Abstract: A system and method for determining the status of an authorization device over a network. Output signals indicative of the status of the authorization device are stored in a status file. An authorization datastore accesses the status file over the first network and obtains the status of the authorization device. A determination is made from the user identifier if the user is authorized to use the controlled device. Permission is granted to the user to use the controlled device if the user is determined to be authorized to use the controlled device.

Abstract: A system and method for monitoring the state of a structure over a network. The system and method provides for providing the status of a monitoring device to a status file. The status file is accessible over the Internet by computer so that a party can first determine the status of the device. The system operates over normal PSTN's, over cable systems, over wireless networks and over the Internet.

Abstract: A status monitoring system utilizing an RFID tag. In an embodiment of the present invention, a status of a receiving device comprises a device address, whether the device is able to receive communications from a sending device, and a recipient list of users able to use the receiving device at any particular time. In an exemplary embodiment of the present invention, the recipient list is created by the receiving device in response to the detection of a qualified user within a preset access distance of the receiving device. A sending device may access this status information and determine how to communicate with a user on the recipient list.
