  • Publication number: 20200001232
    Abstract: A system for carbon dioxide removal from product from a direct contact steam generation system is provided. The system comprises a direct contact steam generation system, a pressurized heat recovery system, and a CO2 separation system, wherein the direct contact steam generation system converts a gaseous, liquid or solid fuel, in the presence of oxygen, using a moderate water, to produce a mixed vapour stream to be then led into the pressurized heat recovery system to produce a partially condensed product, which is led into the CO2 separation system to reduce the CO2 content to produce a CO2-lean liquid product, and the pressurized heat recovery system utilizes latent heat of the mixed vapour stream to produce a lower pressure vapour stream from the CO2-lean liquid product exiting the CO2 separation system.

  • Publication number: 20190368956
    Abstract: A pressure sensing element includes a supporting substrate including a cavity. A device layer is bonded to the supporting substrate, with a diaphragm of the device layer covering the cavity in a sealed manner. A plurality of piezoresistors is coupled to the diaphragm. A plurality of metal stress equalizers is disposed on the device layer such that each stress equalizer is generally adjacent to, but separated from, a corresponding piezoresistor. A plurality of metal bond pads is disposed on the device layer. The plurality of stress equalizers are constructed and arranged to reduce thermal hysteresis of the pressure sensing element caused by stress relaxation of the metal bond pads during a cooling and heating cycle of the pressure sensing element.

  • Patent number: 10354309
    Abstract: Methods and systems for simulating a search, for the purpose of evaluating one or more scoring functions used in ordering item listings for presentation in a search results page are described. Consistent with some embodiments, a simulation platform includes a real-time simulation module that receives search result sets for search queries that result in the conclusion of a transaction. The result set is then processed by the simulation platform with one or more test scoring functions, such that the resulting position of the item listing that has resulted in the transaction can be compared with the actual position at which the item listing was displayed in the actual search results. For each test scoring function, an average rank shift metric is determined, and displayed, thereby providing a metric with which to base decisions about which scoring functions to use in the production system.

  • Patent number: 10221062
    Abstract: An improved microelectromechanical system (MEMS) pressure sensing device has an extended shallow polygon cavity on a top side of a silicon supporting substrate. A buried silicon dioxide layer is formed between the top side of the supporting substrate and a bottom side of a device layer. Piezoresistors and bond pads are formed and located on a top side of the device layer and produce measureable voltage changes responsive to a fluid pressure applied to the device layer. The purpose of the extend shallow polygon cavity is to improve the sensitivity or increase the span while keep a low pressure nonlinearity during shrinking the die size of the MEMS pressure sensing device die with corner metal bond pads having a keep-out distance to prevent a wire bonder from breaking the thin diaphragm.

  • Patent number: 10140339
    Abstract: Methods and systems for deriving a scoring function, for use in ordering a set of search results, are described. Consistent with some embodiments, a simulation platform includes an offline simulator module that receives search result sets for search queries that result in the conclusion of a transaction. The result set is then processed by the offline simulation platform to derive a set of weighting factors for use with one or more parameters in a parametric scoring function. The weighting factors are determined, for example, by specifying an equation setting one or more constraints and then solving the equation for the weighting factors.

  • Patent number: 9846096
    Abstract: Electrical and mechanical noise in a microelectromechanical system (MEMS) pressure sensor are reduced by the symmetrical distribution of bond pads, conductive vias and interconnects and by the elimination of bond wires used in the prior art to connect a MEMS pressure sensing element to an application specific integrated circuit (ASIC). The bond wires are eliminated by using conductive vias to connect an ASIC to a MEMS pressure sensing element. Extraneous electrical noise is suppressed by conductive rings that surround output signal bond pads and a conductive loop that surrounds the conductive rings and bond pads. The conductive rings and loop are connected to a fixed voltage or ground potential.
