Systems, asset tag devices, and methods are described herein to provide asset, or object, tracking using a plurality of beacons. The asset tag devices may be affixed, or coupled to, the asset, or object, and may receive beacon advertising packets from the beacons, and then transmit, or broadcast, tag advertising packets including information from the received beacon advertising packets, which may be used to determine an approximate location of the asset tag device, and in turn, the asset or object.

A gaming table contains a number of antennas that are de-tuned from the resonant frequency of a single RFID tag. This increases the power required to read the single tag but matches the resonant frequency for reading a stack of RFID tags. The gaming table may further include a network analyzer and a set of capacitors that are dynamically switched among the antennas according to measuring the reflection coefficient of the antennas.

It is described an RF communication device comprising: i) an RF antenna functionality; ii) at least one antenna pad connected to the RF antenna functionality; iii) a further functionality which is not an RF antenna functionality; and iv) at least one non-antenna pad electrically connected to the further functionality.

The antenna pad and the non-antenna pad are arranged to be short-circuited with each other, and the non-antenna pad is electrically connected via a connection line to the further functionality within the RF communication device.

Further, a method of manufacturing an RF communication device is described.

A near field communication device and a method of determining the position of a tag are provided. The near field communication device includes a first coil, a second coil, and a control circuit. One end of the first coil is coupled to a first grounding end. One end of the second coil is coupled to a second grounding end. The control circuit includes a first current pin and a second current pin. The first current pin is coupled to the other end of the first coil. The second current pin is coupled to the other end of the second coil. The control circuit transmits a first current signal to the first coil by the first current pin, and transmits a second current signal to the second coil by the second current pin, the control circuit analyzes the change of the first current signal and the change of the second current signal to determine whether the position of a tag is close to the first coil or close to the second coil.

The present disclosure relates to a reader, such as a reader for a physical access control system. The reader can include first and second antennas, each designed or configured for receiving ultra-wide band (UWB) signals. The reader can also include a mounting plane configured for mounting the reader to a surface. An axis aligning the first and second antennas can be arranged substantially perpendicular relative the mounting plane. A material can be provided between the first and second antennas The material can have a thickness that defines a distance between the first and second antennas of less than a half wavelength of the UWB signal through air (λ.sub.A/2), the material configured to slow down electromagnetic waves passing therethrough such that the thickness of the material provides an effective separation distance of the first and second antennas of at least a half wavelength of the UWB signal through air (λ.sub.A/2).

A wireless tag reading device of an embodiment that is for reading tag information of a wireless tag attached to an article housed in a housing portion, including: a bottom surface portion; and a plurality of side surface portions erected upward from an end of the bottom surface portion, the housing portion being surrounded by the bottom surface portion and the side surface portions, in which the wireless tag reading device includes: inside the side surface portions, an antenna that radiates a radio wave into the housing portion; a radio wave reflecting unit that is provided outside the antenna and that reflects the radio wave radiated from the antenna toward the housing portion; and a radio wave absorbing unit that is provided at an upper portion of the radio wave reflecting unit and that absorbs the radio wave radiated from the antenna.

An improved automated inventory system is herein disclosed. The improved automated system (AIS) can comprise an enclosure for storing one or more items, one or more RFID readers, and a control system. Each of the items are tagged with an RFID (radio frequency identification) tag. The enclosure can comprise a plurality of of interior surfaces that defines an interior space within said enclosure. The enclosure can also comprise one or more access points within the interior surfaces that allow access to the items within the enclosure. Each of the RFID readers can be capable of reading the RFID tag. The control system can be in communication with the one or more RFID readers.

An article registration apparatus (100) includes: a reading unit (102) that reads article identification information from an IC tag associated with an article by using at least one of a plurality of antennas; a control unit (106) that controls the reading unit (102); a judgement unit (104) that judges whether a reading result of the reading unit (102) satisfies a criterion; and a determination unit (108) that determines the article identification information read by the reading unit (102), wherein the control unit (106) causes the reading unit (102) to read the article identification information by using a first antenna, the judgement unit (104) judges whether a reading result of the first antenna satisfies the criterion, the control unit (106) causes the reading unit (102) to read the article identification information by using a second antenna different from the first antenna when the reading result of the first antenna satisfies the criterion, and the determination unit (108) determines the article identification information to be output, by using the article identification information read by using the first antenna and the second antenna.

The present invention relates to technological improvements, use of these improvements and data analysis to provide for improved surgical procedure efficiency, efficacy, and safety. Specifically, improved radio frequency identification (RFID) enabled technology is utilized to discover and rectify significant inefficiencies, safety concerns and risks involved with surgical procedures through improved surgical implement tracking, both temporally and spatially, and data analytics for gathering, tracking and analyzing of instrument use singly and in combination.

Disclosed is a system and method for wirelessly monitoring 5 process conditions within a reactor vessel. A plurality of sensor-enabled radio frequency identification (RFID) tags are disposed at unspecified or random locations throughout a catalyst bed of a vessel and are used to measure various conditions within the vessel. The sensor-enabled RFID tags are encoded with individual identification codes and are wirelessly linked to multiple 10 transceivers. The use of multiple transceivers allows for the application of triangulation methods to identify the location of each of the sensor-enabled RFID tags in three dimensional space and for the interrogation of each sensor-enabled RFID tag to receive responsive transponder signals that carry information representative of the sensed condition within the reactor.
