Abstract: Systems and methods are provided to ingest data objects from a flat file server for use in one or more system operations including providing a renderable data object to a user and updating a data item database. As described, the ingestion system includes an ingestion module, a flat file module, a compliance module, and a deduplication module wherein the modules together ingest a flat file data object, parse and process a renderable data object from the flat file data object, and store the renderable data object in a renderable object database.

Abstract: An apparatus for increasing the rate of expansion of tissue area and volume, either in vivo or in vitro, which comprises a tissue expansion device suitable for expansion of tissue and a controller connected to the device, wherein the controller causes the device to subject the tissue to stretching forces that alternatively increase and decrease to provide a series of stretch and relax phases during a period of tissue expansion without intervention of an operator.

Abstract: An arrangement for processing video signals, the video signals having the form of digitally encoded samples and being arranged to produce a television picture by line and field sequential scanning includes a frame store, a write address generator and a read address generator. Input video samples are fed from an input to an interpolator for writing into the store.When a television picture is to be rotated and the rotation is effected by the sequence of write addresses to the store a situation can arise where there is no information available for writing into certain store locations. This results in holes appearing in the output signal where no picture related information is present. A hole detector is provided at the store output and controls an interpolator which inserts information derived from adjacent picture samples into the hole.

Abstract: A serial switched interconnection network comprises several stages of switching units each having a plurality of source ports and destination ports interconnected so that any source port of the first stage can be connected to any destination port of the final stage by operation of switching units in successive stages. Connections are by shared data and control paths each of which paths may comprise a single line or multiple lines and each switching unit when switched to along a path sends a request back up that path for sufficient data signals to operate the switching unit initiating the request. The setting up of a path through the network is thus stage-by-stage asynchronously.

Abstract: A video signal processing arrangement for television signals encoded in digital form comprising means for compressing and/or expanding the size of the television picture represented by the video signal and means for rotating the television picture represented by the video signal is disclosed. The rotating means is separate from the compressing and/or expanding means and is switchable between a position prior to the compressing and/or expanding means in the video signal processing chain and a position subsequent to the compressing and/or expanding means. An arrangement having two separate video signal paths which are later combined to produce a composite picture is also described in which the rotating means can also be positioned after the combining means as well as before or after the compressing and/or expanding means in either path.

Abstract: An arrangement for rotating television pictures comprises a frame store into which a rotated input picture is written under the control of a write address generator which is in turn controlled by a rotation control and timing generator. A video input signal is applied at input and fed to a splitting circuit which produces streams of even and odd numbered samples, both at the sampling rate. These streams of samples are fed to an interpolator where they are used to generate samples to be written into the store. The store is split into four areas which are arranged to hold respectively field 1 odd samples, field 1 even samples, field 2 odd samples, and field 2 even samples.
