Patents by Inventor Venkata Rama Varma Dantuluri

Venkata Rama Varma Dantuluri 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: 9701341
    Abstract: A space frame for a machine is disclosed. The space frame may have a first end configured to be connected to front wheels of the machine. The space frame may also have a second end configured to be connected to rear wheels of the machine. Further, the space frame may have primary structural members arranged substantially lengthwise between the first end and the second end. In addition, the space frame may have secondary structural members connected between the primary structural members to form substantially triangulated structures allowing the space frame to support a payload to empty vehicle weight ratio ranging from about 1.2:1 to 2:1.
    Type: Grant
    Filed: August 3, 2015
    Date of Patent: July 11, 2017
    Assignee: Caterpillar Inc.
    Inventors: Edward Patrick Ormiston, David William Holthaus, Andres Munoz-Najar, Venkata Rama Varma Dantuluri

  • Patent number: 8209094
    Abstract: A hydraulic implement system for a machine is disclosed. The hydraulic implement system may have a boom member, a boom actuator, and a boom operator control device movable to indicate a related operator desired boom member velocity. The hydraulic implement system may also have an implement pivotally connected to the boom member, an implement actuator, and an implement operator control device movable to indicated a related operator desired implement velocity. The range of the implement operator control device may be divided into a first portion and a second portion. The hydraulic implement system may also have a controller configured to selectively limit a velocity of the implement during manipulation of the implement operator control device within the first portion such that a lift velocity of the boom member of at least 65% of the desired boom member velocity is always possible.
