Abstract: A method for sharing digital content includes determining whether a first computing device is physically located within a defined geographical area, if the first computing device is physically located within the defined geographical area, providing access of shareable digital content to the first computing device, instantiating a tethering object associated with the shareable digital content, the tethering object including at least a first endpoint at the first computing device and a second endpoint at a second computing device remote from the first computing device, and providing access of at least a portion of the shareable digital content, via the tethering object, to the second endpoint at the second computing device remote from the first computing device. Other example methods and computer systems for implementing content sharing methods are also disclosed.

Abstract: A thermally reflective membrane apparatus comprises a housing structure, and a thermally reflective membrane contained within the housing structure. The thermally reflective membrane comprises a semipermeable structure, and a porous, thermally reflective structure physically contacting the semipermeable structure. The porous, thermally reflective structure comprises discrete thermally reflective particles, and a binder material coupling the discrete thermally reflective particles to one another and the semipermeable structure. A fluid treatment system and method of treating a fluid are also described.

Abstract: An air curtaining apparatus is disclosed that forms a U-shaped air curtain around a steam and heat-emitting piece of machinery, such as a garment form finisher, to protect an operator from heat and moisture emitted during operation of the form finisher while permitting manipulation of a workpiece disposed thereon.

Abstract: Signals at selected points on a test device place indicia on a record indicating, for each selected point, a selected logical active level and an initial polarity level. At preselected time intervals, levels, level changes and the number of transitions per change appear on the record as human-readable symbols. Each selected points signals are translated into digital representations which are stored for comparison with subsequent digital representations from the point. Counters record the number of changes thus detected and provide to the record appropriate symbols depicting the pre-change value, the number of changes and the post change value.
