摘要： A vibrational energy harvesting device is disclosed, which comprises first and second assemblies mounted on a base at a distance one from the other. The first assembly comprises vibrational means adapted to stretch under a straining force, whereby the device exhibits monostable quartic nonlinearity. The first and second assemblies comprise respective magnetised means in opposite polarity to one another, so that the second assembly exerts a repulsive magnetic force upon the vibrational means, whereby the device exhibits bistability. Both the monostable quartic and bistable nonlinearities can be independently controlled. A method of harvesting energy with the vibrational energy harvesting device is also disclosed.

摘要： A device is provided as part of a system, the device being for capturing vibrations produced by an object such as a musical instrument. Via a fixation element, the device is fixed to a drum. The device has a sensor spaced apart from a surface of the drum, located relative to the drum, and a magnet adjacent the sensor. The fixation element transmits vibrations from its fixation point on the drum to the magnet. Vibrations from the surface of the drum and from the magnet are transmitted to the sensor. A method may further be provided for interpreting an audio input, such as the output of the sensors within the system, the method comprising identifying an audio event or grouping of audio events within audio data, generating a model of the audio event that includes a representation of a timbre characteristic, and comparing that representation to expected representations.

摘要： A tuning device and method for tuning or verifying the tuning of a string of a stringed instrument is provided. The device includes an electromagnetic pickup physically separate from the stringed instrument. The electromagnetic pickup is a noise cancelling pickup. The electromagnetic pickup ultimately provides an electrical signal indicative of a movement of the string in a magnetic field of the electromagnetic pickup to a processor electronic tuner. Optional features of the electromagnetic pickup increase the effective range of the pickup.

摘要： The present invention is an extremely low frequency (ELF) microphone and acoustic measurement system capable of infrasound detection in a portable and easily deployable form factor. In one embodiment of the invention, an extremely low frequency electret microphone comprises a membrane, a backplate, and a backchamber. The backchamber is sealed to allow substantially no air exchange between the backchamber and outside the microphone. Compliance of the membrane may be less than ambient air compliance. The backplate may define a plurality of holes and a slot may be defined between an outer diameter of the backplate and an inner wall of the microphone. The locations and sizes of the holes, the size of the slot, and the volume of the backchamber may be selected such that membrane motion is substantially critically damped.

摘要： A contactless vibration meter having a magnetic strip, a detector, and a processor is disclosed. The N-pole blocks of the magnetic strip are unequal lengths and the S-pole blocks of the magnetic strip are also unequal lengths, the detector is detecting the N-pole blocks of the magnetic strip with unequal lengths and the S-pole blocks of the magnetic strip with unequal lengths, and the voltage variation due to the change of the magnetoresistance of the detector is calculated by the processor, so as to transfer to corresponding vibrating waveform, thereby being capable of obtaining the vibrating information of the tested object. It is not limited by the space of the factory or the pattern of the tested object, and capable of being attached to detect immediately.
