  • Publication number: 20250230002
    Abstract: Disclosed herein are system, method, and computer program product embodiments for real-time concrete production performance monitoring with enhanced process control and reporting. For example, a hopper coupled to a truck may be detected to be under a loading point of a concrete plant based on one or more signals provided by one or more sensors. An identifier associated with the truck is obtained. A determination is made that the identifier is associated with a ticket that indicates that the truck is scheduled to be loaded from the truck loading point of a concrete plant. A determination is made that the truck is ready to be loaded based on (i) detecting that the hopper is under the truck loading point (ii) the truck drum is rotating at the proper speed and direction and (iii) determining that the identifier is associated with the ticket.

  • Patent number: 10359413
    Abstract: A method and system for calibrating moisture sensors in a concrete production plant are disclosed. The moisture sensor is in communication with a computer database through a transceiver. The moisture sensor records numerous readings of moisture for aggregate used in concrete production, which are stored in the database. Separately, a manual sample of aggregate taken from the production line is determined to have a moisture content, which is the baseline for calibrating the sensor. This record is also entered into the database. The moisture sensor reading and the manual sample record are compared for multiple iterative readings to determine whether a sensor requires further calibration.

  • Publication number: 20080312828
    Abstract: A method for providing geographic directions having the steps of: providing a server system capable of electronic communication with a communication device; the server system, receiving a call from a communication device, the communication device being under the control of a user, receiving human speech in the form of electronic information from the communication device, recording the human speech, converting the human speech into electronic text and attempting to match the text to a destination address on a map server, upon failing to match the text to a destination address on the map server, transmitting the recorded speech to a human operator who listens to it and ascertains a destination address; upon receiving the ascertained destination address, the server system rendering a map from the location of the communication device to the destination address, and transmitting the map to the communication device.
