  • Patent number: 9655545
    Abstract: An apparatus and method for measuring mechanical properties of tissue has a stereo optical surgical microscope with at least one objective lens and at least two digital cameras such that paired images obtained from the digital cameras form stereo pairs, and a digital image processing system adapted to determine surface topography of tissue from the stereo pairs of images and a resulting surface displacement map as a result from indentation. The apparatus has an one indenter; and mechanical modeling routines stored in memory of the image processing system, the mechanical modeling routines capable of constructing computer models of mechanical properties of tissue, and fitting parameters of the computer model to observed surface displacement maps generated by coregistering surface topography of tissue with and without the indenter positioned on the tissue. In an embodiment, fitted parameters of the computer model are displayed and used to adjust a surgical plan.

  • Patent number: 9631018
    Abstract: The present invention relates to a novel regulatory T cell protein. This protein, designated PD-L3 OR VISTA resembles members of the PD-L1 family, identified a novel and structurally-distinct, Ig-superfamily inhibitory ligand, whose extracellular domain bears homology to the B7 family ligand PD-L1. This molecule is designated as PD-L3 OR VISTA or V-domain Immunoglobulin Suppressor of T cell Activation (VISTA). Expression of VISTA is primarily within the hematopoietic compartment and is highly regulated on myeloid APCs and T cells. Therapeutic intervention of the VISTA inhibitory pathway represents a novel approach to modulate T cell-mediated immunity for the treatment of a wide variety of cancers, e.g., ovarian, bladder cancer and melanomas. Also, VISTA proteins, especially multimeric VISTA proteins and antibodies may be used to suppress T cell immunity in autoimmune disease, allergy, infection and inflammatory conditions, e.g. multiple sclerosis and arthritic conditions such as RA.

  • Patent number: 9595187
    Abstract: A wearable master electronic device (Amulet) has a processor with memory, the processor coupled to a body-area network (BAN) radio and uplink radio. The device has firmware for BAN communications with wearable nodes to receive data, and in an embodiment, send configuration data. The device has firmware for using the uplink radio to download apps and configurations, and upload data to a server. An embodiment has accelerometers in Amulet and wearable node, and firmware for using accelerometer readings to determine if node and Amulet are worn by the same subject. Other embodiments use pulse sensors or microphones in the Amulet and node to both identify a subject and verify the Amulet and node are worn by the same subject. Another embodiment uses a bioimpedance sensor to identify the subject. The wearable node may be an insulin pump, chemotherapy pump, TENS unit, cardiac monitor, or other device.

  • Patent number: 9532029
    Abstract: Systems and methods generate a 3D model of a surface of an object immersed in a transparent liquid within a stationary cylindrical transparent tank. First and second laser line projectors and a camera are rotated around a central axis of the cylindrical tank. The first and second laser line projectors each generate a laser line perpendicular to a plane or rotation and aligned with the center of rotation. The camera images the object. An image from the camera is captured at each of several angular positions of the camera relative to a reference position of the stationary cylindrical tank. The captured images are processed to determine, for each laser line within each image, a plurality of 3D positions where the laser line is incident upon a surface of the object. In embodiments, images are corrected with ray tracing or image warping and registration functions.
