Abstract: An electronic device with a fan assembly is disclosed. The fan assembly includes an impeller and an insert separated from the impeller by a gap. The fan assembly increases airflow by rotationally driving the impeller. For a sufficient rotational speed of the impeller, the airflow reaches a level that provides a force that displaces the insert. The displacement may include movement and/or compression of the insert. As a result of the displacement, the gap between the impeller and the insert increases. The increased gap reduces the pressure and associated noise that is otherwise caused by the airflow. When the rotational speed of the impeller reduces or ceases, the insert returns to its initial position. In this manner, the fan assembly includes a self-adjusting gap that changes based on the airflow.

Abstract: A computer system that generates a disposition instruction and an associated access command directed to a block of data at a logical address is described. The disposition instruction and the access command are communicated to a memory system in the computer system via a communication link. Note that the memory system includes different types of memory having different performance characteristics, and the disposition instruction is generated based on the different performance characteristics. In response to the access command, the memory system accesses the block of data at the logical address in a first type of memory in the different types of memory. Furthermore, based on the disposition instruction, the memory system moves the block of data to a second type of memory in the different types of memory to facilitate subsequent accesses to the block of data.

Abstract: A fan motor suitable for use in an electronic device, such as a consumer electronic device, is disclosed. The fan motor includes a stator and a rotor. In order to minimize a varying torque applied to the rotor, the stator includes modifications. For example, the stator includes stator teeth, each with an arc defined by a radius of curvature that varies. The radius (from a reference point to the arc) can vary in accordance with a sinusoidal curve. Furthermore, the corners of each stator tooth may be rounded. The rounded corners of the stator teeth may include a uniform (or constant, non-varying) radius of curvature. These enhancement are designed to provide a more uniform torque by the stator to the rotor. As a result, the rotation of the rotor is subject to smaller fluctuations, and the fan motor undergoes less vibration and generates less acoustical noise.

Abstract: Portable computer structures are provided. The portable computer structures may include hard drive mounting structures. The hard drive mounting structures may include elastomeric support members. Each elastomeric support member may have a relatively rigid inner portion. The inner portion may include a hole that receives a hard drive mounting pin. Each elastomeric support member may also have a relatively flexible outer portion. The relatively flexible outer portion may be mounted within an opening in a plastic support member. The rigid inner portion may have a square outline and may be mounted within a square opening in the flexible outer portion.
