Large substrate currents could induce the device melt in power manager integrated circuit applications. Many researches are focused on how to reduce substrate currents from process modifications. In this paper, the fundamental substrate current mechanism analyses are studied. Then, a tracing-high voltage between the device drain terminal and the device source terminal applied on the isolation ring is proposed for substrate current reductions. Engineers can apply this method for avoiding the device burned-out without the complicated process changes.

The interaction between the virtual world and the real world has received continuous attention in recent years, and this type of interaction has often been found unidirectional or asynchronous. By reviewing the literature, this study explained our view of the virtual world, as well as the necessity of media and the directional connection in the interaction of the two worlds. To validate our design concept, we created a wall in the virtual world that can be instantly synchronized and interact with the monitor in the real world. Based on our findings in the design process, we also proposed applying the concept to more senses in the future.

Android operating system adjusts its screen view orientation based on the angle to the gravity of the device. This function has kept similar behavior without large modification for a decade. We think that this implementation has room for improvement. For example, this implementation is too pessimistic for some users and makes a user wait for a while for its screen's view rotation after the device rotation. In this paper, we propose a method for quickly adjusting screen orientation. The proposed method predicts the angle of the device in the near future from the recently measured acceleration. We then show that our proposed method can adjust the screen view orientation sooner by 0.38 s than the original implementation and its negative effect of miss rotation is small.

The matching situation with AND operations between two parties is a common application in card-based protocols, and it is known to provide a non-embarrassing confession of love. This means that the other party does not know whether the input was 0 or 1, which is said to avoid embarrassment. In this paper, we consider an extended AND protocol that extends the usual AND operations with two input choices, 0 and 1, to allow the input of a third value, “indefinite,” which is neither 0 nor 1. Considering the continuity of the protocols, it is better to design them to satisfy the transitivity law, and in practice, we need to deal with the classification of three-element semigroups. We attempted a complete classification with restrictions to have a local AND structure, and found that except for trivial examples and considerations of the algebraic isomorphism, we could reduce the classification to only seven cases. These include cases of three-valued logic by Bochvar and Lukasiewicz respectively. We also discuss some examples applied to the card-based protocols that have been devised. The examples are based on the same pattern cards with indistinguishability on the backside, which is another card protocol different from the general encoding rules.

FPGA technology and dataflow approach offer the potential for high performance in many applications including IoT-connected consumer electronics and so on. A dataflow approach inherently brings the potential for parallel execution of programs. In our laboratory, we have developed a ring interconnected multicore dataflow DSP called LSC-Based DSP. In this work, we design LSC-Based DSPs with two different kinds of loop iteration mechanisms. We implement these our DSPs on an FPGA and measure the execution time of a test program.

Heart disease poses a great threat to the health of an individual and even leads to sudden cardiac death, and hence a ubiquitous and portable tool for early detection and warning is of significant value. Benefiting from the speedy advance of sensor technology, artificial intelligence, and internet of things, we have developed an intelligent system that can remotely collect heart sounds, process the signals, and predict common cardiac diseases with the trained machine learning model. In this study, we detail our designed smart stethoscope and show the system architecture and its components. Besides, initial results demonstrate its power.

Path planning is the research focus of robot development and design. As technology advances, mobile vehicles for various jobs are used in different environment. Therefore, it is an important research to plan an optimal path that is able to avoid obstacles and consider time and distance to reach the goal. In this paper, to improve the efficiency of mobile vehicle path planning, the Voronoi diagram is used to describe the map, and the shortest path tree is built by Dijkstra algorithm. Re-planning path task is activated when moving obstacles approach the mobile vehicle. The collision-free A* algorithm that take account of the directions and positions of the moving obstacles will effectively avoid collisions and find optimal path according to the shortest path tree. In the simulation results, there are several random moving obstacles in the map to simulate the complex dynamic environment. The mobile vehicle could reach the goal without any collisions, and only add a small amount of time and distance.

In this paper, we propose a light-weight convolutional neural network based on depth-wise separable convolutions and cross stage partial (CSP) network. Dissimilar to MobileNetV3, the proposed network is composed of some CSP blocks to reduce the model size and computational operations. For performance evaluation, Cifar10 and Cifar100 are used for testing. Compared to MobileNetv3, the model size and execution time of the proposed network in PC and mobile device are smaller. Therefore, the experimental results show that the proposed light-weight network can effectively extract visual features for image classification compared with MobileNetV3.

The recent experience in the use of virtual reality (VR) technology has shown that users prefer Electromyography (EMG) sensor-based controllers over hand controllers. The results presented in this paper show the potential of EMG-based controllers, in particular the Myo armband, to identify a computer system user. In the first scenario, we train various classifiers with 25 keyboard typing movements for training and test with 75. The results with a 1-dimensional convolutional neural network indicate that we are able to identify the user with an accuracy of 93% by analyzing only the EMG data from the Myo armband. When we use 75 moves for training, accuracy increases to 96.45% after cross-validation.

In-network caching is a technology that enables intermediate routers to store contents. Clients can download the contents from the routers in addition to content servers. Considering optimal placement of servers and contents leads to improve responsiveness and save network resources. This paper discusses joint optimization of server and content placement problems for in-network caching. We formulate integer linear programming to simultaneously determine the location of content servers and content caching. Through numerical experiments, we examine the performance of the joint optimization.
