摘要： A computer controlled subjective refractor includes a microcomputer based remote hand control connected to an enclosure which houses the optical elements of the refractor and which controls their operation for the examination of a patient. The enclosure has a beam splitter extending at its bottom and a forehead rest extending near its bottom such that a patient's eyes are positioned near the bottom of the enclosure to view into the beam splitter and thereby materially reduce accommodation which would otherwise interfere with the accurate refracting of the patient's eyes. Movement and position location of the optical elements are achieved through a microcomputer based electronic controller which is in communication with the microcomputer remote hand control. Additionally, a microcomputer based target projector assembly may be used to selectively project any of a wide number of images comprised of eye charts and the like for testing the patient's vision. The subjective refractor thereby provides a network of microcomputer based electronic controls for very accurately positioning a plurality of optical elements and determining their position in order to determine the refractive correction of a patient's eyes. The handheld remote control includes an optical display and a number of finger controls through which an operator may actively interact with the subjective refractor as the patient is examined.
摘要翻译： 计算机控制的主观折射仪包括连接到容纳折射器的光学元件并且控制其用于检查患者的操作的外壳的基于微机的远程控制。 外壳具有在其底部延伸的分束器和在其底部附近延伸的前额支架，使得患者的眼睛位于靠近外壳的底部以观察分束器并且因此实质上减少适应，否则会干扰准确的折射 的病人的眼睛。 光学元件的移动和位置位置通过与微型计算机远程手控制通信的基于微机的电子控制器来实现。 此外，可以使用基于微机的目标投影仪组件来选择性地投影包括眼图等的大量图像中的任何一个，以便测试患者的视力。 因此，主观折射体提供了一种基于微机的电子控制网络，用于非常精确地定位多个光学元件并确定它们的位置，以便确定患者眼睛的屈光矫正。 手持遥控器包括光学显示器和多个手指控制器，当患者被检查时，操作者可以通过该手指控制器主动地与主观折射器相互作用。

摘要： A foot actuated wheel brake for shopping carts and other wheeled equipment is disclosed. The wheel brake is designed for at least one wheel in a wheeled cart where each wheel is rotatably supported on a yoke at a lower end of a leg support in the wheeled cart. The wheel brake includes a first foot pedal that extends above and is movably mounted to the yoke. Preferably, the first foot pedal has a red colored stop sign shape. A second foot pedal extends laterally outwardly beyond the yoke and is movably mounted to the first foot pedal. Preferably, the second foot pedal has a green colored curvilinear shaped element that extends outwardly beyond the red colored stop sign shape. Operating engaging/disengaging structure is associated with the first and second foot pedals for moving the brake shoe into braking engagement with the wheel when the first foot pedal is engaged and for releasing the brake shoe from the wheel when the second foot pedal is engaged. The foot actuated wheel brake of the present invention may be used on existing shopping carts as well as on original equipment.

摘要： A foot actuated wheel brake for shopping carts and other wheeled equipment is disclosed. The wheel brake is designed for at least one wheel in a wheeled cart where each wheel is rotatably supported on a yoke at a lower end of a leg support in the wheeled cart. The wheel brake includes a first foot pedal that extends above and is movably mounted to the yoke. Preferably, the first foot pedal has a red colored stop sign shape. A second foot pedal extends laterally outwardly beyond the yoke and is movably mounted to the first foot pedal. Preferably, the second foot pedal has a green colored non-stop sign shaped element that extends outwardly beyond the red colored stop sign shape. Operating engaging/disengaging structure is associated with the first and second foot pedals for moving the brake shoe into braking engagement with the wheel when the first foot pedal is engaged and for releasing the brake shoe from the wheel when the second foot pedal is engaged. For nesting of shopping carts, the first foot pedal is mounted on an angularly offset upper wall at the rear of the yoke below a substantially horizontally directed upper wall that is connected to a lower end of a shopping cart leg support. The second foot pedal extends laterally outwardly beyond and below the first foot pedal. The foot actuated wheel brake of the present invention may be used on existing shopping carts as well as on original equipment.
