Publication number: 20170010343Abstract: This invention provides a system and methods for tracking the positions and behaviors of moving objects such as animals. In one embodiment, the system comprises one or more tracking unit, one or more base nodes, one or more remote data hubs, and one or more remote processor with display. Each tracking unit (e.g. attached or inserted into the tracked animals) could transmit acoustic signal with a unique signature. The base nodes, after time stamping the received signals, relate the signals to the remote processors where the signals will be processed and the 3-dimensional spatial coordinates of the tracking units, and hence the animals, can be identified. Further processing of the positional information would reflect the activities and behaviors of each animal. Additional sensors included in the tracking unit provide further information about the states of the animals such as temperature, heart rate or blood pressure etc.Type: ApplicationFiled: September 12, 2016Publication date: January 12, 2017Inventors: Chi Shing CHAN, Aijun CAO

Patent number: 8781851Abstract: A dynamic claims adjudication system is provided that implements a dynamic claims adjudication process to provide flexible determination of the adjudication rule set to be used to adjudicate a claim for a particular prescription drug regardless of the mandates of the formulary and the rigidity of the tier into which the drug is placed on the formulary. The claims adjudication system and corresponding methods dynamically determine the adjudication rule set to be used to adjudicate a claim based on an analysis of criteria and identification of a tier changing criteria. Accordingly, the rigidity of conventional formulary based claims adjudication is eliminated in favor of dynamic and flexible real time claims adjudication.Type: GrantFiled: October 27, 2010Date of Patent: July 15, 2014Assignee: Medimpact Healthcare Systems, Inc.Inventors: Lori L. Anderson, Mai Ly Thi Hoang, Chi Shing Chan, Jose Eli J. Golez, Jr.
