摘要： A sensor system and method of reducing plasma-induced communication inhibition for a main antenna includes using auxiliary antennas for detecting a density of plasma that affects operation of the main antenna, and re-orienting an electromagnetic field around the main antenna in response to the density detected to reduce effect of the plasma on the main antenna. The auxiliary antennas are also operable for data link communication and switchable such if the density of the plasma inhibits receipt or sending of signals by one of the auxiliary antennas, another one of the auxiliary antennas may be used for data link communication.

摘要： A thickness detection device for sheet-type medium includes a fixing frame, a reference shaft and a detection assembly shaft. A reference roller is fixedly sleeved on the reference shaft. At least one detection roller is provided on the detection assembly shaft, and the detection roller is in an elastic contact with the reference roller. The detection roller is sleeved on the detection assembly shaft by a bracket, the bracket has an elongated hole through which the bracket is sleeved on the detection assembly shaft, an elastic element is provided between an end of the elongated hole and the detection assembly shaft, and the elastic element enables the detection assembly shaft to elastically maintain a certain distance from the end of the elongated hole. Thus, thickness signal obtained is not interfered by banknote displacements in other directions, and thickness detection of the full banknote can be achieved.

摘要： A device for film thickness measurement and a method for film thickness measurement are disclosed. The device includes a planar indenter, a collecting unit and a processing unit. The planar indenter includes a base plate and a piezoelectric film layer. The collecting unit includes a plurality of collecting circuits evenly distributed above the piezoelectric film layer and spaced from each other. The collecting circuits are used for collecting current signals generated when the piezoelectric film layer deforms at positions corresponding to the collecting circuits. The processing unit is used for calculating a film thickness of the film sample to be measured based on the current signals collected by each of the collecting circuits.

摘要： A system and method for determining a change in a thickness and temperature of a surface of a material are disclosed herein. The system and the method are usable in a thermal protection system of a space vehicle, such as an aeroshell of a space vehicle. The system and method may incorporate micro electric sensors arranged in a ladder network and capacitor strip sensors. Corrosion or ablation causes a change in an electrical property of the sensors. An amount of or rate of the corrosion or the ablation and a temperature of the material is determined based on the change of the electrical property of the sensors.

摘要： Techniques are described to determine a thickness of individual layers of a plurality of metal layers that include a first metal layer disposed on a polymer material and a second metal layer disposed on the first layer, such that the first layer is between the polymer material and the second layer. A measurement device may determine a resistance of the plurality of metal layers and calculate (e.g., estimate) a thickness of the individual layers based on the resistance of the individual layers and based on a resistivity of individual metals used in the plurality of metal layers. The measurement device may determine whether the individual thicknesses are within predetermined thickness ranges to determine whether to pass a quality control test.
