Title: Power driving circuit for controlling a variable load ultrasonic transducer
Inventor: MAY JASON
IPC: H03B5/40
Filed: 2006-01-27
Abstract: The present invention is directed to a high-powered (e.g., > 500 W) ultrasonic generator for use especially for delivering high-power ultrasonic energy to a varying load including compressible fluids. The generator includes a variable frequency triangular waveform generator coupled with pulse width modulators. The output from the pulse width modulator is coupled with the gates of an Isolated Gate Bipolar Transistor (IGBT), which amplifies the signal and delivers it to a coil that is used to drive a magnetostrictive transducer. In one embodiment, high voltage of 0-600VDC is delivered across the collector and emitter of the IGBT after the signal is delivered. The output of the IGBT is a square waveform with a voltage of +/-600V. This voltage is sent to a coil wound around the ultrasonic transducer. The voltage creates a magnetic field on the transducer and the magnetorestrictive properties of the transducer cause the transducer to vibrate as a result of the magnetic field. The use of the IGBT as the amplifying device obviates the need for a Silicon Controlled Rectifier (SCR) circuit, which is typically used in low powered ultrasonic transducers, and which would get overheated and fail in such a high-powered and load-varying application.

Title: Queueing events in an interactive media environment
Inventor: FINGER JAMES C
IPC: G11B20/10
Filed: 2006-06-22
Abstract: An arrangement is provided where all applications in an interactive media environment run on a single application thread in a media player. Event queues (819) are utilized to schedule the application thread's processing of workitems (810) corresponding to events that occur in the environment. Workitems (810) include methods to be invoked when the workitem (810) is processed and arguments for the method. Workitems (810) further include a begin time and an end time and are ordered in the event queue (819) first by begin time followed by the order in which they were inserted into the queue. The application thread marks workitems (810) whose begin times corresponds to the current or previous time and then processes marked workitems (822) from the queue in order. Such processing is committed so that once the application thread begins processing of a workitem (822) it does not stop. Workitems (822) are dropped from the event queue (819) if their end times have been passed. ® KIPO & WIPO 2008
