    • An operable ramp is moveable between a raised position, in which the ramp forms a pair of steps, and a lowered position, in which the operable ramp provides an inclined surface. The operable ramp includes a first panel rotatably coupled about a first axis that moves back and forth when the operable ramp moves between the lowered position and the raised position. A link is rotatably coupled to the first panel about a second axis and is itself rotatable about a fixed third axis. A second panel is rotatably coupled to the link between the second axis and the third axis, and a third panel is rotatably coupled to the second panel about a fourth axis. When the ramp moves between the raised and lowered positions, the fourth axis rotates about a fixed fifth axis. A linkage selectively rotates the first panel about the first axis.

    • A truss rod adjustment device includes a truss rod gear assembly, an adjustment gear assembly and a base. The truss rod gear assembly includes an end shaped to fit in and engage a truss rod wrench socket attached to a neck of a guitar. The adjustment gear assembly includes an adjustment socket shaped to receive and engage a wrench. The base attaches to the neck of the guitar and holds the truss rod gear assembly in position to engage the truss rod wrench socket. The base also holds the adjustment gear assembly in position both to engage the truss rod assembly gear assembly and to position the adjustment socket to be accessible through a hole in a back of the guitar.

    • A ramp assembly for providing a transition surface between a vehicle floor and an alighting surface is disclosed. The ramp assembly includes a ramp portion that is rotatable between a stowed position and a deployed position. A sensor senses an angle of the ramp portion relative to a horizontal plane and provides a sensor output that corresponds to the angle of the ramp portion relative to the horizontal plane. The ramp assembly further includes a controller that receives the sensor output and an alert device. The controller controls the alert device to provide an alert when the angle of the ramp portion relative to the horizontal plane reaches a predetermined value.
    • 公开了一种用于在车辆地板和下落表面之间提供过渡表面的斜坡组件。 斜坡组件包括可在收起位置和展开位置之间旋转的斜坡部分。 传感器感测斜面部分相对于水平面的角度,并且提供对应于斜面部分相对于水平面的角度的传感器输出。 斜坡组件还包括接收传感器输出的控制器和警报装置。 当斜坡部分相对于水平面的角度达到预定值时,控制器控制警报装置提供警报。

    • A catheter shaft includes an inner layer of a first polymeric material, an intermediate layer of a second polymeric material, an outer layer of a third polymeric material, a first wire reinforcing layer encapsulated between the inner and intermediate layers, and a second wire reinforcing layer encapsulated between the outer and intermediate layers. Typically, the first wire reinforcing layer includes one or more metallic wires helically wound in one direction and the second wire reinforcing layer includes one or more metallic wires helically wound in the opposite direction. The intermediate layer is bonded to the inner and outer layers, as by extruding layers over one another or by thermal lamination or reflow bonding. Typically, the intermediate layer has a larger yield strain and/or a lower flexural modulus and/or a lower durometer than at least one of the inner layer and the outer layer.
    • 导管轴包括第一聚合物材料的内层,第二聚合物材料的中间层,第三聚合物材料的外层,密封在内层和中间层之间的第一丝线增强层,以及第二丝线增强层 封装在外层和中层之间。 通常,第一线加强层包括沿一个方向螺旋缠绕的一个或多个金属线,第二线加强层包括沿相反方向螺旋缠绕的一根或多根金属线。 中间层通过彼此挤压层或通过热层压或回流焊接而结合到内层和外层。 通常,中间层具有比内层和外层中的至少一个更大的屈服应变和/或较低的弯曲模量和/或较低的硬度。

    • A system and method for determining the genetic data for one or a small set of cells, or from fragmentary DNA, where a limited quantity of genetic data is available, are disclosed. Genetic data for the target individual is acquired and amplified using known methods, and poorly measured base pairs, missing alleles and missing regions are reconstructed using expected similarities between the target genome and the genome of genetically related subjects. In accordance with one embodiment of the invention, incomplete genetic data is acquired from embryonic cells, fetal cells, or cell-free fetal DNA isolated from the mother's blood, and the incomplete genetic data is reconstructed using the more complete genetic data from a larger sample diploid cells from one or both parents, with or without genetic data from haploid cells from one or both parents, and/or genetic data taken from other related individuals.
