Publication number: 20030052777Abstract: The present invention describes the use of a space-based Extremely Low Frequency (ELF) magnetic field detector in conjunction with ground-based network of ELF magnetic field detectors. In particular, a space based ELF detection system can be used to perform a wide area search and find precursor earthquake signals in both known and unknown earthquake zones, and a ground-based network of ELF detectors can be used to verify that the signals are indeed earthquake generated signals. The use of this invention will minimize cost and manpower necessary to effectuate an accurate and reliable earthquake detection system.Type: ApplicationFiled: December 14, 2001Publication date: March 20, 2003Inventor: Thomas E.

Patent number: 6530284Abstract: A plurality of sensing units are buried at suitable intervals in an area of ground or a snow accumulation section to be observed. Each of the sensing units includes a gyro-sensor for, when external force acts on it as a result of the displacement of the ground or the snow accumulation section, sensing impulsive acceleration from the magnitude and direction of the displacement and the inclination of the sensing unit itself, and a transmission section for transmitting the sense data by radio. A base station acquires the sense data transferred from the sensing units, processes the sense data for each measuring point in real time, determines the movement of the ground and/or the snow accumulation section, and judges a state of the ground and/or the snow accumulation section on the basis of the movement.Type: GrantFiled: June 28, 2000Date of Patent: March 11, 2003Assignees: Mitsui Bussan Plant & Project Corporation, Toshiba Engineering CorporationInventors: Eitarou Tambo, Takaaki Ikeda, Takashi Oogawara

Patent number: 6480115Abstract: A multiple hazard marker system consists of at least one multiple hazard marker, a deployment vehicle, a deployment surface and a deployment device for deploying the multiple hazard marker. The multiple hazard marker comprises a ground engaging portion, an upper portion and a central portion. The multiple hazard marker will remain erect when deployed and includes a visible marker for marking a position upon a field where deployed. The multiple hazard marker further has collapsible elements that expand upon deployment, a signaling device, a receiver for activating the signaling device and transmitter associated with the signaling device. The deployment device for deploying the multiple hazard marker collapses and retains the multiple hazard marker in the deployment device until a releasing mechanism releases the multiple hazard marker from the deployment device at deployment.Type: GrantFiled: July 9, 2001Date of Patent: November 12, 2002Inventor: Bahador Ghahramani

Patent number: 6462665Abstract: A method and apparatus of an alert system for notifying subscribers of weather or hazardous conditions. A weather-tracking source or service broadcasts weather or hazardous conditions across the nation to alert the general public of potentially dangerous climatic and hazardous conditions that may arise from time to time. A weather service provider receives the weather condition broadcasts from the weather-tracking source or service and transmits weather or hazardous condition signals to subscribers having an alert unit. The alert unit is a passive device capable of receiving and warning the subscribers of the weather or hazardous condition broadcasts.Type: GrantFiled: May 16, 2000Date of Patent: October 8, 2002Assignee: Wheelock, Inc.Inventors: Peter B.
