Abstract:
A detecting device is used to detect the connection of an electronic device. The detecting device includes a circuit board and a connector module. The circuit board includes a power terminal and a signal processing unit. The connector module includes a body and a detecting member. The body has a connecting port and a connecting sidewall. The detecting member is disposed on the connecting sidewall and electrically connected to the power terminal and the signal processing unit, and it has a potential. When a plug of the electronic device is connected to the connecting port, the plug contacts the detecting member to change the potential. The change of the potential is detected by the signal processing unit such that the connection between the electronic device and the connector module is confirmed.
Abstract:
A cooling apparatus for an electric motor includes a mount to be fixed to and abutted against the electric motor, and a cooling unit installed to the mount. The mount defines at least two channels. The cooling unit connects adjacent said at least two channels to form a passage to allow a cooling fluid flowing in the passage.
Abstract:
A motion control servo loop apparatus, comprising: a feed-forward control module, and a proportional-integral-derivative (PID) control loop and a compensation adder. The feed-forward control module is capable of generating a feed-forward compensation. The PID control loop further comprises: a proportional control module, an integral control module and a derivative control module. The proportional control module is capable of generating a proportional compensation. The derivative control module is capable of generating a derivative compensation. The integral control module uses a digital differential analyzer (DDA) algorithm to perform integration for accumulated errors with respect to each sampling clock at each DDA pulse and thus output an accumulated error, which is then processed to generate an integral compensation. Thereafter, the compensation adder receives the feed-forward compensation, the proportional compensation, the integral compensation and the derivative compensation to calculate a position error compensation for a motor driver.
Abstract:
A water-cooled heat dissipation device for a notebook computer includes primarily a pad and a heat dissipation device at a bottom of the pad having an air through-hole. The heat dissipation structure has a fan below a U-shape plate, a groove of which is latched with parallel fins being transfixed with a metallic tube in a detouring way, with two ends of the metallic tube being connected to a water pump, allowing cooling water to circulate in the metallic tube to cool down the fins. The heat dissipation structure is fixed below the air through-hole of the pad with the two ends of the U-shape plate. In usage, a notebook computer is put on the pad, and temperature of the notebook computer is conducted to the pad. Furthermore, cold wind is blown to the pad by the fan, such that the notebook computer can be cooled down rapidly.
