  • Patent number: 7890158
    Abstract: Methods and apparatuses for performing biometric determinations using optical spectroscopy of tissue. The biometric determinations that are disclosed include determination or verifications of identity, estimation of age, estimation of sex, determination of sample liveness and sample authenticity. The apparatuses disclosed are based upon discrete light sources such as light emitting diodes, laser diodes, vertical cavity surface emitting lasers, and broadband sources with multiple narrow-band optical filters. The multiple light sources are encoded in a manner that the tissue response for each source can be efficiently measured. The light sources are spaced at multiple distances from a detector to contribute differing information to the biometric determination task as do light sources with different wavelength characteristics.

  • Patent number: 7884390
    Abstract: A vertically conducting semiconductor device includes a semiconductor substrate having a topside surface and a backside surface. The semiconductor substrate serves as a terminal of the vertically conducting device for biasing the vertically conducting device during operation. An epitaxial layer extends over the topside surface of the semiconductor substrate but terminates prior to reaching an edge of the semiconductor substrate so as to form a recessed region along a periphery of the semiconductor substrate. An interconnect layer extends into the recessed region but terminates prior to reaching an edge of the semiconductor substrate. The interconnect layer electrically contacts the topside surface of the semiconductor substrate in the recessed region to thereby provide a topside contact to the semiconductor substrate.

  • Patent number: 7883471
    Abstract: Minimally invasive methods, systems and devices are provided for qualitatively and quantitatively assessing collateral ventilation in the lungs. In particular, collateral ventilation of a target compartment within a lung of a patient is assessed by advancement of a catheter through the tracheobronchial tree to a feeding bronchus of the target compartment. The feeding bronchus is occluded by the catheter and a variety of measurements are taken with the use of the catheter in a manner which is of low risk to the patient. Examples of such measurements include but are not limited to flow rate, volume and pressure. These measurements are used to determine the presence of collateral ventilation and to quantify such collateral ventilation.

  • Patent number: 7883206
    Abstract: Embodiments of the present invention relate to a multifocal lens having a mostly spherical power region and a progressive optical power region. Embodiments of the present invention provide for the proper alignment and positioning of each of these regions, the amount of optical power provided by each of the regions, the optical design of the progressive optical power region, and the size and shape of each of the regions. The combination of these design parameters allows for an optical design having less unwanted astigmatism and distortion as well as both a wider channel width and a shorter channel length compared to conventional PALs. Embodiments of the present invention may also provide a new, inventive far-intermediate distance zone and may further provide for increased vertical stability of vision within a zone of the lens.
