The following specification particularly describes the nature of this invention and the manner in which it is to be performed:-

FIELD OF INVENTION:

The present invention relates to a Wireless converter device. In particular the present invention provides a device that facilitates the wireless transfer of data through serial communication. Said device is portable. It further facilitates the conversion without utilizing the external power source and eliminates the use of wired connections.

BACKGROUND OF INVENTION:

In data communication devices (DC), serial data communication occurs through means of serial communication (Ms). A serial means of communication (Ms) is a serial communication interface through which data transfers through communication devices (DC) in or out at a time. Means of serial communication (Ms) establishes the serial communication between the Data terminal equipment (DTE1) and data terminal equipment (DTE2). Either the data is sent or received during data communication. The concept of serial communication is simple. The serial means of communication (Ms) sends and receives data at a time. This is slower than parallel communication, which allows the transmission of entire data at once; however, it is simpler and can be used over longer distances. For example, the IEEE 488 specifications for parallel communication state that the cabling between equipment can be no more than 20 meters total, with no more than 2 meters between any two devices; in contrast to said parallel communication serial communication can extend as much as 1200 meters.

Communication through serial means of communication (Ms) occurs through; (1) Ground (G), (2) Transmitting unit (Tx), and (3) Receiving unit (Rx). Since serial communication is asynchronous, the serial means of communication (Ms) is able to transfer data on one such said transmission unit while receive data on another. And thus provides bi-directional data transfer between the communications devices (DC).

However, data transfer using conventional means of serial communication (Ms) requires installation of wires with each individual communication devices (DC) (as shown in Fig.3). This further creates a mess of the wire and also pertains to the connectivity issues. It requires complicated wire networks for the data transfer between Data terminal equipment (DTE1) and data transmitting equipment (DTE2). Moreover wired connections are ordinarily subject to breakdown and there by requires more maintenance. Also they do not provide the flexibility in data transfer between varied communication devices (DC); as it requires communication device (DC) with same baud rate. Also the process of wiring each communication device (DC) with the means of serial communication (Ms) becomes cumber some.

Further in order to overcome the connectivity issues and cumbersome handling of the wired connections; wireless data transfer module is used to transmit data (as shown in Fig 4a, 4b, 4 c, 4d). Wireless data transfer module is a short-range communication technology intended to replace the wire and cables connecting portable unit and maintaining high levels of security. However, it requires 2.5 V to 5V DC for its operation. Also it requires additional DC voltage power supply for its operation which again involves cumbersome processing involved for installation of DC power voltage supply. Said wireless data transfer module is also not user friendly and universal. It requires similar type of communication devices (DC) for transmission of data for the sending and the receiving of data between terminal equipment (DTE1) and data terminal equipment (DTE2). In case where Data terminal equipment (DTE1) and data terminal equipment (DTE2) is not from same supplier opening of said equipment to get DC supply require for wireless data transfer module results into violation of warranty and other such problems. Moreover, supplying wireless data transfer module voltage supply from said equipment alters the performance of the equipment thereby making it less efficient. In yet another mode of data transfer through wireless data transfer module an external power source such as adaptor is required. Adaptor requires additional power supply of 230 V/ 50 Hz as per the requirement of power supply. For which additional power plug adaptor is required, that is contradictory to the concept of eliminating cable requirement.

The present invention (A) uses the existing means of wired serial communication (Ms) wherein; Said means of serial communication (Ms) is provided within communication device (DC). Said means of serial communication (Ms) establishes the serial communication between the Data terminal equipment (DTE)

In furtherance the present invention (A) eliminates the need of wired connections between the communication devices for data transfer. Wherein it eliminates the need of any wired communication by providing a Data transfer module (DT). Said Data transfer module (DT) transmits the data and is provided for the wireless transmission of the data. Said data transfer module (DT) is connected with the serial communication driver (SC).Means of wireless communication (MWC) is provided for the wireless transmission of data between the communication devices (DC). Said Means of wireless communication (MWC) is connected to Means of Serial Communication (Ms) and voltage booster (VB). Said Means of wireless communication (MWC) comprises of:
? Serial communication driver (SC)
? Data transfer module (DT)

Wherein further;

Said serial communication driver (SC) facilitates the present invention (A) to function even at low power since it consumes substantially low power compared to conventional serial communication driver. Further said serial communication driver (SC) alternatively enables and disables data transfer in bidirectional mode between communication device (DC) i.e. it functions either in transmitting mode or receiving mode at a time. Thereby consumes less power. Said data transfer module (DT) is provided for the wireless communication between the plurality of communication devices. Said data transfer module (DT) comprises:
? Transmitting Unit (Tx)
? Receiving Unit (Rx)
? Ground (G)

Wherein said,

Transmitting unit (Tx) and receiving unit (Rx) connects the means of serial communication (Ms) and Means of wireless communication (MWC). Transmitting unit (Tx) and receiving unit (Rx) is connected to series resistor. Transmitting unit (Tx) carries the negative voltage supply Said data transfer module (DT) wirelessly transfers the data to the remote devices from the serial communication driver (SC).It further regulates the said transmitting Unit (Tx) and the Receiving Unit (Rx) of the serial communication driver (SC) and regulates the power consumption. Thereby the present invention (A) Utilizes substantially less amount power and is energy efficient and yet is effective in data transmission.

Said protecting means (Mp) is provided for the protection of the present invention (A) in case of any reverse voltage protection. Said protecting means (Mp) is connected in opposite polarity with the charging means (Mc) such that it conducts the negative voltage from the said transmitting unit (Tx) of device. The charging means (Mc) is connected to the protecting means (Mp) and ground; parallel to the means of serial communication (Ms). The negative voltage across said charging means (Mc) is transmitted as the input voltage to the said voltage booster (VB). Voltage booster (VB) is connected with the charging means (Mc). Said voltage booster (VB) is provided to convert the input negative voltage to the positive voltage. Said voltage booster (VB) boosts the voltage and provide the voltage in the range of 3 to 5 V with respect to ground (G) along with said charging means (Mc).

WORKING OF INVENTION:

The present invention (A) facilitates the wireless data transfer between varied communication devices (DC). Data transfer is either enabled or disabled depending upon whether the communication between communication devices (DC) is occurring or not. This is regulated by said serial communication driver (SC). It enables the said device (A) to function as per the user requirement.

Now, Referring to Fig. 1; during the process of data transmission;

1. where there is no data transfer occurring between the communication devices( shown by the black line as in Fig .1 );

Said transmitting Unit (Tx) carries negative voltage. Further, said transmitting unit (Tx) provides the input negative voltage to the charging means (Mc) through protecting means (Mp) The protecting means (Mp) allows only the said negative voltage to pass through it. On receiving negative voltage the charging means (Mc) gets charged. This builds up the voltage across the charging means (Mc) wherein, further said voltage across the charging means (Mc) is transferred to the Voltage Booster (VB). The negative supply from the transmitting unit (Tx) of the means of serial communication (Ms) is converted into a positive voltage supply by the voltage booster (VB). Voltage booster (VB) transfers Said positive voltage to the means of wireless communication (MWC) as input voltage. The serial communication driver (SC) converts the serial communication voltage level into Transistor Transistor Logic (TTL) voltage level and transfers it to the data transfer module (DT). The data transfer module (DT) receives the power source from said positive voltage input, thereby providing power source to means of wireless communication (MWC). Thus the present invention (A) eliminates the need of external power source by generating the power within itself.

2. where there is data transfer occurring between the communication devices (DC) ( shown by the black line as in Fig .1 );

For the wireless data transmission through present invention (A) said charging means (Mc) is charged by the negative voltage as described herein above in step 1. The charged charging means (Mc) transfers the voltage to the voltage booster (VB); wherein voltage booster builds up the positive voltage. Said positive voltage is the input to the means of wireless communication (MWC). Data is transferred between the means of serial communication (Ms) and the means of wireless communication (MWC). During the data transfer process, said charging means is discharged and it provides charge to said voltage booster (VB). Said charging means (Mc) gets charged again upon receipt of negative voltage from said transmitting unit (Tx) and thus the cycle continues.

COMPARISON OF THE PRESENT INVENTION WITH THE PRIOR ARTS:

Referring to Fig 3, Data transmission through conventional techniques between communication devices (DC) occurs through wired connections. As shown in Fig. 3, data terminal equipment (DTE1) comprises of plurality of means of serial communication (Ms). Each of the said means of serial communication (Ms) are connected separately to data terminal equipment (DTE2) by the means of several wired connections. This leads to connectivity issues between data terminal equipment (DTE) that ultimately leads to poor or failed data transmission; thereby, fails to provide efficient data transmission and connectivity. Further the use of several wired connections leads to cluttering of said connections, damages the wires, increases the maintenance, and leads to poor connectivity. Also wired connections are subjected to physical wear and tear; the wear and tear causes frequent breakdowns in the connection. The operation of transmission of data becomes cumbersome with the use of plurality of cables. Moreover, it fails to provide wireless data transmission.

Referring to Fig 4, wireless Data transmission through conventional techniques between data terminal equipment (DTE) occurs through data transfer module (DT). Here the data transfer module (DT) is connected to the data terminal equipment (DTE1) through means of serial communication (Ms).Also in an alternative arrangement said data transfer module (DT) is provided inside said data terminal equipment (DTE1). The data terminal equipment (DTE) is the master device that connects to plurality of Data terminal equipment (DTE2) through the data transfer module (DT).

Referring to Fig 4a, wireless Data transmission through conventional techniques between communication devices (DC) occurs through data transfer module (DT) of the master device. The data transfer module (DT) is connected to data terminal equipment (DTE2) through serial communication for the wireless transmission of data between said master device and other data terminal equipment (DTE) However, in the prior art said data terminal equipment (DTE2) is powered by an external power supply (Ps). Said power supply (Ps) is an 230V to 5 V wired adapter. In the absence of the external power supply the data transmission comes to a standstill. The prior art thereby consumes substantially more external power and yet is not efficient in data transmission. Also, with the use of wired external power supply, said data terminal equipment (DTE2) is fixed at a permanent place, losing mobility, hence not portable.

Referring to Fig 4b, wireless Data transmission through conventional techniques between communication devices (DC) occurs through data transfer module (DT) of the master device. The data transfer module (DT) is connected to data terminal equipment (DTE2) through serial communication for the wireless transmission of data between said master device and data terminal equipment (DTE). The data terminal equipment (DTE2) is connected to data transfer module (DT) through wired connector having plurality of pins for serial transmission of data. For serial data transmission through said technique as shown in Fig. 4b, data terminal equipment (DTE2) must have said wired connector having plurality of pins. Thus the data transmission is limited only between the data terminal equipment (DTE2) and data transfer module (DT) that has wire connector having plurality of pins as it derives power from plurality of pins Thus, it’s not universal.

Referring to Fig 4c, wireless Data transmission through conventional techniques between communication device (DC) occurs through data transfer module (DT) of the master device. The data transfer module (DT) is connected to data terminal equipment (DTE2) through serial communication for the wireless transmission of data between said master device and data terminal equipment (DTE) However, in the prior art said data transfer module (DT), is powered by a 2.5 to 5V line from the data terminal equipment (DTE2); For doing so the circuit of data terminal equipment (DTE2) has to be altered in order to take out a supply of 5V. By altering the circuit of the data terminal equipment (DTE2), it results in violating the warranty of a communication device supplier. Moreover, it also alters the performance characteristics of the data terminal equipment (DTE2) as data transfer module will consume power from existing power source of data terminal equipment (DTE2)

Now Referring to Fig, 2, Wireless Data transmission through the present invention between data terminal equipment (DTE1) and data terminal equipment (DTE2) occurs through data transfer module (DT). The data terminal equipment (DTE1) is connected to data terminal equipment (DTE2) through means of wireless communication (MWC). Thereby, eliminating requirement of wired connections for data transmission as compared to conventional techniques in Fig. 3. Also, eliminates the connectivity issues between the data processing devices providing wireless data transmission. The present data transfer module (DT) utilizes the negative voltage of the means of charging (Mc) as a power source; thereby eliminating the requirement of external power supply and provides continuous uninterrupted data transmission; unlike the conventional techniques in Fig. 4a and 4c. Moreover, present invention eliminates the need of wired connectors having plurality of pins for the transmission of data; as the data transmission occurs through data transfer module (DT); thereby wireless transmitting data to multiple data terminal equipment (DTE2). Therefore, universal as compared to conventional techniques in Fig. 4b.
