US Patent:

20020196626, Dec 26, 2002
Filed:

Jun 21, 2001
Appl. No.:

09/681893
Inventors:

Bernard Petrillo - Rye NY, US
Bruno Israel - Kinderhook NY, US
Theodore Joshua - Pemberton NJ, US
International Classification:

F21V001/00
US Classification:

362/286000, 362/386000, 362/276000
Abstract:

An array of photo detectors or a ground glass is employed in concert with a beam-forming reflector to generate a positional error(s) as the light source is displaced from a reference location in the vertical plane. The beam is formed by means of a small hole through the reflector on its optical axis. These error signals are interpreted visually or introduced into electronic servo loops to mechanically drive the lamp assembly to an on-axis reference location. Provision is made to move the reflector along the optical axis to achieve co alignment of the reflected image of the arc source with its direct image.

US Patent:

20040105277, Jun 3, 2004
Filed:

Dec 3, 2002
Appl. No.:

10/065945
Inventors:

Bernard Petrillo - Rye NY, US
Bruno Israel - Kinderhook NY, US
International Classification:

F21V008/00
US Classification:

362/551000, 362/554000, 362/183000
Abstract:

An array of optical fibers are circularly arranged in a horizontal plane to totally encompass an isotropic radiator. This configuration efficiently captures the radiated light and is amenable to a large family of radiators without the need for critical alignment between the radiator and the fiber optic array.

Filed:

Dec 4, 2002
Appl. No.:

10/065965
Inventors:

Bernard Petrillo - Rye NY, US
Bruno Israel - Kindkerhook NY, US
International Classification:

F16H055/18
F16H001/04
US Classification:

074/422000, 074/409000
Abstract:

An improved rack and pinion has been developed that eliminates backlash without using split gears. It is amenable to easy retrofitting of existing systems.

US Patent:

20050022731, Feb 3, 2005
Filed:

Jul 30, 2003
Appl. No.:

10/604569
Inventors:

Bernard Petrillo - Rye NY, US
Bruno Israel - Kinderhook NY, US
International Classification:

B05C005/00
US Classification:

118300000, 359391000
Abstract:

To increase the optical resolution, microscope users routinely employ high aperture lenses. The highest resolution is attained through the use of immersion lenses with associated immersion fluids. A non-interfering delivery system is herein described to accurately dispense a controlled amount of this fluid precisely at the proper interface location.

US Patent:

20060021569, Feb 2, 2006
Filed:

Sep 12, 2005
Appl. No.:

11/224358
Inventors:

Bernard Petrillo - Rye NY, US
Bruno Israel - Kinderhook NY, US
International Classification:

B05C 5/00
US Classification:

118300000
Abstract:

To achieve high resolution, microscope users routinely employ immersion optics with associated immersion fluids. A non-interfering delivery system dedicated for inverted microscopes is herein described that accurately dispenses (and removes) a controlled amount of these fluids precisely at the proper specimen location.

US Patent:

20060108502, May 25, 2006
Filed:

Jan 3, 2006
Appl. No.:

11/323924
Inventors:

Bernard Petrillo - Rye NY, US
Bruno Israel - Kinderhook NY, US
International Classification:

G01J 1/32
US Classification:

250205000
Abstract:

A control system has been designed that maintains the overall intensity of a microscope's viewed image at a constant level. The system is further enhanced to match the color character of the microscope illuminator to a user-established color reference for replication and comparison purposes. A comparison bridge utilizing this system is described that is fully balanced in intensity and color character.
