Abstract: An anatomy visualization device may include a display, an optical sensor, and processing circuitry. The processing circuitry may be configured to capture, via the optical sensor, body registration points on a body of an individual, receive external anatomical measurements of the body, apply the external anatomical measurements to a body shape model, and determine an organ placement prediction for the body based on the application of external anatomical measurements to the body shape model. The organ placement prediction may include organ position information, organ size information, and organ shape information for a plurality of organs. The processing circuitry may also align the organ placement prediction with the body registration points and render, on the display, the organ placement prediction in alignment with the body registration points as an augmented reality object on the body.

Abstract: A fast-rate thermoelectric device control system includes a fast-rate thermoelectric device, a sensor, and a controller. The fast-rate thermoelectric device includes a thermoelectric actuator array disposed on a wafer, and the thermoelectric actuator array includes a thin-film thermoelectric (TFTE) actuator that generates a heating and/or a cooling effect in response to an electrical current. The sensor is configured to measure a temperature associated with the heating or cooling effect and output a feedback signal indicative of the measured temperature. The controller is in communication with the fast-rate thermoelectric device and the sensor, and is configured to control the electrical current based on the feedback signal.

Abstract: A method of determining bone fragment navigation may include receiving pre-operative 2D image data of a reference bone structure and a bone fragment. The reference bone structure may include a first set of fiducial markers provided thereon, and the bone fragment may include a second set of fiducial markers provided thereon. The method may further include performing a 2D-3D registration between the pre-operative 2D image data and a 3D model of the reference bone structure and the bone fragment, after manual repositioning of the bone fragment, receiving second 2D image data, performing 2D-2D registration of the first set of fiducial markers and the second set of fiducial markers between the pre-operative 2D image data and the second 2D image data, and determining 3D movement of the bone fragment based at least in part on the 2D-2D registration.

Abstract: A prosthetic terminal device includes a wrist interface portion, a passive element and an active element. The passive element includes at least two finger-like projections extending from a base in a direction substantially away from the wrist interface portion. The passive element is fixed in relation to the wrist interface portion. The active element is configured to be positioned relative to the passive element and the wrist interface portion to achieve a plurality of grasp positions of the prosthetic terminal device based on one dimension of closure control of the active element in combination with a plurality of different fixable orientation positions of the active element. Each of the different fixable orientation positions is associated with at least one grasp position and at least one of the fixable orientation positions is associated with at least two grasp positions.
