Abstract: An online concierge system compensates pickers who fulfill orders including one or more items based in part on weights of the items included in an order. Because the online concierge system does not physically possess the items that are obtained, the online concierge system cannot directly weigh the items and weights specified for items in a catalog from a retailer may be inaccurate. To more accurately determine weights of items, the online concierge system trains a weight prediction model to estimate an item's weight from attributes of the item and uses the output of the weight prediction model to determine compensation to a picker. The weight prediction model may output a predicted weight of an item or a classification of the item as heavy or light. Where discrepancies are found between a predicted weight and the catalog weight of an item, additional information about the item is obtained.

Abstract: Embodiments relate to order specific expansion of an area that encompasses pickers available for accepting an order placed with an online system. The online system accesses a computer model trained to predict an attractiveness metric for the order and applies the computer model to predict a value of the attractiveness metric for a first order. The online system classifies the first order into a first set or a second set, based on the value of the attractiveness metric and a threshold. Based on the classification, the online system expands over time a size of an area that encompasses a set of pickers available for accepting the first order. The online system causes a device of each picker in the set of available pickers located within the area of the expanded size to display an availability of the first order for acceptance by each picker in the set of available pickers.

Abstract: This disclosure relates to techniques for performing encryption and decryption operations and that provide fully non-custodial data management, i.e., where end-users have control over their data—rather than a third party. Specifically, the techniques disclosed herein are configured to allow end-users to have the ability to recover and/or maintain access to data stored on third-party systems—even if one or more third-party entities storing the data are no longer in compliance with a predetermined set of operational criteria. In other implementations, novel split private key generation techniques are disclosed, wherein a newly-generated private key may be split into at least three shards, e.g., an authentication service provider shard, a shard for another entity, and a “recovery” shard. In still other implementations, an iFrame may decrypt separate shards of a private key using a delegated key management system (DKMS) and then use the reconstructed private key to sign a digital transaction.

Abstract: A mechanism for building decentralized computer applications that execute on a distributed computing system. The present technology works within a web browser, client application, or other software and provides access to decentralized computer applications through the browser. The present technology is non-custodial, wherein a public-private key pair, which represents user identity, is created on a client machine and then directly encrypted by a third-party platform without relying on one centralized computing system.

Abstract: The present disclosure provides a battery pack, including: battery modules, wherein two or more of the battery modules are arranged side by side in a first direction; and connecting assemblies, wherein each connecting assembly is connected between adjacent two battery modules, and the connecting assembly includes an elastic connecting member being able to elastically deform in the first direction such that the adjacent two battery modules are elastically connected by the connecting assembly. The elastic connecting member can provide a buffer between the adjacent two battery modules. In the case that one of the adjacent two battery modules suffers a force, the elastic connecting member can absorb a force from this battery module, to prevent the adjacent two battery modules from interacting with each other when suffering the force, and avoid a safety accident caused by the interaction between the two battery modules connected to each other.

The method comprises the following steps: (1) preparing a quantum rod solution; (2) preparing a polymer solution, and adding the quantum rod solution obtained in step (1) into the polymer solution so as to form an electrospinning precursor solution with a volume concentration of the quantum rods of 5%-80%; and (3) adding the electrospinning precursor solution into an electrospinning device, regulating the voltage of a generator and the receiving distance, and then performing electrospinning to prepare the quantum rod/polymer fiber membrane. By adjusting the concentration of the quantum rod solution and parameters in the electrospinning process, the method realizes directional arrangements of the quantum rods in the electrospinning process, thereby obtaining the quantum rod/polymer fiber membrane with high degree of polarization performance.
