  • Position sensitive solid state detector with internal gain
    Patent number: 6998619
    Abstract: The present invention is a solid state detector that has internal gain and incorporates a special readout technique to determine the input position at which a detected signal originated without introducing any dead space to the active area of the device. In a preferred embodiment of the invention, the detector is a silicon avalanche photodiode that provides a two dimensional position sensitive readout for each event that is detected.

  • Method and apparatus for detecting, monitoring, and quantifying changes in a visual image over time
    Publication number: 20050105789
    Abstract: A method of quantifying measurements associated with a subject using a visual image of the subject includes acquiring digital representations of first and second images of the subject, determining difference information between the first and second images, and converting this information into physical, chemical, electrical, or electrochemical information concerning the subject. An apparatus for quantifying measurements associated with a subject using a visual image of the subject includes a digital camera and a computer. The camera acquires digital representations of first and second images of the subject. The computer is responsive to the digital representations and determines difference information between the first and second images. The difference information represents a change in a visual parameter between the first and second images. The computer converts the difference information into physical, chemical, electrical, or electrochemical information associated with the subject.
