| 20090219965 | POWER-SAVING LASER POINTER MOUSE - The present invention provides a power-saving laser pointer mouse including a battery, a micro-controller and a laser diode. The power-saving laser pointer mouse can be operated in multi-stage power-saving modes according to the voltage value of the battery. The lighting time interval of the laser diode is adjusted by the micro-controller according to the voltage value of the battery. When the voltage value of the battery is reduced, the lighting time interval of the laser diode is shortened so as to achieve the power-saving purpose. | 09-03-2009 |
| 20090190621 | Laser Turn-On Accelerator Independent of Bias Control Loop Bandwidth - An accelerator circuit is incorporated in a laser diode system for accelerating the turn-on operation of the laser diode independent of the control loop bandwidth of the laser diode system. The accelerator circuit provides a boost current to a compensation capacitor upon laser turn-on which compensation capacitor operates to establish the control loop bandwidth of the laser diode system. The boost current enables the control loop to increase the bias current to the laser diode quickly. When the laser diode reaches the desired operating point, the boost current is terminated and the control loop of the laser diode system resumes normal control of the bias current. In one embodiment, the accelerator circuit includes a timer circuit controlling a current source to implement open loop turn-on control. In another embodiment, the accelerator circuit includes a comparator circuit working in conjunction with an one-shot logic circuit for providing close loop control. | 07-30-2009 |
| 20100226398 | Systems and Methods for Upgrading Non-Compliant Laser Devices - An assembly for use with a non-compliant laser device comprising the combination of an emission indicator assembly configured to indicate the actuation of the non-compliant laser device, a key control assembly configured to selectively provide electrical continuity throughout the circuitry of non-compliant laser device, and a remote interlock assembly configured to selectively provide for remote control of the non-compliant laser device and provide electrical continuity throughout the circuitry of non-compliant laser device. | 09-09-2010 |
| 20090168822 | LASER CONTROL APPARATUS AND ELECTRONIC DEVICE USING THE SAME - A laser control apparatus includes a detector and a switch module. The detector is for detecting states of a mechanism having a closed state in which the mechanism blocks a laser and an opened state in which the mechanism unblocks the laser. The switch module is for transmitting an emitting command to a laser unit to emit the laser. When the opened state is detected, the switch module stops transmitting the emitting command. An electronic device using the laser control apparatus is also disclosed. | 07-02-2009 |
