Patent CA-2246426-A1 (CA)
Title: Electric motor starting circuit
Inventor: MCDONALD STEPHEN PAUL
IPC: H02P1/26
Filed: 1997-02-17
Abstract: An electric induction motor can be given a kick start without excessive current drain on the supply by first connecting a unidirectional supply to a winding of the motor to build up a stationary rotor flux and then applying a starting current to another winding of the motor to produce a stator flux at an appropriate angle (between 0° and 180°) with the stationary rotor flux. Once the motor has begun accelerating the normal running supply can be connected. This starting current may be derived from a capacitance which is charged up during the period of establishing the stationary rotor flux.

Title: Wireless lan with enhanced capture provision
Inventor: KAMERMAN ADRIAAN
IPC: H04L12/28
Filed: 1998-09-03
Abstract: A receiver and a method for operating the receiver, for a station in a wireless local area network using a common wireless communication channel and employi ng a CSMA/CA (carrier sense multiple access with collision avoidance) protocol includes various modes. In normal mode, the receiver follows typical states in order to detect a  message and demodulate data from the message properly. Meanwhile, a proce ss implements a message-in-message (MIM) mode when an energy increase above a specified level is detected. While in the MIM mode, if a carrier is detected , the energy increase is caused by a new message; otherwise, the energy increase is cause d by an interfering station. If the carrier is detected, the receiver begins retraining so that it can start receiving the new message as soon as the first message ends. If no carrier is detected, the receiver waits a specified time to detect a carrier or for the  end of the first message, after which the receiver returns to the beginning of the normal mod e. While in the normal mode, if a message is detected that is not addressed to the station, the receiver enters a hunt mode. While in the hunt mode, the receiver waits for the curre nt message to finish. At the same time, a process implements retraining when both an energ y increase above a specified leveland a carrier are detected. If no carrier is detected  within a specified time, or if the energy level decreases below the specified level, the receiver returns to the beginning of the normal mode.

Title: Method and apparatus for providing multiple multicast communication sessions in an atm destination switch
Inventor: LAU JOSEPH C
IPC: H04L12/56
Filed: 1997-05-16
Abstract: An ATM destination switch (130) comprising an ATM layer device which includes an ATM layer interface (135), a processor (136) with an associated translation RAM (162), and an ATM layer to physical layer interface. The processor decodes incoming ATM cell to obtain a VPI/VCI, and provides additional routing information to the cell for multicasting. The cell with the additional routing information is forwarded to the physical layer device which has a header processor (160), a multicast indicator storage table, in the form of a bit map for storing output line indications and ATM line output interfaces (170). The header processor (160) receives the cell with the additional routing information, reads the routing information, accesses the multicast indicator storage table based on the routing information to determine which output lines the cell is to be provided, and controls the copying of the cell for each output lines so that it may be received at multiple destinations. Thus, an incoming cell which is to be multicast to multiple users will be multicasted using the single VPI/VCI.

Title: Time-shifting apparatus and auto-edit system
Inventor: DANIELS JOHN J
IPC: G11B27/024
Filed: 1997-10-01
Abstract: A method and time shifting event recorder capable of recording portions of a time sequential signal representing an event so that a representation of the event can be produced in a time shifted manner. At any time, the user can input a pause display command, resulting in a first recorded portion of the time sequential signal to be recorded. When the viewer wishes to return to viewing the program, a resume command is played back while simultaneously recording a second recorded portion. An auto-editing device can utilize the play back capabilities of the inventive time shifting event recorder to generate a video tape (50) containing a recorded event that has been automatically edited. During the recording of an event using, for example, a video camera (64) the camera operator selects portions of the recorded event that are to be re-recorded into an edited version. During a post editing process, the selected portions are determined and only the selected portions are re-recorded into the edited version.
