  • Patent number: 11176979
    Abstract: A logic-memory cell includes a spin-orbit torque device having first, second and third terminals configured such that current between the second and third terminals is capable of changing a resistance between the first and second terminals. In the cell, a first transistor is connected between a logic connection line and the first terminal of the spin-orbit torque device and a second transistor is connected between the logic connection line and the third terminal of the spin-orbit torque device.

  • Patent number: 10890667
    Abstract: The present invention discloses a cubature Kalman filtering method suitable for high-dimensional GNSS/INS deep coupling, including: S1, constructing a high-dimensional GNSS/INS deep coupling filter model; S2, generating an initialization cubature point for the constructed filter model by using standard cubature rules; S3, performing CKF filtering by using novel cubature point update rules. The present invention is suitable for high-dimensional GNSS/INS deep coupling filtering with high precision and high stability.

  • Patent number: 10302711
    Abstract: An article may include a substantially perpendicularly magnetized free layer having a first magnetic orientation in the absence of an applied magnetic field. The article may also include a spin Hall channel layer configured to conduct a spin current configured to subject the perpendicularly magnetized free layer to a magnetic switching torque and a substantially in-plane magnetized bias layer configured to bias the substantially perpendicularly magnetized free layer to a second magnetic orientation. The second magnetic orientation is different than the first magnetic orientation and is out of a plane of the substantially perpendicularly magnetized free layer.

  • Patent number: 10217522
    Abstract: In some examples, an electronic device comprising an input ferroelectric (FE) capacitor, an output FE capacitor, and a channel positioned beneath the input FE capacitor and positioned beneath the output FE capacitor. In some examples, the channel is configured to carry a magnetic signal from the input FE capacitor to the output FE capacitor to cause a voltage change at the output FE capacitor. In some examples, the electronic device further comprises a transistor-based drive circuit electrically connected to an output node of the output FE capacitor. In some examples, the transistor-based drive circuit is configured to deliver, based on the voltage change at the output FE capacitor, an output signal to an input node of a second device.
