A medical instrument is provided in which a wireless IC tag is fixed to a first or second body, such that at least part of the wireless IC tag is positioned more frontward than a front end of a first ring and a front end of a second ring and more backward than a support. A winding axis of an inductor is orthogonal to the up-down direction and intersects the front-back direction so that electric, magnetic, or electromagnetic field coupling is established between a resonant circuit and a metal medical instrument. Moreover, the metal medical instrument either emits a transmission signal, which has a frequency equal to a predetermined resonant frequency and supplied from the resonant circuit, as an electromagnetic wave, or it receives a reception signal having a frequency equal to the predetermined resonant frequency as an electromagnetic wave, and supplies the reception signal to the resonant circuit.

A biometric sensor module for detecting a biometric feature of a user comprises: a biometric sensor comprising an array of sensing elements for acquiring sensing signals indicative of a biometric feature of a user, the array of sensing elements arranged facing towards a front side of the biometric sensor. Further, the biometric sensor module comprises a bottom flexible film attached to a back side, opposite the front side, of the biometric sensor. The bottom flexible film can carry at least one electrically conductive line electrically connectable to the biometric sensor and electrically connectable to an external electrical circuit. The biometric sensor module further comprises a top film attached to the biometric sensor closer to the front side of the biometric sensor than the bottom flexible film. The flexible film includes a bent portion such that the flexible film is bent towards the top film.

Systems and methods are provided for conveyor operation and maintenance that employ one or both of a “smart shoe” technology where one or more conveyor shoes incorporate features, such as an RFID tag, and a “missing pin detection” technology where one or more pin components of conveyor shoes incorporate features, such as an RFID tag, allowing selective wireless tracking and identification capability. A conveyor system comprises a shoe management system allowing interactions directly with one or more RFID readers, which can detect, store and/or monitor information associated with “smart shoe” and/or “missing pin detection” RFID tags, where interface between this application and the reader can be implemented via a socket interface. An open platform communications (OPC) wrapper can be created around the interface so that a Human Machine Interface (HMI) could interact directly with shoe management system.

A sheet processing apparatus for processing sheets each with a wireless tag, includes a roller, a wireless tag reader/writer, and a controller configured to control the roller to convey a first sheet with a first tag along a path, control the reader/writer to acquire first strengths of radio signals received from the first tag during the conveyance and second strengths of radio signals received from wireless tags of sheets not being conveyed, determine a threshold value of signal strength for distinguishing a wireless tag being conveyed from wireless tags not being conveyed based on the first and second strengths, and control the roller to convey a second sheet with a second tag and control the reader/writer to write to the second tag when a strength of a radio signal from the second tag is greater than or equal to the threshold value.

Disclosed is a method of gathering data from a hybrid RFID chip to determine usage of an item or article of clothing using a mobile device like a phone, laptop, or tablet. The hybrid RFID chip consists of a processor, a memory, a radio transceiver, a power harvesting antenna, and an impedance circuit that converts ambient radio frequency (RF) energy to electrical energy. The RFID chip receives a first power level from ambient RF energy and periodically broadcasts an identity. The mobile device can receive the broadcast identity, store the identity, transmit the identity and location to a remote server, and receive a notification message from the remote server. The remote serve can determine usage of the item or article of clothing by comparing current records to previous records of RFID chip identity, location, and mobile device application identity.

A modulation scheme conversion device includes: a backscattering tag to which a tag signal is provided; and a tag signal forming unit for forming a tag signal. The modulation scheme conversion device multiplies a radio signal, which has been modulated in a first modulation scheme, and a tag signal, and reconfigures the multiplied signal by using a second modulation scheme, so as to backscatter the reconfigured signal, wherein the reconfiguration is performed in a physical (PHY) layer.
