System and method for routing input signals using single pole single throw and single pole double throw latching micro-magnetic switches
First Claim
1. A system comprising:
- an input section that receives input signals;
an output section that transmits output signals based on the input signals; and
a switching section that includes switches that control transmission of the input signals from the input section to the output section, the switches including, a magnet proximate to a substrate, a cantilever coupled to the substrate and positioned proximate to the magnet, the cantilever coupled to a magnetic material, and a conductor coupled to the substrate, the conductor conducting a current that induces a first torque in the cantilever.

Abstract
A system and method are used to route input signals from an input node to N output nodes. The system includes an input section that receives input signals, an output section that transmits output signals based on the input signals, and a switching section. The switching section includes switches that control transmission of the input signals from the input section to the output section. The switches can be latching micro-magnetic switches that include a magnet proximate to a substrate, a cantilever coupled to the substrate and positioned proximate to the magnet, the cantilever coupled to a magnetic material, and a conductor coupled to the substrate, the conductor conducting a current that induces a first torque in the cantilever.

12. A method comprising:
-
receiving an input signal; and
routing the input signal to output sections using latching micromagnetic switches having a cantilever that moves between a first state and a second state based on a first torque generated by a first magnetic field produced by a magnet and a second torque generated by a second magnetic field produced by current flowing through a conductor. - View Dependent Claims (13, 14, 15, 16, 17)

switching means for providing a second magnetic field;
means on the cantilever for causing the cantilever, while in a presence of the first magnetic field, to be in one of a normally on or normally off state; and
control means for activating the switching means to switch the state of the cantilever.
