George F. Cardas 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: 6004166
    Abstract: An electrical connector has separable members for clamping plural conduits for separable circuits for electronic equipment. The members are clamped by a securement member extending through passages in the members and secured by a fastener. A plurality of prongs extend through openings in the members to engage electrical conductors to external circuits.
    Type: Grant
    Filed: September 29, 1997
    Date of Patent: December 21, 1999
    Inventor: George F. Cardas
  • Patent number: 5335282
    Abstract: A microphone comprises a plurality of oppositely oriented electroacoustic transducer pairs arranged in a body or a resonator cavity and electrically algebraically summed, whereby ambient acoustic shock impulses and vibration induce opposite electrical phase output, while an audio signal entering an acoustic channel to the transducer cavity produces a damped, in-phase, summed output, greatly enhancing the signal to noise ratio and producing a high output level that is substantially non-microphonic.

  • Patent number: 4980517
    Abstract: A multi-strand electrical cable having electrically conductive strands of different cross-sections, i.e. cross-sectional areas, arranged in ascending order of strand cross-section from the center toward the outer circumference of the cable and sized in accordance with an irrational and preferably golden ratio progression in such a way that larger strands are located outwardly toward the cable circumference relative to smaller strans and stabilize the smaller strands against resonant vibration in a manner such as to reduce cable resonance produced by fluctuating current flow through the cable.

  • Patent number: 4628151
    Abstract: Optimum signal/power transmission characteristics are realized in a cable containing a plurality of individually insulated conductors which vary in size one to another wherein the ratio of the size of one conductor to the next larger conductor is about 0.62. Normally, at least three different sizes of conductors will be employed in a cable wherein each size classification differs from the next larger or smaller size classification by the specified ratio. This particular ratio is often called the golden section and is the ratio between the two sizes in which the lesser of the two is to the greater as the greater is to the sum of both.
