Granted: 2000-01-01
Abstract: To stabilize the revolutions of a model engine in lower speed and improve the response of the engine in lighting acceleration by installing an electronically-controlled fuel injector on the engine with the fuel under desired pressure. A model engine in operation produces air pulsating pressure in its crankcase. This pressure in the crankcase is lead into the air-pressure suction part 51 on a fuel-pressure control valve. The air-pressure suction part 51 includes an adjustable overpressure leakage valve 57. The air-pressure suction part 51 connects to the control air-pressure supply port 54 on the fuel tank through a check valve 56. The check valve 56 leads the positive air pulsating pressure into the fuel tank by a control air-pressure supply pipe. When the pressure in the fuel tank falls below a specified value, all the positive air pulsation pressure lead into the air-pressure suction part 51 is fed into the fuel tank. When the pressure in the fuel tank reaches the specified value, on the other hand, all the air pressure lead into the air-pressure suction part 51 is released to the outside through the operation of a control ball 60 of the overpressure leak valve 57. The check valve 56 serves to stop air pressure flowing counter from the fuel tank.

Title: Method and apparatus for electronically embedding directional cues in two channels of sound
Inventor: WOOD PAUL NIGEL
IPC: H04S3/00
Filed: 1998-01-20
Granted: 2000-05-21
Abstract: The system and method of the present invention provides surround sound effects through a two channel system. In one embodiment, the first channel is connected to one speaker (e.g., the right speaker) of a headset and the second channel is connected to the other speaker (e.g., the left speaker) of the headset. Thus, surround sound effects, including providing effects to distinguish front and rear sound sources, are provided through headsets which isolate the sound provided to right ear and the left ear of the listener. Alternately, the signals are output to a two speaker system, enabling surround sound effects to be output through home stereo systems not necessarily configured specifically for surround sound. Modified head related transfer functions (HRTF) are applied to each rear sound signal. The modified HRIF for each rear signal is generated by removing the head related transfer function corresponding to the front cener signal from the HRTF corresponding to the rear sound signal. This provides the audible effect of distinguishing more clearly sounds originating in front of the listener or to the rear of the rear of the listener while not limiting the perceived bandwidth of the signal.

Filed: 1998-05-28
Granted: 2000-06-21
Abstract: A method provides for the detection of the geographic location of a mobile station within a mobile network. The mobile station detects signal characteristics for signals generated by neighboring cells to create a report of signal characteristics corresponding to the location at which the mobile station resides. This report is then compared against the database of signal signatures identifying geographic locations within the cell in which the mobile station is known to be positioned. The signal signatures are then used to detect either an exact match or an approximate match to give position information of the mobile station within the cell.

The ultrasonic surface wave generator/receiver may comprise a focused transducer, having a focusing element integral therewith or separate therefrom, operatively connected to a wedge-like coupler. Longitudinal ultrasonic waves generated by the transducer are at least partially focused by the focusing element and then imparted onto the tooth surface by the coupler which has a contact surface in contact with the tooth surface being tested. The coupler also enables ultrasonic surface wave reflections to be received by the transducer.
