| 20080264996 | Trigger Valve for Pneumatic Nail Gun - A nail gun includes an air concentrating chamber and a main air passage, and the trigger valve is disposed between the air concentrating chamber and the main air passage. The trigger valve includes a valve body, a shuttle valve nested in the valve body, a valve base integrated with the valve body, and a valve bar being capable of pressed and released. When the valve bar is pressed to actuate the high pressure air in the air concentrating chamber to drive the shuttle valve to downwardly move, for guiding the high pressure air in the air concentrating chamber into the main air passage to provide necessary energy for hitting nails. When the valve bar is released, the high pressure air in the main air passage are exhausted, so as to actuate the high pressure air in the air concentrating chamber to drive the shuttle valve to upwardly move to reposit. | 10-30-2008 |
| 20080290131 | Main Valve Driving Air Passage of Nail Gun - An air passage of a nail gun includes a fixed cylinder disposed in a gun body, and a main valve disposed at a top portion of the fixed cylinder, a trigger valve between an air collecting chamber and a main passage, an air-in passage formed in the trigger valve connecting between the air collecting chamber and the main passage, an air-out passage formed in the trigger valve connecting between the main passage and external atmosphere, and a disc-shaped valve stopper forming a main chamber. The main chamber collects the high pressure air via the air-in passage to actuate the valve stopper to move up while the valve bar is pressed, and exhausts the high pressure air in the main chamber via the air-out passage to actuate the high pressure air in the air collecting chamber to drive the valve stopper and the main valve to move down to reposit while the valve bar is released. | 11-27-2008 |
| 20090032566 | Transmission Mechanism for Electrical Nail Gun - A transmission mechanism for an electrical nail gun includes a rotary transmission unit and a linear transmission unit in a housing of the electrical nail gun. The rotary transmission unit includes a motor driven by electricity, a flywheel driven by the motor and extending to form a cylinder thereon, a solenoid activated by electricity, and a moveable driving wheel adjacent to an end side of the cylinder. A clutch is formed between the cylinder and the driving wheel. The solenoid is buried in the cylinder so that a magnetic conductivity loop is constructed around the solenoid to produce the magnetic field when the solenoid is activated. The driving wheel is attracted to move to an engagement position to be driven by the flywheel, thereby driving the linear transmission unit to impact a nail when the solenoid is activated by electricity, and the driving wheel returns to a disengagement position to disengage from the flywheel, thereby stopping driving the linear transmission unit when the solenoid is demagnetized. | 02-05-2009 |

| 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 |
