摘要： A directional tap detection algorithm and a single tri-axis accelerometer are employed to extend the number of unique button less input commands available for a small mobile electronic device. The algorithm analyzes acceleration data from the tri-axis accelerometer to detect the direction and number of taps imparted to any of the six sides of a housing of the device, yielding 12 unique inputs. The algorithm employs a parameter referred to as the performance index (PI) to identify tap induced movements. The PI is determined by calculating the time derivative of each acceleration signal for each axis and then calculating the sum of the absolute values of the calculated acceleration derivatives. A tap is determined to have occurred if the sum exceeds a threshold value for a predetermined amount of time. If a second tap is detected within a predetermined time after the first tap, then a double tap is determined to have occurred.

摘要： A method for making a polymeric microfluidic structure in which two or more components (layers) of the microfluidic structure are fixedly bonded or laminated with a weak solvent bonding agent, particularly acetonitrile or a mixture of acetonitrile and alcohol. In an aspect, acetonitrile can be used as a weak solvent bonding agent to enclose a microstructure fabricated in or on a non-elastomeric polymer such as polystyrene, polycarbonate, acrylic or other linear polymer to form a three-dimensional microfluidic network. The method involves the steps of wetting at least one of the opposing surfaces of the polymeric substrate components with the weak solvent bonding agent in a given, lower temperature range, adjacently contacting the opposing surfaces, and thermally activating the bonding agent at a higher temperature than the lower temperature range for a given period of time. The contacted polymeric substrates may also be aligned prior to thermal activation and compressed during thermal activation. A laminated, polymeric microfluidic structure is also disclosed.

摘要： Deep reactive ion etching creates a single mask MEMS structure 20-50 micrometer deep on the top surface of the wafer. Thereafter, a bottom surface etch cooperates with trenches formed in the MEMS structure to provide through trenches which release large area structures (86) of arbitrary shape and having a thickness up to that of the wafer. The releases structure is supported in the wafer by MEMS support beams (102, 104) and motion is detected and affected by MEMS sensors and actuators, respectively.

摘要： An oscillatory gyroscope is described with decoupled drive and sense oscillators and reduced cross-axis sensitivity. The gyroscope is fabricated using a plasma micromachining process on standard silicon wafers. The electrical isolation of the drive and sense functions of the gyroscope, contained within the same micromechanical element, reduce cross-coupling while obtaining high inertial mass and high sensitivity.

摘要： 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.

摘要： 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.
