Mass spectrometer
For a sample containing a target component, a product-ion scan measurement in which the m/z value of a known ion originating from the compound is designated as a precursor ion is performed in a measurement unit (1) to acquire profile spectrum data.

Electrical methods and systems for concrete testing
Hundreds of thousands of concrete bridges and hundreds of billions of tons of concrete require characterization with time for corrosion. Accordingly, protocols for rapid testing and improved field characterization systems that automatically triangulate electrical resistivity and half-cell corrosion potential measurements would be beneficial allowing discrete/periodic mapping of a structure to be performed as well as addressing testing for asphalt covered concrete. Further, it is the low frequency impedance of rebar in concrete that correlates to corrosion state but these are normally time consuming vulnerable to noise. Hence, it would be beneficial to provide a means of making low frequency electrical resistivity measurements rapidly. Further, prior art techniques for electrical rebar measurements require electrical connection be made to the rebar which increases measurement complexity/disruption/repair/cost even when no corrosion is identified. Beneficially a method of determining the state of a rebar without electrical contact is taught. |

Compact centrifugal apparatus for conveying a fluid
An improved centrifugal pump uses straight tubes or fluid channel members rather than expanding passages between the inlet and exit flow. In straight tubes a process occurs of building up of pressure faster than within the passages as the fluid attempts to expand due to the Coriolis force potentially acting against the centrifugal force to build up the pressure within and along the tube or fluid channel. Because the flow increases faster than increases in RPM a more compact pump is provided that can move more air and produce higher pressures than ordinary centrifugal pumps. Hence: 1) Flow increases proportional to tube area because a larger area means more air can be drawn into the tube; 2) Flow increases proportional to tube length because the exit pressure increases proportional to tube length; and 3) Flow increases faster than increases in RPM, thereby exhibiting a higher outflow pressure. |

The processor maintains the operation of the motor at the target rotating speed at that point by using the constant speed control method when the absolute value of rotating speed difference is within the range of the preset rotating speed difference. |

Electric pump and cleaning device for on-vehicle optical sensor
An electric pump includes a cylinder, a piston, a motor, and a discharge valve. The cylinder includes a valve port and a discharge port, which is in communication with the valve port. The discharge valve opens and closes the valve port. When the piston is moved forth to narrow a void in the cylinder, air is compressed in the cylinder. The discharge valve opens when operated by the piston that moves forth. The discharge valve opens and discharges compressed air from the valve port so that fluid including air is discharged from the discharge port. |

Micro-cathode arc thruster
A satellite thruster increases satellite efficiency. The Linear Actuated μCAT has a stepper motor to move the ablative electrode forward. A LabVIEW program and Arduino microcontroller are used to analyze the Linear Actuated μCAT to determine how many steps are required for re-ignition, arc current, and the validity of the feed system. Results from testing show that micro-stepping the stepper motor is an effective way to replenish the cannibalized electrode for propellant. |

Railcar fixtures for transportation of wind turbine blades and method involving same
A transport system for transporting a wind turbine blade on first and second railcars that serve as load cars. A root end fixture on the first railcar is connected to a root end portion of the wind turbine blade. A mid-frame fixture on the second railcar supports a reinforced midsection of the wind turbine blade using a pair of support saddles. A tip end fixture restrains a tip end portion of the wind turbine blade against lateral movement outside of a preselected range of movement in opposite lateral directions and causing bending of the blade about the mid-frame fixture when the restraint device imparts sufficient restraining force to the tip end portion of the blade. |

Method and system for controlling the active power output of a wind farm
A method for controlling an active power output in a wind farm comprises inputting a setpoint of the active power into a ramp and limiting unit to determine an internal active power setpoint. Inputting the internal active power setpoint into a distributing unit configured to calculate a modeled active power setpoint of the wind farm. Determine by a subtraction element, a control difference that is a difference between the modeled active power setpoint and an actual value of the active power output of the wind farm. Determine a controller setpoint variable and calculating an overall setpoint variable from the controller setpoint variable and the feed-forward control variable. Splitting the overall setpoint variable for models of the wind turbines and determining using the wind turbine models the modeled active power setpoint of respective wind turbines depending on a portion of the active power setpoint. |

Control device and control method for vehicle
A control device for a vehicle includes an electronic control unit. The electronic control unit executes control for prohibiting stop-and-start control until a predetermined period elapses after an ignition switch is turned ON. The electronic control unit executes scene-specific electric power supply control for operating a first function group that is a specific function and stopping a function other than the first function group in accordance with a state of the vehicle at a time when the ignition switch is turned OFF. The electronic control unit sets the predetermined period during which the stop-and-start control is prohibited longer in a case where the first function group is in an operating state than in a case where the first function group is not in an operating state when the ignition switch is turned ON. |
