Crystals: Introduction to US3840005Z Application Field and Working Principle

Crystals are highly potent substances with a wide range of applications. Their form is typically either a natural or synthetic form of solidified mineral, primarily composed of atoms arranged in an orderly, symmetrical pattern. Crystals have been used for centuries in many different fields and cultures for applications ranging from divination to healing to charging batteries. The US3840005Z patent, which was granted in 1995, brought a new and interesting application to crystals and has had far-reaching implications since its inception. In this patent, a method is described on how to use a crystal "piezo-resonant electric filter" to create a sound-field filter. This invention makes it possible to filter out background noise from an acoustic signal, resulting in an improved audio quality.The patent describes a device made of two or more piezoelectric crystals aligned along a common axis. These crystals are connected to two or more transducers or receivers, which are then connected to a balanced electrical bridge circuit and a low pass filter. The crystals are activated by the transducers, and depending on the application, they can amplify, filter and distort signals.When the crystals are pressed, their electric field is synchronized to the incident sound waves, which cause a force in the crystals that causes them to vibrate relative to the sound waves. These vibrations are then transferred to the transducers, which respond with a voltage proportional to the vibration frequency, producing a filtered sound-field. This US3840005Z filter system has been incorporated in many different audio, medical and industrial applications. In the audio field, these filters can be used to reduce background noise or to shape the tonal response of a sound system. In medical applications, the filter allows for precise readout of signals from various organs or tissues, and in the industrial setting it can be used to measure the motion and speed of any device.For example, the US3840005Z filter is used in the DICOM (Digital Imaging and Communications in Medicine) imaging system to help reduce or filter out unwanted background noise from ultrasound images. It also allows for profiling of organ motion from inside the body with improved accuracy. The piezo-resonant crystals in the US3840005Z filter system can also be used in vibration cancellation systems, which make use of the electrical interaction between two or more crystals to cancel out vibrations and noise. The application of this technology is most common in active noise cancellation systems, where microphones and specialized speakers are used to detect and produce a counter-frequency that cancels out the unwanted background noise.The US3840005Z patent has opened up a wide range of new possibilities that wouldn’t have been possible without it. Its impact on audio, medical and industrial applications has been tremendous, and its effects are likely to continue to reverberate in surprising new ways for many years to come.

Conclusion

Crystals and their piezo-resonant electric filter, as described in US3840005Z patent, have become a versatile and important tool in a variety of acoustic, medical and industrial applications. They can be used to reduce background noise from an acoustic signal, making it easier to pick out details and improve audio quality, as well as for profiling organ motion for precise readout. In addition, the filter can be used for vibration cancellation, which is especially useful for active noise cancellation systems. The US3840005Z patent has significantly expanded the use and impact of crystals in all these areas, and the possibilities are likely to continue to grow.
