The present invention relates to a method for monitoring the effect of in vivo administration of Cathepsin S inhibitors by measuring accumulation of an intermediate degradation product of invariant chain, in particular the p10 Ii fragment, in blood of dosed subjects. The process includes using an image file and an insertion algorithm to generate an image feature vector Vsi, storing the image feature vector Vsi in the microchip, using the printed image obtained by a scanning device to generate an image feature vector Vsi, and using a read-back algorithm to match the image feature vector Vsi and the image feature vector Vsi. The remote computer receives the electronic mail message and extracts the state of the embedded device from the message. Furthermore, an ordered list-specific seed value may be prepended to each item’s path value to ensure clustering of ordered list items when two or more ordered lists are merged. Based on the first computer receiving the message indicating that the range of serial numbers identified by the file correlates to the range of serial numbers identified by the order, the first computer ships the devices. The electrical wires incorporate a quick-disconnect coupling and a switchdimmer control to control the speed of the fan.
