20040263622, Dec 30, 2004

Filed:

Jul 31, 2003

Appl. No.:

10/633050

Inventors:

Michael Dennis - Scappose OR, US
David Dennis - Scappoose OR, US

International Classification:

H04N007/18

US Classification:

348/143000

Abstract:

An multi-information-character imaging surveillance system and methodology which employs an optical, daytime, color video imager, an optical, nighttime, light-intensified, black-and-white video imager, a thermal imager, and housing structure closely containing each of said imagers as an assembly in respective, cooperative, relative positions and conditions wherein they share a substantially common point of view. Each of the three imagers has an imaging axis, and the three imaging axes are oriented whereby they are substantially bore-sight aligned at infinity. Further included and employed is computer-controllable, motor-actuatable drive structure which is operatively and drivingly connected to the housing structure, and thus to the contained imager assembly, for producing unitized, selective and controlled surveillance-motion tracking via generally horizontal panning and general vertical tilting motions.

International Classification:

H04N007/18

US Classification:

348143000

Abstract:

A plural-mode, plural-receptor surveillance imaging system and methodology which offer very simple, versatile one-handed control over the operations and viewing orientations of three different surveillance imagers, thus to minimize the tasks involved in controlling the specific surveillance views which are established and presented by these imagers. Provided for allowing such control are a one-hand-operable, intuitive touch-screen and joystick controller structure, and a appropriate computer for translating user control actions accurately into changes in system behavior. This one-handedness characteristic promotes an operational environment in which the larger share of a user/operator's attention can successfully be focused on the received surveillance imagery, per se, rather than upon details of operating a control.

International Classification:

H04N005/225

US Classification:

348217100

Abstract:

An imaging surveillance system and methodology which employs a nighttime, intensified-light, black-and-white imager. This imager includes a light intensifier which, from a methodologic point of view, and through an appropriate input lens structure, directly gathers available nighttime scene light, and feeds substantially all of this light, after intensification takes place, to a single-CCD-device, black-and-white camera which, in a non-beam-splitting manner converts this received light to a black-and-white video image output data stream. Another way of expressing and visualizing the methodology implemented by the present invention is to think of it, in the context of utilizing a properly deployed light intensifier, as including the steps of (a) creating a light-intensified image which is derived from a non-light-intensified nighttime field of view, and (b) processing that intensified image with an optical-to-electronic imaging instrumentality so as to produce an electronic-data output stream which contains solely achromatic optical image information.

Appl. No.:

Inventors:

Michael Dennis - Scappoose OR, US
David Dennis - Scappoose OR, US

International Classification:

H04N007/18

US Classification:

348143000

Abstract:

A multi-information-character, surveillance imaging system and method employing a plural-imager, assembly of surveillance imagers including (a) an optical, daytime, color imager, (b) an optical, nighttime, light-intensified, black-and-white imager, and (c) a thermal imager, and featuring a pair of side-by side adjacent, readily co-viewable, video image display structures. One of these display structures is dedicated to the presentation of thermal imagery, and other is selectively and changeably dedicatable, at any time, to any one alone of the three system imagers. Interconnect structure, including a user-operable controller, operatively and communicatively interconnects the imagers and the display structures in a manner permitting selective user switching of communication between the “other” display structure and one or another of the daytime, nighttime and thermal imagers.

Appl. No.:

Inventors:

David Dennis - St. Helens OR, US

Assignee:

Guardian Protective Technologies Inc. - Walnut Creek CA

International Classification:

F41H 1/02
A44B 11/25

US Classification:

2 25, 2457311

Abstract:

Bulletproof vests, body armor, and other tactical vests with quick release buckle mechanisms are described along with methods of their use. The multi-point buckle mechanisms release upon rotating a shaft, allowing the vest panels and straps to fall cleanly to the ground without knocking the wearer off balance. Waist belt clips allow a wearer to put the vest on over his or her head without engaging the emergency release, or the multi-point buckle mechanism can release only the waist straps upon rotating the shaft in the opposite direction. A flap protects the rotatable quick release mechanism from inadvertent activation.
