    Abstract: A storage unit of a time-series data accumulation device of an embodiment stores statistical value data. A determination unit determines an interval function on the basis of data capacity, and a total amount of time elapsed from the beginning of measurement of a time-series data. A first calculation unit calculates an interval indicating an amount of time required to measure all the time-series data items constituting desired statistical value data on the basis of the determined interval function. A second calculation unit acquires all the time-series data items on the basis of the calculated interval, and thereafter calculates the statistical value on the basis of all the acquired time-series data items.

  • Patent number: 9605994
    Abstract: Real time monitoring and comparison of bucket payload and truck payload during a loading process allows calculation of material lost in transfer between the loader and the truck. The lost or spilled material represents increased costs due to additional trips of the loader to fully load trucks and also in non-value added worksite cleanup time. The payload monitoring system can not only evaluate the mass of material lost over a period of time but can also calculate the value of that lost material using real time commodity pricing. The period of time can range from a single bucket dump to a workshift or longer. Payload masses and/or calculated values may be communicated directly between vehicles or may be communicated in conjunction with a central station.

    Abstract: A system and method for establishing a weight related risk profile using RFID technology is provided. While the cargo container is in transit, a RFID reader inside a cargo container polls the contents of the container by reading RFID data from each RFID tagged item and calculate the payload weight. When the truck transporting the cargo container passes a weigh station, or a high-speed scale embedded in the road, a payload weight is measured by a scale. A risk factor is assessed by comparing the estimated weight by the RFID reader with the measured weight by the scale. According to one aspect of the invention, the RFID based polling system has the ability to map the weight and location for each tagged item and estimate a container weight distribution. The estimated weight distribution is compared with the weight distribution measured by the scale to determine potential anomalies.

  • Patent number: 8571829
    Abstract: Objects in a cargo shipping container are detected by measuring vibration resonant frequency peaks of the container. The mass of an object on the floor of the container effects the vibration resonance of the container, enabling the object to be detected. A vibration source and a plurality of accelerometers are either attached to the steel structure of the container, or are disposed on a supporting structure, such as a cargo crane or lift, so that they contact the container. The vibration source causes the container to vibrate, and the accelerometers detect the vibration resonance of the container. A mismatch between a cargo manifest and an observed cargo, or detection of an object having relatively high mass, e.g., due to lead shielding, can justify a manual inspection. The process uses synchronous processing to achieve the sensitivity needed, is unobtrusive, and does not slow the flow of cargo through a facility.

  • Patent number: 8265836
    Abstract: A load weight measuring device for a multi-stage mast forklift truck has a mast assembly, an oil passage, a flow regulator valve, a pressure sensor, a detecting device, a memory, a selector, and a calculator. The mast assembly has a lift bracket for receiving a load weight, a multi-stage mast unit having masts, and a multi-stage lift cylinder unit having lift cylinders each having an oil chamber for raising the lift bracket along the masts. Hydraulic oil flows in the oil passage. The pressure sensor detects a pressure of hydraulic oil and outputs a pressure signal. The detecting device detects a state which stage of the lift cylinder raises the lift bracket and outputs a detection signal. The memory stores predetermined parameters from which the selector selects the parameter based on the detection signal. The calculator calculates the load weight based on the selected parameter and the pressure signal.

  • Patent number: 8188385
    Abstract: A method and device for provisionally determining the mass of a vehicle when it is initialized. After initialization of the vehicle, the method determines a vehicle mass value by a static mass determination method and then checks whether this value is within a predetermined tolerance band around the dynamically last-determined vehicle mass value, which has been stored for that purpose. If this is so, and there has in the meantime been no significant change of the vehicle's mass, the previously stored dynamic vehicle mass value is probably more accurate and is used in the determination. Otherwise it can be assumed that the vehicle mass value has changed substantially, and the statically determined vehicle mass value is therefore used until a device for the dynamic determination of a vehicle mass can supply a more accurate vehicle mass value after a short time.

  • Patent number: 8185345
    Abstract: Described is a consumption monitoring device for monitoring the amount of consumables consumed by an animal during a monitoring period. More specifically, the consumption monitoring device measures the weight of the consumables, which are contained within a receptacle, and detects any change in the weight, such as when additional consumables are placed within the receptacle or when the animal consumes all or some of the consumables. The device calculates various values based on these changes in weight, at least one of which indicates the amount of consumables consumed by the animal. The device displays this calculated value such that the user is informed of the amount of consumables consumed by the animal within the monitoring period. This information assists the user in maintaining the animal on a desired feeding program.

  • Patent number: 8097820
    Abstract: A method of controlling a scale in connection with to a carrier of pourable bulk materials. The scale involved has a control with a display and control buttons. Upon a first press of a first control button, the system is transitioned into a “tare” mode and displays a base, or tare, value. Upon a second press of the first control button, generally after unloading some or all of the load, the difference in weight from the first press is saved to a storage medium, and a value displayed representing the weight of bulk material in the container at that time. The method may also include the pressing of a Zero button to zero the scale before the carrier is first loaded.

  • Patent number: 7996107
    Abstract: The invention relates to a device that comprises a tool holder that can be adjusted in an x-axis, a y-axis which is perpendicular thereto, and a z-axis that is perpendicular both to the x-axis and the y-axis and that can be pivoted about the z-axis. A dispense head for solid material is mounted on the tool holder as the tool. Two scales are disposed on the dispense head for solid material, said scales weighing the material which is or is to be delivered by the dispense head for solid material. The inventive design with two scales directly mounted on the dispense head for solid material allows for weighing of the material without the dispense head for solid material or the material having to be placed on separate scales.

  • Patent number: 7979185
    Abstract: A method for determining a motor vehicle mass which is implemented in conjunction with shifting an automated shift transmission from a current gear to a desired gear. In determining the mass, a value force and movement parameters are determined partly before or after the shift operation and partly during it. For the more rapid and accurate determination of mass, the drive-wheel-related traction force of the drive engine before and after the shift F_zug_vor, F_zug_nach, the longitudinal acceleration of the vehicle before and after the shift, a_zug_vor, a_zug_nach, and the acceleration a_roll determined in the traction-force-free phase during the shift are determined, and from these and in accordance with the equation m=F_zug/(a_zug?a_roll), a first mass value m_vor=F_zug_vor/(a_zug_vor?a_roll) is calculated for the beginning of the shift and a second mass value m_nach=F_zug_nach/(a_zug_nach?a_roll) is calculated for the end of the shift.
