Abstract: An antenna rotation structure includes a rotating shaft member rotatably disposed through a perforated groove of a housing, an annular member, and an elastic member. The rotating shaft member has a holding portion located in an accommodating space of the housing, a connecting portion connected to the holding portion and with an annular groove, and a gripping portion with one end connected to the connecting portion and the other end protruded from the housing. The annular member is disposed in the annular groove and abuts the perforated groove. The elastic member is sleeved on the one end of the gripping portion. The connecting portion and the one end of the gripping portion are disposed in the perforated groove. The gripping portion is turned to drive the rotating shaft member to rotate, thereby adjusting an angle of the antenna.

Abstract: A marking method on image combined with sound signal, a terminal apparatus, and a server are provided. In the method, a first image is displayed. A selection command is detected. A target sound signal is embedded into a speech signal so as to generate a combined sound signal. The combined sound signal is transmitted. The selection command corresponds to a target region in the first image, and the selection command is generated selecting the target region through an input operation. The target sound signal corresponds to the target region of the selection command, and the speech signal is obtained by receiving sound. Accordingly, all attendants in the video conference are able to make makings on a shared screen.

Abstract: Antenna rotation structure includes a rotating member and an angle adjusting member. The rotating member is rotatably disposed along an axial direction in an accommodating space of the housing and includes a holding portion and a pushing portion disposed at one side of the holding portion spaced apart from the axial direction. The angle adjusting member includes a pressing portion bonded to a through hole of the housing and made of an elastic material and, an abutting portion connected to the pressing portion and corresponding to the pushing portion. When the pressing portion is pressed by a force, it deforms and drives the abutting portion to push the pushing portion to drive the holding portion to rotate about the axial direction to adjust the angle of the antenna.

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.
