Abstract: A method comprises, at a power balancing circuit for three-phase AC power: feeding three power phases to respective loads; measuring power drain on the three power phases by the respective loads; based on measuring, detecting an unbalanced power drain across the three power phases due to a relatively light power drain on one or more lightly loaded power phases and a relatively high power drain on one or more heavily loaded power phases; computing an amount of power to be drained from the one or more lightly loaded power phases and to be fed to the one or more heavily loaded power phases to balance the power drain across the three power phases; and transferring the amount of power from the one or more lightly loaded power phases to the one or more heavily loaded power phases to balance the power drain across the three power phases.

Abstract: A locking mechanism for securing a computing device in an enclosure includes a jaw, a transmission lever, and an arm. The jaw is configured to abut a portion of the enclosure for holding the computing device. The transmission lever includes an arm pivot at one end and an actuating pivot at the opposite end. The arm is configured to rotate open and closed about the arm pivot and be selectively decoupled from the transmission lever. When the arm is coupled to the transmission lever, opening the arm causes the transmission lever to rotate open about the actuating pivot. Rotating open the transmission lever about the actuating pivot releases the jaw from the portion of the enclosure, and allows the computing device to be removed from the enclosure.

Abstract: According to one aspect, an apparatus includes an expansion element, an expandable element, and a frame. The expandable element is configured to have an expanded state and an unexpanded state, wherein the expandable element is arranged to be inserted between a mated pair of printed circuit boards (PCBs) while in the unexpanded state. The expansion element is arranged to cause the expandable element to expand to the expanded state. When the expandable element is in the expanded state, the expandable element causes the pair of PCBs to demate. The frame is arranged to facilitate an insertion of the expandable element between the mated pair of PCBs. In one embodiment, the expandable element is an inflatable element and the expansion element is an inflator element that includes an air supply.

Abstract: A heat sink mounting configuration is provided that is configured to prevent the heat sink from damaging ball grid arrays (BGA) of an application specific integrated circuit (ASIC) mounted on a printed circuit board (PCB) when the line card is subjected to vibrations and shocks. The heat sink mounting configuration may include a set of screws configured to be at least partially disposed within the apertures of the heat sink to secure the heat sink to the PCB. The mounting configuration includes a resilient member and a spacer disposed around the screws proximate to the apertures. The resilient members are configured to bias the heat sink against the ASIC to maintain the heat sink in contact with the ASIC. The spacers are configured to prevent the heat sink from impacting the ASIC with forces large enough to damage the BGA when the line card is subjected to vibrations and shocks.
