Abstract: A method for an electric nail gun to drive the flywheel to transmit nailing energy, including boosting a start voltage of a battery so as to excite an electromagnet to work and then drive the flywheel loaded with nailing energy in a frictional manner to drive a nailing rod to hit the nail. Specifically, the start voltage is boosted by a voltage boost circuit and stored, and the start voltage can release electric charge to constantly excite the electromagnet to work until completion of the nailing action. Based on the present invention, the nailing quality of the electric nail gun can be enhanced.

Abstract: A window cleaning machine includes a body, walking module, air extracting module, first cleaning device and driving device. The body defines a primary suction space. The walking module is disposed near the body. The air extracting module is disposed on the body and is in communication with the primary suction space, allowing the body to cling to the pane surface by suction. The first cleaning device is in contact with the pane surface while performing a cleaning operation. The driving device is connected to the first cleaning device to cause the first cleaning device to undergo a reciprocating motion so as to wipe the pane surface back and forth. The body further comprises a bottom board and a carrying board. The bottom board comprises a bottom board wall portion enclosing a first bottom board through hole. The carrying board is disposed between the first cleaning device and the bottom board.

Abstract: An antenna module includes two antenna units, two isolation members, and a grounding member. Each antenna unit consists of two feeding ends, two first radiators, and two second radiators. The isolating members are disposed between the first and second portions of each antenna unit. The grounding member is disposed beside the two antenna units and the two isolation members. A first slot is formed among each first radiator, the second radiator, and the grounding member. The two second radiators are connected to the third radiator. A third slot is formed between the second radiator and the second portion. The two antenna units are symmetric to the fourth slot in a mirrored manner, and the two first portions have widths gradually changing along an extending direction of the fourth position.

Abstract: A jacket for a handheld electronic device includes: a housing adapted to couple with a handheld electronic device; a fan mounted in the housing; and a control unit electrically connecting with the fan and adapted to electrically connect with the handheld electronic device, with the control unit capable of controlling the fan according to a control command outputted by the handheld electronic device.

Abstract: A motor casing includes a frame assembly and a motor base. The frame assembly includes a frame having an inner face defining an air channel, and a plurality of connection members disposed in the air channel. Each connection member has first and second ends. The first ends of the connection members are coupled to the inner face of the frame. The motor base includes a supporting member and a covering member. The supporting member has an inner surface defining a through-hole, and an outer surface coupled with the second ends of the connection members. An opening portion and a coupling portion are formed at two sides of the through-hole. The covering member is coupled to the opening portion of the supporting member and has first and second surfaces. The first surface faces the through-hole of the supporting member. The covering member includes at least one vent.

Abstract: A rotate-to-retract type storing apparatus including a U-shaped protective casing, a shell body and a storing arrangement. A disk member is protrudes adjacent to an open side at the surface of protecting casing, and a protrusion member is provided at a partial position of the disk member. The shell body defines a receiving cavity and includes an insertion hole at a front end thereof for a second end portion of the storing arrangement to get into the receiving cavity and a retention hole penetrating a bottom surface of the shell body for coupling with the disk member so that the shell body is capable of rotating with respect to the protective casing and directing the coupling slot to rotate with respect to the protrusion member. This defines a moving distance—just enough for a first end portion of the storing arrangement to move between an application position and a retraction position. The result is a minimized size of the storing apparatus.

The control unit is coupled to the motor driving circuit, generates a forward rotation command for controlling the motor to rotate in a predetermined direction when the control unit receives electrical power, and generates a backward rotation command for controlling the motor to rotate in a direction opposite to the predetermined direction when the control unit fails to receive the electrical power.

Abstract: A lamp includes a lighting module having a lighting element and a control circuit electrically connected to the lighting element. The lamp further includes a control unit having a temperature sensor and a processor electrically connected to the temperature sensor and the control circuit. The temperature sensor senses a temperature of the lighting element and generates a temperature sensing result. The processor controls brightness of the lighting element based on the temperature sensing result of the temperature sensor. Since the brightness of the lighting element can be controlled by the processor through the control circuit using the temperature sensing result, overheating of the lighting element during operation can be avoided. The service life of the lighting element is, thus, prolonged.
