Abstract:
A wiper head includes a cleanser-hosting pouch, a pulling-tab, an anti-leaking layer, and at least one wiper layer. The edges of the cleanser-hosting pouch are sealed for containing liquid cleanser therein, and a pull-tab is attached to a tear-able exit portion on one of the sealed edges. The cleanser-hosting pouch, the pulling-tab, and the anti-leaking layer are disposed between the first wiper layer and the second wiper layer. The anti-leaking layer, the first wiper layer, and the second wiper layer are joined together in forming at least one fixing portion for affixing to the cleaning device. The cleanser can be released from the cleanser-hosting pouch and infiltrates one of the wiping surfaces. The other wiping surface is used for drying the wetted floor or wall surface. Hence, the wiper head pocesses both wet and dry cleaning capabilities. The instant disclosure also provides a cleaning device utilizing the cleanser-hosting wiper head.
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 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:
