Title:
AN ULTRASONIC SENSING DEVICE CONNECTING WITH AN ADJUSTABLE BORN STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2009/062333
Kind Code:
A1
Abstract:
An ultrasonic sensing device connecting with an adjustable born structure includes
a gearing device (42), a horn structure (31,41, 51) and a ultrasonic transceiver
(32,44). The horn structure (31,41, 51) is spiral connected to the gearing device
(42) by a helical gear (43), and the ultrasonic transceiver (32,44) is mounted
on the end of the helical gear (43) When the horn structure ( 31,41, 51) is moved
to the first position by the gearing device (42), the ultrasonic transceiver
(32,44) is applied as a different state sensing or on/off controlling; when the
horn structure ( 31,41, 51) is moved to the second position by the gearing device
(42), the ultrasonic transceiver (32,44) is applied as a measurement of the time-of
flight, and the result of the measurement is converted into digital signal to
process control.
