Title: The Innovative Contributions of Bernard J. Yorkanis

Introduction

Bernard J. Yorkanis is a notable inventor based in South Plainfield, NJ (US). He has made significant contributions to the field of electronics, particularly in the development of technologies used in television apparatuses. With a total of 5 patents to his name, Yorkanis has demonstrated a commitment to innovation and advancement in his field.

Latest Patents

One of his latest patents is a level shifter for a power supply regulator in a television apparatus. This invention involves a level shifter that receives a variable input voltage, such as a beam current representative voltage of a cathode ray tube. It produces an output voltage that changes in relation to the input voltage, ensuring that the output voltage is level shifted accordingly. This output voltage is then coupled to an input terminal of an error amplifier within a power supply voltage regulator of a television receiver. The level shifter utilizes a current mirror arrangement that responds to the input voltage, while a band gap type voltage source determines the extent of the level shifting produced.

Another significant patent by Yorkanis is a delay circuit employing an active bandpass filter. In this invention, a signal to be delayed is applied to a frequency-selective path that includes an inverting active bandpass filter, as well as a non-frequency selective path that includes a voltage-to-current converter. These paths are connected to a signal combiner, which generates an output current that consists of components proportional to both the converter's output current and the filter output voltage. This design allows for the cascading of several circuits for purposes such as peaking and delay equalization in television receivers and video disc players.
