Abstract:
The present invention relates to a defogging and defrosting devices for the protective lens of camera, which includes a heater that is coupled to a control circuit panel, a thermal gasket that is in contact contacting with the heater, receives the heat from the heater and transmits the heat to the glass or mirror object which contacts with in order to avoid and prevent the loss of lucidity of the glass or mirror object due to humidity. The defogging and defrosting device is installed on the body of the camera instead of on the protective lens in order to avoid shading the camera view and to facilitate the removal of protective lens while adjusting the focus of the camera. It also facilitates the replacement of the protective lens of the camera.

Abstract:
An electronic device and a method for driving an internal function block of a processor of the electric device to operate in a linear region. The electronic device comprises a processor having two multiple purpose pins (MPP1 and MPP2), an external device connection port, and two resistance elements. The external device connection port is further connected to the MPP1 and at a tested voltage. The first resistance element is connected between a high level voltage and the external device connection port. The second resistance element is connected between the external device connection port and the MPP2. The processor is configured to output the high or low level voltage at MPP2 when the tested voltage is in a non-linear operating region, to guarantee the tested voltage to a linear operating region of the function block which is coupled to the MPP1 by a multiplexing design.
Abstract:
An ExpressCard solid-state storage device is disclosed herein, which receives an access command coming from a computational device and accesses data accordingly. The ExpressCard solid-state storage device includes a circuit board, an ExpressCard interface, a flash memory, and a controller. When the ExpressCard interface of the storage device is inserted into a corresponding interface of the computational device, the ExpressCard solid-state storage device is electrically connected with the computational device. Then the controller receives a write, read or erase command, which is from the computational device and through the ExpressCard interface, and writes data into the flash memory or reads/erases data from the flash memory accordingly.
Abstract:
A portable electronic device is provided. Connector includes the first and data pins. Processor includes input and output pins and detection pin coupled to the input pin. First resistor is coupled between the detection pin and first voltage. When the processor detects that the first and second pins of charger are coupled to the first and second data pins of the connector, the processor provides switching signal to the selector, so as to couple the first and second data pins of the connector to the input and output pins of the processor, respectively, and to provide second voltage different from the first voltage, to the second pin of the charger via the output pin. The processor obtains charging current value of the charger according to voltage of the detection pin. The charger includes second resistor coupled between the first and second pins.

Abstract:
An electronic device includes a housing, a connector port and a switching device. The connector port receives a peripheral device. The processor is electrically connected to the connector port and includes a detection pin and a 1-wire pin. The switching device is coupled between the connector port and the processor to selectively connect the connector port to one of the detection pin or the 1-wire pin. When the peripheral device is inserted into the connector port, the processor controls the switching device to connect the connector port to the detection pin to determine whether the connected peripheral device is a 1-wire device. When the processor determines that the connected peripheral device is a 1-wire device, the processor controls the switching device to connect the connector port to the 1-wire pin and the processor executes 1-wire communication with the peripheral device via the 1-wire pin.
