摘要： Particular embodiments described herein provide for an electronic device that includes a fan. The fan can include a center shaft, fan blades that extend from the center shaft, and a plurality of magnets on an outside portion of at least two of the fan blades, where stator coils interact with the magnets to drive the blades around the center shaft. The center shaft and fan blades are a single component from the same material. In some examples, the center shaft and fan blades were created using a metal injection molding process.

摘要： Illustrative examples include a system for coupling a first electronic device to a second electronic device. The first electronic device may include a housing having a first engagement surface and a first magnet array. The first engagement surface may be adapted to receive the second electronic device. The second electronic device may include a second magnet array. An actuator coupled to the first magnet array may move the first magnet array relative to the housing and the second magnetic array, to attractively couple or repulsively de-couple the second electronic device from the first electronic device.
