Abstract: A sensor using ultrasound to detect presence and nature of analyte includes an ultrasonic element and a receptor thereon. The ultrasonic element includes a first electrode, a second electrode facing and spaced apart from the first electrode, an insulating layer between the first electrode and the second electrode, and a vibrating film between the insulating layer and the first electrode. The vibrating film carries the first electrode. A cavity is formed between the vibrating film and the insulating layer. The receptor is on a side of the first electrode away from the second electrode. The receptor can combine with a target substance in a test analyte. When the first electrode and the second electrode are applied with different voltages, certain ultrasound frequencies are generated as the vibrating film vibrates, and the presence and weight of different target substances are indicated by the changes in resonance.

Abstract: An electrical connector assembly includes an electrical connector and a paddle card. The electrical connector has a terminal assembly, and the paddle card has a main body, a plurality of contacting pads, and a grounding strip pad. The main body has a first surface, a second surface, a front edge, and a rear edge; a plurality of contacting pads disposed on the main body. The contacting pads are correspondingly connected to the terminal assembly. A plurality of first-group soldering pads are disposed on the first surface. A plurality of second-group soldering pads are disposed on the second surface. A pair of positioning concaved-portions are respectively disposed at two sides of the paddle card closed to the rear edge. The grounding strip pad is formed on the paddle card in a traverse manner, and has two ends extending to the pair of positioning concaved-portions.

Abstract: An electrical connector is provided. The electrical connector includes an insulating housing, an adaptor board, and a plurality of terminals. The insulating housing has a plurality of slots, a plurality of terminal holes, and an inserting recess. The terminal holes are formed on an inner sidewall of the inserting recess. The adaptor board disposed on the insulating housing includes a plurality of first conductive portions and a plurality of notches formed at one side of the adaptor board. The terminals are respectively accommodated in the slots of the insulating housing. Each of the terminals has an elastic portion and a contacting portion. Each of elastic portions of the terminals can be engaged with each of notches and electrically connected to each of the first conductive portions. The contacting portions of the terminals respectively pass through the terminal holes and protrude from the inner sidewall of the inserting recess.

Abstract: A bathtub includes an integrally formed rectangular body with a recess having an appropriate depth. The four corners of the body are formed with four cylindrical holes. The bathtub is provided with positioning indents on the surface of the recess for fastening a shaped pad therein. The shaped pad, which is molded according to the shape of a baby, can be used to prop up a baby for washing. When the pad is removed, the bathtub can be used to wash a bigger baby. The space inside the bathtub can also be used as a parcel barrel. The cylindrical holes on the four corners can be inserted with legs of different length in order to lift up the bathtub for the ease of an adult to wash a baby. Alternatively, the legs can be inserted in the opposite direction and the bathtub can be upside down so that the construction can be used as an end table or a study desk, etc.
