The sound wave sensor includes a sounding body 2 that outputs a sound wave signal of a predetermined frequency, an echo body 3 opposed to the sounding body 2 in a direction in which the sounding body 2 outputs the sound wave signal, the echo body 3 being provided at a position where the sound wave signal resonates at the predetermined frequency; a slit 5 through which a sheet-like banknote 4 passes, the slit 5 being provided between the sounding body 2 and the echo body 3; and a resonance determination unit 6 that determines a resonant state of the frequency output from the sounding body 2. The resonance determination unit 6 determines a resonant state by detecting variation in power consumption of the sounding body 2.

摘要： Various approaches for assessing a part for a defect are disclosed and that are based upon SAW modes. In one embodiment, a part-under-test (120) is excited. One or more SAW modes (206) are identified in the frequency response (240/260) of the part-under-test (120). A SAW mode area (248/266) in the frequency response of the part-under-test (120) is compared with a baseline SAW mode area (238/258) of a baseline frequency response (230/250) (and which may be associated with an acceptable part). This comparison may be used to determine if the part-under-test (120) may be characterized defective in at least some respect.

摘要： Herein are described methods and systems for the automatic measurement of the mass of an object. An example method may begin with detecting by a computing device (such as a wearable computing device) an action that corresponds to a mass-measurement mode. In response to detecting the action, the computing device is caused to operate in the mass-measurement mode. The mass-measurement mode may involve receiving a motion-sensor signal from at least one motion sensor, determining a difference between a frequency-component magnitude of at least one given frequency component and a predetermined frequency-component magnitude, determining a mass of an object based on at least the determined difference between the frequency-component magnitude of the at least one given frequency component from the predetermined frequency-component magnitude, and causing an output device to provide an indication of the determined mass of the object.
