Abstract: A warehouse from which shoppers fulfill orders for an online concierge system maintains an online concierge system-specific portion for which the online concierge system specifies placement of items in regions. To place items in the online concierge system-specific portion, the online concierge system accounts for co-occurrences of different items in orders and measures of similarity between different items. From the co-occurrences of items, the online concierge system generates an affinity graph.

Abstract: The automated system provides automated and remote monitoring, control, communication, and management of recreational vehicle parking facilities, providing guests access to electric, water and sewer services via onsite hookup pedestals. Guests use a computerized reservation system to reserve a parking site. The reservation information is provided to the control system for the hookup pedestals. The control system monitors parking site sensors and activates and deactivates the hookup pedestals via smart switches based on the reservation information and sensor data indicating an arrival and departure, respectively. When a reservation window ends or the site is vacated, the system deactivates the hookup pedestals to end access to the utility services while the sensors remain active. When sites are vacated early, the system determines whether there is sufficient time until the next reservation include the sites' open time to the reservation system's inventory of open sites that are available for new reservations.
