Abstract: An electric motor control circuit for selectively connecting and disconnecting a pair of input terminals of an armature of an electric motor to a source of electrical power to selectively brake and reverse the rotation of the armature. Switching means associated with the control circuit directs current to a first terminal of the armature to cause a selected direction of rotation and when braking is desired the first terminal is disconnected from the power source, while the second of the armature terminals is grounded directly or through a resistor to provide a dynamic braking without the application of an external voltage being applied across the pair of terminals of the armature. The switching means is so arranged that neither terminal of the armature can be prematurely grounded during the braking or reversing operations.

Abstract: A motor controller comprises a switch circuit, a control circuit, and a function pin. The switch circuit is coupled to a motor for driving the motor. The control circuit generates a plurality of control signals to control the switch circuit. The function pin is coupled to the control circuit for receiving a function signal. The function signal is configured to inform the motor controller to execute a braking function. The braking function enables a braking time to be a variable value.

Abstract: A power tool, in particular an electric screwdriver, includes (i) a housing; (ii) an electric motor which is located in the housing and by way of which an insert tool located in a tool holder can be rotationally driven; (iii) and a control device which is designed to control a braking process of the electric motor in response to a braking request in order to stop the rotating insert tool. The braking process includes countercurrent braking. A method for braking an electric motor of a power tool, a computer program, and a machine-readable storage medium are also disclosed.

Abstract: A fan brake circuit includes a semiconductor switch unit, a motor, a motor drive circuit, an isolation unit, a charging/discharging unit and a control unit. One end of the motor, the semiconductor switch unit and the control unit serves to receive an input power. When the fan is powered off, the semiconductor switch unit disconnects from the motor and the motor drive circuit receives the operation voltage provided by the charging/discharging unit and transmits the drive signal to the motor, whereby the motor forms a short-circuit to brake. By means of the design of the fan brake circuit, when the fan is powered off, the fan can quickly brake and stop and the cost is lowered.

Abstract: An automated aerial vehicle (AAV) and system for automatically detecting a contact or an imminent contact between a propeller of the AAV and an object (e.g., human, pet, or other animal) are described. A safety profile for the AAV may be selected based on various factors including a position or configuration of the AAV. When a contact or an imminent contact is detected, the selected safety profile may be executed to reduce or avoid any potential harm to the object and/or the AAV. For example, if a contact with a propeller of the AAV by an object is detected, the rotation of the propeller may be stopped to avoid harming the object. Likewise, an object detection component may be used to detect an object that is nearing a propeller, stop the rotation of the propeller, and/or navigate the AAV away from the detected object.

Abstract: A touch control arrangement is arranged for a container having a foldable cover being folded between an opened position and a closed position via an actuation unit. The touch control arrangement includes a power source and a touch actuator electrically linked to the power source, wherein the touch actuator is located out of the storage cavity of the container body and is arranged in such a manner that when the touch actuator is activated by a presence of a touch, the actuation unit is actuated to move the foldable cover from the closed position to the opened position.
