Radio-frequency identification

This paper aims to study the development of radio frequency identification RFID technology through an analysis of patents filed with and issued by the US Patent and Trademark Office. A close analysis of these clusters reveals the patent development strategies of two competing factions of RFID technology developers. This paper provides an analysis of the patents along with insights into the contents of the patents held by these two groups. The findings support a strong link between intellectual property and competitive advantage — specifically Intermec Technologies, which have not joined the RFID Patent Pool. The patent search results show that Intermec Technologies hold basic RFID patents in the early stages of technology development, which has placed the company in a dominant position. The features of each cluster clearly depict the niches and specialties of companies and provide a historical framework of RFID technology development. The RFID patent analysis shows that if a company holds crucial patents in the early stages of a developing technology which relate to the fundamental key aspects of the technology, then the company will be more likely to maintain a leading and dominant position in that industry segment i.

This paper presents a new approach for RFID tag attribute matching problem. Furthermore, we do not need expensive homomorphic encryption or multiparty computation and we extend attribute matching to multiple attributes per tag; a feature that broadens the range of possible applications of the protocol. We achieve this increased flexibility and decreased complexity by moving some relatively cheap cryptographic computations to the tags.

Specifically, one of the protocols presented in this paper only needs a lightweight hash function implemented on the tags. Two other protocols additionally need asymmetric encryption, which is feasible on more powerful tags that support elliptic-curve scalar multiplication. His constructive suggestions and willingness to spend his time so generously is very much appreciated. We would also like to thank Ari Juels for very fruitful discussions. Skip to main content.

Passive tags may have advantages such as low cost, light weight, small form factor, and long operational life due to the absence of a battery, but have limited range since only a few microwatts may typically be harvested. Active RFID tags may be more expensive, heavier, larger, and their operating life limited by the battery, but their range may be much greater due to the power available from the battery.

Some applications are more suited to passive tags, while other applications are more suited to active tags. However, some applications could benefit from both, but placing both types of RFID tag on the same object may greatly increase the cost. Some embodiments of the invention may be understood by referring to the following description and accompanying drawings that are used to illustrate embodiments of the invention. In the drawings:.

New Hampshire. Sixteen ski areas are advertising RFID ticket systems this season. As of the season, 16 New England ski areas in 3 states are expected to use the technology. Boyne Resorts is the latest owner to deploy the technology, as it has installed gates at Loon for the upcoming season. While the technology has origins dating back to the mid twentieth century, widespread commercial usage has taken place in the past few decades, as chips have become smaller and more affordable for identification cards and transit tolling.

Though expensive to deploy, RFID in theory can decrease labor costs, as well as reduce theft of service. With RFID passes, returning skiers can pay for their passes online, thus reducing demand on ticket windows. In addition, with seamless lift gates, employees no longer need to manually scan tickets. RFID technology also allows for easy implementation of multi-resort passes, the most popular being Epic and Ikon.

Though theft of service through unauthorized transfers is still an issue, some installations incorporate photo and biometric verification.

US8269606B2 – Methods and systems for RFID tag read verification – Google Patents

Radio-frequency identification RFID uses electromagnetic fields to automatically identify and track tags attached to objects. An RFID tag consists of a tiny radio transponder; a radio receiver and transmitter. When triggered by an electromagnetic interrogation pulse from a nearby RFID reader device, the tag transmits digital data, usually an identifying inventory number, back to the reader. This number can be used to inventory goods. There are two types.

RFID tags and readers have been utilized in a multitude of applications. As the tags are read, a record is kept of each read. For the data to be retained, it has to be output to an external system prior to the system being powered down or turned off. A problem with the above described process is that, as the number of unique tags read grows beyond a dozen or two, it is not possible to very quickly identify which tags were read, and which tags were not read, to verify the accuracy of RFID tagging and reading processes.

More specifically, known RFID tag and reader systems are not believed to have a capability to compare imported read data with known RFID tag identifiers, locations, and control data e. To date, in order to verify which RFID tags incorporated within a system were read, and not read, copious hand-written notes have been utilized.

The notes, along with the text string output of the records stored in the RFID tag reader, are then manually deciphered to determine if the desired reads took place.

RFID technology has attracted an enormous interest worldwide, since the earliest pioneering ideas dating back to A number of applications can now be.

The antennas are embedded into the concrete spillway ogee. The wireless tracking system includes several engineering feats to capture tag transmissions. This involves enlarging the RF field in which the tags can be read, as well as reducing the volume of data being transmitted by tags, thereby ensuring each transmission is received in the time period during which the salmon are within read range.

The tracking efforts are intended to help researchers understand salmon populations in the Columbia River and related waterways, whose numbers have been dwindling. Salmon loss results from a variety of factors that could include the dams, habitat loss, heavy fishing and climate change. In recent years, BPA has been required to spill more water through its dam annually, in order to get more salmon over the dam and into the sea, which means the fish themselves are moving faster within a larger volume of water.

With the larger volume of water moving through the spillway, however, a smaller portion of fish do not use the bypass system, leading to a increase in the proportion of fish passing via the spillway. Your email address will not be published. Your Website.

The reader then converts the radio waves to a more usable form of data. Drugs collected from the tags is drugs transferred through a communications interface to a host computer system, where the specialty can be stored in a database and analyzed at a later time. As stated above, an RFID tag consists of an integrated circuit and an antenna. Dating tag is also composed of a protective material that holds the pieces together and shields them from various environmental conditions.

NOAA has been using RFID to track salmon dating back to the s, when KHz tags were inserted in fish. The tracking efforts are.

Muscat, the capital of Oman, is a beautiful, ancient city and a major port on the Gulf of Oman with a history dating back to the 6 th millennium BCE. Muscat was built on rocky areas surrounded by the Al Hajar Mountains. Unfortunately, this topography has made it difficult to rectify a problem shared by other old-world cities that were built without specific corridors for utilities. Muscat, Oman. In Oman, the majority of cities use septic and holding tanks to collect sewage water, and, as a result, distinctive yellow tankers travel around suctioning wastewater into their tanks and transporting it to sewage treatment plants.

The Haya Water Company, under a concession agreement with the government, provides this service to over , people, connecting all areas of Muscat, and surrounding governorates, with sewage treatment in a nearby waste water treatment facility. Haya Water Trucks. Haya Water’s wastewater treatment facility charges tanker trucks a fee for entry. This is a high-volume facility, and initially manual collection of fees was creating long lineups of vehicles at the gate. Delays were a service issue for users of the facility, and without an audit system there was potential for losses to the operator.

With a large number of returning vehicles they needed a fast, automated collection system that would optimize throughput at the entrance to the plant.
