    • A control logic detects voltage regulator failure in a power supply. The control logic comprises first and second lines configured for respective connection to a controller node and a phase node of a voltage regulator, a delay element coupled to the first line configured to delay signals at the controller node into alignment with signals at the phase node, and a level detector coupled to the second line configured to convert the signals at the phase node into at least two digital representations indicative of respective signal thresholds. A logic compares timing of the delayed signals with the digital representations and detects occurrence of a voltage regulator fault based on the timing comparison.

    • Unwanted RF emissions from an imperfect enclosure surrounding an electronic apparatus are reduced by first investigating the RF field strengths inside the enclosure while the apparatus is in operation, and identifying locations where the field strengths are significantly higher than elsewhere. The field strengths at these identified locations are then lowered significantly by placing lossy materials thereat to absorb and thus dissipate RF energy. If the lossy materials are placed in the near field of the actual circuitry that generates the RF then some of that RF is dissipated according to the degree of loading, but without associated reflected energy, and without the need for the lossy material to be a free field absorber that matches the characteristic impedance of the interior of the enclosure. A hybrid arrangement also exists where the lossy material is neither a free field absorber nor located in the near field of the generator, so long as it is located in the near field of a reflector. Thus, a significant portion of the RF that would otherwise leak out is absorbed before it gets the chance, thus reducing the absolute amount of energy that does leak out.
    • 通过首先在设备运行时首先研究外壳内的射频场强度,以及识别场强显着高于其他地方的位置,来减少来自电子设备周围的不完美外壳的不期望的RF发射。 然后通过在其上放置有损耗材料来吸收并消散RF能量,从而显着降低了这些识别位置处的场强。 如果有损耗材料被放置在产生RF的实际电路的近场中,那么RF中的一些根据负载的程度而消失,但没有相关的反射能量,并且不需要有损耗材料是自由的 场吸收器匹配外壳内部的特性阻抗。 还存在混合布置,其中有损材料既不是自由场吸收体也不位于发生器的近场中,只要其位于反射器的近场中。 因此,否则泄漏的RF的很大一部分在其获得机会之前被吸收,从而减少漏出的能量的绝对量。
