Abstract: System and method for automatically calling back a customer via a predictive model determines a plurality of call-back metrics for a plurality of advisor records. The predictive model is applied to call-back data to identify customers that are likely to require a series of call-backs, and automatically generates a preferred call-back to such customers to reduce this risk. The automated call-back may follow termination of an identified customer's inbound call, or at some time after completion of a previous call interaction of the identified customer with an advisor. In the predictive model, a first compilation of call-back metrics record is representative of an overall likelihood of call-backs associated with each advisor record, and a second compilation of the plurality of call-back metrics is representative of a likelihood of call-backs for each of the plurality of products of the enterprise associated with the advisor record.

The latch handle module is integrated in the lid and located at another side edge of the lid, opposite the hinge.

Abstract: An access object authentication method includes a trusted component that is in a computing device and that completes an access object authentication process. When a client requests to access a target object, the trusted component receives an object identifier (ID) and an authentication ID of the target object from the client to perform, based on the authentication ID, tenant authentication on a tenant to which the client belongs. When the authentication on the tenant to which the client belongs succeeds, the trusted component accesses a storage device based on the object ID of the target object.

Abstract: A non-volatile memory apparatus performs a memory operation using one or more parameters that are set or adjusted based on an amount (e.g., percentage or ratio) of non-volatile memory cells that have not experienced programming since a last erase process. The amount of non-volatile memory cells that have not experienced programming since the last erase process is determined as a function of current measured in the non-volatile memory apparatus. To take into account changes to the non-volatile memory over time, the current value used to determine the amount of non-volatile memory cells that have not experienced programming since the last erase process is offset based on a number of program/erase cycles experienced.
