Abstract: A video condensation & recognition method and a system thereof are used to detect objects in input frames, derive a 3D object trajectory from which one or multiple 2D trajectories with object tubes are extracted, and catch a time position that refers to non-overlapping condition of object tubes for rearrangement of several continuous object tubes and creation of a condensed video. The generated condensed video can be adjusted by the user in the range of longest detected object tube to the generated condensed video length that is very beneficial for video analysis process. Moreover, a searched attribute of an object in a condensed video is classified for the filtering process which is able to display an object correlated with a distinct searched attribute on the condensed video.

Abstract: A battery device includes a battery unit, a temperature port, a temperature sensitive component, a switch component and a battery management unit. The temperature sensitive component senses a temperature of the battery unit, and provides a temperature indication signal at the temperature port. The switch component is electrically connected to the temperature sensitive component. When the battery device operates abnormally, the battery management unit controls the switch component to make the switch component stop provision of the temperature indication signal at the temperature port.

Abstract: Provided is a control system and method for a power-driven nail gun, which includes a battery, a motor, a flywheel rotating along with the motor, an impacting member receiving kinetic energy of the flywheel and a nail channel providing a channel for a nail to move along therewith when hit by the impacting member. The method includes utilizing a microcontroller to provide a pulse width modulation (PWM) signal for a driving circuit to drive the motor based on the PWM signal; and in response to reaching a target rotation speed by the motor, utilizing the microcontroller to output a corresponding PWM duty to the driving circuit based on the voltage of the battery, to make the motor maintain at the target rotation speed. The nails obtain stable and consistent kinetic energy and stability of nail firing is effectively improved.

Abstract: A method for controlling a nail-striking operation of an electric nail gun is proposed. The electric nail gun includes a control module and at least one switch. The at least one switch outputs a first switch signal that has a first voltage and a second switch signal that has a second voltage when triggered. The control module set a flag that corresponds to the at least one switch to a predetermined state upon determining that a striking condition is met. The striking condition includes that, for each of the at least one switch, the first switch signal has the first voltage and the second switch signal has the second voltage.

Abstract: A return device includes a return wheel unit adapted to be mounted to a gun body of a fastening tool, and including a return wheel that is movable between a free position, where the return wheel is not in contact with an impact member of the fastening tool, and a return position, where the impact member is at a strike position and is not contact with a rotatable flywheel of the fastening tool, and where the return wheel is in contact with the flywheel and the impact member such that, when the flywheel rotates in a first rotational direction, the return wheel is driven by the flywheel to rotate in a second rotational direction opposite to the first rotational direction, and moves the impact member from the strike position to a standby position.

Abstract: A securing module includes a positioning member, a fixing member, a wire management member, and a cover. The positioning member is disposed on a case. The fixing member is passed through the positioning member and fixed to the case. The wire management member is disposed on the fixing member. The cover is assembled to the case. The cover includes at least one hook, a clamping component, and a hollow shell. The at least one hook and the clamping component are disposed on the hollow shell. The hollow shell covers the positioning member, the fixing member, and the wire management member. The clamping component is selectively moved between a fixing position and a releasing position. When the at least one hook is snap-fit to the case and the clamping component is located at the fixing position, the clamping component clamps the positioning member so that the hollow shell is fixed to the case.

The plurality of actuators comprises first actuator, second actuator and third actuator for actuating the outer shell, the middle shell and the inner shell, respectively. The first actuator, the second actuator and the third actuator are connected to one of the at least one casting/frame or one of the three spherical shells.

Abstract: A heat dissipating device includes a base, a heat pipe and a fixing member. The base includes an accommodating recess and two restraining portions, wherein the two restraining portions are located at opposite sides of the accommodating recess and an opening is between the two restraining portions. A first end of the heat pipe is disposed in the accommodating recess such that a bottom surface of the first end is exposed out of the opening, wherein a width of the opening is smaller than a maximum width of the first end. The fixing member is disposed on the base such that the first end of the heat pipe is fixed between the fixing member and the two restraining portions.
