Patent number: 12239996Abstract: A material reduction machine includes a prime mover driving a cutting mechanism. A drive system receives a signal to initiate rotation of a cutting mechanism. A sensor senses a machine load parameter and reports a signal to a controller operatively coupled to the clutch to control sequential engagement cycles from the engine to the cutting mechanism. The controller utilizes a stored first disengagement threshold value for stopping a first engagement cycle and continues monitoring the signal as the machine load parameter increases momentarily after reaching the first disengagement threshold. The controller determines and adopts a second disengagement threshold value based on observation of the machine load parameter indicative of maximum load during the continued monitoring after the first disengagement threshold is realized, and further being based on a stored correction factor. The second disengagement threshold value is used for a second engagement cycle.Type: GrantFiled: November 9, 2022Date of Patent: March 4, 2025Assignee: Vermeer Manufacturing CompanyInventors: Joseph Edward Breja, David Isaac Barker

Patent number: 12122411Abstract: A system generates haptic feedback in an electric vehicle. The system comprises a frame, an energy storage device, and a wheel rotatably coupled to the frame. A motor receives power from the energy storage device and provides torque to the wheel. A controller determines a first operational state of the electric vehicle and transmits a first torque signal to the motor to control the motor to transmit first torque levels to the wheel to propel the electric vehicle. The controller determines a second operational state of the electric vehicle and transmits a second torque signal to the motor assembly. The motor assembly transmits second torque levels to the wheel to generate haptic feedback. The second torque signal is based on the second operational state of the electric vehicle and a torque profile stored in the memory, where the torque profile defines an irregular-shaped periodic waveform (e.g., a heartbeat rhythm).Type: GrantFiled: April 4, 2023Date of Patent: October 22, 2024Assignee: LiveWire EV, LLCInventors: David Isaac Aunkst, Eric James Klumpp, Tim Monahan, Sean M.

Patent number: 12073144Abstract: A method for interfacing tones with a computer enables a music device to emulate the functions of a computer keyboard. The method includes receiving a digital signal representing one or more note events and identifying a group of concurrent notes from the one or more note events, wherein the one or more note events each have a pitch, a velocity and an initiation. In accordance with a pitch class of a base note of the group of notes and intervals computed between pitch classes of the notes of the group as ordered by the pitch of the note events, the group of notes are translated into a computer input signal representative of one or more keystrokes on a computer keyboard and the computer input signal is sent to a computer for output or further processing.Type: GrantFiled: March 5, 2021Date of Patent: August 27, 2024Inventor: David Isaac Lazaroff
