Abstract: A method for touchless gesture recognition is provided. The method includes transmitting ultrasonic signals via a speaker. The method includes generating ultrasonic signals. The method includes receiving the reflected ultrasonic signals from an object via two or more microphones. The method includes computing a frequency shift according to the reflected ultrasonic signals. The method includes identifying a gesture that corresponds to a movement of the object according to the frequency shift. The method includes performing a function that corresponds to the gesture.

Abstract: Disclosed is an upside-down sprayer with an auxiliary air conducting device for liquid pumping, including a container, a nozzle, and a dip tube equipped with a switching valve near its upper end, which has a valve casing, a valve ball, and an inverted liquid pumping port. An auxiliary air conducting device is disposed adjacent to the switching valve and includes a connection part, a guide seat, and a projecting tube with an opening, wherein the connection part is positioned on the dip tube, the guide seat has a groove, and the projecting tube communicates with the groove. The opening of the projecting tube is offset in the direction of the inverted liquid pumping port, and the height of the opening is not lower than the height of the inverted liquid pumping port when used inverted.

Abstract: A semiconductor package includes a first die comprising an upper surface and a lower surface opposite to the upper surface. The first die includes a plurality of through-silicon vias (TSVs) penetrating through the first die. A second die is stacked on the upper surface of the first die. An interposer layer is disposed on the lower surface of the first die. An inductor is disposed in the interposer layer. The inductor comprises terminals directly coupled to the TSVs.

Abstract: A transparent plastic integrally molded goblet has a cup-shaped part, a columnar first leg and a disc-shaped first base integrally molded from transparent plastics. The bottom edge of the cup-shaped part extends downwards to form the first leg. The bottom end of the first leg integrally forms the first base. The cup-shaped part has a circumferential wall which encloses the circumference of a first space. The top edge of the circumferential wall forms an annular first ring frame, and the central part of bottom edge of the first base downwards forms a first convex pin. The integral molding of transparent plastics can enhance the appearance integrity of the goblet, the manufacture of the goblet is easy and the product yield is increased.

Abstract: A motor system includes at least two motors respectively having an output power and a rotary shaft, wherein at least one coupling is provided to connected the at least two rotary shafts. A detect unit is electrically connected to each of the at least two motors and detects the currents of the at least two motors and forms detecting signals relative to the current value of each of the at least two motors. A control unit is electrically connected to the at least two motors for receiving a controlling signal and the detecting signal for adjusting an output power to the electric actuator.

Abstract: A liquid soap dispenser includes a cap adapted to be mounted onto a container. A cylinder longitudinally and rotatably extends through the cap. A tube is longitudinally connected to a lower end of the cylinder. A discharge tube is partially longitudinally received in the cylinder. The discharge tube has a lower end received in the cylinder and abutting against an inner periphery of the cylinder and is reciprocally moved relative to the cylinder. A push-button is mounted onto a top of the discharge tube. A negative pressure relative to the space in the container is intermittently formed in the cylinder such that the liquid soap in the container will sequentially pass through the tube, the discharge tube and the push-button when the push-button is reciprocally pressed and the piston of the discharge tube is reciprocally moved relative to the cylinder.

Abstract: A self-learning method for keyword based human machine interaction is disclosed. At least one of a plurality of keywords predetermined in a database is selected and a priority score of the selected keyword is updated and a weighted factor is generated for the selected keyword. A weighted score and the weighted factor of the selected keyword are transmitted to the keywords related to the selected keyword. The selected keyword is pushed to a keyword buffer and linkage strengths between the keywords in the keyword buffer are strengthened. When a keyword has been stored in the keyword buffer for over a predetermined reset time period, a reset operation is performed to remove the keyword from the keyword buffer.

Abstract: A processing method for a portable navigation device equipped with a conversation system is disclosed. When the portable navigation device is operating in a dumb mode, events are displayed on a screen of the device according to preset conditions and parameters. In a normal mode, events scheduled in the 1st to Xth order are pushed to the user according to preset conditions, and, in a hype mode, events are displayed on the screen based on preset conditions and parameters while events residing at the top layer of the screen are actively and repeatedly pushed to the user.
