  • Patent number: 9336953
    Abstract: The present invention generally relates to methods for increasing the lifetime of MEMS devices by reducing the number of movements of a switching element in the MEMS device. Rather than returning to a ground state between cycles, the switching element can remain in the same state if both cycles necessitate the same capacitance. For example, if in both a first and second cycle, the switching element of the MEMS device is in a state of high capacitance the switching element can remain in place between the first and second cycle rather than move to the ground state. Even if the polarity of the capacitance is different in successive cycles, the switching element can remain in place and the polarity can be switched. Because the switching element remains in place between cycles, the switching element, while having the same finite number of movements, should have a longer lifetime.

  • Patent number: 9330872
    Abstract: An electromagnetic relay includes a contact that includes a fixed contact and a movable contact, a permanent magnet provided on the peripheral side of the contact, and a non-magnetic body. The movable contact is displaceable in a first direction to move toward the fixed contact and in a second direction to move away from the fixed contact. The permanent magnet has a polarity direction perpendicular to the first and second directions. The non-magnetic body faces toward the direction of a Lorentz force that acts based on the permanent magnet in a direct electric current flowing through the contact.
