Vibrating reed selective signaling system

Electrical Engineering, 1949
IN MANY mobile radio systems now in service, the car is provided with a loud-speaker which is in operation at all times, the desired car being called by voice. Such an arrangement has the disadvantage that the occupants of all the telephone-equipped cars hear all conversations on their channel.

Vibration Signal Transmission in Spider Orb Webs

Science, 1981
Vibration transmission from the prey-catching region to the hub of the unloaded orb web of Nuctenea sclopetaria was measured by laser vibrometry. Compared to transverse or lateral vibrations, longitudinal vibration shows less attenuation and contains more directional information.

Auditory display of knee-joint vibration signals

The Journal of the Acoustical Society of America, 2001
Sounds generated due to rubbing of knee-joint surfaces may lead to a potential tool for noninvasive assessment of articular cartilage degeneration. In the work reported in the present paper, an attempt is made to perform computer-assisted auscultation of knee joints by auditory display (AD) of vibration signals (also known as vibroarthrographic or VAG ...

Identifying Rogating Blades Vibration From the Shaft Torsional Vibration Signals

Aging Management and Component Analysis, 2003
This paper presents results from an experimental study on the identification of rotating blades vibration from the shaft torsional vibration signals. Test rigs that contain 12 blades bladed disk with shaft equipped with lateral and torsional vibration measurement is designed and manufactured.

[Meniscus signals in vibration arthrography].

Zeitschrift fur Orthopadie und ihre Grenzgebiete, 1987
The technique of vibration arthrography (VAG) permits the non-invasive evaluation of internal derangements of the knee. Using the computer-assisted recording and analysis equipment which has previously been described, a major survey was conducted into the signal patterns present in subjects with symptomatic knee joints.

Sonification of knee-joint vibration signals

Proceedings of the 22nd Annual International Conference of the IEEE Engineering in Medicine and Biology Society (Cat. No.00CH37143), 2002
Sounds generated due to rubbing of knee-joint surfaces may be a potential tool for noninvasively assessing articular cartilage degeneration. In this paper, an attempt is made to perform computer-assisted auscultation of knee joints by auditory display (AD) of the vibration signals (also known as vibroarthrographic or VAG signals) emitted during active ...

Copulatory Courtship with Vibrational Signals

2019
Most research on sexual communication with substrate-borne vibrational signals has focused on the early stages of the reproductive process—mate localization and pair formation. Here, I report the results of a literature review that suggests that vibrational signals are commonly used in male–female interactions during and after copulation, either by ...

Method of Generating Vibration Test Signals

Measurement Techniques, 2017
Possible ways of implementing vibration test signals are described. A method for generating such signals is proposed by adjusting the amplitudes of the individual harmonic components of the vibration signal. The results of modeling are presented.

Nonlinear vibration characterization by signal decomposition

Journal of Sound and Vibration, 2007
Abstract Methods for nonlinear vibration characterization by decomposing dynamic responses using the Hilbert–Huang transform and a sliding-window fitting technique are presented. Numerical results show that Hilbert–Huang transform can be used for decomposing nonlinear/non-stationary signals in order to reveal and estimate nonlinear effects.
