Latest Patents

One of his latest patents is titled "Registration mark detection using matched filtering." This system and method enhance the resolution between matching and non-matching inputs associated with an object. The registration mark represents a binary code sequence, and upon detecting a sequence of bits with a sensor, the detected sequence is provided to a code matching filter. This filter compares the detected sequence with the binary code sequence and produces a detection signal. The code matching filter increases the value of the detection signal for each matching pair of compared bits while decreasing it for non-matching pairs, effectively assessing penalties for mismatches. This results in a high amplitude output for matching inputs and a low amplitude for non-matching inputs. The system is designed to sample the detected sequence of bits to avoid potential edge timing problems.

Another notable patent is "Binary registration mark detection using 3-state sensing and matched filtering." This invention involves a system and method for detecting a registration mark that represents a binary code sequence of N bits. A sensor outputs values indicating whether positive bits, negative bits, or no bits of the binary code sequence are detected. A sequence of N sensor values is provided to a code matching filter for comparison with the binary code sequence. The filter increases the detection signal value for each matching sensor value, decreases it for complementary sensor values, and remains neutral for sensor values indicating no bit detection. When the binary code sequence is a Barker code, the filter yields the ideal Barker auto-correlation function response whenever the sequence is detected.
