Abstract: In a disk drive having a flexible circuit tail that is routed within a recess in the actuator arm, a dielectric spacer is added to the top of the tail in order to space the circuit traces within the tail further away from the electrically conductive actuator arm, and to make more repeatable that spacing. The added spacing reduces electrical coupling and thus increases the bandwidth of the circuit. The spacer can be in the form of a section of the same viscoelastic material that is used elsewhere as a vibration dampener on the suspension, the viscoelastic material being adhered to the tail before the tail is inserted within the recess. Alternatively, the spacer can be a thickened region of the flexible circuit covercoat in the area where the tail will reside within the recess.

Abstract: Systems and methods for controlling devices, including controller and actuators are disclosed. Actuators may be devices where remote control of the device or devices is convenient, such as lights, window shades, fans and similar items. In one method, a user sends a command to a controller and to an actuator. The controller also sends a proxy update to a second controller that is also in communication with the actuator. The proxy controller, also in contact with the actuator, now has knowledge of the state or position of the actuator and is in a better position if the proxy controller is asked to assume control of the actuator. In another method, an actuator or controller may also receive a trigger setup, asking the actuator to tell the controller when an action occurs, but not to take action until receiving a further command from the controller.

Abstract: Techniques are disclosed relating to securing physical compartments and allowing users access via a mobile device configured to use a mobile authentication system. In some embodiments, a locking device for a physical container is configured to unlock only if both a transaction authentication system confirms successful authentication of a mobile device and an auxiliary key is present. The locking device may receive encrypted data from the mobile device via a short-range wireless connection, transmit the data to the transaction authentication system, and receive a message indicating whether authentication was successful. The mobile device may encrypt the data using a replenishment key from the transaction authentication system; therefore the authentication may decrypt the received encrypted data to confirm an identity of the mobile device. In some embodiments, disclosed techniques may allow users to use their mobile device to unlock a safety deposit box without requiring extensive infrastructure investment, e.
