Abstract: The invention relates to a method in which a starting material for injection-molding, having a viscosity of between 0.50 and 0.7 dL/g, is produced with the aid of a chain breaker from a recycled post-consumer PET having a viscosity of between 0.72 and 0.86 dL/g according to ASTM D4603 and a copolymer fraction of at most approximately 3%. In the method, the comminuted and dried PET material is melted and decontaminated to such a degree that it is suitable for applications in the food sector and the consumer goods sector. A chain breaker is added to the rPET material in the melt of the recycling extruder and/or preferably the melt of the injection unit in order to lower the viscosity and to enrich the PET with copolymers.

Abstract: Radio Frequency Identification (RFID) tags have the capability of sending large strings of numbers unique to that tag using radio waves. This application looks to use RFID tags to assist navigation and location tracking within a building. The RFID tags, which have a radiation range of 3 feet, will be placed on the floor of the building. Each tag will represent an area on the floor with a number which can be accessed by passing an RFID reader over the area of the tag. A computer program in the RFID reader will be able to translate the number using a database into voice, print the information on the screen, search the database for items, or give directions to certain items. Also a program will be created so store managers can update the database and use a map of the building to easily write descriptions for each RFID tag area.
