20130166641 | POWER OUTAGE DETECTION SYSTEM FOR SMART GRID USING FINITE STATE MACHINES - A power outage detection system. The system includes a device configured to increment a reboot counter when the device is powered up, and to transmit a first message when the device loses power and a second message when the device is powered up, and a back office system. The first message includes the value of the reboot counter and a timestamp, and the second message includes the value of the reboot counter. The back office system includes a finite state machine configured to receive the first and second messages. The finite state machine determines if the received first message is valid using the value of the reboot counter and the timestamp, and determines if the received second message is valid using the value of the reboot counter. The finite state machine then outputs an accurate indication of the state of the device. | 06-27-2013 |

20100157302 | LIQUID FUEL PROPERTY DETECTION SYSTEM - A liquid fuel property detection apparatus includes a fuel passage, a light emitting device for emitting a light including a plurality of predetermined wavelengths toward the fuel in the passage, a light receiving device for receiving the light passing through the fuel, and a calculation unit for calculating the concentration of at least one of aroma, paraffin and olefin, which are hydrocarbon component components contained in the fuel. The calculation unit calculates the concentration of a specific component, which is one of aroma, paraffin and olefin, based on the reference transmittance of light in the specific component and the actual transmittance calculated from the amount of light emitted by the light emitting device and the amount of light received by the light receiving device with respect to each wavelength of the light. | 06-24-2010 |

20080246955 | Method of detecting alcohol concentration and alcohol concentration detecting apparatus - In a detection of an alcohol concentration, a first light and a second light are irradiated to a mixed liquid including a fossil fuel, an alcohol, and water, and the alcohol concentration is calculated based on amounts of the first light and the second light permeated through the mixed liquid. In the detection, a difference of a transmittance of the fossil fuel with respect to the first light and each transmittance of the alcohol and water with respect to the first light is larger than a first value. In addition, a difference of a transmittance of water with respect to the second light and each transmittance of the fossil fuel and the alcohol with respect to the second light is larger than a second value. | 10-09-2008 |
20100059020 | FUEL SUPPLY SYSTEM AND FUEL SUPPLY CONTROL METHOD FOR INTERNAL COMBUSTION ENGINE - At the time of shifting a fuel property value associated with a first imaginary passage cell as a fuel property value associated with a second imaginary passage cell located on the downstream side thereof, the fuel property value associated with the second imaginary passage cell is corrected in a controller by computing a difference between the fuel property value associated with the first imaginary passage cell and the fuel property value associated with the second imaginary passage cell and multiplying the difference by a correction coefficient. A stoichiometric air/fuel ratio is computed in the controller based on the fuel property value, which is associated with a last one of the imaginary passage cells. Fuel injection of an injector is controlled by the controller based on a computed injection quantity of fuel, which is computed based on the stoichiometric air/fuel ratio. | 03-11-2010 |
