Patent CA-2345456-A1 (CA)
Title: Method and apparatus for controlling lights
Inventor: HOFFKNECHT MARC OLIVER
IPC: H05B37/02
Filed: 2001-04-27
Abstract: A control circuit for controlling the operation of an electrical lighting device, such as a gas discharge ballast or an incandescent lamp, and which can replace a standard switch and requires connection only to the hot wire of an AC power line. The control circuit has a switch encoder which couples two opposite polarity thyristors between the hot wire of an AC power line and the hot wire running through the wall to the fixture. The thyristors are controlled by switches such that the AC waveform is transmitted over the power wires either with the small zero crossing step delays inherent in thyristor switching, or with a chopped waveform such that the transmitted AC waveform has positive going zero crossing step delays or negative going zero crossing step delays. The transmitted AC power waveform is used to power the electrical lighting device as well as to control the operation of the electrical lighting device by connection to a decoder.  The decoder decodes the transmitted AC power waveform by generating a voltage pulse waveform having pulse widths corresponding to the duration of the zero crossing step delays, determining the differences in time spans between successive pairs of pulse falling edges and comparing these time differences with a threshold duration. A load controller receives the decoder output and appropriately controls the operation of the electrical lighting device. Since the waveform chopped positive and negative going step delays are generated near the zero crossing of the AC voltage waveform, the transmitted AC power waveform does not generate any substantial signal distortion or cause any significant power factor loss.

Patent CA-2362076-A1 (CA)
Inventor: ASADA RYUJI
IPC: B60K23/04
Filed: 2001-11-14
Abstract: In a vehicle in which a torque generated in an engine is transmitted to driven wheels through a torque converter and an automatic transmission, when a speed ratio e in the torque converter is equal to or larger than a predetermined value (e.g., 0.85), and the accuracy of estimating a capacity .tau. of the torque converter is low, an estimated engine torque Ti is multiplied by a torque ratio k of the torque converter to estimate a drive torque Td. When the speed ratio e in the torque converter is smaller than the predetermined value, and a response lag is produced in the transmission of the engine torque, a drive torque Td is estimated from an engine rotational sped Ne and the speed ratio e in the torque converter. During shifting of the automatic transmission, a drive torque Td is estimated from a wheel speed V. Thus, a correct drive torque can be estimated.
