Abstract: A measuring method of touch sensitive area size of a SAW sensor module is provided. The SAW sensor module comprises a substrate configured for propagating SAW, a first transmitter and a first receiver corresponding to a first axis, a second transmitter and a second receiver corresponding to a second axis. The SAWs emitted by the first transmitter at least pass through a first initial distance xi, propagate through a second axis length y after reflected by a first SAW reflecting bar, and enter the first receiver after reflected by a second SAW reflecting bar. The SAWs emitted by the second transmitter at least pass through a second initial distance yi, propagate through a first axis length x after reflected by a third SAW reflecting bar, and enter the second receiver after reflected by a fourth SAW reflecting bar.

Abstract: Described is a sensing device of a surface acoustic wave (SAW) touch panel having a new reflector columns and rows arrangement. As compared to the conventional design in the art where each of the reflector columns and rows are arranged from thinness to thickness, each of the arrangements of the reflector columns and rows herein is composed of a plurality of uniformly disposed reflectors having several sub-reflectors isolated with a gap or gaps.

The apparatus for detecting position includes a frame, a plurality of first signal sources, a plurality of first signal receivers, a plurality of second signal sources, a plurality of second signal receivers, and a processor. The frame is comprised of a first portion, a second portion, a third portion, and a fourth portion. The plurality of first signal sources are disposed along the first and the second portions to emit the signals configured to detect a coordinate in a first direction. The plurality of first signal receivers are disposed along the third and the fourth portions, corresponding to the plurality of first signal sources, to receive the signals from the plurality of first signal sources respectively. The plurality of second signal sources are disposed along the first and the fourth portions to emit the signals configured to detect a coordinate in a second direction.

Abstract: The present invention relates to a method and apparatus for generating driver signals of SAW touch panel. The method includes the steps of: sending a trigger signal continuously by referring to an input signal, wherein the trigger signal is sent when the input signal is within a predetermined range; generating a surface acoustic wave according to the trigger signal; transmitting the surface acoustic wave to at least one transducer via a touch surface; and detecting the input signal via at least one transducer. Moreover, the input signal is kept on a predetermined level when the surface acoustic wave has not been received by the transducer and when a noise signal from circuits outside the transducer has not been added in the input signal. The predetermined level is within the predetermined range. The sensing accuracy of the SAW touch panel can be enhanced because the noise signal has less effect on the driver signals.

Abstract: Described is a sensing device of a surface acoustic wave (SAW) touch panel having a new reflector columns and rows arrangement. As compared to the conventional design in the art where each of the reflector columns and rows are arranged from thinness to thickness, each of the arrangements of the reflector columns and rows herein is composed of a plurality of uniformly disposed reflectors having several sub-reflectors isolated with a gap or gaps. In this manner, a vibration wave transmitted through each of the reflector columns or rows can be reflected and then collected at a target transducer in an uniform pattern with respect to each portion of each of the reflecting columns and rows, thereby avoiding the problem encountered in the prior art.

Abstract: Described is a device and method for determining a function represented by a specific continuous relative motion between/among multitouch inputs on signal shield-based position acquisition type touch panel. The method comprises the steps of acquiring a minimum and maximum ordinate and abscissa values between/among the multitouch inputs; forming a rectangle based on the minimum and maximum ordinate and abscissa values; monitoring a sequential variation of an contour of the rectangle; and determining a gesture associated with the specific continuous relative motion of the multitouch inputs based on the sequential variation of the rectangle and relating the gesture to the function.
