    Abstract: A method of manufacturing an insulating micro-structure (100) by etching a plurality of trenches in a silicon substrate (101) and filling said trenches with insulating materials (105, 107). The trenches are etched and then oxidized until completely or almost completely filled with silicon dioxide. Additional insulating material is then deposited as necessary to fill any remaining trenches, thus forming the structure. When the top of the structure is metallized, the insulating structure increases voltage resistance and reduces the capacitive coupling between the metal (109) and the silicon substrate. Part of the silicon substrate underlying the structure is optionally removed further to reduce the capacitive coupling effect. Hybrid silicon-insulator structures can be formed to gain the effect of the benefits of the structure in three-dimensional configurations, and to permit metallization of more than one side of the structure.

    Abstract: A system (10) and method detect freefall associated with an object that is spinning or tumbling as it falls. Two tri-axis accelerometers (14, 16) provide inputs to an algorithm (28) that detects the freefall of a spinning object that would not otherwise be detected by a conventional freefall detection system, due to the centrifugal and centripetal forces being placed on the falling object as it spins. The system can be used to detect the freefall of portable devices with onboard memory or hard disk drives, allowing the devices to have time to park the read/write head and reduce the potential of losing data that can be damaged by impact. This freefall detection system may be applied to such portable devices as notebook computers, PDAs, MP3 players, digital cameras, mobile phones and even automobiles.

    Abstract: A relay (10) for switching an electrical signal includes switching elements(14, 18), an actuator (12) for closing the switch (18), and an actuator for opening the switch (12), the latter two of which are mechanically decoupled when the relay (10) is in a mechanical rest position. When a relay close signal is applied, the closing actuator (18) electrostatically drives the switching elements (14, 18) to complete a signal path between two terminals for the switched signal (22,24). In the process of closing the switch, the opening actuator (12) remains stationary, i.e., no mass is displaced. Application of a switch open signal electrostatically drives the opening actuator, optionally in combination with a mechanical restoring force on the closing actuator (18) to open the switch (18) to break the signal conduction path for the switched signal.

    Abstract: An accelerometer. A silicon wafer is etched to form a fixed portion, a movable portion, and a resilient coupling between, the fixed and movable portions generally arranged in the plane of the wafer, the mass of the movable portion being concentrated on one side of the resilient coupling. One of the fixed and moveable portions of the silicon structure includes a first electrode. The other of the fixed and moveable portions includes a second electrode oriented parallel to the axis of acceleration, and an electrically-conductive layer electrically connected as a third electrode coplanar and mechanically coupled with the second electrode. The second and third electrodes are arranged in capacitive opposition to the first electrode, the capacitance between the first electrode and third electrode increasing as the movable portion moves in a direction along the axis of acceleration relative to the fixed portion and decreasing as the movable portion moves in an opposite direction. A resilient coupling retains the first and third electrodes in capacitive opposition to each other across a capacitance gap while allowing motion of the first electrode relative to the second and third electrodes in response to acceleration along an axis of acceleration perpendicular to the plane of the wafer, and resiliently restores the first electrode to an equilibrium position when the acceleration ceases. The second electrode is in opposition to a majority of the surface area of the first electrode when the electrodes are in the equilibrium position. Capacitance between the first and third electrodes is measured to obtain a measurement of acceleration along the axis.
