    摘要: A method and system for ultrasonic locationing using time difference of arrival measurements includes an ultrasonic receiver including three microphones each disposed on a periphery of a housing and a fourth centrally-positioned microphone. A controller establishes only time difference of arrival measurements of an ultrasonic signal at each microphone, assumes an arbitrary flight time for the signal in order to obtain three flight distances of the signal at each of the three microphones, calculates an intersection point of three spheres having radii equal to the three flight distances, calculates a distance from the intersection point to the central microphone, subtracts the distance from a sum of the arbitrary flight time plus the time difference of arrival measurement for the central microphone to establish an test error, and searches different arbitrary flight times along a straight line through the central microphone and intersection point until the test error is less than a threshold, indicating an actual location of the emitter.

    摘要: An apparatus is described that can monitor the sounds and voices of infants and children in a house by judicially placing nodes in key locations of the home. The network has intelligence and uses voice recognition to enable, disable, reroute, or alter the network. The network uses voice recognition to follow a child from node to node, monitors the children according to activity and uses memory to delay the voices so the adult can hear the individual conversations. An adult that has been assigned privilege can disable all nodes from any node in the network. Another apparatus can locate an individual by voice recognition or sounds they emit including walking, breathing and even a heartbeat. The sound is detected at several microphones that have a specific positional relationship to a room or an enclosement. Triangulations of the time differences of the audio signal detected by the microphones are used to determine the location or position of the audio source in the room. This information can be used to provide an improved audio delivery system to the individual.

A method for estimating location information associated with a supersonic projectile propelled from a source includes recording sound at a first location using a single microphone during travel of the supersonic projectile to produce an acoustic recording. The method further includes estimating a miss distance between the first location and a trajectory of the projectile based on the shockwave length. Locating a projectile source includes concurrently recording sound at multiple locations and generating data sets associated with the locations, each of the plurality of data sets including a miss distance, a range, a time of arrival of a muzzle blast from the source, and a time of arrival of a shockwave produced by the projectile. Additionally, the method includes calculating an approximate location of the source at each of the locations based on the data sets.
