    • A kinetic therapeutic table 10 having a frame 12, a planar patient support 14 mounted to the frame 12 for rotation about an elongate axis substantially aligned therewith and adjustable vertically at its foot 20 and head 18 ends. Symmetrical laterl support packs 114 at opposite sides of the patient's torso have laterally offset mountings for adjusting of the width therebetween by reversing their locations. Outer lateral leg supports 110 are mounted to the frame 12 and have a track 184 at their top surface for slideable mounting of both knee restraints 182 and foot supports 202 at selected positions therealong. The patient support 14 comprises a planar frame with a plurality of panels 88 removably mounted thereto by means of pins 96 actuated by a lever arm 100. A patient support 14 drive motor 28 provides rotary drive to the patient support 14 through a worm gear 40 locked to a geat linkage, so that it may be stopped and held by the worm gear 40 in any angular position by switching power off to the motor 28. The worm gear 40 is manually disengageable from the remainder of the gear linakge to enable manual movement of the patient support 14 to a horizontal position. A locking pin 76 is automatically biased against a drive ring 22 and springs into a pin hole 78 therein when the horizontal position is reached. The patient support 14 is mounted at one end of its pivot axis to the frame 12 by a ball 19 and socket 21 connection. The other end is connected to the drive ring 22 which is rotatably mounted to the frame 12 by means of idler wheels 26 and is otherwise rotatably driven by the motor 28 through the gear linkage. A electronic control circuit controls application of power to the motor 28 for selectively adjsutable periodic movement of the patient support 14.
    • 具有框架12的动力治疗台10,安装到框架12上的平面患者支架14,用于围绕其基本上与之对准的细长轴线旋转并在其脚部20和头部18处垂直调节。 在患者躯体的相对侧的对称的后侧支撑包114具有横向偏移的安装件,用于通过颠倒其位置来调整其间的宽度。 外侧腿支撑件110安装到框架12上,并且在其顶表面上具有轨道184,用于可滑动地将两个膝部约束装置182和脚支撑件202安装在其所选择的位置。 患者支架14包括一个平面框架,多个面板88借助于由杠杆臂100驱动的销96可移除地安装在其上。患者支架14驱动马达28通过蜗轮40锁定来向患者支撑件14提供旋转驱动 通过将动力切断到马达28,蜗轮40能够被蜗轮40停止并保持在任何角度位置。蜗轮40可手动地脱离齿轮线圈的其余部分,从而能够手动移动 患者支撑件14到水平位置。 当达到水平位置时,锁定销76自动地偏压驱动环22并弹簧到其中的销孔78中。 患者支撑件14通过球19和插座21的连接被安装在其枢转轴线的一端到框架12。 另一端连接到驱动环22,该驱动环22通过惰轮26可旋转地安装到框架12上,并且由马达28通过齿轮联动装置另外旋转地驱动。 电子控制电路控制对电动机28的电力的施加,用于患者支撑件14的可选择性可调节的周期性运动。

    • The all-optical pulse generating and amplifying system utilizes a phosphor that is excited by input light of a first wavelength and, in response, emits light of a second wavelength. The light emitted by the phosphor illuminates a bistable element which, at a pre-fixed intensity of the phosphor-emitted light, switches from non-transmissive state to transmissive state, thereby allowing the exit of light (also of first wavelength) emitted by an output light source as light pulse output of the system. An inhibitory light that also passes through the bistable element during its transmissive state quenches the phosphor light emission and returns the bistable element to its non-transmissive state and re-starts the process toward the next transmissive state. By gating the intensity, via selected non-linearity of the bistable element, of the light output in proportion to the intensity of the input light, the system can also function as an amplifier.
