Abstract: A method of analysing and tracking machine systems has the steps of sensing operational data from equipment, the operational data comprising at least location, time, and one or more operational condition data related to the equipment; analysing the operational data to identify data patterns; logging the data patterns as events in a database; comparing the events to a database of predetermined patterns to classify each data pattern as a known event or an unknown event; updating the database to include a new data pattern related to any unknown events; and alerting a user to further classify the unknown events manually.

Abstract: A method of controlling media projectors includes providing at least one electromagnetic detector having a field of view directed toward a three dimensional space, and photogrammetrically characterizing at least a portion of the field of view. There is provided at least one media projector that projects at least an electromagnetic signal and a projection controller that moves one or more media projectors in at least two dimensions. At least three measurement locations are obtained within the at least a portion of the field of view by moving the media projector in at least two dimensions. The at least one electromagnetic detector is used to detect the measurement locations within the three dimensional space using the electromagnetic detector to obtain photogrammetric data. The projection controller is calibrated based on the photogrammetric data.

Abstract: A system and method for automatically tracking objects of interest and aiming or pointing a device capable of pan/tilt movement at the objects as they move in real-time. The system also provides the capability to gather, in real-time or non-real time, information to calculate the position and orientation in three dimensions of the aiming or pointing device. The position and orientation information is characterized by three positional coordinates (x,y,z) and three angular orientation coordinates (Theta, Gamma, and Phi) for a total of six degrees of freedom or 6DOF.

Abstract: A system is provided for tracking the three-dimensional position of an object within a three-dimensional region by triangulation techniques to generate signals corresponding to such three-dimensional positions. The signals may be used to operate a variably operable system to create a virtual reality system. The triangulation means may comprise at least three ultrasound emitters cooperating with ultrasound receivers located on a body moving in the three-dimensional region. The signals are produced from multiplexed frequencies and/or intermediate signals may be projected using a triaxial accelometer.

Abstract: A system is provided for tracking the three-dimensional position of an object within a three-dimensional region by triangulation techniques to generate signals corresponding to such three-dimensional positions. The signals may be used to drive a music synthesizer. Triangulation may be by the use of at least three spaced apart ultrasound emitters cooperating with ultrasound receivers located on a body moving in the three-dimensional region. The position of each ultrasound receiver is calculable by triangulation from data from ultrasound pulses received by the receiver from the emitters. A sound map may be made of the region so that similar signals may drive the synthesizer differently for different sub-regions.
