As videos are more and more frequently played on mobile devices, a new-generation digital set-top box (STB) should provide TV users the streaming services additional to the conventional broadcast channel services. The inclusion of streaming services impose two imperative challenges for STB systems. First, the bandwidth should be efficiently distributed to multiple mobile users. Second, the system...
A plane antenna suitable for Bluetooth headsets is proposed. An asymmetric coplanar waveguide ground plane was used to achieved a bidirectional radiation pattern. An impedance bandwidth of 223 MHz (9%) covering the ISM band (2.4–2.484 GHz) was obtained. The peak gain of the antenna was 3.2 dBi.
This paper presents a wireless cross-platform interactive home automation system for long-term care facilities, based on the commercially available card-size embedded systems Banana Pi M1 and Intel® Edison.
This paper proposes a vehicle blind spot detection (BSD) system to reduce the traffic accident when car was changing lanes on the road. The cameras are installed at the bottom of the left and right side view mirrors. The system reaches 99% vehicle detection rate and is applicable during daytime and nighttime without high-cost radar. Furthermore, the system integrates with functions of auto cycle video...
In recent years, artificial intelligence technology has developed rapidly, and deep learning has been widely used in many areas. The performance of deep learning is particularly prominent in image recognition. This paper proposes a method to achieve efficient image recognition based on deep neural network using a small amount of data, which can be applied to home access control systems. The recognized...
The inaccuracy of CNC machining may come from several factors, such as machine vibration, dynamic stiffness, and thermal expansion. Once a workpiece is machined inaccurately, we can modify the NC program to generate compensation tool paths, and then perform the finishing process. However, the modification of the NC code is time-consuming, and the results may not be satisfactory as well. We propose...
We have been developing a system, called Tour Miner, which mines tour plans from SNS. It consists of two functions: mining and smelting. The mining function searches SNS for a given keyword and discovers travel records related to the keyword. The smelting function combines the travel records and extracts tour plans from the combination. In this paper, we elucidate the implementation of the smelting...
In this paper, we proposed a seam carving based refinement method to refine and produce superpixels. The proposed method can refine existing superpixels by repeating the splitting process. There are two major steps. The first is choosing a superpixel candidate by analyzing color variances; the second is splitting a superpixel into 4 by dynamic programming. The experimental results show that the proposed...
This paper presents an ultra-high-speed/area-efficient Polar encoder design with very high system throughput for emerging next-generation 5G applications. In a demonstrated design example, the proposed hardware architecture is mainly based on 16-parallel radix-2 processing engines. An 8192-point Polar encoder is designed and synthesized with TSMC 40-nm CMOS technology, operating at clock frequency...
More and more network services integrate the cloud platform to deliver their services. In order to accelerate the data sharing among users, data are usually divided and encapsulated into small pieces before delivery. However, the cloud file system enlarges the basic block size for maximizing the access throughput. This conflict between network transmission and cloud file system may induce high fragmentation...
The study applied water mist as the projecting medium and two projectors with different circular polarization in order to present 3D image. The system in this study is miniaturized for higher practicability, and judged the image quality by PSNR analysis.
This paper presents the modified least squares iteration (MLSI). It is calculated by the least squares and trilateration to reduce positioning errors. In this study, environment model curves build to estimate the distance by ZigBee received dB value. Then, use trilateration to measure distance of reference and destination nodes. When the position errors appear, it will affect the obtained trilateration...
The previous design of a 360-degree side view (panoramic) endoscope uses many mirrors/lenses to capture side view and forward view simultaneously. This paper proposed a lower-complexity panorama image system at the endoscope. We propose a parabolic mirror as a reflector in the new endoscope for a 360-degree side view. The proposed scheme has less mirrors/lenses, thus less lens msialignment and image...
This paper presents a novel startup circuit that provides a startup operation for bias circuits and reference circuits. The proposed circuit employs delay buffer and series transistors to automatically turn off the startup circuit after the bias circuit has started. Thus, the proposed startup circuit consumes no power during the normal operation of the reference circuit and is useful for low-power...
A three-lead electrocardiogram acquisition system is constructed with an analog front-end circuit (ADS1293), a microprocessor (MSP430X), and a personal phone or computer. The acquired three-lead (namely, Lead I, Lead II, and Lead V1) ECG data can not only be displayed on a personal computer by a MATLAB simulator but can also be stored in the cloud.
Multi-channel module heart rate and EMG clinical human-computer interaction system was using Wi-Fi mobile network transmission of physiological signals. With Grove-EMG, you can send a general physiological signal to a mobile device. System achieved real-time monitoring function for the monitoring of a number of physiological data to monitor the integrity of the monitoring. Hospital Network We uploads...
Advanced driving assistance systems (ADAS) have developed in widespread use for traffic safety, they must include mechanisms functioning in bad weather conditions. However, the rain reduces visibility and degrade the effectiveness of computer vision algorithm when they are vision-based methods. We propose an orientation-adaptive non-local mean (OA-NLM) filter algorithm to further improve rain removal...
A method for chip and system design of data packet decoding and analyzing for User Datagram Protocol (UDP) on Velodyne LiDAR Puck-16 (VLP-16) is proposed. We decode the 3D LiDAR information, which transmits the UDP format of data packets. The results will get the distance, angle, reflectivity, and time stamp. Above of all results can perform the point cloud of the coordinate system in the 3D environment.
Based on the computer vision and neural network techniques, we propose a driver assistant system for automatic detection and recognition of Chinese traffic panels on highway. In detection stage, search regions are reduced by a simple ROI setting and traffic panels are efficiently identified by proper HSV color thresholding. In recognition stage, individual English characters are first located as maximally...
