Abstract: A lock mechanism is disclosed for a sheet store adapted for the dispensing or accepting of sheets. The sheet store comprises a container having a lid operable for access to the interior of the container and a shutter operable for the passage of sheets therethrough. The lock mechanism comprises: a locking plate movable relative to the container, the locking plate being operable to control a lid lock element and a shutter lock element; and an actuator arranged to control movement of the locking plate. The locking plate is movable between three positions, including: a closed position, in which the shutter lock element prevents opening of the shutter; a primed position, in which the shutter can be opened; and an open position which controls the lid lock element to permit opening of the lid.

Abstract: A bookmarking system is described for allowing users to bookmark audio and video content for sharing with other users. The system allows the bookmark to be generated with minimal user involvement, making the process as easy to use as the bookmarking of websites on a computer device. A disambiguation server is provided to disambiguate the content to be book-marked. The disambiguation server uses information from various sources to provide a number of candidates for selection by the user. Historical data and the bookmarks of other users can also be used to aid the disambiguation process.

Abstract: A cellular telephone is provided for recovering hidden data that is embedded within an input acoustic signal. The telephone passes the acoustic signal through an audio coder of the telephone and then processes the compressed audio generated by the audio coder, to recover the hidden data. A similar telephone is also provided for identifying the audio signal from the compressed output of the audio coder. Various coding techniques are also described for hiding the data within the audio.

Abstract: There is described a number of encoders for encoding a data signal within an audio signal. In some of the encoders, the audio signal is separated into a tonal part and a residual part, and the data signal is shaped based on the residual part. In other encoders, the data signal is separated into a tonal part and a residual part, and the data signal is combined with the audio signal independence upon the residual part. In other encoders, the rate at which the data is encoded within the audio signal is varied in dependence upon the audio signal. There are also described various decoders associated with the described encoders.

Abstract: A client server system (100, 200, 300) comprises a client subsystem (100), a server subsystem (200) and an interconnecting data network. The client subsystem includes a client application (110, 120, 130, 140, 150) operable to initiate a secure connection over the interconnecting network with the server subsystem (200). The server subsystem includes a server application (254, 255, 256, 257), which is operable to co-operate with the client application to complete the setting up of a secure connection with the client application upon initiation of the connection by the client application and which is further operable to transmit output data over such a connection in response to requests for service provided by the client application.

Abstract: A client-side intermediary (30) is provided to balance the loading of Web service requests between a plurality of servers (32). The status of the Web service servers (32) is monitored by a monitoring server (35) which provides status updates to the intermediary (30) upon request. The intermediary then uses the information on the status of the servers (32) to decide where to send web service requests. Additionally, the intermediary is able to direct requests for Web service descriptions to the least busy server on the basis of status information. The intermediary (30) substitutes its own identifier for the service name and port in the Web service description before passing it to the client so that all requests are directed through it, thus allowing the continual provision of service for the client even in the event that one of the servers fails.

Abstract: A method for making a braze joint across a discontinuity in a work piece using alternating current. A filler metal is pre-placed at a location sufficiently close to the discontinuity such that, when an alternating current is applied across a work piece to heat the work piece and melt the filler metal, the filler metal is drawn into the discontinuity. The alternating current is maintained for a set residence time, generally less than 10 seconds and more particularly less than 3 seconds. The alternating current is then altered, generally by reducing the current and/or voltage such that the filler metal can solidify to form a braze joint of desired quality and thickness.

Abstract: A document feeder comprises an input hopper (1) into which batches of documents with interleaved separators (24, 25) are loaded in use, each separator carrying data related to the associated batch. A feed system (9, 10) withdraws documents and separators singly from the input hopper. A sensing system (7) obtains information about the documents and separators. The sensing system includes a data sensor (7) located so as to read separator data while the separator (24, 25) is in the input hopper (1).

Abstract: A capillary test specimen, method, and system for visualizing and quantifying capillary flow of liquids under realistic conditions, including polymer underfilling, injection molding, soldering, brazing, and casting. The capillary test specimen simulates complex joint geometries and has an open cross-section to permit easy visual access from the side. A high-speed, high-magnification camera system records the location and shape of the moving liquid front in real-time, in-situ as it flows out of a source cavity, through an open capillary channel between two surfaces having a controlled capillary gap, and into an open fillet cavity, where it subsequently forms a fillet on free surfaces that have been configured to simulate realistic joint geometries. Electric resistance heating rapidly heats the test specimen, without using a furnace.
