Latest Patents

Hemme's latest patents include a resonant degaussing apparatus and a sine wave deflection circuit for bidirectional scanning of a cathode ray tube. The resonant degaussing apparatus features a system where first and second capacitors are charged prior to a degaussing interval. A first switch couples the first capacitor to a degaussing coil to initiate the degaussing interval. This design allows the first capacitor and the degaussing coil to form a resonant circuit that generates a decaying degaussing current. During a specific portion of each cycle of the degaussing current, a second switch couples a precharged second capacitor in parallel with the first capacitor. This charge transfer arrangement replenishes energy losses in the first capacitor, thereby increasing the duration of the degaussing interval.

The sine wave deflection circuit utilizes a capacitively coupled square wave generator to provide a steady state sinusoidal current flow in a deflection winding of a cathode ray tube. The tank circuit formed by the deflection winding, capacitive coupling, and an additional capacitor filters out the odd harmonics of the square wave generator. This results in a sinusoidal current in the deflection winding, enabling bidirectional scanning.
