摘要： A flapping fan for cooling electronic devices includes an elongated piezo actuator, two supporting members, two connecting members, and a thin blade. The supporting members are attached to the piezo actuator at its two ends, while the blade is connected to the piezo actuator through the connecting members. When activated by an AC signal, the piezo actuator oscillates around its neutral position, which causes the blade to oscillate. The blade rotates around its leading edge when its direction of motion changes, keeping its angle of incidence lower than ninety degrees. This helps the flapping fan to generate a significant air flow.

摘要： An electromagnetic cooling fan includes a thin blade connected to an elongated beam. The beam is simply supported at its two ends with two supporting members. The beam has a magnet attached to it at the center. An electromagnet is used to generate cyclic force on the magnet, causing the beam and the blade to oscillate, generating air flow for cooling purpose.

摘要： A flapping fan for cooling electronic devices includes an elongated piezo actuator, two supporting members, two connecting members, and a thin blade. The supporting members are attached to the piezo actuator at its two ends, while the blade is connected to the piezo actuator through the connecting members. When activated by an AC signal, the piezo actuator oscillates around its neutral position, which causes the blade to oscillate. The blade rotates around its leading edge when its direction of motion changes, keeping its angle of incidence lower than ninety degrees. This helps the flapping fan to generate a significant axial air flow.

摘要： A device for engaging and tensioning a glass ribbon includes a center frame member, and first and second outer frame members connected thereto. The first outer frame member includes a suction cup that engages an edge area of the glass ribbon and an actuator for moving the suction cup of the first outer frame member. The second outer frame member includes a suction cup that engages an opposite edge area of the glass ribbon and an actuator for moving the suction cup of the second outer frame member. The actuators of the first and second outer frame members moves the suction cups of the respective frame members in directions away from each other.
