Jeffrey E Stahmann, Jesse W Hartley, Quan Ni, Kent Lee, John D Hatlestad: Sleep logbook. Cardiac Pacemakers, Hollingsworth & Funk, August 11, 2009: US07572225 (110 worldwide citation)

An approach to collecting and organizing information associated with events affecting sleep is presented. The sleep logbook system may acquire information associated with the sleep during periods of sleep and/or during periods of wakefulness. The information is organized as a sleep logbook entry. Th ...

John D Hatlestad, Gerald F Sauter: Optical differentiation between plants and background utilizing a single CCD camera. Lockheed Martin Corporation, Glenn W Bowen, April 15, 1997: US05621460 (76 worldwide citation)

An optical system for detecting vegetation with the use of a single image sensor, such as a charge coupled device (CCD) camera is provided by optical elements which project separate red and near infrared (NIR) images onto the CCD camera. The camera then can supply output signals representative of th ...

John D Hatlestad: Red/near-infrared filtering for CCD cameras. Lockheed Martin Corporation, Glenn W Bowen, September 10, 1996: US05555464 (43 worldwide citation)

A CCD camera is adapted for detecting red and near-infrared wavelengths by employing filters that are constructed to allow for the passage of only red light in certain areas and near-infrared light in other areas of the filter. The areas are designed to match the pixel geometry of the lens of a prim ...
