Abstract:

A provisioning system includes an interactive display that provides graphical feedback to a craft worker, or user. The interactive display indicates to the user possible provisioning schemes and may also indicate actually provisioned paths. Graphical templates provide a visual indication of provisioning topologies and a variety of interactive display techniques, such as pull down menus, dialog boxes, color coding, icons, and affordances, for example, may be employed in conjunction with the graphical templates to provide visual cues regarding network provisioning to a user. A wizard may be employed to step a user through the provisioning process.

A61M005/178
A61M005/00

US Classification:

604158, 604239, 604264

Abstract:

A catheter introducer includes a tube having a proximal end, a distal end and a lumen extending therethrough along a longitudinal axis of the tube for accommodating a catheter traveling along a longitudinal axis of the tube and a head portion coupled to the distal end of the tube. The head portion includes an aperture in fluid communication with the lumen at a proximal end thereof and a tip at a distal end thereof, an exterior surface extending from the proximal end thereof to an opening of the head portion along a first portion of the head portion and extending from the proximal end thereof to the tip along an opposing portion of the head portion and an interior surface extending from the aperture to the opening of the head portion along the first portion of the head portion and extending from the aperture toward the tip along the opposing portion of the head portion. The exterior surface circumferentially tapers from the proximal end to the distal end and the interior surface forms a channel for receiving a catheter passing through the lumen and the aperture, the channel being concave along at least one axis.

US Classification:

604 8, 604 9601, 60410001, 60410308, 604919

Abstract:

A shunt includes a first occlusion assembly and a second occlusion assembly. The first occlusion assembly includes a first occlusion fluid conduit that carries an inflation fluid from a fluid source to a first balloon of the shunt. The second occlusion assembly includes a second occlusion fluid conduit that carries an inflation fluid from a fluid source to a second balloon of the shunt. The first occlusion assembly includes a first color and the second fluid assembly includes a second color, distinct from the first color. The distinctive colorings of the first and second occlusion fluid conduits remain visible within an operative field during an endarterectomy procedure and allow a user to distinguish the first occlusion assembly from the second occlusion assembly during the procedure.

International Classification:

A61B 5/0205

US Classification:

600508

Abstract:

A load score system includes a metabolic sensor such as a heart rate sensor for a subject is configured to output metabolic data for the subject. A biomechanical load sensing subsystem for the subject is configured to output biomechanical load data. A speed sensor subsystem for the subject is configured to output speed data. One or more databases store zones and a weighting factor for each zone for metabolic data, biomechanical load data, and speed data. A performance module is responsive to the metabolic data, the biomechanical load data, and the speed data and the one or more databases and is configured to calculate a metabolic load score for the subject. A biomechanical load score for the subject and a speed load score for the subject are also calculated. An output module displays the subject's calculated metabolic, biomechanical, and speed load scores.

David McDonald - Arlington MA, US

International Classification:

G10L015/04

US Classification:

704/251000

Abstract:

A method for constructing a dynamic vocabulary for a speech recognizer used with a database of indexed documents. Key words are first extracted from each of the documents in the database as the documents are indexed. The extracted key words are than used to dynamically construct the vocabulary of the speech recognizer or a search engine.

Appl. No.:

10/395929

Inventors:

David McDonald - Arlington MA, US

International Classification:

G06F017/27

US Classification:

704/009000

Abstract:

A method filters natural language output including fixed phrases by determining sequentially, for each fixed phrase, whether the fixed phrase has occurred in a discourse history. The fixed phrase is passed to a target component if the fixed phrase does not occur in the discourse history. If the fixed phrase does occur in the discourse history, a subsumption lattice is searched for an expressive type associated with the fixed phrase that is licensed in a context of the discourse history. The fixed phrase is converted to a filtered phrase according a realization method of the licensed expressive type and the filtered phrase is passed to the target component.
