Patent CA-2213600-A1 (CA)
Inventor: NERONE LOUIS R
IPC: H02M7/5383
Filed: 1997-08-21
Abstract: A ballast circuit for a gas discharge lamp comprises a resonant load circuit incorporating the gas discharge lamp and including a resonant inductance and a resonant capacitance. A d.c.-to-a.c. converter circuit induces an a.c. current in the resonant load circuit. The converter circuit comprises first and second switchesserially connected between a bus conductor at a d.c. voltage and a reference conductor, and which are connected together at a common node through which the a.c. load current flows. The first and second switches each comprise a control node and a reference node, the voltage between such nodes determining the conduction state of the associated switch. The respective control nodes of the first and second switches are interconnected. The respective reference nodes of the first and second switches are connected together at the common node. A gate drive arrangement regeneratively controls the first and second switches, and comprises a driving inductor mutually coupled to the resonant inductor in such manner that a voltage is induced therein which is proportional to the instantaneous rate of change of the a.c. load current. The driving inductor is connected between the common node and the control nodes. A second inductor is serially connected to the driving inductor, with theserially connected driving and second inductors being connected between the common node and the control nodes. A bidirectional voltage clamp is connected between the common node and the control nodes for limiting positive and negative excursions of voltage of the control nodes with respect to the common node.

Filed: 1998-04-08
Abstract: The interactive toy includes a speech synthesizer for converting digital data representative of speech into audible synthesized speech; an infra-red transceiver for wirelessly communicating infra-red messages over a field-of view to a second toy; a microphone; and a selector for selecting between a transmission mode and a stand-alone mode. The toy is programmed so that, in the transmission mode, it receives a first infra-red signal from a second toy identifying a synthesized speech phrase generated by the second toy, supplies selected digital speech data representative of a reply synthesized speech phrase to the speech synthesizer in response to the first signal, and transmits a second infra-red signal to the second toy indicative of the selected reply phrase. In the stand-alone mode, the toy monitors the microphone for sound input, and supplies selected digital speech data to the speech synthesizer after the sound input has ceased. The toy also includes a motor, connected to a movable body part, which is actuated in timed relation to the synthesized speech, in order to mimic human mannerisms when speaking.

Title: Systems and methods employing video combining for intelligent transportation applications
Inventor: SMOOT LANNY STARKES
IPC: G08B15/00
Filed: 1996-12-12
Abstract: A multicamera surveillance system (300) connects video surveillance cameras (104) to a video bridge (310). One or more users (108) in the same or different locations may obtain video from one or more video cameras from this bridge, without having a direct connection to the video cameras. The invention may use graphic combining techniques so that the video inputs may be superimposed on a graphic image, such as a map. The video surveillance cameras may be pannable electronic cameras which provide a user selectable panorama of the scene under surveillance. The inventive system provides a video surveillance system which is simple to understand and use. It also provides a centralized video bridge which may be used to provide a number of monitoring stations to independently view video inputs of interest. Thus, state and local police, EMS dispatch, fire stations, trucking companies, commuters, or any other interested party may be able to view locations of interest using relatively inexpensive equipment, such as a computer and joystick.

Title: Golf club-distance selector
Inventor: FONG WING SON
IPC: A63B57/00
Filed: 1998-09-02
Abstract: A golf club-distance selector, custom tuned by a golfer for personalized use, comprises a base disk, on which are successively and concentrically located an intermediary and windowed disk. After performing several golf shots with a selected club, shots which are characterized by the lengths the normal golf ball fly through the air, an average length value is estimated and identified on the base disk. This value is matched with the selected club inscribed on the intermediary disk. The base and intermediary disks are attached in the above position, thereby "locking" the selected golf club to the average length value, simultaneously "tailoring" all the other golf clubs to the individual's golf swing, thus personalizing the selector. An aperture is provided on the windowed disk, indicating a length, and a golf club, far normal playing conditions. Also indicated for the same length are other golf clubs for different playing conditions.      The selector comprises the full range of golf clubs.
