    摘要： A wireless bridge device disposed within a process control system provides wireless communication between multiple devices within the process control system, such as between field devices, control units, user terminals, controllers, etc. In one embodiment, a process control system disposed within an industrial process environment includes a first process control device, a bridge device, a plurality of field devices disposed within the industrial process environment and a hardwired communication link disposed between the bridge device and each of the plurality of field devices. A wireless communication network including a first wireless transceiver located at the first process control device and a second wireless transceiver disposed at the bridge device enables the bridge device to operate to relay signals sent over the hardwired communication link from any of the plurality of field devices to the first process control device using the wireless communication network and to operate to relay signals sent over the wireless communication network from the first process control device to one or more of the plurality of field devices using the hardwired communication link.

    摘要： An apparatus provides wireless communication between multiple devices within a process control system, such as between field devices, control units, user terminals, controllers, etc., using a wireless bus protocol. In one embodiment, a process control system for use within a process control environment includes a plurality of process control field devices that operate within the process environment, and a control device adapted to receive a sense signal from or to provide a control signal to one or more of the plurality of process control field devices. First and second wireless transceivers are communicatively connected to different ones of the process control field devices and the control device and communicate with one another using a bus protocol, to thereby provide wireless communications within the process control system.

    摘要： A card guide apparatus for retaining a PCI or ISA computer add-on card within a computer chassis frame. The card guide includes a bracket fixed to the computer chassis frame and a shuttle that is moveable between a first position disengaged with edges of the card to a second position engaged with the edges of the card for support during transport. The shuttle is slidably retained along at least one track defined within the bracket and includes an upper and lower panel defining a channel therebetween in which the card edge is received.
