摘要： Apparatuses and methods are provided for locking an air-moving assembly within a chassis when in operational state. The apparatus includes a locking louver assembly having a louver(s) and locking mechanism. The louver(s) is disposed at an air inlet or outlet of the air-moving assembly, and pivots between operational and quiesced orientations, dependent on presence or absence, respectively, of airflow through the air-moving assembly. The locking mechanism includes a keying element(s) affixed to the louver(s) to pivot therewith, which includes an elongated key(s) oriented in a first direction when the louver(s) is in operational orientation, and a second direction when in quiesced orientation. A key-receiving element(s) is associated with the chassis and includes a key opening(s) which receives and accommodates movement of the elongated key(s) between the first and second directions, and prevents removal of the air-moving assembly from the chassis with the key(s) oriented in the first direction.

摘要： Power distribution modules in distributed antenna systems include fan monitoring circuits for indicating an alarm condition to head-end equipment. The alarm condition can be used by system operator/owners that a fan is drawing excessive power, thereby detracting from system performance, or indicating that the fan may fail. The alarm condition signal can be returned to the head-end equipment via an uplink communication path between a remote unit powered by the module and the head-end equipment.

摘要： An apparatus including a base plate, and a plurality of diaphragms is provided for preventing refluence of air in an electronic device. Each diaphragm includes a hollow main body, and a plurality of movable petaline portions extending out from an end of the main body. Difference in air pressure may cause the petaline portions of each of the diaphragms to press together to form a closed position to block passage of air through the main bodies of the diaphragms from one direction or move away from each other to form an open position to allow passage of air through the main bodies from an opposite direction.

摘要： An inlet recirculation apparatus for an air moving device includes a housing defined by a wall extending from a base. The base includes an aperture therethrough receptive to alignment with an inlet of the air moving device. A plurality of flaps each pivotally extends radially outwardly from a center pivot to another corresponding pivot disposed around a perimeter of the wall. The center pivot is coaxial with a center of the aperture. Each flap moves to an open position due to air pressure from the air moving device causing air to flow into the inlet wherein each flap pivotally rotates about the center pivot and corresponding pivot at the wall, and moves to a closed position when air pressure from the air moving device ceases wherein a space between contiguous flaps is eliminated when each flap pivotally rotates to the closed position about the center pivot and corresponding pivot at the wall to prevent reverse airflow through the air moving device.

摘要： An embedded computer chassis may include a midplane having a first side and second side substantially opposite each other, where the midplane is suitably adapted to receive at least one computer card in each of the first side and the second side. Embedded computer chassis may further include a cooling region suitably adapted to cool the at least one computer card, where at least a portion of the cooling region is suitably adapted to receive a first fan tray and a second fan tray, where the first fan tray is suitably adapted to couple to the first side of the midplane, and where the second fan tray is suitably adapted to couple to the second side of the midplane. The first fan tray and the second fan tray are substantially redundant for removing the heat generated by the at least one computer card.

摘要： A method for preemptively detecting fan failure is provided. The method may include measuring at least one parameter associated with the fan, such as sound, wobble, smoke, or the like, and predicting a time at which failure of the system is anticipated based on said measured parameter. Thereafter an indication of the predicted time at which failure of the system is anticipated is provided. Maintenance of the system to repair or replace the fans may then be scheduled as part of a regularly scheduled maintenance call, reducing the cost associated with the fan failure.
