  • Patent number: 11707950
    Abstract: Sensor and method for determining operating states associated with one or more tires. The operating state of the tire can be determined based on one or more measures environmental conditions of the tire(s). For example, a controller can be configured to determine a change in one or more environmental conditions, including determining, for example, a rate-of-change value, a variance value, a standard deviation, or the like. The rate-of-change, variance, and/or standard deviation values can be compared to one or more threshold values to determine the operating state(s) associated with the tire(s). The environmental condition can include, for example, acceleration of the tire, pressure of the tire, and/or temperature of the tire. The operating state can be, for example, a filling state indicative of the tire being inflating, and/or a drive state indicative of the tire rotating about its axle.

  • Patent number: 9915707
    Abstract: Embodiments relate to xMR sensors having very high shape anisotropy. Embodiments also relate to novel structuring processes of xMR stacks to achieve very high shape anisotropies without chemically affecting the performance relevant magnetic field sensitive layer system while also providing comparatively uniform structure widths over a wafer, down to about 100 nm in embodiments. Embodiments can also provide xMR stacks having side walls of the performance relevant free layer system that are smooth and/or of a defined lateral geometry which is important for achieving a homogeneous magnetic behavior over the wafer.

  • Patent number: 8700286
    Abstract: Embodiments relate to tire localization in tire pressure monitoring systems (TPMS). In embodiments, a TPMS includes a wheel unit and a control unit. Each wheel unit collects acceleration data and transmits that data to the control unit for processing. The control unit processes the data and, using additional data received from another vehicle system, for example an antilock braking system (ABS) or electronic stability control (ESC) system, correlates the data in order to localize each wheel unit to a particular wheel of the vehicle. Advantages include increased processing power at the control unit as compared to the wheel unit.
