Latest Patents
Among Stanley E. Lehnert’s latest inventions are two groundbreaking patents. The first, the "Saturable Reactor with Toroidal Shunt Paths," presents a novel saturable reactor design that employs a center control winding electromagnetically coupled to a pair of outer windings. This innovation offers side pincushion correction and eliminates center pinch in raster-scanned video displays, such as cathode ray tubes (CRTs). The design boasts high inductance-to-resistance ratios, allowing for increased deflection current to horizontal deflection coils without necessitating an increase in size.
The second patent, the "Pulse Wave to Parabola Wave Converter," describes an electronic image framing circuit aimed at rectifying pincushion distortion at television image edges. By employing a pulse processor that responds to conventional horizontal and vertical rate pulses, this circuit develops blanking pulses with widths varied at a vertical rate, effectively blanking video line portions that extend beyond the desired image area. Additionally, a parabola generator is described, which is crucial for producing the modified blanking pulses.
