Wireless Communication , Portable Devices and Use

Sammendrag/Abstract: The current state of development in portable devices and wireless technology has brought us to the brink of new era. Given the present frame of technological possibilities and opportunities within the market, it is inevitable that the times ahead will bear witness to the production of small, highly-specialized devices for highly specified areas of application. Many of these...

Server Controlled Power Management for Wireless Portable Devices

In this report we present a new power management infrastructure developed for the Linux operating system release running on the HP’s SmartBadge4 wearable computer. Based on this infrastructure, we implemented a new methodology for optimizing the energy consumption of wireless portable devices. The server knowledge of the workload is exploited to efficiently drive the wireless interface of the c...

VibeComm: Radio-Free Wireless Communication for Smart Devices Using Vibration

This paper proposes VibeComm, a novel communication method for smart devices using a built-in vibrator and accelerometer. The proposed approach is ideal for low-rate off-line communication, and its communication medium is an object on which smart devices are placed, such as tables and desks. When more than two smart devices are placed on an object and one device wants to transmit a message to t...

Touch-Aware Communication for Portable Devices

We have constructed an electronic circuit that makes a device touch-aware: it can communicate with a user’s wearable device if the user completes an electric circuit by touching it. Touch-aware devices are useful in ubiquitous computing environments for distinguishing between multiple individuals and devices. Our design is inspired by recent work by Zimmerman and by Matsushita in intrabody sign...
