    • A user-powered apparatus, system, and method of providing a pedestrian with information is disclosed. The present invention harvests energy created by a moving pedestrian and takes the harvested energy and uses it to recharge an energy storage device that is embedded in the same footwear. Also built into the footwear may be a microcontroller and sensor, and a transmitter/receiver mechanism by which signals may be transmitted to and received from a wrist watch, iPod®, cell phone and/or any similar portable device on the pedestrian. The footwear may be capable of receiving signals transmitted by the portable device or GPS satellite. The GPS satellite may provide information about the geographical location of the pedestrian. Since the energy storage device may be flexible, it can survive on footwear that gets flexed a significant amount. The energy harvester may harvest energy from the footsteps of the pedestrian or some other source and recharge the energy storage device so that there is no need to replace the energy storage device that is an integral and inseparable part of the footwear.
    • 公开了一种向行人提供信息的用户供电设备,系统和方法。 本发明收获由移动的行人产生的能量,并且采集收获的能量并使用它来对嵌入同一鞋类的能量存储装置进行再充电。 鞋内还可以是微控制器和传感器,以及发送器/接收器机构,通过该机构可以向手表,iPod,手机和/或行人上的任何类似的便携式装置发送和接收信号。 鞋类可以能够接收由便携式设备或GPS卫星发送的信号。 GPS卫星可以提供关于行人的地理位置的信息。 由于能量储存装置可能是柔性的,所以它可以在大量弯曲的鞋类上存活。 能量收集器可以从行人或其他来源的脚步中收获能量,并对能量存储装置进行再充电,从而不需要更换作为鞋类的整体和不可分离部分的能量存储装置。

    • Described herein is, for example, a battery or capacitor over voltage (overcharge) and under-voltage protection circuit, that, for example, is adapted to not draw current from the battery or capacitor to be charged unless charge energy is detected and to not charge an energy storage device when an over-charge condition is sensed. The protection circuit may, for example, not be turned on unless an over voltage condition is present. Incoming energy to the system can be shunted to ground via a shunt load of various types including resistive loads and active components such as a zener diode. In some embodiments, no switching of the inbound power is required. Within limits, no regulation of inbound power is needed. When inbound power is sufficient to charge the battery or capacitor, regulation can occur via the applied shunt regulator if overcharge voltage conditions exist. Either type of charge source, voltage or current, can be used to provide charge energy. Combining said battery or capacitor over voltage (overcharge) and under-voltage protection circuit with electronic loads, such as wireless sensors, may lead to autonomously-powered wireless sensor systems.
    • 这里描述的是例如电池或电容器过电压(欠充电)和欠压保护电路,其例如适于不从要被充电的电池或电容器中抽出电流,除非检测到充电能量,而不是 当检测到过充电状态时,对能量存储装置充电。 除非存在过电压状态,否则保护电路可以例如不被接通。 通过各种类型的并联负载(例如电阻负载和诸如齐纳二极管的有源组件),能将系统的输入电能分流到地。 在一些实施例中,不需要对入局功率进行切换。 在限制范围内,不需要调节入站电力。 当入站电力足以对电池或电容器充电时,如果存在过充电电压条件,则可通过施加的分流调节器进行调节。 可以使用任何一种类型的电荷源,电压或电流来提供电荷能量。 将所述电池或电容器过电压(过充电)和欠电压保护电路与诸如无线传感器的电子负载组合可能导致自主供电的无线传感器系统。

    • A power unit for attachment to scaffolding towers such as commonly used for overhead work in the installation of wiring, ductwork, painting, and finishing. A single power unit attached to one leg of a scaffolding tower can move, about the worksite, a large scaffolding tower assembly comprised of one or more individual scaffolding towers. Two power units working in tandem on separate legs of the scaffolding tower assemblage, provides increased maneuverability. Each power unit has separate motors to drive and to change the direction of a scaffolding tower assembly. One electric motor pivots the power unit about the scaffolding tower leg to which it is attached, thereby changing the direction of motion of the scaffolding tower assembly. Another electric motor of the power unit provides power to a drive wheel of the power unit, and consequently moves the scaffolding tower assembly. A brake prevents rotation of the drive wheel when the power unit is not in operation, thereby keeping the scaffolding tower assembly in one location. A clutch within the drive wheel mounting allows the scaffolding to be manually freewheeled about without interference from the scaffolding power unit. A power cord and an electrical control cable with a control console may be extended to any length for remote control of the scaffolding power unit and when not in use may be coiled within the unit for convenient storage.
    • 用于连接到脚手架的电源单元,例如通常用于布线,管道系统,喷漆和整饰安装中的高架作业。 连接到脚手架塔的一条腿上的单个动力单元可在工地周围移动由一个或多个单独的脚手架塔组成的大型脚手架塔组件。 在脚手架塔组合的单独的腿上串联工作的两个动力单元提供了增加的机动性。 每个动力单元具有单独的电动机以驱动并改变脚手架塔组件的方向。 一个电动马达围绕其所附接的脚手架塔腿枢转动力单元,从而改变脚手架塔组件的运动方向。 动力单元的另一个电动马达向动力单元的驱动轮提供动力,从而移动脚手架塔组件。 当动力单元不工作时,制动器防止驱动轮旋转,从而将脚手架塔组件保持在一个位置。 驱动轮安装中的离合器允许脚手架在脚手架动力单元不受干扰的情况下手动自由旋转。 电源线和带控制台的电气控制电缆可以扩展到任何长度,用于远程控制脚手架电源单元,并且当不使用时可能卷绕在设备内以方便存储。
