Abstract: An electrostatic sensing system configured to sense an electrostatic information of a fluid inside a fluid distribution component and including an electrostatic sensing assembly, a signal amplifier and an analog-to-digital converter. The electrostatic sensing assembly includes a sensing component, and a shield. The sensing component is configured to be disposed at the fluid distribution component. The sensing component is disposed through the fluid distribution component so as to be partially located in the fluid distribution component. The shield surrounds a part of the sensing component that is located in the fluid distribution component. At least part of the shield is located on an upstream side of the sensing component. The signal amplifier is electrically connected to the sensing component. The analog-to-digital converter is electrically connected to the signal amplifier. The shield has an opening spaced apart from the sensing component.

Abstract: A face recognition system based upon a facial motion including an image capturing device, a storage device and a processing unit. The storage device stores facial information of an intended user. The facial information contains data of the intended user's facial feature and is associated with a binding operation. The image capturing device captures a facial video clip where a user makes a series of facial expressions over a time frame. The facial video clip of the user contains image frames. The processing unit extracts at least one facial feature of the user from the image frames and calculates the variation of that over the time frame. The processing unit compares the variation of the facial feature of the user with the facial information of the intended user. If the deviation between them falls within a threshold, the processing units goes on to perform the binding operating.
