Abstract: A touchpad keyboard includes a microprocessor; a touchpad module comprising a flexible, rectangular, optically transmissive touchpad and a touchpad controller electrically interconnecting the touchpad and the microprocessor; and an electronic paper (e-paper) display module comprising a flexible, rectangular e-paper display disposed under the touchpad, and an e-paper display controller electrically interconnecting the e-paper display and the microprocessor. The e-paper display includes a plurality of selection keys, each selection key being adapted to cause the microprocessor to access one of a plurality of keyboard layout pages to display on the e-paper display in response to pressing thereon.

Abstract: A touch pad includes a bottom substrate formed of plastic material; a second conduction layer adhered to the bottom substrate; a plurality of spaced pressing structures formed on the second conduction layer and each comprising a sensing layer adhered to the second conduction layer, a contact layer formed of flexible resistive or piezoelectric material and adhered to the sensing layer, and a connection layer adhered to the contact layer; a first conduction layer adhered to the pressing structures; and a top substrate formed of plastic material and adhered to the first conduction layer.

Abstract: A third back-up light for vehicles is disclosed. A back-up indicating light of the present invention is disposed on corners or lateral area of a rear lamp set, and works synchronously with the original back-up light so as to enhance insufficient warning effect of the original back-up light of the rear lamp set as well as increase visible angle or warning area of the back-up light. Moreover, the third back-up light is integrated with the rear lamp set without influence on original function of the rear lamp set. Thus the assembling of the present invention is finished at the same time with the assembling of the rear lamp set so as to become a general specification for the rear lamp set. Furthermore, the third back up light can emit white light, light with other colors, or blinking light, all achieve the warning effect.

Abstract: An auxiliary lamp of a side view mirror 1 includes a light providing backup illumination on inner side and a multidirectional turn-signal lamp on outer side thereof, both on bottom area thereof. The multidirectional turn-signal lamp indicates three directions of turns-front side, rear side and lateral side. The light providing backup illumination only works when the car lights and the reversing lamps acts synchronously so that the light illuminates the rear wheels while revering at night. And the multi-directional turn-signal lamp works synchronously with original car turn-signal lamps so as to make the side view mirror has function of front-side, lateral-side and rear-side indications. Therefore, the safety and convenience of vehicles while turning at night are improved. The performance and the added value are also increased.
