    Abstract: A door guard for a swingable door that is mounted in a doorway having a door closer affixed to the doorway permits the door to open beyond the point which would normally be the widest open position allowed by the door closer and slows the rate of movement of the door so as to prevent damage to the door, door closer, or doorway. The door guard includes a flexible resilient arm extending transversely across the inside of the door and connected to the door closer at a point intermediate its ends, said arm is anchored at its inner end to the door and has its outer end releasably attached to the door, and catch means mounted on the door for releasably attaching the outer end of the arm to the door. When a force such as a gust of wind causes the door to fly open, such that the door closer reaches its fully extended position, the outer end of the arm is released by the catch means and the arm flexes to permit the door to continue opening. The further opening of the door is slowed by the resistance of the arm to flexing thus preventing damage to the door, door closer or doorway. The resistance may be provided by the inherent resiliency of the arm itself or by some other resilient member, such as a coil spring secured between the arm and the door.

    Abstract translation: 安装在具有门密封件的门口上的可摆动门的门把手允许门打开超过通常是由门关闭器允许的最宽敞开位置的点，并且减慢了门的移动速度 门，以防止损坏门，门关闭或门口。 门防护件包括横向穿过门内部延伸的柔性弹性臂，并且在其端部之间的一点处连接到门关闭器，所述臂在其内端锚定到门并且其外端可释放地附接到门 以及安装在门上的抓取装置，用于可释放地将臂的外端附接到门。 当诸如阵风的力导致门飞开时，使得门关闭器到达其完全伸出的位置，臂的外端由捕获装置释放，并且臂弯曲以允许门继续打开 。 门的进一步打开由于手臂挠曲的阻力而减慢，从而防止对门，门关闭或门口的损坏。 电阻可以由臂本身或其他弹性构件的固有弹性提供，例如固定在臂和门之间的螺旋弹簧。

    Abstract: Disclosed herein is a modular energy storage unit comprising one or more power packs that comprise one or more supercapacitors. The one or more power packs may be coupled together in series or parallel and connected with charging hardware. The energy storage unit is associated with an energy control system that manages the charging and discharging of the power packs as the energy storage unit power a device such as an electric vehicle and when the energy storage unit is being charged. In related aspects, the energy storage unit receives charge from solar cells or other alternative energy sources, and charging of the power packs is managed according to a database of information about the individual power packs in the energy storage unit to individually delivery of charge to each power pack to optimize the overall performance of the energy storage unit.
