Sequential and coordinated flashing of electronic roadside flares with active energy conservation
First Claim
1. An electronic light emitting flare comprising:
- a housing comprising a top wall, bottom wall and at least one side wall, wherein at least a portion of the side wall is translucent and at least a portion of the top wall is translucent;
a plurality of light emitters positioned within the housing;
a power source; and
electronic circuitry connected to the power source and light emitters to drive at least some of the light emitters to emit flashes of light directed through said at least one translucent portion of the housing side wall; and
switching circuitry to switch back and forth between a) a side emitting mode wherein light emitters emit flashes of light directed through said at least one translucent portion of the side wall and b) a top emitting mode wherein light emitters emit flashes of light directed through said at least one translucent portion of the top wall.

Abstract
Electronic light emitting flares and related methods. Flares of the present invention include various features such as self-synchronization, remote control, motion-actuated or percussion-actuated features, dynamic shifting between side-emitting and top-emitting light emitters in response to changes in positional orientation (e.g., vertical vs. horizontal) of the flare; overrides to cause continued emission from side-emitting or top-emitting light emitters irrespective of changes in the flare'"'"'s positional orientation; use of the flare(s) for illumination of traffic cones and other hazard marking or traffic safety objects or devices, group on/off features, frequency specificity to facilitate use of separate groups of flares in proximity to one another, selection and changing of flashing patterns and others.
