Abstract: Support foot apparatus that include a support foot structure that employs flexible flap members disposed on opposing sides of a central foot member, and that are configured for insertion into corresponding openings of a support foot location defined in an exterior surface of the chassis of an information handling system or other device or structure. Each of the flexible flap members may be provided with one or more securing apertures configured for placement over corresponding securing posts provided on an interior surface of the chassis to secure the flexible flap members of the support foot apparatus within the interior of the chassis at a support foot location to hold the central support body against an exterior surface of the chassis.

Abstract: The present invention provides a fan including a stator and a rotor coupled to the stator. The stator has a base and a bearing disposed inside the base. The rotor has a shaft supported by the bearing. Furthermore, the shaft has a concave structure formed on a surface thereof, or the bearing has a groove structure formed on a surface thereof.

Abstract: Apparatus and methods for placement of battery packs in portable information handling systems such as notebook and netbook computers. A first set of pivot features may be provided on opposing sidewalls of a battery well that interface with a corresponding set of mating pivot features provided on exterior end surfaces of a battery pack such that the battery pack may be pivoted into and out from the battery well to install or release it from the system, e.g., pivoted from the bottom of the portable information handling system in a manner that does not interfere with, or require modification to, the lid and display of the portable information handling system. A latch mechanism and battery release feature may be further provided that acts to transfer horizontal manipulation (e.g., horizontal sliding motion) of the battery release feature to a vertical latching action that acts to lift the battery pack out from the portable information handling system chassis when releasing the battery pack from the chassis.

Abstract: An information handling system (IHS) includes an IHS chassis having a processor and defining a battery housing. An IHS connector is located adjacent the battery housing and is electrically coupled to the processor. A battery is located in the battery housing and includes a battery chassis that houses at least one battery cell. A battery connector is electrically coupled to the at least one battery cell and engages the IHS connector. The battery connector is moveably coupled to the battery chassis through a battery connector coupling that allows the battery connector to move relative to the battery chassis when the battery connector engages the IHS connector.

Abstract: A method for manufacturing metal nano particles having a hollow structure is provided. First, a suitable reducing agent is added into a first metal salt solution, and first metal ions are reduced to form first metal nano particles. Next, after the reducing agent is decomposed, a second metal salt solution with a higher reduction potential than that of the first metal is added. Then, the first metal particles are oxidized to form first metal ions when the second metal ions are reduced on the surface of the first metal by electrochemical oxidation reduction reaction, and thus, second metal nano particles having a hollow structure and a larger surface area are obtained. The method is simple and the metal nano particles with uniform particle size are obtained by this method.

Abstract: A fan includes an impeller, a motor and a frame. The impeller has a hub and a plurality of blades disposed around the hub. The motor connects to the impeller and drives it to rotate. The frame accommodates the impeller and the motor therein. The material of the impeller, the motor or the frame includes a color-changeable material.

Abstract: A heat dissipation apparatus. A fan frame includes an air inlet, an air outlet, a passage, and a curved expansion portion. The air inlet is opposite the air outlet. The passage is between the air inlet and the air outlet, guiding airflow from the air inlet to the air outlet. The curved expansion portion is radially and outwardly extended from an inner peripheral wall of the passage at the air inlet or air outlet. An impeller is disposed in the fan frame and includes a plurality of blades. Each blade is disposed in the passage and includes an extension end extending to the curved expansion portion.

Abstract: A heat dissipation apparatus. A fan frame accommodates an impeller therein and includes an air inlet, an air outlet, and a passage for guiding airflow from the air inlet to the air outlet. An inner peripheral wall of the passage radially and outwardly extends a smooth curved expansion portion at the air outlet. The curved expansion portion includes a recess in which the airflow forms an airflow layer, stopping subsequent airflow from directly contacting the inner peripheral wall of the passage.
