An area light is provided including a housing defining a central axis having a first end, a second end opposite the first end, and a side portion; a cover mounted on the first end of the housing; a light module disposed on the first end of the housing, the light module comprising a heat sink and at least one light-emitting diode (LED) to emit light through the cover and in a direction that extends 360 degrees around the center axis; and a battery receptacle disposed on the side portion of the housing to receive a removable battery pack and supply electric power form the removable battery pack to the at least one LED. At least one hook is provided on or adjacent the first end of the housing.

Area light

A power tool includes an electrostatic clutch assembly disposed between a motor and an end effector. A control circuit causes a first voltage to be applied to a first electrode of the electrostatic clutch assembly and a second voltage to be applied to a second electrode of the electrostatic clutch assembly, the first voltage being different from the second voltage, generating a first attractive force between the first and second electrodes, causing a shaft and a clutch housing to be coupled to each other when a torque on one of the shaft or the clutch housing is less than or equal to a first threshold value, and allowing the one of the shaft or the clutch housing to rotationally slip relative to the other of the shaft or the clutch housing when the torque on the one of the shaft or the clutch housing exceeds the first threshold value.

Electrostatic clutch for power tool

An electronic device with a microphone, a speaker, a processor, and a power tool battery pack connectable to and powering the speaker and the processor. The electronic device has software that can cause the processor to perform operations which can cause the electronic device to operate in first and second modes. While the electronic device is operating in the first mode, the device can generate first audio data representing user speech captured by the microphone which can be analyzed by the electronic device or a remote server. The electronic device can switch from operating in the first mode to operating in a second mode, where the electronic device can receive, second audio data from another electronic device. The electronic device can then output, using the speaker, audible content represented by the second audio data.

System and method for controlling jobsite products

A power supply apparatus is provided including a housing, at least one battery receptacle for receiving at least one removable battery pack, an inverter that converts a direct-current (DC) signal from the at least one battery pack to an alternating-current (AC) signal, and a controller that applies a pulse-width modulation (PWM) signal to the inverter to shape the AC signal with a lower harmonic distortion relative to a square wave. For each full cycle of the AC signal, the controller sets the duty cycle to approximately 100% within a first period corresponding to a peak area of the AC signal, to less than approximately 100% but greater than approximately 0% within a second period in which the AC signal transitions from the peak to a zero-cross following the first period, and to 0% within a third period corresponding to the zero-cross of the AC signal following the second period.

Portable power supply

A laser device operating system includes a laser device generating a laser beam when receiving a remote control unit command signal. The remote control unit operates in a public or private mode. In public mode the remote control unit generates a command signal transmitted to the laser device. In private mode the remote control unit generates a unique identifier prepended to the command signal. The laser device operates in a laser device public or private mode. In public mode the laser device responds to the remote control unit command signal or the command signal if transmitted by a second remote control unit. In private mode the laser device operates only upon receipt of the command signal and unique identifier, preventing laser device operation by the second remote control unit if the second unit does not include the unique identifier with the command signal.

Communication protocol for remotely controlled laser devices

A battery pack and charger platform including a voltage coupling circuit comprising an input that receives an input voltage and an output that sends an output voltage, a voltage monitoring circuit having an input coupled to the voltage coupling circuit output and an output, and a power source having an input coupled to the voltage monitoring circuit output, the power source input receives an input voltage representative of a charge instruction.

Battery pack and charger platform for power tool systems including battery pack identification scheme

It is common for a power tool system from a manufacturer to include a battery pack that is designed and configured to mate and operate with at least one power tool and a battery charger. However, as systems have evolved it has become desirable to provide a battery pack that is designed and configured to mate and operate with at least one power tool and a first battery charger but not a second battery charger. The present disclosure provides a battery pack including a housing, a terminal block, a plurality of terminals, and a mechanical lockout for allowing engagement with a power tool and a first battery charger while preventing engagement with a second battery charger.

Battery pack for cordless devices

The present disclosure is directed to a portable power supply system for providing power to corded power tools. The portable power supply is configured to charge a plurality of battery packs in parallel from an external power supply. The portable power supply is also configured to discharge the plurality of battery packs in series to an output connectable to a corded power tool.

A system including a carrier having a plurality of receptacles configured to receive rechargeable, removable battery packs, an AC power input connector for connecting to an AC power supply, a power output connector, a discharge/charge mode switch for switching between (1) a charging mode of operation that charges the battery packs using electrical power input through at least one of the power input connectors and (2) a discharging mode of operation that outputs electrical power from the battery packs through the power output connector, the charge/discharge control module controlling a plurality of charging switches to provide a charging current to the battery packs and an inverter electrically connected to the power output connector for providing an AC output signal at the power output connector.

Battery carrier system

The present invention is directed to a battery charger for charging a battery pack. The battery charger includes a plurality of components including a power supply. The battery charger also includes a temperature sensor that senses the temperature of at least one of the plurality of battery charger components, for example a transformer. The battery charger power supply is adjusted based on the temperature of the at least one of the plurality of battery charger components.
