Abstract: A cover glass pressure-sensitive button for a mobile device is disclosed, a piece of pressure sensor is configured under peripheral of a cover glass for a display of a mobile device. The cover glass can be pressed like a button, and a signal is output from the pressure sensor to trigger a predetermined function for the mobile device when a pressure is applied on the cover glass. In another embodiment, a space is reserved either under the touch panel or under the LCD module. With this configuration, the pressure sensitivity of the cover glass increases because the pressure applied on the cover glass can be fully transferred onto the pressure sensor.

Abstract: A zooming pressure sensor is used to control the zooming of information in a zooming frame on a displayed for a cell phone, portable media device, or an electronic reader. A zooming pressure sensor converts finger pressure into corresponding physical parameter such as conductance, resistance, or charge, which is further processed by a circuit for control parameter of a zooming frame. The magnitude of output parameters is designed in positive relation to zoom-in, and in negative relation to zoom-out.

Abstract: A pressure guiding bump is configured on the center of a pressure gauge to obtain a single “conductivity-pressure” curve feature which is independent from any position wherever a pressure is applied on the guiding bump. When a pressure is applied, the guiding bump guides the pressure against a fixed deformable area to be deformed, whatever the pressure is, the deformed area is nearly a same area. The pressure gauge is extraordinarily adequate to be designed in a weighing machine with parallel connection in between them.
