摘要： A railroad collision avoidance system and method are disclosed that utilize impulse radio technology to effectively warn a person when there is a locomotive in their vicinity. In one embodiment, the railroad collision avoidance system includes a transmitting impulse radio unit coupled to a locomotive and a receiving impulse radio unit coupled to a vehicle. The transmitting impulse radio unit operates to transmit an impulse radio signal towards the vehicle when the locomotive is a predetermined distance from a railroad crossing. Upon receiving the impulse radio signal, the receiving impulse radio unit makes sure the person operating the vehicle is informed about the potentially dangerous situation. Several embodiments of the railroad collision avoidance system and method are disclosed all of which operate to warn a person when there is a locomotive in their vicinity.

摘要： A danger proximity warning system and method are disclosed that utilize ultra wideband (UWB) technology to effectively warn a person when there is a potentially dangerous situation in their vicinity. In one embodiment, the danger proximity warning system includes a transmitting UWB radio coupled to a first object and a receiving impulse radio unit coupled to a second object. The transmitting impulse radio unit operates to transmit an UWB signal towards the second object when the first object is a predetermined distance away. Upon receiving the UWB signal, the receiving UWB radio makes sure a person associated with the second object is informed about the potentially dangerous situation. Several embodiments of the danger proximity warning system and method are disclosed all of which operate to warn a person when there is a potentially dangerous situation in their vicinity.

摘要： A washing machine drain hose connector for coupling the discharge hose pipe to a sewer drain pipe is made of pliable, elastomeric material. The connector shape is a staggered, coaxial series of cylindrical sleeve sections connected end to end by integrally molded annular shoulders. The cylindrical sleeve radii increase progressively along the sequence of joined sleeve section. A largest sleeve section is folded back over the next-to-largest sleeve section to frictionally grip the drain pipe on both its inside and outside surfaces. The smaller sleeve sections grip various standard sizes of washing machine discharge hose pipes inserted into the drain pipe. All sleeve sections are sized to interfere, so that they are stretched around the pipes and exert friction forces to hold the pipes in coupled relation. To increase the frictional holding force, the sleeve sections (except the largest) are all at least as long as the sleeve radius, the sleeve walls are smooth (i.e., without ribs or other protrusions), and the sleeve walls are thin enough that they can roll over and become wedged in the space between the pipes when water back pressure tends to blow the hose pipe out of the drain pipe.
摘要翻译： 用于将排放软管管连接到下水道排水管的洗衣机排水软管接头由柔韧的弹性体材料制成。 连接器形状是一个交错的同轴系列的圆柱形套筒部分，通过整体模制的环形肩部端对端连接。 圆柱形套筒半径沿连接的套筒部分的顺序逐渐增加。 最大的套筒部分被折叠在下一个最大的套筒部分上以在其内表面和外表面上摩擦地夹紧排水管。 较小的套管部分抓住插入排水管的各种标准尺寸的洗衣机排放软管。 所有套筒部分的尺寸都可以干涉，以便它们在管道周围拉伸并施加摩擦力以将管道保持在耦合关系。 为了增加摩擦保持力，套筒部分（除了最大的）至少与套管半径一样长，套筒壁是光滑的（即没有肋或其它突起），并且套管壁足够薄，使得它们 当回水压力倾向于将软管从吹管排出时，可以在管道之间的空间中滚动并变形成楔形。
