Patent number: 9115867Abstract: The present invention provides an illuminator system comprising a dual reflector system and a linear light source. The dual reflector system comprises a primary and secondary generally cylindrical reflector, which collimate light from a linear light source in two planes. The linear light source may comprise many light emitting devices, and may emit light in a strobe or continuous fashion. The reflectors may be of many cylindrical shapes, and may include additional mirror segments to capture light otherwise not collimated. Further, the reflectors may be in various configurations of position and orientation with respect to one another, and may be adjustable in this respect. The system is more efficient than existing illuminators, is compact, all reflective (no color), lightweight, simple and inexpensive to manufacture. The system has applications to many fields including machine vision, surveillance, spectroscopic inspection of materials, and converting linear light sources into rectangular beam spot lights.Type: GrantFiled: October 19, 2010Date of Patent: August 25, 2015Assignee: MACDONALD, DETTWILER AND ASSOCIATES INC.Inventor: Dennis Gregoris

Patent number: 8515576Abstract: The present invention was developed by a neurosurgeon and seeks to mimic the results of primate neurological research which is indicative of a human's actual neurological control structures and logic. Specifically, the motor proprioceptive and tactile neurophysiology functioning of the surgeon's hands and internal hand control system from the muscular level through the intrafusal fiber system of the neural network is considered in creating the robot and method of operation of the present invention. Therefore, the surgery is not slowed down as in the art, because the surgeon is in conscious and subconscious natural agreement and harmonization with the robotically actuated surgical instruments based on neurological mimicking of the surgeon's behavior with the functioning of the robot. Therefore, the robot can enhance the surgeon's humanly limited senses while not introducing disruptive variables to the surgeon's naturally occurring operation of his neurophysiology.Type: GrantFiled: August 8, 2011Date of Patent: August 20, 2013Assignee: MacDonald, Dettwiler and Associates Ltd.Inventors: Kenneth L. Lipow, Dennis Gregoris

Publication number: 20080004632Abstract: A robot system for use in surgical procedures has two movable arms each carried on a wheeled base with each arm having a six of degrees of freedom of movement and an end effector which can be rolled about its axis and an actuator which can slide along the axis for operating different tools adapted to be supported by the effector. Each end effector including optical force sensors for detecting forces applied to the tool by engagement with the part of the patient. A microscope is located at a position for viewing the part of the patient. The position of the tool tip can be digitized relative to fiducial markers visible in an MRI experiment. The workstation and control system has a pair of hand-controllers simultaneously manipulated by an operator to control movement of a respective one or both of the arms. The image from the microscope is displayed on a monitor in 2D and stereoscopically on a microscope viewer. A second MRI display shows an image of the part of the patient the real-time location of the tool.Type: ApplicationFiled: April 16, 2007Publication date: January 3, 2008Inventors: Garnette Sutherland, Deon Louw, Paul McBeth, Tim Fielding, Dennis Gregoris
