Patents by Inventor Patrice Favreau

Patrice Favreau 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: 9513709
    Abstract: A system that generates a haptic effect generates a drive cycle signal that includes a drive period and a monitoring period. The drive period includes a plurality of drive pulses that are based on the haptic effect. The system applies the drive pulses to a resonant actuator during the drive period and receives a signal from the resonant actuator that corresponds to the position of a mass in the actuator during the monitoring period.
    Type: Grant

  • Patent number: 7639232
    Abstract: Systems and methods for controlling a resonant device are described. One described method for braking an actuator includes generating a first actuator signal configured to drive the actuator, the first actuator signal having a first frequency approximately resonant to the actuator, and transmitting the first actuator signal to the actuator. The method also includes generating a second actuator signal, having a second frequency approximately 180 degrees out of phase to the first frequency, the second actuator signal configured to cause a braking force on the actuator, and transmitting the second actuator signal to the actuator.

  • Patent number: 6765224
    Abstract: A machine vision method and system for inspecting a material. The system comprises a light source arranged to illuminate the material and an imaging device configured to acquire image data corresponding to at least one characteristic of the material while the material is being illuminated by the light source. An image processor is configured to normalize the image data and to control adjustment of an exposure control level for the imaging device based upon the normalized image data. An exemplary method of implementing the machine vision system may include illuminating a material using a light source and obtaining image data corresponding to the material using an imaging device. The image data may be normalized and the adjustment of an exposure control level of the imaging device may be controlled based on the normalized image data.
