Latest Patents

One of Karl Scheller's latest patents involves methods and apparatus for magnetic article detection. This invention utilizes a first, True Power On State (TPOS) detector during an initial time interval, transitioning to a second, running mode detector once the output of the second detector is deemed accurate. A phase comparator is employed to respond to the output signals of both detectors, providing a control signal that indicates any changes in the phase relationship between the two outputs. The output switch, controlled by the phase comparator, delivers the first detector output signal during the initial time interval and the second detector output signal thereafter. Additionally, a threshold signal associated with the TPOS detector is maintained at a fixed level during the first portion of the time interval and is adjusted in response to an automatic gain control circuit to minimize phase errors during the transition. The patent also describes methods for updating a running mode threshold signal, which is a percentage of the peak-to-peak magnetic field sensor signal, thereby reducing unnecessary update events.
