    摘要: A load control device is adapted to be disposed in series with an AC voltage source and an electrical load and is operable to provide substantially all voltage provided by the AC voltage source to the load. The load control device comprises a controllably conductive device, a controller, a zero-crossing detector, and a power supply for generating a substantially DC voltage for powering the controller. The power supply is operable to charge an energy storage device to a predetermined amount of energy each half-cycle. The controller is operable to determine when the power supply has stopped charging from the zero-crossing detector each half-cycle, and to immediately render the controllably conductive device conductive to conduct the full load current. Before the controllably conductive device begins to conduct each half-cycle, only a minimal voltage develops across the power supply to allow the energy storage device to charge.

    摘要: A keyboard can be modified to facilitate use in a variety of applications such as, for example, gaming. Examples of modifications include, but are not limited to, placing a numeric keypad to the left of an alphanumeric keypad, having particular keys with a different color, changing the relative arrangement of keys, adding new keys, and moving functions to different sites on the keyboard.

    摘要: A multi-positional, multi-level user interface system including a keyboard hinged over a base surface for a pointing device such as a mouse. The keyboard and base rotate relative to each other about a hinge axis to reveal the surface, providing a portable keyboard and pointing surface. A kickstand can support the keyboard above the base while in an open position. The keyboard and pointing device can be used with two hands with the system resting in a user's lap. The keyboard can also swivel about an axis other than the hinge axis. The keyboard can swivel 180 degrees for left-handed use, and can be positioned at other detent angles. A mouse can also be stowed on the base with a magnetic, friction, or other coupling. The interface system can further act as a communication hub for other peripheral devices, such as a joystick, to communicate with a computing device.
