A guest engagement system and associated methods provide seamless engagement with guests of facilities through the use of wireless sensing technologies. The system makes use of individual guest devices which are carried by guests and used to automatically identify and authenticate the guests throughout the facility. Services can thereby be seamlessly provided to the guests throughout the facility. The services include automatic unlocking of doors, including hotel or state room doors, based on the guests' immediate proximity to their assigned room's door. The services also include automated payment services provided at checkout or vending terminals, and automated log-on to interactive displays and portals, among others, based on secure wireless authentication of the guest devices.

One example discloses a wireless device, comprising a near-field transceiver configured to be coupled to a host structure; a controller coupled to the transceiver; wherein the near-field transceiver includes a feed point configured to be coupled to a conductive surface; wherein the conductive surface is configured to be capacitively coupled to the host structure to form part of a near-field electric antenna; and wherein the conductive surface is configured to be in repeated, but not continuous, contact with a ground.

A control device for a building management system (BMS) including a touch screen display configured to mount to a mounting surface, a communications interface configured to communicate with the BMS, a near field communication (NFC) sensor configured to receive information from a NFC device, a microphone configured to detect vocal input, and a processing circuit coupled to the touch screen display. The processing circuit including a processor and memory coupled to the processor, the memory storing instructions thereon that, when executed by the processor, cause the control device to receive user input from at least one of the touch screen display, the NFC sensor, or the microphone, validate an identity of a user based on the user input, and cause the BMS to control an environmental variable of a space based on the validation.

A method for transmitting at least one of electrical power and signals between a wall and a leaf which can be pivoted relative to the wall. The method includes providing a transmission device, detecting a magnetic field strength in surroundings of the transmission device, and generating a fault signal when the magnetic field strength exceeds a threshold value.

Disclosed systems and methods include electronic devices attached to a patient or object that transmit data to other devices over a secure communication channel. The devices can track and/or monitor object(s) and/or patient(s) and transmit the tracked and/or monitored data to other electronic devices. Such data can include monitored patient physiological parameter(s) received and/or sensed by the device, for example. A master of the two devices transmits a communication signal to another device that, in response, initiates a secure wireless communication channel, causes one or more modules on the device to be powered, and, when powered, transmits the tracked and/or sensed physiological data over the secure wireless communication channel to the master device. Some example master devices transmit the communication signal with an instruction to the device to activate an onboard power source that later may be disconnected after the tracked and/or physiological data is transmitted.

An antenna device includes a magnetic body and first and second antennas. The first coil antenna includes a first opening and is provided on a first main surface side of the magnetic body. The second coil antenna includes a second opening partially superposed with the first opening. The second coil antenna includes first and second coil conductor portions. The first coil conductor portions are provided on the first main surface side of the magnetic body. The second coil conductor portions are provided on a second main surface side of the magnetic body. The second coil conductor portions are closer to the first coil antenna than the first coil conductor portions.

A power monitoring device is configured to monitor the aspects of power being supplied to an RV at an RV park. The power monitoring device communicates wirelessly to a remote device of a user to provide information about the power supplied by the park. The user can set limits of various power aspects. If aspects of the power supplied are out of compliance with the limits a notification of such may be delivered to the user's remote device.

An input device is provided. The input device comprises a printed circuit board (PCB) assembly comprising: touch sensors configured to detect a user input from a user; a haptic coil configured to provide haptic feedback to the user in response to detecting the user input; and a near-field communication (NFC) antenna configured to facilitate NFC communications, wherein the haptic coil and the NFC antenna are on a same PCB of the PCB assembly.

Methods for operating a communications device that communicates via inductive coupling, methods for operating an NFC device, and a communications device that communicates via inductive coupling are disclosed. In an embodiment, a method involves at the communications device, shifting a first transmission phase to obtain an updated transmission phase in response to information from a corresponding reader device, which indicates that active load modulation (ALM) communications between the communications device and the corresponding reader device under the first transmission phase fail, at the communications device, conducting subsequent ALM communications with the corresponding reader device under the updated transmission phase, in response to that the subsequent ALM communications under the updated transmission phase are successfully conducted between the communications device and the corresponding reader device, obtaining a new training data point based on the updated transmission phase, and training the communications device in response to the new training data point.

A method and system for receiving digital artifacts from a management server. The method includes sending a request for a digital artifact from a mobile application to the management server for display within a specific mobile application generated screen, receiving the digital artifact from the management server, and displaying the digital artifact with the specific mobile application generated screen.
