Abstract: In some implementations, a method performed by data processing apparatuses includes receiving, from a requestor device, an item location request for an item. Map information is received for a mapped space in which the item is located. Item location coordinates are received corresponding to locations within the mapped space at which the item has been previously selected or scanned. The item location coordinates are mapped with respect to the mapped space, and a plurality of clusters are determined for the item location coordinates. For each cluster, a representative location of the cluster is determined. One of the clusters is selected, based at least in part on its representative location, and an estimated location of the item is provided to the requestor device, based at least in part on the representative location of the selected cluster.

Abstract: Disclosed herein are embodiments of an oxygen quick connect device and method of using the same, the quick connect device includes a female coupling that has a first end and second end and a bore extending longitudinally through the first and second ends and further includes a biased plunger disposed within the bore of the female coupling and configured to reciprocate within, a seal member disposed on the plunger and configured to seal at a location on the bore of the female coupling, a catch device disposed at a second end of the female coupling body, and mechanism for connecting the female coupling to an oxygen supply source. The device also includes a male insert that has a first end and a second end and a first bore extending longitudinally through the first and second ends and groove for engaging with the catch device.
