05 Dec 2004TL;DR: The purpose of this work was to obtain a component-wise breakdown of the power consumption a modern laptop and found that reducing the backlight brightness can reduce the system power significantly, more than any other display power saving techniques.
Abstract: The purpose of this work was to obtain a component-wise breakdown of the power consumption a modern laptop. We measured the power usage of the key components in an IBM ThinkPad R40 laptop using an Agilent Oscilloscope and current probes. We obtained the power consumption for the CPU, optical drive, hard disk, display, graphics card, memory, and wireless card subsystems–either through direct measurement or subtractive measurement and calculation. Moreover, we measured the power consumption of each component for a variety of workloads. We found that total system power consumption varies a lot (8 W to 30 W) depending on the workload, and moreover that the distribution of power consumption among the components varies even more widely. We also found that though power saving techniques such as DVS can reduce CPU power considerably, the total system power is still dominated by CPU power in the case of CPU intensive workloads. The display is the other main source of power consumption in a laptop; it dominates when the CPU is idle. We also found that reducing the backlight brightness can reduce the system power significantly, more than any other display power saving techniques. Finally, we observed OS differences in the power consumption.

TL;DR: Teaching and learning activities in 4th and 5th grade classrooms that were permanently equipped with one laptop for each student and classrooms that share a cart of laptops that create a 1:1 laptop environment on a temporary basis are compared.
Abstract: This study compares teaching and learning activities in 4th and 5th grade classrooms that were permanently equipped with one laptop for each student and classrooms that share a cart of laptops that create a 1:1 laptop environment on a temporary basis. The study originated from a question posed to us by Andover Public Schools (MA): “How does teaching and learning differ when upper elementary students (4th and 5th graders) are provided with their own laptop computers?” In response to this question, we undertook an intensive two month study that employed a mixed methodology that included student surveys, student drawings, teacher interviews, and 56 structured classroom observations. The findings summarized in this article provide evidence of several differences in teaching and learning activities between the two settings. Classrooms that were fully equipped with 1:1 laptops showed more technology use across the curriculum, more use of technology at home for academic purposes, less large group instruction, an...

TL;DR: Results indicate that laptops integrated in teaching can enhance learning and motivation in schools, at least after 1.7 years of introduction, but health risks must be considered.
Abstract: Effects on cognitive performance, social atmosphere, communication, motivation and aspects of strain were investigated when laptops were integrated in classrooms. According to a quasi-experimental design 27 laptop students were compared with 22 non-laptop students from the same high school, aged 17-18 years. Results of tests and questionnaires showed that laptop students had better spatial abilities and computer skills, furthermore higher participation, learning interest, motivation and pressure to perform were found in laptop classrooms. However, laptop students experienced greater physical discomfort, particularly in their arms, but concerning creativity, social intelligence and mental stress no group differences occurred. Results indicate that laptops integrated in teaching can enhance learning and motivation in schools, at least after 1.7 years of introduction, but health risks must be considered.

TL;DR: This study reports on the integration of a novel reconfigurable microstrip antenna capable of reconfiguring both its radiation pattern and frequency response onto a generic laptop computer structure.
Abstract: This study reports on the integration of a novel reconfigurable microstrip antenna capable of reconfiguring both its radiation pattern and frequency response onto a generic laptop computer structure. The purpose of such an exercise is to provide the relevant information necessary to integrate high performance antennas onto structures that can be used in ad hoc communication scenarios as well as other demanding applications. To pre-evaluate candidate antenna locations on the laptop chassis, an electromagnetic visibility study (EVS) is performed. Once integrated into candidate positions that have been analyzed by the EVS, the operation of the antenna on the host structure is measured and assessed with consideration to several realistic electromagnetic environments. The resulting performance and packaging issues are discussed. A formalized procedure for the integration of the antenna onto any host chassis using the EVS as a tool is also included.

TL;DR: This article examined teaching techniques, lessons learned, and student performance during the integration of laptops in teaching and learning psychology in the traditional classroom at the United States Military Academy at West Point and found that students were more likely to attempt using laptops in the classroom if they actually had a laptop.
Abstract: 10 All freshmen at the United States Military Academy at West Point now have laptop computers to use in class Several instructors for the General Psychology course that all freshmen take are currently incorporating classroom learning activities and strategies to leverage the technology tools available with laptop computers The purpose of the study reported here was to examine teaching techniques, lessons learned, and student performance during the integration of laptops in teaching and learning psychology in the traditional classroom The goals behind introducing the laptops were to enhance teaching practices and efficiency and positively influence student learning and attitudes toward psychology We initially attempted to integrate laptop technology into the classroom during our summer teacher training sessions We soon discovered that the returning faculty members participating in these training workshops were not very motivated to integrate the technology Many instructors felt uncomfortable teaching students who were actively pounding keyboards to take notes Additionally, many faculty members believed that students would engage in activities not related to the class Giving up this control in the classroom was not acceptable to some faculty One faculty member stated outright, “My students won’t be using those laptops in my classroom” Initial faculty attitudes had an adverse impact on our attempts to get students using laptops in the classroom Another critical limitation influencing faculty adoption of laptops was whether faculty members actually owned a laptop During our faculty training, we used loaner laptops, returning them before classes started We soon discovered that faculty members were much more likely to attempt using laptops in the classroom if they actually had a laptop Fortunately, we acquired four laptops for the four instructors who participated in this study Subsequently, when we issued laptops to the six new instructors on our faculty this year—the semester after this study was conducted—all six aggressively worked to integrate laptop technology into their classroom strategies The students provided another hurdle to laptop integration Because this was the first year that the academy had laptops in the classroom, the students also were quite dubious about the utility of this technology They definitely saw advantages to doing e-mail and instant messaging in class, but the advantage of using the laptop as a tool for learning was not evident at first Several students simply resorted to taking notes with paper and pencil, a closed laptop beside them What follows is an overview of our quasi-experimental1 study examining Miracle or

TL;DR: Internet Suspend/Resume is a thick-client approach to mobility in which hardware virtualization and file caching are the keys to rapid personalization of anonymous hardware for transient use.
Abstract: The term mobile computing typically evokes images of a laptop, handheld, or wearable computer. However, the plummeting cost of hardware suggests that pervasive computing infrastructure could minimize the need to carry such devices in the near future. Personal computing will be available anywhere on demand, like light at the flip of a switch. Only when a user starts to use a computer will it acquire unique customization and state. When the user finishes using the computer, this customization and state will disappear from it. Thus, a user could travel hands-free yet be confident of making productive use of slivers of free time anywhere. For this to be a compelling vision from a user's viewpoint, the customization and state acquisition process must be accurate and nearly instantaneous. For it to be a viable business model, the management and system administration costs of pervasive deployments of machines must be low. Internet Suspend/Resume is a thick-client approach to mobility in which hardware virtualization and file caching are the keys to rapid personalization of anonymous hardware for transient use.

TL;DR: The author’s experience in content development and instruction using the Tablet PC is discussed and the evolution of the pedagogy and lessons learned over an academic year are presented along with student feedback.
Abstract: Over the past decade, there has been a great deal of activity across disciplines attempting to incorporate computing into the classroom environment. The now near ubiquitous nature of multimedia enhanced classrooms is indicative of the perceived benefits of this technology. In terms of instruction, these enhanced classrooms have enabled faculty to replace or augment chalk/whiteboard lectures with a variety of new pedagogy. At the extreme end of the spectrum are wireless or tetherless classrooms where students each have their own mobile computing device. Using these devices (laptop or PDA), students can in real-time view and interact with lecture material that incorporates multimedia, web-based content and experiments. For example, under this scenario, an instructor could embed web-based simulations in his/her lecture that can be accessed to further illustrate the points 1 . After students have experimented with these simulations, the instructor can then query the students as to what was discovered and how these discoveries relate to the subject of the lecture. However, results to date indicate that instructors must commit significant time and effort to make effective use of inclass computer technology 2 3 . Studies have also shown an additional shortcoming of using laptops, namely that students can not effectively use keyboards for note-taking 3 . This is especially true for engineering courses where the material is often mathematically and graphically intensive. On the surface, pen-based entry enabled by Windows XP based Tablet PCs promises to address the shortcomings noted above. However, given their recent introduction (Q1 2003), there have been no studies to show their effectiveness in an academic environment. This paper discusses the author’s experience in content development and instruction using the Tablet PC. The evolution of the pedagogy and lessons learned over an academic year are presented along with student feedback. In addition, the co-author provides a student’s perspective in using the device both in and out of class.

28 Oct 2004TL;DR: This work proposes a set of technologies that can be integrated into recording devices to provide stronger, more accurately targeted privacy protections than other legal and technical measures now under consideration.
Abstract: The growing popularity of inexpensive, portable recording devices, such as cellular phone cameras and compact digital audio recorders, presents a significant new threat to privacy. We propose a set of technologies that can be integrated into recording devices to provide stronger, more accurately targeted privacy protections than other legal and technical measures now under consideration. Our design is based on an informed consent principle, which it supports by the use of novel devices and protocols that automate negotiations over consent and ensure appropriate safeguards on recorded data. We define the protocols needed for this purpose and establish their security. We also describe a working prototype implementation that safeguards audio recorded by laptop PCs in a wireless network.

TL;DR: Clicky as mentioned in this paper is a user-centric input system that allows a user with a single mouse and keyboard to control multiple computers and displays running standard operating systems in a smart-space environment.
Abstract: We present a user-centric input system that is useful for a variety of applications in ubiquitous computing environments. Users in these environments currently switch between different keyboards and mice, or other devices, to interact with all the devices present. Allowing users to select a personal input device for the space and use it to interact with all the devices in the space is a more natural approach. Associating a user with an input device also serves to distinguish between the different users in a space, and creates the notion of a user session that is useful for applications like authenticating user actions on shared public displays or logging a particular user’s activities. Clicky is our prototype implementation of this idea. It allows a user with a single mouse and keyboard to control multiple computers and displays running standard operating systems in a smart-space environment. It is designed to be a light-weight middleware tool that does not require modifications to the base operating system. Any input device in the room, such as the keyboard and mouse on a personal laptop or handheld computer, can be used as a user’s input device to interact with the space. Clicky allows users to configure a set of displays in the space into a large “virtual display” and use a single mouse pointer to move across it. It also allows multiple users with their own input devices to share a public display. In this paper, we describe the motivation for a user-centric input system, and describe the current status of the implementation.

16 Jun 2004TL;DR: This paper presents simple statistical techniques based on time series to dynamically compute the processor and I/O demands of multimedia applications and present techniques to dynamically vary the voltage settings and rotational speeds of mobile processors and disks, respectively.
Abstract: In this paper, we present a time series-based approach for managing power in mobile processors and disks that see multimedia workloads. Since multimedia applications impose soft real-time constraints, a key goal of our approach is to reduce energy consumption of multimedia applications without degrading performance. We present simple statistical techniques based on time series to dynamically compute the processor and I/O demands of multimedia applications and present techniques to dynamically vary the voltage settings and rotational speeds of mobile processors and disks, respectively. We implement our approaches in the Linux kernel running on a Sony Transmeta laptop and in a trace-driven simulator. Our experiments show that, compared to the traditional system-wide CPU voltage scaling approaches, our technique can achieve up to a 38.6% energy saving while delivering good performance to applications. Simulation results for our disk power management technique show a 20.3% reduction in energy consumption without any significant performance loss when compared to a traditional disk power management scheme.

TL;DR: The Liquid Crystals, Laptops and Life as mentioned in this paper is an excellent introduction to chemistry and physics that are necessary for understanding the basic science and technology embedded in the laptop and in life.
Abstract: Liquid Crystals, Laptops and Life connects the laptop computer with life itself via liquid crystals, the phases of matter essential to both. In the process it provides an integrated introduction to those parts of chemistry and physics that are necessary for understanding the basic science and technology embedded in the laptop and in life. This book can be understood by students with a good background in high school chemistry and physics; yet it can also serve as a primer for scientists who are not well versed in the areas covered. The first section of the book is devoted to discussion of basic concepts of chemistry and physics. The second section applies these concepts and extends them to three classes of materials that make the laptop possible: liquid crystals, polymers, and semiconductors. The first two classes of materials relate naturally to the molecules essential to life, thus providing an introduction to this area in an independent chapter. The third section focuses on the applied science and technology of semiconductors, digital devices, and computers, as well as liquid crystal displays. This section concludes by illustrating how these materials and technologies are combined in and make possible the laptop computer. The final section discusses applications of liquid crystals to the arts and to life. Each chapter rounds off with references to more advanced literature, exercises that test the reader's understanding, and open-ended questions that encourage the reader to explore the topics in greater depth.

TL;DR: The National Survey of Student Engagement (NSSE) as discussed by the authors showed that students who are more engaged in their studies tend to have greater learn-to-learn and accelerated deve l o pment and persist at higher education institutions.
Abstract: ABOUT CAMPUS / JULY–AUGUST 2004 THE USE OF TECHNOLOGY for instru c t i o n has been tried and decried as far back as we can trace formal learn i n g . Socrates pre d i c t e d that a new medium, the written wo rd , would “ c re a t e forgetfulness in the learn e rs ’ s o u l s , because they will not use their memori e s ; t h ey will trust to the external wri tten characters and not remember of themselve s ” ( S o c r a t e s , as cited in Plato, 360 B. C. , n . p. ) . T h o m a s Edison claimed that motion p i c t u res we re “destined to revolutionize our educational system”(p. E2) and quickly replace textbooks. Most re c e n t l y, i n n ova t i o n s in the Internet and pers o n a l computing technology have been heralded by countless claims of revo l u t i o n , f ro m the spirited charge that t e c h n o l ogy will cure the ills of bad teaching to fears of i s o l a t e d , mute students expecting “ e d u t a i n m e n t ” and plagi a rizing all their work from the Internet. C l e a r l y, neither of those extreme effects of c u rrent technologies has m a t e ri a l i z e d . But just as the written wo rd and mov i e s became standard in our society and transformed the way we live, so will the Internet and personal computing. We are in the midst of what has been called a slow revo l u t i o n .The ways in which we communicate and do business are different from how they we re a decade ago. Students also spend their time and energy on campus d i f f e rently than they did a decade ago. U n d e rs t a n d i n g these changes will allow us to shape our future as mu c h or more than the changes shape us. Student engagement is a promising approach for analyzing how technology changes the eve ry d ay activities of college students. Engagement, defined simply as the time and effort spent on activ i t i e s , has become an e s t a blished means of understanding the experi e n c e and quality of student l e a rning in higher educat i o n . It is measured by using s p e c i fic behav i o rs such as discussing class material or p a rticipating in cocurri c ular activ i t i e s . A number of studies in recent decades h ave shown that students who are more engaged e x p e rience greater learn i n g and accelerated deve l o pment and persist at higher r a t e s .The 725 colleges and u n ive rsities that curre n t l y p a rticipate in the annu a l National Survey of Student Engagement (NSSE) demonstrate the grow i n g acceptance of engagement as a way to think about collegiate quality. In the spring of 2002, I conducted a qualitative study that used student engagement as a lens thro u g h which to analyze the effects of technology on campus. The setting was a four-year private institution that had, t h ree ye a rs pri o r, instituted a laptop computer re q u i rement for undergraduate students.The study used focus NEW PATTERNS OF STUDENT ENGAGEMENT

TL;DR: In this paper, the authors propose to replace a server-class disk array with a larger array of mirrored laptop disks to exploit the latency tolerance and parallelism of typical server workloads to achieve significant energy savings.
Abstract: The disk array of a server-class system can account for a significant portion of the server’s total power budget. Similar observations for mobile (e.g. laptop) systems have led to the development of power management policies that spin down the hard disk when it is idle, but these policies do not transfer well to server-class disks. On the other hand, state-of-the-art laptop disks have response times and bandwidths within a factor of 2.5 of their server class cousins, and consume less than one sixth the energy. These ratios suggest the possibility of replacing a server-class disk array with a larger array of mirrored laptop disks. By spinning up a subset of the disks proportional to the current workload, we can exploit the latency tolerance and parallelism of typical server workloads to achieve significant energy savings, with equal or better peak bandwidth. Potential savings range from 50% to 80% of the total disk energy consumption.

TL;DR: In this paper, a laptop PC bag with adjustable legs is presented, which can be transformed from a normal standard laptop carrying case into a portable workstation for today's more versatile user and workplace.
Abstract: A laptop pc bag provides not only a standard laptop carrying case for carrying and protecting a laptop PC but also a desk. The height of the bag can be adjusted by extending the legs as far as desired, from approximately six inches to thirty-six inches, thereby providing the right height of the desk for the user. This allows users of all ages and sizes to take advantage of bag in its desk format, regardless of where they are. The legs ultimately provide the user more freedom with their laptop PC and will allow the user to perform the tasks at hand in an easier and more comfortable manner than previously possible. A considerably more versatile laptop bag is provided, one that can be transformed from a normal standard laptop carrying case into a portable workstation, for today's more versatile user and workplace.

01 Jul 2004TL;DR: The experimental platform demonstrated that COTS GPS units can be used for a real-time GPS-based spatial audio communication system, but with some limitations.
Abstract: As a first step in studying the application of the global positioning system (GPS) in a spatial audio communication system, an experimental platform was developed using commercial, off-the-shelf (COTS) GPS units: a Garmin Rino 120 (Rino) and a laptop. Software running on the laptop was developed to create a spatial-audio communication system based on GPS data and the two-way radio link on the Rino units. The audio communications were rendered spatially on headsets and perceptually tested for a number of users. The perceptual results and implementation issues are discussed in this paper. The experimental platform demonstrated that COTS GPS units can be used for a real-time GPS-based spatial audio communication system, but with some limitations.

TL;DR: In this paper, a personal integrated circuit (PIC) is provided that can be presented to a laptop computer, and the certificate is checked for validity by a server via a network, and if valid, the user is then permitted to log into the server.
Abstract: A security system and method is provided. In an embodiment, a personal integrated circuit (“PIC”), is provided that can be presented to a laptop computer. The PIC includes a digital certificate personal to an authorized user and is operable to automatically install the certificate on the laptop computer once presented into the computer and once the user enters a valid password respective to the PIC. At this point, the laptop presents the certificate to a server via a network, and the certificate is checked for validity. If valid, the user is then permitted to log into the server. Having logged into the server, the user can remain logged in even as the PIC is removed and presented to different computing devices that are also able to connect to the server via the network. Typically, the user is only able to access the server through the computing device to which the PIC is attached. The user is automatically logged out of the server after a predefined period of inactivity or according to such other criteria as may be desired.
