Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
199 words
A magnetically controlled switching matrix, comprising: a plurality of magnetic members arranged in rows and columns of said switching matrix, each member made from a magnetic material having at least two stable states of magnetization; a first coil of each of said magnetic members placed thereon which induces a magnetic flux in said member and is connected into the electric circuit of said matrix row associated with said magnetic member; a second coil of each of said magnetic members placed thereon which induces a magnetic flux in said member and is connected into the electric circuit of said matrix column associated with said magnetic member; each said magnetic member magnetically coupled with at least one respective magnetically responsive switch; a row selection circuit having an input and an output electrically connected with all of said first coils of said magnetic members; a column selection circuit having an input and output electrically connected with all of said second coils of said magnetic members; a generator of decaying alternating current pulses with its output connected with the input of said row selection circuit; and a direct current generator with the output thereof connected with the input of said column selection circuit.
Claim 2
Dependent Claim
199 words
A magnetically controlled switching matrix, comprising: a plurality of magnetic members arranged in rows and columns of said switching matrix, each member made from a magnetic material having at least two stable states of magnetization; a first coil of each of said magnetic members placed thereon which induces a magnetic flux in said member and is connected into the electric circuit of said matrix row associated with said magnetic member; a second coil of each of said magnetic members placed thereon which induces a magnetic flux in said member and is connected into the electric circuit of said matrix column associated with said magnetic member; each said magnetic member magnetically coupled with at least one respective magnetically responsive switch; a row selection circuit having an input and an output electrically connected with all of said first coils of said magnetic members; a column selection circuit having an input and output electrically connected with all of said second coils of said magnetic members; a generator of decaying alternating current pulses with its output connected with the input of said row selection circuit; and a direct current generator with the output thereof connected with the input of said column selection circuit.
Claim 3
Dependent Claim
31 words
A switching matrix as defined in claim 1, in which said first and said second coils are wound on said magnetic member so that the magnetic fluxes induced thereby are coaxial.
Claim 4
Dependent Claim
31 words
A switching matrix as defined in claim 1, in which said first and said second coils are wound on said magnetic member so that the magnetic fluxes induced thereby are orthogonal.
Claim 5
Dependent Claim
44 words
A switching matrix as defined in claim 2, which further contains closed loops placed on said magnetically responsive switches and made from a non-magnetic material exhibiting electric conductance sufficient to protect said magnetically responsive switches from the effect of a decaying alternating magnetic field.
Claim 6
Dependent Claim
31 words
A switching matrix as defined in claim 4, which, in the event each magnetic member is magnetically coupled with one magnetically responsive switch, includes a closed loop placed on this switch.

Claim 8
Dependent Claim
33 words
A switching matrix as defined in claim 1, in which the magnetically responsive switches are disposed so that the magnetic axes of all the magnetically responsive switches run parallel with the matrix columns.
