Latest Patents

One of Groeschel's latest patents is titled "Modulation circuitry for use in a music encoding system." This invention discloses an apparatus for encoding data representative of keyboard music. In the preferred embodiment, the data source is a keyboard played by a musician, incorporating a set of switches that form key closures. These closures represent the music, which is encoded by grouping the keyboard into convenient-sized groups, typically octaves. All of these groups are input to a buffer, where a multiplexer scans the buffer. Timed generators form synchronization waveforms, space waveforms, and mark waveforms, which are generated in a timed sequence. These waveforms are input to a flip-flop that forms an output word on a two-wire carrier system, encoding all necessary data for word decoding, including clock, sync, mark, and space data.

Another notable patent is the "Battery charging apparatus." This invention is designed for a nickel-cadmium battery and utilizes a type of solid-state resistor formed of a plurality of paralleled emitter follower transistors. These transistors collectively serve as a load for the Ni-Cd battery. The apparatus senses the charging requirements and adjusts a control voltage, which is compared with a reference voltage. This control voltage is applied to a circuit that conditions a signal to adjust the conductivity of the emitter follower transistors as needed. The device allows for charging or discharging through the solid-state resistor over a timed interval.
