Abstract: A laptop computer is comprised of a base portion, a display portion, and a scanning/illuminating mechanism. The scanning/illuminating mechanism illuminates a display of the display portion of the laptop computer and illuminates a document during scanning of the document.

Abstract: In accordance with the principles of the present invention utilizing a first radiation monitoring module, radiation information associated with the first radiation monitoring module within a tunnel is wirelessly transmitted to a second radiation monitoring module. The second radiation monitoring module is able to receive radiation information from the first radiation monitoring module for relay of the received radiation information to a central monitoring system. The radiation monitoring modules of the present invention allow long term monitoring of a tunnel's radiation levels with maintenance simply requiring replacement of a non-operational tunnel monitoring module by a robot.

Abstract: A photoelectric cell powered based security system relies on a photoelectric cell powered detector to transmit security information to a main control panel. An optional extender relays security information between a local photoelectric cell powered detector and a main control panel in the event that the local photoelectric cell powered detector is unable to directly communicate with the main control panel.

Abstract: An RFID based security system detects a lock/unlocked condition when securing a premise and an open/close condition of a window and/or door to monitor for an intruder. A local interface polls a RFID tag and relays a read value to a user panel for a determination if an intruder has opened a window and/or door. Alternately, the local interface is connected to at least one of a second local interface and the user panel to form a security network. The security network is relied on to convey security information to the user panel for a determination if an intruder has opened a window and/or door.
