Abstract: Systems and methods for reducing vibrations perceived by a human due to an artificial heart valve include a vest that is wearable around a torso of the human, a plurality of sensors mounted to the vest, a plurality of vibration-generating actuators mounted to the vest, and a controller. The plurality of sensors detects vibrations in the human generated by the artificial heart valve. The controller is operable to receive signals representing the detected vibrations from the plurality of sensors, and is operable to produce anti-vibration signals that substantially attenuate the detected vibrations. A first sensor of the plurality of sensors is located near a first vibration-generating actuator of the plurality of vibration-generating actuators to form a sensor/actuator set. In the sensor/actuator set, the anti-vibration signals generated by the controller for the first vibration-generating actuator correspond to the vibrations detected by the first sensor.

Abstract: Cable assemblies include at least a first wire and a second wire. The wires are enclosed, using injection molding, by a respective layer of thermo-resistant material. During the injection molding, the first wire and second wire are kept substantially straight so as to avoid kinks in at least one of the first wire and the second wire that can develop subsequent to the molding if a wire is not substantially straight. The tension associated with the first wire and the second wire is kept within a predetermined range or below a predetermined threshold. The predetermined range/threshold depends on a temperature associated with the injection molding. The injection molding can provide a zip structure over the wires such that the zip structure can be zipped-together and zipped-apart to prevent entanglement of the wires when used by a user.

Abstract: A zipper assembly is described that includes a first set of electrical wires, a second set of electrical wires, and a first set of zipper teeth. The first set of electrical wires can be encapsulated by a first inner layer made of a thermo-resistant material. The second set of electrical wires can be encapsulated by a second inner layer made of the thermo-resistant material. The first set of zipper teeth can be connected to a zipper tape fabric that is woven with the first inner layer and the second inner layer. The first set of zipper teeth can be configured to be attached to an article of clothing. The first set of zipper teeth can be releasably attached to a second set of zipper teeth attached to the article of clothing. Related methods, systems, apparatuses, and products are also described.

Abstract: Preferred assemblies are directed to a cable assembly that includes a first electrical wire and a second electrical wire; with a thermo-resistant material that is molded around the wires. Zipper teeth are molded to the thermo-resistant material of both of the wires. The zipper teeth on the first wire are releasably attached to the zipper teeth on the second wire, and at least one reinforcing fiber is encapsulated with one of the wires.

Abstract: A flat panel sound radiator having improved audio performance is provided. The sound radiator has a panel to which is coupled a traditional electromechanical exciter for imparting audio frequency vibrational energy to the panel. The panel has a honeycomb core made of Kraft paper, which is flexible, has a low self noise, and high noise damping characteristics. The core is sandwiched between facing skins made of a material with a high Young's modulus, a high tan delta, a high tensile strength, and low self noise. Preferably, this material is an aramid polyamide such as Kevlar®, Nomex®, Conex®, or Technora®, all of which exhibit these properties. The facing skins are fixed to the core with an adhesive that is flexible and has high acoustic damping qualities and high shock resistance, such as rubber cements, silicone adhesives, and water-based acrylic adhesives.

Abstract: An improved flat panel sound radiator assembly is provided for reproducing high quality sound at volume levels substantially higher than existing flat panel sound radiator systems. The assembly includes a flat panel radiator having a core sandwiched between facing skins. The core, which preferably is a honeycomb core, and the skins are made of materials that result in a substantially enhanced signal-to-noise ratio and enhanced bass response when reproducing sound. The flat panel radiator is disposed within a frame and the peripheral edges of the radiator are movably coupled to the frame with a compliant surround. An exciter, which may be a traditional magnet structure, is mounted on and supported by a bridge structure spaced from the inside face of the radiator and is coupled to the radiator only through a voice coil assembly. In use, the radiator produces sound through distributed mode reproduction below a sound level threshold.

Abstract: A loudspeaker system for use as a subwoofer or other bass speaker system utilizes an enclosure with at least one speaker mounted therein and a port to form a bass reflex system. The bass reflex system is tuned to a selected low frequency range so that the acoustical output within such low range of the frequency spectrum of the loudspeaker system is enhanced while minimizing speaker cone excursion and distortion. Whereas the bass reflex speaker system loads the speaker at the selected low frequency range, a waveguide in the form of a quarterwave resonator is included in the loudspeaker system for loading the speaker at a higher frequency range which is still within the frequency range of the speaker system, so that acoustical output is enhanced and speaker cone excursion and distortion are minimized at the upper end of the frequency range. The resonator is designed to function as a quarterwave resonator within the upper frequency range.

Abstract: A time compression audio reproduction system has two stereo channels with means for synchronously operating the pitch correction means in each channel to obtain time coincidence between corresponding portions of the signal output from each channel. Features include switching for alternately selecting delay elements.

Abstract: A time compression/expansion system for recorded programs provides time change on playback with pitch correction free of gaps or processing noise due to splicing and discard. A dual memory delay system operated to inversely vary delay is used to provide an interval during which to detect the start of the next program sample with matched signal amplitude and sign. During this interval pitch correction is a continuous extension of the current sample. The system can include individual processing of contiguous frequency bands.

Abstract: A time compression/expansion audio reproduction system of the type that provides pitch correction by repetitive variable time delay achieves improved performance by separating the reproduced signal from a recording into components which are separately delayed. For studio quality reproduction the signal is separated into contiguous frequency bands which are each delayed synchronously and the processing noise in each band is eliminated by filtering each band signal after delay to eliminate high frequency components. Bandpass filtering prior to recombination as well as blanking and amplitude compression and expansion are also disclosed.
