Abstract: A tamper detection monitoring apparatus and body. The monitoring apparatus includes a housing (14) having a first (15) and second (16) side, a light detector and a first connector (15a) on the first side, and a light emitter and a second connector (16a) on the second side. The monitoring apparatus further includes a strap (12) having a first end for coupling to the first connector and a second end for coupling to the second connector, wherein the strap contains an optical fiber. The monitoring apparatus further includes a first focusing lens disposed between the light detector and the first end of the strap and a processor configured to measure the variation in light received by the light detector.

Abstract: Retroreflective images are formed on garments and other substrates with a transfer sheet material that comprises a support sheet, a dense continuous monolayer of transparent microspheres partially embedded in the support sheet, and a thick transfer layer printed over a limited portion of the continuous layer of microspheres in an imagewise pattern. In use the transfer sheet material is laid against a substrate, the transfer layer adhered to the substrate, and the support sheet stripped away. The transfer layer remains in place and pulls the microspheres from the support sheet, leaving a sharply defined design that is retroreflective over the full area of the design.
