CROSS REFERENCE TO RELATED APPLICATIONS

This Non-provisional application claims priority under 35 U.S.C. §119(a) on Patent Application No(s). 096109077, filed in Taiwan, Republic of China on Mar. 16, 2007, the entire contents of which are hereby incorporated by reference.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to a tool for presentation and more particularly to a Bluetooth transmission module applied in a pen-like tool for presentation.

2. Description of the Related Art

Recently, since wireless technology achieves rapid advancement and has been applied in different applications, it becomes more convenient for people to communicate with each other. For example, an infrared pen-like tool prevents users from staying near the computer to operate. The users thus can control the computer in a long distance. Therefore, the pen-like tool increases the efficiency when users hold a meeting and becomes an indispensable tool for the businessperson nowadays.

Referring FIG. 1, FIG. 1 shows a block schematic diagram of a conventional pen-like tool for presentations. The conventional pen-like tool for presentations utilizes infrared technology to transmit signals. Thus, signals from a microprocessor 12 are transformed into infrared rays and to be transmitted to a computer 17 with presentation software via an infrared module 11 to proceed with a presentation. However, the use of infrared technology is limited to a predetermined direction and distance. Thus, there is a lot of limitations for using the conventional pen-like tool to present. In addition, if an interfering source 19, such as cell phones, PDAs or other electronic products are applied in similar frequency or surrounding with the conventional pen-like tool, the conventional interfering source 19 will make the computer 17 and the pen-like tool unable to transmit signals to each other. Moreover, lack of uniformity for infrared technology delays the development of infrared technology and causes great inconvenience for the user.

Meanwhile, a user also requires remote control functions, such as sound recording, sound amplifying, and indicating or other functions during a presentation. Thus, a speaker must prepare not only the conventional pen-like tool 1 but also other devices such as a microphone for recording or a laser pointer for pointing at the screen during a presentation. As a result, the speaker must prepare many devices, and it is very inconvenient for the speaker.

DETAILED DESCRIPTION OF INVENTION

The following description is one embodiment of the present invention. This description is made for the purpose of illustrating the general principles of the present invention and should not be taken in a limiting sense. The scope of the present invention is best determined by reference to the appended claims.

FIG. 2 is a block diagram of a pen-like tool for presentations of the present invention. FIG. 3 is a schematic illustration of a pen-like tool for presentations of the present invention. Referring to FIG. 3, a pen-like tool 2 for presentations includes a main body 26 and a Bluetooth transmission module 21 disposed in the main body 26. The main body 26 is assembled by a top shell 26a and a bottom shell 26b. The top shell 26a and bottom shell 26b are made of different materials. The main body 26 has a clip disposed on the top shell 26a. The clip is used as an antenna 25 of the Bluetooth transmission module 21 for transmitting and receiving radio signals. The top shell 26a can be made of macromolecular polymers and the bottom shell 26b with an opening 0 can be made of metal to prevent shield effect from influencing the antenna 25. The Bluetooth transmission module 21 has a universal asynchronous receiver/transmitter or an inter-integrated circuit to receive/transmit a signal from/to the microprocessor 22.

Furthermore, the pen-like tool 2 is provided not only for presentations but for other functions. If a user wants to switch on other functions, he or she can press buttons B and B′ disposed on the pen-like tool 2 to start other functions easily. The pen-like tool 2 includes a microphone 23. Thus, if the sound record function and sound amplifying function are used, pressing the button B starts the microphone 23 to receive a sound from the outside of the pen-like tool. The sound from the outside of the pen-like tool is transformed into a signal by an inner radio frequency circuit of the Bluetooth transmission module 21. The signal is transmitted to the electronic device 27 via the antenna 25. After an audio processing software of the electronic device 27 processes the signal, sounds are saved via the audio processing software. If the electronic device 27 is connected to an amplifier 28, for example a speaker, sound can be broadcasted. Furthermore, the pen-like tool 2 further includes a laser light source 24. If a user uses the indication function, the button B′ is pressed to reach what is being indicated. Compared with conventional pen-like tools, using the pen-like tool of the present invention avoids the trouble of bringing many devices for a presentation and provides a single common power source in the same device.

The Bluetooth transmission module 21 uses frequency-hopping transmission, thus, the electronic device 27, such as a computer, for remote control is not interfered by the same frequency band for radio frequencies. When the signal is transmitted from the pen-like tool 2 to the electronic device 27 and then the software of the electronic device 27 processes the signal, the pen-like tool 2 can remotely control presentation software, such as Microsoft PowerPoint. That is to say, the computer uses application software not only for providing audio processing but also for presentation. Compared with other radio frequency technologies, the pen-like tool 2 uses less power and with a longer duration.

Referring to FIG. 3, the pen-like tool 2 is used not only for presentations but also for writing. When a user easily twists the bottom shell 26b, a refill C rotates and protrudes from the opening 0. Thus, the pen-like tool 2 becomes a portable writing tool with stylish appearance. Thus, the usability of the pen-like tool 2 of the present invention is improved.

The pen-like tool 2 improves the problem of interference and the problem about the limitation of an indicated direction. The pen-like tool 2 has multi-functions to eliminate carrying many devices. The pen-like tool 2 is further used as a writing tool, thus, it is convenient for the businessperson.

While the present invention has been described by way of example and in terms of the preferred embodiments, it is to be understood that the present invention is not limited to the disclosed embodiments. To the contrary, it is intended to cover various modifications and similar arrangements (as would be apparent to those skilled in the art). Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
