    Abstract: A piezoelectric fluid pressure fluctuation frequency sensor, preferably for a vortex-shedding flowmeter. A piezoelectric transducer is located in a sensor chamber between and in physical contact with a diaphragm and a chamber surface. Pressure fluctuations in a von Karman vortex street outside the diaphragm compress the transducer, between the diaphragm and the chamber surface. The transducer generates a responsive electrical signal which is representative of the pressure fluctuations.

    Abstract: An improved flow meter and sensor body therefor, the body having a strain relief portion. A housing of the flow meter defines a fluid flow passage and a sensor body opening. A sensor body mounting portion is mounted to the housing. A sensor body sensor supporting portion is in the fluid flow passage, and supports flow sensor transducers in the fluid flow. The sensor body relief portion is intermediate the sensor body mounting and supporting portions, in the sensor body opening, and adapted to relieve induced strain from external vibration, whereby the flow meter is substantially insensitive to external vibration.

    Abstract: An identification card printer for printing an image on an identification card, is provided which includes a print mechanism adapted to deposit material on to the card. A network adapter is configured to couple to a network. A print drive module controls the print mechanism in response to a drive module input. A client/server module is coupled to the network adapter and functions as a client on the network to responsively provide data to the drive module input. The client/server module can further function as a server on the network to serve data to the network.

    Abstract: A two-wire field-mounted process device with multiple isolated channels includes a channel that can be an input channel or an output channel. The given input or output channel can couple to multiple sensors or actuators, respectively. The process device is wholly powered by the two-wire process control loop. The process device includes a controller adapted to measure one or more characteristics of sensors coupled to an input channel and to control actuators coupled to an output channel. The controller can be further adapted to execute a user generated control algorithm relating process input information with process output commands. The process device also includes a loop communicator that is adapted to communicate over the two-wire loop.

    Abstract: A ribbon for a thermal printer has a series of frames of different colors in a sequence that are correlated to the position of cards to be printed. The ribbon has indexing marks for each frame and also indicators for each repeating sequence of frames. The index marks are arranged in a line across the ribbon and the marks can be coded to individually indicate the color or other characteristic of the frame associated with the line of index mark. This information is received by a controller to control various printer functions.

    Abstract: A transmitter in a process control loop includes a sensor for sensing a process variable. An analog-to-digital converter coupled to the sensor provides a digitized process variable at various sample times. An interface couples the transmitter to the control loop and is used for communicating information and receiving power over the control loop. The transmitter includes a clock and a memory. A microprocessor coupled to the clock and the memory stores digitized process variables and clock information in the memory. The storage is such that the sample time of a stored digitized process variable can be determined.
