Rotation of an inertial mass included in the gyro is produced by applying a torque to the inertial mass about a rate axis orthogonal to the drive axis along or about which the drive motion of the inertial mass is defined. The torque is applied by created a potential difference between interdigitated finger electrodes, by a piezoelectric element or any other known or later discovered means. The combination of the drive motion and the torque produces a Coriolis force which produces a displacement of a sense element coupled to the inertial mass or a displacement of the inertial mass itself. The induced rotation about the rate axis simulates the angular momentum which would be produced in the gyro by a precision rate table. This displacement or response is then an empirical parameter which characterizes the gyro's response to a simulated rate table test and can then be used to generate a correction factor for the gyro and to thus calibrate it.

A self-regulating tire pressure system and method employs a bistable valve (10) that allows air from a high pressure reservoir (6) to replenish the pressure within a tire (4) when it has fallen below an actuating pressure, and discontinues its operation only after the tire pressure has increased to a closing pressure that is greater than the actuating pressure. The system is capable of sensing the valve's (10) frequency of operation as an indication of a slow tire leak when the frequency exceeds a predetermined threshold, of sensing the number of valve (10) operations and the duration of each operation as an indication of a flat tire condition when the number of operations for a predetermined duration exceeds a second threshold, and of sensing the duration of the valve's (10) operation as an indication of a low reservoir (6) pressure condition when that duration exceeds a third threshold. The valve (10) includes a bistable diaphragm (94, 120) that receives a reference pressure on one side and the tire pressure on its opposite side, and snaps between two stable positions respectively opening and closing the valve (10) in response to the tire pressure falling below the actuating pressure and then increasing to the closing pressure.

A micro-gyro device is disclosed combining an element which oscillates around the drive axis and an element which rocks around the output axis, so arranged that Coriolis force is transmitted from one element of the other without any substantial transfer of motion of either element to the other in its own direction of motion. In other words, the masses of the two elements operate independently of one another, providing improved performance, and individual adjustability to compensate for any manufacturing imprecision. The presently-preferred device combines an outer ring which oscillates around the drive axis with an inner disk which rocks around the output axis, whenever external rotating motion occurs about the rate axis.

A secondary ion mass spectrometry system and method is described which operates several orders of magnitude more quickly than previous systems, and captures information that might previously have been missed. A parallel detection approach is used which simultaneously monitors all secondary ion masses of interest, as opposed to prior serial approaches which sense only one ion mass at a time. The secondary ions are spatially separated according to mass and sensed by a detector array. An ion-electron converter and amplifier, implemented as a microchannel plate assembly, is preferably interfaced between the mass separator and detector. The detector preferably uses an array of wires to collect charge emitted by the microchannel plate. The wires are coupled to output lines by an encoding scheme which allows many fewer output lines to be employed than there are wires.

A tire air pressure sensor is mounted on a vehicle wheel and includes an inertial mass which is urged radially outwardly by centrifugal force resulting from rotation of the wheel. The tire air pressure is applied to the inertial mass in opposition to the centrifugal force. When the rotational speed of the wheel is sufficient that the centrifugal force overcomes the applied air pressure, the inertial mass moves radially outwardly and opens a switch. The speed at which the switch opens is a predetermined function of the tire pressure. In another embodiment, a second sensor is provided to sense when the tire pressure is below a minimum value. A spring urges an inertial mass inwardly in opposition to the centrifugal force, and the tire pressure is applied to a bellows having an end which moves radially outwardly in proportion to the applied pressure. The bellows opens a first switch when the pressure is higher than the minimum value, and the inertial mass moves radially outwardly away from the end of the bellows to open a second switch when the wheel speed exceeds the value corresponding to the tire pressure.
