Abstract
An apparatus includes a vibration sensor and an asymmetric damper. The apparatus includes a housing enclosing the vibration sensor coupled to an asymmetric damper. The vibration sensor is mechanically pressed, or compressed, against a target surface through the damper and the housing, under a spring.
Claims24
An apparatus, comprising:
- a vibration sensor, and
- an asymmetric damper affixed to a housing enclosing the sensor and damper, wherein the sensor, through the damper and the housing, under a spring, is mechanically pressed against a target surface.
A damper assembly, comprising:
- at least one portion enclosing the vibration sensor and having a hole for allowing a vibration sensor to pass through to a target surface;
- at least two protuberances, arranged asymmetrically, extending from the portion enclosing the vibration sensor, each holding and affixed to a mass, wherein the portion and protuberances are connected;
- and
- a spring permanently attached between a cover and a sensor holding piece within the portion;
- wherein the sensor holding piece is permanently attached to a first end of the spring and an opposite side of the sensor holding piece is permanently attached to a base of the vibration sensor and the cover is mechanically attached to the portion, thereby holding the vibration sensor against the target surface while attached to the portion.

An apparatus, comprising:
- means for sensing vibration;
- first means for reducing resonance and frequency shifting remaining resonance outside of a frequency range of concern between approximately 0 Hz and approximately 100 Hz, wherein the means for reducing resonance and frequency shifting is mechanically coupled to the means for sensing vibration;
- and
- means for housing the means for sensing vibration and the means for reducing resonance and frequency shifting, wherein the means for housing includes a second means for resonance reduction and frequency shifting remaining resonance outside of a second frequency range of concern between approximately 0 Hz and approximately 300 Hz and wherein the means for housing is mechanically coupled to the first means for reducing resonance and frequency shifting.
