| This paper introduces a novel new smoke detector characterized by its very small size and very high sensitivity. | |
09 Jun 1999 | Despite its simplicity, this new approach does not sacrifice the accuracy of the battery aging rate estimates since it accounts for temperature fluctuations experienced by batteries in the field. |
| However, basic battery dynamics, during a single discharge, cannot provide a true estimate of the actual lifetime of the battery, e. g., how its usability decreases due to long-term and irreversible effects, such as the fading of capacity due to aging or to repeated cycling. | |
| We develop a tailored numerical algorithm for the computation of the distribution of the consumed energy and show how different workload patterns influence the overall lifetime of a battery. | |
| Preliminary results show that the ion collection efficiency is low and that the detector performance is limited by a long dead time. | |
| If the nest remained active, flushing the bird and visiting the nest once did not appear to increase the likelihood of the nest being depredated. | |
01 Jan 2018 33 Citations | The IoT device can potentially last for more than 5 months (transmission interval of 30 seconds) on the coin cell battery (capacity of 120mAh) without any energy harvesting, sufficiently long for the dark seasons of the year. |
| The effects of observer-related nest abandonment may also reduce estimates of daily nest survival when time to nest fate is reduced and the average nest exposure period within the sample becomes shorter. | |
| Reasonable interpretation of these estimates, combined with the cost of a smoke detector and the risk of a fire death, places the smoke detector-based value of life saving in a range of $ 1.41 to $ 2.487 million 1986 dollars. | |
152 Citations | This 2 V battery shows an average specific capacity of 300 mAh g−1(S), a long cycle life, an expected low cost and high safety. |
149 Citations | In this paper, the authors of these two major studies jointly reconcile their previous conclusions by providing clarity on how methodologies to manage battery degradation can reliably extend battery life. |
| Test cases indicate that the scheme is capable of accurate reserve life estimation long before the end of battery life is reached. | |
21 Mar 2011 33 Citations | Experiments show that our model describes how the changes of system component states affect the battery lifetime, and that it improves the accuracy of online battery lifetime prediction. |
04 Mar 2012 31 Citations | Finally, through the experiments, obtained results for both a new and an aged battery demonstrate the accuracy of the methodology and how it can improve the battery's lifespan. |
63 Citations | The results demonstrated the sensitivity of the battery to long hours of work. |
01 Dec 2014 | This provides highly realistic, long-term predictions of battery response and thereby enables quantitative comparisons of varied battery use strategies. |
67 Citations | Experimental results show that the proposed four-stage smoke-detection algorithm outperforms conventional smoke-detection algorithms in terms of accuracy of smoke detection, providing a low false-alarm rate and high reliability in open and large spaces. |
29 Citations | It is shown that such a smoke detector is able to operate reliably under low concentration of smoke and high relative humidity conditions. |
101 Citations | Alarm algorithms utilizing ionization detector smoke measurements proved to be more effective than measurements from photoelectric detectors. |
