Title: Engine speed control system for outboard motor
Inventor: WATABE HIROSHI
IPC: F02D13/02
Filed: 2005-09-06
Abstract: In an engine speed control system for an outboard motor, overrev prevention control is implemented which determines whether the engine overrevs by comparing the detected engine speed and a desired speed and responds to a determination that the engine overrevs (in which case the cause of the engine speed increase is probably reduced load caused by sucking in of air and/or exhaust gas by the propeller) by driving an electric throttle motor in the direction of reducing the throttle opening, thereby lowering the engine speed to the desired speed.  Owing to this configuration, the problem of decline in thrust owing to intake of air and/or exhaust gas by the propeller can be quickly overcome irrespective of operator skill, thereby improving power performance and steerability.

Title: Method and apparatus for utilizing a directional beam antenna in a wireless transmit/receive unit
Inventor: CHARLTON GREGG ARTHUR
IPC: H04L69/40
Filed: 2004-11-24
Abstract: A method and apparatus for utilizing a switched beam directional antenna in a wireless transmit/receive unit (WTRU) is disclosed. A wireless communication system includes a serving cell, a neighbor cell and a WTRU. The WTRU is configured to generate and steer a directional beam in a plurality of directions. Once the WTRU registers with the wireless communication system, the WTRU receives messages transmitted by the serving cell. The WTRU measures signal quality of messages received in each of a plurality of predetermined directions while steering the directional beam antenna. The WTRU selects a particular one of the directions having the best signal quality. As the WTRU  constantly moves, the WTRU monitors signal quality in the selected direction, and switches to another direction when the signal quality in a current direction drops below a predetermined threshold.
Patent CA-2548029-A1 (CA)
Inventor: ZHAO YUNFEI
IPC: G02B6/02
Filed: 2006-05-23
Abstract: This invention relates to a method and a system for writing fiber Bragg gratings (FBG) having apodized spectrum ("apodized FBG") on optical fibers. An amplitude modulation mask is placed between a focusing cylindrical lens and the optical fiber. By reducing the distance between the amplitude mask and the fiber, the present invention can minimize diffraction effects that may be induced by long propagation distance of a laser beam passing through a small and/or narrow aperture in the amplitude mask. The method and system of the present invention can be applied to write FBG with apodized spectrum with small amplitude mask to achieve full width at half maximum (FWHM) bandwidth (BW) wider than 1.2 nm and to achieve side lobe suppression ratio (SLSR) as high as 30 dB.  These method and system generally increase the laser power efficiency of the laser used in FBG inscription and optimizes the grating index modulation profile.
