Abstract: An elevator control system (18) provides elevator dispatch and door control based on passenger data received from a video processing device (12). The video processing device (12) includes a video processor (14) connected to receive video input from at least one video camera (10) and memory (16). The video processor (14) anonymously monitors passengers using color index analysis of each passenger. Based on the monitored position of each passenger, video process (14) calculates passenger data parameters such as location, direction, speed and estimated time of arrival at an elevator door, and provides one or more of the passenger data parameters to elevator control system (18). Based in part on the passenger data received, elevator controller (18) provides elevator dispatch, elevator door control, and security functions.

Abstract: An elevator system (10) includes a wireless batteryless hall call switch module (22) that transmits a unique wireless code when a person presses a hall call button (32, 34) requesting elevator service. A hall indicator module (24) includes an RF transceiver (64) that receives the wireless code from the switch module (22), activates a display to indicate that a button has been pushed, and transmits the hall call information to the elevator control system (14). When the elevator controller (14) informs the transceiver (64) of car arrival, the hall indicator module (24) causes the display to indicate car arrival.

Abstract: A positioning system having a plurality of transponder modules each located at a known location for receiving an electromagnetic signal and emitting a light signal, at least one transceiver module for emitting an electromagnetic signal and receiving the light signal, and apparatus processing the received light signal to determine a position of the at least one transceiver module.

Abstract: An apparatus and method for measuring a position of a moveable platform comprising a plurality of RFID tags encoded with location information situated at known locations and a plurality of visual markers situated at precise, known locations. An RF reader attached to a moveable platform reads the RFID tags to determine the approximate location of the platform. A camera apparatus attached to the moveable platform scans the visual marker. The scanned image is processed to provide the precise position information of the platform.

Abstract: A method of providing non-contact data selection, comprising the steps of providing at least one data selection, transmitting at least one signal in proximity to the at least one data selection, altering the path of the at least one transmitted signal through interaction with a selection device, detecting at least one altered signal, and determining selection of the selection device from the at least one altered signal.
