摘要:
An orientation-independent hydraulic system comprises a dynamic fluid reservoir defining a first volume substantially equal to the volume of the fluid therein, and a hydraulic cylinder in fluid communication with the dynamic fluid reservoir. The hydraulic cylinder has a second volume of hydraulic fluid and a piston rod configured to extend and retract in response to changes in the second volume. A first hydraulic pump is configured to pump hydraulic fluid between the hydraulic cylinder and the dynamic fluid reservoir, thereby moving the piston rod between the extended and retracted positions.

The technology herein relates to rotating a second structure, which can be a turret, relative to a first structure, which can be a vehicle. The system can include a motor unit having a motor with a motor gear to rotate a drive shaft and a drive gear. A manual input shaft can also be configured to transmit rotation to the drive shaft. The motor can have a central axis that forms an angle of less than 90 degrees with a plane substantially defined by an outer surface of a gear box coupled to the motor. A mounting bracket is configured to allow mechanical communication between the motor unit and an internal ring gear. The mounting bracket has a mounting frame defining at least a first slide channel. A first motor unit coupler has a slide flange that is slidably received by the mounting frame and receives a motor unit. The internal ring gear can be mounted to a vehicle and a turret can be pivotably disposed within the internal ring gear. A motor unit is mounted on the turret and a drive gear is rotatably mounted on the motor unit and in direct engagement with the internal ring gear.

摘要:
A network adaptor that generates interrupts to a host system when data is received from the network or downloaded from system memory for transmittal over the network. The adaptor generates interrupts after a delay determined by an interrupt deferral mechanism, which includes one or more timers and/or one or more counters. Interrupts are generated, for example, after a predetermined time has elapsed after a DMA completion or after a certain number of packets are counted.

An adapter is provided with intelligence that allows it to separate the header parts of a packet being received from the payload it carries, and in most cases move the payload directly into a destination buffer at the application layer or file system layer. Copies by the intermediate layers of the protocol stack are bypassed, reducing the number of times that the payload of a communication must be copied by the host system. At the network interface, a plurality of packets is received, and the payload of each is bypassed directly into the target destination buffer. The network interface device identifies the packets which are in the sequence of packets carrying payload to be stored in the target buffer by the flow specification carried with such packets. Also, the packets carrying data payload for the file include a sequence number or other identifier by which the network interface is able to determine the offset within the target buffer to which the packet is to be stored.

摘要:
A reactor coolant system of a pressurized water nuclear reactor with fuel assemblies in the core is simultaneously shutdown and decontaminated in less than 90 hours after the shutdown is initiated. A LOMI or Can-Derem decontamination reagent is added to reactor coolant to reduce iron and nickel in oxidized coatings before removing dissolved hydrogen and reducing the gamma emitting activity of the reactor coolant.

A network transmitter schedules packets so that packets are transmitted to a host or group of hosts so as not to overload any particular part of the network. In an embodiment, the transmitter uses packet data structures with a schedule indication for packets placed in the queue so that an independently running adaptor may know when to remove packets from the queue and transmit them. In an alternative embodiment, packets are scheduled by setting a future interrupt for transmitting a packet or group of packets. In a further embodiment, packets are placed in temporal sets where a temporal set is a group of packets that can be transmitted in succession without violating the bandwidth limitations of any network segment.
