Abstract: A watch winder includes a housing, a power supply disposed in the housing, a transmitter coil mounted at one side of the housing and electrically connected with a circuit board of the power supply, and a receiver coil mounted at another side of the housing and electrically connected with a circuit board of the power supply. The fist coil can be actuated by the power supply to transmit a signal, and the receiver coil can be used to receive a signal and convert the signal into an electrical current that can be transmitted to the circuit board for charging the power supply. Therefore, the electrical energy of the watch winder can be wireless transmitted through a non-contact interface.

Abstract: A fountain lamp includes a housing having a bottom inlet, a pump unit mounted inside the housing for pumping a fluid from the inlet into a delivery pipeline, a light emitting device mounted in the housing for controllably emitting light out of the housing, a control unit for controllably driving the pump unit and the light emitting device, and a shifting unit having a base mounted in the housing and having a through hole connected to the delivery pipeline and a spray-pattern dial rotatably mounted in the base. The spray-pattern dial has multiple chambers, multiple guide holes respectively connected to the chambers and selectively set in communication with the through hole, and multiple sets of outlets respectively connected to the chambers for selectively exit of the fluid from the chambers and the housing for different fluid spray patterns.

Abstract: Composition of digits and method of digit display for digital clocks involve implementing seven main segments, which are ranked as two linked squares sharing a common edge wherein the main segments further enclose two transitional display areas and displaying a plurality of sub-segments in succession fleetingly to constitute a continuous action for connecting a digit with a latter digit until the main segments of the successive digit are completely displayed.

Abstract: A dust-collecting auxiliary device is equipped on a vacuum cleaner that comprises at least a motor, a fan, a dust-collecting chamber, a suction inlet, and a driving device. Said dust-collecting auxiliary device includes at least one air pipe of which an air inlet at one end is fixed in a fan container of said fan and an air outlet is placed at the lower surface of the bottom cover of the vacuum cleaner in to the neighboring-front the suction inlet, at least two wings wherein each wing with one end fixed at the one side of the suction inlet, while the other end thereof extended forward and outward to give an increasing distance from another wing.

Abstract: A dart and dartboard set, which includes a dart, which is a plastic dart with a flat magnet at the front end, and a dartboard, includes a front fabric panel printed with a score, ring pattern, a back fabric panel, two induction circuit membranes separated by a flexible magnet panel and packed between the front fabric panel and the back fabric panel, and a control circuit board for counting and displaying the score.

Abstract: A controller electrically connected to a keyboard consisting of a set of white keys and black keys through a flexible ribbon cable for controlling the operation of the keyboard is disclosed to include an external operating interface, which has a speaker, a display, and a set of operating buttons respectively mounted on a cover shell thereof, and an internal control unit, which is mounted outside the cover shell of the external operating interface and has a microprocessor, a memory, and a power unit. The microprocessor has an input side electrically connected to the flexible cable and the operating buttons of the external operating interface, and an output side electrically connected to the speaker and the display. The memory is electrically connected to the microprocessor and controlled by the microprocessor for data access. The power unit provides the microprocessor with the necessary working voltage.
