Latest Patents

Daugherty's latest innovations include two vital patents:

1. **Systems and methods for delineating a cell in a communications network** - This patent describes a method for performing cell delineation in a communications network. The process involves providing a data cell that is defined based on a communications protocol, which forms a part of a data stream. The method also maps this data cell into frames defined by a network protocol, with adjacent frames separated by a frame boundary. Within the data cell lies a boundary data unit, which not only defines the cell boundary but also includes validation information for an associated segment of data units. The analysis of these data units facilitates identifying the boundary data unit and the frame boundary, thereby ensuring integrity and efficiency in data communications.

2. **Self-sweeping autolock PLL** - This patent presents an improved phase-lock loop (PLL) circuit, including a phase detector, loop filter, and voltage-controlled oscillator. The innovation samples the phase-lock loop input signal at various cycle points of the output signal, which allows the detection of logic state transitions. Importantly, the self-sweeping autolock circuit commands the loop filter to adjust its output signal when phase-lock is not achieved while halting the adjustments once phase-lock is acquired. This development enhances the performance and stability of phase-locked loops in electronic applications.
