Publication number: 20080278292Abstract: The present invention provides a solution to mistaken location calculations based on multipath effects. The present invention utilizes tags attached to objects that transmit signals at various power levels for reception by sensors stationed throughout a facility. Sensor readings at the various power levels are utilized to determine the location of the tagged object.Type: ApplicationFiled: May 7, 2008Publication date: November 13, 2008Applicant: Awarepoint CorporationInventors: Nicolas C. Nierenberg, Dyami Caliri

Patent number: 7443297Abstract: A wireless tracking system and method with a tag removal detection feature is disclosed herein. The system and method utilize a tag attached to an asset which includes a processor, a motion sensor (such as an accelerometer), a transceiver, a tag removal sensor and a power source having a limited supply of power. The tag removal sensor is an optical sensor which is activated only when the motion sensor detects motion. In this manner, the tag conserves power since the tag is typically only in motion ten percent of the day. If the tag is removed from the asset, the optical sensor confirms the removal and an alert is activated by the system.Type: GrantFiled: December 29, 2007Date of Patent: October 28, 2008Assignee: Awarepoint CorporationInventors: Robert Baranowski, Dyami Caliri, Derek Smith

Publication number: 20080055158Abstract: Techniques for accurate position location and tracking suitable for a wide range of facilities in variable environments are disclosed. In one aspect, a system for position location comprises a plurality of sensors (e.g. a network monitor, an environment sensor) for generating measurements of a plurality of sources, a plurality of objects or tags, each object generating measurements of the plurality of sources, and a processor for receiving the measurements and generating a position location for one or more objects in accordance with the received measurements. In another aspect, a position engine comprises a mapped space of a physical environment, and a processor for updating the mapped space in response to received measurements. The position engine may receive second measurements from an object within the physical environment, and generate a position location estimate for the object from the received second measurements and the mapped space.Type: ApplicationFiled: October 26, 2007Publication date: March 6, 2008Applicant: Awarepoint CorporationInventors: Derek Smith, James Adams, Nicolas Nierenberg, Joseph Baker

Publication number: 20080012767Abstract: A system (50) and method (300) for providing multipath error mitigation for real-time wireless tracking of an object (100) is disclosed herein. A plurality of sensor readings are obtained from a tag (60) attached to an object (100) within an indoor facility (70). A plurality of reading sets are generated and sorted by zones. A zone with the highest average reading is preferably selected and the location of the object (100) is calculated based on the selected zone readings. In this manner, faulty position readings are eliminated from the location calculation thereby allowing for more accurate tracking of the object (100) within the indoor facility (70).Type: ApplicationFiled: February 7, 2007Publication date: January 17, 2008Applicant: AWAREPOINT CORPORATIONInventors: Dyami Caliri, Derek Smith
