Automating Evidence Collection at the Crime Scene Using RFID Technology for CBRN Events

Abstract

In forensic management, radio frequency identification (RFID) technology has a potential to improve the chain of evidence, automate the control of exhibits moving out from a hot zone, help locate exhibits in the property control unit (PCU), and reduce human errors and the amount of paperwork due to duplicate data entry. The goal of this paper is to experimentally investigate the efficacy of RFID technology for evidence gathering in a hot zone and for controlling entry to and exit from the hot zone of first responders and exhibits. We performed three evaluation exercises where forensic technicians had a chance to experiment and evaluate the technology as it applied to their duties. Long-range passive RFID technology in the ultra high frequency (UHF) range was used. Based on our observations and the interviews with the forensic technicians who participated in the exercises, we conclude that the technology is suitable for tagging the exhibits and that it has a good potential for controlling the exit point of exhibits and first responders.

Ergonomics Systems Mapping for Professional Responder Inter-operability in Chemical, Biological, Radiological and Nuclear Events

“…This model allowed for response phases and events to be established but also had no detailed information about tasks that should occur, lines of communication needing to be established and where technologies might fit into the system. Having access to technologies, such as those which can quickly detect and identify substances or track patients and evidence in this chaotic environment can aid in situational awareness, thus reducing the psychological distress placed on emergency responders [15][16][17][18].…”

Composite of Flake-Shape Sendust Particles and its Application on Patch Antenna

“…In recent years various wireless communication systems have been widely used for their convenience, but it also causes the public exposure to electromagnetic (EM) field and leads to the associated health issue at the same time [1][2][3]. Magnetic materials which maintain significant electromagnetic wave (EMW) absorption performance have been essential for reducing EM field at radio frequencies in this situation.…”
