Patent number: 9165114Abstract: A calibration/surgical tool includes an electromagnetic sensor array of two or more electromagnetic sensors in a known geometrical configuration. Electromagnetic tracking errors are characterized by a mapping of pre-operative absolute and relative errors based on a movement of a calibrated calibration/surgical tool through a pre-operative electromagnetic field. Using statistical mapping, a desired absolute error field is measured either in the clinic as the part of daily quality control checks, or before the patient comes in or in vivo. A resulting error field may be displayed to the physician to provide clear visual feedback about measurement confidence or reliability of localization estimates of the absolute errors in electromagnetic tracking.Type: GrantFiled: February 21, 2011Date of Patent: October 20, 2015Assignee: Koninklijke Philips N.V.Inventors: Ameet Kumar Jain, Mohammad Babak Matinfar, Raymond Chan, Vijay Parthasarthy, Douglas A.

Patent number: 7933007Abstract: An electro-magnetic tracking system includes a system controller having a sensor interface, a generator, and a positioning and angular orientation configuration. The generator is responsive to the system controller for generating an electro-magnetic field that includes a tracking volume of highest accuracy. The highest accuracy corresponds to an accuracy of the sensor interface and system controller to detect a sensor physically located within the tracking volume versus a lesser accuracy of the sensor interface and system controller to detect the sensor if the sensor is located outside of the tracking volume. The positioning and angular orientation configuration is coupled to the field generator for visibly optimizing (i) a positioning and/or (ii) an angular orientation of the electro-magnetic field generator such that the tracking volume lies within a centroid of a physical volume of interest, thereby enabling a detection of a sensor within the tracking volume with a highest accuracy.Type: GrantFiled: December 8, 2006Date of Patent: April 26, 2011Assignee: Koninklijke Philips Electronics N.V.Inventors: Douglas Stanton, Jochen Kruecker

Patent number: 6982683Abstract: A head-mounted projection display system is characterized by a pair of head-mounted low-power image projectors mounted adjacent the eyes of the viewer, and aimed to project in a direction along the line of sight of the viewer toward a high-gain, retro-reflective screen. Stereoscopic viewing is enabled by projecting separate images to the right and left projectors. The retro-reflectivity of the screen ensures that the right and left images will be returned to the right and left eye, respectively.Type: GrantFiled: March 18, 2003Date of Patent: January 3, 2006Assignee: Koninklijke Philips Electronics N.V.Inventor: Douglas A.

Patent number: 6905216Abstract: The present invention relates to a method of generating an image having a desired brightness, which image is generated by means of a device provided with at least one light source, at least one electro-optical light modulation panel and at least one light-control device. The light from the light source is converted into an image having a desired brightness via at least the electro-optical light modulation panel and the light-control device. The image to be projected is analyzed in a regulator, whereafter the electro-optical light modulation panel and the light-control device are driven, while a too bright image is generated by means of the electro-optical light modulation panel, which image is converted by means of the light-control device into an image having a desired brightness and a desired contrast.Type: GrantFiled: August 18, 2003Date of Patent: June 14, 2005Assignee: Koninklijke Philips Electronics N.V.Inventors: Douglas A.

Patent number: 6690432Abstract: A prism is mounted onto a motor without regard to its rotation angle relative to the motor index. Its position is electronically set later after construction of the optical path. A motor controller is used to control the rotation of the prism. This motor controller keeps the prism spinning at a constant velocity and positions the prism phase (rotation angle versus time). A variable offset is used to position the absolute prism rotation as a function of time. The phase may be advanced or delayed by an operator during set up. Each prism has its own phase. The phase of each prism in the system is set so that the illumination pattern correctly matches the video addressing of the panel. This is a one time set up during construction. The correct positions are set, and stored in non-volatile memory for life.Type: GrantFiled: April 12, 2001Date of Patent: February 10, 2004Assignee: Koninklijke Philips Electronics N.V.Inventors: Peter J.
