    • A reticle of a projectile weapon aiming system such as a riflescope includes a primary aiming mark adapted to be sighted-in at a first selected range and further includes a plurality of secondary aiming marks spaced apart below the primary aiming mark. The secondary aiming marks are positioned to compensate for ballistic drop at preselected incremental ranges beyond the first selected range, for a selected group of ammunition having similar ballistic characteristics. Angles subtended by adjacent aiming marks of the reticle can be adjusted by changing the optical power of the riflescope, to thereby compensate for ballistic characteristics of different ammunition. In some embodiments, the reticle includes a set of windage aiming marks spaced apart along at least one secondary horizontal axis intersecting a selected one of the secondary aiming marks, to facilitate compensation for the effect of crosswinds on the trajectory of the projectile.
    • 射击武器瞄准系统如路镜的掩模版包括适于在第一选定范围内被瞄准的主瞄准标记,并且还包括在主瞄准标记下方间隔开的多个次瞄准标记。 第二瞄准标记被定位成补偿具有类似弹道特性的选定组的弹药的超出第一选定范围的预选增量范围的弹道降落。 可以通过改变步枪镜的光功率来调整由掩模版的相邻瞄准标记所对向的角度,从而补偿不同弹药的弹道特性。 在一些实施例中,掩模版包括沿着与所选择的第二瞄准标记相交的至少一个副水平轴线间隔开的一组风向瞄准标记,以便于补偿侧风对射弹轨迹的影响。

    • There is provided a head immobilizer of the type which can be attached to a rigid backboard support, with the head immobilizer including a base and a pair of laterally extending side support panels. Each of these side support panels further comprises an inner panel and an outer panel, with the inner panel being conformable appropriately to a shape necessary to snugly support a head to be immobilized. The inner panel also includes an opening which effectively divides a portion of that inner panel into a pair of spaced inner support members extending laterally from the base. The outer panel has inner and outer edges, and is hingedly attached adjacent its inner edge to the inner panel such that it is foldable relative the inner panel to provide a substantially rigid brace for securing the inner panel in a desired immobilizing position. The outer panel also includes a cutout portion for providing substantial access to the opening of the inner panel when the inner panel is braced in a desired immobilizing position. The outer panel can be secured in a bracing position relative the inner panel, and the outer panel includes an attachment panel hingedly attached adjacent its outer edge for securing the outer panel in bracing position adjacent the base.
    • 提供了可以附接到刚性背板支撑的类型的头部防盗器,头部防盗器包括底座和一对横向延伸的侧面支撑面板。 这些侧支撑板中的每一个进一步包括内板和外板,其中内板适于适合于紧密地支撑固定头的形状。 内部面板还包括有效地将该内部面板的一部分分成从基部横向延伸的一对间隔的内部支撑构件的开口。 外板具有内边缘和外边缘,并且在其内边缘处铰接地附接到内板,使得其相对于内板可折叠,以提供用于将内板固定在期望的固定位置的基本上刚性的支架。 外板还包括切口部分,当内板被支撑在期望的固定位置时,该切口部分用于提供对内板的开口的实质接近。 外板可以相对于内板固定在支撑位置,并且外板包括邻近其外边缘铰接地附接的附接面板,用于将外板固定在与基座相邻的支撑位置。

    • A restraint stretcher comprising an envelope for receiving a rigidifying backboard, and having transverse straps for encircling the body of a patient at specific areas, the straps being mounted for longitudinal movement to fit various sizes of patient. The transverse straps and their anchorage brackets are readily individually removable for cleaning or replacement. The anchorage points can be located on the upper side of the stretcher for immobilizing smaller patients, or on the underside for immobilizing larger or adult patients. The stretcher is padded for patient comfort and includes laterally or outwardly projecting handles for transportation of the stretcher. A harness is provided to constrain the patient against longitudinal movement.
    • 约束担架,其包括用于接收刚性化背板的外壳,并且具有用于在特定区域围绕患者身体的横向带,所述带被安装用于纵向移动以适合各种尺寸的患者。 横向带及其固定支架可轻易地单独拆卸,以进行清洁或更换。 锚固点可以位于担架的上侧,用于固定较小的患者,或在下侧固定较大或成年患者。 担架为了患者舒适而被填充,并且包括用于运送担架的侧向或向外突出的手柄。 提供束带以约束患者的纵向运动。
