  • Patent number: 9714853
    Abstract: A microfluidic flow rate sensor includes a droplet within a channel and a droplet movement detector that generates a signal based on the position and/or movement of the droplet within the channel. A processor determines the flow rate of a fluid through the channel based on the signal received from the droplet movement detector. In one example, the droplet movement detector is an optical detector, such as a combination of a lens and an image capturing device. In other examples, the droplet is electrically conductive, and at least a portion of the channel is conductive or includes electrical contacts. The position of the droplet within the channel is determined by observing the electrical characteristics of the channel.

  • Patent number: 9696283
    Abstract: In one embodiment, a photoacoustic effect measurement instrument for measuring a species (e.g., a species of PM) in a gas employs a pair of differential acoustic cells including a sample cell that receives sample gas including the species, and a reference cell that receives a filtered version of the sample gas from which the species has been substantially removed. An excitation light source provides an amplitude modulated beam to each of the acoustic cells. An array of multiple microphones is mounted to each of the differential acoustic cells, and measures an acoustic wave generated in the respective acoustic cell by absorption of light by sample gas therein to produce a respective signal. The microphones are isolated from sample gas internal to the acoustic cell by a film. A preamplifier determines a differential signal and a controller calculates concentration of the species based on the differential signal.

  • Patent number: 9696152
    Abstract: It is possible to, with a position measuring apparatus in a NC machine tool, a NC lathe, or the like that uses a load monitoring scheme, significantly reduce a response delay on the detecting jig side than those in the conventional apparatuses, and consequently measure the position of a measurement target with high accuracy. A measurement target (e.g., an advanceable and retractable center) is caused to abut a position detecting jig at the advanced end of the measurement target. In such a state, retracting and advancing motions of the measurement target are created to increase the load torque of a feed motor to a level sufficiently higher than the load torque that is detectable by the apparatus. After that, the abutment state between the measurement target (center) and the jig is canceled to cause a sudden drop in the load torque of the feed motor.
