  • Publication number: 20180050086
    Abstract: Methods for improving the health of a female human or non-human animal are disclosed. The methods include the step of administering to the animal compositions including an effective amount of glycomacropeptide (GMP) for effectuating the methods. Specifically, the methods can be used to increase the rate of fat metabolism or fat oxidation, decrease percentage of body fat, increase the rate of bone mineralization, increase bone mineral content, increase bone mineral density, and/or increase bone strength in the animal. GMP-containing compositions can be used according to the disclosed methods to treat obesity and related metabolic conditions, or to treat or prevent osteoporosis, osteopenia, and other conditions related to loss of bone mineral content or bone strength.

  • Patent number: 9869996
    Abstract: An Internet of things (IoT) network for managing assembly of a multi-part product in a production environment. A user wears a device that provides a hands-free display of assembly instructions while the user is assembling the product. The user also wears sensors for transmitting data about the user's location within the production environment. Point of assembly sensors are disposed at locations within the production environment for transmitting data regarding where the product is and should be assembled. The product's parts also include sensors that transmit data regarding location of the parts and how they are assembled. A backend computer system stores product assembly information including the assembly instructions, where the user should be to assemble the product, how the product should be assembled, and verification of assembly accuracy. Alerts are generated if information from the sensors does not corresponding with the preprogrammed information in the computer system.

  • Patent number: 9533831
    Abstract: The conveyor belt monitor includes sensors and motion detectors for monitoring the condition of the conveyor belt of a conveyor belt system. The monitor includes upper and lower sensors respectively positioned above and below the lower belt of the conveyor to transmit warning of belt damage or other problem(s) while allowing the conveyor to continue operation. An additional switch above the upper sensor detects extreme belt damage, and shuts down the conveyor if such damage or condition(s) is/are detected. A motion sensor may also be provided to detect rotation of the upper roller and to transmit a warning of material carried on the lower or return belt surface that causes the roller to rotate. The monitor thus automatically warns of an anomalous condition while allowing the conveyor to continue to operate, or shuts down the conveyor in the event of an extreme condition(s).
