  • Publication number: 20170017895
    Abstract: A parameter-based multi-model blending method and system are described. The method includes selecting a parameter of interest among parameters estimated by each of a set of individual models, running the set of individual models with a range of inputs to obtain a range of estimates of the parameters from each of the set of individual models, and identifying, for each of the set of individual models, critical parameters among the parameters estimated, the critical parameters exhibiting a specified correlation with an error in estimation of the parameter of interest. For each subspace of combinations of the critical parameters, obtaining a parameter-based blended model is based on blending the set of individual models in accordance with the subspace of the critical parameters, the subspace defining a sub-range for each of the critical parameters.

  • Publication number: 20170016866
    Abstract: A gas sensing device includes a dielectric substrate, a heater integrated into a first side of the substrate and an insulating dielectric formed over the heater. A gas sensing layer is formed on a second side of the substrate opposite the first side. Contacts are formed on the gas sensing substrate. A noble material is formed on a portion of the gas sensing layer between the contacts to act as an ionizing catalyst such that, upon heating to a temperature, adsorption of a specific gas changes electronic properties of the gas sensing layer to permit detection of the gas.

  • Publication number: 20170011089
    Abstract: An embodiment includes dividing a map into a first grid comprising a first plurality of cells with a first resolution and into a second grid comprising a second plurality of cells with a second resolution; determining that, because an initial portion of a key of a first cell of the second grid comprises a key of a first cell of the first grid, the first cell of the first grid comprises the first cell of the second grid; storing the first and the second grid in memories of distributed servers, wherein the first cell of the first grid and the first cell of the second grid are stored in a same one of the distributed servers or are stored in neighboring ones of the distributed servers; and directing respective processors of the distributed servers to perform a parallel search of the first grid and the second grid using the keys.

  • Patent number: 9470645
    Abstract: A salt-based method to monitor and log the time periods a data center air's relative humidity goes above a predefined limit. The choice of the salt is such that its deliquescent relative humidity is equal to the desired limit, so that above the desired limit, the salt gets wet and therefore electrically conductive. An alarm can then give notice that relative humidity levels are above acceptable levels so that remedial action may be taken before problems such as electronic malfunction develop.

  • Publication number: 20160231171
    Abstract: The present invention discloses a spectrometer apparatus comprising a mobile device including an integrated camera, having a camera lens and an image sensor. The camera lens is located within a body of the mobile device that comprises a detachable housing coupled to the body of the mobile device. The detachable housing includes a first end and a second end opposed to the first end. The first end includes an optical input and the second end includes an opening that is substantially aligned with the camera lens. An optical spectrometer device is located within the housing and optically coupled to both the optical input at the first end of the housing and the camera lens at the second end of the housing. The optical spectrometer device receives a target image from the optical input and generates a spectral image that is received by the image sensor via the camera lens.

  • Patent number: 8823535
    Abstract: Apparatus and method for directly detecting the atmospheric conditions leading to creep corrosion of printed circuit boards (PCBs) well before the PCBs in the computers start suffering from creep corrosion. The embodiment indicates the propensity of the air towards creep corrosion on PCBs. Additionally, to avoid the false reading due to condensed moisture, condensed moisture may be avoided by using a heater attached to the creep corrosion monitor that keeps the creep corrosion monitor above the dew point temperature.
