    摘要： A method for increasing stiffness of bearing strata formed of soil, rock or other geomaterial includes the steps of injecting non-hardening pre-compression fluids, in the form of viscous non-hardening slurries that are pressurized beneath a foundation tip for extended periods of time, into the bearing strata to cause pre-compression of the bearing strata. This enhances end bearing capacity in poorly draining soils by providing more time to squeeze water from voids in the poorly draining soils. The bearing strata may also be mechanically pre-compressed. The non-hardening pre-compression fluids may be exchanged with grout to fill a void formed by cavity expansion and previously occupied by the non-hardening, pre-compression fluid. This grout is cured without external additional pressure. Grout may be used in lieu of non hardening pre-compression fluids to affect end bearing enhancement provided that external additional pressure is not applied to the grout while it cures.

    摘要翻译： 用于增加由土，岩石或其它地质材料形成的承载层的刚度的方法包括以粘性非硬化浆料的形式注入非硬化的预压缩流体的步骤，所述非硬化预压缩流体在基础尖端下长时间加压 ，进入轴承层以引起承载层的预压缩。 这通过提供更多的时间从排水不良的土壤中的空隙中挤出水来增强排水不良的终端承载能力。 轴承层也可以机械预压缩。 非硬化预压流体可以与浆料交换以填充由空腔膨胀形成的空隙，并且预先被非硬化的预压缩流体占据。 这种灌浆在没有外部附加压力的情况下固化。 可以使用灌浆来代替非硬化的预压缩流体，以影响端部轴承的增强，只要在固化时外部额外的压力不施加到灌浆。

    摘要： A system and method for estimating a location of an object or vehicle is provided. Images of a region encompassing the object are obtained, providing a three dimensional (3-D) view frame of the region. 3-D view frames are collected along a direction of travel of the object. A 3-D map is generated along the direction of travel of the object, the map based on the 3-D view frames and further based on an estimate of motion of the object at times associated with the 3-D view frames. A first set of features is extracted from the 3-D map. A geo-referenced feature database is searched for a second set of features that match the first set of features. A geo-location associated with the second set of features is retrieved from the feature database. The location of the object is estimated based on the retrieved geo-location.

    摘要： A fluid pulse damper having increased dynamic range and sensitivity, being especially useful in suppressing pulsations in the fuel supply rail of an internal combustion engine. The damper is a longitudinal gas-filled plastic pillow having walls formed by opposed flexible short sides and opposed flexible long sides, and includes at least one internal self-contact element, and preferably a plurality of such elements. As the short sides flex, the elements make contact internally, shifting the damper into a different compression regime and extending the pressure/response over an increased range of pressures. A feature of some embodiments is that the inner surface within the contact elements is shifted into tension after the elements make contact, thereby stiffening the damper and increasing the damper's resistance to further deformation. The damper is formed of a plastic such as ultra-high molecular weight polyethylenes, high flow polyetherimides, or tubing grade polyphthalamides.
