Abstract: A method of enhancing the safety of a region includes defining a set of rules for the region. Collecting field data from a plurality of mobile stations movable throughout the region. The field data includes information relating to the relative movement of the mobile stations. Comparing the collected field data to the set of rules to identify one or more areas of potential risk within the region.

Abstract: A linear regression equation, ?1=?(?×h)+?, is obtained based on a depth h to a water zone of a predetermined water temperature, respective densities ?1 and ?2 of upper and lower layers above and below the water zone, and an absolute dynamic topography ?1 obtained based on data measured by satellite (?=(?2??1)/?2). Further, h? (depth of the water zone of the predetermined water temperature at each of a large number of spots) is determined according to this equation, ?2=?(??×h?)+?, based on ?? for each of the large number of spots calculated based on historical data, an absolute dynamic topography ?2 at each of the large number of spots based on data measured by satellite, and the values ? and ?.

Abstract: A combined statistical-deterministic approach to methods and systems for assessing risk associated with natural disasters, in particular, hurricane wind risk. One example of a method of predicting wind speed distribution within a predetermined distance from a point of interest includes steps of statistically synthesizing a large plurality of wind storm tracks that pass within a predetermined radius of the point of interest, running a deterministic simulation of wind intensity along each one of the large plurality of wind storm tracks to produce an output representative of wind speed distribution along each track, and using the output to estimate an overall wind speed probability distribution from a combination of the wind speed distributions along each track within the predetermined distance from the point of interest.

Abstract: It is possible to easily perform the spatial simulation for a large area. Provided is a computer-readable medium recorded with a spatial simulation program for controlling a computer to execute procedures for calculating a time-based change of a variable in a plurality of numerical grids to reproduce on a computer a time-based change of a phenomenon represented by the variable in a space represented by the plurality of numerical grids, the spatial simulation program including the procedures of: defining a sub domain composed of the plurality of numerical grids (201); setting a forcing condition for the sub domain (204); detecting the sub domain including the numerical grid in which the variable changes with time; detecting the sub domain including the numerical grid in which the variable referred to for calculating the time-based change is positioned (205); and updating variables in the numerical grids constituting the detected sub domain (208).

Abstract: An air monitoring system is disclosed having an air monitoring unit with at least one sensor for measuring data of an air quality parameter and a computer for storing the air quality parameter data received from the sensor. The air monitoring unit may use an installed or a portable system, or a combination of both, for measuring the air quality parameters of interest. A remote data center may be provided, and the data may be uploaded to the data center from the unit by a communications media such as the Internet. Information or instructions may also be downloaded from the data center to the unit via the communications media for controlling or modifying the function of the unit. An expert system may be provided with the air monitoring system for controlling the unit. The information or instructions downloaded to the unit may be generated by the expert system.

Abstract: A scheme for providing environmental information to users is disclosed. In this scheme, environmental information is measured automatically by each of a plurality of environment sensors arranged at a plurality of regions, and the environmental information measured by each environment sensor is collected automatically to a base device, and stored at the base device. Then, the environmental information is processed at the base device according to a user information of an individual user, and processed environmental information is provided from the base device to the individual user through a network connecting the users and the base device.

Abstract: A novel basic allergen/particulate data collection device and a novel multi-function personal air quality management device are disclosed. Both devices include sensor sub-assembly detecting and reporting on allergen/particulate data (preferably, for allergen/particulate with sizes smaller than 5 micron) for an indoor location (where the asthma patient is situated). Both devices are communication enabled to allow the allergen/particulate data to be provided to an air/asthma advice server, to generate air/asthma advice for an asthma patient, taking into consideration the allergen/particulate data as well as air quality data for a surrounding outdoor area of the indoor location. In one embodiment of the basic device, the communication interface is tailored for “harsh environment” local area networking.

In one embodiment of the basic device, the communication interface is tailored for “harsh environment” local area networking. When combined with its streamlined functionality, the device is particularly suitable (especially in terms of economics) for multiple deployment (along with a “base station”), such as in the case of an home application.

Abstract: A novel air/asthma advice method and apparatus for providing air/asthma advice to an asthma patient, taking into consideration indoor allergen as well as outdoor air quality conditions, is disclosed. Allergen data (preferably for allergen with sizes smaller than 5 micron) for an indoor location (where the asthma patient is situated) are collected, and provided to a geographically removed air/asthma advice server. The server, in turn, retrieves air quality data for a surrounding outdoor area of the indoor location (from either a private or an independent source), and generates an allergen advice response for the asthma patient. The air/asthma advice is generated based at least in part on the received allergen data and the retrieved air quality data. The air/asthma advice may be delivered to the asthma patient in any one of a number of forms (a beeping alert, a pager, fax, email or voice message, and so forth). Various other alterations and modifications under different embodiments are also disclosed.
