  • Publication number: 20220057210
    Abstract: Columnar multi-axis microelectromechanical systems (MEMS) devices (such as gyroscopes) balanced against undesired linear and angular vibration are described herein. In some embodiments, the columnar MEMS device may comprise at least two multiple-mass columns, each having at least three proof masses and being configured to sense rotation about a respective axis. The motion and mass of the proof masses may be controlled to achieve linear and rotational balancing of the MEMS device. The columnar MEMS device may further comprise one or more modular drive structures disposed alongside each multiple-mass column to facilitate displacement of the proof masses of a respective column. The MEMS devices described herein may be used to sense roll, yaw, and pitch angular rates.

  • Publication number: 20220046337
    Abstract: A passive wireless sensor may be wirelessly coupled with an interrogator. The sensor uses multiple antennas to receive an interrogation signal from the interrogator and compares a path length difference between the signal received at each antenna. The path length difference changes based on the relative position of the sensor and interrogator. Using the path length difference, the sensor transmits a response signal to the interrogator. The interrogator analyzes the response signal to determine sensor position. The interrogator compares the determined sensor position to a previous known sensor position to determine if an attack has occurred, such as a replay, counterfeit, or tampering attack. The sensor may include cryptographic circuitry that scrambles the response signal, thwarting an attack such as a sniffing attack. The interrogator may include multiple antennas and determine a position of the sensor by calculating an angle-of-arrival that enhances a signal from the sensor, via beamforming.

  • Publication number: 20210239539
    Abstract: Packages for wireless temperature sensor nodes are described. These wireless temperature sensor nodes are suitable for sensing the temperature of remote objects, such as objects that are difficult to access. These packages are designed to enhance the sensor's ability to sense temperature. For example, these packages may be designed to provide a low thermal resistance path between the object and the temperature sensor, a high thermal resistance between an antenna of the wireless temperature sensor node and the object, and at least in some embodiments, immunity to vibrations. One such package includes means for providing a thermal conductive path from the temperature sensor to a thermally conductive support in contact with the object (for example with a thermal resistance less than 10 K/W), and means for thermally conductively decoupling the circuit board from the thermally conductive support (for example by at least 100 K/W).
