    • A stowable seat assembly is provided for use with a vehicle having a floor and a recess formed therein. The assembly includes a seat and a pivot tube adapted to be secured to the vehicle floor, with the seat being operatively pivotal about the pivot tube between a first, collapsed position and a second, stowed position with the seat being at least partially stowed within the vehicle recess. The seat passes through a third, upright position intermediate the first and second positions as the seat is pivoted between the first and second positions. The assembly further includes a torsion rod mounted on the pivot tube and free to twist, with the torsion rod being operatively coupled to the seat during pivoting of the seat toward and away from the third, upright position. The torsion rod provides a first biasing torque for assisting pivotal movement of the seat from the stowed position toward the upright position and a second biasing torque for assisting pivotal movement of the seat from the collapsed position toward the upright position.
    • 提供一种可收起的座椅组件,用于与其中形成有地板和凹部的车辆一起使用。 该组件包括适于固定到车辆地板上的座椅和枢转管,座椅可操作地围绕枢转管枢转在第一收缩位置和第二收起位置之间,座椅至少部分地收纳在座椅内部 车辆凹陷。 当座椅在第一位置和第二位置之间枢转时,座椅经过位于第一和第二位置的第三直立位置。 组件还包括安装在枢转管上并自由扭转的扭力杆,扭力杆在座椅朝向和远离第三直立位置转动时可操作地联接到座椅。 扭力杆提供第一偏压力矩,用于帮助座椅从收起位置朝向直立位置的枢转运动,以及用于辅助座椅从折叠位置朝向直立位置的枢转运动的第二偏压力矩。

    • Improved photonic band-gap optical fibre. The present invention relates in particular to improved photonic band-gap optical fibres that can confine light to a core region of the fibre by the action of both a photonic band-gap cladding and an antiresonant core boundary, at the interface between the core and cladding. According to embodiments of the present invention, a fibre has a core, comprising an elongate region of relatively low refractive index, a photonic bandgap structure arranged to provide a photonic bandgap over a range of wavelengths of light including an operating wavelength of light, the structure, in a transverse cross section of the waveguide, surrounding the core and comprising elongate relatively low refractive index regions interspersed with elongate relatively high refractive index regions and a relatively high refractive index boundary at the interface between the core defect and the photonic bandgap structure, the boundary having a thickness around the core such that the boundary is substantially anti-resonant at the operating wavelength of the fibre. In preferred embodiments, the core boundary is a relatively constant thickness region of glass around a hollow core.
    • 改进的光子带隙光纤。 本发明特别涉及改进的光子带隙光纤,其可以通过光纤带隙包层和反谐振核心边界在芯和包层之间的界面处将光限制在光纤的核心区域 。 根据本发明的实施例,光纤具有芯,其包括相对低折射率的细长区域,光子带隙结构被布置成在包括光的工作波长的光的波长范围内提供光子带隙,该结构 在波导的横截面中,围绕芯并且包括细长的相对较低的折射率区域,其散布有细长的相对高的折射率区域和在芯部缺陷和光子带隙结构之间的界面处的相对高的折射率边界, 边界具有围绕芯的厚度,使得边界在纤维的工作波长处基本上反共振。 在优选实施例中,芯边界是围绕中空芯的玻璃相对恒定的厚度区域。
