Abstract: Presented are embodiments of a system and method that tracks user actions associated with a displayed advertisement, absent of cookie technology. The system may generate an ETag in response to a user action, such as an ad click, and transmit the ad media to the user. The system may then determine whether other actions performed by the user resulted from the advertisement.

Abstract: An electronic storage and computing system wherein raw point of sale data is transformed into a predefined standardized configuration from which object values representing select business activities are derived and compared to predefined reference values for the selected activities. The system includes an electronic storage device for storing raw point of sale data, a data interpreter for transforming the raw data into a predefined standardized configuration, and a processor for deriving object values from the transformed data according to a set of mathematical/relational functions, the object values being representative of selected business activities, and comparing the object values to predefined reference values for the selected business activities. The data interpreter operates according to a set of control programs to selectively transfer point of sale data from a set of raw databases into a set of standard databases having a predefined standardized configuration.

Abstract: A disk control system offloads to the disk controller much of the overhead associated with disk operations and makes the CPU available for other work. A command block that fully specifies a user request for a disk operation is forwarded to the disk memory unit. The command block contains a unique identifier for tracking of user requests. User requests are executed by the disk memory unit in an order that is most efficient for the disk drive system. The status of a user request is communicated to the CPU via an interrupt and a status block containing the unique identifier. The status block indicates status conditions such as command read, completion and DMA channel request. The disk driver contains a work queue for user requests that have not been forwarded to the disk memory unit and a pending queue for user requests that are awaiting completion by the disk memory unit. By manipulation of the work queues and pending queues, the disk controller can be automatically reinitialized when an error occurs.
