An inventory system configured for detecting and counting potentially retained surgical items within a body of a patient includes an RFID tag configured to transmit a return signal at a frequency when energized, a signal generator configured to generate an energizing signal for the RFID tag, an antenna operably coupled to the signal generator, the antenna configured to receive a return signal transmitted by the RFID tag, an imaging device configured to capture an image, a processor, and a memory. The memory includes instructions stored thereon, which when executed by the processor cause the system to energize the RFID tag, receive the return signal from the antenna, receive the image of the area including the portion of the body of the patient from the imaging device, and determine a spatial location of the RFID tag.

A method includes transmitting, by a radio frequency identification (RFID) reader, a series of RF signals to a plurality of RF receiver circuits in a time sequence. The first RF signal commands the plurality of RF receiver circuits to remain silent when received signal strength of the first RF signal corresponds to a power level greater than a first power level. The method further includes receiving one or more sets of responses from one or more sets of RF receiver circuits of the plurality of RF receiver circuits in response to the series of RF signals. The method further includes determining an area of interest based on the one or more sets of responses, determining a set of power levels corresponding to the area of interest, and transmitting a second series of RF signals to the plurality of RF receiver circuits in a second time sequence.

A connecting method, apparatus of a screen transmission device based on NFC, and a computer device are provided. The connecting method of the screen transmission device based on NFC includes touching an NFC tag, and identifying whether the NFC tag contains network information of the screen transmission device; and when the NFC tag contains the network information of the screen transmission device, acquiring the network information, and connecting with the screen transmission device according to the network information.

In accordance with a first aspect of the present disclosure, a near field communication (NFC) device is provided, comprising: a communication unit configured to be communicatively coupled to an NFC reader; a processing unit configured to use a plurality of emulated cards for executing one or more applications; a profile determination unit configured to determine a polling profile of said NFC reader; and a card selection unit configured to select a specific one of said emulated cards for use by the processing unit in dependence on the polling profile determined by the profile determination unit. In accordance with a second aspect of the present disclosure, a corresponding method of operating a near field communication (NFC) device is conceived. In accordance with a third aspect of the present disclosure, a corresponding computer program is provided.

Technologies are disclosed for providing a virtual control panel for a controlled device using a controller connected to the controlled device via a near-field communications (NFC) connection. The controlled device may include a transfer memory that is connected to a wireless (NFC) port and a wired port, the wired port being coupled to other internal memory of the controlled device. The controlled device may write parameter data to the transfer memory via the wired port, which is later transmitted to the controller via the NFC connection for presentation via a user interface. The controller may receive (e.g., while the controller is connected or disconnected from the controlled device) adjustments to configurable parameters of the parameter data and transmit the adjustments to the transfer memory via the wireless port for updating the internal memory of the controlled device and thereby adjusting operation of the controlled 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. The present method and system determines whether the vehicle is being operated by a user that may also have access to a mobile communication device which, if used concurrently while the vehicle is in operation, may lead to unsafe operation of the vehicle. If the mobile services control system determines that a vehicle operator has potentially unsafe access to a mobile communication device, the mobile services control system may restrict operator access to one or more services that would otherwise be available to the operator via the mobile communication device.

A wearable article, system, and method includes a structure configured to enclose a body part, a first antenna, in a first positon 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 for communicating directly with commodity Wi-Fi transceivers (TRXs) via backscatter modulation in an integrated tag device is provided. The method includes sensing an incident Wi-Fi?compliant wake-up signal. The method than reflects the incident Wi-Fi- complaint wake-up signal by encoding data from the tag device such that the reflected signal follows the Wi-Fi standard compliant and can be decoded by another WiFi-device. An integrated device includes a downlink Wi-Fi compatible wake-up receiver that checks timing of Wi-Fi compatible signals for a wake-up packet. The device has a modulator that is turned on in response to the wake-up packet and a mixer in the modulator hat mixes tag data with a payload packet from received Wi-Fi payload. Backscatter switches backscatter the response.
