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 contact tracing, 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.

Antenna devices and methods for making and using the same are disclosed. An exemplary antenna device can include first and second wireless communication antennas configured to operate using first and second communication standards, respectively.

Implementations of a child safety system is provided. Implementations of a child safety system comprises portable transmitter configured to transmits a wireless signal compatible with Bluetooth technology and a portable computing device configured to receive the wireless signal and compute a distance between the portable computing device and the transmitter based on the signal strength of the wireless signal received. The portable computing device further is configured to sound an alarm on the portable computing device once the distance between the portable computing device and the portable transmitter equals or exceeds a preset distance.

The invention relates to a protective helmet, and in particular, to a protective motorcycle helmet, comprising an antenna (1) for radio transmission, an outer shell (2) for distributing impact forces, an inner layer (3), which is accommodated by the outer shell (2), for damping impact forces, and a socket (4), which is firmly connected to the outer shell (2), for contacting a digital device (5) for wireless communication, wherein the socket (4), when contacting the digital device (5), electrically connects the latter to the antenna (1) for wireless communication. The protective helmet is characterized in that at least a partial layer of the outer shell (2) is disposed between the antenna (1) and the inner layer (3).

A Computer-Aided Dispatch (CAD) system is specially configured to account for the physical condition of emergency personnel, which can affect their ability to effectively handle a particular incident. The CAD system tracks health, stress, and biometric status of each available emergency responder automatically and in real-time based on a wide range of collected information and to assess the suitability of available emergency responders to respond to a given emergency incident based upon such status information. Based on such status information, the CAD system can make intelligent recommendations to the emergency dispatcher by taking into account such things as the emergency responder's past experiences with a particular type of emergency incident, the current and cumulative status of the emergency responder, and projections as to the future condition of the emergency responder if dispatched to handle the emergency incident.

An electronic device is configured to perform electric field communication via an electric field transmission medium. The electronic device includes a housing. The electronic device also includes a first electrode portion for electric field communication including a first electrode and a second electrode, a second electrode portion for electric field communication including a third electrode and a fourth electrode, and a differential amplifier. The second electrode is disposed further in a direction towards the inside of the housing than the first electrode. The fourth electrode is disposed further in a direction towards the inside of the housing than the third electrode. The first electrode and the second electrode are connected to a first input terminal of the differential amplifier. The second electrode and the fourth electrode are connected to a second input terminal of the differential amplifier.

An eyewear device that includes a lens; a support structure adapted to be worn on the head of a user, the support structure including a rim configured to support the lens in a viewing area visible to the user when wearing the support structure; an antenna embedded into or forming part of the support structure, the antenna at least partially extending into the rim; a transceiver adapter to send and receive signals; and a tuner coupled between the transceiver and the antenna, the tuner adapted to match impedance between the antenna and the transceiver to improve power transfer.

A high-frequency antenna, such as may be implemented in a mobile computing device, is sensitive to obstructions that interfere with, and attenuate, a signal emanating therefrom. In fact, in mobile communication devices, such as cellular telephones, a user's hand, or even clothing, can attenuate the signal to cause a noticeable degradation in the quality of service of the device. To alleviate this, a mobile computing device is configured to detect the attenuation and provide a notification to a user to alleviate the situation. In some cases, the user is prompted to hold the mobile computing device in a different orientation in order to remove the obstruction. The prompting may be provided through visual, audio, haptic, or other types of feedback, including dispersing heat generated by the mobile computing device near the antenna location so it become uncomfortable for the user to hold the device in a way that interferes with the antenna system.
