    • An apparatus for grinding a mineral includes a head operable to be attached to a bottle. The head includes a radial slider for controlling the coarseness of the grind. The apparatus further includes an inner grinding element, an outer grinding element, a shaft, and a neck sleeve. The inner grinding element is in communication with the head. The outer grinding element is also in communication with the head, wherein the outer grinding element and the inner grinding element are operable to rotate relative to each other. The shaft extends through the inner grinding element and the outer grinding element. The shaft couples with the inner grinding element and comprises a blunt end. The shaft also extends through the neck sleeve, which acts as a spacer between the inner grinding element and the blunt end.

    • A solar-powered automated system for the operation of drapery, roller blinds, and similar window coverings. The solar panel (102), or photovoltaic source provides the sole power to drive common types of window drapery and blinds in a compact system having a solar panel (photovoltaic source), actuator (104) and head rail (120). The solar panel (102) is to be mounted onto the frame of a window or elsewhere to collect sufficient light. A connecting cable links the solar panel (102) to the actuator (104) to draw electrical power from the solar panel. The actuator is attached to the head-rail (120) to provide the required driving force. The actuator (104) includes the control circuit boards, a single rechargeable battery (110), an electric motor (106) and output mechanism. An RF remote control receiver (116) is built inside the actuator (104). A low voltage control port (114) allows the actuator (104) to be accessible by a control interface. The control circuit comprises a standby circuit (111) and a boosting circuit (108). The standby circuit (111) operates at the battery voltage level and consumes minimum power to save energy when the system is not in use. The boosting circuit (108) is only activated when the actuator (104) drives the window covering, and works only during the time span of such activity. The head rail (120) houses the necessary members for transmitting the driving force to the drapery for open/close operation. It can also be a rotary type for a roller blind.
    • 一种用于操作帷幔,百叶窗和类似窗帘的太阳能自动化系统。 太阳能电池板(102)或光伏源提供了在具有太阳能电池板(光伏源),致动器(104)和头轨(120)的紧凑系统中驱动通用类型的窗帘和百叶窗的唯一功率。 太阳能电池板(102)将被安装在窗户或其他地方的框架上以收集足够的光。 连接电缆将太阳能电池板(102)连接到致动器(104)以从太阳能电池板吸取电力。 致动器附接到头轨(120)以提供所需的驱动力。 致动器(104)包括控制电路板,单个可再充电电池(110),电动机(106)和输出机构。 一个RF遥控接收器(116)被构建在致动器(104)的内部。 低压控制端口(114)允许致动器(104)由控制接口访问。 控制电路包括备用电路(111)和升压电路(108)。 备用电路(111)以电池电压电平工作,并且在系统不使用时消耗最小功率以节省能量。 升压电路(108)仅在致动器(104)驱动窗户覆盖件时被激活,并且仅在这种活动的时间间隔内才起作用。 头轨(120)容纳用于将驱动力传送到窗帘以进行打开/关闭操作的必要部件。 它也可以是用于卷帘的旋转式。
