Patent number: 9423357Abstract: One embodiment relates to an oblique illuminator. The oblique illuminator includes a light source emitting a light beam, a first reflective surface, and a second reflective surface. The first reflective surface has a convex cylindrical shape with a projected parabolic profile along the non-powered direction which is configured to reflect the light beam from the light source and which defines a focal line. The second reflective surface has a concave cylindrical shape with a projected elliptical profile which is configured to reflect the light beam from the first reflective surface and which defines first and second focal lines. The focal line of the first reflective surface is coincident with the first focal line of the second reflective surface. The first and second focal lines of the second reflective surface may be a same line in which case the elliptical curvature is a projected spherical profile. Other embodiments, aspects and features are also disclosed.Type: GrantFiled: May 28, 2014Date of Patent: August 23, 2016Assignee: KLA-Tencor CorporationInventors: Shiyu Zhang, Charles N.

Patent number: 7654715Abstract: A system for illuminating a specimen are disclosed herein. In general, the system may include an illumination source configured to generate light with an uneven distribution at a pupil plane and field stop of the system, a lightpipe coupled for redistributing the light across the pupil plane and field stop, and at least one optical element configured to direct the redistributed light onto a specimen. The lightpipe may generally include a cone-shaped portion and a rectangular-shaped portion. The cone-shaped portion is configured for modifying an angular distribution of the generated light, so that the redistributed light is uniformly distributed across the pupil plane of the system. The rectangular-shaped portion is formed contiguous with the cone-shaped portion and configured for modifying a spatial distribution of the generated light, so that the redistributed light is uniformly distributed across a field stop of the system.Type: GrantFiled: August 9, 2007Date of Patent: February 2, 2010Assignee: KLA-Tencor Technologies CorporationInventors: Qibiao Chen, Charles N.

Patent number: 7313246Abstract: Eyewear comprises a microphone and a speaker. An eyewear neck strap couples the microphone and speaker to a wearer unit carried by the eyewear wearer. The wearer unit exchanges wireless signals with a base station. The base station is coupled to various devices such as surgical theater equipment, and/or to a telecommunication system, such as a telephone system. The eyewear enables the wearer to conduct hands-free communication such as telephone conversations and command and control operations, as well as to perform other hands-free tasks such as dictation. The wearer also receives data in audio form or as an image using a video display coupled with the eyewear.Type: GrantFiled: October 6, 2001Date of Patent: December 25, 2007Assignee: Stryker CorporationInventors: Eric C.

Patent number: 6729726Abstract: Eyewear for two-way communication comprises a speaker and a microphone. The speaker is supported by an earstem of the eyewear. In some embodiments the earstem is formed into a speaker support loop. The speaker is supported by the loop and held away from the wearer's external outer ear. Speaker position is adjustable in relation to the wearer's ear. An electrical cord couples the microphone and speakers to a wearer unit that includes a wireless transceiver. The electrical cord functions as a neck strap to support the eyewear when removed from the head.Type: GrantFiled: October 6, 2001Date of Patent: May 4, 2004Assignee: Stryker CorporationInventors: Eric C. Miller, Charles N. Wang, Erhan H. Gunday, Albert M. Juergens

In addition, maximum percentages of violet and/or blue light are transmitted. In some cases, the lens transmits a maximum percentage average intensity of red light while transmitting the minimum 95 percent average intensity of light in the brightness perception spectrum. The lens is incorporated in protective eyewear, especially into eyewear used by medical personnel.Type: GrantFiled: October 6, 2001Date of Patent: November 4, 2003Assignee: Stryker CorporationInventors: Charles N.
