  • ANALYTE SENSING DEVICE
    Publication number: 20190003977
    Abstract: An analyte sensing device and a mobile device incorporating an analyte sensing device are disclosed. One example of an analyte sensing device is disclosed to include a body, a sensor die, and a substantially transparent material positioned such that the sensor die is sandwiched between the body and the substantially transparent material. The sensor die may be in optical communication with the substantially transparent material and in electrical communication with the body.

  • Polarizer structure to control crosstalk in proximity sensor including a cover physically separates a photodetector from an object
    Patent number: 9917582
    Abstract: An optical sensor, optical system, and proximity sensor are disclosed. An illustrative proximity sensor is disclosed to include a light source, a photodetector including a photo-sensitive area that receives incident light and converts the received incident light into an electrical signal, and a plurality of polarization layers stacked on the photodetector that limit light from becoming received incident light for the photo-sensitive area to light traveling toward the photodetector along a predetermined path.

  • Electronic device with ambient light sensor
    Publication number: 20060073844
    Abstract: An electronic device having a first piece, a second piece moveable between an open position and a closed position with respect to the first piece, and an ambient light sensor operable to detect ambient light when the second piece is not closed. The electronic device is operated in a first mode when the second piece is in an open position and in a second mode when the second piece is in the closed position.

  • Portable electronic device with activation sensor
    Publication number: 20060060762
    Abstract: An electronic device having a first piece, a second piece moveable with respect to the first piece, and a position sensor operable to sense the position of the second piece relative to the first piece. The electronic device is operated in a first mode or a second mode dependent upon the position of the second piece relative to the first piece. Optionally, a proximity sensor is provided to detect the presence of a body in close proximity to the device when the second piece is in an open position relative to the first piece.
