    • 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。

    • Method and apparatus for a range hood. The apparatus can include a housing and a lighting and control unit moveably coupled to the housing. The lighting and control unit can include a user interface and one or more lights. The lighting and control unit can be coupled to a motor that can move a first face of the lighting and control unit outward during use and can move the first face of the lighting and control unit inward when not in use. Some embodiments of the invention provide a fan mounted within the housing and a louver assembly coupled to the housing. The louver assembly can include one or more rotating louvers. In some embodiments, the louver assembly can be rotated downward to access at least one of a filter, a motor, and user interface electronics.
    • 抽油烟机的方法和设备 该装置可以包括壳体和可移动地联接到壳体的照明和控制单元。 照明和控制单元可以包括用户界面和一个或多个灯。 照明和控制单元可以耦合到电动机,其可以在使用期间将照明和控制单元的第一面向外移动,并且可以在不使用时将照明和控制单元的第一面向内移动。 本发明的一些实施例提供了安装在壳体内的风扇和联接到壳体的百叶窗组件。 百叶窗组件可以包括一个或多个旋转百叶窗。 在一些实施例中,百叶窗组件可以向下旋转以接近过滤器,马达和用户界面电子器件中的至少一个。
