Thorvald Larsen has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11367420
    Abstract: The invention relates to a string (1) for a stringed, bowed musical instrument, for example a bowed musical instrument like violin, viola or cello. The string has a first, load bearing core (10) and a winding strand (100) wound around the first core in helical windings. A damping agent (40) suitable for vibration damping is arranged in a profiled recess (150) in the winding strand. The recess is functioning as a reservoir between the first core and the winding strand. The reservoir is containing and/or retaining the damping agent so as to, at least, reduce dissipation of the damping agent through a gap between the adjacent helical windings of the winding strand. The invention results in a longer lifetime with optimum acoustic properties of the string.

  • Publication number: 20210214891
    Abstract: Method for fabricating a string, in particular a string for a bowed musical instrument, said string having a core with at least one winding strand helically wound thereon, thereby forming a string with at least one core and at least one winding layer, the method comprising: placing a core axially along a path, spinning the core about its central axis and helically winding at least one winding strand around the string, preferably without overlaps between adjacent windings and/or large gaps between adjacent windings, of more than about 12% of the width of the individual winding strand, between adjacent windings, wherein for increasing compactness of the string a friction force is applied to the at least one winding strand by a compactness increasing module at a spinning point, said spinning point being defined as the point where the at least one winding strand is being wound on to the string, consisting of at least one core, and a compression force is applied to the at least one winding strand and the string by

  • Patent number: 10903411
    Abstract: The present disclosure relates to semiconductor based Josephson junctions and their applications within the field of quantum computing, in particular a tuneable Josephson junction device has been used to construct a gateable transmon qubit. One embodiment relates to a Josephson junction comprising an elongated hybrid nanostructure comprising superconductor and semiconductor materials and a weak link, wherein the weak link is formed by a semiconductor segment of the elongated hybrid nanostructure wherein the superconductor material has been removed to provide a semiconductor weak link.

  • Patent number: 5685489
    Abstract: A shower head includes a mouthpiece having a central, axial, throughgoing channel for flow-through of water. A rotationally symmetrical deflector element for the water is situated in the vicinity of the outer mouth of the channel. The mouthpiece is in threaded connection with a support through which the water is supplied and is adapted to be adjusted axially relatively to the support. The deflector element is carried by a stem which extends axially in the channel with a radial clearance and is fastened to the support. On the side facing the channel, the deflector element is concave, in that a circumferential groove having a curved cross section extends around the stem. The region of the mouthpiece around the deflector element provides a conical surface which extends converging outwardly. The shower head reduced water consumption at low water pressure and also permits pulsating showering.
