Thiruvarur Thiyagaraja swami temple

Thiruvarur is located 290 kms away from Chennai, the capital of Tamil Nadu and is positioned between Nagapattinam (24 kms) and Thanjavur (56 kms). This town is situated in the southeast of Tamil Nadu, The Arulmighu Shri Thiyagarajar temple located in Thiruvarur town has many distinctions. It has the largest chariot or temple car among the temples in Tamil Nadu. The enormous Kamalalayam and the golden calm water in the temple tank are the glory of the town.

The Arulmighu Thiyagaraja swamy temple in Thiruvarur is famous in many aspects. This is the most revered and glorified of all Attaveeratta temples of Lord Shiva. Inside this temple, there is an art gallery depicting the greatness of the judicious king Manuneethi Cholan. The striking features of this temple are the Arulmighu Shri Kamalamba shrine and the sacred temple tank containing a small temple in miniature in the middle of it. The Shri Kamalambal shrine is one of the seats of the great mother, the goddess Shakti. This holy town has the glory of being eulogized in the Thevaram. The ancient musical instruments the Panchamuga and the Pari Nadaswaram were made here and it is interesting to note that these ancient musical instruments are used till today in this town.

History

The actual history of Thiruvarur Periya Kovil (Thiyarajar Temple) goes back more than 30th Century BC. The chola kings just renovated the Thiyarajar temple and built few extra shrines inside the temples. The known foremost devotee Tirunavukkarasar on 7th Century CE itself has said in his pasurams that the real existence of this cultural heritage is unknown and the temple is in existence for many centuries.

According to history, the central temple in Tiruvarur was installed by Muchukanta Chola.^[2] Tiruvarur is also associated with another legendary king, Manuneedhi Cholan

Tiruvarur is mentioned in the works of Thirugnana Sambanthar and Tirunavukkarasar, the foremost Saivite saints of 7th century CE.^[3] Tirunavukkarasar mentions several Tiruvarur temple traditions, such as Marghazhi Aathirai Vizha, Panguni Uttirai Perunaal and Veedhivitakanin Veedhi Panni. The granite structure of the Tyagarajaswami temple was first constructed by Aditya Chola I in 9th century and revamped during the reign of Rajaraja Chola I. The temple was upgraded and rebuilt with stone by Rajendra Chola I.^[2] The royal patronage continued and the town flourished as a cultural centre during the rule of the Nayaks, Vijayanagar kings and Marathas. This temple is one of the biggest in the country and this has the biggest temple chariot in the world. The Arulmigu Thyagarajaswamy Car festival (offen stated as Tiruvarur Chariot festival) celebrated here in months of March -April attracts large crowds. Tiruvarur car is very famous one and it is called as 'Aalither' in Tamil meaning car like ocean.

Tiruvaur was part of the Thanjavur District until 1991 and Nagapattinam District until 1997. Tiruvarur was made the headquarters of Tiruvarur District when it was carved out of Nagapattinam in 1997. Thiruvarur car festival 2008 was celebrated very grandly. The people came from all the surrounding areas.

Continuation...

Wireless connectivity offers us immense freedom and convenience. It allows us to perform tedious tasks with a minimum of intervention, allows some of our devices to have dual functionality, and makes the vast array of cables we inevitably always leave in the office redundant. Bluetooth technology "will" change the assumptions we all have about our electronic devices.With the cables gone, the idea of having a particular gadget for a specific job will no longer be relevant. With many of the devices already available to consumers, this scenario grows closer to reality every day.

Safety-critical

Although the Bluetooth specification with a frequency-hopping scheme which does provide robustness, it is still a serious consideration for some applications. Bluetooth technology should not be used for safety-critical applications where data absolutely must get through, because there is always a possibility of a burst of interference stopping the link. Interference can come from a variety of sources: microwave ovens, thunderstorms, other communications systems. There are other safety-critical applications where an unreliable link may be acceptable.

Connection Times

There are two delays in setting up a Bluetooth link. First, it takes time to discover devices in the neighborhood. In device discovery, a device sends out inquiry packets, and receives responses from devices in the area, then reports these to the user. It can take ten seconds to find all the devices in an area, and even then you will only find those devices which are willing to report their presence. Some devices may not be set to scan for inquiries, in which case you will never find them!

A second delay occurs when you set up the connection itself. Again, this can take up to ten seconds.This lengthy connection time means that Bluetooth devices are unsuitable for systems where a fast response is needed, such as automatic toll collection on busy roads.

Power and Range

Power is a critical consideration for wireless devices. With the cable gone, the subject of batteries is brought into focus, and the inevitable questions arise concerning battery life, standby time, and physical dimensions. Keeping the power consumption low is an important consideration.

The range of battery life depends upon the product functionality. Power consumption is much higher when either transmitting or receiving, so the longer you expect your product to be in these states the shorter the battery life. Clever power management design, battery monitoring and use of the Bluetooth power saving modes will all contribute to reducing power consumption.

The Bluetooth specification defines three power classes for radio transmitters with an output power of 1 mW, 2.5 mW and 100 mW.The output power defines the range that the device is able to cover and thus the functionality of your product must be considered when deciding which power class to use.

Lonely

No one with me,
No one around me,
No one look at me,
No one get my happy,
No one share my sorrow,
No one even touch me,
I am in love.
So, I am in love.

Lonely I said myself,
Love is god and
He is with me!

My first english poem

Dream like a stream
Passes in fraction,
It makes a storm,
In our motivation.

Bluetooth - Introduction

Thanks to Bluetooth Application Developer’s Guide 

Communication between electronic devices can only be achieved when they also abide by a set of predetermined rules and standards—the Open Systems Interconnect (OSI) model for communications systems protocol stacks being the primary example, and the basis from which many others have evolved.

New technologies are now emerging that allows wireless communication. The IEEE 802.11b or Wi-Fi standard is becoming accepted as the choice for the networking community. IEEE 802.11b has a data throughput of up to 11 Mbps, which gives it viability against wired networks. This technology is expensive and therefore not compatible with price-conscious consumer products, but we have now been provided with the means to create wireless, low-power, cost-effective, unconscious and ad-hoc connectivity between our devices. Its name: Bluetooth.

Wired and Wireless

In the wired solution scenario that we are all accustomed to, all of the mobile devices are used in the singular—the interaction between them is always user initiated.

The alternative – In Bluetooth - The simple act of utilizing Bluetooth technology as cable replacement removes the problem of the actual physical connections and the unconscious and ad-hoc connection capability of the technology can allow communication between the devices with no user intervention at all (OK, after some software configuration and initial device setup!)

This fully wireless scenario can be achieved because of the master/slave nature of the Bluetooth technology. All devices are peers, identified by their own unique 48-bit address, and can be assigned as a master either by function or user intervention. A master can connect to up to seven slaves at the same time, forming a piconet—this “point-to-multipoint” feature is what sets Bluetooth apart from other wireless technologies.
