摘要： The invention relates to a method for determining an actual value and/or an actual value range of at least one state variable of a fluid in a fluid flow by means of at least one indicator particle (9) introduced into the fluid. In addition it is proposed that the at least one indicator particle (9) is designed and provided for an irreversible property change of an indicator property of the indicator particle (9) in the case of a certain indicator value of the at least one state variable in the fluid flow and/or as a clear function of the actual value when a certain period of time has elapsed after the indicator particle (9) has been introduced into the fluid, wherein the indicator particle (9) is detected at a detection point, the indicator property of the indicator particle (9) is evaluated and the actual value and/or the actual value range of the state variable is inferred from the indicator property upstream of the detection point. The invention also relates to a method for operating a fluid-guiding device (7), an indicator particle (9) and a device (7) for determining the actual value and/or actual value range of the at least one state variable.

摘要： An integrated device for physically unclonable functions is based on a set of MOS transistors exhibiting a random distribution of threshold voltages which are obtained by lateral implantations of dopants exhibiting non-predictable characteristics, resulting from implantations through a polysilicon layer. A certain number of these transistors form a group of gauge transistors which makes it possible to define a mean gate source voltage making it possible to bias the gates of certain others of these transistors (which are used to define the various bits of the unique code generated by the function). All these transistors consequently exhibit a random distribution of drain-source currents and a comparison of each drain-source current of a transistor associated with a bit of the digital code with a reference current corresponding to the average of this distribution makes it possible to define the logical value 0 or 1 of this bit.

摘要： An apparatus for determining or monitoring the fill level of a fill substance located in a container in a process, comprising: a signal producing unit; an in-coupling/out-coupling unit an antenna unit; wherein the antenna unit has a hollow conductor and an antenna element widening toward the fill substance and the antenna unit transmits high-frequency measuring signals in the direction of the surface of the fill substance and receives echo signals reflected on the surface of the fill substance; and a control/evaluation unit, which ascertains the fill level of the fill substance in the container based on travel time of the measuring signals. In or on the antenna unit a process isolation is provided, which is at least approximately transparent for the high-frequency measuring signals and which protects the in-coupling/out-coupling unit against influences of the process. The process isolation is an isostatically pressed, molded part, which is manufactured of at least two plastics having different physical and/or chemical properties.

摘要： A device and technique for impact detection and indication includes a housing; a mass member located within the housing, the housing configured to enable movement of the mass member from a first position to a second position within the housing in response to receipt by the housing of an acceleration event; and first and second biasing members disposed within the housing and biased toward each other to retain the mass member in the first position. In response to receipt by the housing of the acceleration event, the mass member is configured to overcome the biasing force of the first biasing member and move from the first position to the second position, and wherein the first and second biasing members each comprises a leaf spring member having a length greater than a width of the mass member and disposed transversely to a direction of movement of the mass member.

摘要： A fault indicator for indicating the occurrence of a rapid pressure surge within a housing of an electrical device has: a barrel capable of being mounted in an aperture of the housing; an actuating mechanism having a chamber with at least one orifice communicating between interior and exterior surfaces of the chamber within the housing and an actuating member movable in response to a pressure differential between the interior and exterior surfaces of the chamber; a plunger within the bore of the barrel biased outwardly in the barrel and normally retained in an armed position by the actuating member; and a radial seal disposed between the plunger and the barrel. When the pressure differential exceeds a positive threshold value, the actuating member is moved and thereby permits the plunger to move outwardly into a triggered position. The radial seal may be a dual-lip seal.

摘要： In the method and circuit arrangement for offset correction of the measurement bridge, the full bridge signal and half bridge signal of the measuring bridge are measured; a self-adjustment of the half bridge signal path to an output signal of the full bridge signal bath is performed to adjust the half bridge signal to the full bridge signal for each measurement cycle between turn on and turn off of the measurement bridge; and an offset value of the half bridge signal path is determined at a time of turning on and the offset value is kept constant during a given measurement cycle.
