Patent number: 11569765Abstract: A system is provided with a set of removable battery packs and a set of power tools each including a motor, a controller, and a battery receiving portion. For each power tool, the controller is configured to identify a type of battery pack coupled to the battery receiving portion and limit a maximum amount of electric current drawn from the battery pack by the motor based on the identified type of the battery pack. The greater a ratio of an impedance of the motor to an impedance of the battery pack, the less the controller limits the maximum amount of electric current drawn from the battery pack such that for a given battery pack of the set of removable battery packs, the lower the impedance of the motor, the more current the motor draws from the given battery pack.Type: GrantFiled: October 9, 2020Date of Patent: January 31, 2023Assignee: Black & Decker Inc.Inventors: Christopher W.

Patent number: 9722525Abstract: A protective redundancy circuit is provided for a power tool having an electric motor. The protective redundant subsystem is comprised of: a motor switch coupled in series with the motor; a motor control module that controls the switching operation of the motor switch; and a protective control module that monitors switching operation of the motor switch and disables the power tool when the switching operation of the motor switch fails. In the context of an AC powered tool, the switching operation of the motor switch is correlated to and synchronized to the waveform of the AC input signal. During each cycle or half cycle, the motor control module introduces a delay period before closing the motor switch and the protective control module determines the operational status of the motor switch by measuring the voltage across the motor switch during the delay period.Type: GrantFiled: June 19, 2015Date of Patent: August 1, 2017Assignee: Black & Decker Inc.Inventors: John C. Vanko, Larrry T. Albert, Michael K. Forster, Bhanuprasad V. Gorti, Jason K. Leh, Garrett P. McCormick, Samuel G. Woods, David R. Beers

Patent number: 9225275Abstract: A power tool including a motor, light unit, and switch unit for selectively connecting the motor and light unit to a power source. A control module includes a controller coupled to a first electronic switch to control power delivery to the motor based on a position of the switch unit, and to a second electronic switch to control power delivery to the light source based on a position of the switch unit. A timer is configured to keep the light unit illuminated for a predetermined amount of time after the switch unit has been activated or deactivated. The control module also includes a boot circuit with a semiconductor switch that continues to deliver power to the controller and to the light unit when the switch unit is deactivated subsequent to being activated, to enable the light unit to remain illuminated after the switch unit has been deactivated.Type: GrantFiled: May 18, 2012Date of Patent: December 29, 2015Assignee: BLACK & DECKER INC.Inventors: Brian C.
