摘要： The average EMR emissions of an electronic device may be reduced by implementing an electrically-active modulated termination. For example, the impedance may be continuously varied at one or more termination locations between two metal substructures to cause a like variation in the amplitude of each component of the EMR. According to one approach, cyclically varying the electrical impedance with a period of less than the time interval over which the EMR is measured will result in a reduction in the average measured EMR.
摘要翻译：电子设备的平均EMR发射可以通过实现电活动调制终端来减少。例如，阻抗可以在两个金属子结构之间的一个或多个终止位置处连续变化，以引起EMR的每个部件的振幅的相似变化。根据一种方法，以小于测量EMR的时间间隔的周期周期性地改变电阻抗将导致平均测量的EMR的减小。

摘要： A multi-port LAN switch is provided that enables attached network devices to both communicate directly and to insert into a token-ring network through an attached concentrator. Each port of the multi-port LAN switch has a first transformer, a second transformer, and a switching system. The first transformer has a first winding connected to a first connection of the port. The second transformer has a first winding connected to a second connection of the port. The switching system switches to a port mode or an adapter mode as a function of a mode signal transmitted to the port. In the adapter mode, the switching system connects a second winding of the first transformer to a transmitter circuit in the port, and its connects a second winding of the second transformer to a receiver circuit in the port. In the port mode, the switching system connects the second winding of the first transformer to the receiver circuit in the port, and it connects the second winding of the second transformer to the transmitter circuit in the port. Each port of the multi-port LAN switch further includes a DC voltage source that is switchably connected to the first connection of the port through a first switch. Each port further includes a second switch that connects the second connection of the port to a DC return-path in a first position, and connects the second connection to the first connection when in a second position.

摘要： A system and method for mitigating EMI in an electronic device rely on a set of foam dummy plugs specially configured for insertion into socket connectors according to connector type. The foam plugs have no electrical terminals or wiring, but are made from a foam composite material that attenuates electromagnetic radiation by absorption. The foam composite material includes a foam matrix and electrically conductive particles impregnated within the foam matrix. A handle may be unitarily formed with the foam plug. The handle may include a stamped through-hole, forming a ring, to facilitate insertion and removal of the dummy plugs by hand.

摘要： A slot-type processor and one or more cache modules are incorporated into a vertically oriented, multiple chip module (CM) that is mounted to a printed circuit board. The MCM operates at ultra high frequencies and very high temperatures. Each component of the MCM has a heatsink, a thermal plate, and a series of mounting clips and screws which combine to dissipate heat. The heatsinks and thermal plates generate most of the electromagnetic interference (EMI) since they are not attached or grounded to the board. A series of alignment posts extend from the board and are used to individually and slidably mount each of the components to the board. Each thermal plate is grounded to the posts with grounding clips. The clips maintain contact with the thermal plate through wiping elements. Additional pressure is applied to the wiping elements through a post retaining bracket. The components are fully seated and retained in position with retaining cams.
