Abstract: A computer program product and method for locating edgeless areas within digital images, by locating a pixel with a luminance value that does not vary from its major neighbors by more than a fixed tolerance, and seeking to expand an edgeless area about such pixel by examining the variance in luminance of pixels about the selected pixel and if within a preset tolerance, including such neighbors within an edgeless area, and optionally further including pixels otherwise not includable within the edgeless area if local variations in luminance suggest a noisy background for which the tolerance may be increased.
Abstract: A system and method for internally supporting a flexible envelope such as an airship is described, comprising a truss structure and supporting struts attached to a central support member. The internal structure may be foldable so as to allow the envelope to be collapsed when not in use.
Abstract: A system and method for equalizing internal and external pressure on an enclosed vessel moving through a gas or fluid is described, thereby reducing hoop stresses imposed on the vessel by pressure differentials. The vessel is divided into multiple chambers, and the internal pressure of a chamber may be equalized with an external pressure proximate the chamber through the use of a valve or controllable vent.
Abstract: An electrical contact modifier is configured to allow the use of a “single-element” medium base light bulb in a three-way lamp holder/switch. The device allows the three-way switch to replicate the “OFF-ON” functionality of a standard one-way light switch.
Abstract: The invention comprises a distributed direct retinal display projection system that can be fabricated as an embedded, integral part of an eyeglasses frame and can be configured to address a wide range of commercial, consumer and military applications. A system is described comprising a video processing module that may worn on a belt or carried in a pocket, which transmits an image through a multi-waveform optical cable that is configured with a wave guide per pixel.
Abstract: A system and method for constructing an airship hull is described, comprising a plurality of flexible members disposed lengthwise about the perimeter of the airship skin. The flexible members can be held in place in sleeves on the skin of the airship. The ends of the flexible members are drawn toward one another by tensioning means, causing the members to bow outwardly from a central axis and providing a rigid structure for the skin.
