Abstract: Disclosed is an apparatus which has, among other things, a MEMS device with a first measurement arrangement for capturing a measurement variable (X1) based on a physical variable, which has a useful variable component (N1) and a first disturbance variable component (Z1), and a second measurement arrangement for capturing a second disturbance variable component (Z2). The apparatus furthermore has a disturbance compensation circuit which is configured to combine the second disturbance variable component (Z2) and the measurement variable (X1) with one another and to obtain a disturbance-compensated measurement variable (Xcomp). The MEMS device is arranged in a housing, wherein the MEMS device is in immediate mechanical contact with the housing by way of at least 50% of a MEMS device surface.

Abstract: An apparatus for determining a state parameter of an object to be monitored comprises a means for providing a plurality of measurement values, wherein the measurement values comprise information relating to the state parameter of the object to be monitored, a comparison means for comparing the measurement value to a predeterminable comparison parameter, wherein the comparison means is formed to output a first comparison signal when a predeterminable number of measurement values falls below the comparison parameter within a measurement interval, or to output a second comparison signal when the predeterminable number of measurement values exceeds or reaches the comparison parameter, wherein the first comparison signal or the second comparison signal indicate the state parameter.

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.

Abstract: A system includes an acceleration sensor for detecting a centrifugal acceleration, and a processing unit, which is coupled to the acceleration sensor and which is configured to determine numerical values from measured values of the centrifugal acceleration. The determined numerical values are representative of a mileage of a tire and/or wear of the tire and/or an installation radius of the system in the tire.

Abstract: Examples provide a method, a component, a tire-mounted TPMS module, a TPMS system and a machine readable storage or computer program for determining time information of at least one contact patch event of a rolling tire and a method for locating a tire. A method for determining time information of at least one contact patch event of a rolling tire, includes obtaining information indicative of a rotational rate of the tire; obtaining a sequence of samples indicative of at least an acceleration component during at least one rotation of the tire; and determining a position of at least one reference sample in the sequence, wherein the position of the at least one reference sample is indicative of the time information of the contact patch event of the rolling tire.

Abstract: Embodiments address a concept for exchanging information between time-of-flight ranging devices. For example, a first time-of-flight camera has an illumination unit configured to transmit information to a second time-of-flight camera by modulating a light signal to be emitted in accordance with an information bearing signal. The second time-of-flight camera has a time-of-flight sensor configured to detect the information bearing signal included in the emitted light signal of the first time of flight camera.
