Abstract: A method and system for analysis of a viscoelastic response in a deformable material. The system includes a light source configured to provide linearly polarized light and a polariscope configured to receive said linearly polarized light and to generate an image associated with a viscoelastic response of said deformable material. The system also includes a machine vision system configured to operate on the image to locate the response on the deformable material and to classify the response as one of a plurality of predefined types of responses. A display may then be provide that is configured to provide feedback of the location of the viscoelastic response and classification of the response to a user of said system.

Abstract: The present disclosure relates to a system for overlaying ultrasound imagery on a laparoscopic camera display. The system may include a laparoscope configured to capture a laparoscopic image of a surgical field and a laparoscopic ultrasound probe configured to capture an ultrasonic image of a structure in the surgical field. The system may further include a tracking system configured to detect a position and orientation of the laparoscope and a position and orientation of the laparoscopic ultrasound probe. The system may further include data associated with the laparoscope wherein the data indicates a distortion in the laparoscopic image. The system may further include a computer configured to receive the laparoscopic image, the ultrasonic image and the distortion data associated with the laparoscope.

Abstract: The present disclosure relates to a wearable workspace system which may include an input device and a head worn display coupled to a wearable computer. The input device may be configured to detect user input data wherein the user input data is provided by a user hands-free. The computer may be configured to: store an electronic technical manual, receive the detected user input data and generate an output based on the recognized user input data. The head worn display may be configured to display at least a portion of the electronic technical manual to the user while allowing the user to simultaneously maintain a view of a work piece. The display may be further configured to receive the output from the computer and to adjust the at least a portion of the electronic technical manual displayed to the user based on the output.

Abstract: A virtual reality system transposes a user's position and movement in real space to virtual space. The virtual reality system includes a locomotion interface that outputs signals indicative of a user's position in real space. The locomotion interface includes a pressure-sensing mat having a base layer, a plurality of pressure sensing elements formed over the base layer, and a top layer formed over the plurality of pressure-sensing elements, and a base around which the pressure sensing mat is disposed, the pressure-sensing mat being freely moveable about the base. The plurality of pressure sensing elements output a signal indicative of pressure applied to the top layer. A virtual reality processor uses the signals output by the locomotion interface to produce an output indicative of the user's position in the virtual space corresponding to the user's position and movement in the real space. A display uses the output from the virtual reality processor to produce an image of the virtual space.
