Abstract: A system for determining a modulus of resilience of a work material during a compaction operation includes a processor configured to determine a work material stiffness based on a force applied to the work material and a displacement of the work material, and determine the modulus of resilience of the work material based on a relationship between the work material stiffness and the modulus of resilience of the work material.

Abstract: The disclosure relates to a system and method for determining a modulus of resilience of a work material during a compaction operation. The system includes a processor configured to determine a work material stiffness based on a force applied to the work material and a displacement of the work material. The processor is further configured to determine the modulus of resilience of the work material based on a relationship between the work material stiffness and the modulus of resilience of the work material.

Abstract: This disclosure describes a system and method to calculate a ground stiffness value. The system includes at least one sensor configured to sense at least one of a vertical acceleration, vertical displacement, and a force of a compactor component and a processor configured to calculate a force at a drum-ground interface in response to the at least one sensor and further configured to calculate a drum displacement in response to the at least one sensor. The processor is further configured to determine ground stiffness using the calculated force at the drum-ground interface and the drum displacement.

Abstract: This process of charging electric and electrically backed up vehicles is done through roof mounted solar panels. With the rising cost and burning fossil fuels, it is designed to extend battery duration while in transit, keeping the electric motors running longer. These solar panels adhere directly to the roofs of any trailer in tow, being very thin, they keep the trailer aerodynamic. This technology is to be used in conjunction with the development of trucks using hybrid technology. Also, this process can be used to power the basic electrical needs of the truck the trailer is connected to, including the air conditioning.

Abstract: This pivoting hook system is designed to give the operator or the spotter on the building control over the swing of material being lifted. It provides a safer distance from under the load, as workers are in potential danger at times when handling tether ropes attached to beams, trusses, etc. as they guide them into place. This device provides a safer alternative to tying a rope to loads for positioning.

Abstract: A method of operating a compactor machine includes determining a value indicative of a compaction state of a region of work material after each of a plurality of compactor passes, and triggering a compaction fault condition if an incipient compaction response satisfies aberrant compaction criteria. A work machine includes an electronic controller configured to trigger a compaction fault condition responsively to sensor input signals indicative that aberrant compaction criteria are satisfied by an incipient compaction response of a work material.

Abstract: Accurately determining the compaction state of a base material during the compaction process is a recognized problem in the construction industry. The present invention recognizes that the compaction state of the base material can be determined by ascertaining the effective roller radius of the compactor. In other words, in the case of powered compactors, the effective roller radius will asymptotically approach the actual roller radius as the base material changes from a soft un-compacted condition to a hard compacted state. Monitoring compaction state via indicative of an effective roller radius can be used alone as a means of determining compaction state in real time, or can be leveraged and combined with other independent means of monitoring the compaction state to a symbiotic affect in more accurately determining compaction state.

Abstract: In most construction processes, some quality assurance compaction test must be performed on a base material before further construction can take place on or relative to the compacted base material. In order to avoid costly downtime associated with waiting for a quality assurance test to be performed, the present invention contemplates generating compaction quality assurance data using on-board generated compaction quality control data. The quality control compaction data is based upon quantifying a sinkage deformation interaction between the compactor and the base material. The interaction might include monitoring an effective roller radius of the compactor, or an amount of energy transferred or consumed when the compactor moves over the base material, or even measuring a rut depth caused by the compactor.

Abstract: The present invention is associated with a system and method of managing a compaction process. The method may include establishing a soil characteristic and establishing a machine performance characteristic in response to the soil characteristic. The machine performance characteristic may include a predictive compaction characteristic associated with a particular machine.

Abstract: A raked bar screen for a storm overflow comprises a grid of parallel spaced-apart bars (1) attached at their ends to a framework (2,3,14). A comb assembly (4,5,6) has teeth (5) which engage in the spaces between the grid bars (1). The comb assembly is longitudinally reciprocable, whereby the comb teeth can sweep longitudinally back and forth between the grid bars. The grid bars are shaped to provide a straight central portion (10) and longitudinal end portions (11, 12) which are angled in relation to the straight portion. In use, sweeping of the comb teeth between the grid bars at the angled end portions drives out entrapped solid matter.

Abstract: An apparatus for the functional assessment of human activity. The invention comprises four major components: the data acquisition unit, a body suit interface unit, a body suit having a plurality of mercury switches and a graphics oriented software package. The body suit is made from a non-conductive material, preferably a thermalactyl material with sensors permanently attached in position corresponding to the movements to be measured. The sensors have no direct electrical contact with the human wearer thus permitting the measurement period to extend to many hours. A portable data acquisition unit which is connected to the sensors enables the system to be used "on the job" to obtain mobility measurements under actual conditions. A graphic analysis means, connected to said data acquisition means, is provided for providing a visual display of the length of time that the human has spent in each of the pre-determined positions and the range of motion measured by the data acquisition unit.
