Abstract: A device for making electrical connection to a reciprocating element, such as to a voice coil of an actuator. An electrical flow path utilizing the helical centering springs as a primary element in conducting current ensures reliable current flow to a reciprocating element and avoids high-speed flexing of brittle wires. Hard-wired connections are utilized only between stationary elements. A second double-coil actuator embodiment employs a coaxial, substantially co-extensive pair of springs as the input and return current flow paths for each actuator.

Abstract: The present disclosure belongs to the field of geological exploration, and particularly relates to a seismic acquisition system based on a frequency domain expansion MEMS sensor, aiming at solving the problem that vibration frequencies exceed the frequency range of the MEMS sensor due to strong vibrations and cross coupling of multi-frequency signals usually occurring in well logging while drilling. When the MEMS sensor suffers strong vibrations or the MEMS sensor that can be selected cannot ensure that the frequency requirement of a measurement signal is stably met, the frequency domain expander of the present disclosure expands the frequency domain of a detection signal, so that the MEMS sensor can measure strong vibrations and out-of-band frequencies to a certain extent, the application range of the seismic acquisition system is extended, and the anti-mutation capability of the seismic acquisition system is improved.

Abstract: In a first aspect, a Torpedo-type Support-Pile Module (SPM) is disclosed, which includes a panel for wet connection, a burial restrictor device, and a base jointly mounted to a Seismic Sensor Module (SSM), which houses a combination of a pressure sensor with particle velocity or particle acceleration sensors, in addition to inclination sensors. In a second aspect, a telescopic-type SPM is disclosed, which includes a panel for wet connection, a base jointly mounted to a SSM, and at least two cylindrical sections capable of being inserted into each other, thereby reducing the storage and transport volume of the SPM. The panel of any one of the SPMs is connected to a wet connector of a Subsea Seismic Data Acquisition Module (SSDAM), the SSDAM in turn providing power to the seismic sensors of the SSM during the seismic data capture. At the end of the capture, the seismic sensors send the acquired data to a memory located in the SSDAM, and the connection between the panel and the connector is finally disconnected. Also disclosed are seismic data acquisition methods and a seismic survey system, for the purposes of permanent marine seismic monitoring related to SPMs. Advantageously, this methodology has the possibility of applying part of the logistics described above in reverse, so that, at the end of the seismic data acquisition campaigns or even when convenient, the telescopic-type SPMs can be removed, freeing the seabed of such items and leaving the same as it was before installation.

Abstract: A system includes a tunneling device including a body assembly configured to move through an interior cavity of a tunnel. The system also includes a distributed communication and sensing system and a controller. The distributed communication and sensing system includes a first beacon coupled to the body assembly, and a second beacon positioned outside of the tunnel. The second beacon is communicatively coupled to the first beacon. The controller is configured to compare a first signal transmitted by the first beacon to a second signal transmitted by the second beacon, determine an environmental characteristic of the tunnel based on the first signal and the second signal, and determine an operating parameter for the tunneling device based on the environmental characteristic.

Abstract: This disclosure describes a system and method for generating images and location data of a subsurface object using existing infrastructure as a source. Many infrastructure objects (e.g., pipes, cables, conduits, wells, foundation structures) are constructed of rigid materials and have a known shape and location. Additionally these infrastructure objects can have exposed portions that are above or near the surface and readily accessible. A signal generator can be affixed to the exposed portion of the infrastructure object, which induces acoustic energy, or vibrations in the object. The object with affixed signal generator can then be used as a source in performing a subsurface imaging of subsurface objects, which are not exposed.

Abstract: There is described a method of making an acoustic sensor having a frequency response approximating a desired frequency response. The method comprises wrapping optical fiber around a core according to a wrapping pattern. The wrapping pattern is determined from an impulse response of the acoustic sensor. The impulse response is determined from the desired frequency response of the acoustic sensor.

Abstract: A system and method for a distributed earthquake analysis and reporting system are provided. The system includes a facility control system at a facility that obtains earthquake information sent from one or more seismic sensors, and sends the earthquake information over a network directly or indirectly to other facility control systems. The facilities which include the facility control systems can be owned/operated by different business organizations or by the same organization, in examples. The facility control system at each facility responds to received earthquake information from the other facility control systems by configuring building systems such as public address systems to warn building occupants, industrial machine controllers to stop machinery, and elevator controllers to stop elevators at a nearest floor and open its doors, in examples.
