SDA (Sequenced Data Acquisition) Time Intervals is a hierarchical logging system for describing complex large-scale repeated processes. SDA has been used extensively at Fermilab* for fine tuning during the Tevatron Collider Run II. SDA Time Intervals is a new system born during discussions between CERN and FNAL about routinely recording relevant data for the LHC. Its main advantages are extremly low maintenance and good integration with traditional "flat" dataloggers. The Time Intervals (TI) system records the time of key events during a process and relates these events to the data that the traditional datalogger archives. From the point of view of the application program, any number of datalogging systems can be refactored into human-understandable time intervals.

The "Drag and Drop Display & Builder" system is a component-oriented system that is designed to allow users to create visual representations of data received from data acquisition systems. It is an upgrade of a synoptic display mechanism used in Fermilab since 2002*. Components can be graphically arranged and logically interconnected in the web-startable Project Builder. Projects can be lightweight AJAX and SVG based web pages, or they can be started as Java applications. The system may be used to control equipment if started as a Java application. The new version was initiated as a response to discussions between the LHC Controls Group and Fermilab.
