20120198258 | WIRELESS INPUT DEVICE WITH A POWER SAVING SYSTEM - An input device with a power saving system is provided for reducing the power consumption of the input device when the input device is at rest. The input device may include a sensor, a rest mode switch, control logic and a current controller. The sensor may be configured to obtain an image data in response to a light incident on the sensor. The rest mode switch may be configured to set the input device to various levels of rest modes when it is inactive. The control logic may be coupled to the rest mode switch and the sensor. The control logic may be configured to set the input device to process a portion of the image data on the sensor array during a wake up detection operation when the input device is at rest. The current controller may be coupled to the control logic and the sensor and configured to control the current supply limited to a section of the sensor array containing the portion of image data that is being processed by the input device during the wake up detection operation. | 08-02-2012 |
20140300548 | NAVIGATION DEVICE AND POWER SAVING METHOD THEREOF - A navigation device includes an image sensor, a processing unit, a main clock circuit and an auxiliary clock circuit, wherein a clock frequency of the auxiliary clock circuit is much lower than that of the main clock circuit. The image sensor captures a predetermined number of image frames in a burst period. The processing unit is configured to calculate a displacement according to the image frames, to disable the main clock circuit after the predetermined number of image frames have been captured by the image sensor and to restart the main clock circuit with the auxiliary clock circuit before the end of the burst period. | 10-09-2014 |
20150305127 | OPTICAL NAVIGATION SENSOR WITH INTEGRATED CHARGE PUMP - An optical navigation sensor includes: a driving circuit and a charge pump. The driving circuit is employed for driving a light source externally connected to the optical navigation sensor. The charge pump is employed for intermittently performing an operation of providing a first supply voltage to the light source. When the driving circuit drives the light source, the charge pump does not perform the operation of providing the first supply voltage to the light source. | 10-22-2015 |
20150338931 | DRIVING CIRCUIT WITH FAULT DETECTION AND OPTICAL INPUT DEVICE HAVING THE SAME - The present disclosure provides a driving circuit, which includes a switch, a driver unit, a fault detection circuit, and a processor. The switch is coupled between a power terminal and an anode of a light emitting diode (LED) of a light source. The driver unit is coupled between a cathode of the LED and a ground for generating a driving current according to a control signal. The fault detection circuit operatively detects whether the cathode of the LED is shorted and generate a fault signal when detected that the cathode of the LED is shorted. The processor initiates a fault detection period, during which the processor turns off the switch and the driver unit causes the cathode of the LED to be floating while activates the fault detection circuit to detect whether the cathode of the LED is shorted. | 11-26-2015 |
