  • Patent number: 11621390
    Abstract: A contact sensor for the repeatable detection of small, high frequency mechanical vibrations in external systems is presented herein. The sensor includes a metal housing with an attachment device at one end and an output at the other end. Inside the metal housing is a core assembly that includes a piezo transducer assembly suspended or isolated between an actuator and a biasing device. The actuator may be in the form of a ceramic sphere that sits at least partially within a recess on the inside of the housing and is in physical contact with the piezo transducer assembly. The biasing device may be in the form of a spring that causes the piezo transducer assembly to be pressed against the actuator at a contestant and known amount of tension.

  • Patent number: 7233243
    Abstract: Method of ingress or egress intrusion detection by ultrasound surveillance throughout volumetric multi-area room around a protected object, where the surveyed room is arranged in juxtaposed volumetric closed or open areas that represent central, short-range and long-range echelons of defense-in-depth intrusion protection infrastructure. The used techniques of ultrasound intrusion detection are based on the phenomena of reflection, refraction by edge diffraction, and interference by shadowing of ultrasonic beams. The ultrasonic beam patterns are closely disposed in 2-D curvilinear or polygonal array, or in 3-D curved surface lattice over multilevel substantial openwork frames of different echelons. The informational and processing inter-echelon interrelation is being treated by control software algorithm that features situational logic transition driven by IF-THEN operator.

  • Publication number: 20050151644
    Abstract: Method of ultrasound intrusion detection is disclosed wherein the ultrasound multi-area volumetric surveillance is being organized to meet properly the correspondent requirements for the defense-in-depth protection of critical objects. All the room around a protected object is being purposely arranged in juxtaposed volumetric areas, which areas are closed or open and do represent respectively the central, short-range and long-range echelons of an entire defense-in-depth protection space. The pertain method of ultrasound detection of either ingress or aggress hazardous intrusion is being realized in each adjacent echelon regarding the specific task, which this very echelon has been commissioned with.

  • Publication number: 20050049498
    Abstract: In the case of disease in the respiratory organs of creatures, which especially inhabit in terms of overcrowding, the danger of spreading a disease throughout the entire breeding farm is perfectly evident. The use of traditional methods, such as the stethoscope, for examining the respiratory organs of each creature, in the mode of their direct contact listening, is impossible in most due to the specific spatial arrangement of creatures in breeding farms and/or infectious danger to a veterinary. Moreover, the acoustic signs of the said illness at its early stage cannot be heard audibly with use of traditional methods.

  • Publication number: 20040244854
    Abstract: Method of converting and amplifying a weak pneumatic signal into an enhanced hydraulic signal comprises a few of interrelated techniques: keeping free planar liquid high-speed jet-stream flow in steady-state compact quasi-parallelepipedic shape along its trajectory of free path throughout gas ambient of pneumatic control chamber; dividing pneumatic control chamber into two isolated cavities by said jet-stream flow and separating said pneumatic chamber from downstream adjacent intake hydraulic chamber by solid partition, slotted with jet stream passing channel; insulating low pressurized said control pneumatic chamber from highly pressurized said hydraulic intake chamber by forming locking liquid whirls in gaps between entire liquid side free surfaces of jet-stream flow and adjacent solid side surfaces of jet-stream passing channel; enhancing an impact of liquid jet-stream flow impulse upon output channels of intake hydraulic chamber by effecting thereupon with additional impulses of thrust reactive flows; cre
