Latest Patents

Forbes' latest patents demonstrate his expertise and focus on critical areas of technology:

1. **Robust time-diversity filter and method for removing electromagnetic interference**: This invention discloses an apparatus and method for filtering signals during an epoch that includes both a quiet and an event epoch. It encompasses a mechanism for generating electrical digitized signals and includes a memory to store these signals. An event detector identifies the event and quiet epochs, while a spectrum analyzer assesses the power spectrum of the digitized signals. An estimator calculates electromagnetic interference (EMI) from the quiet epoch and subtracts this from the event epoch signals, resulting in improved signal clarity.

2. **Calculating a heart rate from an ECG waveform by discarding a percentage**: In this invention, Forbes devised a method and apparatus for accurately calculating a patient's heart rate from multiple ECG waveforms gathered via several electrodes. The heart rate calculation logic developed by Forbes evaluates the intervals between heartbeats, discards the extremes in interval lengths, and averages the remaining intervals. This innovation allows for a robust heart rate calculation even amidst the noise often present in clinical environments.
