Abstract: A bandsaw makes simultaneous, spaced-apart cuts in hard or soft materials with a single bandsaw blade. The invention is ideally suited to cutting spaced-apart parallel surfaces to form support blocks, however, different embodiment may be controlled or programmed to make parallel or non-parallel cuts at varying angles. The single bandsaw blade rides on circular wheels on both sides of a gap or passageway, such that a first portion of the blade crosses the passage along a first, upper path, and a second portion of the bandsaw blade crosses the passage along a second, lower path. A table moves the material through the passage, whereupon the material is simultaneously cut along two planes corresponding to the upper and lower paths of the bandsaw blade. A preferred embodiment includes a first set of upper and lower wheels on one side of the passage, and a second set of upper and lower wheels on an opposing side of the passage.

Abstract: Antennas using nonwoven geotextiles with embedded metallic or other wave carrying fibers are described herein. The geotextiles antennas are designed to be an internal, integral part of the nation's infrastructure. Geotextile antennas are flexible and easily conform to natural and manmade surfaces such as exterior building surfaces, for example, roads, roofs and bridges. Geotextile antennas are considerably less vulnerable to damage and probably much less expensive than the current, highly vulnerable and costly cell towers. In particular, geotextiles used in roads are especially well protected by the asphalt pavement above. The fabric-based conformal antenna enhances the usefulness and reliability of the communication infrastructure which is exceedingly vulnerable to vandalism, terrorism and natural disasters.
