    Abstract: A data storage device is disclosed comprising a microactuator configured to actuate a head over a disk. A control signal applied to the microactuator is generated based on an input sequence u(k). A Preisach bit map bj is updated based on the input sequence u(k), wherein the Preisach bit map bj corresponds to a Preisach plane modeling a hysteretic response of the microactuator. A current compensation value yi is generated based on an update value generated based on: ? j ? h ? ( j ) ? b ^ j where hj represents a slice of the Preisach plane and {circumflex over (b)}j is an update bit map based on at least part of the Preisach bit map bj.

  • Patent number: 8958169
    Abstract: A data storage device is disclosed comprising a disk comprising a plurality of tracks defined by servo sectors, a head, and a servo controller configured to servo the head over the disk based on an estimated state generated by a state estimator. The servo controller is configured to execute a seek operation to seek the head over the disk and recover from a servo fault during the seek operation by generating an initial state estimate of the head at the beginning of the servo fault, and decelerating the head open-loop using a model-based deceleration control in response to the initial state estimate. While decelerating the head, the state estimator is re-qualified before the head reaches zero velocity, and after re-qualifying the state estimator and before the head reaches zero velocity, a seek operation is executed to seek the head to a target track closed-loop using the state estimator.

  • Publication number: 20140294389
    Abstract: The invention provides a method and apparatus for controlling an optical network unit to restart upon completion of downloading new software. Upon completion of downloading a new software version, an optical network terminal firstly determines a type of an active image request to be transmitted based upon stored values, of a RstDelayTimeRange attribute and of a RstDelayTrafficThreshold attribute, corresponding to the optical network unit, and then transmits the active image request to the optical network unit. The determined active image request may be a first active image request to instruct the optical network unit to immediately restart and activate the new software version that has been downloaded, or may be a second active image request to instruct the optical network unit to set an activation flag and a third active image request to instruct the optical network unit to immediately restart, both of which are used in combination.

  • Patent number: 8276380
    Abstract: A zero-emissions power plant receives natural gas from wells at elevated pressure and temperature. Gas is expanded through one or more turbo-expanders, preferably reformed, and sent to a fuel cell where electricity, heat, carbon-dioxide, and water are generated. The carbon-dioxide is compressed by at least one compressor and piped downhole for sequestration. The turbo-expanders have shafts which preferably share the shafts of the compressors. Thus, energy given up by the natural gas in the turbo-expanders is used to run compressors which compress carbon dioxide for downhole sequestration. In one embodiment, the natural gas is applied to heat exchangers in order to generate a stream of liquid natural gas. The remainder of the gas is expanded through the turbo-expanders and processed in the reformer prior to being sent to the fuel cell. A shifter may be used between the reformer and fuel cell. A solid oxide fuel cell is preferred.
