Latest Patents
Eric M Lafontaine holds a patent for a "System and method for determining angular position and controlling rotor orientation." This invention involves methods and devices for determining the position and/or angular orientation of a rotating shaft. Key features of this patent include a sensor module and a position determination module. The sensor module may consist of multiple Hall Effect devices (HEDs) arranged at specific angular separations to generate signals in response to the rotation of the shaft. The position module is designed to respond to the sensor module, producing a converted signal, determining an error term, and generating a position estimate. The converted signal is created by processing the HED signals into sinusoidal reference signals with offset scale and amplitude scale factors. The error term is derived from processing the converted signals to yield an estimated position signal. The position estimate is then produced by processing the error term, allowing for refined position measurement through iterative elimination of regressive differences between position estimates while minimizing the absolute magnitude of the error term.
