A power tool is provided including a brushless DC (BLDC) motor, a rectifier that receives an alternative current from a power supply and outputs a rectified signal supplied to a DC power bus, and an inverter circuit having motor switches connected electrically between the DC power bus and the motor. A control module controls a switching operation of the power switches to regulate supply power from the power supply to the motor. The control module controls the switching operation so as to, within a half cycle of the AC power supply voltage waveform, increase current draw from the power supply from a first threshold at or after a first zero-crossing of the half cycle up to a second threshold, and reduce current draw from the power supply from the second threshold up to a third threshold at or prior to a second zero-crossing of the half cycle.

A control pod includes a controller to control an environmental condition in a space, and a cover plate covering the controller and having a light transmissive area extending along a substantial section of an outer perimeter of the cover plate. Programming configures a processor to detect user inputs of a control command based on a user action detected via user input response sensors, and based on the detected control command, send a control signal to a device to implement a function corresponding to the detected control command. The processor also controls a light source to selectively provide a light output through the light transmissive area of the cover plate for a period of time following the control command detection, as visible feedback corresponding to the detected control command, for observation by the user, along at least a portion of the section of the light transmissive area of the cover plate.

A power tool is provided, including a housing; a brushless DC (BLDC) motor arranged within the housing, the motor including a stator and a rotor rotatably disposed within the stator; a power module electrically disposed between the motor and a power supply, the power module including power switches; an actuator engageable by a user; and a control module configured to control a switching operation of the power switches to begin supply power to the motor when the actuator is engaged. The control module monitors engagement and disengagement events of the actuator, and ignores a subsequent engagement of the actuator if at least one of number of actuator engagement events and/or number of actuator disengagement events exceeds a predetermined threshold value within a predetermined time.

Sensorless thermal protection for power tools

A technique is directed to launching an unmanned aerial vehicle (UAV). The technique involves attaching a UAV launcher to a hand-held weapon, and installing a UAV onto the UAV launcher while the UAV launcher is attached to the hand-held weapon. The technique further involves activating the hand-held weapon to launch the UAV into flight from the UAV launcher. Since a user already may be carrying the hand-held weapon for firing ammunition, the user simply needs to further carry the UAV launcher and the UAV which, in some situations, can be packaged into an easy-to-carry container such as a backpack, a carrying case, and so on.
