Navigation system for cardiac therapies
TL;DR: In this paper, an image guided catheter navigation system for navigating a region of a patient includes an imaging device, a tracking device, and a controller, as well as a display that displays the image of the region with the catheter superimposed onto the image at the current location.
Patent
Method and apparatus for surgical navigation
TL;DR: In this article, a non-invasive dynamic reference frame and/or fiducial marker, sensor tipped instruments, and isolator circuits are used for navigating a region of a patient.
Patent
Computer-aided surgery apparatus
TL;DR: A computer-aided surgical device for aiding a surgeon in positioning a surgical instrument (power or manual) when performing surgery on unexposed and exposed portions of a patient is described in this article.
Patent
System for indicating the position of a surgical probe within a head on an image of the head
TL;DR: In this article, a system for determining a position of a probe relative to an object such as a head of a body of a patient is presented. But the system is limited to the case where the head does not appear in the scan images, and the position of the forehead contour is determined with an optical scanner and a ring.
Patent
Method and apparatus for performing stereotactic surgery
TL;DR: In this paper, a stereotactic head frame is coupled to the patient and is used to assist in guiding the instrument to the target, while the imaging device captures image data of the patient.

Method and apparatus for electro optically determining the dimension, location and attitude of objects
TL;DR: In this paper, the authors describe a method and apparatus for optically determining the dimension of part surfaces, such as gear teeth and turbine blades, using optical triangulation based coordinate measurement machines.
Patent
Distance measuring apparatus
TL;DR: In this paper, a differentiation circuit was added to an output terminal of a photoelectric conversion element to prevent the back scattering light power from exceeding the received light power, which was used to prevent erroneous distance measurement.
Patent
Device for determining distance of area illuminated by pulsed laser
TL;DR: In this paper, the time interval between the arrivals of a direct laser pulse and of a reflection of the same pulse from the target is measured along with the angle included between the two directions of incidence.
Patent
Photographing lens system with focus informing means
TL;DR: In this article, a photographing lens which is mounted on a camera in an interchangeable manner is provided with a focus-informing means, which informs the photographer of focussings of the lens during manual focussing operation thereof by buzzer or by small lamp.
