  • Optical Measurements while in Motion
    Publication number: 20170319142
    Abstract: This invention provides improved optical measurements while in motion by collecting a force signal that measures how hard the optical device is pressing on the body. The force signal is used by a noise-canceling algorithm to reduce motion artifacts from the desired optical signal.

  • Optimized gas cell
    Patent number: 7749446
    Abstract: A gas cell used in analytical instrumentation directs the flow of the sample gas to the center of the cell, allowing the outlets to be place on the ends, very near the windows and or mirrors of the cell. This reduces contamination by moving the inlet as far from the ends as possible and improves flow by having the outlets close to the ends of the cell.

  • Sample rotator with fixed sampling point
    Patent number: 7070319
    Abstract: A device for holding and rotating cylindrical sample containers for use in analytical instrumentation. The device maintains the surface of material in the container at a constant location during rotation by using a series of fixed contact points. The drive wheel is tension to secure the sample container to the fixed supports and to automatically accommodate different size containers without adjustment.
