Abstract: An articulated tug barge hopper dredge including a tug, a barge, and a coupling system configured to interconnect the tug and the barge. The tug has a bow and the barge has a notch in a periphery of the barge. The notch is sized to receive the bow of the tug. The articulated tug barge hopper dredge further includes dredging machinery integrated with the barge and configured to excavate material dredged from the seabed. The dredging machinery includes trailing suction pipes.

Abstract: A mooring buoy assembly includes a floating structure, a pipe, an elbow, and a swivel joint. The pipe extends vertically into and away from the floating structure, and is fixed to the floating structure such that the floating structure does not rotate with respect to the pipe. Furthermore, the pipe is configured to provide a flow path in fluid communication with a submerged hose. The elbow is in fluid communication with the pipe and provides a change in direction of the flow path. Furthermore, the elbow is supported by the floating structure and is configured to be in fluid communication with a floating hose. The swivel joint is connected to the pipe and is configured to allow the elbow and floating hose to rotate relative to the submerged hose.

Abstract: In accordance with the present invention, electronic mixing is provided between multiple instruction channels from multiple users of a single controlled object such that each user can have partial control over the object at the same time. The percentage of partial control is adjusted between users according to any combination of the number of users, preset or user set percentages, randomness, or computer generation.

Abstract: An apparatus adapted to obtain a profile of a density gradient sample independently of fractionation is provided. The apparatus includes a light source, a probe comprising a first probe needle actuatable to extend into a tube containing a sample, a first light-transmitting means to receive light from the light source and transmit light through the sample as the probe needle extends into the sample, a second light-transmitting means to receive light transmitted by the first light-transmitting means and transmit the received light to a signal-producing means capable of translating the received light into a recordable signal to produce a profile of the sample. The apparatus may additionally be adapted to fractionate the sample following generation of the gradient profile.

Abstract: An electronic tire maintenance system is provided for measuring a parameter of a device at a first location. The system includes a sensor for measuring the device parameter and generating a data signal representing the measured parameter. The system also includes a microprocessor coupled to the sensor for activating the sensor on a first periodic basis to measure the device parameter. The microprocessor includes a memory for storing the generated data signal representing the measured parameter. A transmitter and a receiver are coupled to the microprocessor. The microprocessor periodically partially awakens to determine, on a second periodic basis, if a received transmission is a valid interrogation signal and, if so, fully awakens and responds to the valid interrogation signal, via the transmitter, by at least transmitting the last stored measured parameter.

Abstract: A method and system of data backup for a computer system is disclosed. Full and incremental backups of data stored to a first storage device coupled to the computer system are stored to a backup storage device coupled to the computer system. The backup storage device may be remotely located and coupled via a network. Data representative of the relationship of each incremental backup to its respective parent backup is stored in a dependency data structure, preferably a tree-like structure. Different types of incremental backups may be performed to provide different data granularity. When two or more storage media are used in a rotational manner, each medium always contains a complete backup. The backup storage device is automatically managed by paring at least one of a full and incremental backup at the backup storage device automatically in accordance with a plan. The plan is preferably configured to manage an amount of available storage space at the backup storage device.
