Abstract:
aparelho para interconexão de redes sem fio separados por uma barreira. trata-se de um aparelho para interligar em ponte uma barreira à comunicação sem fios entre redes sem fios de dispositivos de campo que inclui pelo menos um par de dispositivos sem fios alimentados localmente conectadas por uma ligação com fio que transpõe a barreira. pelo menos um dos dispositivos sem fios alimentados localmente está em comunicação sem fio com cada uma das redes sem fio que deverão ser interconectadas. os dispositivos sem fio incluem um transceptor sem fio uma antena. as mensagens de uma rede sem fio de dispositivos em campo endereçadas a um nó membro de outra rede de dispositivos de campo sem fio são recebidas por um dispositivo sem fio em um dos lados da barreira e transmitidas através da ligação com fios a um outro dispositivo sem fios do outro lado da barreira para roteamento ao nó membro da outra rede de dispositivos de campo sem fio.
Abstract:
A wireless field device assembly comprises a process sensor, a housing, a power module, and a processor. The process sensor is configured to monitor a process variable and produce a sensor signal. The housing encloses an interior space of the wireless field device. The power module comprises an energy storage device and a connection to a local power source, and is configured to be housed in the wireless field device. The processor is located within the interior space, and is powered by the power module. The processor produces a fault signal value used to differentiate between energy storage device faults, local power source faults, and no-fault states.
Abstract:
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.

Abstract:
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.
Abstract:
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.
