Abstract: A message is multicast to recipients by correlating the message at a management system to agents, each agent being responsible for a set of the recipients, and by conveying the message over a network to the correlated agents for transmission to the recipients.  The management system maintains recipient lists wherein each list is associated with one or more agents, each agent maintaining a portion of its associated lists. The management system chooses a single recipient list and conveys an indication of the list to its associated agents.  Each notified agent accesses the indicated list and sends the message to the listed recipients. In a further embodiment, an independent management system interfaces a plurality of management systems, each with a set of agents. The independent management system chooses a recipient list, the list being associated with a management system and its agents, and conveys the message based on the chosen list.

Title: Micromachined inertial sensor for measuring rotational movements
Inventor: LEVERRIER BERTRAND
IPC: G01C19/56
Filed: 2002-12-10
Abstract: The invention concerns rate gyros with micromachined oscillating system in a silicon substrate. The invention discloses an original oscillating system with two mobile masses (14 and 14'), linked by a vibrational energy coupling structure ( transverse arms (26, 26'), longitudinal arms (22, 22'), and short transverse attachment (24) between the longitudinal connections (22, 22')). The mobile masses are further suspended to U-shaped flexural arms (13) having one branch end linked to the mass and another end linked to a fixed anchorage point (18). The flexural arms are not interposed between the coupling structure and the mass but are independent of the coupling structure. The masses are excited in vibration in their plane by electrostatic forces applied with interdigital parts (11). The Coriolis forces cause them to vibrate perpendicularly to the plane and said vibration is detected by electrodes forming part of the mobile masses. The invention is useful for measuring angular speeds in aeroplanes, motor vehicles, robots and the like.

Patent CA-2471378-A1 (CA)
Inventor: RUECKES THOMAS
IPC: H01H59/00
Filed: 2002-12-19
Abstract: Three trace electromechanical circuits and methods of using same are described. A circuit includes first and second electrically conductive elements with a nanotube ribbon (or other electromechanical elements) disposed therebetween. The nanotube ribbon is movable toward at least one of the first and second electrically conductive elements in response to electrical stimulus applied to at least one of the first and second electrically conductive elements and the nanotube ribbon. Such circuits may be formed into arrays of cells. The upper and lower electrically conductive traces may be aligned or unaligned vertically. An electrical stimulus may be applied to at least one of the first and second electrically conductive elements and the nanotube ribbon to move the nanotube ribbon toward at least one of the first and second electrically conductive elements. Electrical signals from at least one the first and second electrically conductive elements and the nanotube ribbon may be sensed to determine the electrical state of the cell. The states may be assigned in a variety of ways. For example, if the ribbon is moved toward the first electrically conductive element, the electrical state is a first state, if the ribbon is moved toward the second electrically conductive element, the electrical state is a second state, and if the ribbon is between the first and second electrically conductive elements, the electrical state is a third state. The first, second, and third states each corresponds to a different information encoding. Or, electrical stimulus may be applied to both the first and second electrically conductive elements so that the first and second electrically conductive elements both cause the movement of the nanotube ribbon. Or, the first and second electrically conductive elements are used in a fault tolerant manner.

Title: In situ biodegradation of subsurface contaminants by injection of phosphate nutrients and hydrogen
Inventor: PRIESTER LAMAR E III
IPC: C12S9/00
Filed: 2003-03-25
Abstract: The present invention provides a method and gaseous composition for the in situ bioremediation of soil and groundwater contaminated with organic compounds, including halogenated hydrocarbons. The gaseous composition, which readily permeates a subsurface region, comprises hydrogen (H2(H2)and one or more vo latile phosphates, such as triethylphosphate (TEP) and tributylphosphate (TBP).

Title: Bipolar plate for a fuel cell
Inventor: DOHLE HENDRIK
IPC: H01M8/02
Filed: 2003-06-28
Abstract: The invention relates to a bipolar plate for a fuel cell, especially a low temperature fuel cell comprising a centre plate, at least one intermediate plate comprising a recess for the flow distribution of an operating medium and at least one cover plate which is adjacent thereto and which has at least one recess. The centre plate and the cover plates can be made of metal, plastic or graphite.

The cover plate advantageously prevents the membrane-electrolyte-unit (MEA) from pressing into the bipolar plate. The inventive modular bipolar plate enables an extremely compact structure to be obtained.  Space-saving fuel cell stacks can be obtained, wherein the layer thickness of an individual bipolar plate (centre plate, two intermediate plates, two cover plates) is as a rule significantly less than 1.4 mm, advantageously less than 1.0 mm.
