Abstract: An electric horn (50) having a diaphragm (14) connected to a ferromagnetic plunger (16) is driven by an electromagnetic coil (36) to cause vibrations of the diaphragm (14) at the resonant frequency of the diaphragm and plunger combination. A solid state driver (58) has a timer (70) tuned essentially to the frequency of the diaphragm assembly and controls the driver power output to effect coil energization to drive the diaphragm movement synchronously with the timer frequency. The driver output stage comprises a power MOSFET (80) or a Darlington pair.

Abstract: Embodiments described herein relate to methods and apparatuses for controlling an operation of a vibrational output system and/or an operation of an input sensor system, wherein the controller is for use in a device comprising the vibrational output system and the input sensor system. A controller comprises an input configured to receive an indication of activation or de-activation of an output of the vibrational output system; and an adjustment module configured to adjust the operation of the vibrational output system and/or the operation of the input sensor system based on the indication to reduce an interference expected to be caused by the output of the vibrational output system on the input sensory system.

Abstract: A vibration generating device that can make a relatively heavy vibration member produce sufficient vibration. A vibration generating device has: a vibration member; multiple actuators that are connected to the vibration member; and a stationary element that supports the vibration member via the multiple actuators. Each of the multiple actuators comprises: a supporting body to which the vibration member is fixed; a movable element; a first elastic member that is connected to the supporting body and the movable element; and a magnetic drive circuit (a first magnetic drive circuit and a second magnetic drive circuit) that makes the movable element move linearly back and forth relative to the supporting body. The multiple actuators are supported by the stationary element via a second elastic member. The first elastic member and the second elastic member comprise a gelatinous silicone gel or the like.

Abstract: This disclosure is related to marine seismic sources, for example marine seismic sources known in the art as benders. Some embodiments of this disclosure use magnetic reluctance forces to produce seismic energy. For example, pole pieces may be attached to one or more plates of a marine seismic source, and a wire coil may induce an attractive force between the pole pieces to cause deformation of the plates to produce seismic energy. Such marine seismic sources may be components of a marine seismic survey system, and may be used in a method of marine seismic surveying. Methods of making marine seismic sources are also disclosed.

Abstract: A plurality of micro-electro-mechanical system (MEMS) transducers in a phased array are coupled to a flexible substrate using carbon nanotubes (CNTs) for conformal ultrasound scanning. Each transducer comprises a cantilever, magnetic material deposited on the cantilever, and a solenoid positioned relative to the magnetic material. The carbon nanotubes are grown on the cantilever and mechanically couple the transducer to one side of the flexible substrate. The other side of the flexible substrate is applied to a surface of a part under inspection, and the transducers are electrically connected to a processer to cause movement of the cantilevers when the solenoids are energized by the processor. The movement of the cantilevers results in movement of the carbon nanotubes, which imparts a force to the flexible substrate that results in ultrasound waves, which permeate the part. Returns from the ultrasound waves are interpreted by the processor to generate images of the part.
