Abstract: A light source module including: at least one lighting seat bodies equipped with light-emitting diodes, the light-emitting diodes being connected with a lighting circuit, whereby after the lighting circuit is closed, the light-emitting diodes are driven and lighted; and a light guide medium, at least one face of the light guide medium being defined as an incident face right facing light-projecting faces of the light-emitting diodes. A back face of the light guide medium is printed with multiple reflective sections. The light coming into the light guide medium is reflected by the reflective sections to a front face of the light guide medium and goes out from the front face.

Abstract: An electronic pen device is proposed, which can be coupled to a computer platform having a display unit and an input-sensing unit, allowing a user to manually input data and/or graphs to the computer platform via the electronic pen device. The electronic pen device includes a micro-processing unit (MPU), a storage unit for storing color-corresponding codes, an input unit for allowing the user to set a display color for the handwriting data and/or graphs to be displayed on the display unit, and a signal output module. The MPU retrieves a color-corresponding code from the storage unit corresponding to the set display color and sends a color signal corresponding to the color-corresponding code to the signal output module that further sends the color signal to the computer platform. The display unit then displays the handwriting data and/or graphs in the set display color responsive to the color signal.

Abstract: A digital display system is proposed, which is characterized in provision of a digital board composed of a plurality of currently-available printed circuit boards, wherein each pair of adjacent printed circuit boards are electrically interconnected by a plurality of conductive coupling wires, so as to integrally form a large-scale panel for the digital board. This characteristic feature allows the digital board to be simply fabricated by a currently used jig and flexibly enlarged in dimension according to practical requirements without increasing costs for developing a newly designed jig, thereby making fabrication processes cost-effective to implement.

Abstract: A projection device is provide, including a projection module having at least an optical lens, the projection module receiving data and converting display data into an optical image to be projected on a display area by the optical lens. The projection device can be positioned substantially close to the display area. This allows the projection device to directly project the optical image on the display area without having to adjust a projection angle, and also makes the projected image free of obstruction from movement of a user. Therefore, data display and projection operation can be conveniently and efficiently implemented.

Abstract: A multi-port multi-channel bi-directional communication device is proposed, which is designed for use with an information platform with audio I/O capability, such as a PC, a public information station, a mobile phone, a network video phone, a PDA, and the like, and which is provided with at least one network connecting port (such as RJ45 port) and at least one dial-up phone connecting port (such as RJ11 port), for the information platform to be selectively connected to either the Internet or the PSTN to provide either a VoIP (Voice over Internet Protocol) phone function or a dial-up phone function. The proposed communication device is characterized by that both the VoIP phone function and the dial-up phone function can be performed in a bi-directional way; and the VoIP phone function allows both static-to-dynamic and dynamic-to-dynamic IP address phone linking capability.
