Patents by Inventor Mathias Jotter

Mathias Jotter 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: 10734148
    Abstract: An electromagnetic holding magnet and a method for manufacturing the same, and an electromagnetic locking element that, that in a preferred embodiment, is a lock in a container of an oxygen emergency supply system of an aircraft. The electromagnetic holding magnet includes a yoke and a retaining plate interacting with the yoke as an anchor. At least one permanent magnet generates a magnetic retaining flux in the yoke that includes a first yoke leg and a second yoke leg as well as a middle pole. The middle pole is surrounded in sections by a magnetic coil. The first and second yoke legs are arranged symmetrically in relation to the middle pole and the magnetic coil.

  • Patent number: 8672963
    Abstract: The present invention relates to a lancet device, by which a lancet can be displaced along a piercing path for generating a piercing wound in a skin surface, in particular to obtain bodily fluid for diagnostic purposes, comprising a lancet drive having drive means to generate a drive force for a piercing movement of the lancet along the piercing path in the direction toward the skin surface. According to the present invention, the lancet drive comprises a magnet, by which a magnetic retention force oriented opposite to the drive force may be generated, and the lancet drive also comprises triggering means, by which the retention force may be reduced enough that the lancet is accelerated in the direction toward the skin surface under the effect of the drive force generated by the drive means.

  • Patent number: 7847661
    Abstract: An actuation magnet is provided for moving a closure needle of a hot-runner nozzle of an injection molding tool. The actuation magnet has an armature which is coupled in movement to the closure needle and may be displaced between first and second cores by subjecting at least one coil to current. A permanent magnet is arranged in a manner such that it exerts an additional magnetic force on the armature in at least one, preferably two, movement directions.
