摘要:
A network architecture for implementation in a vehicle is described that comprises an Ethernet gateway module (EGM) and network interface module (NIM). The EGM comprises an Ethernet switch and router therein and is configured to provide an open data network (ODN) connection to the network architecture for a plurality of open data network devices. The NIM is configured to provide an isolated data network and comprises an Ethernet switch to connect a plurality of secure devices to an isolated data network (IDN), the secure devices related to operation and navigation of the vehicle, a router and a gateway/router. The router is configured to interface the IDN to the open data network connections and comprises a packet filtering function to determine which, if any, data from the ODN may be passed through to the IDN and applied to operation and navigation of the vehicle via the secures devices connected to the IDN. The gateway/router provides network address and protocol translation to connect the IDN to a secure common data network associated with vehicle operation. The architecture provides segregation between network devices in the IDN and CDN related to operation and navigation of the vehicle, and network devices in the ODN.

The present invention relates generally to the field of primers and adhesion promoters. More specifically, the primer of the present invention is comprised of one or more multi-carbonylated methacrylates. In a preferred embodiment, a non-ketone polar solvent is also employed. The resulting composition eliminates primer related discoloration of artificial nail enhancements, eliminates the potential for corrosion of skin and nails, and eliminates risk of chemical burn injury, while providing stronger adhesion than currently available primers.

A cluster of computer system nodes connected by a storage area network include two classes of nodes. The first class of nodes can act as clients or servers, while the other nodes can only be clients. The client-only nodes require much less functionality and can be more easily supported by different operating systems. To minimize the amount of data transmitted during normal operation, the server responsible for maintaining a cluster configuration database repeatedly multicasts the IP address, its incarnation number and the most recent database generation number. Each node stores this information and when a change is detected, each node can request an update of the data needed by that node. A client-only node uses the IP address of the server to connect to the server, to download the information from the cluster database required by the client-only node and to upload local disk connectivity information.

The invention relates generally to expandable medical implants for maintaining support of a body lumen and, in particular, to an axially nested, diametrically expandable, slide and lock vascular device for enlarging an occluded portion of a vessel. The axially nested vascular device desirably achieves both competitive crossing profiles while maintaining other key features, such as, for example, radial strength and luminal patency. The collapsed profile can also be made very thin without compromising radial strength. Thus, the vascular device can advantageously be deployed in small and difficult to reach areas or vessels. The axial nesting substantially eliminates radial overlap between mating structural elements thereby desirably allowing for a low, uniform profile.

A method for controlling a lamp circuit that includes: setting a first voltage threshold and a first time window within a control circuit corresponding to a characteristic of a first lamp type; providing a first signal through the lamp circuit to start a first time interval and create a first test voltage; comparing the first test voltage to the first voltage threshold; and operating a switch to couple an output of the lamp circuit to a source of electrical power if the first test voltage is greater than or equal to the first voltage threshold before the first time interval exceeds the first time window.

A pump includes a flexible conduit, at least one valve attached to the flexible conduit about the perimeter of the valve; and a drive mechanism to move the valve to pump blood within the conduit. The drive mechanism can, for example, be adapted to complete a single stroke during each heart ventricle contraction and/or to complete multiple strokes (that is, oscillate) during a single contraction. Another implantable pump for assisting blood flow, includes: a flexible conduit formed in an arc; at least one movable valve in operative connection with the conduit; and a drive mechanism to move the valve in an arced path to pump blood within the conduit. Another pump includes a conduit and at least one moveable valve within the conduit. The moveable valve includes a plurality of openings. Each of the plurality of openings has a closure mechanism in operative connection therewith. Each closure mechanism is operable to at least partially close the opening to which it is operatively connected when the moveable valve is moved forward and to open the opening to which it is operatively connected when the valve is move rearward. The pump further includes a drive mechanism to move the valve to pump blood within the conduit. In one embodiment, each closure mechanism includes a flap of resilient material.

摘要:
An apparatus for forming a wave form for a stent from a wire includes a first forming member configured to move substantially parallel to a first axis and to move substantially parallel to a second axis that is orthogonal to the first axis, and a second forming member configured to move substantially parallel to the first axis and to move substantially parallel to the second axis. The second forming member is positioned opposite from the first forming member relative to the second axis along which the wire is configured to travel. The apparatus includes a controller configured to control movement of the first forming member relative to the wire and to control movement of the second forming member relative to the wire so that the first forming member and the second forming member deform the wire in opposite directions to form a portion of the wave form.
