Abstract:
An acoustic touch device able to distinguish between user finger touches and other noise-making events includes ultrasonic transmitting and receiving units, and a controller. The ultrasonic receiving unit generates low-frequency electrical signals when the acoustic touch device is touched by an external object or affected by acoustic noise. The low frequency electrical signals cause variation in the output electrical signals of the ultrasonic receiving unit. The controller is configured to power on or power off the ultrasonic transmitting unit according to such variation.

Claim (Index 7):
A method for touch judging by using an acoustic touch device, the acoustic touch device, comprising: an ultrasonic receiving unit configured to receive ultrasonic waves; an ultrasonic transmitting unit configured to emit ultrasonic waves; and a controller electrically coupled to the ultrasonic receiving unit and the ultrasonic transmitting unit; the method comprising:\n monitoring output electrical signal of the ultrasonic receiving unit by the controller and keeping the ultrasonic transmitting unit power off; determining by the controller whether the output electrical signal of the ultrasonic receiving unit is less than a first threshold value; powering on the ultrasonic transmitting unit by the controller if the output electrical signal of the ultrasonic receiving unit was less than a first threshold value; determining by the controller whether output low-frequency electrical signals of the ultrasonic receiving unit increase or not; powering off the ultrasonic transmitting unit by the controller determining if the output low-frequency electrical signals of the ultrasonic receiving unit increases to be above the first threshold value; determining by the controller whether output high-frequency electrical signals of the ultrasonic receiving unit is decreased to be less than a second threshold value; determining by the controller whether the duration time for the high-frequency electrical signal being less than the second threshold is greater than T.
