摘要： To provide a dynamometer control device whereby excitation control can be performed so that a resonance phenomenon does not occur even when the moment of inertia of an engine is unknown. A dynamometer control device 6 is provided with an excitation signal generating unit 61 for generating a randomly or periodically fluctuating excitation signal, a speed controller 62 for generating an input signal to a dynamometer whereby a dynamo rotation speed matches a predetermined dynamo command rotation speed, a shaft torque compensator 64 for generating an input signal to the dynamometer whereby vibration of a shaft for connecting an engine and the dynamometer is suppressed using the detection value of a shaft torque sensor, and an adder 65 for generating a torque electric current command signal by adding the input signals generated by the speed controller 62 and the shaft torque compensator 64 to the excitation signal.

摘要： A weight distribution associated with an unmanned aerial vehicle (UAV) may be determined prior to dispatch of the UAV and/or after the UAV returns from operation (e.g., a flight). In some embodiments, one or more UAVs may be placed on or proximate to a physical metrics acquisition (PMA) device. The PMA device may include a grid or array of load cells may be used to determine a distribution of weight of the UAV at three or more points associated with the UAV. The distribution of weight may be used generate analytics, which may include a total weight of a vehicle, a center of mass of the vehicle (in two or more dimensions), power requirements of the UAV for a given flight task (e.g., how much battery power the UAV requires, etc.), and/or other analytics. In various embodiments, the PMA device may perform moment of inertia tests for the UAV.

摘要： A method of calibrating the torque outputs of a rheometer by using a calibrating object with a certified moment of inertia, measuring the moment of inertia of the calibrating object using the rheometer, and calculating the torque adjustment factor by dividing the certified moment of inertia value by the measured moment of inertia value. The torque adjustment factor is applied to correct subsequent measurements of rheological properties conducted using the rheometer. The torque adjustment factor may be double-checked for reproducibility by measuring the moment of inertia of the calibrating object, correcting it with the torque adjustment factor, and comparing it with its certified moment of inertia value.

摘要： The weight, balance point and swing weight of a sports implement such as a tennis racket can be automatically duplicated using a measuring unit and a computer program that uses data supplied by the measuring unit and data prestored in a database. The measuring unit measures the total weight of a raw tennis racket, the force it exerts when supported by the balance and a fixed point, and the period of oscillation of the tennis racket when swung as a pendulum. The computer calculates the weight of a molded handle to be formed on the raw racket and the weight and location of lead weights to be added to a finished racket made from the raw racket so that the finished racket meets the specifications prestored in the computer. The system thus enables a particular racket to be duplicated by matching the properties of the finished racket with prestored specifications of the particular racket.

摘要： Single ended tuning fork inertial sensor having a housing and a single ended tuning fork of a quartz-like material of a predetermined thickness, the tuning fork has first and second tines lying in a plane and having an axis of symmetry and has a body formed integral with said first and second tines. The body is rigidly secured to the housing. The tines have a rectangular cross section and have a width which is different from the thickness. The body has a stem formed therein which has a width less than that of the body. Drive electrodes are secured to the tines. An oscillatory frequency is supplied to the above drive electrodes to excite the tines in a drive mode and in the presence of an axial angular rate to cause the tines to operate in a pickup mode which is substantially separated in frequency from the drive mode. The width and thickness of the tines are chosen so as to provide a frequency difference between the frequency of the pickup mode and the frequency of the drive mode, and width and length of the stem are chosen so as to a reduce the frequency difference.
