Abstract: Learning personal audio systems and methods are disclosed. A learning personal audio system characterizes the digitized ambient sound so as to generate feature data for the digitized ambient sound, instructs a network interface to transmit the feature data to the remote server, requests one or more appropriate sound profiles from the remote server based upon the feature data, receives one or more selected sound profiles, selected by the remote server based upon the feature data, and initiates processing of the digitized ambient sound based upon the one or more selected sound profiles received from the remote server to generate digitized processed sound. The one or more selected sound profiles for the learning personal audio system are based upon sound profiles which are manually selected by a plurality of other users of personal audio systems similar to the learning personal audio system.

Abstract: An earpiece for real-time audio processing of ambient sound includes an ear bud that provides passive noise attenuation to the earpiece such that exterior ambient sound is substantially reduced within an ear of a wearer, an exterior microphone that receives ambient sound and converts the received ambient sound into analog electrical signals, and an analog-to-digital converter that converts the analog electrical signals into digital signals representative of the ambient sounds. The earpiece further includes a digital signal processor that performs a transformation operation on the digital signals according to instructions received from a mobile device, the transformation operation transforms the digital signals into modified digital signals, a digital-to-analog converter that converts the modified digital signals into modified analog electrical signals, and a speaker that outputs the modified analog electrical signals as audio waves.

Abstract: An electro-acoustical transducer, including a magnetic assembly producing a magnetic field having two or more displaced regions of greater intensity, having magnetic flux in substantially similar directions, separated and surrounded by regions of lower intensity magnetic field, and an electrically conductive and mobile member disposed in and capable of moving through a magnetic field.

Abstract: A tensioning system for a cleaning blade for a conveying belt. The tensioning system has a frame, a blade support, and a ratchet system. The blade support is movable around a first axis in a first direction to increase cleaning blade pressure and a second direction oppositely to the first direction to decrease cleaning blade pressure. Through the ratchet system, a position of the blade support can be maintained against pivoting in the second direction. The ratchet system has (a) a first ratchet assembly on one of the frame and blade support with at least one ratchet surface facing in a first circumferential direction relative to the first axis and (b) a second ratchet assembly on the other of the frame and blade support and having a first plurality of ratchet surfaces facing in a second circumferential direction oppositely to the first circumferential direction.

Abstract: A conveyor system having a conveying belt trained around a plurality of guide rollers for movement in an endless travel path to convey articles and materials in a travel line. A first roller is mounted in an operative position on a support to bear against the conveying belt. A roller safety support system has a wall assembly that confines downward movement of the first roller in the event that the first roller becomes disengaged from the operative position. The roller safety support system further includes a frame assembly. The wall assembly is mounted to the frame assembly so that an upwardly facing surface on the wall assembly bears supportingly against the first roller in the event that the first roller becomes disengaged from the operative position. The upwardly facing surface bounds a receptacle in which the first roller is confined by the wall assembly in the event that the first roller disengages from the operative position. The receptacle has a variable configuration.

Abstract: A conveyor system having a conveying belt trained around guide rollers for movement in a travel path, a first roller which is mounted in an operative position on a support to bear against the conveying belt, and a roller support system. The roller support system has at least one wall which confines downward movement of the first roller in the event that the first roller becomes disengaged from its operative position. The roller support system defines at least one opening through which foreign matter separated from the first roller can pass.

Abstract: A mounting system for a cleaning blade for a conveying belt. The mounting system has a mounting assembly with a) a first connecting portion through which a cleaning blade can be joined to the mounting assembly and b) a mounting portion which can be attached to a support to maintain the mounting assembly in a desired operative position relative to a conveying belt that is to be cleaned so as to situate a cleaning belt joined to the mounting assembly in a first operative position. The mounting assembly has a second connecting portion that can be used in place of the first connecting portion and through which a cleaning blade can be joined to the mounting assembly so as to situate a cleaning blade joined to the mounting assembly in a second operative position.

Abstract: A suspension element allowing motion along an axis including two or more radial, compliant suspension arms, each having a central portion deviating circumferentially and arranged such that the midportion of each arm can translate along at least one of the circumferential or radial directions during axial translation to distribute stress along and across the path. The suspension element is adapted for use in an electro-acoustical device.

Abstract: A load bearing assembly for a conveying belt. The load bearing assembly has a main body for attachment to a support, and a support layer capable of being operably attached to the main body and having an exposed bearing surface to act supportingly against a conveying belt. The main body has a first shoulder facing a first direction, with the support layer having a second shoulder facing oppositely to the first direction and confronting the first shoulder to prevent separation of the main body and support layer with the support layer operably attached to the main body.

Abstract: A wiper blade for endless conveyor belts has three basic components or features which improves blade performance over the prior art. These components include:1. a multiradius side profile having a concavity defining the torsion resistance point,2. a thicker base section, and3. a high profile metal mounting insert.These three components act together to substantially reduce the bending moments associated with wiper blade operation and provide an improved structural profile with a high moment of inertia and shorter effective column length. These structural improvements allow the use of softer and more wear-resistant elastic polymers without the risk of blade buckling. The multiradius concave side profiles allow the use of a short thin blade tip profile which transitions to the thicker, ridged base profile. The bending moment generated by the operational forces is now resisted primarily at the transition point of the two profiles, e.g.

Abstract: A slurry pump suction side liner with replaceable components is provided utilizing separate suction port assembly, wear ring assembly, wear plate assembly and backing plate assembly components connected together to form a rigid suction side liner for directing a slurry into an impeller inlet. A replaceable annular wear ring having a first wear resistant surface facing the inlet axis and a second wear resistant surface at right angles to the inlet axis is provided to maintain a predetermined gap between gap between the impeller and replaceable wear ring to prevent slurry flow between the impeller and suction side liner assembly. An annular wear plate assembly having a wear resistant surface flush with the second wear resistant surface on the wear ring assembly is also provided to extend the gap radially outward from the wear ring, which is positioned between a suction port and the impeller.
