Howling control is a critical part of any public-address (PA) system. To detect a howling frequency of a PA system before having howling, the author has previously proposed an effective method based on spectral accumulation. This paper shows some results of the howling detection through a practical experiment. In this practical experiment, the proposed method was able to estimate the coloration frequency and eliminate the coloration by the notch filter.

In this paper, we design a new mobile traffic warning triangle (MTWT) which consist five parts: distance measurement unit, reflective tracking function, LED indicate, emergency calling and embedded controller. The MTWT can track the white line in road side then move a fix distance and rise the LED indicate triangle. It also can detect the distance between two cars and alarm the driver. The GPS module let system understand its current location that makes it easy to calculate the movement orientation and to inform the relevant departments. The driver can call back the MTWT just use application software in the smartphone when system finish the notification.

A mobile robotic access point (AP) is proposed to provide better wireless network environment. This AP automatically searches and moves to the best position to provide enough radio power for all devices connected to the AP. We designed the mobile robotic AP and evaluate its performance in experiment. It was found that the proposed AP can increase radio power for all devices connected to the AP by searching the best position of the AP. The obtained result suggests that the proposed AP is suitable to provide comfortable Wi-Fi network environment in indoor environment.

We have proposed a simple vehicular information acquisition scheme using infrared radar and reflector code in order to recognize vehicle information with low cost. However, since the size of the reflector code is so large and the number of code patterns is not so large, it is necessary to reduce the size and increase the patterns in order to be attached with vehicles. So we propose a new scheme using subdivided reflector code.

As a trend, our everyday goods are changing to program-controlled ones from pure mechanical or electrical ones. The concept of `coded object' was proposed for such a new generation product by Kitchin and Dooge. We propose a novel interaction method using OCR for coded objects, which is aimed at simplifying the operations on the configuration of coded objects and making the recording, sharing, and distribution of the configurations universal. We constructed a prototype for proof-of-concept using a digital SLR (single lens reflex camera). In this prototype, we utilize open-source OCR engine “tesseract” trained by handwritten character images and adding a preprocessing of projective transforms in order to cope with free angle capture by the camera. This prototype can be configured by shooting handwritten texts.

A sports motion support system for golf swing has been described by using a perceptive sportswear and a wireless mobile device with Android application, in which a trainee is given real-time auditory feedback to be informed the performance of the swing. The wireless mobile device receives motion data from the perceptive sportswear designed in form of shirts and shoes in which hetero-core optical fibers are fastened or embedded for monitoring the body motion without restraint. Real-time feedback experiment has been demonstrated based on the system, in which the trainee performing golf swings could efficiently improve his swing motion.

Device-to-Device communication allows two cellular devices to communicate with each other without a base station. By relieving the base station from relaying data to and from different devices, D2D communication aims at increasing the system capacity. In a D2D enabled network, one of the critical issues is to effectively allocate frequency resource. In this paper, a resource allocation scheme has been proposed that increases the throughput of all devices by using Fractional Frequency Reuse.

Because of the accident of falling out of the bed of inpatients / recipients of care occurs constantly in nursing /care facilities, the technique of roll-over detection / posture state estimation are required. In this paper, we developed the detection technique of roll-over with the thermographic watching system with the respect of a person's privacy The detection of roll-over is the method which finds out the errant characteristic value of the thermography. By using the Higher-order Local Auto-Correlation (HLAC) as the characteristic value, several of rollover and awaking was detected.

Recently, eMMC is widely being used in mobile devices because of its characteristics such as low cost, small size, and low power consumption. In this paper, we analyze features of eMMC based on commands such as Trim, Discard, and Background to investigate how do commands affect the random write performance and lifetime of the NAND flash memory. Also, we propose a method that uses the Background command to improve the random write performance of eMMC. Our experimental results clearly show that our method outperforms the normal power-off method, on average, by 173% in terms of the random write performance.
