An IC card has a communication unit, a storage unit, and a controller. The communication unit communicates with an external apparatus. A communication buffer for communication between the communication unit and the external apparatus is set in the storage unit. If the size of a buffer used in communication is designated by the external apparatus, the controller sets a receive buffer that stores reception data and a transmit buffer that stores transmission data in the communication buffer, and notifies the external apparatus of the size of the set receive buffer and the size of the set transmit buffer.

A method for execution by a RFID tag includes receiving, from an RFID reader, an RF signal, where the RF signal has a carrier frequency of a plurality of carrier frequencies that span a broad frequency band. The method further includes adjusting input impedance of the RFID tag over a range of input impedances, where the input impedance of the RFID tag is based on one or more of impedance of the RFID tag's antenna and tank circuit. The method further includes monitoring power level of the received RF signal over the range of input impedances. The method further includes selecting the input impedance of the range of input impedances providing a substantially maximum power level of the received RF signal, where the substantially maximum power level corresponds to the carrier frequency being substantially equal to a resonant frequency of at least one of the antenna and the tank circuit.

A marker for locating and identify assets which includes an ultra-high frequency (UHF) radio frequency identification (RFID) tag optimized for use below ground and able to more effectively communicate with a RFID reader through a lossy medium such as soil and air. The markers include a reflector which is sized relatively larger than the tag to help focus the forward pattern of the tag more tightly in a forward direction normal to the spiral surface. In addition, the tag includes a chip configured for the soil in which it is to be buried, and an antenna polarized to match the polarization of an RFID reader antenna that is part of a system that includes the marker and reader.

The present invention discloses a system for managing rechargeable batteries to provide power to electrical vehicles. The system comprises a plurality of charging stations each if the intelligent charger includes at least an intelligent battery charger for charging the rechargeable batteries. The intelligent battery chargers further comprises a battery diagnostic detector for detecting and storing data of designated battery health management parameters. The intelligent battery chargers further comprises a transmitter for transmitting the data of the designated battery health management parameters as wireless signals to a networked server in a battery management center.

In an IC tag issuing apparatus including a plurality of row antenna units arranged by facing the IC tags in multiple rows aligned as an IC tag continuous body in each row, respectively, and conducting communication in an electromagnetic induction method with each of the IC tags of the IC tag continuous body by using a plurality of the row antenna units, a plurality of the row antenna units are arranged in a row direction or in a direction along a conveyance direction of the IC tag continuous body, and each of the row antenna units is electromagnetically shielded except the position faced with the IC tags of the IC tag continuous body (by a shield plate and an antenna case).

The present invention relates to a method of manufacturing a metal foil laminate which may be used for example to produce an antenna for a radio frequency (RFID) tag, electronic circuit, photovoltaic module or the like. A web of material is provided to at least one cutting station in which a first pattern is generated in the web of material. A further cutting may occur to create additional modifications in order to provide additional features for the intended end use of the product. The cutting may be performed by a laser either alone or in combinations with other cutting technologies.

An ultrasonic machining device (1) for machining a workpiece. At least one component, selected from the group including a generator (11), a converter (12), a booster (13), a sonotrode (14), a HV cable (15), a machine frame (16) and a receiving device for the workpiece (17), is/are assigned an identifier (18). The identifier (18) characterizes at least one individual parameter of the component. The device (1) is assigned an input interface (19) which reads in the identifier (18) or generated data from the identifier. The device (1) is assigned a data processing arrangement (20). By way of the data processing arrangement (20), based on the read-in identifier (18) or the data generated from the identifier (18), at least one parameter of the device (1) is determined in such a way that the device (1) is operated in a target operating state, e.g., a resonant vibrating state.

A communication device according to the disclosure includes: a signal generator that generates, on the basis of the first signal received from a communication partner through a coil, a second signal that synchronizes with the first signal; a first modulator configured to be able to modulate the first signal on the basis of the second signal; a second modulator configured to be able to modulate the first signal; and a communication controller that selects, on the basis of the first signal, whichever modulator is to be operated, from the first modulator and the second modulator.

A transaction card having a metal layer, an opening in the metal layer for a transponder chip, and at least one discontinuity extending from an origin on the card periphery to a terminus in the opening. The card has a greater flex resistance than a card having a comparative discontinuity with the terminus and the origin the same distance from a line defined by a first long side of the card periphery in an absence of one or more strengthening features. Strengthening features include a discontinuity wherein one of the terminus or the origin are located relatively closer to the first long side of the card periphery than the other, a plurality of discontinuities wherein fewer than all extend from the card periphery to the opening, a self-supporting, non-metal layer disposed on at least one surface of the card, or one or more ceramic reinforcing tabs surrounding the opening.

Theft of an item from a department of a venue having a department-specific, point-of-sale (POS) station for completing a transaction of the item prior to authorized removal of the item from the department, is deterred by sensing and tracking movement of a target associated with the item from the department by deploying a plurality of sensing units overhead at the venue, and by generating an alert when the sensing units sense and track that the target associated with the item has bypassed the department-specific POS station without the transaction having been completed for the item at the department-specific POS station. Security personnel execute a theft-deterrent action in response to the alert.
