Karl Reinitz 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: 7316694
    Abstract: A surgical suturing device has a body with a ā€œJā€-shaped suturing needle attached. One end of a movable arm is pivotably attached to the body so that the other end of the movable arm may swing into and out of engagement with the tip of the suturing needle. The movable arm is engaged by a rod that slides transversely within the body. The moveable arm swings in response to pressure on a thumb nut that moves the rod. Rod movement is resisted by a compression spring within the body. The device allows a surgeon to suture the fascial layer from within a surgical incision. The surgeon avoids unwanted penetration of tissue by pressing the thumb nut to cause the movable arm to engage and cover at least a portion of the needle tip.

  • Patent number: 5707879
    Abstract: A neutron radiation detector is described. A semiconductor material is populated with helium three (.sup.3 He) atoms to increase its overall neutron capture efficiency. Upon capture of a neutron by a .sup.3 He atom, a tritium ion and a proton are generated with energies of 0.191 and 0.573 MeV, respectively. These energies are deposited in the semiconductor material creating electron-hole pairs. The electron-hole pairs are withdrawn from the material by the application of an electric field and are collected as charges at the terminals. The associated circuitry processes the charges into pulses with these being counted and their sizes measured. The results are recorded and displayed. The number of pulses are a measure of the number of neutrons absorbed in the detector and of the neutron flux of interest. In many instances the detector can also be used to detect and display non-neutron type radiation or simultaneously neutron and non-neutron forms of radiative activity.

  • Patent number: 4517515
    Abstract: A magnetic-field detection device useful as a sensitive magnetometer. The device employs a solid-state field-sensing element which experiences a change in permeability when it is exposed to a magnetic field. The change in permeability results in a change in skin depth and therefore in resistance offered by the element to passage of a high-frequency alternating current. The element is used as one arm of a balanced bridge circuit to which an A.C. voltage is applied. Upon exposure to a magnetic field, the bridge is rebalanced to a null, the amount of current flow or rebalancing being measures of the magnetic field strength.
