Abstract: Micro-Tracking Device (M-TDnm) is a micro-scale technology to assist in asset automated supply chain & logistics asset management employing OFiD (Optical Frequency Identification) and Raman scattering (a cumulative process having net effects of scattering photons and changing their frequency). This manipulation of frequency provides a ‘carrier wave’ for M-TDnm interrogation via Raman spectroscopy. The component parts of the M-TDnm (including silicone substrate, conduction band, and membrane) provide for an ‘E-beam resist’ function. The E-beam resist layer is coded with an arrangement of electrons, serving as a unique identifier. M-TDnm is subject to interrogation via Raman spectroscopy, the Raman spectrum reading is interpreted via an optical frequency identification (OFiD) method. Likewise alternate versions and variations can include energy harvesting mechanisms via polarity and conduction choice of the arrangement of electrons, and nanowire antenna.

Abstract: A solution for matching RADIUS request packets with corresponding RADIUS response packets when the number of simultaneous outstanding requests is greater than 256 involves using a sixteen-octet authenticator field in each packet. For each response packet that arrives, the identifier of the packet is compared in turn with the identifier of each outstanding request packet. If the identifiers match, the authenticators are then compared. If the results of the comparison indicate a match, the packet is accepted and no further processing of the outstanding requests is required. Otherwise, a search of the outstanding request packets is continued. This solution allows for more than 256 simultaneous outstanding RADIUS requests and only encounters a mismatch or ambiguous match with a probability of one in 3.4×1038 packets.
