    Abstract: An apparatus for sensing a force. The apparatus includes a nanostructure being suitable for emitting electrons and a collector. The collector is proximately positioned with respect to the nanostructure so as to receive the emitted electrons and define a gap therebetween. The gap is partially dependent upon the applied force and the emission and reception of the electrons are indicative of the applied force.

    Abstract: A force detecting microsensor (12) comprises a single crystal Si substrate (14), a single crystal cone (16) formed on the substrate (14) and a resilient electrode mounted above the tip of the Si cone (16). The space between the tip of the Si cone (16) and the resilient electrode is maintained in a vacuum environment and the distance between the tip and the resilient anode is in the order of a few atomic diameters. The tunneling effect of electrons occurs between the tip of the Si cone (16) and the resilient electrode when a potential is applied to the resilient electrode and the Si cone tip. The resilient electrode deflects as a result of the force acting on the microsensor (12) which alters the electrical characteristics between the resilient electrode and the Si cone tip. The changes in the electrical characteristics can be measured to determine the level of force acting on the microsensor (12). The process for making the microsensor (12) according to the invention comprises the steps of forming an insulating layer (20) and support layer (24) on the substrate (14), forming a recess (22) in the insulating layer (20) and aperture (27) in the support layer (24) depositing a single crystal Si cone (16) on the substrate (14) and fully enclosing the Si cone (16) within the recess (22) of the support layer (24) and the insulating layer (20).

    Abstract: Systems and methods for determining the instantaneous force generated by a motor. In one embodiment, AC power (e.g., three-phase power) is provided to a linear motor of an ESP. An instantaneous current for each of the phases is measured at a particular point in time. These instantaneous current vectors are used to determine an instantaneous force by, for example, computing a root-mean-square of the instantaneous current vectors and multiplying the root-mean-square by a power factor. The instantaneous force computation may be performed successively for multiple, distinct points in time, and these computed force values may be used to form a graphical representation of the force generated by the linear motor over the stroke of the motor. The computed force values may also be used as the basis for controlling the motor.

    Abstract: A surface mounted monitoring system is disclosed that is useful for detecting the presence of both ordinary and excessive loads on a surface, and for providing real-time or near real-time trending data. The system includes an array of force transducers disposed on the exterior surface of a structural member such as a roof. In an exemplary embodiment, transducers may be placed on an interior surface, such as embedded within insulation. The force transducers detect the magnitude of a load force acting on the surface. A data analysis module (DAM) may record force readings in a circular memory buffer, so that recent data can be recovered in the event of a catastrophic collapse. The DAM may also communicate with a monitoring device that can display real-time loading data to a user and perform other analysis.

    Abstract: Die Erfindung bezieht sich auf einen Dehnungsmesser zur Messung der Dehnung einkristallinen Halbleitermaterials. Auf dem einkristallinen Halbleitermaterial soll zur Anzeige der Dehnung des Halbleitermaterials ein Signalgeber mit hoher Empfindlichkeit, d.h. hohem Signalanteil bei kleinem Störgrössenanteil angebracht werden. Das Problem wird durch einen als Signalgeber eingesetzten MOSFET gelöst. Es wird mittels einer Konstantstromquelle (als Mittel zur Erzeugung eines konstanten Source-Drain-Stromes) der Source-Drain-Strom konstant gehalten und die sich ändernde Source-Drain-Spannung gemessen. Die Änderung der Source-Drain-Spannung ist Mass für die Dehnung.
