  • Patent number: 12239996
    Abstract: 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.

  • Patent number: 12122411
    Abstract: 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).

  • Patent number: 12073144
    Abstract: 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.

  • Publication number: 20240119034
    Abstract: A data migration and integration system is disclosed. In various embodiments, the system includes a memory configured to store a mapping from a source schema to a target schema; and a processor coupled to the memory and configured to migrate to a target schema an instance of source data organized according to the source schema, including by using a chase engine to perform an ordered sequence of steps comprising adding a bounded layer of new elements to a current canonical chase state associated with migrating the source data to the target schema; adding coincidences associated with one or more of the target schema data integrity constraints and a mapping from the source schema to the target schema; and merging equal elements based on the coincidences; and repeat the preceding ordered sequence of steps iteratively until an end condition is met.

  • Publication number: 20230308277
    Abstract: This disclosure relates to a method for anonymous attestation that includes receiving, by an application running on a client device and from a first content provider, an authentication request to authenticate a user to receive content from a second domain of a second content provider, redeeming, with an attestation token issuing system that issued an anonymous attestation token attesting to the user's authentication to the second content provider, the anonymous attestation token by transmitting the anonymous attestation token with a second request, receiving a redemption result representing whether the attestation token was successfully redeemed, signed by the attestation token issuing system using a digital signature and is operable to verify, to the second content provider, that the user is authenticated to the second content provider without identifying the user to the second content provider, and transmitting, to the first content provider, the redemption result.
