  • Publication number: 20260143100
    Abstract: A system and method for wildfire detection, monitoring, and consequence modeling integrate digital cameras with artificial intelligence to identify, track, and predict fire behavior. The system processes camera imagery, satellite data, environmental inputs, aircraft telemetry, and contextual information to detect ignition points, triangulate fire locations, and model projected fire spread. A fire propagation engine generates maps, graphs, and consequence estimates, including burned area, affected infrastructure, population exposure, and financial loss. Alerts are triggered based on detection and modeled impact, with filters to suppress false positives, merge repeated detections, and escalate based on user-defined risk thresholds. The system includes tools for managing prescribed fires, tracking smoke-only detections, and customizing alert logic by geography, asset proximity, or scenario. External datasets may be ingested via API or file upload to support consequence scoring and operational prioritization.

  • Publication number: 20250305656
    Abstract: A wall wash lighting fixture includes an input end at which light enters the fixture and an output end at which light exits the fixture. A longitudinal axis of the fixture extends longitudinally from the input end to the output end. The fixture includes a light source for emitting light into an interior of the fixture at the input end of the fixture. The fixture includes an optical element for receiving the light from the input end of the fixture. The optical element has a plurality of extraction elements for altering a path of the light passing through the fixture, such that light exiting the fixture at the output end of the fixture is directed laterally with respect to the longitudinal axis.

  • Patent number: 12342671
    Abstract: Aspects of the present disclosure include a light emitting diode (LED) module including a plurality of LEDs, each of the plurality of LEDs being spaced apart from one or more neighboring LEDs by a spacing, a plurality of optics each disposed over a corresponding LED of the plurality of LEDs, each of the plurality of optics having a radius, and a plurality of LED chips disposed within the plurality of LEDs and each having a LED light emitting surface having one or more sides with a length, wherein a ratio of the spacing, the radius, and the length is configured to cause a light emitted from the LED engine to be narrower than 14 degrees and with a relative Cd/lm greater than 10 and with a measured application color uniformity of less than 0.005 Du1v1.

  • Publication number: 20250075879
    Abstract: An optical element for a light fixture is adapted to receive light from a light source and to direct the light toward a light-emitting surface along an axis of the optical element. The optical element includes an inner surface disposed axially around and at least partially enclosing the axis of the optical element, the inner surface at least partially containing the light within the optical element by internal reflection of the light, the inner surface being defined by at least two geometric shapes coaxially disposed with respect to the axis of the optical element.

  • Patent number: 5012753
    Abstract: A light weight and collapsible platform and platform support structure usable as the deck and central structure of a folding boat and of a levelable, raised platform tent camper. This collapsible platform support structure is a unique arrangmeent of compression carrying arms radiating out from a central hub and jacking device, with an arrangement of tension carrying cables linking and supporting the radial arms into a rigid geometry. By concept and design the structure maximizes horizontal platform area for a minimum of weight and structure. Light weight allows transportability and collaspsibility allows stowability. The structure is opened from a collapsed state to a rigid erected state by operation of the jack, which moves the cable hub away from the arm hub. This action rotates the arms downward, loading the arms in compression and the cables and platform in tension, eventually locking the the structure into it's rigid erected geometry.

  • Patent number: 4920909
    Abstract: A rotatable wheel is mounted under a sailboat or other boat and shaped in a manner such that it will be efficient in developing a hydrodynamic lifting force to function as the boat's primary keel to resist leeway and provide directional stability. The wheel or wheels can also be used to ramp launch or haul the boat and to roll the boat about on land. In order to reduce hydrodynamic drag, a tire fitted onto the wheel forms a continuous and fair surface with the wheel wall.
