Latest Patents

One of his latest patents is a bus request buffer circuit for interfacing between field maintenance. This invention involves a buffer circuit that connects a bus request conductor to a processor and a bus request terminal of a first circuit. The circuit is designed to assert control over a data bus coupled to the processor. It includes a flip-flop that indicates whether the first circuit is monitoring or driving its bus request terminal. The buffer circuit also reproduces the logic level of the bus request conductor based on the state of the flip-flop.

Another significant patent is related to wait circuitry for interfacing between a field maintenance processor and a microprocessor. This invention allows for transparent refreshing of dynamic memory by timing the duration of the 'wait' signal produced by slower memory or peripheral devices. The counter circuit generates a 'wait enable' signal that ensures the processor receives the 'enabled wait' signal for a predetermined time. If the wait signal persists beyond this time, an interrupt routine is executed to refresh the dynamic memory.
