Abstract: When charging a battery in an electronic device, if a charging current or voltage is too high, the electronic device sends a command to stop the charging. However, if an error occurs in the charge circuit, leading to continuous charging of the battery instead of stopping the charging, then the electronic device enters a power consumption mode to consume electric power charged to the battery in the electronic device. This reduces damage due to overcharging the battery.

Abstract: A portable electronic device with power failure recovery, powered by a main power source, the device comprising a power detection module, a processor, a timing unit and a power management unit. The power detection module detects an output characteristic from the main power source and asserts an interrupt signal if the characteristic is below a threshold value. The processor asserts a turn-off signal and an enable signal in response to the interrupt signal. The timing unit asserts a notification signal at a predetermined time interval when the enable signal is asserted. Upon receipt of the turn-off signal, the power management unit disconnects the main power source from a circuit block. Moreover, the power management unit reconnects the main power source to the circuit block when the notification signal is asserted and the output characteristic of the main power source is beyond the threshold value.

Abstract: The present invention is related to an apparatus and a method for improving the quality of printing. The reference timings are adjusted by random values to decrease the cyclic unevenness of images associated with the conventional technique. The random values may be generated by the apparatus itself or may be received from an external device, such as a personal computer. The distance between two adjacent dots changes, and the unevenness of images is scattered to provide a higher quality of printing.

Abstract: A method of displaying additional colors is provided to enable a flat panel display (FPD) to display a required color which is originally unavailable due to hardware limitations of the FPD by using two available colors of the FPD, such as, a first and a second color. At least a pixel of the FPD is initiated to display the first color and a response time of the FPD is allowed to substantially elapse. Next, the pixel is initiated to display the second color, and at least a time equivalent to a display-achieving period is allowed to elapse, in which the period is based on, numerically, the first and second colors, the required color, and the response time. The pixel is then initiated to change its color alternately in a sufficiently small scale, thus achieving displaying the required color substantially.

Abstract: An image output device includes two color ink cartridges. The first color ink cartridge is filled with yellow ink, magenta ink, and cyan ink. Besides, the yellow ink nozzle, first magenta ink nozzle, first cyan ink nozzle eject the yellow ink, magenta ink, and cyan ink respectively. The second color ink cartridge is filled with black ink, magenta ink, and cyan ink.

The second magenta ink nozzle has a diameter smaller that of the first magenta ink nozzle, and the second cyan ink nozzle has a diameter smaller that of the first cyan ink nozzle. The color ink cartridge ink having the nozzle with small diameter is driven to create small ink drops or light ink drops. It improves the image resolution and creates a six-color tone expression. Moreover, the cost of manufacturing the printhead will not increase and the controlling method will not become complicated.
