| 20110153041 | CONNECTION SYSTEM - The connection system of the present invention includes a human-machine interface device and a host device. The human-machine interface device includes a signal generating module and a control module. The host device includes an operation module, an identification module and a system module. After the signal generating module generates an original working signal, the original working signal is sent to the operation module to generate a transforming signal via control module, and then the operation module sends the transforming signal back to the control module such that the control module generates a final working signal meeting an identification condition. Finally, the control module sends the final working signal to the identification module for identification such that the system module executes a predetermined work. | 06-23-2011 |
| 20110022858 | CONTROL CIRCUIT FOR POWER SUPPLYING - The control circuit for power supplying includes a driving module and a control module, wherein the driving module includes a first switch, a second switch, a third switch, and a fourth switch. In a first power supply mode, the first switch and the second switch are turned on, and the third switch and the fourth switch are turned off. The load current flows to the ground terminal via the first switch, the inductive load, and the second switch. When the control module sends a switching signal to the driving module, the first switch and the second switch are turned off and the third switch and the fourth switch are turned on, and the load current flows to the high potential terminal via the fourth switch, the inductive load, and the third switch due to the current inertia. | 01-27-2011 |
| 20090257740 | Switching Regulation Circuit and Dual-Winding Motor Apparatus - A switching regulation circuit for a dual-winding motor apparatus is provided. The switching regulation circuit comprises a gate-controlled device and a driving circuit. When one of the two windings generates an induced voltage signal greater than a threshold value, the driving circuit generates an output signal for turning on the gate-controlled transistor. Thereby, a parasitic diode of the gate-controlled device will not be turned on and damage the entire circuit. | 10-15-2009 |
| 20090179603 | Control Apparatus for Starting a Direct Current Brushless Motor and Method Thereof - An apparatus for starting a direct current brushless motor and a method thereof are provided. The direct current brushless motor comprises a plurality of windings. The control apparatus comprises a sense amplifier, a differential circuit, and a control circuit. The sense amplifier is configured to detect a first back electromotive force of a non-electrified first winding. The differential circuit is configured to calculate a differential value of the first back electromotive force. The control circuit is configured to provide a current to two of the windings and to switch the current to another two of the windings to start the direct current brushless motor. | 07-16-2009 |
| 20090174355 | Starting Apparatus for a Direct Current Brushless Motor and Method Thereof - A starting apparatus for a direct current (DC) brushless motor and a method thereof are provided. The DC brushless motor comprises a plurality of windings presenting a joint connection via a common connection. The starting apparatus provides current to two of the three windings and rotates the DC brushless motor to obtain a Back Electro-Motive Force (BEMF) from the floating winding. Then, the starting apparatus provides a current to another two windings to operate the motor according to the variation of BEMF induced by the swing of the motor when it rotates to a static equilibrium point. | 07-09-2009 |
| 20090167226 | Method for Controlling a Direct Current Brushless Motor, and Control Circuit - A method for controlling a direct current (DC) brushless motor, and a control circuit thereof are provided. The DC brushless motor is sensorless. In response to a digital output signal that is applied to drive the direct current brushless motor, detection of a back electromotive force (BEMF) is ceased in a predetermined time interval, so as to avoid detecting erroneous BEMF and keep normal operation of the direct current brushless motor. | 07-02-2009 |
