Abstract: An electrode assembly for an electromagnetic flow meter (1; FIG. 1) is disclosed. The electrode assembly comprises a housing, which may be a flow tube (2; FIG. 1) of the electromagnetic flow meter, having a passage (123) between first and second ends (1241, 1242), an electrode (125) comprising a plug of porous material, for example formed of porous graphite, at least partially disposed within the passage proximate the first end, and an electrically-conductive polymer connector (125) at least partially disposed within the passage and in direct contact with the electrode.

Abstract: The present invention is directed to systems and methods which utilize a cavity ring-down spectroscopy (CRDS) technique implemented for the measurements of vapor transmission rate. In one embodiment, the vapor content to be measured is contained within an optical cavity. Light is then injected into the cavity up to a threshold level and the decay time of the injected light is measured. When the wavelength of the injected light is resonant with an absorption feature of the vapor the decay time increases linearly as a function of vapor content. In this manner, vapor content causes a longer decay time and thus the amount of vapor passing through the film (film permeation rate) can be determined in real-time.

Abstract: Capturing interconnectivity data for one or more multi-pin devices in the design of emulator circuit boards is automated using a translator that extracts relevant information, from a text-based input/output (I/O) definition file. The I/O definition file contains textual descriptions of I/O connectivity information for the various devices created by partitioning the design for application on the emulator circuit board, undefined connector interface entries, and design-specific information. The translator parses through the I/O definition file extracting the I/O connectivity and design-specific information, and retrieves connector interface definitions for the undefined connector interface entries using vendor data.

Abstract: A method and apparatus for transmitting utility meter data from an underground meter pit. The device includes a radiating antenna that is positioned entirely above the top surface of the pit lid. The radiating antenna conductively contacts a portion of the transmitter supported on the pit lid by the antenna housing. The transmitter housing includes an isolation sleeve that physically contacts a portion of the radiating antenna to enhance the signal transfer from the transmitter to the radiating antenna.
