摘要： 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. The sensor can have multiple functionalities, such as it can: (1) be used to detect distance to an object, (2) be used to detect direction of a moving object, (3) include a memory that stores a last location of an object; (4) detect ferromagnetic-based materials and hard or soft magnetic objects; (5) be used to detect velocity and/or acceleration of an object and/or (6) be modified to include any function desired by a user.

摘要： A new optical switch device and method of operating such a device overcomes alignment problems through the use of an optical signal-confining channel that may be embedded so as to confine optical signals in a desired propagation path such that the optical signal's alignment with the output is secured. Small-angle mirrors may be used so as to direct the optical signal into the intended optical signal-confining channels so as to achieve the desired optical switching. The mirrors could be latching micro-mirrors or non-latching micro-mirrors. Such mirrors could be controlled by electrostatic actuation, thermal actuation or electromagnetic actuation, or any other technique.

摘要： A micro magnetic latching device. The device comprises a substrate having a moveable element supported thereon. The moveable element (cantilever) has a long axis and a magnetic material. The device also has first and second magnets that produce a first magnetic field, which induces a magnetization in the magnetic material. The magnetization is characterized by a magnetization vector pointing in a direction along the long axis of the moveable element, wherein the first magnetic field is approximately perpendicular to a major central portion of the long axis. The device also has a coil that produces a second magnetic field to switch the movable element between two stable states, wherein only temporary application of the second magnetic field is required to change direction of the magnetization vector thereby causing the movable element to switch between the two stable states.

摘要： A method and apparatus for controlling the coupling of a circuit into a signal path is described. A moveable element is supported by a substrate and has a magnetic material and a long axis. At least one magnet produces a first magnetic field. The first magnetic field induces a magnetization in the magnetic material. The magnetization is characterized by a magnetization vector pointing in a direction along the long axis of the moveable element. The first magnetic field is approximately perpendicular to a major central portion of the long axis. A coil produces a second magnetic field to switch the moveable element between first and second stable states. Only temporary application of the second magnetic field is required to change direction of the magnetization vector, which causes the moveable element to switch between the first and second stable states. In the first stable state, the moveable element does not couple the circuit in series with a signal. In the second stable state, the moveable element couples the circuit in series with the signal.

摘要： A latching micro magnetic switch includes a magnet located proximate to a supporting structure. The magnet produces a first magnetic field with field lines symmetrically spaced about a central axis or non-uniform field lines. The switch also includes a cantilever supported by the supporting structure. The cantilever has a magnetic material and a longitudinal axis. The magnetic material makes the cantilever sensitive to the first magnetic field, such that the cantilever is configured to move between first and second states. The switch further includes a conductor located proximate to the supporting structure and the cantilever. The conductor is configured to conduct a current. The current produces a second magnetic field, which causes the cantilever to switch between the first and second states.

摘要： Described is a process to pattern adhesion and top contact layers in such a way that at least some portion of the top contact layers overlaps the adhesion layer, while another portion of the top contact layer overlaps with the bottom contacts, but does not overlap with the adhesion layer. The overlap between the top contact layer and the adhesion layer helps to hold the top contact layer onto the sacrificial layer. Because there is no overlap between the adhesion layer and the bottom contact, the removal of adhesion layer is no longer necessary, leading to better contacts and simplifying the fabrication process.

摘要： A method of forming a hermetically sealed MEMS package includes a step of providing a supporting GaAs substrate with at least one contact for the MEMS device on the surface of the supporting substrate and forming a cantilever on the surface of the supporting substrate positioned to come into electrical engagement with the contact in one orientation. A metal seal ring is fixed to the surface of the supporting substrate circumferentially around the contact and the cantilever. A cavity is etched in a silicon chip to form a cap member. A metal seal ring is fixed to the cap member around the cavity. The package is hermetically sealed by reflowing a solder alloy, positioned between the two seal rings, in an inert environment without the use of flux.
