Description
TELEPHONE DEVICE HAVING A DETACHABLE INpUT-RADING MODULE
The invention relates to a telephone device, and in particular to a telephone device having a detachable inputreading module.
Since telephones are widely used in houses, offices and other areas, a large variety of functions and services for the telephones have been implemented over the years.
For example, telephone-shopping, banking by telephone from home, etc. As such applications have increased, a greater and greater amount of data is being acquired through the telephones. However, conventional telephones only provide some simple functions, such as dialing, re-dialing, memory dialing, etc.. Therefore, the conventional telephones can not process a great amount of data or display received data, thereby limiting attainment of maximum efficiency of convenient services.
In order to completely provide various services, an intelligent telephone has been disclosed. The intelligent telephone meets the specifications of the Bellcore ADSI (Analog Display Services Interface). In addition to having a handset and push-button pad, there is a keyboard or touch screen acting as an input device. Furthermore, the intelligent telephone has a liquid-crystal display (LCD) for data output. The liquid-crystal display is rotatable to facilitate viewing displayed messages by users.
According to the specifications enacted by the Bellcore
ADSI, the intelligent telephone must be able to communicate with the outside and provide information services, such as a caller ID, electronic shopping, electronic booking, stock market information, etc. which greatly enhance telephone functions.
Even though the conventional intelligent telephone can attain the above-mentioned functions which a conventional telephone can not provide, it still has several disadvantages. Basically, a great amount of data can be stored in the intelligent telephone, but they are limited to just use in the telephone, such that the provided functions can not be used flexibly. Moreover, the various data restored in the telephone also can not be further processed resulting in restricted data communication.
Those mentioned above are the disadvantages of the conventional intelligent telephone.
In view of the above, the object of the invention is to provide a telephone device having a detachable inputreading module which not only has all the functions as provided by the conventional intelligent telephone, but also efficiently transmits, restores and manages acquired data, thereby attaining maximum efficiency.
For these purposes, the invention provides a telephone device having a detachable input-reading module, basically which includes a detachable input-reading module, a telephone having a receptacle and a data exchange interface. The input-reading module is a device which can operate alone, and has an input device for data input and a screen for information display. The receptacle can be a concavity of a size approximately the same as that of the input-reading module, on which the input-reading module can be placed. The telephone and input-reading module which can restore a great amount of data are connected to each other in series via the data exchange interface. When the input-reading module is placed in the receptacle, a communication path between the telephone and input-reading module is established to transmit data. Basically, the data exchange interface can be implemented by use of communication circuits inside the telephone and inputreading module. Therefore, when the input-reading module is installed in the telephone, users can process the control to attain all the functions as provided by a general intelligent telephone. In addition, the data can be read from the telephone to make the data storage, exchange and management more flexible.
The present invention will become more fully understood from the detailed description given hereinbelow and the accompanying drawings, which are provided for illustration of a preferred embodiment only and should not be construed as limiting the scope of the present invention, and wherein:

PREFERRED EMBODIMENT
In comparison with the prior art, a telephone having a detachable input-reading module according to the invention is characterized in that the input-reading module is detachable and its functions are similar to those of a personal digital assistant (PDA). When the input-reading module is placed in a concavity which is located on the telephone, a communication path between the input-reading module and telephone is established, thereby indicating required instructions, such as telephone shopping, electronic booking, stock market information checking, data storage into a memory, etc., by an input device or touch screen on the input-reading module. When the communication path is broken, the input-reading module containing the stored data can carry out other processes, such as storing and analyzing. The detailed description of an embodiment will be described hereinafter.
Figs. 1 and 2 are outline views showing a telephone and an input-reading module which are separated from each other, and a telephone and an input-reading module which are coupled to each other, respectively. Now, referring to
Fig. 1, a telephone 10 and an input-reading module 20 are separated from each other, wherein the telephone 10 has a push-button pad 12 for dialing, a handset 16 and a concavity 14 having a size approximately the same as that of the input-reading module 20, on which the input-reading module 20 can be placed, wherein there is a connector 144 located on the bottom of the concavity, by which a physical layer for communication is established between the telephone 10 and input-reading module. Moreover, there are a liquid-crystal display 22 and an input button 24 on the input-reading module 20, and a connector 244 corresponding to the connector 144 on the bottom of the input-reading module 20. The liquid-crystal display 22 may have a touch screen function as another type of input device. In Fig.
1, since the input-reading module 20 is not placed in the concavity 14, a communication path between the telephone 10 and input-reading module 20 can not be is established. At this point, the input-reading module 20 may function as a general PDA and data restored in it can be used for other purposes.
In the coupled state as shown in Fig. 2, the inputreading module 20 is placed in the concavity 14 of the telephone 10. After that, a communication path between the telephone 10 and input-reading module 20 is established by means of the connection between the connector 244 of the input-reading module 20 and the connector 144 of the telephone 10. At this time, the operation can be processed by use of the input button 24 of the input-reading module 20 or use of the touch screen function of the liquidcrystal display 22. In the coupled state shown in Fig. 2, all functions like those of a conventional intelligent telephone are provided. Therefore, the telephone device according to an embodiment of the invention not only attains the functions as provided by a conventional intelligent telephone, but also the input-reading module can be used singly, such that users can not be limited to obtaining various services just from the telephone.
Meanwhile, the data is portable to facilitate information management.
Referring to Fig. 3, a block diagram illustrates a the telephone device having a detachable input-reading module according to an embodiment of the invention. The telephone device includes a telephone 10, input-reading module 20 and data exchange interface 30, wherein the telephone 10 consists of a microprocessor 100, telephone interface 102,
ROM 104, RAM 106, digital signal processing (DSP) module 108 and other related telephone control circuits, such as a dialing circuit and communication circuit. The inputreading module 20 includes a microprocessor 200, RAM 202,
ROM 204, liquid-crystal display 22, and an input button 24.
The data exchange interface 30 between the telephone 10 and input-reading module 20 comprises a communication IC 300 in addition to the telephone 10 and a communication IC 302, wherein the ICs 300 and 302 are controlled by the microprocessors 100 and 200 to is established a communication path between them. As for installing positions, the communication IC 300 can be disposed inside the telephone 10, and even in the microprocessor 100.
Similarly, The communication IC 302 can be disposed inside the input-reading module 20, and even in the microprocessor 200. Both of them (IC 300 and IC 302) can provide the required communication functions.
The telephone device can process data exchange with external telephone lines via the telephone interface 102 together with the DSP 108, such as processing an incoming call and outgoing call. The microprocessor 100 functioning as a control center reads data restored in the ROM 104 and then stores the acquired data in the RAM 106. At this time, when the telephone 10 is connected to the inputreading module 20 through the data exchange interface 30, the acquired information can be transmitted in the inputreading module 20 via the communication between the microprocessor 100 and microprocessor 200. At this point, the microprocessor 200 in the input-reading module 20 can process the required control based on the programs read from the ROM 204 and store the data transmitted from the telephone 10 in the RAM 202. On the other hand, the data can be transmitted from the input-reading module 20 to the telephone 10. For example, a telephone book in the form of a data library can be established by means of functions in the input-reading module 20 that are similar to those of a
PDA. When the telephone 10 and input-reading module 20 are connected to each other, the telephone numbers stored in the telephone book by the input-reading module 20 are transmitted to the telephone 10. Then, the users can utilize this information for operations, such as autodialing. Therefore, in an embodiment of the invention, the data inside the telephone device can be used efficiently by means of the data exchange between the telephone 10 and input-reading module 20.
As shown in Fig. 3, the data exchange between the telephone 10 and input-reading module 20 is performed via the data exchange interface 30. This is a key point of the invention. Therefore, the principle of the data exchange interface will be described hereinafter.
Generally, communication approaches are classified as a wired communication or a wireless communication. In wired communication, wires act as a medium between a transmitter and receiver. However, in wireless communication, communications take place by electromagnetic radiation, such as radio, infrared, without being conducted by any wires. There are two types of wired communication.
One is a parallel communication; the other is a serial communication. Since serial communication conserves wire utilization, an asynchronous serial communication is adopted in an embodiment for description. However, the same principle can also be applied to the parallel communication. That is, the invention can be performed by use of the parallel communication.
The functions of a general asynchronous serial communication interface can be performed by universal asynchronous receiver/transmitter (UART), wherein the data format and transmission rate are controlled by a microprocessor. The most commonly used series interface, a
RS-232 interface, is used as an interface standard in an embodiment. Generally, the RS-232 interface is a connector having 25 pins, wherein each pin of the connector is identified with a different function. Hence, the communications between two different interface connectors can be is established based on the identified functions of their pins.
Therefore, if the RS-232 interface standard is employed as a communication protocol in an embodiment, communication ICs 300 and 302 (UART chips) shown in Fig. 3 are controlled by microprocessors 100 and 200, respectively. Meanwhile, connectors 144 and 244 shown in
Fig. 1 are D-shaped connectors each having 25 pins.
Therefore, after the telephone 10 and input reading module 20 are connected to each other via connectors 144 and 244, data transmission can be processed via the UART chips under the control of the microprocessors 100 and 200. Since the distance for connection between the telephone 10 and input reading module 20 is very short in an embodiment, there is no need to completely use all the defined signal lines of the RS-232. In this embodiment, only 3 signal lines, a
RxD, TxD and signal ground (SGND), are used to process data exchange by using TTL level signals.
Furthermore, the data exchange can also be performed by use of a wireless communication approach, such as a currently widely used infrared Data Association (IrDA) interface. The communication distance which the IrDa interface can operate is about 1 m, and even can reach 3 m, wherein the wavelength of infrared is in a range of 850-900 nm. The advantages of using the IrDA interface are as follows: (1) no wire connection is needed; (2) the infrared communication has highly noise-resistant; (3) since an electrical isolation state exits between the receiver and transmitter and no electromagnetic wave is created during infrared transmission, thus electromagnetic interfere can be avoided. In an embodiment, if the IrDA interface is used for communication, IrDa chips can be used to function as the communication ICs 300 and 302 in
Fig. 3. At this time, the communication is processed without any wire connection between the connectors. The transmission rates of the above-mentioned interfaces are all in a range of 9.6-115.2 Kbps which meets the requirement of the general communication. Therefore, in the invention, just one communication interface used for data exchange is no limitation. That is, the data exchange interface 30 can be the wired RS-232 interface or wireless
IrDA interface. In addition, the data exchange interface 30 can consist of a wired RS-232 interface and a wireless
IrDA interface, wherein just one of them can be selected by the users for data exchange during operation. Since the
IrDA interface can be used for data exchange in the invention, even though the input reading module 20 is not placed in the concavity 14, data transmission can be processed, thereby facilitating the operation for users.
Next, communication modes and transmitted data formats used in an embodiment will be described in accompaniment with pertinent drawings.
Referring to Fig. 4, normal data exchange processes are depicted, wherein Fig. 4(a) represents a state of nondata transmission and Fig. 4(b) represents a state of data transmission. During the data transmission, a client provides a request to a server and the server processes the received request from the client. In an embodiment, demanding data transmission is a main request format. In the following example, the telephone 10 and input reading module 20 act as a client and a server, respectively, but the roles of the telephone 10 and input reading module 20 are exchangeable. Furthermore, the data exchange interface 30 operates with a half duplex polling approach. That is, the data transmission directions are two-way, but only one way is allowed for data transmission at one time.
In the state of non-data transmission as shown in Fig.
4 (a), there is no data transmission in the input-reading module. When the telephone 10 emits an enquire data (EQD) request 400, since there is no corresponding data at this time, so it can not be processed. Fig. 4(b) shows a state of data transmission. As can be known from Fig. 4(b), after the telephone 10 emits an EQD request 410, the inputreading module 20 transmits a data response 412 out according to the EQD request 410. Moreover, when the telephone 10 receives the correct data response 412, an acknowledge response 414 is transmitted to the inputreading module 20, thereby ending the data transmission process. Furthermore, if the input-reading module 20 does not receive the acknowledge response within a predetermined time (timeout), a data response is re-transmitted to the telephone 10 to ensure that the data is correctly received by the telephone 10. Referring to Fig. 4(c), data 416 from the telephone 10 are transmitted to the input-reading module 20. After the input-reading module 20 correctly receives the data response, an acknowledge response ACK 418 is emitted out. Therefore, the data exchange between the telephone 10 and input-reading module 20 can correctly be implemented through the above-mentioned data transmission modes.
In addition, in order to detect and correct the data transmitted via a physical layer, a data structure of transmitted data packet based on a data-link layer protocol is defined as shown in Fig. 5. In Fig. 5, a message type 500 is used to explain the type of transmitted message, thereby defining different transmitting directions and receivers. For example, the message type transmitted from the telephone 10 to the input-reading module 20 must be different from the message type transmitted from the inputreading module 20 to the telephone 10, wherein a bit length is equal to a byte. An address code 502 functions as an identification between the telephone 10 and input-reading module 20, thereby ensuring a point-to-point communication between the telephone 10 and input-reading module 20 and avoiding interference from other devices, wherein a bit length is equal to a byte. A message length 504 shows the message length of message data 506 beneath the message length 504. The message data 506 represents the data after packing. The last field, a error detection 508, is used to correct the transmitted data, such as 16 bits cyclic redundancy, polynomial x16+x12+x5+1, wherein the bit length is equal to two bytes. Therefore, the receiver can be determined through the above-mentioned data packet structure to ensure the accuracy of transmitted data and achieve the object of the invention. In summary, the telephone device according to an embodiment of the invention can completely provide all functions as provided by a conventional intelligent telephone and allow the data to be easily brought for further processes.
Although the invention has been disclosed in terms of a preferred embodiment, the disclosure is not intended to limit the invention. Those knowledgeable in the art can make modifications within the scope and spirit of the invention which is determined by the claims below.
