摘要： A method and apparatus is provided for reducing electromagnetic radiation emissions. The method and apparatus of the present invention also reduce or prevent electromagnetic radiation generated by sources outside of a system assembly from interfering with and adversely affecting electrical circuits in the assembly. An electromagnetic compatibility (EMC) solution uses a lossy element, and/or an element comprised of a combination of lossy and conductive material.

摘要： Blower designs for vented enclosures include an impeller having a plurality of blades. The impeller includes a plurality of blades pivotably coupled to an impeller body. The blades pivot to enable operation in one of a closed and an open state. Air flow between blades is substantially restricted when the blades are in the closed state. Air flow between the blades is permitted when the blades are in an open state. In one embodiment, the pivotable couplings are spring loaded to maintain the blades in the closed state when the impeller rotational speed is below a threshold range. The blades pivot to the open state when the rotational speed exceeds the threshold range.

摘要： Blower designs for vented enclosures include an impeller having a plurality of blades. A plurality of one way valves are interleaved between the blades to permit substantial airflow only in one direction. One valve design incorporates flaps coupled to either the blades or the impeller body with spring loaded hinges. Another valve design incorporates a flexible flaps coupled to either the blades or the impeller body. In one embodiment, the one-way valves reside on an insertable hub disposed within an inner periphery of the impeller such that the valves and blades are interleaved. The valves close to restrict air flow when the impeller rotational speed is below a threshold range. The valves open to permit air flow when the rotational speed exceeds the threshold range.
摘要翻译：用于排气罩的鼓风机设计包括具有多个叶片的叶轮。多个单向阀在叶片之间交错，以仅在一个方向上实现大量气流。一个阀设计包括与弹簧加载的铰链联接到叶片或叶轮本体的翼片。另一个阀门设计包括耦合到叶片或叶轮本体的柔性翼片。在一个实施例中，单向阀位于设置在叶轮的内周内的可插入轮毂上，使得阀和叶片交错。当叶轮转速低于阈值范围时，阀门接近以限制气流。当转速超过阈值范围时，阀打开以允许空气流动。

摘要： A blower apparatus includes a blower housing having at least one airflow channel. A flexible sheet having at least one flap is coupled to the blower housing such that the flap overlaps the channel to form a one-way valve. A plurality of flaps may be positioned over a plurality of channels to form a blower apparatus with a plurality of one-way valves. The flexible sheet may include mounting features such as holes to facilitate assembly. For example, in one embodiment, the flexible sheet is pressed onto a plurality of pegs residing on the blower housing such that the holes receive the pegs. In another embodiment, the flexible sheet is pressed onto a plurality of pegs residing on an exhaust cover that is subsequently attached to the blower housing.
摘要翻译：鼓风机装置包括具有至少一个气流通道的鼓风机壳体。具有至少一个翼片的柔性片材联接到鼓风机壳体，使得翼片与通道重叠以形成单向阀。多个翼片可以定位在多个通道上以形成具有多个单向阀的鼓风机装置。柔性片可以包括诸如孔的安装特征以便于组装。例如，在一个实施例中，柔性片被压在驻留在鼓风机壳体上的多个栓钉上，使得孔容纳栓钉。在另一个实施例中，柔性片材被压在驻留在排气盖上的多个钉子上，随后附着在鼓风机壳体上。

摘要： A cooling apparatus comprises a printed circuit board and an air duct positioned adjacent the printed circuit board spanning space and forming an air-guiding channel from at least one system fan to at least one heat sink. The air-guiding channel is bounded on one side by the printed circuit board and on remaining sides by the air duct that compresses against the printed circuit board in a substantially airtight seal.
