A method is presented for taking an unknown field of transponders and converting them to a slotted Aloha architecture and increasing the throughput allowed by the slotted Aloha architecture by using several different techniques including shortening the time of empty and collided timeslots, implementing a unique random number generator that creates random numbers that are uniquely based on an individual tags location, and on an ability to estimate the total number of transponders and control the offered rate such that throughput is always maximum. While these techniques work well together and produce the most benefit when used together, they are independent techniques and any one may be used alone without the others. Thus a system might use the estimated total number of transponders technique and the timeslot shortening technique, but use a standard random number generator rather one based on transponder location with only a small decrease in overall performance.

A system comprising an RFID Reader and an array of RFID Tags, where the tags have the ability to measure physical signal properties such as FM deviation and Received Signal Strength as examples and use these measurements to create a means to refrain from responding to the Reader, unless the measured values fall inside a range determined by a built in algorithm or decision tree or by the Reader and transmitted to the array of Tags in an outbound message. The system may also use non-physical parameters, including tokens sent by the Interrogator/Reader to the Tag field. Moreover, physical parameters may be divided into maskable and unmaskable parameters. Signal frequency is not maskable by the environment, for example, but signal amplitude and phase are maskable by the environment during propagation. Additionally, the number, the nature and the range of each Multidimensional Variable are set by the Interrogator at the start of a session. In this way, foreknowledge or good estimates of the tag population will lead to higher efficiency operation

A method and system for reading RFID tags in a high-density environment using a directional scanning antenna system is provided. The directional scanning antenna system consists of transmit and receive antennas having highly directional antenna patterns which work together to read and locate the tags. In operation both types of antennas are stepped in a circular fashion with respect to each other wherein the transmit antenna's antenna pattern pauses during rotation while the receive antenna pattern sweeps across the radiating antenna's path produced by the transmit antenna such that the antenna patterns produced from each isolate and determine the location of the tags.

A quadrifilar helix antenna for use in satellite communications comprises four conductive elements arranged to define two separate helically twisted loops, one slightly differing in electrical length than the other, to define a cylinder of constant radius supported by itself or by a cylindrical non-conductive substrate. The two separate helically twisted loops are connected to each other in such a way as to constitute the impedance matching, electrical phasing, coupling and power distribution for the antenna. In place of a conventional balun, the antenna is fed at a tap point on one of the conductive elements determined by an impedance matching network which connects the antenna to a transmission line. The matching network can be built with distributed or lumped electrical elements and can be incorporated into the design of the antenna.

A system and method is provided which allows for instant recognition of contents of a closed container by providing descriptive information in the form of a picture, and/or an audio description, and/or text of the contents of the closed container taken at the time of packing the container. The system keeps track of the contents of an individual container by storing information describing the contents of the container that is then related to a unique identification number stored in a radio frequency identification tag affixed to the container. This information is then stored in a digital database for later reference.
