Abstract: The present invention is a multi-purpose portable imaging device. The device is small enough to be hand-held or wearable and has embedded on its surface at least one sensor. These sensors may be active or passive. Analog energy received from the sensors is converted into a digital format and sent to an advanced computer. The computer is constructed on parallel architecture platform. The computer has the capability of taking data from multiple sensors and providing sensor fusion features. The data is processed and displayed in a graphical format in real time which is viewed on the imaging device. A keypad for entering data and commands is available on the device. The device has the capability of using a removable cartridge embedded with read only memory modules containing application software for manipulating data from the sensors. The application cartridge provides the imaging device with its multi-purpose functionality.
