A system for providing controls signals to a wireless remote camera comprises a signal generating device that presents forward and inverse polarity pulse trains. A transmitter data converter circuit has a forward polarity input point for receiving the inverse polarity pulse trains and an inverse polarity input point for receiving the forward polarity pulse trains, and converts the forward and inverse polarity pulse trains to a conditioned unitary pulse train. A modulator circuit modulates the conditioned unitary pulse train onto an RF carrier. A demodulator circuit demodulates the modulated output wave to produce a reproduction of the conditioned unitary pulse train. A receiver data converter circuit converts the conditioned unitary pulse train to conditioned forward polarity pulse trains and conditioned inverse polarity pulse trains. A camera control circuit produces control signals based on the conditioned forward and inverse polarity pulse trains. A wireless remote camera receives the control signals.

A body-worn electronic device, including a loop antenna and a transmitter. The overall physical length of the loop antenna is less than 75% of the vacuum wavelength of a lower limit frequency of the operating frequency range of the transmitter, while the electrical length of the antenna is from 0.9 to 1.1 times the guided wavelength of the lower limit frequency of the operating frequency range of the transmitter. The loop antenna includes a plurality of conductors which are connected in series by inductors so as to increase the electrical length of the loop antenna.

Embodiments of the present invention provide a wearable device (200) suitable for wearing on a person's wrist and comprising a metallic housing (203) and a flexible band (202) for attachment of the device to a user's wrist. The metallic housing includes a printed circuit board (PCB) (702) on which is mounted electronic components (710) including a transmitter for transmitting radio signals at a frequency between 400 and 1000 MHz. A coin-cell battery (502) powers the device. The battery is disposed in an inner core (406,406′) of the flexible band. An antenna is connected to the PCB for radiating said signals. In one embodiment the antenna comprises a coil (504,506) of wire disposed in said section of the band. The wire is of substantially a quarter wavelength in length based on the transmission frequency of the radio signals, and comprises the electrical connections between the battery and PCB. In a second embodiment, the transmitter comprises a coaxial cable connector and a coaxial cable having a terminal for connection to said coaxial cable connector. The coaxial cable extends out of said housing into said section to an antenna disposed in said section.

A sport footwear is provided with a tank containing a pressure timed evanescence marker fluid, an opening, from which the liquid is spouted, associated with the tank and regulated by a check valve, electromechanical actuation means comprising a wireless receiving card, suitable for imposing the opening condition of the check valve and actuable by means of remote control means comprising at least one wireless network card. Between the wireless network card and the wireless receiving card a wireless type connection is established, suitable for connecting the control means with the actuation means and for setting the opening condition in the check valve in order to achieve the pressure liquid to be spouted from the opening of the footwear.

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. The guest devices can each include a device health sensor configured for measuring at least one health function of a user wearing the guest device.
