20110043126 | Stepped intensity electric road flare - A stepped intensity electric road flare having a housing supporting a circuit. The circuit comprises an led light source, a power controller and a power supply. The power controller energizes the led light source with the power supply such that the led light source emits a varying light having at least one perceived fixed intensity within a range of emitted intensities. The road flare of the present invention provides a perceived steady light having a perceived fixed intensity during a portion or time zone of its waveform thereby communicating its exact location. In addition because its intensity changes during other portions or time zones of its waveform it also demands attention. The present invention is therefore an attention getting safety device communicating its exact location. The present invention both alerts drivers to a hazard and guides them past the hazard. In addition the emitted light of the present invention is of a reddish color and concentrated by an optic into a powerful light beam. An incendiary road flare also emits a powerful light having a reddish color and, at portions of its burn cycle, perceived as a steady light. An incendiary road flare also varies its intensity during its burn cycle. Therefore the electric road flare of the present invention emits light having characteristics similar to the characteristics of the light emitted by an incendiary road flare. The present invention therefore both alerts and guides drivers with an effectiveness similar to that of the incendiary road flare. | 02-24-2011 |
20130141255 | Visual Aid For Landing Helicopters - A visual aid for landing helicopters includes a plurality of weighted bases and a plurality of lights designed such that they can identify a helicopter landing zone during nighttime or during the bright sunlight. The components of the visual aid are designed to provide rapid identification of the landing zone, whether the pilot of the helicopter is flying with his unaided eye or with typical night vision goggles. The weighted bases have a large surface area and are coated with a highly visible fluorescent paint. The lights are designed to emit light having wavelengths, intensities and beam patterns which will not overwhelm night vision goggles but which will be acceptably visible to pilots flying without night vision goggles. The lights and weighted bases are color-coded such that they identify both the perimeter of the landing zone and the wind direction within the landing zone. | 06-06-2013 |
20130141926 | AUXILIARY LIGHTING FOR A MILITARY VEHICLE - Auxiliary lighting is added to military vehicles in response to civilian national emergencies permitting the vehicles to function as emergency vehicles. The auxiliary lights are attached to the military vehicles by employing military standard optical devices such as reflectors already mounted on the vehicles. This method of attaching the auxiliary lights avoids unacceptable modification of the military vehicles and reduces the complexity and time required to install the auxiliary lights. The attachment method also facilitates removal of the auxiliary lighting. Therefore temporary auxiliary lighting can be added to and removed from the military vehicle with a minimal use of tools or time. The auxiliary lighting is positioned on the military vehicle such that the emitted light beams are directed as required for the function the light is expected to perform. The auxiliary lights can be floodlights, warning lights, clearance or marker lights. | 06-06-2013 |
20130279157 | Multi-Functional Illuminator - A multi-functional illuminator comprising a directional illuminator and a removably attachable optic. The directional illuminator is typified by a flashlight projecting light forward to illuminate an object in front of the flashlight. The present invention discloses an optic removably attached to the directional illuminator intersecting and redistributing the light emitted by the directional illuminator to provide illumination satisfactory for tasks not achievable with the directional light beam. The optic employs reflection, refracting and/or diffusing optics to efficiently redirect the light. The optic can be designed so that the redirected light is distributed throughout the hemisphere, concentrated about a plane perpendicular to the axis of the directed light beam or to effect any one of a plurality of possible illumination patterns. If the directional illuminator comprises a covert design minimizing its lateral visibility, the optic can change this characteristic making it highly laterally visible. | 10-24-2013 |
