Title: The Innovative Contributions of Daniel T. Sullivan

Introduction: Daniel T. Sullivan, an accomplished inventor based in Bolton, MA, has made significant strides in the field of technology with a total of seven patents to his name. His work primarily focuses on audio systems and memory addressing, showcasing his expertise in engineering and innovation.

Latest Patents: Among his latest patents, one stands out: the Audio Delay System. This invention involves variably delaying an audio signal by storing digital representations of the signal at sequential memory locations. An encoding pointer operates at a specific clock rate, reading from the memory at prescribed locations determined by a decoding pointer, which can function at the same or a different rate, allowing for flexibility in delay management.

Another notable patent involves a memory addressing system where a processor specifies the high-order portion of a memory address, while a separate counter, operating at a much higher clock rate, provides the low-order portion. This innovation enhances data retrieval efficiency and speed.

Additionally, Sullivan has contributed to the generation of narrowly-separated variable-frequency clock signals. By employing a voltage-to-frequency converter that utilizes output from an integrator, he has developed a method to generate clock signals with slightly different frequencies while preventing them from synchronizing, an essential requirement in many modern electronic applications.

Career Highlights: Throughout his career, Sullivan has worked with renowned companies such as Digital Equipment Corporation and Analog and Digital Systems, Inc. His contributions in these roles have played a crucial part in advancing their technological capabilities.

Collaborations: Collaborating with notable figures such as Charles H. Kaman and James F. O'Loughlin has further enriched Sullivan’s professional journey. Through these partnerships, he has been able to enhance his innovative thinking and approach to complex engineering problems.

Conclusion: Daniel T. Sullivan exemplifies the spirit of innovation in the realm of technology. His inventions have not only advanced audio processing and memory addressing systems but have also laid the groundwork for future developments in these fields. As he continues to innovate, the impact of his work will resonate within the industry for years to come.
