    • A method and system to detect a position of a member movable along a defined path is described. The system includes a magnetic source, an array of sensors, and an analyzer. The magnetic source radiates a magnetic field and is coupled to a movable member. The array of sensors is fixed relative to the movable member. Each sensor generates an output response value based on an angle of the magnetic field passing through each sensor. The array of sensors produces a plurality of output response values for a first position of the movable member. The analyzer receives the plurality of output response values and calculates a composite output response value to determine the first position of the movable member.

    • 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.

    • A system and method automatically associate wireless devices to point names. An installation plan indicates that wireless devices are installed at designated locations. Each designated location in the installation plan includes an associated point name, each wireless device is configured to transmit a message indicating itself as the source of the message, and each wireless communication device is installed proximate to its designated location. Expected distances are determined between one or more pairs of designated locations on the installation plan. Range estimate data is gathered from the installed wireless devices for one or more pairs of the installed wireless devices. A unique identifier within a signal transmitted by one of the installed wireless devices is associated with a corresponding point name on the installation plan. The association is determined at least in part by the expected distances and the range estimate data.
