A system for an index search engine includes a first non-volatile memory having a set of partitions. One partition includes one search array file having one or more search array records. The system also includes a second non-volatile memory having an index structure. The index structure includes a four-memory level configuration. Each memory level has a specified memory length. An entry in each memory level of first three levels contains a value pointing to a starting address of immediate next memory level. An entry in the fourth memory level contains a data value including an indexed field value of one of the search array records.

System and method for an index search engine

Systems, methods, and computer-readable storage media for processing database requests on a database hosted on a stateless, non-persistent computing environment are provided. A server stores database requests to insert update or delete data in a unit of work set identified by a unique code. The database requests are performed on the database upon receiving an instruction to commit the database requests to the database. If an instruction is sent to rollback a unit of work set the database remains unchanged. This allows a client to handle requests in logical groups.

System and method for committing and rolling back database requests

Examples of the disclosure provide systems and methods for managing product returns. A computing system receives, from a user device, a request for returning a product, compares device identifier data associated with the user device with registered data associated with one or more customer accounts to identify a first customer account associated with the user device, analyzes transaction data associated with the first customer account to determine whether the product is associated with the first customer account, generates an instruction to position the product in a predetermined area, and determines whether the product is positioned in the predetermined area to facilitate a return of the product. Aspects of the disclosure may improve user experience, user efficiency, and/or user interaction performance by processing a product return in an effective and efficient manner.

Managing product returns associated with a user device

A landing pad receptacle receives and stores a package delivered by an unmanned vehicle, comprising: a housing; a storage compartment in the housing; and a validation device that detects a presence of a package delivered by a unmanned vehicle in the storage compartment and authenticates a package for return by a unmanned vehicle.

Landing pad receptacle for package delivery and receipt

A system includes one or more processing modules and one or more non-transitory storage modules storing computing instructions configured to run on the one or more processing modules and perform acts of: receiving, from a user computer, a destructive read request including header information indicating that a record stored in a persistent database is to be deleted after the record is successfully read from the persistent database; in response to receiving the destructive read request, retrieving the record, which was identified by the destructive read request, from the persistent database; after retrieving the record, receiving a success signal that confirms that the record was successfully read from the persistent database; and in response to receiving the success signal, automatically deleting the record, which was identified by the destructive read request, from the persistent database without receiving another instruction to delete the record. Other embodiments are disclosed herein.

Database protocols and retrieval techniques

A system and method for producing a new globally-unique identifier (GUID) format that may be used, for instance, to uniquely identify a number of different items in a distributed computer system, such as transactions in an e-commerce system, sessions in a cloud-based computing system, and identifiers for unique customers in an ecommerce system, among others. The unique ID may have one of a number of different formats that may be generated upon receiving a request for an ID. For instance, the GUID may be generated in a plain hex format, a GUID format, ESS, and B64B (Base64Binaty) format. The new format may be generated based on information relating to a site ID, an absolute time, and a sequential counter, that ensures that no two GUIDs are the same. Further, the system may be capable of issuing multiple GUIDs within a single command, such as may be required to generate an array of GUIDs.

System and method for generating globally-unique identifiers

A technique for detecting spills is disclosed. A number of electrodes within a portion of a surface are connected to a resistance meter. The resistance meter detects a spill by measuring a change in resistance between two or more electrodes when a fluid is spilled over the two or more of the electrodes. The location of the spill can also be determined based on a known location for each of the electrodes. The size of the spill can further be determined based on a number of electrodes which measured a change in resistance due to the spilled fluid.

Systems, devices, and methods for detecting spills

A technique for detecting spills is described. A number of audio sensors detect a sound potentially associated with an object spilling on a surface and the audio data from the sensors is analyzed in order to generate an acoustical analysis of the sound. The analysis of the sound detected by the audio sensors is compared against a database of known sounds corresponding to a number of types of spill incidents. Based on a match detected between the analysis of the sound and a type of spill incident in the database of known sounds, the identity of the object spilled can be determined. The location of the spilled object can also be calculated by triangulating the sensor data from the audio sensors.

Systems, devices, and methods for detecting spills using audio sensors

A system for providing a cloud-based data session can be implemented to allow access to session data for client applications across multiple platforms and environments. In embodiments, a system for provisioning data sessions includes a session provision service, cache provision service, unique identifier provision service, and a data store. The unique identifier provision service is programmed to create a unique identifier that is guaranteed to be globally unique across multiple systems so that each unique identifier is unique assigned to only one data session.

Cloud-based data session provisioning, data storage, and data retrieval system and method

A system for delivering store items to a selected destination comprises a store computer that receives selected store item data including a delivery request; a delivery request database that stores the delivery request; and a delivery request application processor that provides a rule that includes criteria for selecting at least one delivery driver and generates a result that identifies a delivery driver of the at least one delivery driver satisfying the criteria of the generated rule.

System and method for facilitating bids by delivery drivers on customer store item deliveries

An automated system for automatically mixing and verifying paint is described. The system may include a kiosk configured to automatically add a paint of a second color to a paint container holding a first color of paint so as to produce a requested third color of paint. The system may further verify that the mixed paint color is the requested paint color using a laser to perform verification.
