Publication number: 20250141247Abstract: Data are optically transmitted from a power tool device, such as a power tool, a power tool battery charger, power tool pack adapter, and/or a battery pack. The data are stored in a memory of the power tool device and are encoded as optical signal data to provide an encoded representation of the stored data. An optical transmitter (e.g., a light emitting diode or a flat panel display) transmits the optical signal data, which are detected or otherwise received by an optical receiver device, which may include a camera or other photodetector. The optical signal data may include light signals generated by an LED, where the data are encoded using an encoding scheme that modulates one or more characteristics (e.g., amplitude, wavelength, color) of the generated light signals. The optical signal data may also include images (e.g., barcodes, QR codes) or characters.Type: ApplicationFiled: September 27, 2022Publication date: May 1, 2025Inventors: Jonathan E.

Patent number: 12251801Abstract: A method of controlling a rotary impact tool includes activating a motor to provide torque to a drive assembly, providing rotational impacts to a torque stick coupled to an anvil of the drive assembly in response to a reaction torque on the drive assembly exceeding a threshold value, and sensing a position of the anvil with a position sensor. The position sensor transmits a first signal indicative of the anvil rotating in a first direction and a second signal indicative of the anvil rotating in a second direction, where the second direction is a rebound angle of the anvil. The method further includes calculating a torque transferred from the torque stick to a workpiece by multiplying the rebound angle by a torsional stiffness value of the torque stick and deactivating the motor in response to the torque exerted on the workpiece being substantially equal to a torque limit.Type: GrantFiled: April 11, 2024Date of Patent: March 18, 2025Assignee: MILWAUKEE ELECTRIC TOOL CORPORATIONInventors: Jonathan E.
