Patent CA-2467233-A1 (CA)
Title: Ultrasonic sensor
Inventor: TAKEICHI MASAKAZU
IPC: G01H7/00
Filed: 2004-05-13
Abstract: An ultrasonic sensor includes a piezoelectric vibrator (1), a reverberation measuring device (5) and a compensating device (2a-2c, 5, 6, 8a-8c, 9a-9c, 10a, 10b). The piezoelectric vibrator (1) vibrates to transmit an ultrasonic wave, receives a reflected wave of the transmitted ultrasonic wave and produces an output signal corresponding to vibration of the piezoelectric vibrator (1). The reverberation measuring device (5) measures a reverberation period of the piezoelectric vibrator (1) from the output signal. The compensating device (2a-2c, 5, 6, 8a-8c, 9a-9c, 10a, 10b) compensates for an operation characteristic of the piezoelectric vibrator (1) in accordance with the measured reverberation period. Thus, the ultrasonic sensor can decrease a reverberation period, which may cause reduction in detection accuracy and impossibility of detection of an obstacle at a short distance.

Inventor: ADY DANIEL D
IPC: A01M31/00
Filed: 2004-07-19
Abstract: A game call system includes a mouthpiece that produces sound by a plurality of reed or membrane portions vibrating against or near a plurality of sound-producing surfaces. Preferably, the game call has two recessed or curved or contoured surfaces on two halves of a generally circular end of the mouthpiece, with an aperture between the two curved/contoured surfaces. These surfaces may be identical, substantially identical, or different, and the reeds or reed portions also may be identical, substantially identical, and or different. Air passes over the reed(s) to create vibrations in the reed(s), and the resulting sound waves pass through the center aperture of the mouthpiece into the resonating chamber of the call, and through any resonating tube or other member that may optionally be present. The multiple sound-producing regions allow for more complex and/or realistic sounds than conventional single sound-producing region and single reed calls.

Patent CA-2488571-A1 (CA)
Inventor: NEW WEN JING
IPC: H04L27/00
Filed: 2003-06-10
Abstract: Techniques for reducing the time required for frequency scan in acquisition are disclosed. In one aspect, received power measurements are made at one or more of the possible carrier frequencies and system search is performed on one or more of those frequencies when the power measurement exceeds a threshold.  In another aspect, the power is measured at one or more frequencies in a band of frequencies surrounding a frequency at which the measured power exceeded a threshold. If the measured power at one or more of the frequencies in the band exceeds a second threshold, a system search is performed at one or more of those frequencies. In yet another aspect, frequencies meeting certain criteria are sorted in order of measured power prior to system search or further power measurement, and subsequent processing is performed in order of descending measured power. Various other aspects are also presented. These aspects have the benefit of reducing acquisition time, which results in faster system access and allows for more efficient use of system resources.
