  • Publication number: 20190083027
    Abstract: A device for measuring spinal stiffness comprises a frame-work supporting a roller that is rolled over the surface of the back. The device creates and records a trajectory across a subject, using a control board and the roller, and moves the roller along the trajectory while applying a force to the subject using the roller and records displacement of the object in the direction of the force. A stiffness map is created using displacement as a function of force. Motors may be used to move the roller through three axes.

  • Publication number: 20180368883
    Abstract: A hand-held device for assisted steering of a percutaneously inserted needle comprises a handle, an actuation unit, and a haptic feedback unit. A computer-implemented system calculates a needle shape and position based on one or a combination of analysis of ultrasound images and determination of needle insertion parameters based on electronic signals generated by a sensor unit. The system calculates a correction to a needle insertion parameter to achieve a target needle trajectory, including a correction to a needle axial rotation. The system activates the actuation unit to rotate the needle in accordance with the correction to the needle axial rotation, and activates to the haptic feedback unit to vibrate the handle in a vibration pattern determined by a rules database depending on one or a combination of the calculated needle shape, the calculated needle position, and the correction to the needle insertion parameter.

  • Patent number: 10155797
    Abstract: The invention provides a binding-induced DNA nanomachine that can be activated by proteins and nucleic acids. This new type of nanomachine hamesses specific target binding to trigger assembly of separate DNA components that are otherwise unable to spontaneously assemble. Three-dimensional DNA tracks of high density are constructed on gold nanoparticles functionalized with hundreds of single-stranded oligonucleotides and tens of an affinity ligand. A DNA swing arm, free in solution, can be linked to a second affinity ligand. Binding of a target molecule to the two ligands brings the swing arm to AuNP and initiates autonomous, stepwise movement of the swing arm around the AuNP surface. The movement of the swing arm generates hundreds of oligonucleotides in response to a single binding event. The new nanomachines have several unique and advantageous features over DNA nanomachines that rely on DNA self-assembly.

  • Patent number: 10019809
    Abstract: An underwater camera system includes a projector operable to project a pattern of electromagnetic radiation toward a target object. The electromagnetic radiation includes at least three different wavelengths. A sensor directed toward the target object receives reflected electromagnetic radiation from the target object and stores corresponding image data received from the sensor. One or more processors process the image data to compute a refractive normal according to a wavelength dispersion represented by differences in the image data, and to compute an interface distance corresponding to a distance from a center point of the sensor to a first refractive interface nearest the sensor according to the refractive normal. The processors generate a 3D representation of the target object by back projecting each pixel of the image data at the first, second, and third wavelengths in order to determine an object point location according to the refractive normal and interface distance.
