Latest Patents

Alexandra holds a patent titled "Detection of close-range specular targets." This imaging apparatus includes a camera equipped with an autofocus mechanism. The range sensor features a transmitter with multiple emitters that transmit optical pulses at various angles toward the scene. A receiver senses the respective times of flight of the reflected optical pulses. The photodetector outputs a signal indicative of the intensity of reflections from the scene. The control circuitry alternates the emitters to transmit the optical pulses, estimates the range to a target based on the sensed times of flight, and detects differences in the photodetector's output signal. The autofocus mechanism is adjusted responsively to the estimated range, provided the detected difference does not exceed a predefined threshold difference. Alexandra has 1 patent to her name.
