Abstract
A potential elevator passenger or occupant (bearer) carries a portable transmitting device with which he must overtly indicate his intent to take an elevator trip before interrogation by a beacon will cause an elevator call to be automatically registered for him, or indicate his intent before gaining access to a space. The intent to take a trip is cancelled when the bearer enters an elevator car, requiring an additional overt act prior to entering an automatic elevator call the next time that the bearer approaches an elevator. Default destinations (floors or spaces) may be signified for the bearer, depending on the floor where the device is located, or the bearer may establish an alternative destination, the alternative destination being cancelled from the device when the bearer enters an elevator or gains access to a space. The intent may be managed and a default destination may be provided either by the portable device or by a system in the building. Authentication of the bearer's voice may precede provision of the token. Tokens may be manifested by the presence alternative destinations.
