Abstract: A controller assembly for a window blind includes a drive mechanism and at least one transmission mechanism with a gear unit and a transmission unit. When the gear unit is driven by the drive mechanism to operate, first and second major gears thereof rotate in two opposite rotational directions. The transmission unit is selectively coupled to rotate with a selected one of the first and second major gears. When the transmission unit is coupled to rotate with one of the first and second major gears, the window blind is driven to wind up. When the transmission unit is coupled to rotate with the other one of the first and second major gears, the window blind is driven to wind down.

Abstract: A Capacitive Micromachined Ultrasonic Transducer (CMUT) having a membrane operatively connected to a top electrode and having a bottom electrode having a concave void. When a DC bias voltage is applied, the membrane is deflected towards the bottom electrode such that a peripheral edge region of the membrane is brought into close proximity with the bottom electrode and an electrostatic force proximal to the peripheral edge region of the membrane is increased.

Abstract: A control device for coupling with a shaft of a window blind and controlling rotation of the shaft includes first and second ratchet seats, a spool assembly operable to rotate in unwinding and winding directions, a tubular case, an output unit coupled with the shaft, and a transmission unit operable to be shifted between a transmitting state to have a torque transmitted to the output unit, and a non-transmitting state to interrupt the torque transmission. Each ratchet seat has a surrounding groove and teeth. Balls are rollably engaged in the surrounding groove and the spool assembly for permitting rotation of the first ratchet seat with the spool assembly in the unwinding direction, and not to rotate the first ratchet seat in the winding direction.

Abstract: An auto-focusing device for solar heat energy power generators includes a stationary heating unit for absorbing solar energy to make works, a lens unit including a lens and a frame, a first driving unit connected to the frame and driving the frame, and a tracking unit electrically connected to the first driving unit and controlling the first driving unit to output power. The lens is fixed to the frame and focuses solar beam on the heating unit. The frame is movable along a curved track such that the lens always aims at the sun. Multiple auto-focusing devices for solar heat energy power generators are arranged in matrix form so as to generate electric power.

Abstract: A controller assembly includes a housing, first and second tube units, and first and second runners. Each of the first and second runners slides on a respective one of the first and second tube units when the respective one of the first and second tube units is driven to rotate. In response to sliding of the first runner to bring the first runner into abutment with the second runner, the first runner is prevented from sliding over the second runner, whilst impeding rotation of the first tube unit. In response to sliding of the second runner to bring the second runner into abutment with the first runner, the second runner is prevented from sliding over the first runner, whilst impeding rotation of the second tube unit.

Abstract: A control apparatus for controlling rotation of a shaft about an axis includes a roller releasably and rotatably connected to a rear housing mount of a housing that is firmly secured to a wall, an operating cord looped on the roller, a front coupling member co-rotatably coupled with the shaft, and a rear coupling member releasably connected to the roller by a rearward resilient force of a resilient member and movable and non-rotatable relative to the front coupling member. The roller is moved, upon an excess downward pulling force, to a releasing position, where the rear coupling member is moved forwardly to release connection with the roller so as to permit removal of the roller from the housing.
