Secure, verifiable, computer-enabled, LAN/WAN/Wireless networked, facility emergency notification, rapid alert management, and occupant alarm systems for public, private, and government buildings, and outdoor areas for which there is a need for rapid alerts to occupants or attendees of the occurrence of impending or in-progress dangerous or threatening events. The inventive system is a highly flexible rapid alert initiation, management and archival system comprising computer-enabled and network-linked apparatus, software, and methods enabling rapid dissemination from a central station or decentralized location of alerts of the occurrence of threatening or dangerous events in a series of hierarchical, increasing levels of directed action to be taken by the occupants, and permits monitoring and controlling activity of occupants during the event, archiving event data, including audio or/and video recordings until the situation returns to normal and an all clear signal is given. Databases provide site plans to assist in the response planning and execution.

A system monitors and detects unauthorized wireless LAN access points and wireless devices. The system includes one or more wireless LAN monitoring devices, which detect and report the presence of unauthorized or “rogue” wireless LAN access points or wireless devices within a predetermined area, for example, within the vicinity of a wired LAN, including indoor and/or outdoor areas. Improved range is achieved through the use of preamplification and sectorized antennas. Larger areas may be covered using additional wireless LAN monitoring devices, which operate independently or cooperate together in the detection process. Geolocation is possible using single or multiple, cooperating monitoring devices. Provision can be made for monitoring devices to provide packet filtering on a wired LAN.

A system for locating a wireless device involves the use of the measured signal strength of various base stations in the building or outdoor area under analysis. A topological map of the building or outdoor area under analysis is created. The map is divided into cells, and signal intensities are collected in each cell. For each cell, the signal from a particular base station is fit to a statistical distribution, such as a Gaussian distribution, and the parameters of the statistical distribution are estimated. After a device obtains a set of signal strength measurements, a probabilistic technique is employed to estimate the probability of the existence of the measurements in each of the cells of the building or area under analysis. The estimated location is the cell with the highest probability. A mobile user is tracked with the use of a Markov chain and the system can be calibrated to account for equipment and environmental variations.

A first pilot signal is transmitted at a first frequency for a first coverage area (e.g., an outdoor area). A second pilot signal is transmitted at a second frequency for a second coverage area (e.g., an indoor area). The first pilot signal at the second frequency is transmitted into a portion of the second coverage area, the second coverage area at least overlapping with the first coverage area. Further, the first pilot signal is transmitted at the second frequency in the second coverage area. In an example, the first pilot signal at the first frequency is transmitted from an outdoor base station, the second pilot signal at the second frequency is transmitted by an indoor base station, the first pilot signal at the second frequency is transmitted into the second coverage area (e.g., an interior of a building from a building exit point) by an antenna (e.g., not necessarily at a base station) and the second pilot signal at the first frequency is transmitted by the indoor base station. The pilot signal configuration discussed above may facilitate call handoffs between the first and second coverage areas. For example, if the first coverage area is an outdoor area and the second coverage area is a building interior, the example pilot signal configuration may reduce pilot pollution.

The invention discloses a low power consumption wide area network technology and Mesh fusion-based ubiquitous access method and an application system. 4G network signals in an outdoor area or an indoor area where terminal devices are deployed densely are poor.

A full size building having three walls, an open side and a roof but no floor can be moved along parallel rails from an open free standing position to a closed position where the building abuts another structure to completely enclose an outdoor area. The building is of conventional construction but is erected over a rigid framework of iron beams. A series of roller assemblies containing rotatable axles is attached to the underside of rigid framework. The axles rest directly on the rails and rotate smoothly by means of bearings as the building moves along the rails. Stabilizers prevent wobble and keep the building on the rails when it is being moved. Locks prevent any movement when the building is in either the open or closed position. Additional locking means prevent lateral movement when the building is locked in the open position. The building can be moved using a winch and cable system or using a unique suspended sprocket wheel and track system. Concrete footings form the base for the rails. Hinged panels along the lower portion of the inside and outside of the three walls conceal the roller assemblies and stabilizers and close any space between the walls and the ground below them. The hinges enable the panels to be raised when the building is being moved. The abutting structure can be a stationary wall, an exterior wall of a stationary building, or another movable building.

The present invention provides an unconventional and proprietary radio control (RC) or infrared remote control (IR) toy model/airplane which can intentionally shift or change its center of gravity (COG) to different positions along the longitudinal centerline of the aircraft or fuselage. The incremental shifting or moving of the COG from front to rear or vice versa incrementally changes the “angle of attack” of the wing, thereby producing a variable range of viable flight attitudes and resultant terminal velocities (top speeds). Therefore, users can easily select an appropriate speed for the airplane to fly in limited indoor spaces or in larger outdoor areas. Additionally, the COG shifting of the present invention can be applied not only to RC and IR controlled toy models/aircrafts but may also be implemented into real aircrafts including manned and unmanned aircraft for civilian and/or military applications.
