  • Publication number: 20030222740
    Abstract: A micro-magnetic switch includes a permanent magnet and a supporting device having contacts coupled thereto and an embedded coil. The supporting device can be positioned proximate to the magnet. The switch also includes a cantilever coupled at a central point to the supporting device. The cantilever has a conducting material coupled proximate an end and on a side of the cantilever facing the supporting device and having a soft magnetic material coupled thereto. During thermal cycling the cantilever can freely expand based on being coupled at a central point to the supporting device, which substantially reduces coefficient of thermal expansion differences between the cantilever and the supporting device.

  • Publication number: 20030179058
    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.

  • Publication number: 20030173957
    Abstract: A system that senses proximity includes a magnet producing a magnetic field and a sensor having a switch. The switch includes a cantilever supported by a supporting structure. The cantilever has a magnetic material and a longitudinal axis. The magnetic material makes the cantilever sensitive to the magnetic field, such that the cantilever is configured to move between first and second states. The switch also includes contacts supported by the support structure. The switch can be configured as a reed switch. When the magnet moves relative to the sensor, the cantilever interacts with a respective one of the contacts based on the position of the magnet during movement.

  • Publication number: 20030025580
    Abstract: An apparatus includes an electrical device and a latching micromagnetic switch that controls energy flow through the electrical device. The latching micromagnetic switch includes a cantilever, a permanent magnet, and a coil configured to latch the latching micromagnetic switch in one of two positions each time energy passes through the coil. The electrical device and the latching micromagnetic switch can be integrated on a same substrate. Otherwise, the electrical device and the latching micromagnetic switch can be located on separate substrates and coupled together. The electrical device can be a circuit, a filter, an antenna, a transceiver, or the like.

    Abstract: An apparatus includes an circuit and a latching micromagnetic switch that controls energy flow through the circuit. The latching micromagnetic switch includes a cantilever, a permanent magnet, and a coil configured to latch the latching micromagnetic switch in one of two positions each time energy passes through the coil. The electrical device and the latching micromagnetic switch can be integrated on a same substrate. Otherwise, the electrical device and the latching micromagnetic switch can be located on separate substrates and coupled together. The circuit can be a transistor or an array of transistors connected in parallel. If the circuit is an array of transistors, there can be an array of the switches, where each one of the switches is coupled to a corresponding one of the transistors. The switches are coupled to at least one of a source, drain, or gate of the corresponding transistor.
