  • Patent number: 8077543
    Abstract: A method and apparatus implementing a technique for mitigating noise in seismic data are presented. The technique includes estimating a noise component in a set of multicomponent seismic data representing a recorded wavefield from the relationship at the free surface of an upgoing component and a downgoing component decomposed from the recorded wavefield; and removing the estimated noise component from the seismic data. The noise component can be estimated by decomposing a recorded wavefield into an upgoing component and a downgoing component and isolating a noise component in the recorded wavefield from the relationship of the decomposed upgoing and downgoing components at the free surface.

  • Patent number: 8072841
    Abstract: A method for generating a synthetic seismogram. In one implementation, a ray tracing may be performed on a subsurface. The ray tracing may generate a plurality of rays. A first seismic wavefront may be reconstructed by triangulating a first plurality of control points that correspond to the plurality of rays. Each control point may represent an end point of a ray at the first seismic wavefront. The plurality of rays may be propagated to a second seismic wavefront. The second seismic wavefront may have a hole associated with at least one missing ray at the second seismic wavefront. A plurality of points on a circle may be defined that correspond to a second plurality of control points defining the hole. The second seismic wavefront may be reconstructed based on the plurality of points on the circle.

  • Patent number: 8068384
    Abstract: A method and system for processing synchronous array seismic data includes acquiring synchronous passive seismic data from a plurality of sensors to obtain synchronized array measurements. A reverse-time data process is applied to the synchronized array measurements to obtain a plurality of dynamic particle parameters associated with subsurface locations. These dynamic particle parameters are stored in a form for display. Maximum values of the dynamic particle parameters may be interpreted as reservoir locations. The dynamic particle parameters may be particle displacement values, particle velocity values, particle acceleration values or particle pressure values. The sensors may be three-component sensors. Zero-phase frequency filtering of different ranges of interest may be applied. The data may be resampled to facilitate efficient data processing.

  • Patent number: 8068982
    Abstract: An on-vehicle navigation system reliably performs guidance of a necessary exiting authorized section while avoiding the guidance of a needless exiting authorized section on a plural-lane road having a normal lane and a special lane where advancing from the normal lane in a predetermined advancing authorized section and exiting to the normal lane in a predetermined exiting authorized section are authorized. After discriminating whether the vehicle is driving in the special lane of the plural-lane road based on whether a characteristic object has been detected by a characteristic object detecting section, the guidance of an exiting authorized section is avoided in the case where the vehicle deviated from a recommended route including a special lane, and the guidance of an exiting authorized section is performed in the case where the vehicle deviated from a recommended route not including a special lane and drives in a special lane.

  • Patent number: 8054933
    Abstract: An injection system designed to deliver a chemical solution into a reactor through feedwater system taps during normal operating condition of a power reactor is disclosed. The process of delivery is via positive displacement pumps. Injection of chemical is in a concentrated solution form, which is internally diluted by the system prior to discharging from the skid. The injection system minimizes chemical loss due to deposition on the transit line, enables a higher concentrated solution to be used as the injectant, eliminates the time consuming laborious process of chemical dilution, raises chemical solution to the pressure required for injection, prevents solid precipitations out of solution at the injection pump head through the use of a flush solution, and deposits fresh chemical on new crack surfaces that develop during a power reactor start-up, shutdown and operation.

  • Patent number: 8046127
    Abstract: A vehicle-mounted electronic control apparatus can perform a variety of abnormality detections while reducing the control load of a microprocessor in the abnormality detection of a volatile backup memory that is backed up by an on-board battery. The apparatus includes a control CPU which is fed with power from a main power supply circuit upon closure of a power switch, a nonvolatile control memory and a backup memory. Even if the power switch is opened, the backup memory, being a partial area of a RAM memory, is fed with power through an auxiliary power supply circuit connected directly to the battery. When the battery is replaced with a new one and connected again, a power supply interruption monitoring memory is reset. At the start of operation of the control CPU, the backup memory is initialized based on reset information, and the power supply interruption monitoring memory is rewritten into a set state.

  • Patent number: 8046126
    Abstract: The start control is repeatedly performed for an oil pump that pressure feeds the flow of oil in a motor cooling system. This control is repeated for every specified rise in motor temperature (e.g., every 10° C.) from an initial starting temperature. This arrangement increases the potential for a successful start-up of the oil pump even when the oil has a high viscosity due to a relatively low outside air temperature. In the event of a failed start-up of the oil pump by repeated starting, the start control determines an abnormality exists in the oil pump or its power supply if an outside air temperature is greater than a reference temperature. This arrangement effectively eliminates incorrect detection of an abnormality in the oil pump or its power supply.
