Image sensors based on the CMOS technology became commonly used sources of image information in PC-based vision systems. Image information is converted directly on the chip to a stream of synchronous digital data which can be transferred to a PC using the cost-effective interface introduced in this contribution. The CMOS image sensor together with the developed interface can be considered as a ...

This paper presents a low-cost microcontroller-based data acquisition device. The key component of the presented solution is a configurable microcontroller-based device with an integrated USB transceiver and a 12-bit analogue-to-digital converter (ADC). The presented embedded DAQ device contains a preloaded program (firmware) that enables easy acquisition and generation of analogue and digital ...

24 Published By: Blue Eyes Intelligence Engineering & Sciences Publication Pvt. Ltd. Abstract— Every user has its specific rhythm of typing which could be used as a biometrics in order to build some kind of "footprint" – unique profile. If somebody gets to know this profile, legitimate user is endangered by tracking and being impersonated. That is the way typing rhythm must be protected. We des...

This paper analyzes a vulnerability in the flash controller for secure USB drives, which is meant to enable secure USB drives to prevent unauthorized access to the data stored on them. This controller divides a driver into several partitions, one of which is configured as a secure area to store secret information. Generally, secure USB drives supporting multiple partitions may have three differ...

Ultra-wideband (UWB) technique has become one of the most fascinating technologies with various antennas. It has the merits of high speed transmission rate, low power consumption and simple hardware configuration over conventional wireless communication systems. The research and development of the UWB systems including antennas have been widely performed [1-5]. Recently, UWB systems have focuse...

あらまし 最近,UWB 技術を用いたワイヤレス PAN やワイヤレス USB を実現するための小形・広帯域の アンテナが多数提案されている.UWB 技術を用いたワイヤレス PAN では,3.1~10.6GHz の周波数を利用し て,高画質の動画をリアルタイムに転送することができる.また,ワイヤレス USBでは,USB によるデータ転 送をワイヤレス化するものであり,ディジタルカメラなどの大きな動画ファイルも UWB 技術により数秒で転送 が可能になる.いずれの用途においても,小形で広帯域のアンテナが必要になる.特にワイヤレス USB 端末で は,アンテナ放射素子部の最大寸法を 20 mm 程度以下とする要望がある.本論文は,ワイヤレス PAN やワイ ヤレス USB を実現するために,今まで報告されてきた小形・広帯域化技術を取り上げて紹介する.更に,その 中の有力なものについて,その...

Our project has two main parts; part one consists of reverse engineering the USB protocol of the X-Plorer guitar controller manufactured for use with the Microsoft c ©Xbox 360, and part two is implementing a USB driver to make the guitar available to applications running on top of the Linux kernel, with the specific goal of being able to use the X-Plorer guitar with the open-source game Frets o...
