Abstract:
A pressure detecting apparatus made by 3D printing technologies being able to be used in dangerous areas is provided. It mainly comprises a light source, a processor, a coupler, and at least one pressure transducer. The pressure transducer comprises a main body and a fiber grating. The fiber grating comprises a fiber Bragg grating sensor, and the fiber grating is fixed on the main body and covers the fiber Bragg grating sensor. When the main body is placed in a fluid area, the fluid would flow through the opening to deform the strain layer and generate a strain variation on the fiber Bragg grating sensor to cause a signal variation in the reflection frequency spectrum. The coupler is configured to couple to the light source and the pressure transducer to decode the signal variation into pressure parameters.

Abstract:
A classified solar charging method defines four magnitude classes of charging current in accordance with a combination selected from four magnitude classes of power production of a solar cell and four magnitude classes of capacity of each rechargeable battery of a rechargeable battery pack. In addition to the optimal charging current, the method simultaneously takes an operating temperature of the rechargeable battery into account upon using the solar cell to store energy in the rechargeable battery. Accordingly, the present invention can selectively charge overall, partial or single rechargeable battery based on the power production of the solar cell and the capacity of the rechargeable battery to enhance a charging efficiency and reduce a charging time.

An ultrasonic motor includes a stator. The stator includes a seat and a driving unit. The driving unit includes a generally semi-elliptical driving mechanism formed integrally with the seat, and two spaced-apart piezoelectric actuators disposed between the seat and the driving mechanism. Each of the piezoelectric actuators has a first end abutting against the driving mechanism, and a second end opposite to the first end and abutting against the seat.
Abstract:
An automatic hold time fixing circuit unit includes a first switch having first and second ends connected to data input and output ports. An input end of a memory element is connected to the second end of the first switch. A second switch includes a first end connected to an output end of the memory element and a second end connected to the data output port. A control circuit includes first and second output terminals and first and second input terminals. The first and second output terminals are connected to control ends of the first and second switches. The first and second input terminals allow input of two clocks to the control circuit for controlling connection or disconnection of the first and second switches. The data stored in the memory element can be utilized to fix a hold time of the data, so that correct data can be obtained at the data output port.
Abstract:
For clearly identifying a product recorded in an image file provided by a client terminal, a method for identifying a remote pattern method is provided for preventing disputes between consumers and shopping websites. Such disputes are often caused when a conventional shopping website just searches products required by a consumer based on messages provided by the consumer. In the provided method, an image file of a required product of a consumer is identified by a customer service terminal for generating a plurality of keywords related to the required product. The keywords are then inputted into a database for searching. Detailed information about the required product is found according to search results. After the detailed information is examined by the customer service terminal, the examined detailed information is returned to the client at the client terminal.
Abstract:
A piezoelectric optical micro-switch structure includes a base unit, a first cantilevered arm base, a first piezoelectric controller, a second cantilevered arm base, a second piezoelectric controller and an optical reflector. The base unit bears the first cantilevered arm base and the second cantilevered arm base each of which has a first cantilevered arm and a second cantilevered arm. The first piezoelectric controller and the second piezoelectric controller are correspondingly attached to the first cantilevered arm and the second cantilevered arm and used to control bending angles of the first cantilevered arm and the second cantilevered arm. Connected between the first cantilevered arm and the second cantilevered arm is the optical reflector. When one of the first cantilevered arm and the second cantilevered arm is bent, the optical reflector can change a reflective direction of incident light.
Abstract:
A multi-functional geometric puzzle system includes four right-angled triangle pieces and two kite-shaped pieces. Each of the right-angled triangle pieces has an identical configuration, and each of the kite-shaped pieces also has an identical configuration. Each of the kite-shaped pieces is formed with four edges, and consists of two side right-angled triangles symmetric along-a longitudinal line. Each dimension of the side right-angled triangles is identical with that of the right-angled triangle piece. In assembling, all of the right-angled triangle pieces and the kite-shaped pieces can be selectively pieced up to generate various geometric patterns.
