摘要： A biax gimballing arrangement permitting both axes of rotation to intersect at a point within a load being gimbaled, thereby permitting the rotational inertia of the load and the gimbal mechanism itself to be minimized. Gimbal rotation about a first axis is achieved by a first drive motor. Rotation in a second axis orthogonal to the first axis is achieved by a steel cable drive assembly having two drive cable ends that are passed through the first rotational axis on their way to respective anchor points within a portion of the gimbal apparatus that is rotated about the first axis. This rotatable portion of the gimbal apparatus includes milled guideways which permit rotation of the gimbal load mount. The central portion of the cable is driven by engagement with a pulley attached to the shaft of a second drive motor.

摘要： An optical-input print reading device with voice output for people with impaired or no vision in which the user provides input to the system from hand gestures. Images of the text to be read, on which the user performs finger- and hand-based gestural commands, are input to a computer, which decodes the text images into their symbolic meanings through optical character recognition, and further tracks the location and movement of the hand and fingers in order to interpret the gestural movements into their command meaning. In order to allow the user to select text and align printed material, feedback is provided to the user through audible and tactile means. Through a speech synthesizer, the text is spoken audibly. For users with residual vision, visual feedback of magnified and image enhanced text is provided. Multiple cameras of the same or different field of view can improve performance. In addition, alternative device configurations allow portable operation, including the use of cameras located on worn platforms, such as eyeglasses, or on a fingertip system. The use of gestural commands is natural, allowing for rapid training and ease of use. The device also has application as an aid in learning to read, and for data input and image capture for home and business uses.
摘要翻译：一种光学输入打印读取装置，其具有用于受损或无视觉的人的语音输出，其中用户通过手势向系统提供输入。将用户执行基于手指和手势的手势命令的要读取的文本的图像输入到计算机，计算机通过光学字符识别将文本图像解码为其符号意义，并进一步跟踪位置和移动手和手指为了将手势运动解释成他们的命令意义。为了允许用户选择文本并对齐印刷材料，通过可听和触觉的方式向用户提供反馈。通过语音合成器，文本可听到。对于具有残余视力的用户，提供了放大和图像增强文本的视觉反馈。相同或不同视野的多个摄像机可以提高性能。此外，替代的设备配置允许便携式操作，包括使用位于佩戴的平台上的相机，例如眼镜或指尖系统。使用手势命令是自然的，允许快速的训练和易于使用。该设备还具有应用程序，以帮助学习阅读，以及用于家庭和商业用途的数据输入和图像捕获。

摘要： A system is disclosed for moving a load from an equilibrium position to which it is urged by extraneous forces, with reduced power required of the motive system. In the system, a load is engaged by means storing potential energy when the load is in its equilibrium position and returning the potential energy to the load as it is moved from the equilibrium position. Such a nozzle-actuating system includes generally a frame, an electric motor drive, and a member, driven by the electric motor drive, that is movably carried by the frame and connected with the rocket nozzle. The frame and driven member can include a cam and spring arrangement to provide a force counteracting the force imposed on the driven member by the rocket nozzle when it is displaced from its normal position by the electric motor drive.

摘要： A compass device for underwater use and having substantially no magnetic nature or influence utilizes three Hall effect generators in an array wherein two of the generators have their principal axes of magnetic response extending normal to one another and at 45.degree. to the axis of the third generator. The array is rotatable relative to a base carrying three lights and solid state analog logic circuitry for causing the lights to be variously lighted and extinguished to indicate a need to turn left, to turn right, or being on course.
