Abstract: A system for determining the rotational direction of a ready mix concrete truck drum can be used to accurately determine the time interval between when a batch of concrete is loaded into a ready mix truck and when it is discharged. This time interval is critical to the overall quality of the concrete. The present invention comprises a camera, a computing platform, and software that runs on the computing platform that can interpret the visual data captured by the camera and determine the rotational direction of the ready mix drum. This rotational direction data can then be used to determine the time interval from when the concrete is loaded on the truck and when the concrete is discharged. This time interval directly relates to the quality of the concrete.

Abstract: A system for proactive maintenance of a telecommunications network. A database is created containing characteristics of a plurality of valid logs. These valid logs represent alarms within a network which report status and abnormalities in the network and which have been specifically selected by a network domain expert or administrator from a larger group of logs. The characteristics correspond to a pattern of network fault parameters. The network is monitored for occurrences of a valid log. When a valid log is encountered, future occurrence of a fault is predicted based on an analysis of the valid log and the characteristics found in the database. Corrective measures are taken to prevent the fault from occurring.
