Filed:

Jun 27, 2002

Appl. No.:

10/184847

Inventors:

George R. Hull - Portland OR
Robert M. OLoughlin - Portland OR
Terry P. OLoughlin - Portland OR

Assignee:

Lightshot Systems, Inc. - Portland OR

International Classification:

F41G 326

US Classification:

434 22, 434 21, 273365, 273371, 463 51, 463 52, 463 53

Abstract:

A pattern testing board is able to detect an emission beam such as a laser or light beam from a shooting system. A pattern testing board includes a plurality of paired emission beam sensors and hit indicators. Each emission beam sensor is responsive to a detected emission beam and each hit indicator signals the sensing of the emission beam by the associated emission beam sensor. Multiple pattern testing boards may be mounted together to provide a larger pattern testing system array. Further, an overlay with a representation thereon, a moving image display system, or a reflective moving image display system may be positioned in front of one or more pattern testing boards. Still further, the pattern testing board may be incorporated in a unique target system that includes the pattern testing board for determining the beam pattern emitted by the beam emitter, a level selection board for selecting a level of play; and a targeting game board having a plurality of targets.

International Classification:

F41G003/26

US Classification:

434/022000

Abstract:

A pattern testing system is able to detect an emission beam such as a laser or light beam from a shooting system. A single pattern testing board includes a plurality of paired emission beam sensors and hit indicators. Each emission beam sensor is responsive to a detected emission beam and each hit indicator signals the sensing of the emission beam by the associated emission beam sensor. Multiple pattern testing boards may be mounted together to provide a larger pattern testing system array. Further, an overlay with a representation thereon, a moving image display system, or a reflective moving image display system may be positioned in front of one or more pattern testing boards.

Assignee:

LightShot Systems, Inc. - Portland OR

International Classification:

F41G 326

US Classification:

434 22

Abstract:

A system for simulating shooting sports includes a non-projectile ammunition transmitter system that is retrofittable to any standard firearm having an ammunition chamber, a barrel, and a firing pin and a self-contained receiver system. The transmitter system includes an actuating beam cartridge and an adjustable beam choke. The beam cartridge includes a first actuating beam emitter responsive to the firing pin. The beam choke includes a second emission beam emitter responsive to the first actuating beam. The receiver system is a self-contained reusable target having beam sensors and hit indicators. The beam sensors are "triggered" when the emission beam "hits" or is "sensed by" the beam sensors. When the beam sensors sense the emission beam, they cause the hit indicators to indicate that the target has been "hit" by the emission beam. The target may also include at least one triggering motion detector that detects a triggering motion that is associated with the target being launched into the air.

Appl. No.:

5/561740

Inventors:

George Robert Hull - Beaverton OR

Assignee:

Tektronix, Inc. - Beaverton OR

International Classification:

H02M 748

US Classification:

321 2

Abstract:

A high efficiency switching drive for a resonate power transformer having the ability to maintain a constant output voltage over a wide range of source voltage variation while maintaining good power conversion efficiency is provided. A transistorized class-C oscillator has means to saturate the transistors during conduction time to allow the transistor voltage to remain small as opposed to a current source as in the conventional class-C oscillator.
