The invention provides a two-sided auxiliary structure for induction cards, which comprises: a metal shield layer; and two high-conductivity magnetic layers, which are respectively set on two opposite sides of the metal shield layer, wherein the area of the metal shield layer is greater than those of the two high-conductivity magnetic layers. The two-sided auxiliary structure for induction cards of the invention improves the problem of poor induction success rate of plural induction cards.

A method of tracking is described. The method may include receiving, from a location device, a location request for an object and identifying a signal from a transponder associated with the object, wherein the transponder comprises at least one or more types of locating technology or sensing technology. The method may also include determining, by a processing device, at least one of the location of the object or information associated with the object based on the identified signal.

A system and method for prominently propagating advertisements and messages from a garment. The system and method provide a washable fabric section that contains a waterproof Near Field Communication (NFC) tag, and a logo label. The NFC tag and the logo label are disposed adjacent to each other, and separated by a fold line for easy visible delineation. The washable fabric section is integrated, possibly through sewing, into the washable fabric section. The washable fabric section, with the NFC tag and the logo is disposed at a prominently visible location on the garment, so as to enable widespread distribution of the advertisement or message through NFC technology. An NFC reader scans the NFC tag to read the data contained therein, which may include a web site, a social media platform, advertisements, and messages.

A zone antenna system includes a zone antenna mat including a substantially planar zone antenna and a zone beacon unit configured to establish a detection zone and detect presence of an electronic tag in the detection zone. The zone antenna system may form part of a compliance monitoring system in which presence of the electronic tag the detection zone is part of a monitored process. The zone antenna system establishes a detection zone, detects entry of one or more electronic tags into the detection zone, and stores and/or wirelessly transmits entry event data corresponding to one or more detected entry events for receipt by a remote or local computing device.

Disclosed herein is a method and system for detecting, monitoring and/or controlling one or more of mobile services for a mobile communication device (also referred to herein as a Controllable Mobile Device or CMD), and in particular, when the device is being used and the vehicle, operated by the user of the device, is moving. In addition, one aspect of the invention generally relates to a method and system for modifying a user's driving behaviors, in particular to a system and method for modifying a user's unsafe driving behaviors, e.g., using one or more services of a controllable mobile device while driving, by providing a score to the user rating indicating that they are using a mobile device in a distracting way, or driving in a manner that indicates that they are distracted.

A wearable article, system, and method includes a structure configured to enclose a body part, a first antenna, in a first position on or within the structure, tuned to communicate according to a wireless communication modality through air, a second antenna, in a second position on or within the structure, tuned to communicate according to the wireless communication modality through the body part, the first antenna being tuned differently than the second antenna, and a transceiver, operatively coupled to at least one of the first antenna and the second antenna, configured to communicate with an external antenna via the at least one of the first and second antennas according to the wireless communication modality.

A method of determining a proximity of an antenna located in a payment instrument to an antenna located within an electronic device may include receiving, at the antenna located within the electronic device, a first signal from the antenna located in the payment instrument, the first signal received at a first time, receiving, at the antenna located within an electronic device, a second signal from the antenna located in the payment instrument, the second signal received at a second time, the second time being later than the first time, determining a difference in a signal strength between the first and second signals, and displaying, on a display of the electronic device, an indication based on the determination.

A Near-Field Communication (NFC)-enabled constrained device (100) is provided. The constrained device (100) comprises a processing circuit (111) operative to implement a functionality of the constrained device (100), an NFC-interface circuit (115) configured to harvest power transmitted by an NFC-enabled control device (200) and to enable exchange of data with the control device (200), when the devices are in proximity, and a restart circuit (121) configured to accumulate electrical charge using the harvested power received from the NFC-interface circuit (115), and to trigger restart of the processing circuit (111) when the accumulated electrical charge exceeds a threshold level. Further provided is an NFC-enabled control device (200) for restarting the NFC-enabled constrained device (100). The control device (200) comprises an NFC-interface circuit (215) configured to transmit power to the constrained device (100) and to enable exchange of data with the constrained device (100), when the devices are in proximity, and a processing circuit (211) operative to initiate the transmission of power to the constrained device (100), and to control the exchange of data with the constrained device (100).

Smart livestock management method and system based on Internet of things. The smart livestock management system may include a gate. The gate may include a frame forming a moving path of an animal, an external device disposed in the frame and configured to radiate electromagnetic waves toward the moving path and to receive identification information and bio information of the animal from an implant device inserted into the body of the animal passing through the moving path, and a camera configured to obtain image data of the animal passing through the moving path.
