    摘要： An incandescent electric lamp having an envelope and means for reflecting infrared energy back to the filament to increase its operating temperature while transmitting visible energy. The envelope is shaped to reflect the infrared energy back to the filament and the filament is purposely misaligned with respect to the optical center of the envelope so that the infrared energy impinges on the filament after two reflections from the envelope wall.

    摘要： An apparatus to actively monitor a network having a plurality of twisted-pair communication links. The apparatus includes a plurality of amplifiers corresponding, respectively, to the plurality of twisted-pair communication links, each amplifier having a sufficiently high input impedance and common-mode voltage tolerance to non-intrusively copy a data signal transmitted through a corresponding twisted-pair communication link and amplify the copied data signal. The apparatus further includes a plurality of isolation transformers corresponding, respectively, to the plurality of amplifiers, each isolation transformer receiving the amplified, copied data signal from the corresponding amplifier, and outputting a transformed data signal, and a connector receiving the transformed data signals from the plurality of isolation transformers in a pin order corresponding to the plurality of twisted-pair communication links. A protocol analyzer is also provided to receive the transformed data signals via the connector for decoding and monitoring purposes.
