Patents by Inventor Anthony J. Weltzer

Anthony J. Weltzer has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11208097
    Abstract: Methods include electronically monitoring sensor or transceiver location information to detect a location of a machine. Responsive to detection of the machine, determining if the machine is located within a first geographic region, and if the machine is located within a first geographic region, electronically sending a command to an actuator that is coupled to the machine to initiate a first response. The first response includes limiting a height of an implement that is coupled to a chassis of the machine. The implement being height-adjustable relative to the chassis by action of the actuator.
    Type: Grant
    Filed: May 6, 2019
    Date of Patent: December 28, 2021
    Assignee: Caterpillar Inc.

  • Patent number: 11117583
    Abstract: A brake system for an articulated vehicle is disclosed. The brake system includes a brake assembly coupled to a traction device, the brake assembly being configured to apply a brake-assembly pressure based on one of a hydro-mechanical pressure signal and an electro-mechanical pressure signal. A blocking valve is configured to block the hydro-mechanical pressure signal when closed. A brake controller, is configured to transmit an isolation signal configured to close the blocking valve and transmit an ABS control signal that is based on a commanded ABS brake pressure.

  • Patent number: 11052906
    Abstract: A dynamic roll over control system generates ground speed signals indicative of a current speed and compares the current speed to a desired speed. The desired speed is determined based upon the machine characteristics, the payload of the bed, the yaw rate of the bed, the pitch rate of the bed, and the roll angle of the bed. When the current speed of the machine exceeds the desired speed, the controller generates prime mover control signals to control operation of the prime mover to slow the machine so the current speed does not exceed the desired speed.
