Abstract: Data transmission from a data storage device (DSD) to a host. Data is received from a volatile memory of the DSD in an ingress buffer of the DSD and the data from the ingress buffer is formatted into formatted data. A size of data buffered in the ingress buffer is compared to a frame ingress size for data to be buffered in the ingress buffer for a frame to be transmitted to the host. It is determined based on the comparison whether to buffer all of the formatted data for the frame in an egress buffer of the DSD before transmission to the host, or to transmit at least a portion of the formatted data for the frame to the host before all of the formatted data for the frame is received in the egress buffer.

Abstract: A data storage device is disclosed wherein a host interface state machine receives an access command from a host, the access command identifying a plurality of logical block addresses (LBAs). A host interface processor generates at least one control structure executed by the host interface state machine in connection with servicing the access command. The host interface processor directs a master processor to execute the access command, and the master processor updates a LBA register in connection with executing the access command. The host interface state machine executes the control structure to compare a target LBA to the LBA register and communicates with the host in response to the comparison.

Abstract: A communications network comprises a plurality of linked nodes between a source and a destination. At each node the state of the network and its links are measured and stored with advertisements from other links. The node also performs a routing algorithm to define the instantaneously best path to the destination for the current network state. The routing algorithm responds to a plurality of metrics, including costs of links, and may use fuzzy logic which derives a fuzzy cost for candidate paths to derive a least fuzzy cost path to be followed. Traffic is shared between a path which is determined to be the best, at the current point in time, and a path which has previously been determined as the best path. The network can be a network which carries mobile cellular traffic.

Abstract: A communications network, particularly for mobile cellular traffic, whose topology changes as a function of time and usage includes a plurality of linked nodes between a source and destination and at each node the state of the network and its links are measured and. stored with advertisements from other links. The node also runs, for each of a traffic type defined by QoS requirements and/or precedence, a routing algorithm to define the instantaneously best path to the destination for the current network state and updated either periodically or whenever the network metrics are changed by traffic load to a significant extent. The routing algorithm responds to a plurality of metrics, including costs of links, and may use fuzzy logic which is set up to derive a fuzzy cost for candidate paths to derive a least fuzzy cost path to be followed.

Abstract: Advanced boresight equipment and methods of using the same to effect a transfer of a two- or three-dimensional frame of reference from an ADL to a device to be boresighted.The equipment includes a stationary inertial sensor that is boresighted with respect to a reference line (such as the aircraft ADL). The stationary inertial sensor includes a first gyroscopic combination for generating a first output indicating a two- or three-dimensional frame of reference based on the ADL, and a docking station. The docking station facilitates alignment of a portable inertial sensor that also has a gyroscopic combination for generating a second output indicating its frame of reference.

Abstract: A gyroscopic system and method is provided for translating parallel and non-parallel lines between a reference line and a device to be aligned with respect to the reference line. A first inertial sensor is provided that is configured to be substantially stationary. This inertial sensor is boresighted with respect to the reference line and includes at least two gyroscopes and a mirror having first and second nonplanar surfaces. A second, portable inertial sensor is provided that includes a gimbal, a gimbal drive system, an electronic energy beam generator, a collimator, and at least two gyroscopes. One or more of the electronic beam generator, collimator, and gyroscopes can optionally be mounted on a platform that is mounted on the gimbal and adapted to move in accordance with signals from the gimbal drive system. A control circuit is provided that is operable to measure output signals generated by the first and second inertial sensor gyroscopes and to determine relative orientations of the inertial sensors.
