Event-based cameras have increasingly become more commonplace in the commercial space as the performance of these cameras has also continued to increase to the degree where they can exponentially outperform their frame-based counterparts in many applications. However, instantiations of event-based cameras for depth estimation are sparse. After a short introduction detailing the salient differences and features of an event-based camera compared to that of a traditional, frame-based one, this work summarizes the published event-based methods and systems known to date. An analytical review of these methods and systems is performed, justifying the conclusions drawn. This work is concluded with insights and recommendations for further development in the field of event-based camera depth estimation.

This paper proposes a new IDD sensor for built-in self-test (BIST) applications for digital, analog, and mixedsignal circuits. This novel, wide-band, nonintrusive, process and temperature-stable IDD sensor operates up to 230 MHz, which is 2.3 faster than previously proposed designs, and occupies 78.3% less area than another competing design. A BIST utilizing this novel IDD sensor is created and tested on numerous digital circuits, as well as on an op-amp and a mixer, achieving up to 90% fault coverage, while maintaining the performance of the circuitunder-test. The experiments were implemented in 0.18-m TSMC CMOS mixed-signal technology.Index Terms-Built-in self-test (BIST), CMOS mixed-signal circuits, design for testability (DFT), sensor.

This article presents and describes in detail an interactive method of teaching and gathering feedback from students by applying internet-based survey systems and utilizing smart devices. Real-time survey results are monitored and analyzed by university staff and the lecturers, and these results are visible to other students as well. The presented method is probably the fastest and easiest way to receive feedback from students while increasing their interest and participation in lectures and laboratory work. The proposed method combines multiple means of gathering feedback from students, which include surveys, consultations, and group discussions. This interactive method has been applied for 5 years at the Faculty of Electronics, Vilnius Gediminas Technical University, Vilnius, Lithuania. After analyzing 10 years of available statistical data, which included 5 years when the presented interactive survey method was applied, a 4-6% increase in student performance was observed. Therefore, we conclude that this is perhaps a direct consequence of applying the discussed interactive method. In addition, after analyzing student surveys, it has been observed that 86.37% of students evaluated the use of smart devices positively in conjunction with this teaching method process. The students also positively evaluated the teaching process overall, and highly encouraging responses were received to questions asking to rate class activities and class atmosphere using this interactive survey method-87.79% and 91.68%, respectively. A large number of positive responses reflect a positive student attitude towards the use of such interactive surveys in the study process and supports their benefits aimed at increasing the overall quality of education.
