    • A wrist rest apparatus for supporting a user's wrist while receiving a manicure and holding the user's hand in a desired manner for the manicure. The wrist rest apparatus comprises a top console rotatably attached to a bottom console. The top console and the bottom consoles are defined by a solid plastic, semi-circular member having centrally disposed apertures in corresponding locations. The top console and the bottom console are joined together through a swivel member which is configured to pass through and be retained in the apertures, providing an axis about which the top console can rotate relative to the bottom console. Rotating locking mechanisms are included to allow rotation to be limited, with the top console being fixed in a parallel orientation relative to the bottom console.
    • 一种用于在接受修指甲的同时支撑使用者的手腕并且以所需的方式使用者的手握住修指甲的腕托装置。 腕部装置包括可旋转地附接到底部控制台的顶部控制台。 顶部控制台和底部控制台由固定的塑料半圆形部件限定,在对应位置具有中心设置的孔。 顶部控制台和底部控制台通过旋转构件连接在一起,旋转构件被构造成穿过并保持在孔中,提供了顶部控制台相对于底部控制台可旋转的轴线。 包括旋转锁定机构以允许限制旋转,顶部控制台相对于底部控制台以平行方向固定。

    • An emergency control system for selectively activating and deactivating an apparatus. The system includes a fiber optic transmitter for emitting radiation and a fiber optic receiver for receiving and measuring a wavelength and an intensity of the radiation. A manually-operated fiber optic switch is placed in optical communication with the fiber optic transmitter and the fiber optic receiver. In operation, the switch is selectively actuated, thereby selectively opening and closing a fiber optic circuit defined by the transmitter, receiver, and the switch. The system further includes a relay controller in communication with the fiber optic receiver, such that the relay controller is actuated when the fiber optic receiver receives a predetermined wavelength and intensity of radiation from the transmitter. When the relay controller is actuated, it allows a signal to pass through the relay to a point of use. In this manner, the operation of the fiber optic switch selectively controls the presence of the signal at the point of use, which can be a spring loaded solenoid valve or other electromechanical actuator capable of deactivating an apparatus.
    • 一种用于选择性地启动和停用装置的应急控制系统。 该系统包括用于发射辐射的光纤发射器和用于接收和测量辐射的波长和强度的光纤接收器。 手动操作的光纤开关与光纤发射器和光纤接收器进行光通信。 在操作中,选择性地启动开关,从而选择性地打开和关闭由发射器,接收器和开关限定的光纤电路。 该系统还包括与光纤接收器通信的继电器控制器,使得当光纤接收器接收到来自发射器的预定波长和辐射强度时,继电器控制器被致动。 当继电器控制器被启动时,它允许信号通过继电器到使用点。 以这种方式,光纤开关的操作选择性地控制在使用点处的信号的存在,其可以是弹簧加载的电磁阀或能够停用装置的其它机电致动器。
