DEVICE AND METHOD FOR MEASURING A QUANTITY OVER A SPATIAL REGION
First Claim
1. A measurement device comprising:
- a sensor;
a spatial subsystem for determining, at a time substantially simultaneous with a measurement of a quantity by said sensor, spatial information comprising one of a position of said device relative to a reference position, an orientation of said device relative to a reference orientation, and a combination thereof;
a power source;
a user interface;
a housing; and
a processing subsystem comprising a processor and memory;
wherein said processing subsystem is adapted to provide, based on a dataset comprising measurements of said quantity made by said sensor and said spatial information provided by said spatial subsystem, a determination of said quantity over a selected spatial region.

Abstract
The present invention enables the measurement and determination of a quantity over a selected spatial region by providing a device that incorporates a sensor for the measurement of the quantity and a spatial subsystem for determining the spatial information comprising a spatial position and/or orientation of the device when the measurement is made. A processing module integrated with the device operates on a dataset of multiple measurements correlated with spatial information and provides a determination of the quantity over the selected spatial range, either directly based on the measured data point and the spatial information or via a sensor fusion algorithm such as an interpolation algorithm. The results may be displayed on the device, for example, on a graphical display, or may be transmitted to a remote processor for subsequent processing and/or display.
