Title: Method of characterization of surface coating containing metallic flakes and device used therein
Inventor: RODRIGUES ALLAN BLASE JOSEPH
IPC: B05B1/00
Filed: 2004-06-10
Abstract: The method of present invention and the device used therein is directed for characterizing unknown metallic flakes present in an existing coating on a substrate such that a matching metallic paint composition can be formulated and applied over the substrate to produce a metallic coating having characteristics, such as flop, that match the existing coating. The method includes directing a beam of light at a preset intensity towards a target portion of a target coating; directing a reflection of the portion to a photosensitive surface to capture a target image of the target portion;  measuring characteristics of the unknown metallic flakes in the target image at said preset intensity; correlating the characteristics of the unknown metallic flakes in the target image to stored characteristics of known metallic flakes at that preset intensity to identify one or more the known metal flakes that match the characteristics of the unknown metallic flakes;  and displaying the identified one or more known metal flakes that match the characteristics of the unknown metallic flakes. Once the characteristics are known, a formulator can then formulate a metallic paint that can be applied over the surface of a substrate, such as a repaired autobody, to produce a metallic coating that matches the remainder of the autobody.

Abstract: A method of operating an ad hoc network comprising a plurality of devices (11-16). Each device includes communication means for communicating with other ones of the plurality of devices when they are in range. The method involves storing on each device one or more nodal policies (1-6) which specify rules for determining how a device should behave in response to various prevailing circumstances and controlling each device to operate in accordance with one or more of the stored nodal policies. Additionally, each device stores a fitness parameter and adjusts the value of the fitness parameter in dependence upon the level of activity of the device (in particular, activity which is consistent with its stored policies). Additionally, each device monitors the value of its stored fitness parameter and the activity of its communication means and transmits (46, 48, 49), to other ones of the devices which are in range (13, 15, 16) one ore more of its stored nodal policies (5) in the event that its fitness parameter exceeds a threshold of value and its communication means is not required for other purposes.
