Machine Topologies

SR machines can offer a wide variety of aspect ratios and salient pole topologies. This means that each application is likely to be better suited to a specific SR topology. Therefore it is difficult to give an overview of which topology offers what advantage or disadvantage without resorting to sweeping statements. However, here goes.
Single-Phase Motor
These are the simplest SR motors with fewest connections between machine and electronics. The disadvantages lie in very high torque ripple and inability to start at all angular positions. Maybe attractive for very high speed applications, but starting problems may preclude their use.
Two-Phase Motor
Problems of starting compared with single phase machines can be overcome by stepping the air-gap, or providing asymmetry in the rotor poles. This machine may be of interest where the cost of winding connections is important, but again high torque ripple may be detrimental.
Three-Phase Motor
Offers simplest solution to starting and torque ripple without resorting to high numbers of phases. Hence has been the most popular topology in its 6/4 form. Alternative 3-phase machines with doubled-up pole numbers can offer a better solution for lower speed applications. But again watch-out for torque ripple especially in the voltage control single-pulse operating mode.
Four-Phase Motor
Maybe popular for reducing torque ripple further, but the large number of power devices and connections will probably limit four phase to a limited application field. Five- and six-phase motors can offer better torque ripple reduction compared with four-phase and three-phase.

Solar-powered bamboo radio could prove a design for life for Madagascar

Becky, 22, developed the concept after many visits to Madagascar, where her parents have spent the last 26 years working for charities.

The University of Plymouth student said: “Over two thirds of the population exist below the poverty line, earning around $1 per day. So I have been really motivated to develop a project that would use the education I have been lucky enough to enjoy, and the resources of the University, to provide opportunities for those not so lucky.

“The idea is that by using sustainable and naturally occurring resources in the construction of the radios, we can provide jobs and opportunities for people in Madagascar.”

After meeting with aid organisations on her most recent trip earlier this year, Becky found that they were very receptive to her proposed project, as radios could enable agencies to communicate with remote villages to provide both important health updates and also act as education channels.

So she worked on the designs, using sustainable materials, and found that with the plentiful supply of bamboo in certain areas of the country, the costs of production could be kept relatively low.

Becky said: “ is an amazing material - it has many of the properties of a hard wood but takes a fraction of the time to grow. And because of its natural structure, it produces a fantastic sonorous quality.

“If this takes off we could establish workshops in the country, provide good salaries, and put the means of production into their hands.”

Becky has produced two models - a desktop version and a portable one constructed from hand woven reeds - and the idea is to sell them both in Madagascar and also in England, where they will retail at a higher price to help provide the capital to fund further social enterprise projects.

Both models will be exhibited at the University of Plymouth Degree Show in June, and then again at New Designers in London in July. And the designs also helped Becky win the Social Enterprise Award at the University’s Business Ideas Challenge this week - with £250 and a comprehensive support package to go along with it.

Once she has graduated, Becky, from West Sussex, will be looking to establish BOO Enterprise, possibly with the support of the University’s Formation Zone business incubation unit.

And her design talents do not sSolar-powered bamboo radio could prove a design for life for Madagascartop at radios - she will also be showcasing a low tech refrigeration system that uses evaporation to cool food, and a parasol that provides shelter from the sun in the day but which powers up a solar-fuelled light for use at night.

Professor Roberto Fraquelli, of the School of Architecture, Design and Environment at the University, said: “This is another fantastic example of how our students are taking real issues and problems and using them as the inspiration for their designs

“Becky has a unique first hand insight into the complex situation in Madagascar and her vision is powerfully simple - to raise aspirations and the standards of living.”

Dell Streaks Into Tablet Scene

Dell (Nasdaq: DELL) on Tuesday announced that its upcoming Streak mobile device will be available in the United Kingdom in June, and in the U.S. later this summer.

The Streak -- Dell's 5-Inch Android-Based Tablet
The Streak -- Dell's 5-Inch Android-Based Tablet
The Streak, which runs on the Android mobile OS, is "a hybrid device that lies in the space between a smartphone and other larger tablets or netbooks," according to Dell executive Lionel Menchaca.

"The Dell Streak brings together a great Web browsing experience, multitasking capability, slick turn-by-turn navigation, and a great way to enjoy your photos, movies and music into a sleek device that's built for mobility," Menchaca said.

Despite the Streak's apparent similarities with the Apple (Nasdaq: AAPL) iPad, Dell officials downplayed such comparisons.

"I wouldn't position it against the iPad; while we do share some common features, the Streak also offers phone features," Dell spokesperson Matthew Parretta told TechNewsWorld. "The Streak's a data-centric device with voice capabilities that's designed to be an extremely small, portable, and still give the real Web experience you can't get on a three-inch-screen device."

Flexible OLED display is rollable

From Sony Corp. comes a highly flexible OLED display that can be rolled around a pencil and continue to operate.

The 4.1-inch diagonal display is 80-microns thick and offers 432 by 240 by RGB pixels resolution at 121 pixels per inch. It is an organic LED full color display driven by an organic thin-film transistor matrix.

The key to the display is the use of a peri-Xanthenoxanthene (PXX) derivative with 8x the current modulation of conventional OTFTs. This was achieved due to the development of integration technologies of OTFTs and OLEDs on an ultrathin 20µ thick flexible substrate together with soft organic insulators for all the insulators in the IC.

The panel is capable of reproducing moving images while being repeatedly rolled-up and stretched around a cylinder with a radius of 4-mm.

Sony has so far developed a prototype and said it would proceed with the development of a production process based on printing of organic materials dissolved in solvents. Sony said the displays are expected to yield thin, light-weight mobile devices with enhanced form-factor.

Sony's PXX derivative is stable under exposure to oxygen, moisture, light and heat and improves the current modulation by a factor of eight over conventional OTFTs based on pentacene. The roll-up capability is partly possible because the rigid driver IC chips are no longer required for the display.

The display has withstood more than 1000 cycles of repeatedly rolling-up and stretching the display without degradation in the display's ability to reproduce moving images, Sony said.

Line Follower

A line follower is an autonomous bot that can follow a specific colored line painted on a surface of different contrast, such as white on black.

To start with first of all I will be discussing a small concept of light. I believe you all know that the light that strikes any platform is reflected. The reflection and absorption coefficient of light depend upon material, color of platform and other factors. In simple words the black surface absorbs the light and the white surface reflects it, this is the basic concept behind making a line follower.

Line Follower

So the line follower has an emitter and a reflector. The reflector receives the light and generates a voltage proportional to the intensity of the light, if this voltage is above a threshold it means SIGNAL=1 (logic one) else SIGNAL= 0 (logic zero).

Let’s take up an example where we have to move our bOt on black surface having white line. Suppose I have two Infra Red (IR) sensor pairs that are on different halves of a bOt with respect to geometrical central axis of the bOt. The sensors are placed in such a way that the white line lies in between both the sensors when the bOt is placed on the white track painted on black surface to move. Now if the white line is between both the sensors while moving forward both the sensors will be on black surface and the detectors/receivers will receive less amount of light since black absorbs light and hence signal provided by both the infra-red receivers will be low.

Line Follower explanation

Now if the heading/direction of the white line changes one of the sensors will move in the region of white line and will start giving output signal as high. This information can be used to ‘turn’ the bOt and orient itself in the right direction. For example in the above figure if the bot is located in position 1, then bOt will move forward and if the bOt is in position 2 it will have to turn left .

Let’s move on and discuss everything step by step in detail. We will be discussing the making of line follower under three heads:

1.) Chassis of robot { those familiar can skip this section}

2.) Electronics/Hardware Designing

3.) Programming/Software Designing

CHASSIS OF ROBOT

1.) Base of robot: The base or the material of the platform of robot can be made with any easily available material like switch board, wood, acrylic sheet or steel sheet. As our robot will be very light, you don’t have to think a lot on strength and other such factors. We will just recommend you to make a small size and light weight bOt. Here we are using, steel base:

Chassis of line follower

2.) Motors and Driving Mechanism:

· We will need a set of two motors that have same rpm (revolution per minute).

· We will be using differential drive for maneuvering our bOt i.e. we will have three wheels for our bOt, the front two will be powered and the rear will be free wheel.

· When the bot is moving straight both the motors should have equal speed.

· For turning, one of the motor is switched off. If we switch off the left motor, the bot will turn left and vice versa.

Line Follower motor

· You can choose a motor of rpm around 100 and a torque of 1kg-cm

MotorLine  follower bOt

3.) Coupling wheels & clamping motors: - For clamping the motors you can use pipe clamps or make right angled clamps. The right angle clamps ensure more rigidness. To couple the motor ensure that the shaft of motor and hole of wheel have equal diameter (if you can’t find one check the tutorial on wheels).

Line follower clampingLine  follower clamping 2

ELECTRONICS

Line follower flowchart

This is a flow chart that explains the working of the bOt in sequence:-

The Infra Red sensors are used to interact with the environment. The emitter sends a ray which is received by detector in the form of voltage and it then amplified by amplifier since the signals are weak (more on this later). Below are the circuit diagrams of Infra-red LED emitter and receiver.

Line  follower IR sensorLine follower IR receiver

Op-Amplifier (LM324)

If the rays received by the IR- LED receiver are above a particular threshold then an amplified signal is generated by the amplifier (LM324). Note that the sensors cannot directly send a signal to the microcontroller as the signal voltage generated by them is too low and even when sensors are on white surface signal generated by them will interpreted low by the microcontroller.

Line Follower LM324

Microcontroller (AT89S52)

The microcontroller receives the signal and responds accordingly. It takes the decision based on input signal received by both the receiver LEDs. It will give command to motors through H-bridge to move forward, or take a left turn or a right turn.

H-bridge (L293B)

The microcontroller sends a signal to the H-bride that acts as a switch. If the signal received by the H-bridge is high it will rotate the motor or else it won’t do so. Note that microcontroller only sends a signal to a switch which gives the voltage required by the motor to rotate. Here we are using L293B which can be used to control two motors.

Pin connections for H-bridge:

ü En1 & En2 are given logic 1 from microcontroller or give 5V from outside and are used to activate/deactivate one ‘half’ of the H-bridge.

ü V is the voltage that you want to supply to the motor(s) : 9 or 12V

ü Vcc is the logic 1 or 5V

Line Follower motor circuit diagram

The complete circuit diagram with all the integrated circuits required for making a line follower is shown below:-

Line follower circuit

Here we are using pins P1.0 and P1.4 for taking inputs from the IR sensors after being amplified by LM324.

P1.0 – Input from left sensor

P1.4 – Input from right sensor

There are six outputs from AT89S52 microcontroller to the H-bridge.

Pins P0.0 and P0.4 are connected to enable pins of the H-bridge. We can use them to deactivate/active the two halves of H-bridge i.e. if pins are set to logic 1 the corresponding half of the H-bridge will be activated.

P0.1 – will drive the left motor in forward direction

P0.2 – will drive the left motor in reverse direction

P0.3 – will drive the right motor in forward direction

P0.5 – will drive the right motor in reverse direction

Programming

Below is the code in C for the line follower.

Satellite radio

We all have our favorite radio stations that we preset into our car radios, flipping between them as we drive to and from work, on errands and around town. But when travel too far away from the source station, the signal breaks up and fades into static. Most radio signals can only travel about 30 or 40 miles from their source. On long trips that find you passing through different cities, you might have to change radio stations every hour or so as the signals fade in and out.

Now, imagine a radio station that can broadcast its signal from more than 22,000 miles (35,000 kill) away and then come through on your car radio with complete clarity without ever having to change the radio station.

Satellite Radio or Digital Audio Radio Service (DARS) is a subscriber based radio service that is broadcast directly from satellites. Subscribers will be able to receive up to100 radio channels featuring Compact Disk digital quality music, news, weather, sports. talk radio and other entertainment channels.

Satellite radio is an idea nearly 10 years in the making. In 1992, the U.S. Federal Communications Commission (FCC) allocated a spectrum in the "S" band (2.3 GHz) for nationwide broadcasting of satellite-based Digital Audio Radio Service (DARS).. In 1997. the FCC awarded 8-year radio broadcast licenses to two companies, Sirius Satellite Radio former (CD Radio) and XM Satellite Radio (former American Mobile Radio). Both companies have been working aggressively to be prepared to offer their radio services to the public by the end of 2000. It is expected that automotive radios would be the largest application of Satellite Radio.

The satellite era began in September 2001 when XM launched in selected markets. followed by full nationwide service in November. Sirius lagged slightly, with a gradual rollout beginning _n February, including a quiet launch in the Bay Area on June 15. The nationwide launch comes July 1.

SATRACK

According to the dictionary guidance is the ‘process of guiding the path of an object towards a given point, which in general may be moving’. The process of guidance is based on the position and velocity if the target relative to the guided object. The present day ballistic missiles are all guided using the global positioning system or GPS.GPS uses satellites as instruments for sending signals to the missile during flight and to guide it to the target. SATRACK is a system that was developed to provide an evaluation methodology for the guidance system of the ballistic missiles. This was developed as a comprehensive test and evaluation program to validate the integrated weapons system design for nuclear powered submarines launched ballistic missiles.this is based on the tracking signals received at the missile from the GPS satellites. SATRACK has the ability to receive record, rebroadcast and track the satellite signals. SATRACK facility also has the great advantage that the whole data obtained from the test flights can be used to obtain a guidance error model. The recorded data along with the simulation data from the models can produce a comprehensive guidance error model. This will result in the solution that is the best flight path for the missile.
The signals for the GPS satellite navigation are two L-band frequency signals. They can be called L1 and L2.L1 is at 1575.42 MHz and L2 at 1227.60 MHz.The modulations used for these GPS signals are

Narrow band clear/acquisition code with 2MHz bandwidth.
Wide band encrypted P code with 20MHz bandwidth.

L1 is modulated using the narrow band C/A code only. This signal will give an accuracy of close to a 100m only. L2 is modulated using the P code. This code gives a higher accuracy close to 10m that is why they are encrypted. The parameters that a GPS signal carries are latitude, longitude, altitude and time. The modulations applied to each frequency provide the basis for epoch measurements used to determine the distances to each satellite. Tracking of the dual frequency GPS signals provides a way to correct measurements from the effect of refraction through the ionosphere. An alternate frequency L3 at 1381.05MHz was also used to compensate for the ionospheric effects.
