Title:
DOOR WITH A SAFETY ANTENNA
Document Type and Number:
WIPO Patent Application WO2004113662
Kind Code:
A8
Abstract:
A door system (10) includes an antenna-based proximity sensor with a releasable electrical connector (14) that enables the sensor to function with a breakaway feature of the door. The sensor includes a signal generator (44) and a door-mounted antenna (38) for sensing a body or an obstruction near the door. The signal generator ( or oscillator) can be installed at various locations between a power source (46) and the antenna. In some cases, the wiring between the antenna and the power source includes a rotatable feature to accommodate the rotation of a drum that carries a wrap-up, pliable door panel. The rotatable feature may be a rotatable electrical connector, or it may be a wire having sufficient length and flexibility to twist about itself within the hollow interior of the drum.
