Patents by Inventor Joseph D. Barbera

Joseph D. Barbera 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: 7596328
    Abstract: An efficient sensing system. The efficient sensing system includes a first mechanism for sensing and a second mechanism for sensing. A third mechanism selectively polls the second mechanism upon receipt of a signal from the first mechanism. In a specific embodiment, the first mechanism includes an early warning sensor, and the second mechanism includes an accurate sensor. In the specific embodiment, the third mechanism includes a controller in communication with the accurate sensor and the early warning sensor. The controller samples the accurate sensor at the sampling rate in response to the signal.
    Type: Grant
    Filed: April 22, 2003
    Date of Patent: September 29, 2009
    Assignee: Hewlett-Packard Development Company, L.P.

  • Patent number: 6464417
    Abstract: A multi-purpose, transmissive paper sensor includes a light beam projector and light detector having an analog output signal. Changes in the output signal from an open loop condition indicate the presences of at least one print medium being in the field-of-view of the sensor. Output signals indicative of print media leading edge, trailing edge, and number of sheets interrupting the light beam provide improved print media transport control for hard copy apparatus.
