A wireless communication device including: a memory that stores a setting content of a beacon terminal to be rewritten, identification information of the beacon terminal, and a flag indicating whether the setting of the beacon terminal has been already rewritten, the setting content, the identification information and the flag being associated with each other; and a processor coupled to the memory and the processor configured to: acquire data broadcasted from the beacon terminal; and transmit the setting content to the beacon terminal, and cause the beacon terminal to change the setting when identification information of the beacon terminal included in the data acquired from the beacon terminal is identical with the identification information stored into the memory, changing the setting of the beacon terminal is not completed and a strength of a received signal from the beacon terminal is equal to or more than a threshold value.

Accessories for an electronic device and methods are described. The accessory comprises a substrate configured to be removably attached to the electronic device and a near-field communications (NFC) tag attached to the substrate and configured to transmit interaction data in response to receiving a signal from a separate electronic device. The interaction data causes the separate electronic device to access user data associated with a unique user account.

Devices, systems, and methods enhance the inspection of internal areas and occupants of vehicles, and can employ one or more high-resolution cameras, one or more auxiliary illumination devices and a related computer system. According to various embodiments, an auxiliary illumination device can be synchronized to one or more cameras, and configured to supply auxiliary illumination to facilitate capture of accurate and usable images. Advanced image processing solutions assist with identifying individuals inside a vehicle, removing light glare and undesired reflections from a window surface, and capturing an image through a tinted window, among other things. Further, embodiments can compare a captured image to an authenticated image from a database, so as to confirm the identity of a vehicle occupant.

A method for bulk encoding of RFID tags. The method may include printing a plurality of unencoded RFID labels, coupling each of the plurality of unencoded RFID labels to each of a plurality of products, packaging like products from the plurality of products coupled with the unencoded RFID labels together in a container, scanning the container holding the products with an RFID antenna, and encoding each of the unencoded RFID labels coupled to each of the plurality of like products in a container simultaneously with identical information for each container.

A method and system for estimating position of a moving RFID tag is provided. The method includes transmitting at least one interrogator signal; receiving, at an interrogator antenna, a reflected signal from the RFID tag; determining phase changes of the reflected signal with respect to the phase of the at least one interrogator signal; weighting the phase changes based on instant power corresponding to the phase changes; producing a phase trajectory for the reflected signal based on the weighted phase changes; and estimating position of the RFID tag relative to the interrogator antenna based on the peak of the phase trajectory for the reflected signal.

A RFID system includes an RFID controller incorporating a serial bus master coupled via a serial bus to a serial bus slave device, whereby the RFID controller controls power supply and/or power mode of the salve device in order that the slave device is powered and able to communicate with the RFID controller in response to RFID commands received from an RFID reader, and unpowered or in a low power mode otherwise.

A system for determining a bearing or location of a radio frequency identification (RFID) tag using a handheld RFID reader is described. In one embodiment, the reader is equipped with an accelerometer. A user moves the reader while the reader receives the tag's signal and determines the tag signal's phase at multiple locations. The locations of the reader antenna can be reconstructed using the accelerometer data. By using the phase determined at multiple locations in conjunction with the location of the reader antenna, the reader can determine the bearing of the tag. For an RFID reader not equipped with an accelerometer, the sign and ratio of the rate of change in the phase of a tag's signal to the distance traveled by the reader antenna can be used to determine the location of the tag relative to the reader.

A system simultaneously tracks multiple objects. All or a subset of the objects includes a wireless receiver and a transmitter for providing an output. The system includes one or more wireless transmitters that send commands to the wireless receivers of the multiple objects instructing different subsets of the multiple objects to output (via their respective transmitter) at different times. The system also includes object sensors that receive output from the transmitters of the multiple objects and a computer system in communication with the object sensors. The computer system calculates locations of the multiple objects based on the sensed output from the multiple objects.

In one embodiment, a system includes a HMI module. The HMI module includes a first external application unit that has first external application unit. The first external application unit has a first interface for the HMI module. The HMI module further includes a second external application unit that has a second interface for the HMI module. The HMI module can correspond with both the first interface and the second interface.
