20090189860 | METHOD FOR REDUCING POWER CONSUMPTION OF WIRELESS MOUSE - The present invention provides a method for reducing power consumption of a wireless mouse. At least two sets of mouse moving data are combined into a single packet to be transmitted to a wireless signal receiver. In the wireless signal receiver side, the single packet is divided into the at least two sets of mouse moving data. Since the frequency of transmitting these mouse moving data is reduced, the power consumption of operating the wireless mouse is reduced. | 07-30-2009 |
20090261991 | KEYBOARD DEVICE - The present invention relates to a keyboard device. The keyboard device includes a base, a main circuit board, a base cover, a touching membrane switch, a touching thin plate, an upper cover and a plurality of keys. The touching membrane switch is activated to implement a predefined hot key function so as to reduce fabricating cost. | 10-22-2009 |
20090303063 | VOLTAGE DETECTING CIRCUIT - The present invention relates to a voltage detecting circuit for detecting a voltage range of a power source. The voltage detecting circuit includes a micro controlling unit, a boost circuit and a plurality of divider resistors. The micro controlling unit includes a general input/output port and a controlling input/output port. The boost circuit provides a constant voltage. A judgment voltage is obtained according to the divider resistors, the constant voltage and a voltage of the power source. A digital level signal is issued by the general input/output port according to the judgment voltage. In response to the digital level signal, the micro controlling unit generates a corresponding prompt associated with the voltage status of the power source. | 12-10-2009 |
20100056056 | SYNCHRONOUS WIRELESS TRANSMISSION SYSTEM AND SYNCHRONOUS WIRELESS TRANSMISSION METHOD - A synchronous wireless transmission method is used in a synchronous wireless transmission system including a first wireless device for generating a wireless signal, a second wireless device for generating a second wireless signal, and a wireless signal receiver for receiving the first and second wireless signals. The wireless signal receiver receives the first wireless signal in the first receipt time segment and the second wireless signal in the second receipt time segment. When the first or second wireless signal is received, the wireless signal receiver issues a responding signal to the first or second wireless device. According to the responding signal, the first and second wireless device determines whether the time of issuing the first or second wireless signal to the wireless signal receiver is adjusted. | 03-04-2010 |
20100090661 | AUTOMATIC MOUSE CHARGING SYSTEM - An automatic mouse charging system includes a charger plate and an automatically chargeable mouse. The charger plate includes an audio signal emitter for emitting an audio signal and a charging module for providing electric energy. The automatically chargeable mouse includes a mouse case, an electric energy storage element, multiple audio signal receivers, a driving mechanism, and a control unit. The audio signal receivers are used for receiving the audio signal. The control unit is used for discriminating one of the audio signal receivers that receives the strongest audio signal, thereby outputting a corresponding movement signal to the driving mechanism. The automatically chargeable mouse is moved toward the audio signal receiver that receives the strongest audio signal according to the movement signal. | 04-15-2010 |
20100296548 | AUTOMATIC FREQUENCY HOPPING METHOD FOR USE WITH WIRELESS DEVICE - An automatic frequency hopping method is provided for use with a wireless device. The wireless device could transmit data in two or more communication frequency bands. According to the counts of successful data transmission in respective communication frequency bands, the reasons of communication failure are analyzed. According to the reasons of communication failure, the automatic frequency hopping method discriminates whether a frequency hopping procedure is performed. Since the frequency hopping procedure is performed when a proper frequency hopping condition is satisfied, the automatic frequency hopping method could achieve the power-saving purpose and avoid the wireless communication interference with other wireless devices. | 11-25-2010 |
20110082953 | DATA TRANSMISSION METHOD FOR USE WITH WIRELESS MOUSE - A data transmission method for use with a wireless mouse includes the following steps. Firstly, a mouse displacement data including a horizontal displacement and a vertical displacement is periodically transmitted from a wireless signal emitter to a wireless signal receiver in every wireless transmission time interval T | 04-07-2011 |
20110260971 | MULTI-FUNCTION MOUSE DEVICE - A multi-function mouse device includes a casing with a casing upper surface and a casing lateral surface, a first button disposed on the casing upper surface, a first sensing element, a second sensing element and a controlling unit. The first sensing element is disposed on the first button. The second sensing element is disposed on the casing lateral surface.
