John E. Yestrau 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: 11185966
    Abstract: A re-useable, easily removable tool pin features a non-stick outer surface with a harder inner core configured to be gripped by a removal tool for extraction of the tool pin, without damage, from a mold and from composite plies that may have cured in contact with the tool pin. The tool pin prevents insertion into the mold such that the extractor tool is not attachable to the tool pin. A system includes the tool pin, a mold for forming a molded part, the mold having holes for insertion of tool pins, and an extractor tool adapted to grip the tool pin for removal from the mold and molded part. The extractor tool can be ergonomically designed for easy removal of the tool pin by hand. Such tool pins are adapted for production of parts from composite materials in many industries, including aerospace, automotive, transportation, agricultural, and energy.

  • Patent number: 7899618
    Abstract: A method of guiding a vehicle comprises sensing a position of a laser beam using a laser sensor and receiving a signal from the laser sensor wherein the signal is representative of the position of the laser beam. The method further includes interpreting the signal, generating a control signal in response to the laser beam being greater than a predetermined distance from a predetermined reference position and wherein the control signal is configured to control the vehicle to track the position of the laser beam. The method additionally comprises sending the control signal to a drive actuator.

  • Patent number: 7536242
    Abstract: An optical laser guidance system includes a laser sensor, a controller and a plurality of actuators. The laser sensor detects a projected laser beam and sends an electrical signal representative of the position of the laser beam to the controller. The controller interprets the representative signal and uses the position of the laser beam relative to a predetermined reference position to generate a control signal to control an actuator in order to control the direction of travel of a vehicle or robot with respect to a predetermined guidepath. The laser sensor may also receive additional control messages that result in the controller generating additional control signals to control additional actuators in order to perform additional functions. The optical laser guidance system may also include a laser projection system capable of projecting a two- or three-dimensional guidepath and additional control messages.
