Appl. No.:

8/937640

Inventors:

Chungte W. Chen - Irvine CA

Assignee:

Raytheon Company - Lexington MA

International Classification:

G02B 518

US Classification:

359569

Abstract:

A kinoform optical element (KOE) has different surface relief heights in different zones of the kinoform surface, in order to optimize the first order diffraction efficiency in each zone. By increasing the first order diffraction efficiency, noise as well as ghost image problems may be reduced and contrast and resolution may be enhanced. In an exemplary embodiment, each zone, or even different areas of the same zone, has a non-constant step height that is preferably defined by a predetermined relationship between an optimal step height and an associated predominant angle of incidence associated with that particular zone or area. In the case of an optical system having a relatively large aperture and a relatively narrow field of view, each point of the KOE sees the entire image; the associated predominant angle of incidence at that point may be defined by a so-called "marginal" ray from the center of the entire image space (i. e. , on the optical axis and at the effective "middle" of the usable depth of field). In the case of an optical system having a relatively small aperture and a relatively wide field of view , each point of the KOE sees only a portion of the image; the associated predominant angle of incidence at that point may be defined by an exemplary ray from the portion of the image space that is visible from that point.

Inventors:

DAVID SEAN CAPPS - SAN DIEGO CA, US

International Classification:

G06Q 50/26
A62C 37/50
G06Q 10/06

Abstract:

A system and method for documenting, monitoring, testing, inspecting, maintaining, and using fire equipment located at facilities including people, organizations, and properties as a part of users, places, and tools. The system and method operate via at least one computer, network, and user interface wherein the organization of data about users, places, and tools allows a user to assess the state and changes in states of users, places, and tools from which to make decisions about maintaining and using fire equipment and take associated action to fight fires and handle other emergencies. The system and method may further use machine learning and the Internet of Things to obtain, assess, and deploy data and tools.

Appl. No.:

14/880209

Inventors:

David Sean Capps - San Diego CA, US

International Classification:

H04L 29/08
A62C 37/50
G06F 17/30

Abstract:

A system for documenting, monitoring, testing, inspecting and maintaining fire equipment located at the property of secondary customers. Secondary customers include people, organizations and properties. The system saves all information collected on a server computer accessible via a computer network. This information is reviewable and editable by primary customers. In a preferred embodiment the server computer is located in the cloud and the computer network is the Internet. In a preferred embodiment, primary customers include fire inspection/repair/monitoring companies and fire departments using mobile computer devices. In another preferred embodiment, the software application has a customer relationship management tool allowing fire equipment, people, properties and organizations to be easily associated with one another. In another preferred embodiment, each piece of fire equipment is geographically mapped to a specific location via GPS or other mapping reference. Additionally, all fire equipment associated with a specific property, building or floor has all relevant information digitally captured and recorded into the cloud database. In another preferred embodiment, a fire department accesses fire equipment information during an exercise or emergency to direct responders. In another preferred embodiment, secondary customers with authorized access receive data and information regarding the status of the fire safety equipment, and receive analysis and recommendations from the service entities. Primary customers receive data and information regarding the status of fire safety equipment from the cloud database, and transmit analysis, records and recommendations to the secondary customers.
