摘要： Adaptive operations of a first noise control system and a second noise control system may include a speaker that outputs noise cancellation sound, a microphone that detects an error signal, an auxiliary filter that generates, from a noise signal, a correction signal that corrects the error signal so that a difference in a position between the microphone and a noise cancellation position is compensated, and an adaptive filter that performs an adaptive operation using the corrected error signal to generate the noise cancellation sound from the noise signal are alternately performed. A transfer function learned in a state in which the second noise control system is stopped is set in the auxiliary filter of the first noise control system, and a transfer function learned in a state in which the adaptive operation of the first noise control system is stopped is set in the auxiliary filter of the second noise control system.

摘要： A power generation body includes a first member, a second member, and a packaging body. The first member includes a first insulating film that forms a first surface. The second member includes a second insulating film that forms a second film that opposes the first surface and comes into contact with the first surface. The packaging body hermetically seals the first member and the second member. The first member and the second member are configured such that a real contact surface area between the first surface and the second surface changes according to pressure applied to the first member and the second member, and one of the first insulating film and the second insulating film is positively charged and the other is negatively charged due to the real contact surface area changing.

摘要： A power generation body includes a first member, a second member, and a cushioning material. The first member includes a first insulating film that forms a first surface. The second member includes a second insulating film that forms a second surface that opposes the first surface and comes into contact with the first surface. The cushioning material is arranged on a side opposite to the first surface of the first member. The first member and the second member are configured such that a real contact surface area between the first surface and the second surface area changes according to pressure applied to the first member and the second member, and one of the first insulating film and the second insulating film is positively charged and the other is negatively charged due to the real contact surface area changing.

摘要： A device is used in combination with a fluid pressure source and a replaceable sampling tube having a pointed cannula section and a hollow for capillary blood collection. The device is provided with: a body defining a bore extending along an axis; a first flow path in fluid communication with the fluid pressure source; a rotor fitting in the bore and being capable of spinning in both directions about the axis; a boss section extending along the axis and so dimensioned as to rotatably support the sampling tube coaxially with the axis and expose the cannula section out of the boss section; and a detachable fastening binding the sampling tube to the rotor so as to set the sampling tube into rotation concentric with the axis and establish fluid communication between the first flow path and the hollow of the sampling tube.

摘要： To estimate the top surface of a measurement target on the basis of a data point group that corresponds to the top surface of the measurement target and is obtained using a laser scanner. A data processing unit: selects two data points from the data point group which is contained within the thickness in the vertical direction of a hoisting load region, and calculates the distance between the selected two data points; determines the two data points are located in the same plane and calculates the gravitational center for each point determined to be in the same plane when the distance between the two points is equal to or less than a threshold; searches for a nearby point which is a data point for which the distance from the gravitational centers is equal to or less than the threshold, determines the nearby point is also in the same plane when the nearby point is discovered, and repeatedly performs the process in order each time a nearby point is discovered; obtains multiple data points determined to be in the same plane; and estimates plane clusters representing the top surfaces of a hoisting load and an object on the basis of the multiple data points.
