| 20090160655 | EYE PROTECTION APPARATUS - An eye protection apparatus includes a sensor adapted for sensing the presence of a person within a predetermined distance range in front of a monitor and outputting a pulse signal, an amplifier unit connected to the sensor for receiving the pulse signal and outputting an amplified signal, a comparator connected to the amplifier unit to receive the amplified signal, a MPU connected to the comparator, and an alarm circuit connected to the MPU. The comparator compares the amplified signal with a predetermined signal, and sends a result to the MPU; the MPU outputs a control signal according to the result to the alarm circuit, and the alarm circuit controls power to the monitor. | 06-25-2009 |
| 20090183012 | KEYBOARD - A keyboard includes a keyboard processor configured for outputting a control signal for turning a computer on/off; a switch circuit connected to a turn-on port of a south bridge chipset on a mainboard of the computer; and a processor connected to the keyboard processor and the switch circuit. When the processor receives the control signal output from the keyboard processor, the processor outputs a high pulse signal to the switch circuit to make the turn-on port grounded to turn on or turn off the computer. | 07-16-2009 |

| 20080267415 | PORTABLE ELECTRONIC DEVICE - A portable electronic device includes a player, a speaker, a control circuit, a switch circuit, and a current limiter. The player is for outputting analog audio signals. The speaker is for transforming the analog audio signals into sound. The control circuit is for generating a first control signal when ambient light intensity is lower than a predetermined value. The switch circuit is for turning on and transmitting the analog audio signals to the speaker when receiving the first control signal. The current limiter is for transmitting the analog audio signals to the speaker when the switch circuit turns off, and for limiting a current flowing through the speaker. | 10-30-2008 |
| 20090052653 | TELEPHONE DEVICE, TELEPHONE LINE MONITORING DEVICE AND METHOD - A telephone line monitoring device is connected to a telephone line and adjacent to a telephone device using the telephone line. The telephone line monitoring device includes a rectifying circuit for generating a corresponding direct current voltage according to an effective voltage of the telephone line; a first controller for generating a first control signal when the direct current voltage is lower than a predetermined voltage; a second controller for detecting an operating state of the telephone device and generating a second control signal when the telephone device is operated; a load booster for pulling down the effective voltage of the telephone line when enabled; and a first switch circuit for disabling the load booster whenever receiving the second control signal, and enabling the load booster when receiving the first control signal while not receiving the second control signal. A monitoring method and a telephone device are also provided. | 02-26-2009 |
