摘要： Apparatuses and methods for monitoring microfeature workpiece rotation during processing, such as brushing, by monitoring characteristics corresponding to a state of a magnetic field proximate to the rotating microfeature workpiece are disclosed herein. The characteristic can depend on the relative motion between the magnetic field and the conductive material of the microfeature workpiece. The characteristic can include the strength of the magnetic field, current in an electromagnet circuit used to create the magnetic field, force exerted on the magnetic field source, or movement of the magnetic field source. The apparatus can include a feedback control device to adjust the rotation speed of the microfeature workpiece based on the characteristic detected.

摘要： A gyroscope (10) for determining rate of rotation includes a giant magnetoresistor (GMR) (14) attached to a mass (12) oscillating along a first axis. When the gyroscope (10) is rotated, the mass (12) also oscillates along a second axis perpendicular to the first axis. A magnetic element (16), which includes of a strip of magnetic bits (18), is disposed along the first axis, the second axis, or both. The magnetic bits (18) supply discrete magnetic fields. The GMR (14) changes in electrical resistance when exposed to these magnetic fields. A voltage sensor (20) and processor (34) are then utilized to calculate the rate of rotation.

摘要： A new class of sensor devices comprising field-structured conducting composites comprising a textured distribution of conducting magnetic particles is disclosed. The conducting properties of such field-structured materials can be precisely controlled during fabrication so as to exhibit a large change in electrical conductivity when subject to any environmental influence which changes the relative volume fraction. Influences which can be so detected include stress, strain, shear, temperature change, humidity, magnetic field, electromagnetic radiation, and the presence or absence of certain chemicals. This behavior can be made the basis for a wide variety of sensor devices.

摘要： An electrode layer is formed on the upper surface of a first substrate, and a processing for partially removing the substrate is carried out in order to allow the substrate to have flexibility. To the lower surface of the first substrate, a second substrate is connected. Then, by cutting the second substrate, a working body and a pedestal are formed. On the other hand, a groove is formed on a third substrate. An electrode layer is formed on the bottom surface of the groove. The third substrate is connected to the first substrate so that both the electrodes face to each other with a predetermined spacing therebetween. Finally, the first, second and third substrates are cut off every respective unit regions to form independent sensors, respectively. When an acceleration is exerted on the working body, the first substrate bends. As a result, the distance between both the electrodes changes. Thus, an acceleration exerted is detected by changes in an electrostatic capacitance between both the electrodes.

摘要： A floating mass accelerometer having a plurality of curved elastic members tangentially contacting a mass that is supported by a low friction surface is disclosed. Proximity sensors are located adjacent the mass and provide an output based upon the distance between the sensor and the mass as regulated by the degree of elastic member compression or extension. Acceleration forces acting upon the mass cause the mass to move in response thereto, thereby causing deflection of at least one elastic member. The change in distance between the mass and at least one proximity sensor is relayed to a digital signal processor which processes the acceleration information and sends this information to a display and/or memory unit. In a preferred embodiment, a two axis accelerometer is disclosed wherein acceleration values greater than a predetermined level are stored in memory and may be recalled later to provide an indication as to acceleration forces encountered by the device. Alternative embodiments provide for an pre-impact monitor wherein a buffer holds acceleration information for the last time period; a shipping monitor wherein acceleration forces are time-tagged for later retrieval; a seismic monitor with an optional output relay capable of remote operations.

摘要： Angular motion sensor for sensing angular velocity components at higher frequencies. A first lower case member open at the top thereof supports a magnet therein for establishing a magnetic field oriented parallel to a central axis of the lower case. An insulating surface covers the magnet and a conductive liquid is disposed in a channel defined by the insulating surface and the lower case sidewalls. An upper case having an insulated inner surface including a sidewall structure complementary to the lower case sidewall structure forms a lid for the channel and is insulated from the lower case. The upper case is insulated from the conductive liquid, except at a hole in the insulation lying along a central axis of the lower case and upper case. Relative motion between the liquid mass and upper and lower case structures generates a voltage potential between the upper and lower cases, representing the relative velocity.
