APPLE – A Novel Approach for Direct Energy Weapon Control

ABSTRACT

Adaptive photonic based phase locked elements (APPLE) is Raytheon’s DARPA development initiative. The initiative is for development of a directed energy weapon that utilizes a beam combining technique for the achievement of high power. It will integrate the laser enabled weapon applications into unmanned aerial vehicles. The APPLE program is to enable all electronic combining of high-power laser engraver beams within an agile, conformal aperture-a practical approach to synthesizing high-power weapon laser engravers from low-power modules for applications such as laser radar, laser target designation, laser communications, and weapons grade lasers. The idea is to provide electro-optical systems with the same mission flexibility and performance that microwave phased arrays provide for RF applications such as radar and electronic warfare systems.

10 GB ETHERNET

ABSTRACT


Since its inception at Xerox Corporation in the early 1970s, Ethernet has been the dominant networking protocol. Of all current networking protocols, Ethernet has, by far, the highest number of installed ports and provides the greatest cost performance relative to Token Ring, Fiber Distributed Data Interface (FDDI), and ATM for desktop connectivity. Fast Ethernet, which increased Ethernet speed from 10 to 100 megabits per second (Mbps), provided a simple, cost-effective option for backbone and server connectivity.

10 Gigabit Ethernet builds on top of the Ethernet protocol, but increases speed tenfold over Fast Ethernet to 10000 Mbps, or 10 gigabit per second (Gbps). This protocol, which was standardized in august 2002, promises to be a dominant player in high-speed local area network backbones and server connectivity. Since10 Gigabit Ethernet significantly leverages on Ethernet, customers will be able to leverage their existing knowledge base to manage and maintain gigabit networks.

The purpose of this technology brief is to provide a technical overview of 10 Gigabit Ethernet. This paper discusses:

• The architecture of the Gigabit Ethernet protocol, including physical interfaces, 802.3x flow control, and media connectivity options
• The 10 Gigabit Ethernet standards effort and the timing for Gigabit Ethernet
• 10 Gigabit Ethernet topologies
• Migration strategies to 10 Gigabit Ethernet

TRACKING AND POSITIONING OF MOBILE PHONES

ABSTRACT


Mobile positioning technology has become an important area of research, for emergency as well as for commercial services. Mobile positioning in cellular networks will provide several services such as, locating stolen mobiles, emergency calls, different billing tariffs depending on where the call is originated, and methods to predict the user movement inside a region. The evolution to location-dependent services and applications in wireless systems continues to require the development of more accurate and reliable mobile positioning technologies.
The major challenge to accurate location estimation is in creating techniques that yield acceptable performance when the direct path from the transmitter to the receiver is intermittently blocked. This is the Non-Line-Of-Sight (NLOS) problem, and it is known to be a major source of error since it systematically causes mobile to appear farther away from the base station (BS) than it actually is, thereby increasing the positioning error. In this seminar, I present a simple method for mobile telephone tracking and positioning with high accuracy.
This presents the location of a mobile telephone by drawing a plurality of circles with the radii being the distances between a mobile telephone and a several base stations (it will be found using Time Of Arrival (TOA)) and the base stations at their centers, and using location tracking curves connecting the intersection points between each circle pair instead of the common chords defined by the circles. We use location tracking curves connecting the intersection points of the two circles which will be drawn by ordinary TOA method, instead of the common chord as in TDOA.
