Abstract: This application relates to apparatus and methods for automatically servicing item data requests in data management systems, such as in retail management systems. The apparatus and methods employ a throttling technique to service data requests from one or more entities. In some examples, a computing device initializes assigns a counter for each entity, and initializes each counter with an initial value. The computing device also occasionally (e.g., periodically) resets each counter to the initial value. The computing device may receive a data request from one of the entities, and determines whether the counter corresponding to the entity identifies a count that is beyond a threshold. If the counter identifies a count beyond the threshold, the computing device adjusts the counter, and processes the data request. If the counter does not identify a count beyond the threshold, the computing device responds to the entity with an error.

Abstract: Described are a system, method, and computer program product for updating and processing payment device transaction tokens. The method includes receiving a first notification based on issuance of a first new payment device, generating a first new token associated with the first new payment device, and linking the first new token to a previous token. The method also includes receiving a second notification based on issuance of a second new payment device, generating a second new token associated with the second new payment device, and linking the second new token to the first new token in a chain. The method further includes determining to deactivate the first new payment device and modifying the chain to remove the first new token. The method further includes receiving a transaction request and processing the transaction request by communicating second new token to an issuer.

Abstract: Described are a system, method, and computer program product for updating and processing payment device transaction tokens. The method includes receiving an update request to update stored transaction information, the update request identifying at least one old payment device and at least one new payment device. The method also includes generating at least one new token associated with the at least one new payment device, and linking the at least one new token to at least one old token. The method further includes receiving a transaction request including the at least one old token, and communicating the at least one new token that is linked to the at least one old token to an issuer for processing of the transaction request.

Abstract: A modular PET gantry is provided herein. A detector module is described, and the detector module includes a plurality of PET detector units. Each detector unit may be bonded to a mounting sleeve. The detector module also includes a mounting frame, wherein each detector unit and mounting sleeve is attached to the mounting frame.
