Patent CA-2298913-A1 (CA)
Inventor: QUIGLEY JON M
IPC: B60R16/03
Filed: 2000-02-17
Abstract: An electrical interface for connecting a truck electrical system to a trailer electrical system. The electrical interface includes a solid-state switching device for selectively connecting a power source in the truck electrical system to a circuit in the trailer electrical system. If a fault is detected in the provision of power to the circuit in the trailer electrical system, the solid-state switching device reduces the flow of power or disconnects the power source from the circuit in the trailer electrical system. A microcontroller system connected to the truck electrical system transmits control signals to the solid-state switching device to control the flow of power from the power source to the circuit in the trailer electrical system in accordance with instruction signals received from the truck electrical system. The solid-state switching device includes a transistor switch connected between the power source and the circuit in the trailer electrical system and a transistor driver circuit connected to the microcontroller system to control the operation of the transistor switch. The microcontroller system includes a processor and a transceiver that conveys data transmitted between the processor and the truck electrical system. The electrical interface may also include a daughter board connector for connecting an external circuit, such as a communications circuit, to the electrical interface that enables the processor to communicate data with the circuit in the trailer electrical system using an existing electrical connection to an output of the electrical interface.

Patent CA-2305457-A1 (CA)
Inventor: PIAZZALUNGA GIOVANNI
IPC: F04B49/10
Filed: 1999-08-02
Abstract: A method for the starting and steady-state supply of a permanent-magnet synchronous motor, particularly for driving a centrifugal hydraulic pump. The method comprises three successive steps: a first learning step, a second starting step, and a third steady-state step. During the first step, the rotor is turned through two angles of 180 mechanical degrees in the same direction, storing the parameters of the rotor and particularly determining the initial current and the mechanical zero point of the rotor. During the second step, by generating with a power supply (inverter) a practically sinusoidal current waveform, the rotor is started with a higher current than the starting current and with a low frequency which gradually increases, waiting for the rotor at its transit through 80, 100, 260 and 280 mechanical degrees. Once the intended steady-state speed has been reached, a practically sinusoidal current is applied and the rotor is waited for at transit through the zero points. The position of the rotor is checked with a linear magnetic position sensor.

Patent CA-2312509-A1 (CA)
Title: Open cable locating for sheathed cables
Inventor: AMINOT GILLES
IPC: G01R31/02
Filed: 2000-06-27
Abstract: Open circuit faults in a cable are located by applying a step function DC voltage to one end of a conductor along the cable, for example the metallic shield along a fibre optic cable. The DC current along the conductor is measured over a sampling period and integrated to determine the capacitive charge on the cable. The distance between the end of the conductor and the open circuit fault is computed from the calculated charge and the known capacitance per unit length of the conductor.      The DC current in the conductor is measured by sampling the current at a predetermined sampling frequency. The sampling frequency is preferably an integral multiple of the local AC mains power frequency, either 60 Hz or 50 Hz to eliminate the effect of induced AC voltages in the calculations. To eliminate the effects of a resistive fault, the method may include the steps of determining the conductor resistance and subtracting from the calculation of capacitive charge a DC  fault current that is calculated from the conductor resistance and the DC voltage. An apparatus for carrying out the method is also disclosed.
Patent CA-2313958-A1 (CA)
Inventor: EDWARDS PAUL K
IPC: G01F15/06
Filed: 2000-07-17
Abstract: A metering device has a magnet with ten poles which is driven to rotate by a gear connected to a source of rotation that is proportional to fluid flow, the passage of time, or other phenomenon. A reed switch is mounted so that rotation of the poles of the magnet, into and out of a position adjacent to the reed switch causes the reed switch to open and close as the magnet rotates. The opening and closing of the reed switch causes a step change in voltage applied to an electronic device which increments a counter. A second reed switch spaced from the rotating magnet sufficiently so that it remains normally open can act as a sensitive device for detecting the presence of extraneous magnetic fields that might interfere with the operation of the first reed switch.

Abstract: A method for multiplication of a point P on elliptic curve E by a value k in order to derive a point kP comprises the steps of representing the number k as vector of binary digits stored in a register and forming a sequence of point pairs (P1, P2) wherein the point pairs differed most by P and wherein the successive series of point pairs are selected either by computing (2mP,(2m+1)P) from (mP,(m+1)P) or ((2m+1)P,(2m+2)P) from (mP,(m+1)P). The computations may be performed without using the .gamma.-coordinate of the points during the computation while allowing the .gamma.-coordinate to be extracted at the end of the computations, thus, avoiding the use of inversion operations during the computation and therefore, speeding up the cryptographic processor functions. A method is also disclosed for accelerating signature verification between two parties.
