Publication number: 20060000613Abstract: Disclosed is a device and method for externally perforating a well-bore casing. The perforating apparatus is attached to the outside of the casing itself and is conveyed along with the casing when it is inserted into the well bore. The perforation is accomplished using two groups of charges which are contained in protective pressure chambers which are arranged radially around the outside of the wellbore casing. The pressure chambers form longitudinally extending ribs which conveniently serve to center the casing within the well bore. One group of charges is aimed inward in order to perforate the casing. A second group is aimed outward in order to perforate the formation. In an alternative embodiment, only one group of bi-directional charges is provided.Type: ApplicationFiled: July 29, 2004Publication date: January 5, 2006Inventors: Matthew Bell, Eugene Murphy, Edward Cernocky, Christopher Burres, Aron Ekelund, Allen Lindfors

Patent number: 6837584Abstract: A method and apparatus for producing an apparent increase in display brightness in an RPTV engine without an actual increase in total light output. Light is generated with an illumination source and optically processed to produce a light beam of rectangular format. The light beam is formed intentionally to have an intensity that is non-uniform, varying from a peak intensity at a center of the beam to a minimum intensity at a periphery of the beam. The optical processing step can include varying the intensity to selectively produce an illumination profile that decreases by at least about 30% to 70% from the peak intensity to the minimum intensity. The optical processing step can further include projecting the light beam through an integrator that is configured to produce an illumination profile that is at least partially controlled by a length of the integrator. The integrator can be configured so that a decrease in length will result in reduced uniformity.Type: GrantFiled: May 17, 2002Date of Patent: January 4, 2005Assignee: Thomson Licensing S.A.Inventors: Valter Drazic, Eugene Murphy O'Donnell

Publication number: 20030132894Abstract: The invention concerns an illumination source for a LCOS projection system. The illumination source is a cathode ray tube (CRT) that excites an array of phosphor based resonant microcavities. By selecting a uniform phosphor type for use in the array of resonant microcavities, the CRT can be designed to exclusively generate light of a selected color. The resonant microcavities can be arranged so that the light is projected through an LCOS device to produce an image. A projector lens can also be provided for magnifying and focusing the image for projection on a screen.Type: ApplicationFiled: January 14, 2002Publication date: July 17, 2003Inventors: Eugene Murphy O'Donnell, Estill Thone Hall
