  • Publication number: 20090082161
    Abstract: A differential assembly includes a differential carrier (5) with a first carrier part (6) with a free first annular face (13) and a second carrier part (7) connectable to the first carrier part (6) and having a free second annular face (15), and a plurality of circumferentially distributed recesses (9) formed between the two carrier parts (6, 7); per carrier part (6, 7), a sideshaft gear (22, 23) is rotatably supported therein; and a supporting element (10) with journals (12) is held in the differential carrier (5). Each of the journals engages one of the recesses (9) of the differential carrier (5) and carries a differential gear (19) for driving the sideshaft gears (22, 23). The first and the second carrier part (7) are welded along a joining region formed between the two annular faces (13, 15) which is interrupted by the recesses (9) in the circumferential direction.

  • Publication number: 20050104089
    Abstract: A MOS or CMOS sensor for high performance imaging in broad spectral ranges including portions of the infrared spectral band. These broad spectral ranges may also include portions or all of the visible spectrum, therefore the sensor has both daylight and night vision capabilities. The sensor includes a continuous multi-layer photodiode structure on a many pixel MOS or CMOS readout array where the photodiode structure is chosen to include responses in the near infrared spectral ranges. A preferred embodiment incorporates a microcrystalline copper indium diselenide/cadmium sulfide photodiode structure on a CMOS readout array. An alternate preferred embodiment incorporates a microcrystalline silicon germanium photodiode structure on a CMOS readout array. Each of these embodiments provides night vision with image performance that greatly surpasses the GEN III night vision technology in terms of enhanced sensitivity, pixel size and pixel count.
