Factors of Bluetooth Technology to Mitigate Interference with Wi-Fi

Bluetooth wireless technology (BT) operates in the unlicensed Industrial, Scientific, Medical (ISM) band in the 2.4GHz frequency range. It randomly uses 79 1Mhz wide channels ranging from 2.402MHz to 2.480MHz. Each channel is occupied for a maximum time slot of 625us. During this time the radio must change the operating frequency, receive or transmit data, and provide enough off time before switching to the next hop frequency. In reality, the time the radio is actually transmitting on a given channel is much less and is dependent on the amount of data being transmitted. WIFI WiFi or 802.11 b/g, also operates in the same ISM band as BT. Due to complicated modulation techniques, 802.11g channels are 20MHz wide while 802.11b channels are 22MHz wide. This means a common WiFi channel can occupy from 20 to 22 BT channels. COURTESY: HTTP://EN.WIKIPEDIA.ORG/ WIKI/IEEE_802.11B-1999 INTERFERENCE For an RF signal to be received by the radios receiver, the RF signal must contain enough energy to be detected by the receiver circuit. The minimum receive level is known as the receivers sensitivity. This is similar to the lowest whisper that a human ear can detect. What if there happens to be two signals present at the same time and both are greater than the receiver’s sensitivity? Which signal will the radio detect? One would think that it would not be able to correctly detect either signal. That would be true if both signals are close to the same power level. If one signal had a higher power level than the other signal by a specific amount, the radio would be able to detect the more powerful signal. This is similar to a human ear being able to clearly understand members at a dinner table while there are many others talking at tables that are further away. The minimum ratio of power level for two signals when a radio can correctly detect the desired signal is known as the carrier/interferer ratio, or C/I. This means that two RF signals can exist on the same frequency at the same time without causing interference if the ratio of their power levels meet the radios C/I specification.

Informe de Recaudación - Direccion General de Impuestos Internos

Los ingresos recaudados por la Dirección General de Impuestos Internos (DGII) durante el año 2010 alcanzaron un total de RD$183,764.5 millones, sobrepasando en RD$13,028.4 millones la recaudación efectiva del año 2009.1 (Ver Gráfica 1.1) Gráfica 1.1 Comparativo recaudación acumulada DGII Enero - diciembre; en millones de RD$ 192,313.1 155,671.2 Hidrocarburos 112-00 (TN) 183,764.5 19,211.1 151,525.0 Efectiva 2009 Estimada 2010 Efectiva 2010 Este crecimiento en la recaudación interna ha estado impulsado durante el 2010 principalmente por los impuestos que gravan el consumo de bienes y servicios o impuestos indirectos, los cuales presentaron un incremento de RD$12,238 millones respecto al 2009 (ver Gráfica 1.2). Dentro de este renglón, el mayor aumento lo presentó el Impuesto Selectivo Ad-Valorem sobre Hidrocarburos, con un crecimiento absoluto de RD$4,154.7 millones. Este comportamiento se explica en parte por el incremento en los precios internacionales del barril de petróleo. En segundo lugar se encuentra el ITBIS, el cual mostró un incremento de RD$3,083.1 millones.

Science Olympiad Robots
by olin4 0 Comments favorite 6 Viewed Download 0 Times

Okay, so what is a robot? Per definition of, the Holder of All Human Knowledge, a robot is: a mechanical device that can perform physical tasks. A robot may act under the direct control of a human (eg. the robotic arm of the space shuttle) or autonomously under the control of a pre-programmed computer. In the context of Science Olympiad and other small engineering competitions, we are looking at the first type, human control. There are plenty of opportunities to put autonomous features into a Science Olympiad robot, but if you are reading this for content, it is likely beyond your scope and unnecessary. Therefore, for the purposes of this text only, a robot will be defined as: A mechanical device, operated under the direct control of a human, that is engineered to perform a specific task or accomplish a goal. In this case, the goal is to compete in Science Olympiad's Robot Ramble event. And win. More on that later. I'm not smart enough to build a robot! Yes you are. Modern technology has developed to the point at which it permeates our lives. One side effect of this is that it is much easier to learn and try out than in years past. The hobby robotics market is only increasing, and there are a number of companies that specifically make products catered to robots and their builders. Full directions and kits are available to build or program small robots. In some cases, they're even premade, and all you have to do is mess with them. This is often the best way to go about learning.

Very old Ricoh camera and lenses to work with newer DSLR ... - Rqna

Asked by SixfootJames on 2012-10-24T11:49:33-04:00 I've been given an old bag of Ricoh camera and lenses and I find that it would be such a waste not to be able to use in some way all this again for something. Can you give me some suggestions as to how to use this kind of equipment with a newer camera like a Canon 600D? Archives Arts Questions and Answers Photography Questions and Answers Oct 24th, 2012 Archives Week 43, 2012 Archives October, 2012 Archives Tags Lens Dslr Old Lenses Best Answer Answered by John Cavan on 2012-10-24T23:11:20-04:00 Ricoh, historically, used the Pentax K-mount for their film SLR cameras, but with a slight and important modification: they added a pin that's used to indicate the aperture is in auto mode for shutter priority use. With some careful work, you can for use on K-mount bodies made by Pentax or Samsung or with a for Canon EOS digital and film variants. Nevertheless, if you have Ricoh K-mount lenses, that pin has to go. You can confirm if you have these based on this helpful bit of info from Wikipedia: The R-K mount is used on Rikenon P lenses, Ricoh bodies that include the letter 'P' in their model number, and some non-Ricoh lenses. Now, it's also possible that the Ricoh lenses are M42 screw-mount lenses also known, funny enough, as the Pentax mount when most film cameras had it and Pentax was the SLR king. If that is the case, and it's easy to tell by just looking for threads on the lens mount, then you can easily get...

Analyzing Design Tradeoffs in Large-scale Socio ... - Christoph Dorn

Emerging online collaboration platforms such as Wikipedia, Twitter, or Facebook provide the foundation for socio-technical systems where humans have become both content consumer and provider. Existing software engineering tools and techniques support the system engineer in designing and assessing the technical infrastructure. Little research, however, addresses the engineer’s need for understanding the overall socio-technical system behavior. The effect of fundamental design decisions becomes quickly unpredictable as multiple collaboration patterns become integrated into a single system. We propose the simulation of human and software elements at the collaboration level. We aim for detecting and evaluating undesirable system behavior such as users experiencing repeated update conflicts or software components becoming overloaded. To this end, this paper contributes (i) a language and (ii) methodology for specifying and simulating large-scale collaboration structures, (iii) example individual and aggregated pattern simulations, and (iv) evaluation of the overall approach. Keywords: Design Tools and Techniques, System Simulation, Collaboration Patterns, Large-scale Socio-Technical Systems
