Abstract: A system for managing a concrete delivery vehicle having a mixing drum 14 and hydraulic drive 16 for rotating the mixing drum, including a rotational sensor 20 configured to sense a rotational speed of the mixing drum, a hydraulic sensor 22 coupled to the hydraulic drive and configured to sense a hydraulic pressure required to turn the mixing drum, a temperature sensor for sensing temperature of the drum, and a communications port 26 configured to communicate a slump calculation to a status system 28 commonly used in the concrete industry, wherein the sensing of the rotational speed of the mixing drum is used to qualify a calculation of current slump based on the hydraulic pressure required to turn the mixing drum. Temperature readings are further used to qualify or evaluate a load. Also, water purge connections facilitate cold weather operation.

Abstract: A reading comprehension system and method that uses language micro-variables is disclosed. The system provide training using these language micro-variables in order to provide reading comprehension training. This training also is highly impactful for the instruction and improvement of reading fluency and vocabulary.
