Techniques are provided for individual data objects in an enterprise computing system, where the individual data objects represent unique assets of a family of assets. The cross braces form a honeycomb structure, in which the transmitting and receiving elements of the light grid are installed. The method further includes setting a starting point and search directions, determining a point before a first boundary point as an origin of the region and searching the next boundary points if the first boundary point has been searched. A time interval until the identified feature is next repeated in the input data stream is then measured. Spectral similarity may also be achieved by using alternative components with spectral characteristics similar to the components contained in the test sample of interest.
