    • In a moving craft connected by a towline to an ejected and freely falling object, a brake control system determines when to engage a brake that accelerates the object to the moving craft's speed by retarding the deployment of the towline without exceeding its rated working load. The control system continually monitors the velocity and the total deployed distance of the ejected object. When a point in a velocity-distance state-space plane corresponding to the monitored velocity and the monitored total deployed distance of the ejected object has reached a switching curve (48), the control system actuates a brake (74). The switching curve (48) is the locus of intersection points (38, 40, 42, and 44) of a plurality of pairs of curves, each pair consisting of a free-fall trajectory (23, 24, 26, and 28) and a brake trajectory (30, 32, 34, and 36) and being associated with a different craft velocity. The free-fall trajectory is the trajectory that the object follows after it has been ejected from the craft and is falling away from the craft under the influence of drag. The brake trajectory is the trajectory by which the brake system causes the object to stop at the desired deployment distance.
    • 在通过拖链连接到被弹出和自由落下的物体的移动工艺中,制动控制系统确定何时接合制动器,以通过延迟拖曳部分而不超过其额定工作负荷来加速物体与移动工艺的速度。 控制系统持续监控喷射物体的速度和总部署距离。 当对应于所监视的速度的速度距离状态空间平面中的点和被喷射物体的被监视的总部署距离达到切换曲线(48)时,控制系统致动制动器(74)。 切换曲线(48)是多对曲线的交点(38,40,42和44)的轨迹,每对曲线由自由落体轨迹(23,24,26和28)和 制动轨迹(30,32,34和36)并且与不同的飞行速度相关联。 自由落体的轨迹是物体在从工艺中弹出并在拖动的影响下从工艺上掉下来的轨迹。 制动轨迹是制动系统导致物体在所需部署距离处停止的轨迹。

    • A method and device for unclogging a drain assembly by creating an airtight, watertight seal in the drain assembly. An overflow cover device functions to form a complete seal in the drain assembly, such that no air and water pressure is lost throughout the drain assembly while a plunging device creates pressure and a vacuum over a drain opening. The water pressure generated by the plunging device is maximized to remove a clog in the drain assembly. The overflow cover device includes a front surface, and a mounting surface. The mounting surface includes a cover seal on the peripheral edge for inhibiting the escape of air and water. The mounting surface engages the overflow opening, and secures into place through machine screws that pass through one or two holes in the overflow cover device.

    • An optically guided munition and control system has a replacement fuse assembly mounted on the front of a munition body or shell casing. An optical seeker subsystem detects an illuminated target and supplies signals to a processor. The processor develops steering commands sent to a flight control subsystem having a plurality of guidance canards which are actuated by drive motors through gear assemblies. The roll of the munition is established and left/right and up/down steering commands are sent to the canard drive motors based upon the optical seeker subsystem detection of the target illuminator. Range adjustment is based upon bore sight lockdown angle and cross range control is based upon left/right centering error. A code is contained in the optical radiation received from the illuminated target which must be validated by a preset code in the system processor to arm the munition.

    • A system and method for testing components traveling at high speeds is presented. A system includes an elongated test chamber, high and low pressure reservoirs, a piston and a pressure control system. The elongated test chamber has first and second ends. In some configurations, the test chamber can be a pneumatic cylinder. The high pressure reservoir is connected to the first end of the elongated test chamber and the low pressure reservoir is connected to the second end of the elongated test chamber. The piston travels with a unit under test from the first end of the test chamber to the second end of the test chamber. The pressure control system uses, in part, the low and high pressure reservoirs to dynamically adjust a force profile across the piston as it travels from the first end of the elongated test chamber to the second end of the elongated test chamber.
