The second model represents another part of the process and comprises a second port to which other models may be connected. The system then connects the first port and the second port together. Upon connection, the system allocates a memory location as a connection variable that represents a type of information transfer between the first and second ports. A first port variable, which represents a value transferrable through the first port, is set to reference the value at the allocated memory location. Similarly, a second port variable, which represents a value transferrable through the second port, is also set to reference the value at the allocated memory location.

    Abstract: In one embodiment, a router operating in a hierarchically routed computer network may receive collected data from one or more hierarchically lower devices in the network (e.g., hierarchically lower sensors or routers). The collected data may then be converted to aggregated metadata according to a dynamic schema, and the aggregated metadata is stored at the router. The aggregated metadata may also be transmitted to one or more hierarchically higher routers in the network. Queries may then be served by the router based on the aggregated metadata, accordingly.

    Abstract: A system for comfort based management of thermal systems, including residential and commercial buildings with active cooling and/or heating, is described. The system can operate without commissioning information, and with minimal occupant interactions, and can learn heat transfer and thermal comfort characteristics of the thermal systems so as to control the temperature thereof while minimizing energy consumption and maintaining comfort. A thermal model represents thermal behavior of a volume in a thermal system, characterizing heat transfer and estimating energy consumption and temperature. A comfort model represents thermal comfort in a volume of a thermal system, estimating an effective temperature at which an occupant is unlikely to object.

  • Patent number: 10537051
    Abstract: A mounting machine determines whether or not there is running out of a component in a mounting process based on initial order information and the number of remaining components, and when the mounting machine determines that there is running out of a component, a modified order in which the determined component is preferentially mounted is set as the mounting order. In addition, during the mounting process when a component of a subsequent mounting target in the mounting order runs out, and a component later in the mounting order than the component does not run out, the component that does not run out is previously mounted on the board. Furthermore, the initial order which is indicated by the initial order information is set in advance as an order such that a component in the plurality of components that has a higher frequency of running out than another component is preferentially mounted.

  • Patent number: 10503544
    Abstract: In an example embodiment, a computer-implemented method is disclosed that computes, using one or more processors, a path slack value for each path of a set of paths of a functional computing model. Each path of the set of paths comprises a set of tasks and the path slack value of each path reflects a difference between a deadline and a latency of the path. The method further determines a priority of each task of the set of tasks of each path based on the path slack value of the path, and allocates, using the one or more processors and based on the priority of each task, the tasks of each of the paths of the set to corresponding computing units from a set of computing units of an architectural platform.

  • Patent number: 10462614
    Abstract: A wireless sensor system includes wireless sensor nodes, each including a sensor interface that interfaces with sensing circuitry, a wireless interface to communicate with a wireless access point, at least one processor, and memory. The memory has instructions stored thereon that, when executed by the at least one processor, cause the wireless sensor node to compare a group identifier received in a message at the wireless interface with a group identifier of the wireless sensor node. Based on determining that the group identifier received matches the wireless sensor node, a start time to trigger is set in the wireless sensor node according to a start time defined in the message. A local clock of the wireless sensor node is monitored. Based on determining that the local clock has reached the start time to trigger, sensor data are acquired through the sensor interface and transmitted on the wireless interface.

The method and system include a vortex flow meter coupled to a digital readout that displays the measured flow rate and trip point. The flow meter display includes input devices used to adjust the trip point. The system and method provide for sending signals via a custom relay to the semiconductor manufacturing apparatus which is adapted to terminate a processing operation or change the fluid flow if the trip point is tripped. The system and method also provide for sending an electrical signal to a computer by way of a data acquisition unit and a converter. The converter converts the signal to a communication protocol consistent with the computer network and provides fluid flow information and trip point data as a function of time to the computer which then displays such data graphically.
