Title: The Innovations of Frederick Y Kawabata
Introduction
Frederick Y Kawabata is a notable inventor based in Beaverton, OR (US). He holds a total of 4 patents that showcase his contributions to the field of electronics and signal processing. His work primarily focuses on developing advanced oscilloscope technologies that enhance the capabilities of electronic testing and measurement.
Latest Patents
One of his latest patents is for a general-purpose oscilloscope that features digital television signal display capability. This innovative oscilloscope employs circuitry designed to receive and convert serial digital video signals into composite and component analog signals through a digital to analog converter. The converted analog signals are then applied to the oscilloscope's signal inputs for monitoring and display. This oscilloscope is preferably a digital phosphor oscilloscope, equipped with control menus that manage both the traditional functions of the oscilloscope and the serial digital video circuitry. Additionally, it includes apparatus for storing data and waveforms, along with circuitry that derives a trigger signal from a specific digital word within the serial digital bit stream. This allows the oscilloscope to capture and display television waveform information around unique occurrences of events specified by the digital word.
Another significant patent involves an apparatus for deriving a trigger signal from the AC line. This method utilizes two wires that are non-conductively attached and capacitively coupled to a two-wire AC power line. Each capacitive pick-off connects to a differential amplifier for amplification. The output signal replicates the AC power line signal, allowing for a detection threshold set near zero volts, making it insensitive to amplitude variations. This design includes a low pass filter to eliminate undesired higher frequencies and an additional amplifier for greater amplification of the filtered AC line signal.
