    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 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: In an embodiment of the present invention there is provided a micro-electromechanical (MEMS) accelerometer, including a substrate, a first sensor and a second sensor. The first sensor is configured to measure an acceleration along a first axis parallel to a plane of the substrate. The second sensor is configured to measure an acceleration along an axis perpendicular to the plane of the substrate. The second sensor comprises a first beam, a second beam and a single support structure. The single support structure supports the first and second beams relative to the substrate, wherein the first and second beams circumscribe the first sensor.
