Abstract:
The invention relates to a method for examining at least one object during which properties of the object are detected at different times within a spatial frequency space formed by spatial frequencies. According to the invention, the method is carried out in such a manner that temporally consecutive recordings ensue in overlapping regions of the spatial frequency space and additionally in regions of the spatial frequency space that differ from one another.
Abstract:
An automatically operable dynamic purge system that is incorporated into a heat recovery wheel that comprises a number of radial seals that direct a controlled area of supply air into the exhaust air stream passing through the heat recovery wheel. Two possible configurations include a single purge and a double purge. For the single purge, one seal is fixed in location on one face of the wheel and a second seal is dynamic and is on the opposite face. For the double purge, two seals are fixed in location on one face of the wheel and a third seal is dynamic and is on the opposite face. In each case the dynamic seal is secured by an automatically operable wiper blade. This wiper blade is attached near the center of the wheel such that it rotates, in turn, allowing the seal to rotate while remaining approximately radial to the wheel.

This is done such that temporally consecutive recordings are made in overlapping regions of the spatial frequency space and also in regions of the spatial frequency space that differ from one another.
