Fixed length means having a set length that never varies. In database systems, a field can have a fixed or a variable length. A variable-length field is one whose length can be different in each record, depending on what data is stored in the field. The terms fixed length and variable length can also refer to the entire record.
Synchronous network for digital media streams
InactiveUS6611537B1Avoid collisionPulse modulation television signal transmissionTime-division multiplexData streamNetwork clock
A network adapter for a synchronous logical ring network operates on existing physical twisted-pair telephone topologies. Information propagates around the logical ring, reaching every device on each revolution around the network. Network devices are full-duplex, transmitting and receiving information on every clock cycle. Network devices arbitrate to be elected the network clock device. By synchronizing all network devices to a single reference clock, and providing fixed frames of information propagating around the network at consistent time intervals, the logical ring network ensures that information propagates from one device to another at consistent time intervals. The fixed-length frames are divided into two independent streams: a data stream for the distribution of real-time continuous digital media streams; and a system command stream for the distribution of system commands.

Ordered-element naming for name-based packet forwarding
ActiveUS20140289325A1Easy to determineEasy pairingDigital data processing detailsDigital computer detailsComputer scienceFixed length
A name-based content-forwarding system generates an ordered-element name for a content item, and can process an interest to identify and perform an action that satisfies the interest. To generate the ordered-element name, the system generates one or more fixed-length elements for a content item, such that each fixed-length element of the ordered-element name is mapped to the content item or to a context associated with the content item. The system then generates the ordered-element name to include the one or more fixed-length elements so that the name elements are ordered from a highest matching priority to a lowest matching priority. The system can also generate a packet that includes the ordered-element name for the content item, and sends the packet to a target location that corresponds to the ordered-element name.

When flow is allowed to pass through the valve prosthesis device from the inlet to the outlet, the valve assembly is kept in an open position, whereas a reverse flow is prevented as the collapsible slack portions of the valve assembly collapse inwardly providing blockage to the reverse flow. The device is configured so that retrograde flow will be altered from laminar flow and directed towards the leaflets to effect closing.

System for forwarding a packet with a hierarchically structured variable-length identifier
ActiveUS8160069B2Data switching by path configurationStructure of Management InformationLongest prefix match
One embodiment provides a system that receives a packet with a hierarchically structured variable-length identifier (HSVLI). An HSVLI indicates a piece or collection of content and may be hierarchically structured, comprising contiguous components ordered from a most general level to a most specific level. The length of a respective identifier is not fixed. During operation, the system converts the HSVLI into a fixed-length key. Subsequently, the system obtains forwarding information based on one or more longest-prefix matches with a longest-prefix-match lookup engine using the fixed-length key. Next, the system forwards the packet to an output port based on the forwarding information.

Efficient motion vector coding for video compression
InactiveUS6983018B1Code motion vectors more efficientlyLengthen codePicture reproducers using cathode ray tubesCode conversionVariable-length codeVideo encoding
Video coding efficiency is improved by jointly coding the x and y components of motion vectors with a single variable length code. The motion vector components for a block of pixels are predicted based on motion vectors of neighboring blocks of pixels. The predicted x and y components are then jointly coded by assigning a single variable length code corresponding to the pair of components, rather than a separate code for each component. If the x and y components do not have a corresponding entry in the coding table, they are coded with an escape code followed by fixed length codes.

Method for adding and encoding error correcting codes and its device and method for transmitting data having error correcting codes added
A method for encoding error correcting codes to generate plural coded data having different error correction ability according to significance. An error correcting code having different code length is added to a fixed length of input data according to the significance of the input data (S14). The error correcting codes added which have different error correction ability corresponding to its code length are encoded to generate coded data having different packet length according to the code length of the error correcting code. Thus, plural coded data (S15A and S15B) which have different error correction ability according to significance can be generated. Thereby, even if a quality of transmission system deteriorates when the above coded data is transmitted, the coded data having high error correction ability can be surely decoded.
