  • Patent number: 11569995
    Abstract: Apparatus and method for managing devices within a trust boundary of a computer network. In some embodiments, a trust manager circuit uses a first registration authority to authenticate a plurality of processing devices to form a trust group. A new processing device is subsequently added to the group. The trust manager circuit uses a different, second registration authority to provisionally authenticate the new processing device in response to an unavailability of the first registration authority, and grants provisional rights to the new processing device. Once the first registration authority is once again available, the trust manager performs a full authentication of the new processing device and grants full rights to the device.

  • Patent number: 11541471
    Abstract: A method for interconnecting multiple components of a head-gimbal assembly with a solder joint, including the steps of positioning a first component adjacent to and at an angle relative to a second component to provide a connection area between the first and second components, dispensing a solder sphere to a capillary tube having tapered walls, wherein the capillary tube is positioned with an exit orifice above the connection area between the first and second components, pressurizing the capillary tube until a predetermined pressure is reached, applying a first laser pulse to the solder sphere to liquefy the solder sphere until it falls from the exit orifice, waiting for a predetermined time period after the liquefied solder sphere has exited the exit orifice of the capillary tube, and applying a second laser pulse to reflow the solder sphere to create the solder joint between the first and second components.
