20100031072 | SYSTEM FOR POWER MANAGEMENT AND SAFETY PROTECTION AND METHOD THEREOF - A system for power management and safety protection and a method thereof are presented. The system and method are applicable to a computer device having a sensor. The sensor detects position information of a user relative to the computer device so as to determine whether to enter a sleep mode or a recognition mode. The sensor also detects motion information of a particular motion of the user so as to return to an operating mode. | 02-04-2010 |
20100125343 | Complex Servo Control System - A complex servo control system includes a host control end, a servo master controller, and a plurality of servo streams. The host control end sends control commands, and the servo master controller receives the control commands to generate corresponding control signals. Each control signal includes an identification code and a setting value. The servo streams are electrically connected to the servo master controller in parallel. Each of the servo streams includes a plurality of servos and each of the servos has a given an identification code. The servo master controller sends the control signals to one of the servo streams according to the identification code carried by the control signals, and the control signals are then received and sent downwards in sequence by the servos of the servo stream. When the identification code carried by control signals match the given identification code of one of the servo, the servo having the identification code activates according the setting value. | 05-20-2010 |
20110295447 | DIRECTION DEVICE AND OPERATION SYSTEM UTILIZING THE SAME - A direction device controlling a traveling route of a cleaning robot and including a receiving unit, an emitting unit and a control unit is disclosed. The receiving unit receives an encoded ultrasonic wave emitted by the cleaning robot. The emitting unit emits at least one wireless signal.

The method includes steps of moving the cleaning robot according to a first direction; keeping moving the cleaning robot according to the first direction when a light detector of the cleaning robot detects a light beam; moving the cleaning robot for a predetermined distance and then stopping the cleaning robot when the light detector does not detect the light beam; and moving the cleaning robot in a second direction. | 08-22-2013 |
20140195050 | CLEANING ROBOT AND SYSTEM UTILIZING THE SAME - A cleaning robot is disclosed. A first sensing unit generates a sensing signal to a transmittal line according to an external wireless signal. When the external wireless signal is sensed by the first sensing unit, a state of the transmittal line does not match with a pre-determined state. When the external wireless signal is not sensed by the first sensing unit, the state of the transmittal line matches with the pre-determined state. A control unit generates a movement signal when the state of the transmittal line matches with the pre-determined state. A plurality of wheels rotate according to the movement signal. A second sensing unit generates a second sensing signal according to the external environment of the cleaning robot. When the state of the transmittal line does not match with the pre-determined state, the control unit adjusts the movement signal according to the second sensing signal. | 07-10-2014 |
