Abstract: A location awareness system including a communication network, and a network operating element coupled to the communication network. At least one anchor network gateway is coupled to the communication network, the at least one anchor network gateway configured to generate a wireless anchor network. A plurality of anchors are configured to couple to one of the at least one anchor network gateway via its respective wireless anchor network. A plurality of tags is each configured to communicate with at least one anchor to provide ranging information for determination of a position of the tag within an area covered by the system.

Abstract: A wireless field device for use in an industrial process includes input/output terminals to couple to a process interface element and a discrete input/output channel configured to receive a discrete input signal from the process interface element through the input/output terminals when configured as a discrete input channel, the discrete input/output channel further configured to provide a discrete output to the process interface element through the input/output terminals when configured as discrete output channel. Wireless communication circuitry transmits and receives information. A controller transmits information through the communication circuitry based upon a sensed process variable, provides a discrete output signal when the discrete input/output channel is configured as a discrete output channel and receives a discrete input signal when configured as a discrete input channel. An external power supply input is couples to an external power supply and a battery power supply input couples a battery.

Abstract: A device for the purification of exhaust air produced during the processing of wood materials comprises a first circuit (A) having a scrubber (2), a mist eliminator (4) and a regeneration container (7). In order to strip the washing liquid from organic substances, a second circuit (B) is provided and serves to remove a sub-stream of the washing liquid from the first circuit (A) and supply it to a desorber (12). The washing liquid purified in this way is recirculated to the first circuit (A).

Abstract: A fluorescence flow cell having a capillary through which a sample fluid is moved, an optical source that directs an exposing beam of light through the sample fluid, a collector that collects fluorescent light from the exposed region of the sample and directs such collected light to a detector. A beam blocker prevents light that is scattered by the capillary walls from reaching the detector, thereby improving the signal-to-noise ratio of the system. The beam blocker also has a pair of legs that prevent the sample fluid from being exposed by either the exposing light or the collected light outside of the exposing region. The structure of the components enables the various components to be quickly and accurately assembled and enables easy replacement of the capillary.

Abstract: A method for the determination of the drug or other analyte content and concentration in bodily fluids that are directly injected in a micellar chromatographic column. Various embodiments of kits are also disclosed.
