Abstract: A data structure representing the state of courier assignments is described. For each courier assignment, the data structure contains: information identifying a destination location for the courier assignment; information identifying a drop-off protocol specified for the courier assignment, the drop-off protocol specifying a sequence of steps; and, for each of at least some of the steps of the identified drop-off protocol, a representation of compliance evidence collected with respect to the step of the courier assignment. The contents of the data structure are usable to present collected compliance evidence for steps of the drop-off protocol specified for courier assignments among the plurality of courier assignments, either contemporaneously or at later times.

Abstract: A facility (e.g., data center) for more efficient cooling of computing devices is disclosed. In one embodiment, the data center comprises a set of external walls, a ceiling connected to the external walls and having circular exhaust openings, and one or more pods positioned within the external walls and below the ceiling. A set of flexible tubes are used to connect the pod exhaust openings to the ceiling openings. Actuating closures may be used (e.g., at one end of each of the tubes) to control airflow, and air pressure sensors may be placed near or inside one or more of the tubes. A controller may be configured to receive air pressure data from the air pressure sensors and adjust the actuating closures to maintain a desired air pressure level. In some examples, the actuating closure may have a normally closed position when power is not applied.

Abstract: A method for aligning a tree within a resource extraction system includes disposing a riser system on a wellhead of the resource extraction system without utilizing a mechanical alignment system to circumferentially align the riser system with the wellhead. The method also includes disposing a tubing hanger at a landed position within the wellhead. In addition, the method includes disposing an orientation mechanism on the wellhead. The orientation mechanism includes an alignment feature configured to engage a corresponding alignment feature of the tree. Furthermore, the method includes moving the tree toward the wellhead such that the alignment feature of the tree engages the alignment feature of the orientation mechanism to approximately establish a target circumferential orientation of the tree relative to the tubing hanger.
