Latest Patents

One of Lambert's latest patents is an "Apparatus and method for monitoring hand washing." This invention provides a method and apparatus to monitor and document that proper hygienic procedures are followed by food service providers. It consists of a camera, a processor controlling the camera, and software to accomplish the hand washing monitoring. The criteria for identifying the start and end of a hand washing event by monitoring activity in selected areas is presented. A record is created of the wash event, including a sequence of photographs during the event and additional related data such as start time, duration, location, and any employee identification. This record is available for recording or downloading to a server for further manipulation, including washer identification and statistical analysis.

Another notable patent is the "Method for measuring ultrasonic transit times." This invention provides an algorithm for enhancing the transit time measurement of an ultrasonic wave through a fluid. It includes criteria for evaluating the suitability for various waveforms with regard to noise rejection. The transit time calculation offers greater noise immunity and accuracy than techniques used in the prior art. It allows for a measure of weighting of dispersed signals with different arrival times. The calculation utilizes either the transmitted signal or the measurement of a reference system, and it calculates the squared convolution of this signal with the received signal. The symmetry of the calculated autocorrelation function predicts the accuracy of the algorithm.
