    • A charge pump is provided. The charge pump may include an oscillator, a first switch, a second switch, a capacitor/switch network, an error amplifier, an adjustable resistance circuit, a first switch driver, and a second switch driver. In one embodiment, the first and second drivers each receive the oscillator voltage, and drive the first and second switches, respectively. Further, the adjustable resistance circuit is connected in series with the first and second switch circuits. The charge pump is arranged in a closed loop with the error amplifier driving the adjustable resistance circuit. The resistance of the adjustable resistance circuit is modulated to regulate the output voltage.

    • A braking actuator for an ergonomic support is connected thereto by a Bowden cable. The actuator has a housing with pin slots, friction surfaces and a mount for a disk axle. A disk has frictional surfaces, holes with pin load edges, a Bowden cable wire seat that holds the Bowden cable end and an axle that is supported by the mount in the housing. The friction surfaces of the disk and housing engage each other to brake the actuator and the ergonomic support. A lever having pins is disposed on the housing such that the pins extend through the pin slots to engage the holes in the disk. Turning the lever disengages the friction surfaces and rotates the disk, thereby moving the ergonomic support. Releasing the lever engages the frictional surfaces such that movement of the ergonomic support is braked at a selected position.
    • 用于人体工程学支撑件的制动致动器通过鲍登缆绳连接到其上。 致动器具有壳体,其具有销槽,摩擦表面和用于盘轴的安装件。 磁盘具有摩擦表面,具有销负载边缘的孔,保持鲍登电缆端的鲍登电缆线座和由壳体中的支架支撑的轴。 盘和壳体的摩擦表面彼此接合以制动致动器和人体工程学支撑件。 具有销的杠杆设置在壳体上,使得销延伸穿过销槽以接合盘中的孔。 转动杆解除摩擦表面并旋转盘片,从而移动符合人体工程学的支架。 释放杆接合摩擦表面,使得符合人体工程学的支撑件的运动在选定位置制动。

    • A control rod drive mechanism includes a first tubular member having a first threaded portion and a first generally cylindrical outer surface, the first tubular member including a first plurality of slots spaced circumferentially on the first outer surface and extending in a direction parallel to the axis of the first tubular member, and a second tubular member having a second threaded portion and a second generally cylindrical outer surface, the second tubular member including a second plurality of slots spaced circumferentially on the second outer surface and extending in a direction parallel to the axis of the second tubular member. The first and second tubular members are axial aligned with the first and second threaded portions being engaged with each other to form a threaded joint therebetween. A locking sleeve overlaps at least a portion of the first outer surface of the first tubular member and at least a portion of the second outer surface of the second tubular member. The sleeve includes a generally cylindrical interior wall with deformed portions of the wall extending into said first and second plurality of slots. The deformed portions of the wall conform to an internal surface of each of the slots to evenly distribute circumferential loads on the locking sleeve. The invention also encompasses the method of assembling the control rod drive mechanism.
