Joachim Folsch 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).

  • Multicolor-color sensor
    Patent number: 6281561
    Abstract: A multicolor sensor with a plurality of diode functions comprising a succession of layers with p and n doped layers. A microcrystalline layer is thus constructed from at least one of the internal contacts for contacting. According to the invention, pin, nip, npin and/or pnip structures are provided to form the diode functions.

  • Three-color sensor with a pin or nip series of layers
    Patent number: 5998806
    Abstract: A pin or nip layer sequence, especially for use as a color sensor in electrooptical components. The bond gap of a first intrinsic (i) layer closer to the light input side is greater than the bond gap of a second i layer adjacent to the first and further removed from the light input side. The new .mu..tau. product for the i layer furthest distant from the layer is greater than the .mu..tau. product of an i layer closer is the n layer.
