  • Patent number: 11921174
    Abstract: The present application relates to a technical field of determining an irreversible demagnetization of a grain boundary diffusion NdFeB magnet, and more particularly, to a method for identifying an irreversible demagnetization of a grain boundary diffusion NdFeB magnet by magnetic field distribution. After applying a reverse magnetic field to a saturatedly magnetized grain boundary diffusion NdFeB magnet, if a number of magnetic poles on a non-diffusion face of the grain boundary diffusion NdFeB magnet is increased, it is determined that there is an irreversible demagnetization in the grain boundary diffusion NdFeB magnet.

  • Publication number: 20180173288
    Abstract: According to certain aspects, a system includes frequency measurement devices distributed across a power domain on a chip, wherein the power domain is divided into multiple power sub-domains, and each of the power sub-domains includes a respective subset of the frequency measurement devices. The system also includes a power manager. For each of the power sub-domains, the power manager is configured to receive frequency measurements from the respective subset of the frequency measurement devices, and determine a supply voltage setting for the power sub-domain based on the received frequency measurements from the respective subset of the frequency measurement devices.

  • Patent number: 9620452
    Abstract: An apparatus including a conductive stack structure includes an Mx layer interconnect on an Mx layer and extending in a first direction on a first track, an My layer interconnect on an My layer in which the My layer is a lower layer than the Mx layer, a first via stack coupled between the Mx layer interconnect and the My layer interconnect, a second via stack coupled between the Mx layer interconnect and the My layer interconnect, a second Mx layer interconnect extending in the first direction on a track immediately adjacent to the first track, and a third Mx layer interconnect extending in the first direction on a track immediately adjacent to the first track. The Mx layer interconnect is between the second Mx layer interconnect and the third Mx layer interconnect. The second Mx layer interconnect and the third Mx layer interconnect are uncoupled to each other.
