    摘要: Electrical power is produced by a first process component, a first heat pipe formed in part by a first cavity within the first process component, and a thermoelectric generator assembly. The thermoelectric generator assembly is thermally coupled on one side to a heat sink and on the other side to the first heat pipe. The first process component is in direct contact with a first process fluid and the first cavity is proximate the first process fluid. The thermoelectric generator assembly produces electrical power.

    摘要: An aspiration catheter comprises a catheter body having an aspiration lumen therethrough. The distal opening of the aspiration lumen can be modified in various ways or can have the addition of structure in order to disrupt sealing between the port and material being aspirated. Examples of modifications include slots, castellations, zig-zag features, and other geometries which resist sealing of aspirated material. Blades, rollers, vibrating elements, and other structures may be provided within or around the distal end of the aspiration lumen in order to dislodge and disrupt aspirated material which can seal against the opening.

    摘要: A system for measuring and analyzing radio frequency power proximate and within a wireless field device mesh network. A centralized software module (CSWM) collects and analyzes values from one or more wireless devices of the wireless field device mesh network representing received RF power measurements on an assigned RF channel and values representing corresponding times of the received RF power measurements. Each wireless device measures received RF power on the assigned RF channel at times other than during reception of a signal resulting in transmission by the wireless device of either an acknowledgment signal or a non-acknowledgement signal. Values representing the received RF power measurements and the corresponding times of the received RF power measurements are determined from the stored received RF power measurements and corresponding times and then discarded. These values are stored within the wireless device until successfully reported. A network manager coordinates communication between the wireless devices and synchronizes the corresponding times of received RF power measurement throughout the wireless field device mesh network.

    摘要: A wireless mesh network that makes use of strategically placed nodes with radios having superior communication range through the use of high gain antennas, MIMO technology, high power transmitters, high sensitivity receivers, a combination thereof, etc. Besides the obvious effect of extending the physical coverage area of a network, the effect of the longer distance links formed by the nodes with superior range is a flattening of the wireless mesh network by reducing hop count, thereby improving performance, latency, reliability, cost, and power consumption among other factors.

    摘要: An apparatus for bridging a barrier to wireless communication between wireless field device networks includes a pair of locally-powered wireless devices connected by a wired link spanning the barrier. At least one of the locally-powered wireless devices is in wireless communication with each of the wireless networks intended to be interconnected. The wireless devices include a wireless transceiver and an antenna. Messages from one wireless field device network addressed to a member node of another wireless field device network are received by a wireless device on one side of the barrier and transmitted via the wired link to another wireless device on the other side of the barrier for routing to the member node of the other wireless field device network.
