摘要： The invention discloses a bark detection method. An induction coil located in a magnetic field is arranged in a bark stop device worn on a head and neck part of a pet dog, and is configured to monitor a violent vibration action of a throat part of the pet dog. Violent vibration of the throat part of the pet dog during barking causes relative displacement between the magnetic field and the induction coil, so that the induction coil cuts magnetic lines of force of the magnetic field and generates an induction current. The induction current is collected and compared to judge whether the pet dog is barking or not. By using the induction current generated by the induction coil as a basis for judging whether the pet dog is barking or not, judging accuracy can be improved, and erroneous judgment is reduced to a great degree. The invention also discloses a bark detection device and a bark stop device with the device.

摘要： A method for detecting an oscillation of a vehicle part for a vehicle contains a step for applying an electric excitation signal to at least one electric coil. The at least one electric coil is inductively coupled to at least one position element. The at least one position element is coupled to the vehicle part. The method also contains a step for inputting an electric coil signal from the at least one electric coil. The electric coil signal is tapped at the at least one coil in response to the electric excitation signal and affected by the at least one position element. The method also contains a step for determining at least one property of the oscillation of the vehicle part based on the input electric coil signal.

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 geophone including a plurality of ferromagnetic masses (e.g., magnets) disposed to oscillate on one or more compliant elements (e.g., springs) in a manner that produces a steep flux gradient at one or more conductive coils is disclosed. The magnetic masses are positioned with like poles facing each other so as to compress the magnetic field gradient. The coils may be positioned in the flux gap either between the magnets, in close proximity to the magnets, or surrounding the magnets. Vibration measurements may then be detected from the movement of at least one of the magnetic masses.

摘要： The invention relates to a vibration measurement system for frequency-selective oscillation measurement in particular of low frequencies as are relevant in the field of automation and drive technology. The invention proposes coupling a broadband transmitter structure, which is excited directly by the excitation signal to be determined, via an electrostatic or inductive force to a receiver structure. This force coupling results in amplitude modulation of a carrier signal exciting the receiver structure. The actual excitation signal can be extracted from the spectrum of the amplitude-modulated carrier signal, for example by suitably selecting the frequency of the carrier signal. In order to make an oscillation analysis possible which is as unsusceptible to interference possible, an interference signal brought about, for example, by connector excitations is largely eliminated in advance from the amplitude-modulated carrier signal.
