    • A modular lightweight bridge comprises a pair of tubular truss formed spans, each of which include a plurality of modules hinged to one another at locations on the bottom of the bridge for folding the bridge for transport prior to deployment of the bridge. Each span has a unique high strength fabric deck or roadway surface tensioned across the upper side of the truss chord members. The bridge is uniquely captively mounted on a trailer by rollers for transporting the bridge when it is in its folded mode. When the bridge is to be deployed, each span is unfolded by pivoting the modules with respect to one another about vertical axes so that the spans expand longitudinally with respect to the trailer. The spans are then pivoted 90.degree. downwardly about longitudinally extending horizontal axes and the bridge rolled rearwardly from the trailer over the gap to be spanned. Due to the unique captive roller interconnection between the bridge assembly and its transport-deployment trailer, the trailer can thereafter be stored beneath the deployed bridge hanging down into the gully or gap. When a decision is made to remove the bridge, the trailer can be towed from either side back over the bank of the gap and the bridge refolded for mounting on and transport by the trailer.
    • 模块化轻型桥梁包括一对管状桁架跨距,其中每一个包括多个模块,所述多个模块在桥的底部处的位置处彼此铰接,用于在桥梁展开之前折叠桥架用于运输。 每个跨度都具有独特的高强度织物甲板或桁架弦杆构件的上侧张紧的道路表面。 桥梁独特地通过滚轮独立地安装在拖车上,用于在桥梁处于折叠模式时运输桥梁。 当要部署桥梁时,通过围绕垂直轴线相对于彼此枢转模块来展开每个跨距,使得跨度相对于拖车纵向地扩展。 然后,跨越纵向延伸的水平轴线向下枢转90°,并且桥从拖车向后滚过间隙以跨越。 由于桥接组件与其运输部署拖车之间的独特的互锁辊互连,此后可将拖车储存在部署的桥下,垂直向下延伸到沟槽或间隙中。 当决定拆卸桥梁时,拖车可以从任何一侧拖到间隙的堤岸上,并且桥梁被重新折叠以安装在拖车上并由拖车运输。

    • A routing process for automatic computer aided routing of customizing conductors in a universal array which has a single customizing conductive layer is improved by executing a pathfinding routing process for conductors which connect pins on the same row before routing other conductor types. Routing of conductors which connect a pin on the side surface to a pin in the basic unit row region is improved by initially restricting permissible routes to be within a set of three contiguous rectangles. Routing opportunities for potentially failed conductors are increased by allowing customizing conductors to extend parallel to the length of the basic unit rows in the region between adjacent tunnel ranks in the final routing step. An improved custom IC results.The conductor number of the shortest and the longest conductor in each class is stored separately from the routing grid matrix so that these numbers can be directly retrieved as needed.Since the conductors are arranged in class and length order in the wiring matrix, the routing process in going through any class of conductors in an attempt to route them retrieves them in a length order (long-to-short or short-to-long).
    • 在具有单个定制导电层的通用阵列中定制导体的自动计算机辅助布线的布线过程通过对在布置其它导体类型之前连接同一行上的引脚的导体执行寻路布线处理而得到改进。 通过初始限制在三个连续矩形的集合内的可允许路线,改进了将侧表面上的销连接到基本单位行区域中的销的导线的布线。 通过允许定制导体平行于最终路由步骤中相邻隧道队列之间的区域中的基本单位行的长度来扩展潜在故障导体的路由机会。 改进的定制IC结果。 每个类中最短和最长导体的导体数与路由网格矩阵分开存储,以便可以根据需要直接检索这些数字。 由于导体按照布线矩阵中的等级和长度顺序布置,所以通过任何类别的导体尝试路由它们的布线过程以长度顺序(长到短或短到长)取回, 。

    • A compact attic mounted solar heating pack assembly includes an enclosed sheet metal plenum fixedly hung by straps from the attic rafters at the apex of north and south facing roofing sections. An electric powered blower fixed to the plenum has an air inlet open to the attic interior below the south facing roof section. An air outlet of the blower opens directly to the plenum interior. A plurality of flexible ducts are coupled to respective air outlets within the plenum at one end with their opposite ends terminating in diffusers mountable within holes formed within the underlying ceiling for delivering air from the plenum chamber directly to the building interior below the attic floor. A first normally open cooling thermostat is mounted within the attic at the apex, beneath the south facing roof section. A plastic heat barrier is hung from the ridge pole and extends well below the plenum chamber to trap heated air within the section of the attic beneath the south facing wall. A second heating thermostat is mounted within the building interior below the ceiling and preferably on an interior partition wall and is series connected with the blower motor and the first attic mounted thermostat and connectable to a source of electrical current. The normally open thermostat closes when room heat is needed and the temperature in the attic is above 70 degrees to provide an effective independent supplementary heating unit for the building.

    • Apparatus and method for measuring fluid velocity in a conduit or in open space comprises providing a laser which sends a beam through the fluid, measuring how the beam deflects due to the effect of transverse-moving fluid on the beam, and calculating velocity based on the deflection. The laser beam is one which causes thermal blooming within the fluid and that causes the beam to deflect as a function of the velocity of the fluid. The beam deflection is directly or indirectly measured, for example by looking at the movement of a beam spot on a target, or by sensing the change in intensity of the beam at a target.

    • A device and method of geolocating a transmitter. First and second receivers, in motion, receive a signal from the transmitter. Digitizers in the receivers digitize the signal. Converters in the receivers for converting the digitized signals to complex-valued signals. Transmitters on the receivers transmit their digitized signals, locations, and velocities at the time the signal was received to a processor. A central processing unit on the processor determines a difference in radial velocities of the receivers relative to the transmitter. The difference in radial velocities and delay time between the signals received at the receivers are used to geolocate the transmitter.
