Latest Patents
Ravid's latest patents include a high-efficiency voltage converter and regulator circuit. This invention involves a voltage converter and a method for converting AC to DC. A MOSFET conveys current from a full-wave rectifier to charge a capacitor that supplies current to a load. In one embodiment, two transistors are connected as a differential pair to control the voltage applied to the gate of the MOSFET, referenced to a zener voltage developed across a zener diode connected to the emitters of the two transistors. In another embodiment, a single transistor controls the voltage applied to the gate of the MOSFET relative to a zener voltage of a zener diode. The MOSFET charges the capacitor while the voltage applied to its gate from the rectified signal is greater than the voltage across the capacitor.
Another significant patent is for a display having redundant segments. This invention utilizes redundant segment display characters to provide a fail-safe indication of critical parameters. Selected segments of a redundant segment character include pairs of segments arranged proximate to each other and extending generally parallel. These pairs of redundant segments are activated simultaneously in response to multiplexed foreplane and backplane drive signals applied to conductive regions of a liquid crystal display. The design minimizes errors in reading a numeric value indicated by the character in the event that one of the segments fails to operate properly.
