Abstract: An orthogonal coupling mechanism includes a threaded rod, a pair of travelers engaging the threaded rod, and an actuator. The actuator is disposed on the threaded rod, such that the actuator translates a first axial force along the axis of the threaded rod into a rotational movement of the threaded rod about its axis. The rotational movement created by the actuator causes the pair of travelers to travel along the axis of the threaded rod, moving a sliding board into engagement with a first connector in a direction orthogonal to a direction of the first axial force.

Abstract: An information technology (IT) rack that includes IT appliances, housed by the IT rack, and a set of backplanes. Each backplane includes appliance-interfacing connectors. Insertion of the IT appliances into the IT rack causes mating of backplane-interfacing connectors of the IT appliances with the appliance-interfacing connectors. The IT rack further includes a centrally located interface to which the appliance-interfacing connectors are wired. The centrally located interface determines a connectivity of the IT appliances.

Abstract: A system for thermal management of a heat sink via active surfaces. The heat sink includes a cavity within the heat sink, and a nozzle. The nozzle provides a pathway from the cavity to a surface of the heat sink. The heat sink also includes a membrane attached to the cavity and an actuator of the membrane, causing the membrane to oscillate. The oscillation of the membrane causes inflow and outflow of a medium through the nozzle.

Abstract: A server system includes a plurality of stacked modular computing structures. Each modular computing structure includes a circuit board comprising a computing resource, an air-fluid heat exchange structure comprising a first set of pipe segments, and a cold plate structure attached to a second set of pipe segments of the modular computing structure. The first set of pipe segments of each modular computing structure interfaces with the first set of pipe segments of at least one adjacent modular computing structure to form a corresponding section of a first fluid circulation loop. The second set of pipe segments of each modular computing structure interfaces with the second set of pipe segments of at least one adjacent modular computing structure to form a corresponding section of a second fluid circulation loop.

Abstract: A contactless connector requires no physical contact. A terminated transmitting transmission line on a first board is parallel to a dual-terminated receiving transmission line on a second board. The boards are placed face-to-face with a small air gap in-between. A driver drives a driven pulse onto a first end of the transmitting transmission line. The driven pulse capacitively induces a positive induced pulse on the first end of the receiving transmission line. As the driven pulse travels from the first end to the second end of the transmitting transmission line, energy is transferred to the induced pulse, which travels down the receiving transmission line. Inductive coupling becomes stronger than capacitive as the length increases, so that at the second end, the induced pulse is negative and then swings positive. A Schmitt trigger receiver on the second end of the receiving transmission line detects the signal.

The nodes in the torus are interconnected using links. A host in the network is connected to a subset of nodes where nodes in the subset are associated with different tori. The host transmits the packets to the parallel tori interconnect by selecting a node the subset of nodes. The packets are transmitted using links between from the node to the plurality of nodes in the torus, but not between the plurality of tori.

Abstract: A server system includes an array of server cells. Some or all of the server cells include a set of at least three side panels forming an enclosure and a compute component comprising a processor core. At least one side panel of each server cell is removably mechanically coupled and removably electrically coupled to a facing side panel of an adjacent server cell. The enclosure may form a triangular prism enclosure, a cuboid enclosure, a hexagonal prism enclosure, etc. The enclosure can be formed from a rigid flex printed circuit board (PCB) assembly, whereby the side panels are implemented as rigid PCB sections that are interconnected via flexible PCB sections, with the flexible PCB sections forming corners between the rigid PCB sections when the rigid-flex PCB assembly is folded into the enclosure shape. The compute component and other circuit components are disposed at the interior surfaces of the rigid PCB sections.

Abstract: An electronic assembly includes a circuit board that serves as both a mechanical attachment point and signal conduit for electronic components. The circuit board includes at least two modular card connector assemblies disposed on opposing surfaces of a mounting region of the circuit board. Pin sets of the modular card connector assemblies are connected together via corresponding through holes extending between the opposing surfaces in the mounting region. Further, pins of one or both the modular card connector assemblies may be connected to other electronic components disposed at the circuit board via lateral traces. One or both of the modular card connector assemblies can comprise a modular card socket to removably couple with a modular card. Alternatively, one or both of the modular card connector assemblies comprises a pin interface assembly that is integral to or otherwise fixedly attached to the modular card.

Abstract: A lever mechanism facilitates coupling of a sliding board and a connector. A sliding board is partially enclosed by a sliding board enclosure, such that the sliding board is slidable relative to the enclosure. A pair of pivot levers is disposed between the sliding board and the enclosure. Each pivot lever is connected at a proximal end to the enclosure and at a pivot point to the sliding board. A distal end of the pivot lever is removably engageable with a second circuit board. The lever mechanism translates a pushing force on the enclosure to a pulling force on the sliding board, aligning and eventually coupling the sliding board with the connector.

Abstract: A cluster computer server is configured after a system reset or other configuration event. Each node of a fabric of the cluster compute server is employed, for purposes of configuration, as a cell in a cellular automaton, thereby obviating the need for a special configuration network to communicate configuration information from a central management unit. Instead, the nodes communicate configuration information using the same fabric interconnect that is used to communicate messages during normal execution of software services at the nodes.

Abstract: An electronics chassis has many removable boards on sleds that are interconnected by a honeycomb interconnect structure. Interconnect boards in Y-planes and Z-planes are orthogonal to each other and form cells. Cooling air flows through the cells in an X direction, parallel to surfaces of the interconnect boards. The removable boards have connectors that mate with an edge of Z-divider interconnect boards. Fans blow air through the cells in the honeycomb structure unimpeded since no boards are perpendicular to the airflow. Notches in the rear of the Z-divider boards provide airflow equalization allowing closer spacing of fans to the honeycomb structure. A sled carrier honeycomb structure is placed in front of the honeycomb interconnect structure to guide sleds into position. Sled carrier dividers are offset from the Z-divider boards to allow removable boards to align with Z-divider boards in the Z-planes, parallel to airflow.

Abstract: Processing nodes in a 3D torus network topology are connected together via an interconnect that introduces at least one irregularity into the link connections between processing nodes of each ring of the network. Each processing node detects whether there is an irregularity in its links with adjacent processing nodes in a ring. As the sockets or other processing node interfaces of the interconnect are wired to introduce this irregularity and as the positions of the processing nodes within a given ring are relative to this irregularity, the physical location of the processing nodes can be determined based on correlations between physical locations of the sockets relative to the irregularity and the positions of the processing nodes relative to the irregularity. Thus, the relative position of a processing node in the ring can be used to identify the socket with which the processing node is coupled, thereby facilitating network management operations.

Abstract: Systems and methods for actively reducing or eliminating conducted noise from power provided to DC circuits include a current sensor, a boost converter, a buck converter, and energy supply capacitors. The current sensor senses the input current provided by the power source. The boost converter increases the voltage level above that provided by the power source while maintaining current at or near the level sensed by the current sensor, and while also maintaining a charge on the energy supply capacitors. The buck converter is powered by the output from the boost converter and provides an output voltage to a load. The operation of the boost converter and the buck converter may be controlled to maintain a continuous and low ripple current from the power source and to maintain a continuous and low ripple voltage to the load.
