Abstract: Certain embodiments of the invention relate to an apparatus for fluid leak detection. The apparatus includes a fluid supply conduit for supplying fluid to an external structure and a substantially parallel fluid return conduit for carrying fluid away from the external structure. The apparatus further includes: an oscillator for causing a separation of the fluid supply conduit and fluid return conduit to vary over time; sensors disposed relative to the conduits to measure the separation at respective opposed portions of the conduits; and a processor coupled to the oscillator and the sensors. The oscillator is responsive to the processor and receives respective separation measurement signals from the sensors. The processor is configured to determine whether there is a difference between a supply fluid mass flowing in the fluid supply conduit and a return fluid mass flowing in the fluid return conduit based on the separation measurement signals.

Abstract: Certain embodiments of the invention relate to an apparatus for fluid leak detection. The apparatus comprises a fluid supply conduit for supplying fluid to an external structure and a fluid return conduit for carrying fluid away form the external structure, wherein the fluid supply conduit and the fluid return conduit are disposed in parallel with each other. The apparatus further comprises: an oscillator for causing a separation of the fluid supply conduit and fluid return conduit to vary over time; first and second sensors disposed relative to the fluid supply conduit and fluid return conduit to measure the separation at respective first and second opposed portions of the fluid supply and return conduits; and a processor coupled to the oscillator and the first and second sensors. The oscillator is responsive to the processor and the processor receives respective first and second separation measurement signals from the first and second sensors.

Abstract: A tile panel system has a frame for supporting one or more tiles. The system includes a plurality of vertical support member. Attached to the support members are two piece blocks that clamp around the vertical supports. Horizontal rails then extend between oppositely positioned clamp. Tiles are then releasably secured to the horizontal rails via spring clips or other appropriate mechanisms.
