MISC Project(Cell Phone Contolled Car)

Posted: 08 Feb 2011 11:02 AM PST

I want to make a toy car in which a sound sensor will be installed. A phone will be there(in silent mode & auto ans mode) inserted the headphone pin. And that headphone wire will be connected to the sound sensor...
The function inside there will be like this:

1. When we are in call then if we press any button on phone then the other person on the line will get some sound like"BEEP...!!!":). And each one of the button has its own unique sound, I mean various quality of "BEEP...!!!":D... Now what I'm saying is the sound sensor will catch the unique sounds and distinguish between them and the circuit inside the toy car should contain a microprocessor who perform a special job for each one of that sound...:confused:...

2. The toy car should contain 2 small motors inside there installed with the back two wheels of the toy car. The motoring action, I mean which motor to off or which to of will be performed by microprocessor:confused:. The sound recognition will be like this:

i. Both 2 Motors will be on when the sound of pressing 2 will be sensed by the sound sensor.:confused:
ii. Left one is off and right one is on when the sound of pressing 4 will be sensed.:confused:
iii. Right one is off and left one is on when the sound of pressing 6 will be sensed.:confused:
iv. Both 2 Motors will be off when the sound of pressing 8 will be sensed by the sound sensor.:confused:...

Now the use of this project cum Robotics, I don't think I've to tell you again... Though I'm explaining to you...
1. I'll call to the phone installed inside the toy car using another phone.
2. The phone is in silent mode so no sound will appear in the headphone terminal, If we don't make that phone silent the music will interfere and system malfunction can occur.
3. The phone inside is in auto receive mode so the call will be received in a moment.
4. Now press 2 to move the toy car ahead, 4 to turn left, 6 to turn right, 8 to stop.

But I'm very confused with the microprocessor performance... How will the microprocessor work....???:confused:
Please anyone can help me with this project giving me the full schematic Circuit Diagram of the board inside? And pointing out all the parts what to connect and where to connect...with full specification of the parts or instrument used.... Please....!!!!!
Please send the required information to my email(ttipu.ahmed@gmail.com).... Please...!!!

European Online Recruitment Up 25 Percent Year-on-Year, Reports Monster Employment In

Posted: 08 Feb 2011 09:07 AM PST

January 2011 Index Highlights:

The Monster Employment Index Europe reported annual growth of 25 percent in January, the most rapid pace seen during the current economic cycle

Recruitment remained relatively active, with less seasonal slow-down than is typically seen for the month. However, Real estate was the only sector to see increased demand from December to January, driven by growth in Germany and France. Transport, post and logistics noted the greatest annual gain

Public sector opportunities continued to reduce, aligning with trends of reductions in government spending in many European countries

Online job demand for Managers edged down slightly on a monthly basis

Germany continued to lead all countries in annual growth; Italy eased following a high performing December

Summary Overview
Long term online recruitment levels improved again, with the annual growth rate accelerating from 22 percent in December to 25 percent in January.

The seasonal slow-down was mild, relative to what is typically seen at this time of year. Engineering and production, manufacturing, maintenance, repair recorded notably mild degrees of easing on the month. These sectors continue to be among the largest contributors to Europe's overall job market turnaround.

Public sector job opportunities hit the lowest level since May 2010, reflecting significant cuts in government spending across the continent. Following a sharp rise in growth in education, training and library in December relating to the start of a new semester, the sector reduced to normal levels in January although remained up year-on-year.

The Monster Employment Index Europe is a monthly analysis of millions of online job opportunities culled from a large, representative selection of corporate career sites and job boards across Europe, including Monster.

Monster Employment Index Europe results for the past 13 months are as follows:

Jan-11 Dec-10 Nov-10 Oct-10 Sep-10 Aug-10 Jul-10 Jun-10 May-10 Apr-10 Mar-10 Feb-10 Jan-10
116 122 122 122 117 115 115 114 112 108 104 101 93

"The long term picture continues to improve, with Europe's industrial production, together with a high performing market in Germany, creating the highest annual growth rate seen since the recession," commented Andrea Bertone, Vice President of Business Operations at Monster Europe. "However, the Index shows the impact of tighter government spending, with significant reductions in public sector opportunities. The months ahead will be key as we see the currently-growing private sector react to these cut-backs."

Real estate leads monthly online job demand
Online job demand increased in just one sector in January with real estate registering a one point (one percent) monthly increase. This was largely driven by Germany, together with small improvements in France and Poland. Year-on-year, the sector's recruitment levels are up 24 percent, with activity largely focused on commercial rather than residential property.

Engineering exhibited some easing on the month with a reduction of four points (three percent). However, the sector typically sees a decline at this time of year and the long-term trend continues to strengthen year-on-year, at 34 percent. This trend was mirrored in transport, post and logistics (up 60 percent year on year); production, manufacturing, maintenance and repair (up 55 percent year on year); IT (up 12 percent year on year) and research and development (up 44 percent year on year).

Financial services carried some recruitment momentum into the New Year. Accounting, audit, taxes edged down marginally by one point (one percent) on the month, buoyed by robust demand in UK and Germany. From an annual growth view, the sector is now up 11 percent in the Index. Meanwhile, banking, finance, insurance saw its annual growth improve to a five percent pace.

Education, training, library registered the steepest monthly decline among sectors in the January Index, down 23 points (11 percent). The sector has historically seen seasonal declines in January of similar degree; the sector's long-term trend stayed on track, as annual growth remained at 16 percent. General public sector opportunities reduced by six points (seven percent) this month, dropping the sector's 12-month trend into negative territory.

Online job demand exhibited positive growth across all occupations for the year
Each of the nine occupational groups monitored by the Index registered monthly declines in online job demand in January, although the annual trends were positive year-on-year across all groups.

Annual growth in demand for plant and machine operators, and assemblers accelerated to 67 percent in January, leading all occupational groups. This aligns with trends seen in the production, manufacturing, maintenance, repair sector; the group's largest employer.

Managers saw mild easing in online recruitment activity in January of two points (two percent), reflecting widely sustained demand for white collar professionals. Annual growth for the group improved to 17 percent.

Service and sales workers; and elementary occupations registered downshifts in long-term growth. Nonetheless, demand remains substantially higher than it was a year ago in both occupational groups.

Cambridge Wireless Discovering Start-Ups winner goes on to global success

Posted: 08 Feb 2011 02:47 AM PST

February 8th 2011 - Cambridge Temperature Concepts (CTC), one of the winners in the Cambridge Wireless Discovering Start-Ups competition at the end of last year, is one of six global finalists in the Qualcomm Ventures' QPrize™ competition to represent Europe; and has already picked up a prize of 100,000 euros in venture financing.

CTC, founded by a group of scientists from the University of Cambridge, has developed a non-invasive DuoFertility fertility monitor to help couples start their families. It uses a wireless patch that measures physiology 20,000 times a day and transmits the results for expert analysis and advice. In a study of 99 patients who qualified for IVF treatment for unexplained infertility, DuoFertility has already shown to be equally effective as IVF in achieving pregnancy.

The six Qprize finalists representing China, Europe, India, Israel, Korea and North America now proceed to the final round of competition at the prestigious DEMO Spring 2011 event in California, to compete for the Grand Prize of an additional US$150,000 in venture financing.

CTC's involvement in the Qualcomm competition came as a direct result of entering the Discovering Start-Ups competition run by Cambridge Wireless and supported by the East of England Development Agency (EEDA). "We were delighted to win the Discovering Start-Ups competition and it was one of the judges, Frederic Rombaut, Head of Qualcomm Ventures for Europe, who encouraged us to enter the QPrize," explained Dr. Shamus Husheer, CEO at Cambridge Temperature Concepts. "To be selected for the final from the whole of Europe is incredible for our CTC team and also reflects the strength of world leading research and innovation coming out of Cambridge."

"The future of our industry relies on entrepreneurs to take risks and do what others have not done before to turn innovative ideas into reality," said NagrajKashyap, vice president of Qualcomm Ventures. "This year, we expanded QPrize from four to six regions through the addition of Israel and Korea, and the level of creativity and vision from the finalists really exceeded our expectations. Congratulations to these companies on their impressive accomplishments in the competition."

"We are delighted that CTC continues to go from strength to strength and is gaining International recognition," said David Cleevely, chairman of Cambridge Wireless. "Discovering Start-Ups was designed to provide a platform for new technology businesses and many of the other finalists from last year's initiative have also benefited from taking part in addition to the recognition and prize money. We all wish Shamus and his team every success in the final and we hope that CTC's experience will encourage more entrepreneurs and new companies to enter Discovering Start-Ups 2011."

CTC along with the other winners of Discovering Start-Ups 2010 - Augmentra, MagicSolver, OXEMS (Oxford Electromagnetic Solutions) and PneumaCare - will also be presenting at the Innovation Hothouse during the Cambridge Wireless, Future of Wireless International Conference in June.
