  • Light beam generation, and focusing and redirecting device
    Patent number: 6951411
    Abstract: An improved light beam generation and focusing device (15, 50) has a light source (16, 51) constructed and arranged to emit at least one beam of light (20), and a lens assembly (17, 19, 56) constructed and arranged to focus the at least one beam of light on a surface plane. The device is constructed and arranged to sequentially direct the at least one beam of light to at least two spaced locations (21, 21?) on the surface plane. The lens assembly comprises a collimating lens (17), and a spaced focusing lens (19).

  • Dual function assay device
    Patent number: 6704587
    Abstract: A system and method for detecting substances such as glucose in tissue. The system comprises an assay device and an optical apparatus. The assay device comprises a reactive region that is responsive to at least one substance in fluid to be collected from the tissue when the fluid is in contact with the reactive region, and which reactive region is also responsive to a first type of optical energy suitable to heat up and transfer heat by conduction to the tissue to ablate the tissue and form at least one opening in the tissue from which fluid is collected. The optical apparatus has an activation head to which the assay device is attached, and a first optical energy source that outputs a first type of optical energy. An optical detecting device is included in the optical apparatus that measures a characteristic of the at least one substance from the response of the reactive region when the reactive region is in contact with the at least one substance.
