Title: Innovations of Daniel C. Upp: A Trailblazer in Optical and Signal Processing Technologies
Introduction: Daniel C. Upp, based in Southbury, CT, is an accomplished inventor with an impressive portfolio of 35 patents. His contributions to the field of optical and signal processing have made significant impacts on modern telecommunications.
Latest Patents: Among his latest innovations is the patent for an integrated circuit designed for programmable optical delay. This breakthrough addresses interference caused by the transmission of a signal between antennas, utilizing an improved signal cancellation system. The system includes an interference cancellation signal generator, which produces a time-delayed and amplitude-reduced representation of the transmit signal. This design allows for substantial interference reduction by employing a summing stage that subtracts the modified transmit signal from the received signal. Additionally, his innovation incorporates a novel programmable optical delay line and a thyristor-based sigma delta modulator for converting samples of the transmit signal into a digital format in the optical domain.
Upp also holds a patent for methods related to SONET/SDH SPE virtual container retiming, which enhances the efficiency of SONET signal processing. This method involves demultiplexing STS-1 signals, buffering them in a FIFO structure, and calculating leak rates based on FIFO depth and pointer movements. This method ensures effective management of signal flow, optimizing the operation of telecommunications systems.
