Patent CA-2254659-A1 (CA)
Title: Electric motor rotor holding arrangement
Inventor: JONES CHRISTOPHER C
IPC: B60L15/20
Filed: 1998-11-19
Abstract: A hill-holding arrangement for an electrically driven vehicle includes a vehicle with a "gas pedal" which generates a torque command signal T CMD. A switch (314) couples T CMD to a motor controller (316, 14) which drives the motor (40) and therefore the vehicle. When the "gas pedal" calls for zero torque, and the vehicle speed is zero, the switch responds to logic (FIGURE 5), and substitutes a position-holding torque command signal T.THETA. for the operator-controlled torque command signal T CMD. Position controlling torque command T.THETA. is generated by a controller (312) which receives a position signal representative of the angular position .THETA. of the rotor. The position-holding torque control loop then produces such torque as may be required to prevent the rotor of the motor from moving from its commanded position.

Title: High performance data cable
Inventor: WHITE MARK W
IPC: H01B7/18
Filed: 1999-04-15
Abstract: High performance data cables are provided that allows for future growth in networking speeds.  The high performance data cables achieve this result while satisfying the dimensional requirements set by the EIA/TIA 568-A standards as well as fire performance safety requirements of the National Fire Protection Association (NFPA). High performance data cables of this invention achieve the above by controlling parameters that influence impedance performance, near-end crosstalk performance and attenuation. A  separating filler material is used to maximize the pair-to-pair distance while maintaining an overall maximum outside diameter of .250". This construction benefits crosstalk performance, as both electrical and magnetic field intensities are inversely related to distance and dielectric constant (crosstalk is made up of capacitative and inductive coupling, with inductive coupling becoming significant at frequencies above 50 MHz). Balancing between parameters that influence impedance, near-end crosstalk and attenuation performance by choice of materials and physical dimensions of the filler material, insulation material, jacket material and conductor, the overall performance of the data cable of this invention is achieved. A  standard for the high performance data cables of this invention is also disclosed.

Title: Method and system for billing remote calls as if made from a primary line
Inventor: MALIK DALE W
IPC: H04M15/00
Filed: 1999-06-28
Abstract: A method and system for billing remote calls includes the provisioning of an active terminating attempt trigger on a subscriber's primary line. To make a long-distance call from a remote location, the subscriber calls a service control node and provide a destination calling line number and the subscriber's primary line number (e.g., home telephone number). The SCN assembles the data into a string and includes a feature access code. This string is transmitted to a switch that recognizes the feature access code and transmits a message to a service control point. The service control point also recognizes the feature access code and reassembles the message into a call structure containing the primary line number, the destination line number, and a code indicating that the message should be reassembled. This message is transmitted back to the switch which then routes the call to the primary line switch where the trigger is encountered. The primary line switch then transmits the call information up to an SCP an includes the code. The SCP detects the code and reassembles the data to instruct the switch to route the call to the destination number through the primary line number. The switch routes the call to the destination number and the primary line number is billed for the call.
