  • Publication number: 20050130580
    Abstract: An air-distribution system for the dashboard of a motor vehicle comprises a plurality of auxiliary ducts that branch off in parallel from a manifold. Associated to each auxiliary duct is an additional and independent unit for regulating the flow rate and/or the temperature of the air flow that traverses the respective auxiliary duct. Each auxiliary duct branches off into a number of terminal ducts and is provided with means for the distribution of the air to the terminal ducts, which are preferably of the type comprising means of deviation of the air by the Coanda effect.

  • Publication number: 20050130579
    Abstract: Described herein is a Coanda-effect air distributor for distributing a flow between a number of ducts set downstream. Provided in the area that separates the initial ends of two ducts set downstream is the inlet of a recirculation duct that creates an air circulation that masks the entrance of a duct set downstream when the flow is deviated into the other duct.

  • Patent number: 6835083
    Abstract: An actuator including a shape-memory flexible cable with a flexible sheath can be used, by controlling it both electrically and mechanically using the sheath as element for applying a mechanical tensile force. The shape-memory flexible cable is provided with a coating made of synthetic or elastomer material moulded thereon and adherent thereto, which favors rapid return of the shape-memory cable into its resting configuration after its activation both on account of its elastic return and owing to the fact that it favors cooling of the cable. Preferably, the coating is obtained by means of a process of co-extrusion with the shape-memory cable.

  • Patent number: 6792976
    Abstract: A fluid distribution system comprised of an inlet duct (1) and two outlet ducts (6 and 7) including deviating means for directing the inlet flow into one or the other outlet ducts (6 and 7) composed of a mobile wall (2) suitable for making the flow adhere to the walls of one duct or the other due to the Coanda effect. In a first position, the mobile wall (2) is incorporated into the side wall (3) of the inlet conduct (1) that extends into one of the two outlet ducts. From this position, the mobile wall (2) can be moved to a second position where its upstream end protrudes inside the duct to create a step-like irregularity (4) on the duct's internal surface.

  • Patent number: 6762669
    Abstract: A shape memory actuator includes a shape memory actuator element for biasing an actuated member from an initial rest position to an operative position against the action of return spring means. Holding means are associated with the actuator element for holding the actuated member in its operative position even when the shape memory actuator element is deactivated. These holding means can be deactivated with a subsequent activation of the shape memory actuator element, allowing the actuated member to return to its rest position.
