Accuflate measures the temperature and pressure of a tire and by processing this information through an Allen Bradley Micrologix and comparing this information to the ambient air temperature and the recommended inflation pressure allows the operator to inflate the tire to a SET-POINT PRESSURE so that when the tire has cooled it will be at the recommended operating level. Using a shim, executing at each node, to monitor each of the processes, the parallel process is debugged such that neither the process or the particular message passing system implemented on the cluster, needs to know of the existence or details regarding the debugger. The adapter has an external diameter which is substantially equal to the internal lumen of the catheter and further includes a smaller internal lumen which is substantially equal in diameter to the guidewire and is therefore capable of accommodating the smaller diameter guidewire therethrough. Thereafter, an image of a light source is formed on a pupillary surface of a projection optical system from light diffracted by the photomask.
