Latest Patents

One of his latest patents is titled "Optical record carrier having position identifying track modulation." This invention describes a system for recording and/or reading an information signal on an elongated track of an optically readable record carrier. The position-identifying signal, which is synchronous with a clock signal, is recorded on the track by modulating the transverse excursion of the track. This signal indicates the instantaneous position along the track at which the information signal is located. Notably, the frequency band of the position-identifying signal is situated substantially outside the frequency band of the information signal.

Another significant patent is for an "Equalizer with adjustable band filters and a digital filter suitable for." This invention involves a manually operated or automatic equalizer with adjustable band filters for varying the frequency characteristic of an electric signal. The equalizer has multiple band filters with their bands located adjacent to one another in a given frequency range. The central frequencies of filters having neighboring bands are designed to have a greater frequency separation than those of one-third octave filters.
