    摘要: An approach is provided in which a cooling manager detects a failed fan included in an electronic enclosure. The electronic enclosure includes multiple fans that each cool different component areas in the electronic enclosure. The cooling manager selects an airflow compensator that corresponds to a functioning fan included in the electronic enclosure, which includes a fixed perforated member and a movable perforated member. In turn, the cooling manager adjusts the selected airflow compensator to redirect a portion of airflow generated by the functioning fan to the component area corresponding to the failed fan.

    摘要: An active clamp circuit for digital circuits includes a first MOSFET serially connected between an upper power supply voltage and an input terminal to be clamped, and a second MOSFET serially connected between a lower voltage power supply and the input terminal. The voltages at the gates of the first and second MOSFETs are held at constant first and second reference voltages by a reference circuit and the first reference voltage at the gate of the first MOSFET is less than the second reference voltage at the gate of the second MOSFET. The first and second reference voltages can be changed by connecting the reference circuit to power supply voltages other than the power supply voltages to which the first and second MOSFETs are connected. The reference voltages can also be varied by adding stages of transistors which act as resistors in parallel to the reference circuit. When the first reference voltage is to be varied, it is recommended that the transistors of opposite type be biased independently. The clamping action can be switched on or off, and when the clamping action is switched off, the voltage on the first and second MOSFETs is kept from floating by connecting the gates to turn-off transistors. The device is particularly suited for use with silicon-on-insulator.

    摘要: A high frequency connector utilizes flex strip signal/reference conductor pairs extending in channels formed in a dielectric connector body between terminations at connector ends. The flex strips are formed as signal and reference conductor traces separated by a flexible dielectric wherein the impedance can be influenced by the width of the signal and reference traces and the thickness and selected material of the dielectric separating the adjoining conductor traces. Design of the flex strip assemblies is used to vary the capacitance which enables the connector impedance to match the impedance of the circuits and/or cables connected to the connector and mitigate any discontinuities among the sequence of circuit paths. The close proximity of signal and reference traces within the pair and the separation of signal lines in the connector body reduces cross talk by minimizing mutual inductance between signal lines.
