  • Publication number: 20130339084
    Abstract: A system and method for offering vetted services of an originator/subject matter expert (O/SME) by a third party source of products and services of multiple O/SMEs may include storing data associated with the O/SME, the data inconclusive of product or service content representative of products or services being offered by the O/SME. Select data associated with the O/SME may be collected. An O/SME vetted data repository storing vetting data representative of vetting results of the O/SME may be queried. In response to receiving vetting data indicative of the O/SME having a vetting score above a passing vetting threshold value, an interactive booking feature may be displayed in relation to the select data associated with the O/SME and activated to enable a user to book services with the O/SME. Otherwise, the interactive booking feature may not be enabled to be displayed and activated.

  • Patent number: 4580279
    Abstract: In an elastic store synchronization system, failures in the slip control circuitry or the elastic store itself are determined by employing a slip maintenance circuit. To this end, parity written into the elastic store is scrambled in a prescribed manner. The slip maintenance circuit generates signals for unscrambling the read parity from the elastic store when no slip is present and to compensate the read parity in the presence of slips so that the appropriate system parity is obtained. Any resulting parity violations indicate a failure of the slip control circuitry or of the elastic store.
