Abstract: Methods and device for in-system firmware update in an information output device are provided. In one aspect, a method of firmware update in a display device receives a set of data in an image format through a video signal input channel of an input port of the display device. The set of data is converted from the image format to an instruction set format that is different from the image format. A first set of instructions that is used to operate the display device is updated with the set of data in the instruction set format.

Abstract: A method and system for managing images and associated geographic location data in a mobile device uses an integrated camera to generate one or more images. After generating an image, the system determines a geographic location associated with the image. The system then stores the image, the associated geographic location data, and a record of the association in the mobile device's storage component. The system may also associate supplemental information, such as telephone number, category, and street address, with the image. The system provides one or more display modes for displaying the image and the associated information. The display modes may include a list mode for displaying multiple images and portions of the associated data and a detail mode for displaying a selected image and the full set of associated data. The system may also provide a map display mode for displaying locations associated with one or more images on a map of a geographical area.

Abstract: A keypad assembly includes a pressing surface layer, a pattern layer, an elastic layer, a light guiding layer, and a pressing bottom layer. The pattern layer is under the pressing surface layer. The elastic layer is located between and interlocks the pattern layer and the light guiding layer by adhesive. The pressing bottom layer adheres to the light guiding layer. The keypad assembly has an ideal appearance by lights collection of the light guiding layer. User can feel comfortable when pressing the keypad assembly because of the elastic layer's buffering effect.

Abstract: A keypad assembly (10) is described. The keypad assembly (10) includes a press layer (11) made of transparent material and a pattern layer (12) arranged under the transparent press layer (11). The transparent press layer (11) forms a plurality of buttons (111). The pattern layer (12) is aligned with and attached to the transparent press layer (11). The pattern layer (12) is made of translucent material. An ink is screen-printed to the pattern layer (12) to form keypad numerals/symbols (123).

Abstract: A keypad assembly (100) includes a first soft layer (10), a stiff layer (20) mounted to the first soft layer, an optical layer (40) located under the stiff layer, and a second soft layer (50) mounted to the optical layer. The first soft layer has at least one protrusion (112) formed thereon. The stiff layer has at least one icon (222) formed thereon. The at least one icon corresponds to the at least one protrusion. The optical layer has at least one focusing unit (42) formed thereon. The at least one focusing unit corresponds to the at least one icon. The second soft layer has at least one switch point (522). The at least one switch point corresponds to the at least one protrusion.

Abstract: A heat dissipating device comprises a dust-collecting mechanism installed at the air vent passage of a fan, and thus the dust or particles mixed in the airflow of the fan shall be collected on the top of the dust-collecting mechanism; the dust-collecting mechanism can be taken out frequently to remove and clean the collected dust or particles, so that the airflow of the fan can be kept normal and the dust deposited on the surface of the metal fins of a heat sink can be decreased greatly as to normally maximize the heat dissipating efficiency for the heat dissipating device for a long period of time and maintain the heat generating source to operate normally at a permissible temperature.

Abstract: A hand-held information equipment provided with dynamic image display and wireless network transmission function s includes a built-in process software to set up/judge command codes of operation keys; being on line with multiple video cameras through a control unit to display pictures transmitted from the camera; and sends signals for real time control of the camera to rotate, adjust elevation and focus in shooting.
