An apparatus for determining the location of a vehicle occupant in a vehicle interior includes a light source for projecting at least one structured light beam onto an area of interest to form a light pattern on the area of interest. Each bank sequencer controls the dispatch of load and store requests to a central controller such that each request sent to the central controller can be served by the associated memory bank at the time that the central controller receives the request. The probability of improvement for input parameter settings can be determined from an analysis of the compilation results of sample designs, from attributes andor constraints of the user design, andor from a correlation between the results of optimization algorithms applied to the user design. The invention further relates to a system for performing this method. The signed authorization number is signed by the third party but unknown to the third party.
