Latest Patents
One of Richardson's latest patents is a method and apparatus for reducing ambient noise effects in electronic devices. This invention provides a solution for adapting to noise sources that affect pulse oximeters. The method involves evaluating various available frequencies to determine their respective noise levels. One frequency is selected to act as the operating demultiplexer frequency. During normal operation, the pulse oximeter periodically scans the available frequencies to identify the one with the lowest associated noise. The noise level of the operating frequency is then used to assess the signal-to-noise ratio of the pulse oximeter signals. This process helps in qualifying certain signals and rejecting those with a signal-to-noise ratio below a predetermined threshold, ensuring accurate calculations of blood oxygen saturation.
