The calibration of Automated Test Equipment(ATE) is an important part of microelectronics measurement. To achieve full calibration of high-speed ATE, each high-speed digital channel should be traced to the calibration equipment. Calibrating each channel individually with an instrument will pose a great challenge to the calibration of ATE, and channel switching will increase a large amount of calibration time. This paper puts forward a design solution of calibration equipment of high-speed ATE, which can realize the versatility and portability of calibration equipment, and realize multichannel automatic calibration progress.

Rotating-coil magnetometers are among the most common and most accurate transducers for measuring the integral magnetic-field harmonics in accelerator magnets. The measurement uncertainty depends on the mechanical properties of the shafts, bearings, drive systems, and supports. In this paper we study the mechanical phenomena (static and dynamic) affecting rotating-coil measurements and propose analysis and diagnostic methods for improving the instrument in terms of material choice and geometrical design. The propagation of uncertainty is investigated on the measured quantities (induced voltages, integrated and developed into a Fourier series, the coefficients of which are know as field harmonics). This results in a consistent framework for the design of a measurement bench for rotating-coil magnetometers. The paper also presents the design of a complete system, including displacement stages, supports, rotating coils, and an angular position system.

The 4.0 paradigm has diffused across many sectors in a number of technological application fields, from industry to healthcare and constructions, and also to immaterial contexts, such as social events. The relevant enabling technologies of this paradigm are declined to adhere to the requirements of the specific field. Because 4.0 is often associated with technological advancement, in the literature, little attention has been dedicated to the adoption of 4.0 technologies in sectors that are not intrinsically technological. Starting from these considerations, the goal of this work is to address the possibility of extending the 4.0 Era paradigm also to fields that, by definition, are not technology-oriented, such as the craft sector. In particular, as a case study, the adoption of augmented reality (AR) to administer instructions to a workman in the manual assembly of a product is addressed. In line with the 4.0 paradigm, a dedicated workman-centered, AR application was designed, implemented and tested. As a case study, the manual assembly of a mechanical clock was considered. After describing the design strategies and the implementation modalities, experimental tests were carried out to measure the reliability of the AR-based system.

Wireless Sensor Networks (WSNs) have gained considerable popularity in industrial applications and are widely used nowadays in several industrial monitoring and control systems. To process and store the huge amount of data WSNs generate, most of the solutions opt for the Cloud approach as it provides suitable capabilities to deal with Big Data scenarios. However, as discussed in this paper, Cloud-based solutions have several drawbacks, e.g. latency and security, to name just a few. To overcome these drawbacks, we propose a system meant for monitoring of industrial assets based on the Fog computing paradigm. As shown in this paper, the proposed solution provides better performance in terms of reliability/accuracy and allows full control over the sensor nodes. The system provides also the ability to rapidly program the Fog nodes and update their business logic. Finally, the advantages of the proposed Fog-based solution are discussed considering a real-world industrial application scenario.

This paper describes experimental high capacitance simulator based on a mutual inductance. The standard was designed for calibration of battery impedance analyzers (EIS). The designed standard is equipped by a DC bias voltage source designed to simulate typical lithium battery cell. The DC bias source was designed so it does not affect properties of simulated impedance by its own internal impedance. The whole standard was designed for a frequency range from fraction of hertz to at least 5 kHz and it can withstand peak measurement current up to 2.5 A.
