TL;DR: The time-indexed SMDP model (TISMDP) that is needed to handle the non-exponential user request interarrival times and shows large savings for all three devices when using the algorithm based on this model.
Abstract: Portable systems require long battery lifetime while still delivering high performance. Dynamic power management (DPM) policies trade off the performance for the power consumption at the system level in portable devices. In this work we present the time-indexed SMDP model (TISMDP) that we use to derive optimal policy for DPM in portable systems. TISMDP model is needed to handle the non-exponential user request interarrival times we observed in practice. We use our policy to control power consumption on three different devices: the SmartBadge portable device [18], the Sony Vaio laptop hard disk and WLAN card. Simulation results show large savings for all three devices when using our algorithm. In addition, we measured the power consumption and performance of our algorithm and compared it with other DPM algorithms for laptop hard disk and WLAN card. The algorithm based on our TISMDP model has 1.7 times less power consumption as compared to the default Windows timeout policy for the hard disk and three times less power consumption as compared to the default algorithm for the WLAN card.

TL;DR: In this paper, a method and system for remotely storing data on a server through a wireless connection instead of storing data locally in a consumer device, as well as devices for use with the system and system.
Abstract: A method and system for remotely storing data on a server through a wireless connection instead of storing data locally in a consumer device, as well as devices for use with the method and system. More particularly, a video camera, still camera, laptop computer, or other consumer device which normally stores data in local memory such as film, disk, random access memory, memory sticks, or other forms of storage would transmit the data to a remote server through a wireless connection. The data would be saved on the remote server for subsequent retrieval through, for example, the Internet or a wireless connection to the server. In addition, data not originating from the user device could be downloaded to the consumer device. The data to be retrieved can be specified by the user, or sent to the user according to a user profile stored on the server.

TL;DR: Wearable PCs are finding plenty of users in the commercial world, and can handle off-the-shelf applications, such as database management and word processing, written for Windows or Linux operating systems.
Abstract: Concentrating the computational power of a multimedia desktop or laptop computer into a central processing unit only slightly larger than a hand-held organizer, wearable PCs are finding plenty of users in the commercial world. What wearable computers have to offer is job-critical information to people whose hands must be free for other work. Assembly line workers, for example, can access a database and look at drawings of what's being worked on and see step-by-step instructions for putting it together. These are shown on a small color display that hangs before a worker's eye, supported there by a head-mounted boom. The rest of the system-its central processing unit (CPU), which includes a microprocessor, RAM, and hard drive-is worn in a belt around the waist. The display is a small liquid-crystal chip, whose image is picked up by a silvered mirror, or transmitted through a prism, and reflected or redirected into the user's eye. The display is held at the end of a toothbrush-sized boom, supported by a headboard, say, or by a larger eye-covering mirror or prism arrangement. Thanks to magnifying optics and despite the closeness of the image to the eye, the viewer has the illusion of reading a normal-sized desktop screen at the usual arm's length viewing distance. Commands are either keyed into a small keyboard worn on the wrist or spoken into a microphone. A video camera is an option, and the computers have standard I/O ports for adding peripherals. In addition, the machines can handle off-the-shelf applications, such as database management and word processing, written for Windows or Linux operating systems. Just what is displayed varies, of course, depending upon the imagination of the system designer and the application. The computers are not cheap, ranging from US $5000 to $10000. They may be worth it, though, for what they can add to a person's job effectiveness.

TL;DR: One of the key design goals was to eliminate virtually all latency variation in low sample rate inputs like those from gestural input devices.
Abstract: Standard laptop computers are now capable of sizeable quantities of sound synthesis and sound processing, but low-latency, high quality, multichannel audio I/O has not been possible without a cumbersome external card cage. CNMAT has developed a solution using the ubiquitous 100BaseT Ethernet that supports up to 10 channels of 24-bit audio, 64 channels of sample-synchronous control-rate gesture data, and 4 precisely time-stamped MIDI I/O streams. Latency measurements show that we can get signals into and back out of Max/MSP in under 7 milliseconds. The central component in the device is a field programmable gate array (FPGA). In addition to providing a variety of computer interface capabilities, the device can function as a cross-coder for a variety of protocols including GMICS. This paper outlines the motivation, design, and implementation of the connectivity processor. 1. Context and Prior Work Hardware development for computer music performance systems has followed the standard pattern of technology evolution passing through the first two phases of design focus, function and price, to the final phase: usability. We have identified size and connectivity as primary usability issues for computer music performance systems. Laptop computers have recently become available with fast signal processing capabilities at a moderate cost and although their size makes them very attractive for musical performance, their constrained expansion capabilities limit connectivity. Currently there are no commercially available, low-latency, high-reliability, compact, multi-channel audio solutions for laptop computers. Furthermore the architecture of current laptops and most computers makes it impossible to synchronize acquired gestural data and sound I/O to satisfy the low latency/jitter needed for satisfactory reactive performance systems: 10±1ms (Freed, et al., 1997). The 10 ms latency criterion is not difficult to meet, but a maximum latency variation of ±1ms is difficult to achieve, especially when the stimulus gesture is represented as a MIDI event or a low rate signal from a nonsample-synchronous input source like a data acquisition card rather than a sample-synchronized audio input signal. The only computers with the requisite unified clock management and operating systems support for such tight synchronization are from Silicon Graphics. Unfortunately, even the smallest configurations of their machines, the O2 and Octane are too large and expensive for most performing musicians. One of our key design goals was to eliminate virtually all latency variation in low sample rate inputs like those from gestural input devices.

TL;DR: In this paper, the authors proposed the concept of modular flat panel displays (LCD and flat screen displays), which are made from multiple (two or more) modular pieces to form a single larger screen of various sizes.
Abstract: LCD and flat screen displays are made as one piece, with active TFT screens being more expensive than passive screens. They are as stand-alone monitors (single or cluster), or mounted (single) with desktop computers or used on laptop computer monitors (single). Some of the stand-alone single LCD monitors can be rotated. Some LCD monitors can be detached but are reattached on same axis and position. The laptop computers include notebooks, sub-notebooks and smaller units. The proposal is two fold. The LCD or flat panel screen monitor is made from multiple (two or more) modular pieces to form a single larger screen of various sizes. Both standard LCD and these modular LCD screens as single monitors and/or as a cluster of multiple screens, on laptop computers or when attached to desktop computers, have the special feature of being detached and reattached or shifted (without being detached) to a different axis and/or position relative to the original position. The use of two or more smaller sizes (including undamaged smaller pieces cut from larger damaged pieces) is to form a single larger modular LCD screen. The special feature of the LCD (standard and modular) screen being detached and reattached or shifted (without being detached) to a different axis and/or position relative to the original position is unique for laptop computers and when the LCD monitor is attached to the desktop computer. The cluster concept of multiple LCD monitors (standard and modular) on a single laptop is unique to the laptop computers which currently has only a single LCD monitor for each laptop. LCD monitors include any other type of flat panel display.
