Abstract: Scintillating glass ceramics are disclosed. The scintillating glass ceramics may be used as an x-ray conversion layer (screen) for a flat panel imager (FPD) and as part of an imaging system. The FPD may have a single screen or a dual screen. The scintillating glass ceramics may be used for either a front screen or a back screen. The scintillating glass ceramics may be used for high energy x-ray applications including for energies of about 0.3 to about 20 MeV. A build-up layer may be attached to the scintillating glass ceramics for high energy applications. The scintillating glass ceramics may include a glass matrix hosting luminescent centers and light scattering centers. The materials used for the luminescent centers and light scattering centers may be the same or different. The scintillating glass ceramics may be coated onto a glass substrate.

Abstract: The baton stand is a training device that is configured for use with a baton that is used in the relay race events of a track and field competition. The baton stand is a container within which a baton can be placed or removed as a runner passes by the baton stand. The baton stand is adjustable such that the baton stand will simulate the angle and height the baton should be in during the acceptance or hand off of the baton. To use the baton stand, a runner runs past the baton stand and, depending on the objective of the training exercise, will place the baton into or remove the baton from the baton stand. The baton stand comprises a telescopic stanchion, a stand, a basket, and a locking hinge. The stand attaches to the telescopic stanchion. The locking hinge attaches the basket to the telescopic stanchion.

Abstract: Analyte sensing devices suitable for measuring pH or other analytes are provided in a variety of form factors, including a hand-held device.

Abstract: Internally calibrated pH and other analyte sensors based on redox agents provide more accurate results when the redox active reference agent is in a constant chemical environment, yet separated from the solution being analyzed in such a way as to maintain electrical contact with the sample. Room temperature ionic liquids (RTIL) can be used to achieve these results when used as a salt bridge between the reference material and the sample being analyzed. The RTIL provides the constant chemical environment and ionic strength for the redox active material (RAM) and provides an electrolytic layer that limits or eliminates direct chemical interaction with the sample. A broad range of RAMs can be employed in a variety of configurations in such “Analyte Insensitive Electrode” devices.
