract: A method for strong partitioning of multi-processor applications that maintains fault containment on the VMEbus is presented. The method implements a message passing mechanism to increase fault tolerance and localize and contain detected faults on any one card connected to a VMEbus. Software implementation supports message-based inter-module communications using the available features provided by the VME cards. A portion of each VME card's global memory is allocated upon initialization for supporting the message passing mechanism. Access to the message buffer is restricted to read-only for modules that do not own that buffer. An error detection or correction code (e.g. cyclic redundancy check) is appended to the end of a data stream message to contain faults and prevent their propagation to other VME cards.
