Abstract: Various communication systems may benefit from appropriate filtering of communications. For example, a network having a broadcast bus, such as a controller area network, may benefit from a frame filter. For example, a method can include receiving a plurality of messages at an interface with a broadcast bus of a communication network for a system. The method can also include selectively permitting the plurality of messages to be conveyed through the interface based on comparing one or more of the plurality of messages to a specification for the interface.

Abstract: The Advanced Encryption Standard (AES) cipher can be performed in a manner that preserves the secrecy of cryptographic keys, even under the intense scrutiny of a reverse-engineer observing every aspect of the computation. A method can include loading a key in a non-standard representation. The method can also include processing the key with respect to data in at least three first type rounds and a plurality of second type rounds. The processing the key with respect to data can include either encrypting the data using the key or decrypting the data using the key. The first type rounds can be configured to maintain an order of channels of bits at an output from the order of corresponding channels of bits at an input. The second type rounds can be configured to vary the order of channels of bits at an output from the order of corresponding channels of bits at an input.

Abstract: A dispersion apparatus for dispersing a treating agent into a fluid treatment system that includes a flow duct in which a fluid stream flowing through the duct is mixed with the treating agent. The apparatus is based on a multi-pipe lance positioned in the stream flow, where each pipe supplies a minimum of feed discharge nozzles (typically one to four), and the individual pipes branch off from the same location. Use of the multi-pipe lance, in combination with a suitable baffle, results in better overall dispersion/distribution of the injected medium by surface area. By improving the surface area distribution, better utilization of the injected sorbent can be achieved. The baffle acts to generate a low pressure zone on its downstream side and creates a high-intensity turbulence plume in the fluid. The orifices of the pipe are located to inject the treating agent into the turbulence plume to better distribute and intermix the injected treating agent into the surrounding fluid.

Abstract: A dispersion lance is for use in combination with a fluid treatment system of the type which includes a flow duct in which a fluid stream is mixed with a treating agent. The dispersion lance includes a pipe mounted in the duct with its axis approximately transverse to the direction of the fluid stream flow, the pipe having a series of openings along its length for injecting a treating agent into the fluid stream. A baffle extends lengthwise along the pipe, the baffle having a cross-section the central portion of which is V-shaped, with the apex of the V facing upstream of the fluid stream flow, and with generally flattened wing portions extending from the legs of the V beyond the sides of the pipe in a direction where they transversely intersect the stream flow. The baffle acts to generate a low pressure zone on its downstream side which enhances turbulence in the fluid.

Abstract: A card creation method and system includes defining a data entry screen including a plurality of screen fields and creating at least one card layout, including defining specific positions for a plurality of card fields. Data is input into the screen fields using the data entry screen, and then transferred to a one of the card layouts to create the card. The data entry screen definition and the card layouts may be saved prior to inputting data. Still further, a data source having at least one data field may be identified for providing data, and a screen field may be linked to a data field. Data from the data field is copied to the linked screen field. Additionally, a card filed may be linked to a selected screen field. The created card may be saved and/or printed. Thus, a user is able to create customized data entry screens, as well as custom card designs.

Abstract: An in-flight entertainment system provides live video/audio programming to passengers and operators over an aircraft video/audio distribution system. The programming signals are derived from intermediate frequency (IF) signals that are produced by frequency downconverting satellite broadcast signals and supplied over a pair of IF signal output cables. The control signals and the DC power used in the frequency downconversion process are received over the same IF signal output cables, but in a reverse direction. A bias-T connector is provided in each of the IF signal output cables to extract out the control signals and the DC power.

Abstract: An in-flight entertainment system provides live video/audio programming to passengers and operators over an aircraft video/audio distribution system. The programming signals are derived from satellite broadcast signals that may be in either circular polarized form or linear polarized form. The broadcast signals are collected by two probes and extracted as right and left circular polarized signals. The right and left circular polarized signals are converted into either circular or linear polarized IF signals, and the IF signals are processed by a receiver/decoder unit to produce the live video/audio programming signals.

Abstract: The present invention describes a time based servo pattern scheme which provides position and velocity information with high accuracy. A plurality of servo lines are formed on a data disk extending from the inner track to the outer track. In the preferred embodiment of the present invention, these lines are employed as part of a buried servo scheme such that the entire useable disk surface is dedicated to data storage. The servo pattern is written on each side of the disk so that, if the disk were transparent, the respective servo lines would appear to intersect when viewed from above. Servo heads located on each side of the disk detect servo line crossings. By comparing the time difference between crossings of corresponding tracks on either side of the disk, the radial position of the heads can be determined. Therefore, even when nominal track centers do not fall on servo line intersections, their position can be determined accurately.
