Abstract: A mirror device includes a frame body, a shaft member provided inside the frame body and connected to the frame body at both end portions, and a reflection member fixed to the shaft member and provided so as to be capable of swinging around an axis of the shaft member. The reflection member has a base portion provided along an axial direction of the shaft member and a reflection portion provided on the base portion. The base portion has a three-dimensional uneven structure including a bottom wall portion having a main surface provided along the axial direction of the shaft member and a plurality of side wall portions extending from the bottom wall portion on the side opposite to the reflection portion.

Abstract: 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.

Abstract: 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.

Abstract: Embodiments are disclosed that relate to implementing semiconductor device cooling systems that leverage awareness of regional voltage and temperature reliability risk considerations. For example, one disclosed embodiment provides a method of implementing a cooling system configured to cool an integrated circuit. The method involves first determining a heat dissipation factor that would reduce each region of the integrated circuit to a reduced temperature in order to maintain an overall failure rate. An analysis is then performed, using an insight about the relative reliability risk of elevated voltage and temperatures, to identify a region of the integrated circuit whose temperature can be permitted to rise without exceeding the overall failure rate, thereby permitting implementation of a cooling system with a reduced heat dissipation factor.

Abstract: 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.
