6542302, Apr 1, 2003

Filed:

Sep 24, 2001

Appl. No.:

09/961750

Inventors:

John W. Cross - Overland Park KS

Assignee:

Bushnell Corporation - Overland Park KS

International Classification:

G02B 110

US Classification:

359581, 359582, 359507

Abstract:

A coated lens for use in a riflescope, telescope, spotting scope, binoculars, or the like is provided. The coating on the lens comprises two layers, an anti-reflective layer adjacent the lens and a hydrophobic layer disposed on the anti-reflective layer. The hydrophobic layer preferably includes an organosilane compound. Advantageously, the coating does not significantly reduce light transmission through the lens.

Appl. No.:

11/079035

Inventors:

John Cross - Overland Park KS, US
Christopher Lalik - Overland Park KS, US
John DeCastro - Lenexa KS, US
Richard Ball - Overland Park KS, US

Assignee:

Bushnell Performance Optics - Overland Park KS

International Classification:

G01C 21/00

US Classification:

701213, 701211, 701207, 701200, 345156

Abstract:

A GPS device and method for converting display information between a first display mode and a second display mode by negativizing pixels or other image elements, wherein negativizing entails converting relatively larger areas of lighter image elements to darker image elements and converting relatively smaller areas of darker image elements to lighter image elements so as to result in reduced total emission of light.

Appl. No.:

11/314593

Inventors:

John Cross - Overland Park KS, US
Jordan Vermillion - Overland Park KS, US

Assignee:

Bushnell, Inc. - Overland Park KS

International Classification:

F41G 3/06
G01C 3/04

US Classification:

42142, 356 401

Abstract:

A handheld rangefinder device operable to determine ballistic hold over information is disclosed. The rangefinder device generally includes a range sensor operable to determine a first range to a target, a tilt sensor operable to determine an angle to the target relative to the device, and a computing element, coupled with the range sensor and the tilt sensor, operable to determine a hold over value based on the first range and the determined angle. Such a configuration facilitates accurate firearm and bow use by providing ranges and hold over values without requiring time-consuming and manual user calculations.

John W. Cross - Overland Park KS, US

Assignee:

Bushnell, Inc. - Overland Park KS

International Classification:

G01C 3/08

US Classification:

356 401, 356 301, 356 501, 356 51

Abstract:

A handheld rangefinder device operable to determine ballistic hold-over information is disclosed. The rangefinder device generally includes a range sensor operable to determine a range to a target, a memory storing a database of ranges and corresponding hold-over values for a default sight-in distance, and a computing element, coupled with the range sensor and the memory. The computing element may calculate an adjusted hold-over value based on the range and an actual sight-in distance. Additionally, a tilt sensor may be included to provide information for calculating an angle-adjusted hold-over value. Such a configuration facilitates accurate firearm use by providing ranges and hold-over values without requiring time-consuming and manual user calculations.

Filed:

Nov 5, 2001

Appl. No.:

10/011629

Inventors:

John Cross - Overland Park KS, US
Christopher Lalik - Overland Park KS, US

International Classification:

G02B023/00

US Classification:

359/424000, 359/399000, 359/428000

Abstract:

Reticles and scopes using reticles are provided with increased visibility in low-light conditions by illuminating the reticle using the light emitted by a quantity of photoluminescent material. The photoluminescent material may be placed on the reticle itself or emit light which is cast onto the reticle. In some forms, the reticle is entirely coated with the photoluminescent material and in other forms, the photoluminescent material is selectively deposited on a portion of the reticle or an area adjacent the reticle. In other forms, the photoluminescent material is located remote from the reticle and the light emitted from the reticle is transmitted to the reticle. Alternatively, the light may be transmitted directly into a disc of optical material which has an area etched into a reticle pattern whereby the transmitted light escapes from the disc through the etched out portion and provides an illuminated reticle pattern which is visible in low light conditions.

Abstract:

A telescopic sight () for automatically compensating for bullet trajectory deviations is disclosed. The sight () includes a user input () and an electronic port () for communicating ballistic, calibration and user preference information to the sight (). The sight () further includes a ranger finder () and an array of ambient condition sensors () for automatically generating target distance information and ambient condition information. A processor () uses the ballistic, calibration, user preference, distance and ambient condition information to calculate bullet trajectory deviation compensation information. The processor () presents the compensation to the user in the form of a compensation reticle () or a compensation value ().
