  • Vehicle detection loop and loop deterioration assessment
    Patent number: 10520629
    Abstract: Systems and methods for vehicle detection and assessments of loop deterioration rely on changes in inductance of a loop sensor. The conductive element of the loop sensor is modeled using one or more inductances and one or more resistances. Sets of stimuli at different frequencies are provided to the loop sensor, and the resulting responses form the basis for vehicle detection and for an assessment whether the loop sensor has deteriorated.
    Type: Grant
    Filed: July 11, 2018
    Date of Patent: December 31, 2019
    Assignee: HM Electronics, Inc.
    Inventors: David O'Gwynn, Shane Robert Petcavich
