Abstract: Devices, systems, and methods are provided for enhanced geographical caching of estimated arrival times. A method may include receiving respective user inputs indicative of respective users being in transit to a destination location from within a geographic region; determining, for the first user and the second user, a first estimated time of arrival from a first geographical area to the destination location, the first geographical area including the first location and the second location; identifying a third location of the first device at a third time, wherein the third location is within the first geographical area; determining that a time-to-live (TTL) of the first estimated time of arrival has not expired at the third time; and refraining from recalculating the first estimated time of arrival.

Abstract: Systems, methods, and computer-readable media are disclosed for systems and methods for autonomous device authentication and compartment unlocking. Example methods may include determining, by a user device, an identifier associated with a target Bluetooth Low Energy peripheral device, receiving a beacon from a Bluetooth Low Energy peripheral device, and determining, using the beacon, that the Bluetooth Low Energy peripheral device is the target Bluetooth Low Energy peripheral device. Example methods may include establishing a connection with the target Bluetooth Low Energy peripheral device, and sending a signal to the target Bluetooth Low Energy peripheral device to implement an action, where the signal comprises a resource identifier, and where the target Bluetooth Low Energy peripheral device controls access to a plurality of resources, and uses the resource identifier to identify a resource of the plurality of resources at which to implement the action.

Abstract: A user location in a parking lot or other designated area may be identified based on sensor data, such as from one or more sensors in or around the designated area. Also within the designated area, a transport location of a transport associated with an order of the user may be identified based on image data provided by one or more cameras remote from the transport. The transport can be controlled to move from the identified transport location to the identified user location.

Abstract: A geographical-based fence is established around a store and when an indication is received that a customer is within the geographical-based fence, an estimated time of arrival (ETA) of the customer at the store and/or a time of travel (TOT) of the customer to the store may be determined. Based on the TOT, one or more action(s) may be performed. For example, as the customer comes within a first threshold TOT of the store, a first action may be performed, such as preparing item(s) within the order. As the customer comes within a second threshold TOT of the store, a second action may be performed, such as delivering the one or more items to the customer.

Abstract: A system that performs self-diagnosing of unreliable radio frequency identification (RFID) tags in a first location within an environment includes an RFID printer that prints RFID tags in the first location and RFID antennas located at different distances to the first location. The system obtains, for each RFID tag, a first set of RFID parameters of the RFID tag for each RFID antenna when the RFID tag is in the first location. The system generates, for each RFID tag, a model of RFID tag behavior over different distances to an RFID antenna, based at least in part on the first set of RFID parameters obtained for the RFID tag.

Abstract: A customer may place an order for items to be picked up at a merchant location. Upon receiving an indication that the customer is initiating travel to the merchant location to pick up the items, multiple ETA data points for the customer may be determined while the customer is in transit to the merchant location. Based on the ETA data, it may be determined that the customer is likely to arrive after the merchant location closes, which may prevent the customer from being able to pick up the items from the merchant location. Alternative fulfillment options may be presented to the customer to enable the customer to obtain the items. The alternative fulfillment options may include picking up the items at an alternative merchant location, scheduling a delivery of the items, picking up the items from the merchant location at a subsequent time, or facilitating a cancelation of the order.

Abstract: A system that performs self-calibration for tracking packages includes a frame providing storage locations for storing items, radio frequency identification (RFID) tags disposed in the storage locations, and an RFID antenna(s). The system determines a distance between each RFID tag and the RFID antenna(s) and monitors signal characteristics from each RFID tag. For each RFID tag, the system generates (i) at least one first parameter indicative of an environmental condition(s) at a location of the RFID tag and (ii) at least one second parameter indicative of a response rate behavior of the RFID tag, based on the signal characteristics and the distance between the RFID tag and the RFID antenna(s). The system tracks an RFID tagged item located in one of the storage locations based at least in part on the first and second parameter(s) for each of the RFID tags.
