Granted: 2005-09-13
Abstract: Biodegradable shape memory polymer compositions, articles of manufacture thereof, and methods of preparation and use thereof are described. In one embodiment the compositions include at least one hard segment and at least one soft segment. The T trans of the hard segment is preferably between -30 and 270 .degree.C. At least one of the hau l or soft segments can contain a cross-linkable group, and the segments can be linked by formation of an interpenetrating network or a semi - interpenetrating network, or by physical interactions of the segments. Objects can be formed into a given shape at a temperature above th e T trans of the hard segment, and cooled to a temperature below the T trans of the soft segment. If the object is subsequently formed into a second shape, the object can return to its original shape by heating the object above the T trans of the soft segment and below the T tra ns of the hard segment.

Abstract: A data transfer method includes receiving terminal server identification data at a host system from a terminal server, querying a database to obtain localized information service data associated with the terminal server identification data, and sending the localized information service data from the host system to the terminal server. A host system providing localized information system data includes a database system, a network interface, and a processor. The database system includes records to associate terminal server identification data with information service data. The interface couples the host system to a communications link over which the host system can exchange data with a terminal server. The processor is coupled to the interface and to the database and is configured to receive terminal server identification data from the data interface, to query the database for localized information service data associated with the terminal server identification data, and to send the localized information service data obtained by the query to the data interface for transmission to the terminal server.

Filed: 2001-01-02
Granted: 2008-03-25
Abstract: A metal cutting process employs an apparatus including a cutting machine operable to cut two dimensional profiles in plates. The plates are transported to and from the cutting machine on carriages. The carriages are movable between a cutting, or burn position , an un-loading position, and a loading, or re-loading position along a path. The path forms a closed circuit, or loop. In the burn position the cutting machine is operable to cut profiles in the plates. Cutting on one carriage can occur while another carriage, or other carriages, are being loaded or unloaded, or both. The carriages can be cylced along the path repeatedly. The apparatus can include a de-coiling machine for un-coiling coils of steel sheet, and the process can include uncoiling a steel sheet directly onto one of the carriages. The process can also include cutting a steel sheet in a single piece to form the side of a large structure, such as a rail road car.

Abstract: A liquid dispenser (1) comprises a housing (2) and a hook (3) for suspending the housing (2) from the rim of a lavatory bowl. A user inserts a sealed inverted reservoir bottle (6) into the housing (2), which breaks the seal. A porous pad (7) located in the housing (2) conveys liquid from the bottle (6) to a position within the stream of flushing water. The pad (7) can be adjusted to accommodate different lavatories and has two guide slots which are engaged by two fingers in the housing which define two extreme positions of the pad (7). To allow venting of the bottle (6), small vent holes (14) are formed in the pad (7). The pad may alternatively be a solid plate of the same shape but having a number of raised holes or elongate slots. The plate may have a venting post which mates with the mouth of the bottle (6). Venting may be achieved by providing an aperture in the bottle. The top of the bottle may be; provided with: a one-way valve; with a plug which seals the aperture, the housing having a pin which bears on the plug and releases it into the bottle; a breakable seal which covers the aperture, the housing being provided with a tube member which seals the aperture; or a removable tab which covers the aperture and which is broken away from the bottle prior to insertion, either by the user or, automatically, by a projection within the housing.

Abstract: An electronic circuit for measuring the position of a spatially periodic intensity pattern of incident radiation includes an array of detectors (1); two or more correlator units (2,3) each having arrays of capacitors (12,13) connected to a buffer (14); and a phase angle computing unit (4). The pitch of the array of detectors (1) is smaller than the pitch of the incident intensity pattern so that the latter is oversampled, yielding high accuracy. The detector outputs (17) are weighted by respective fixed capacitance values (15, 16) which vary periodically along arrays of capacitors (12,13), and a weighted sum of outputs for each correlator unit (2,3) is output at its respective buffer (14). The capacitance values (15,16) of respective correlator units (2, 3) are mutually offset by a predetermined phase shift. The analog computation using capacitor arrays (12,13) is fast and energy efficient, and can be implemented as a VLSI circuit.

Abstract: L'invention concerne un réseau offrant à des utilisateurs une manière simple et sûre d'établir des communications avec d'autres utilisateurs ou services, fonctionnant su des réseaux IP ou d'autres réseaux tels que le RTPC. On prévoit une pluralité de groupes différents de serveurs et chaque groupe peut y être relié. Les utilisateurs sont enregistrés dans un groupe spécifique et on leur attribue un ID système/réseau unique. Les messages ne sont pas envoyés directement entre utilisateurs mais à travers au moins un service de routage intermédiaire (RS) dont est équipé le serveur d'un des utilisateurs. Ainsi, un utilisateur peut cacher ou masquer des informations personnelles même lorsqu'il est en communication avec d'autres utilisateurs. Selon certains modes de réalisation, un utilisateur peut établir une liaison avec un autre utilisateur sans connaître le périphérique client (PC, téléphone portable, etc.) qu'utilise l'autre utilisateur, alors que le réseau est prêt pour la communication (p. ex. forum de discussion sous forme de texte, forum de discussion sous forme d'échanges vocaux (de PC à PC, de PC à RTPC ou de PC à téléphone portable), conférences sur le web ou pages (de PC à PC, de PC à SMS)) entre les utilisateurs quel que soit le périphérique client utilisé par l'utilisateur appelé. L'utilisateur qui lance l'appel n'a pas besoin de savoir si l'autre utilisateur est actuellement en ligne via son PC ou peut être joint par pageur ou téléphone portable.
