TL;DR: In this paper, a rotating disc is used to measure the absolute rotation angle of a rotating shaft, and the signs of these electric signals are used to calculate a code characteristic of a low resolution absolute angular position.
Abstract: The device to measure the absolute rotation angle of a rotating shaft includes a rotating disc, fixed to the shaft. A group of permanent magnets of different sizes and polarities is disposed on a circular track. Further, a group of Hall sensors, fixed to a static part of the device, are disposed on a circular path, in proximity of the rotating disc magnets tracks, and generate electric signals proportional to the strength of the magnetic field produced by the magnets in proximity. The signs of these electric signals are used to calculate a code characteristic of a low resolution absolute angular position. Two analog signals are associated to the obtained code, according to a pre-defined table. The associated analog signal having the closest value to zero is used as an entry to a pre-recorded table containing the correspondent angular position of the shaft.

TL;DR: In this paper, a flexible and nonfunctionalized low cost paper-based electronic system platform fabricated from common paper, such as paper based sensors, and methods of sensing using the paperbased sensors are provided.
Abstract: A flexible and non-functionalized low cost paper-based electronic system platform fabricated from common paper, such as paper based sensors, and methods of producing paper based sensors, and methods of sensing using the paper based sensors are provided. A method of producing a paper based sensor can include the steps of: a) providing a conventional paper product to serve as a substrate for the sensor or as an active material for the sensor or both, the paper product not further treated or functionalized; and b) applying a sensing element to the paper substrate, the sensing element selected from the group consisting of a conductive material, the conductive material providing contacts and interconnects, sensitive material film that exhibits sensitivity to pH levels, a compressible and/or porous material disposed between a pair of opposed conductive elements, or a combination of two of more said sensing elements. The method of sensing can further include measuring, using the sensing element, a change in resistance, a change in voltage, a change in current, a change in capacitance, or a combination of any two or more thereof.

TL;DR: In this paper, a function-safety-oriented redundant current input module is proposed to support a redundant work mode, and when the redundancy work mode is employed, the diagnosis coverage rate and the overall safety requirement can be further improved.
Abstract: The invention provides a function-safety-oriented redundant current input module. The current input module supports a redundant work mode, and when the redundant work mode is employed, the diagnosis coverage rate and the overall safety requirement can be further improved. Two 4-20 mA redundant current input modules are provided; when the two modules are in the redundant work mode, the two modules simultaneously acquire, convert, and process the same 4-20 mA current, a measuring result is transmitted from the modules to a main module via a communication unit and processed by the main module, and the actual current value is expressed by the sum of the current values acquired by the two modules. When one module has a fault, the module with the fault is disconnected with a switch connected with a sampling resistor, input current is prevented from flowing into an input channel of the module with the fault, the module with the fault also informs the normal module of the fault via the communication unit, related function of the main module is realized via the normal module, and the actual current value is expressed by the current value acquired by the normal module.
