  • Tunable laser-based process monitoring apparatus
    Publication number: 20060152729
    Abstract: A chemical imaging and process monitoring device which utilizes a computer controlled tunable laser to provide light at discrete wavelengths in the near infrared band and a focal plane array to image or a single-point photo detector to detect the intensity of light reflected from a sample illuminated at various wavelengths of light. The device also provides light intensity reference detectors at the source and terminus of the light delivery pathway for normalizing the collected data and for detecting defects in the light delivery pathway.

  • Spectroscopic pharmacy verification and inspection system
    Publication number: 20050288906
    Abstract: An apparatus for verifying the identity, quality and/or quantity of each product unit, such as, for example, a dosage unit of a pharmaceutical dispensed into a container, which includes an analyzing device, such as a spectrometer, and a control device for controlling the analyzing device. The invention is integrated with background art automated counting and dispensing systems such that product units may be individually analyzed and verified prior to being placed into the container.
