Abstract: A system that stores sets of data blocks in extents located in storage devices is described. During operation, a receiving device receives, through an RPC framework, a first call asking to transfer an extent from a sending device to the receiving device. In response, the receiving device opens a port for a data connection that operates outside the RPC framework. The receiving device makes a second call, to the sending device through the RPC framework, asking to stream the extent to the port. The receiving device subsequently receives the extent from the sending device through the port and computes a checksum for the extent. The receiving device also receives a return from the second call, including a checksum for the extent computed by the sending device. If the computed checksum matches the received checksum, the receiving device returns the first call to indicate the transfer operation completed successfully.

Abstract: An append-only data storage system is described that stores sets of data blocks in extents that are located in storage devices. During operation of the system, upon receiving a request to copy an extent from a source storage device to a destination storage device, the system creates a scratch extent on the destination storage device, and associates the scratch extent with a private identifier, whereby the scratch extent can only be accessed through the private identifier. The system uses the private identifier to perform a copying operation that copies the extent from the source storage device to the scratch extent on the destination storage device. After the copying operation is complete and the scratch extent is closed, the system associates the scratch extent with a public identifier, whereby the copy of the extent on the destination storage device becomes publically accessible to other entities in the data storage system.

Abstract: The disclosed embodiments relate to the design of an append-only data storage system that stores sets of data blocks in extents that are located in storage devices in the system. During operation of the system, when an extent is in an open state, the system allows data blocks to be appended to the extent, and disallows operations to be performed on the extent that are incompatible with data being concurrently appended to the extent. When the extent becomes full, the system changes the extent from the open state to a closed state. Then, while the extent is in the closed state, the system disallows data blocks to be appended to the extent, and allows operations to be performed on the extent that are incompatible with data being concurrently appended to the extent.

Abstract: The disclosed embodiments relate to the design of an append-only data storage system that stores sets of data blocks in extents that are located in storage devices in the system. During operation of the system, when an extent becomes full, the system changing the extent from an open state, wherein data can be appended to the extent, to a closed state, wherein data cannot be appended to the extent. Changing the extent from the open state to the closed state includes performing the following operations at one or more storage devices that contain copies of the extent: constructing an index to facilitate accessing data blocks in a copy of the extent contained in the storage device; and appending the index to the copy of the extent in non-volatile storage in the storage device.

Abstract: A append-only data storage system that stores sets of data blocks in extents that are located in storage devices. When an extent becomes full, the system changes the extent from an open state, wherein data can be appended to the extent, to a closed state, wherein data cannot be appended to the extent. This change involves performing a synchronization operation by: obtaining a list of data blocks in the extent from each storage device that has a copy of the extent; forming a union of the lists; looking up data blocks from the union in a database that maps data blocks to storage devices and extents to determine which data blocks belong in the extent; and if a copy of the extent is missing data blocks that belong in the extent, performing a remedial action before changing the extent from the open state to the closed state.

Abstract: A feeding apparatus includes a container, a flexible mouthpiece, and a partition. The container includes an open end and defines a main chamber. The flexible mouthpiece defines a secondary chamber in the container and includes a teat. The partition separates the main and secondary chambers and is part of a resiliently biased cartridge. When the flexible mouthpiece and partition are brought together, a flow restrictor is formed. A moveable part of the cartridge is configured to be biased towards a first position by a biasing element, and is moveable against the bias from the first position to a second position. The cartridge at least substantially closes a path for a flow of liquid feed through the flow restrictor and between the main and secondary chambers when the moveable part is in the first position, and opens the path when the moveable part is in the second position.

Abstract: A display system is provided to surround a user with an out-the window scene. The system includes a screen structure that is a facetted back-projection dome made up of a polygonal polar top facet surrounded by trapezoidal facets angulated downward from it in an upper facet row. A middle row of facets extends angulated downward therefrom, and a lower row of trapezoidal facets extends down from them. Each facet has video projected thereon by a high definition projector, and to maximize resolution and efficiently use the projector output, the vertical height of each facet makes use of the full vertical field of pixels available from the associated projector. The facets are all tangent to a sphere about a design eyepoint of the dome. The projector resolutions and the size, position and material of the facets are such that the imagery visible on the inside of the dome on the facets is at resolution corresponding to a visual acuity of 20/50 or higher, preferably 20/20, and at or near eye-limiting resolution.

Abstract: Colic can be a particular problem for babies feeding on liquid feed from a feeder bottle. The colic can be formed by air from various sources in the liquid feed. Typically, there is less air in the liquid feed towards the bottom of the liquid feed container in the feeding position than towards the top of the liquid feed. The present invention provides apparatus for drawing milk from the bottom of the feeding apparatus chamber when the feeder is held in the operating position. This is achieved by positioning a flow restrictor for allowing the passage of liquid feed from a main chamber into a flexible feeding teat at a suitable location. The present invention also provides a resiliently-biased cartridge to assist in priming and/or draining of the flexible feeding teat. The present invention also provides a construction in which the flow restrictor is always provided in the correct position regardless of the relative angular orientation of the elements of the feeder.
