    Abstract: A crash sensor device may include multiple sensor components positioned along one or more data paths to a communication interface of the crash sensor device. The crash sensor device may include a test control unit. The test control unit may receive a test command from an electronic control unit during operation of a vehicle. The test control unit may perform a test of one or more sensor components, of the multiple sensor components, during operation of the vehicle based on the test command. The test control unit may output a test result to the electronic control unit based on performing the test.

    Abstract: A torque measurement system includes an outer rotational shaft and an inner rotational shaft both configured to rotate about a rotational axis. A rotation of the inner rotational shaft causes a rotation of the outer rotational shaft via a coupling structure. At least one torque applied to the inner rotational shaft is translated into a first torque-dependent angular shift between the shafts. A first metamaterial track is coupled to the outer rotational shaft and configured to co-rotate with the outer rotational shaft. A second metamaterial track is coupled to the inner rotational shaft and configured to co-rotate with the inner rotational shaft. The tracks are configured to convert an electro-magnetic transmit signal into a first electro-magnetic receive signal based on the first torque-dependent angular shift and a receiver is configured to receive the electro-magnetic receive signal and measure the at least one torque based on the electro-magnetic receive signal.

    Abstract: The described techniques address the issues of latency and lengthy processing times associated with conventional redundant sensor measurement systems that rely upon digital transmission protocols by implementing a diverse analog sensor interface architecture. The described architecture may advantageously use a number of sensor measurement paths that may be independent of one another or share any suitable number of common components to provide varying levels of redundancy. The analog interfaces may provide signal diversity with respect to the use of different types of analog transmission protocols, which may include different signaling interfaces (e.g. differential versus single-ended), different transmission interfaces (e.g. voltage versus current interfaces), and/or the use of different signalization schemes.

    Abstract: A sigma delta (SD) pulse-width modulation (PWM) loop includes a loop filter implementing a linear transfer function to generate a loop filter signal, wherein the loop filter is configured to receive an input signal and a first feedback signal and generate the loop filter signal based on the input signal, the first feedback signal, and the linear transfer function; and a hysteresis comparator coupled to an output of the loop filter, the hysteresis comparator configured to receive the loop filter signal and generate a sigma delta PWM signal based on the loop filter signal, wherein the first feedback signal is derived from the sigma delta PWM signal.

    Abstract: The described techniques facilitate the secure transmission of sensor measurement data to an ECU by implementing an authentication procedure. The authentication procedure includes an integrated circuit (IC) generating authentication tags by encrypting portions of sensor measurement data. These authentication tags are then transmitted together with the sensor measurement data as authenticated sensor measurement data. The ECU may then use the authentication tags to authenticate the sensor measurement data based upon a comparison of the portions of the sensor measurement data sensor measurement data to the authentication tag that is expected to be generated for those portions of sensor measurement data.

    Abstract: A torque measurement system includes a first rotatable carrier structure mechanically coupled to a rotational shaft; a second rotatable carrier structure mechanically coupled to the rotational shaft; a first mutually coupled structure including a first track mechanically coupled to the first rotatable carrier structure and a second track mechanically coupled to the second rotatable carrier structure, where the first track and the second track are coupled together by a first torque dependent coupling; a second mutually coupled structure including a third track mechanically coupled to the first rotatable carrier structure and a fourth track mechanically coupled to the second rotatable carrier structure, where the third track and the fourth track are coupled together by a second torque dependent coupling. In response to a rotation of the rotational shaft, the first torque dependent coupling is configured to increase and the second torque dependent coupling is configured to decrease.
