Electronic badges are indirectly tracked by detecting, by a badge communicator on a select industrial vehicle of a fleet of industrial vehicles, the presence of an electronic badge and performing a badge logging transaction in response to detecting the electronic badge. The badge logging transaction includes receiving, by the badge communicator, a badge identifier transmitted by the detected electronic badge. The badge logging transaction also includes determining, by the badge communicator, an offset measurement of the electronic badge relative to the select industrial vehicle, electronically determining a vehicle location of the select industrial vehicle, and identifying a badge location based upon the determined vehicle location and the measured offset. The badge logging transaction can also include generating a time stamp, and wirelessly communicating a badge locator message to a remote server, the badge locator message including the badge identifier, the badge location, and the timestamp.

A cloud-based radio frequency identification system and method for maintaining and providing users with part information for a plurality of parts are provided. The system includes a cloud platform server including a part database storing the part information. The cloud platform server communicates with at least one mobile device and send e-mail and text alerts associated with the part information and also provides the part information through an online website. The system includes a manufacturing network coupled to the cloud platform server. A plurality of manufacturing workstations are disposed at locations at which a plurality of operation steps are carried out and allow for at least one of automatic entry and manual entry of the part information. At least one radio frequency handheld scanner communicates with the cloud platform server through the manufacturing network and scans a radio frequency identification tag of each of the parts.

The utility tracker taught by the present invention is a BLUETOOTH low energy tag, plus a three axis accelerometer which is approximately the size of a quarter. The utility tracker of the present invention can be secured, typically by sticking the dot to an asset by releasable glue or tape. The utility tracker may be stuck to any asset, which could be a fiber optic cable, or any other non-metallic asset that get placed by a utility company, and which can subsequently be detected by a mobile device.

An order re-check system, comprising: electronic tags arranged on turnover boxes; RFID readers/writers arranged on goods allocations, when the turnover boxed are located on the goods allocations, RFID readers/writers acquiring number information of the turnover boxes via the electronic tags; a first information binding module, used for binding the first number information and the second number information in a one to one manner; a second information binding module, used for binding the second number information and orders in a one to one manner; a commodity information acquisition module, used for acquiring commodity information; a commodity information processing module, used for determining an order for a commodity according to the commodity information, and determining the first number information corresponding to the commodity according to a binding relationship between the first number information and the orders; and control indication modules, used for instructing the corresponding goods allocations or turnover boxes.

A system and method for tagging, organizing and tracking evidence during an investigation has evidence kits and mobile communication devices that collect physical, photographic and interpretive evidence, such as materials from a crime scene, interviews with witnesses and an establishing shot of the crime scene or other areas or persons of interest for surveillance operations. The evidence kits can be used to collect physical evidence, and the mobile devices or other computers are used to upload information about the evidence. Users can enter descriptive information about the evidence into the mobile devices while other information pertaining to the evidence may be obtained from other sources and automatically provided to the users for their review and possible incorporation into the record. Each mobile device can store information in memory and communicate the information to the central server computer where it may then be made available to groups of mobile device users.

A multi-layer conductor device is disclosed comprising two or more conductors used in an antenna for a more durable radio-frequency identification (RFID) tag. The conductors interconnect electrically, but are separated mechanically, so a failure in one conductor will not necessarily cause a failure in the other conductor. And, if the failure occurs at different locations on the antenna, the current path through the antenna will bridge the break.

A payment card (e.g., credit and/or debit card) is provided with a magnetic emulator operable to act as a magnetic stripe read-head detector and a data transmitter. A multiple layer flexible PCB may be fabricated to include multiple magnetic emulators. An emulator may include a coil that includes magnetic, ferromagnetic, or ferromagnetic, material in the coil's interior. Coils may be associated with zones. As a read-head is detected to move from zone-to-zone, coils may be activated to transmit information in those zones.

A payment card (e.g., credit and/or debit card) or other card or device (e.g., mobile telephone) is provided with a magnetic emulator operable to communicate data to a magnetic stripe read-head. User interfaces are provided in a number of different configurations in order to achieve a number of different functionalities.

A smart radio frequency identification (RFID) system for controlling operation of electrical units is disclosed. The system includes a RFID tag, a control unit coupled to the RFID tag, a relay unit connected to the control unit and to the electrical unit, and an external RFID reader for generating radio frequency (RF) signals for sending data to the RFID tag when the RFID reader is placed next to the RFID tag. The RFID tag checks and stores the data and passes the data along to the control unit. The control unit sends a control signal to the relay unit in accordance with instructions contained in the data, causing the relay unit to operate the electrical unit between a first state and a second state. The system may also include sensors to monitor certain conditions of the electrical unit and cause the control unit to turn off the electrical unit when the conditions are abnormal.

Systems and methods to selectively attach and control antennas via diodes. In one embodiment, a system includes: a reader having a plurality of reader antennas of different polarizations to transmit radio frequency signals; and at least one radio frequency device. The radio frequency device includes: a plurality of tag antennas of different polarizations; a plurality of diodes coupled to the plurality of tag antennas respectively; a receiver coupled to the plurality of diodes to receive the radio frequency signals from the tag antennas when the diodes are forward biased; and a set of one or more current controllers coupled to the plurality of diodes. In a receiving mode the controllers selectively forward bias the diodes to receive the signals from the reader. In a transmitting mode the controllers selectively change the state of the tag antennas to transmit data via backscattering the radio frequency signals.
