摘要:
A system for guidance and navigation in a building. For example, the system may determine a route for egress or rescue of one or more people from a building with a hazardous condition. The system may process the route into waypoints and segments developed within a set of constraint rules. Semantic information about the building may be associated with the waypoints and/or segments. The waypoints and segments may be processed into navigation commands. The navigation commands may be formed in natural language from sentence templates. The system may additionally have 3D beacon audio to assist in guidance and navigation of the one or more people in the building.

A method for enhanced location sensing based on topology constraints. A potential position value and a corresponding probability value with respect to an observed position data of an object within a structure can be calculated utilizing a normal probability distribution function. Thereafter, an optimal route between adjacent observed time periods may be calculated utilizing a heuristic search algorithm. The potential position value and the optimal route can be calculated by accessing a pre-installed topology data associated with the structure. An optimization problem can then be solved to refine the observed position data. The position between a pair of observed time periods can be interpolated and the position of the object before a next observed time can be predicted by interpolation based on the spatial constraints.

A method of mapping the location of at least one object in three dimensional space, relative to an initial point in three dimensional space by an EIR terminal which contains a microprocessor, memory, a scanning device, a motion sensing device, and a communication interface. The method includes scanning a signal of decodable indicia located at a pre-defined area of a physical object, locating the decodable indicia within this signal, decoding the decodable indicia into a decoded message. The decoded message is an identifier for said physical object, which is then displayed. After receiving an interface command, the EIR terminal is placed in mechanical contact with the pre-defined area of the physical object and a first spatial position is stored as a point of origin in the EIR terminal.
