Chipless RFID is a potential alternative to chip based RFID for low cost applications. Enhancing the bit capacity and adding the programmable feature in a chipless tag has been approached via multiple techniques. We have taken advantage of the symmetry properties of split ring resonator to construct a mechanically reprogrammable chipless tag. A slotted signal line CPW (SSLCPW) is designed to produce high-Q resonances. Two port simulation results are presented and the tag is able to utilize 1 GHz bandwidth to generate atleast 225 IDs. A practical end to end implementation of the tag with two cross polarized UWB antennas is also proposed and results are presented for selected tag IDs.

A novel localization method is proposed and demonstrated which exploits the phase profile combined with the location of the moving robot to locate target tags using only a single straight-line interrogator antenna trajectory. A system that integrates a mobile robot with an integrated RFID reader and antenna is used to obtain phase measurements of target tags when the robot is moving along its trajectory. The cross-range location of the target is obtained from the stationary point of the fitted phase curve. The down range distance is estimated by finding the integer number of wavelengths which fits the cross-range location and curve shape. The proposed method could reduce the localization error to around 12 cm which is similar to the SAR method using a straight-line trajectory, but with much lower computational complexity.

As a general introduction to Colossians, readers always face the questions of who wrote the letter, when, who is the intended audience, what is the purpose for writing, what are the themes, how does this writing compare with other writings, and what is the letter's authenticity? As to the latter question of authenticity, its genuineness has been, as Daniel Wallace points out, "assailed on critical grounds" by T. Mayerhoff, F.C. Baur and the Tübingen school (See Wallace below). General consensus seems to suggest Colossians was written by Paul, or should have been since it so closely structures a Paulinian theology, in the end 50's to early 60's during Paul's first Roman imprisonment.The purpose for the letter seems to have been to combat new and popular teaching that would subvert the pure gospel. New Advent says Colossians was written to combat a number of worldly teachings:
