摘要： The present invention provides a new and unique method, sensor, and apparatus for performing a seismic survey of an earth formation in relation to a borehole. The method includes arranging at least one strain seismic sensor in conjunction with a borehole structure, and mechanically coupling the borehole structure to the borehole to allow seismic data to be accurately transferred to the sensor. The sensor is preferably a fiber optic sensor, including a Fiber Bragg Grating which may be coupled to a relevant borehole structure in a number of ways.

摘要： A loudspeaker system containing wave-shaping sound chambers with approximately rectangular inlets and outlets of substantially the same size that are used to flatten or control the curvature of the acoustic wavefronts contained within system waveguides. Control of the degree of curvature of the wavefront enables the development of a wide variety of multi-waveguide arrays. The sound chambers are placed between a waveguides and a flattened conical horns of secondary waveguides. The sound chambers transform the curvature of the typical fan shaped wavefront that results from a conical horn throat into a wavefront that approximates a planar or curved rectangular ribbon of sound.

摘要： A sound attenuating system is provided which allows a relatively unobstructed airflow conduit to be associated with chambers that reflect various frequencies of sound back towards the source of the sound. The chambers are arranged in a coaxial association with the primary airflow conduit and are sized to reflect a certain range of frequencies of sound. Holes extend through the airflow conduit, in a radial direction, to place the airflow conduit in fluid communication with the chambers which surround portions of the conduit.

摘要： A suction muffler in a reciprocating compressor is installed over a suction valve to attenuate complex sound pressure (noise) such as vibrational noise, valve sonance, flowing noise and pulsative noise produced from the suction valve when low temperature, low pressure refrigerant gas ejected from an evaporator is sucked into a cylinder via the suction valve and a suction portion of the cylinder. A Tesla valve having two distribution paths is mounted in the suction muffler to attenuate the complex sound pressure (noise) while preventing the reflow of the refrigerant gas into the suction muffler from the suction valve. As a result, the Tesla valve also enhances the cooling ability of the compressor and the attenuation effect.

摘要： A multi-purpose device for use in a wide variety of circumstances including at sporting events. The device can (1) serve as a hat or headgear, (2) it can amplify a user's voice, (3) it can be used as a hearing aid, (4) it can be used as a carrying utensil, (5) it can serve as a banner to advertise a logo, (6) it can be used as a traffic safety cone, and (7) it can serve as a Christmas ornament. The device is tubular in shape; however, the tube is larger at one end than at the other end. The small end is about the size of mouth piece and the large end is several times larger than the small end. The device is made of a soft material that can fold and the inside of the device has sound reflective properties. The device is made of semi-flexible material that can support its own weight when held at the ends.

摘要： A fuel tank with a baffle disposed therein is disposed at an intermediate place between the two ends of the tank is provided for preventing noise caused when fuel shifts in the fuel tank from one end to the other. In a preferred embodiment, the baffle is constructed of a fiberglass filter media material. Also in a preferred embodiment, the baffle is collapsible so that it can be inserted into an opening in the top of a plastic fuel tank and then allowed to return to its original larger height whereby it will be held by a biasing pressure in a desired position within the tank.

摘要： An acoustic resistor or damper and method of manufacturing the same is disclosed. The damper has mesh material and mounting material attached to the mesh material. The mounting material defines an open region for transmission of sound through the mesh material, and has a mounting surface for mounting the damper on a surface surrounding an acoustic port or tube. The mounting surface is located on a plane different from the mesh material, thereby shielding the mesh material from adhesive applied between the mounting surface and the surface surrounding the acoustic port or tube. The method of manufacturing an acoustic damper comprises exposing emulsion applied to a mesh material through at least one opening in a photographic mask to ultraviolet light and removing the emulsion exposed. A portion of the remaining emulsion and mesh material is cut in a shape surrounding the removed emulsion.
