Latest Patents

James R. Trummer holds a patent for an ECG Amplifier overload control. This invention features an AC coupled amplifier system that is protected from overloading input signals through a 'bootstrap' circuit. This circuit provides a compensation signal that closely matches the overscale portion of the input signal. The compensation signal is applied to the coupling capacitor as an offset, preventing excessive charge accumulation. Additionally, a voltage-controlled current source acts as a signal range limiter, responding to overscale input signals by opening a circuit loop and forcing closure in a secondary feedback circuit. This process determines the extent of input signal overscale, allowing for the derivation of the matching compensation signal. The protection circuit also includes a reset function to manage extended overscale input signal levels.
