    • A repeater for enhancing performance of a TDMA mobile radio system in poor signal areas has a bank of frequency agile, single channel amplifiers (13), and controller (14). The controller (14) scans the channel of the band and, upon identifying a channel carrying traffic, enables one of the amplifier units (13) to operate on that channel. Each of the amplifier units (13) includes a time slot activity detector (35) for detecting which time slot of a channel is active. The output of the activity detector (35) is passed to a logic control module (36), which controls the amplification of an active time slot via a time slot gate and power unit (38).

    • Wheel balancers and methods of their use are disclosed. One wheel balancer includes a cable and a base. The cable has a support end for being fastened to a support. The base is configured for receipt inside a wheel, and the base has proximal and distal ends and a hollow interior area for passing the cable therethrough. The cable passes through the base interior area and is operatively coupled to the base such that a distance between the cable support end and the base distal end is generally constant when the cable is extended. A pivot point for the cable is movable relative to the base between the base distal end and the cable support end.
    • 公开了车轮平衡器及其使用方法。 一个平衡器包括电缆和底座。 电缆具有用于紧固到支撑件的支撑端。 底座构造成用于容纳在车轮内部,并且底座具有近端和远端以及用于使电缆穿过其的中空内部区域。 电缆穿过基部内部区域并且可操作地联接到基部,使得当电缆延伸时,电缆支撑端和基部远端之间的距离通常是恒定的。 电缆的枢转点可相对于基部远端和电缆支撑端之间的基座移动。

    • Push-pull controls utilizing linear and rotational inputs to create linear output are disclosed. One control includes an elongate push rod and a roller pin. The rod has an outer surface, a generally circular cross-section perimeter, a center axis, a proximal end with a user input, and a distal end configured to directly or indirectly interact with an apparatus to be controlled. The rod is rotatable and slidable along the rod axis. The roller pin has a center axis and an outer surface that contacts the push rod outer surface. The roller pin center axis is angularly offset from and non-intersecting with the push rod center axis. The amount of angular offset is greater than zero degrees.
    • 公开了利用线性和旋转输入来产生线性输出的推挽控制。 一个控制器包括细长的推杆和滚针。 杆具有外表面,大致圆形的横截面周长,中心轴线,具有使用者输入的近端,以及配置为直接或间接地与要控制的装置相互作用的远端。 杆可旋转并可沿杆轴滑动。 滚针具有中心轴线和与推杆外表面接触的外表面。 滚针中心轴与推杆中心轴成角度偏移并与之不相交。 角度偏移量大于零度。
