  • Publication number: 20150006129
    Abstract: Generating a heat transfer model for building energy may comprise developing a PDE model that describes heat transfer through building envelope of a building, and developing an ODE model that describes the heat transfer and thermal balance in a space inside the building. Stepwise parameter estimation integrates the PDE model and the ODE model in generating the heat transfer model.

  • Publication number: 20150006127
    Abstract: A predictive model for building energy consumption may be constructed and run to predict energy consumption in a building or to detect anomaly in energy consumption in a building or combinations thereof. Historic energy consumption data associated with energy consumed in a building may be received. Enthalpy of air outside the building may be determined. An energy consumption model may be calibrated based on the historic energy consumption data and the enthalpy of air outside the building. The energy consumption model incorporates enthalpy difference between a balance enthalpy and the enthalpy of air outside the building.

  • Patent number: 8921952
    Abstract: Methods for fabricating crack resistant Microelectromechanical (MEMS) devices are provided, as are MEMS devices produced pursuant to such methods. In one embodiment, the method includes forming a sacrificial body over a substrate, producing a multi-layer membrane structure on the substrate, and removing at least a portion of the sacrificial body to form an inner cavity within the multi-layer membrane structure. The multi-layer membrane structure is produced by first forming a base membrane layer over and around the sacrificial body such that the base membrane layer has a non-planar upper surface. A predetermined thickness of the base membrane layer is then removed to impart the base membrane layer with a planar upper surface. A cap membrane layer is formed over the planar upper surface of the base membrane layer. The cap membrane layer is composed of a material having a substantially parallel grain orientation.

  • Patent number: 8922205
    Abstract: A magnitude and direction of at least one of a reset current and a second stabilization current (that produces a reset field and a second stabilization field, respectively) is determined that, when applied to an array of magnetic sense elements, minimizes the total required stabilization field and reset field during the operation of the magnetic sensor and the measurement of the external field. Therefore, the low field sensor operates optimally (with the highest sensitivity and the lowest power consumption) around the fixed external field operating point. The fixed external field is created by other components in the sensor device housing (such as speaker magnets) which have a high but static field with respect to the low (earth's) magnetic field that describes orientation information.

  • Publication number: 20140374851
    Abstract: A method (60) entails providing a substrate (34) with a structural layer (30) having a thickness (40). A partial etch process is performed at locations (82) on the structural layer (30) so that a portion (92) of the structural layer (30) remains at the locations (82). An oxidation process is performed at the locations which consumes the remaining portion of the structural layer and forms an oxide (36) having a thickness (42) that is similar to the thickness (40) of the structural layer (30). The oxide (36) electrically isolates microstructures (28) in the structural layer (30), thus producing a structure (22). A device substrate (120) is coupled to the structure (22) such that a cavity (48) is formed between them. An active region (44) is formed in the device substrate (120). A short etch process can be performed to expose the microstructures from an overlying oxide layer (110).

  • Patent number: 8883535
    Abstract: Methods for the fabrication of a Microelectromechanical Systems (“MEMS”) device are provided. In one embodiment, the MEMS device fabrication method includes forming a via opening extending through a sacrificial layer and into a substrate over which the sacrificial layer has been formed. A body of electrically-conductive material is deposited over the sacrificial layer and into the via opening to produce an unpatterned transducer layer and a filled via in ohmic contact with the unpatterned transducer layer. The unpatterned transducer layer is then patterned to define, at least in part, a primary transducer structure. At least a portion of the sacrificial layer is removed to release at least one movable component of the primary transducer structure. A backside conductor, such as a bond pad, is then produced over a bottom surface of the substrate and electrically coupled to the filled via.

    Abstract: A micro or nano electromechanical transducer device formed on a semiconductor substrate comprises a movable structure which is arranged to be movable in response to actuation of an actuating structure. The movable structure comprises a mechanical structure having at least one mechanical layer having a first thermal response characteristic, at least one layer of the actuating structure having a second thermal response characteristic different to the first thermal response characteristic, and a thermal compensation structure having at least one thermal compensation layer. The thermal compensation layer is different to the at least one layer and is arranged to compensate a thermal effect produced by the mechanical layer and the at least one layer of the actuating structure such that the movement of the movable structure is substantially independent of variations in temperature.
