Filed:

Jun 6, 2003

Appl. No.:

10/456055

Inventors:

Christopher Rush - Forestville CA, US

International Classification:

G02B 6/00
G01J 1/04

US Classification:

25022711, 25022729, 25055938, 385 12, 356 731

Abstract:

An optical non-contact measuring probe for measuring small changes in distance to a target comprises a laser diode () coupled to a projecting fiber (), a receiving fiber () spaced a fixed distance from the projecting fiber, and a linear array () spaced a fixed distance from the emitting face () of the receiving fiber. Light is projected from the projecting fiber to a small area on the target. Light rays reflected from the target are collected by the receiving fiber at an angle and are carried by the receiving fiber by total internal reflection through the emitting face to the linear array where it is detected as a circle having a diameter φD. The distance from the probe to the target can be measured as inversely function of the diameter φD.

US Classification:

356609

Abstract:

A displacement measurement sensor using the confocal principle with an optical fiber for measuring small changes in distance to a specular target surface comprises a monochromatic light source such as a laser diode coupled to a multimode optical fiber. The fiber functions as both a transmitter, receiver of light ray angle information. An objective lens possessing spherical aberration separates the monochromatic light at different focal distances according to the magnitude of angular deviation from the optical axis. Each distance of the target surface from the objective lens will select specific angular rays able to retrace the path through the objective lens and fiber. Each angle then will correspond to specific distance. Angular information is preserved as the light path is traced back through the fiber and the angle measurement is determined by registering the light impinging on a light sensitive electronic detector array

Abstract:

A displacement measurement sensor using the confocal principle for measuring small changes in distance to a specular target surface comprises a monochromatic light source such as a laser diode an aperture, an objective lens system possessing spherical aberration that separates the monochromatic light at different focal distances according to the magnitude of angular deviation from the optical axis. Each distance of the target surface from the objective lens will select specific angular rays able to retrace the path through the objective lens and aperture. Each angle then will correspond to specific distance. The angle measurement is determined by detecting the light impinging on a light sensitive electronic detector array

Appl. No.:

12/829790

Inventors:

Christopher Rush - Forestville CA, US

International Classification:

H01L 31/0232

US Classification:

136256

Abstract:

The invention discloses a non-imaging reflecting surface optimized for concentrating solar energy onto a high efficiency solar cell. It provides for accurate mapping of solar radiation from the reflector to the cell. Additionally it provides for using only that portion of the surface that participates in the radiation transfer and it creates substantially uniform radiation intensity on the cell surface. The uniformity applies to both the spectral and the intensity distribution of the radiation on the cell. The reflecting surface is an off-axis parabolic surface trimmed to include only ray intercepts that travel to the solar cell surface. The solar cell is located off-focus so that rays from the reflector intercept the cell surface according to a predetermined mapping.

Abstract:

A bookbinding system and method of binding books including a cover/spine assembly having a relatively rigid cover section with a length and width at least as great as that of the stack of sheets to be bound and a spine section having a width greater than the height of the stack. The cover/spine assembly and the spine section are secured together along the length of the cover section so that the spine section can be folded along a first edge with respect to the cover/spine assembly. A heat activated matrix is disposed on the spine section including a central adhesive band and an outer band disposed between the central adhesive band and a second edge of the spine section. Binding is carried out by placing the stack over the cover section and folding the spine section over the edge of the stack. Preferably a second relatively rigid cover section is placed on top of the stack so that the outer adhesive band on the spine section will extend over second cover section. The central adhesive band is a low viscosity adhesive which, when activated, bonds the sheets of the stack to the spine section to form the spine of the bound book.
