Title: The Innovations of Carl L. Ostrowski
Introduction
Carl L. Ostrowski is a notable inventor based in Ann Arbor, MI (US). He has made significant contributions to the field of electronics, particularly in the development of circuits for integrated circuit (IC) testing. With a total of 5 patents to his name, Ostrowski's work has had a lasting impact on the industry.
Latest Patents
One of his latest patents is a single-transistor two resistor circuit that translates test signals to selectable voltage levels. This signal translator circuit is designed for use in sending test signals to an IC-chip in a chip testing system. It includes first and second resistors, and a single transistor that has a current channel coupled in series with the first resistor between a source voltage terminal and an output terminal. The transistor also has a control lead for enabling and disabling the flow of current through the current channel, which receives an input test signal at voltage levels that are to be translated. The output terminal is coupled through the second resistor to a reference voltage terminal and is also connected to an input terminal of a socket structured to hold the IC-chip.
Another significant patent is an electromechanical module for holding IC-chips in a chip testing system. This module includes a circuit board with a plurality of sockets mounted thereon, each designed to hold one IC-chip for testing. Each socket has a corresponding register on the circuit board, and a bus sends a timing pulse to a clock input on all of the registers in parallel. This module also concurrently sends a clock signal and N-1 test signals to N data inputs on all of the registers.
