  • Power tool electronics
    Patent number: 10305307
    Abstract: A battery waking circuit and a battery leakage circuit are provided. The battery waking circuit includes a first battery pack and a second battery pack connected in series and a first switch connected to the first battery pack along a first current path. An electronic controller coupled to and controlling the first switch is configured to close the first switch based on detecting a trigger actuation to draw a wake-up current on the first current path from the first battery pack. The electronic controller is also configured to control a motor to draw a load current along a second current path after the first battery pack is woken up. The battery leakage circuit also includes a switch connected in series with the capacitor and a trigger switch controlling the switch such that the switch prevents a flow of leakage current through the capacitor when the trigger is not actuated.

  • Tool bit holder
    Patent number: 10286456
    Abstract: A tool bit holder for connecting a rotary tool to a rotary tool driver. The tool bit holder including a body having a driver end configured to connect to a rotary tool driver and a tool end, a tool retainer bore, and a tool retainer movably received within the tool retainer bore and movable between an engaged position and a retracted position. The tool bit holder further includes an actuator sleeve, a sleeve spring for urging the actuator sleeve towards a first position, a plunger, and a plunger spring urging the plunger towards a loading position. A tool bit received in a tool receiving cavity pushes the plunger to a loaded position, and in the loading position the plunger extends over the tool retainer bore to engage the tool retainer and urge the tool retainer towards the retracted position.

  • Oscillation and Retraction Mechanism for Window Blinds
    Publication number: 20190128060
    Abstract: A window covering assembly includes a plurality of slats held by a ladder that extends between a header and a bottom rail. The bottom rail is suspended from a suspension cord that is attached to the header. An oscillation and retraction mechanism tilts and retracts or extends the blinds. The same components are used in both a tilting operation and a retraction or extension operation. An actuator is provided that selectively causes the oscillation and retraction mechanism to either tilt the slats or to retract or extend the slats.
