Abstract: Systems and methods are described for estimating a state of a process and an input to the process using a sensor network. Each sensor node in the sensor network is directly to one or more adjacent sensor nodes and indirectly coupled to the remaining sensor nodes through the one or more adjacent sensor nodes. Each sensor node iteratively calculates a new estimated state based on estimations of the state and the input to the process calculated by the sensor node in a previous iteration. The new estimated state is then adjusted based on a difference between a predicted and actual output of a sensor and is further adjusted based on differences between a previous estimated state calculated by the sensor node and estimated states calculated by adjacent sensor nodes.

Abstract: A system for monitoring evacuation of personnel from an offshore platform or ship uses personal identification transmitters worn by the crew and passengers, where each of the transmitters has been assigned unique identification parameters. The personal identification transmitters transit a signal that is picked up by a lifeboat-mounted transducer, which acknowledges presence of the wearer of the personal identification transmitter once the persons enters the lifeboat. The signal from the transducer is transmitted, via satellite to a computing machine, which generates a report acknowledging presence of each person on board the lifeboat and comparing the report to a list of persons who had been listed in the personnel-on-board master report. The remote management control centers allow management to issue commands to abandon ship once all persons have been accounted for.

Abstract: The present invention relates to a system and method for simultaneously using and configuring one or more disposable transmitters. The system includes at least one single or multiple use disposable transmitter, a central station, and a receiver module. The transmitter is connected to a patient to gather and measure biomedical information. The transmitter transmits the biomedical information through the receiver module to the central station for processing, storage and display. Prior to use, each transmitter must be configured to work with the central station and the receiver module. This allows the users to configure the disposable transmitters relatively quickly and easily without needing advanced technical information. The inventive configuration also enables the operator to map a location on a monitor in the central station to a specific disposable transmitter and ultimately to a specific patient or location in the coverage area that is covered by the system.

Abstract: A radio communications network for transmitting data from a plurality of remote stations to a central station is provided. This system is particularly proposed for automatic meter reading systems in which the remote stations are located at utility meters. The system includes an array of receiving stations arranged relative to the remote stations so that the messages from each remote station can be received by at least two and preferably four of the receiving stations providing a high level of duplication of messages. The remote stations transmit utility usage information obtained from a previous time period at a random time subsequent to the time period so that message collisions can occur. High level of duplication provided by the increased number of receiving stations reduces the message loss. A quiet period during which the remote stations are prevented from transmitting can be used for communication between the receiving stations and the central station.
