Abstract: A digital cell for performing a logic operation on a logic input to produce a logic output, includes an evaluation block and a sense-amplifier block, both configured to receive input signals representative of the logic input, and to detect when the logic input and/or input signals validly encode at least one bit. The digital cell is configured to alternate between an evaluate state and a reset state. Upon the digital cell being in the reset state and the detection, the digital cell is switched from the reset state to the evaluate state in which the evaluation block generates a difference in its output signals, and the sense-amplifier block amplifies the difference so that the output signals encode at least one valid bit. Upon the digital cell being in the evaluate state, the digital cell can be triggered to reset to the reset state.

Abstract: An intensity image is collected at each of a plurality of locations spaced apart in a propagation direction of a light beam. Information from the intensity images is combined using a Kalman filter which assumes that at least one co-variance matrix has a diagonal form. This leads to considerable reduction in computational complexity. An augmented Kalman filter model (augmented space state model) is used in place of the standard Kalman filter model. The augmented Kalman filter improves the robustness to noise.
