Abstract: A device for controlling the pitch of a helicopter's rotor blade, the device having a BLDC motor based actuator; and at least one control surface operatively connected to the BLDC motor based actuator. The actuator and the control surface are preferably fully integrated into the interior profile of the rotor blade and are capable of controlling the PFC of the helicopter and improving HHC during operation by reducing noise and vibration. The motor is preferably a high power density motor incorporating rare earth permanent magnets connected to a roller/ball screw or planetary gear set to provide the right combination of force/torque, stroke and frequency.

Abstract: A method for fabricating a semiconductor device is disclosed. A first substrate is arranged over a second substrate. A wafer bonding process is performed on the semiconductor device. First regions of the device are enclosed by the bonding process. Second regions of the device remain exposed. One or more processes are performed on the exposed second regions, after performing the wafer bonding process. The one or more processes include a fill process that forms a fill material within the exposed second regions. An edge seal material is applied on the first and second substrates after performing the one or more processes.

Abstract: The present invention provides a heat-dissipating device and a method for manufacturing the same. The heat-dissipating device includes a heat sink and a heat pipe. The heat sink has an end surface provided with a groove. The heat pipe is received in the groove. The heat pipe has a heat-absorbing surface and a heat-conducting surface. The heat-conducting surface is adhered to the inner edge of the groove. The heat-absorbing surface is in flush with the end surface. With this arrangement, heat resistance of the heat-dissipating device is reduced to improve the heat-dissipating effect thereof.
