Abstract: A heterogeneous sensor system includes a magnetic field sensor and an inductive sensor. A checker is configured to receive the magnetic field sensor output signal and the inductive sensor output signal and determine whether an error has occurred based on a comparison of the magnetic field sensor output signal and the inductive sensor output signal. Targets include at least a portion that is conductive and may include a ferromagnetic portion for back biased magnetic sensing. Additional features include on axis and off axis positioning of the sensors with respect to the target, multi-track targets for absolute position sensing, angle sensing and torque sensing configurations.

Abstract: Methods and apparatus receiving data at a first time from at least one sensor, determining a parameter from the received data for the first time, estimating the parameter for a future time based on the data for first time, and outputting the estimated parameter for the future time to a receiving device. In some embodiments, an IC package can process the received data to generate the estimated parameter for the future time. The IC package may transmit the estimated parameter using a particular protocol. In some embodiments, the receiving device can treat the estimated parameter as real-time data.

Abstract: A sensor integrated circuit (IC) includes a sensing element configured to sense a parameter associated with a target, a processor coupled to the sensing element and configured to generate a sensed signal indicative of the parameter associated with the target, and an output module coupled to receive the sensed signal. The output module is configured to transmit absolute data on a message line at a first rate and transmit incremental data on one or more index lines at a second rate, wherein the second rate is faster than the first rate, wherein the incremental data comprises data associated with changes in the absolute data and wherein an edge or a pulse is used to indicate an incremental change has occurred in the absolute data.

Abstract: Methods and apparatus for determining a mechanical angle of a target from sine and cosine signals generated by inductive sensing elements by applying harmonic compensation on the sine and cosine signals using possible mechanical angles and analyzing results of the applied harmonic compensation. One of the mechanical angles can be selected based on the results of the applied harmonic compensation. In embodiments, a cost function can be used to select the mechanical angle.
