MTD3L - A Low Overhead Secure IC Design Methodology
With the increasing use of portable devices and the increasing need for security in these devices, side-channel attacks are an increasing threat. Traditional circuit design techniques leave otherwise secure systems vulnerable due to the characteristics of the circuits, rather than weaknesses in the security algorithms themselves. These characteristics, called side-channels, are exploitable because they can be measured and correlated with processed data, potentially giving an attacker insight into the device's secret data. Alternative design techniques such as dual-rail asynchronous designs are capable of minimizing these potential side-channels by decoupling them from the data being processed. However, these techniques are either expensive to implement compared to standard designs or leave exploitable imbalances in the dual-rail implementation itself. Multi-Threshold Dual-Spacer Dual-Rail Delay-Insensitive Logic (MTD³L). presented in this thesis, offers the security by balancing side-channels both in general and between the dual-rail signals themselves as well as a reduction in circuit overhead comparable to previous design techniques. Results show that the Advanced Encryption Standard cores designed using MTD³L exhibit similar security to previous secure techniques with less design overhead.

Visual field examination using a video projector: comparison with Humphrey perimeter
To present a method of visual field examination using a video projector. Also, we compare our results with those of a Humphrey perimeter, which is accepted as standard in automated perimetry.
Software implementing a full-threshold 4-2-step staircase algorithm for the central 30-2 of the visual field (76 points) has been developed and tested in nine eyes of seven patients using an Epson TW 700 video projector. The results were compared to those obtained from the same patients using the Humphrey perimeter.
High correlation between the video projector visual fields and those of the Humphrey perimeter was found. The point-to-point correlation coefficient ranged from 0.75 to 0.90, with P<0.0001 for each eye.
Visual field examination results using a video projector have high correlation with those of a Humphrey perimeter. The method is possibly suitable for clinical use.

Design for Portable Virtual Instrument with USB Interface
This paper introduces the design process of a new type of portable virtual oscilloscope and signal generator, including both the hardware and software design. The data collecting board centers around the new generation of highly integrated C8051F020 and the VB program developed. The USB communication mode has been applied between the data collecting board and computer. This virtual instrument integrates together the perfect function if signal generating, data collecting, real-time data curve display, data storage and playback, analysis afterwards, etc.

TAKING TECHNOLOGY IN HAND
Personal digital assistant (PDA) technology has been on the market just 2 years. Yet already these portable, battery-powered computers - capable of converting notes written by hand on their small screens into lettered text - have helped speed up and streamline operations at a number of companies. Widespread use of cellular communications to access the Internet or corporate local networks will enhance PDA usage in the next 2 years, as people become comfortable with the technology.

Ottawa Hospital boss urges staff to 'be bold ... go big'; Information technology systems at The Ottawa Hospital were on life support before Dale Potter signed on. The IT expert's revolutionary ideas have transformed the institution
Other recent technological changes include: n An Nav Canada inspired tracking system for surgical patients. n The mass integration of all hospital campus computer networks. n The automation of surgical tool distribution. According to hospital chief executive Dr. Jack Kitts, it all started with his chance meeting in 2007 with a Harvard University researcher at a health-care conference.

Phil Wherry, RBTI CTO, commented, ''Now, the same system that we designed from the ground-up to maximize utility and minimize waste associated with individual and corporate business travel can actually make the comparison, booking and ongoing notification and update process virtually effortless.'' He continued, ''The mTravel Assistant(r) knows your ''likes'' and ''dislikes'', such as preferred hours of travel, and how to optimize your travel arrangements for such things as flight duration versus preferred airline or ticket price versus airport convenience. The mTravel Assistant(r) even watches how the travel selections you make change over time and adjusts the scoring of your travel arrangements accordingly, just as a personal assistant would.'' Using proprietary adaptive algorithms developed by the Red Branch technology team, mTravel Assistant(r) scores, or ''ranks'' all travel options presented to the traveler, the highest scoring arrangements appearing first based on a rich set of initial preferences and ongoing ''learned preferences'' observed over time. The system even features a ''single click'' search and booking option that presents the optimum itinerary Air, Car and Hotel, in a travel universe of seemingly limitless options, all in less than 35 seconds. ''Red Branch Technologies takes the business traveler's perspective into account for every product or feature we build,'' says Doug Foran, President/CEO. ''The mTravel Assistant(r) embodies that commitment and uses a new technology to make business travel easier. Optimizing an itinerary requires the consideration of countless variables. Most travel tools, online or off, have built- in ''biases'' that favor particular vendors and/or factors. The mTravel Assistant(r) is truly adaptive, works exclusively for the travelers' best interests and gets the arrangements they want at the prices they need.'' He continued, ''We are excited at the finalization and implementation of the baseline mTravel Assistant(r) functionality and expect to introduce new capabilities on an ongoing basis as part of our commitment to be ''With You All the Way.''
