A patient support apparatus tracking system includes at least one of a frame, mattress, and mattress cover. A radio-frequency identification (RFID) tag may be embedded within the at least one of the frame, mattress, and mattress cover. The RFID tag may include an identification memory unit including read-only sort-prefix data corresponding to the one of the frame, mattress, and mattress cover and a service memory unit comprising a read/write configuration including a greater amount of digital storage than the identification memory unit. The RFID tag may be configured to receive a log of configurable equipment updates into the service memory unit and communicate the sort-prefix from the identification memory unit and the log of equipment updates to a controller via a reader device.

A communication device includes an antenna, a driving unit, a first acquisition unit, an input unit, and a second acquisition unit. The driving unit moves a position of the antenna. The first acquisition unit acquires tag data of each radio tag based on a radio wave of each radio tag received by the antenna at a plurality of positions of the antenna. The input unit inputs the tag data of each radio tag at the plurality of positions of the antenna into a learned model. The second acquisition unit acquires, from the learned model, data indicating whether each radio tag is included in a first range or a second range based on the input of the tag data of each radio tag into the learned model by the input unit.

A host unit in a wireless power transmission system transmits power to a secondary unit during a communication-directivity control period and a power transmission period that are temporally divided from each other. The host unit transmits power such that a transmission output power of a power transmission radio wave during the power transmission period is greater than a transmission output power of a communication signal during the communication-directivity control period.

A method is provided for differentiating one of a plurality of unpowered NFC transmitting devices for NFC communication with a receiving device. Each NFC transmitting device has a transmitter NFC interface and an NFC communication range. A range extending device has a power source, a transmitter communication interface, a range extender antenna, and an amplifier. One of the transmitting devices is selected and the range extending device is connected to it so that the transmitter communication interface engages the transmitter NFC interface of the selected transmitting device. This action serves to establish an extended communication range for the selected NFC transmitting device. The NFC transmitting devices are then positioned at a distance from the receiving device that is within the extended communication range, but outside the communication ranges of the other NFC transmitting devices. NFC communication is then established between the selected NFC transmitting device and the receiving device.

A coil assembly includes: a connection substrate including a coil pad and an accommodating portion disposed in a position adjacent to the coil pad; and a coil portion including a spiral wiring and an end portion bonded to the coil pad, wherein at least a portion of the coil portion is disposed in the accommodating portion.

In an embodiment, a system includes a contactless reader and an apparatus. The apparatus includes a contactless transponder including a contactless interface and a transponder wired interface and being configured to communicate with a contactless reader according to a contactless protocol through the contactless interface. The apparatus includes a bus coupled to the transponder wired interface, and at least one module coupled to the bus, the at least one module including a processing circuit, the contactless reader being configured to communicate instructions of a software program executable by the processing circuit to the at least one module through the contactless transponder.

Signal power management circuits and smart cards including the same are provided. For example, a signal power management circuit comprises a rectifier that is configured to rectify a received radio frequency signal and output a first rectified voltage, a first regulator that is configured to maintain the first rectified voltage at a predetermined first voltage level, and a second regulator that is configured to receive an output of the first regulator and maintain a second rectified voltage different from the first rectified voltage at a predetermined second voltage level. A signal detector of the signal power management circuit is configured to receive the first rectified voltage and the second rectified voltage and detect a signal component of the received radio frequency signal on the basis of a difference between the first voltage level of the first rectified voltage and the second voltage level of the second rectified voltage.

A backscatter tag device includes, in part, a receiver configured to receive a packet conforming to a communication protocol defining a multitude of codewords, a codeword translator configured to translate at least a first subset of the multitude of codewords disposed in the packet to a second multitude of codewords defined by the protocol in response to a data the backscatter tag is invoked to transmit, and a transmitter configured to transmit the packet supplied by the codeword translator at a frequency different than the first frequency at which the packer is received. The communication protocol may optionally be the 802.11 g/n, ZigBee or the Bluetooth communication protocol.

Disclosed is a device for storing elements each including a first wireless communication unit, the device including: —a receiving support receiving the elements; —a second wireless communication unit generating waves and communicating with each first unit according to a communication protocol, a communication zone being a three-dimensional zone in which the second unit communicates with each first unit when each first unit is located in the zone and does not communicate with a first unit when the first unit is located outside the zone; —a waveguide able to guide the generated waves so that a dimension of the communication zone is strictly greater than a reference dimension, the reference dimension being equal to the dimension of the communication zone when the storage device is without waveguides.
