Title: The Innovations of Peter K. Cheung
Introduction
Peter K. Cheung is a notable inventor based in Milpitas, California. He has made significant contributions to the field of computer systems, particularly in the development of SCSI (Small Computer System Interface) technology. With a total of four patents to his name, Cheung's work has had a lasting impact on the way devices communicate within computer systems.
Latest Patents
One of Cheung's latest patents is a SCSI bus transceiver and method for making the same. This invention discloses a SCSI host adapter designed for use in computer systems. The adapter provides interconnection with both internal and external target devices. It features a low voltage differential connector for connecting to a low voltage differential bus, which communicates a first transaction. Additionally, it includes a single-ended connector for interconnecting to a single-ended bus, facilitating a second transaction. The transceiver unit interfaces between the two buses and produces a target information signal to indicate which transaction is occurring.
Another significant patent addresses methods and apparatus for monitoring the termination status of a SCSI bus. This invention provides a solution for users when the bus is either under-terminated or over-terminated, conditions that can prevent the bus from functioning properly. The system includes a precision resistor connected to the bus, which produces a voltage drop that is monitored to indicate the number of terminators present. This monitoring circuit notifies users of any improper termination conditions, enhancing the reliability of SCSI bus operations.
