Patent 7958971 was granted and assigned to Otis Elevator Company on June, 2011 by the United States Patent and Trademark Office.
A wireless, portable call request entry kiosk (14) has a control panel (19) with keys (20, 21) and a display panel for entering calls and informing passengers of the responding elevator. The kiosk has wireless communication (42, 56) with a building (43) where the kiosk is located, to transmit call requests to a dispatching controller (48). The kiosk operates on a rechargeable source such as a battery (51). A sensor (52) determines a lull in traffic, causing the kiosk to operate in a low power consumption mode.
