Abstract:
The method of calibration of plants for verification of stopwatches with the help of the electronic-counting CNT-90 frequency meter is presented. The measurement circuits for verification (calibration) of reference plants for verification (calibration) of stopwatches are given. The device for synchronous start, which is based on the transformation of the motion signal of the moving part of the plant into an electrical signal of direct current using optical sensors, is used in the measuring circuit for calibration plants of mechanical stopwatches, and, the device for synchronous start, which is based on the transformation of the audio signal of an electronic stopwatch into an electrical signal of direct current using microphone, is used in the measuring circuit for calibration plants of electronic stopwatches. An example of the applying of the CNT-90 electronic frequency counter software is provided, which allows you to calculate the verification and calibration results (rejections the measurements of time and instability indexes) in the automatic mode. The calibration model and uncertainty budget for calibration of stopwatches are presented. The components of Type A and B, in accordance with calibration model are recorded when calculating the combined standard uncertainty in the form of standard uncertainties. The components of Type B: standard uncertainty due to the electronic counting frequency meter readings from the nominal value is taken from the calibration certificate of the frequency meter; standard uncertainty due to the drift of an electron-counting frequency meter since its last calibration; standard uncertainty due to the discreteness of indications of the plant indicator; standard uncertainty due to the effect of the device for synchronous start. The method of verification and calibration of installations for verification (calibration) of stopwatches, which are describe in the article, can be used in scientific metrological institutions, state enterprises, metrological services of state bodies, by enterprises and organizations, conformity assessment bodies of measuring instruments and in any other laboratories which have appropriate equipment and required standards.

Abstract:
The paper presents an approach for model-based black-box conformance testing of preemptive real-time systems using Labeled Prioritized Time Petri Nets with Stopwatches (LPrSwTPN). These models not only specify system/environment interactions and time constraints. They further enable modelling of suspend/resume operations in real-time systems. The test specification used to generate test primitives, to check the correctness of system responses and to draw test verdicts is an LPrSwTPN made up of two concurrent sub-nets that respectively specify the system under test and its environment. The algorithms used in the TINA model analyzer have been extended to support concurrent composed subnets. Relativized stopwatch timed input/output conformance serves as the notion of implementation correctness, essentially timed trace inclusion taking environment assumptions into account. Assuming the modelled systems are non deterministic and partially observable, the paper proposes a test generation and execution algorithm which is based on symbolic techniques and implements an online testing policy and outputs test results for the (part of the) selected environment.

With the price boost of goods and fuel, bycicles have become the first choice when it comes to energy conservation and pollution reduction and they even become the representative of fashion. In addition, inbound bycicle routes keep increasing with strong national support. Therefore, safety of cycling has become a crucial issue. In order to enhance cycling safety, the research aims at developing a wireless stopwatch with rear-viewed imaging function. Based on RF technique, the invention integrates the basic functions of wireless stopwatches on the market. A rider can notice the traffic behind at all times without turning his/her head back but through watching the LCD screen. Furthermore, while carrying a kid, the rider can ensure the safety of the child through wireless imaging. By increasing the concentration of the rider, the creation builds a better environment for cycling.

Abstract:
Abstract In recent years, wrist-worn devices that contain inertial measurement units have become prevalent. The data from these sensors can be used to estimate characteristics of manual processes in a manufacturing environment. The goal of this research is to determine cycle times of manually performed assembly processes using data from wrist-worn inertial sensors. Specifically, this work explores an unsupervised method of analyzing time series data to extract patterns (motifs) which represent individual cycles of an operation. From here, cycle time is computed by applying knowledge of the frequency of data collection. Testing shows that the mean cycle times obtained from stopwatch are statistically indifferent from those obtained from the proposed approach. Furthermore, results suggest that the proposed approach is insensitive to high frequency noise in the data. These encouraging results warrant further investigation and more testing.

Abstract:
This paper presents an energy-regenerative suspension device that is able to harvest some of the wasted energy that is generated in a suspension system. For a traditional road vehicle suspension system, shock absorbers are mainly dissipating energy to reduce vibration. The dissipated energy may be collected to improve the fuel economy of road vehicles. In this research, CarSim and Simulink are used to simulate and determine the harvestable energy in a conventional shock absorber under different operating conditions. A conceptual energy-regenerative absorber is designed and tested using a fabricated prototype. A variable speed motor is implemented to adapt the change of stroke length of a mechanism due to the various road roughness. Instruments, e.g., laser tachometer, pressure gauge, ammeter, voltmeter, and stopwatch, are used to collect data. The simulation and prototype testing results indicate that the proposed energy-regenerative suspension device could harvest dissipated energy to improve vehicle fuel economy.
