Patents by Inventor William Buchele

William Buchele 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).

  • Publication number: 20060038635
    Abstract: A method for implementing an inductor-capacitor filter in an integrated circuit. Embodiments of the invention implement a 5-pole LC low-pass filter suitable for incorporation in wireless applications necessitating compact layouts. Inductors are formed in an IC as concentric coils on metallization layers, the concentric coils providing a negative coupling coefficient between the inductors. The invention provides programmable frequency response characteristics, enabling the transmission of high-frequency base band information while attenuating carrier RF frequencies.

  • Patent number: 5276910
    Abstract: The present invention comprises a hearing system apparatus and method for electromagnetically communicating signals to a magnetic transducer. The apparatus includes a signalling circuit for producing a pulse-width modulated current signal. An antenna means is coupled to the signalling circuit for producing a variable electromagnetic field whose energy intensity is modulated by the output of the signalling circuit. In addition, an energy storage circuit is coupled to the antenna for storing a substantial portion of the energy stored in the magnetic field produced by the antenna when the magnetic field collapses between cycles of the current signal. Also, an energy recycling circuit is coupled to the storage circuit and the antenna for recovering the energy stored in the storage circuit for use in the next electromagnetic field cycle.
