  • Systems and methods to analyze multiplexed bead-based assays using backscattered light
    Patent number: 7764361
    Abstract: This invention relates to a system and method related to an epifluorescence microscope based optical system equipped with a tunable filter to localize microspheres in bead-based assays based on a back-scattered light (also known as reflected light) image. A common optical path for reflected and emitted luminescence in conjunction with a tunable filter negates the requirement of an additional sensor employed in existing technologies for localizing microspheres based on light scatter measurements.

  • Constant speed sample collection or injection system
    Publication number: 20020072719
    Abstract: A constant speed fluid sample collection system for use with a catheter, needle, or the like in communication with a patient's vein is useful to extract a blood sample. The system uses a constant force system to not disrupt the components of the fluid, such as platelets found in blood. The system includes a syringe device and moves a plunger at a constant velocity. The device includes a housing, a piston rod movably mounted within the housing, and a brake mechanism for controlling the movement of the piston with respect to a syringe positioned within the housing. The plunger retracts into the drive device as it is being withdrawn.
