    Abstract: A fault detection system includes a state register, an error detection code (EDC) register, logic circuitry, an EDC generator, and an EDC checker. The state and EDC registers store first reference data and first checksum data, respectively. The logic circuitry executes a logic function based on the first reference data to iteratively generate second reference data that is different from the first reference data, and updates the first reference data of the state register with the second reference data of one iteration. The EDC generator iteratively generates second checksum data based on the iteratively generated second reference data and updates the first checksum data of the EDC register with the second checksum data of one iteration. The EDC checker detects a fault in the IC based on the updated first reference data and the updated first checksum data.

  • Publication number: 20240393398
    Abstract: Various techniques for determining self-discharge rates of one or more battery cells, such as by determining a current leakage of the battery cell(s), are described. The techniques may improve the effective ADC linearity. An example of a technique may calculate the average time when each ADC digital code is observed, such as for a given battery cell or battery module, which allows the battery cell discharge rate to be estimated from the interval between the average time observed for neighboring, e.g., adjacent, digital codes. This approach allows the self-discharge rate of a battery cell to be calculated with high resolution even when the total cell voltage excursion is only a few least significant bits (LSBs).

  • Publication number: 20240393425
    Abstract: Methods, systems, and devices for wireless communications are described. Aspects of the disclosure provide techniques for wireless devices utilizing wireless communications systems to perform radar operations to leverage challenges within radar signaling to detect one or more adverse parties attempting to spoof one or more radar signals. For example, a base station may transmit, to one or more vehicles, a message including an indication of a challenge type, when the challenge is to be applied, or both. Based on the challenge, one or more vehicles may detect that a device associated with the adverse party is not following the challenge as dictated in the message. Based on the detection, the one or more vehicles may report, to the base station, the detection of an adverse party attempting to spoof radars within the wireless communications system.

  • Publication number: 20240393427
    Abstract: A radar system uses multiple nulls to improve detection capabilities. Multiple radar pulses are transmitted and or received, each with a different null pattern. The returns from each pulse are averaged together to form a null window that is less noisy and potentially wider than a single null pattern. This approach can improve the signal-to-noise ratio and make it easier to detect objects of interest. The system may generate individual pulses from an AESA divided into several subarrays. Each subarray produces a pulse with a null in a different location in the radiation pattern centered about a location of interest. The contemporaneous return signals are averaged together.

  • Publication number: 20240393429
    Abstract: A device may include a receive (Rx) antenna input to couple an Rx antenna to an Rx chain, and a signal coupler to inject the test signal toward the Rx antenna. The device may include an Rx antenna switch to, in a first switch state, cause the Rx antenna to be isolated from the Rx chain and, in a second switch state, permit the test signal to probe the Rx antenna. The Rx chain may measure a phasor of a first baseband signal generated based on a first reflected test signal and a phasor of a second baseband signal generated based on a second reflected test signal. The device may include a control circuit to compute a complex ratio based on the phasors, compute a measured reflection coefficient based on the complex ratio and using a transfer function, and monitor an impedance matching of the Rx antenna.

    Abstract: A method for authenticating an object includes positioning a millimeter-wave transceiver relative to an object which contains a metamaterial marking. A transmit signal is transmitted from the millimeter-wave transceiver in the direction of the metamaterial marking, wherein the transmit signal is converted based on the metamaterial marking into a receive signal which has a first characteristic and is emitted in the direction of the millimeter-wave transceiver. The receive signal is received and processed by the millimeter-wave transceiver in order to capture the first characteristic. First comparison information is generated based on the first characteristic and an authentication of the object is carried out based on the first comparison information.
