A mobile device for handling objects includes a radio frequency identifier reader for receiving radiation emitted by object-specific radio frequency identifiers attached to the objects and radiation emitted by fixed radio frequency identifiers. The mobile device includes a processing system that computes a speed estimate for the mobile device based on a distance between two fixed radio frequency identifiers and a time-difference between receptions of radiation from these fixed radio frequency identifiers. The processing system determines, based on radiation received from each object-specific radio frequency identifier, a movement indicator indicative of movement of the mobile device with respect to the corresponding object. When the speed estimate exceeds a threshold, the processing system classifies objects which are moving in accordance with the movement indicator to be objects non-belonging to a load of the mobile device. The mobile device can be for example a forklift.

A multizone equipment tracking solution includes radio frequency identification (RFID) tags affixed to items of inventoried equipment; a plurality of RFID readers deployed in a plurality of different zones, including a transit zone and a storage zone, wherein an RFID reader in a transit zone comprises a mobile reader and a wireless signal strength measurement component; and a monitoring node. The RFID readers read tag codes from items that are in the different zones, and report the information to the monitoring node, permitting a real-time, end-to-end view of inventoried equipment across different zones. The RFID reader in the transit zone also measures a wireless signal strength (e.g., cellular) along a transit route and reports the measurements, thereby reducing a need for dedicated monitoring efforts by the wireless network operator. Reported data, may be advantageously mined to provide value for inventory management, while also providing cost savings for wireless network management.

A two-dimensional code is attached to a location of a reagent storage unit which is visually recognizable from the outside, and a coordinate position of the two-dimensional code in a coordinate system of the two-dimensional code and coordinate information of an installation position of a reagent bottle are held. After that, an image of the two-dimensional code is captured by a portable terminal so that a coordinate system of an image capture unit of the portable terminal is converted into the coordinate system of the two-dimensional code using AR technology. The coordinate information of the installation position of the reagent bottle in the coordinate system of the two-dimensional code is regarded as positional coordinates in the captured image on the basis of the conversion, thereby ascertaining the position of the reagent bottle on the captured image and displaying the ascertained position on a display unit.

A radio frequency communication device includes a conductive loop electrically connected to an integrated circuit arrangement and a pair of opposing elongated conductors extending away from the conductive loop.

Embodiments of the present disclosure generally relate to systems and methods for detecting misplaced items in an establishment. In one implementation, the system may include at least one processor configured to receive from at least one reader in the establishment, identification signals of tags read by the reader; determine current locations of the tags; and record the current locations of the tags. The processor may also be configured to access a designated location in the establishment for each of the tags; and determine, by comparing the current locations with the designated locations, a particular tag with a current location that differs from the designated location of the particular tag. The processor may also be configured to generate a notification signal when the current location of the particular tag does not match the designated location of the particular tag.

One embodiment of the present invention relates to a method for a reader to transmit and receive a signal to and from a tag, the method comprising: a step in which a first reader transmits a first signal to a tag; and a step in which the first reader receives the first signal reflected on the tag. The timing for the first reader to transmit the first signal is determined by using an offset value based on an ID related to the first reader.

A disclosed terminal device includes: an article display unit displaying article information relevant to articles in a list on a display, on the basis of identification information of the articles that is read out from RFID tags provided in storage bodies storing the articles; and a quantity setting screen display unit displaying a screen for setting an inventory quantity of the article selected from the article information displayed on the display, on the display.

A wireless tag for sensor control is connected to a sensor and configured to control execution of measurements using the sensor. The wireless tag for sensor control includes: an antenna for receiving a radio wave or a magnetic field transmitted from an external wireless device; a power generation unit configured to generate electric power based on the radio wave or the magnetic field received by the antenna; and a control unit configured to control the sensor using generated power, which is the electric power supplied from the power generation unit, wherein the control unit includes: a power supply control unit configured to use a portion of the generated power to execute power supply to the sensor; an acquisition unit configured to receive a detection result from the sensor operated by the execution of the power supply; and a transmission processing unit configured to transmit communication information including the detection result to the outside.

The present invention discloses a method for predicting a tag arrival rate of a mobile Radio Frequency Identification (RFID) system. The method includes: first, establishing a dynamic tag arrival model for a mobile RFID system based on modeling data and a grey model GM(1, 1); improving a weight of an initial value of a differential equation of the grey model through weighting; and predicating a tag arrival rate based on a sliding window mechanism. A weighted grey model predication algorithm based on the sliding window mechanism can be obtained, to predicate a tag arrival rate of a mobile RFID system. The method for predicting the tag arrival rate of the mobile RFID system of the present invention can reduce a prediction error rate of the system, maintain a modeling length of 4 for the system through the sliding window mechanism, and update modeling data online.

Methods, apparatus, systems, and computer-readable media are provided for generating a spatio-temporal object inventory based on object observations from mobile robots and determining, based on the spatio-temporal object inventory, monitoring parameters for the mobile robots for one or more future time periods. Some implementations relate to using the spatio-temporal object inventory to determine a quantity of movements of objects that occur in one or more areas of the environment when one or more particular criteria are satisfied—and using that determination to determine monitoring parameters that can be utilized to provide commands to one or more of the mobile robots that influence one or more aspects of movements of the mobile robots at future time periods when the one or more particular criteria are also satisfied.
