    • An external sound system for a portable electronic device includes a mount configured to be secured to the portable electronic device, at least one sound panel coupled to the mount to selectively move between storage and operational positions relative to the portable electronic device, and at least one flat panel loudspeaker. The flat panel loudspeaker forms a portion of an exterior surface of the sound panel and is operably coupled to the portable electronic device to selectively produce sound. The sound panel can include a frame. The flat panel loudspeaker can include a vibratable panel having inner and outer surfaces, an exciter fixed to the frame and coupled to the inner surface of the vibratable panel to selectively impart vibrations to the vibratable panel, and a flexible support sheet secured to the outer surface of the vibratable panel and coupled to the frame to partially support the vibratable panel.
    • 用于便携式电子设备的外部音响系统包括被配置为固定到便携式电子设备的安装件,耦合到安装件的至少一个声音面板以选择性地相对于便携式电子设备在存储和操作位置之间移动,以及至少一个 平板扬声器 平板扬声器形成声音面板的外表面的一部分,并且可操作地耦合到便携式电子设备以选择性地产生声音。 声音面板可以包括一个框架。 平板扬声器可以包括具有内表面和外表面的可振动面板,激励器固定到框架并且联接到可振动面板的内表面以选择性地向可振动面板施加振动,以及柔性支撑片固定到外表面 并且联接到框架以部分地支撑可振动面板。

    • A keyless locking system for a cart includes a lock mechanism with a drive mechanism in the form of a solenoid that is electrically coupled to an integrated circuit and a long lasting power supply. In an unenergized state, an armature of the solenoid prevents operation of the lock mechanism to release drawers supported by the cart. Upon entry of a correct access code via a keypad associated with the integrated circuit, current is supplied to the solenoid to permit operation of the lock mechanism and thereby release the drawers. Advantageously, the lock mechanism only draws from the power supply to temporarily release the solenoid only thereby requiring minimal power and significantly reducing the re-charging, replacement and maintenance requirements for the power supply and the down time for the cart.
    • 用于推车的无钥匙锁定系统包括锁定机构,其具有螺线管形式的驱动机构,其被电耦合到集成电路和持久电源。 在未通电状态下,螺线管的电枢防止锁定机构的操作释放由推车支撑的抽屉。 当通过与集成电路相关联的键盘输入正确的访问代码时,电流被提供给螺线管,以允许锁定机构的操作,从而释放抽屉。 有利地,锁定机构仅从电源抽出以临时释放螺线管,从而需要最小的功率并且显着地减少电源的重新充电,更换和维护要求以及推车的停机时间。
