  • Image capture with addition of accumulation signals for adjacent photodetectors
    Patent number: 9554065
    Abstract: An image capture instrument implements an addition of accumulation signals for photodetectors which are adjacent within a row of photodetectors. Segments are defined in the row with one and the same common length of segment, while being progressively offset by an offset length which is constant. The accumulation signals are added together for photodetectors which belong to one and the same segment. The offset length is less than the segment length, and greater than half said segment length. Artifacts in the image captured, which are due to spectrum aliasing, are thus decreased. The signal-to-noise ratio of the image is increased.

  • Friction liner having a network of grooves, for a clutch
    Patent number: 6290046
    Abstract: A torque converter includes a bridging clutch having an annular friction liner for engaging axially against a reaction surface of the clutch. The liner is in the form of an annular ring having a friction surface, an outer perimeter and an inner perimeter, with a network of grooves formed in the friction surface to enable a liquid to flow between the liner and the reaction surface. The network of grooves is not open radially in the outer perimeter of the liner.
