Latest Patents

One of Zatsman's latest patents is titled "System and method for determination of contact lens orientation." This invention provides a system and method to determine the orientation or pose of a contact lens residing on the transparent bottom of a fluid-filled, typically opaque-sided cuvette. The system can determine whether the contact lens is in a concave up or concave down orientation, and whether the lens is everted. An illuminator is aligned on a longitudinal axis of the cuvette through the contact lens, while a vision system camera is positioned beneath the bottom of the cuvette. The camera acquires images of the contact lens, and the vision system identifies the appropriate edges and features of the lens. These features allow for the categorization of the lens poses as either acceptable or unacceptable.

Another significant patent by Zatsman is the "Synchronization signal detection and phase estimation apparatus." This invention involves a digital television (DTV) receiver that processes a data signal divided into segments, each separated by a known data segment sync sequence. The receiver includes a data segment sync signal detector that filters the data signal to provide a filtered output. The detector computes differences between samples of the filtered signal and an expected value, allowing for accurate detection of the data segment sync sequence and initial phase estimation.
