  • Distance tracking for the remote control of an MP3 Player
    IEEE Transactions on Consumer Electronics, 2009
    Co-Authors: Ying-wen Bai, Yi-fan Huang
    Abstract:

    In this paper we propose a design with lowpower and distance tracking for both a remote control board and a monitor board for an MP3 Player. The design consists of a microprocessor, a GPS module, an RF module, six Tyco switches and a 2times 16 LCD display enabling the user to use all functions. Our remote control board supports a typical MP3 Player with 27 functions. In addition this design detects both the outdoor longitude and latitude which are received by the monitor board through the GPS and the RF module. The remote control board also receives longitude and latitude. The monitor board, after receiving the longitude and latitude data of the remote control board, determines the distance between the two boards and shows this in a LCD display which allows the user to track another MP3 Player user at any time. When the GPS is not able to detect a signal from a satellite we use the RSSI (Receive Signal Strength Indicator) register in the RF module to measure the distance between the two boards. We also use the RF module to transmit testing packages with identification codes, examine the number of packages that the monitor board has received and establish a table in order to calculate the distance according to the number of received packages.

  • Design and Implementation of an Automatic Testing System for MP3 Players
    2008 IEEE Instrumentation and Measurement Technology Conference, 2008
    Co-Authors: Ying-wen Bai, Chin-chung Lee
    Abstract:

    In this paper we design and implement an automatic testing system for MP3 Players. The automatic testing system includes several kinds of program code. For instance, "source function table" provides the program of operation functions, "picture table" provides the picture display, "transfer table" provides the test module transformation, "button table" provides the press button test and the test program which is stored with the main program of the MP3 Player in the NAND flash. When the operator turns the MP3 Player on, the first flag decides whether the test program will go into "automatic test mode" or "normal mode". When the first flag points at the automatic test mode, the MP3 Player executes the test program from the NAND Flash. It also guides the operator in carrying out the tests, such as sound effects, OLED display, record module, line in module, lock and press button.

  • Design and implementation of the integration applications for a portable MP3 Player with a bluetooth hand-free/set
    IEEE Transactions on Consumer Electronics, 2005
    Co-Authors: Ying-wen Bai, Chun-lee Chiang
    Abstract:

    Considering the demand for a wireless connection to a portable MP3 Player, we propose an integration design of a MP3 Player with a Bluetooth hand-free/set. The Bluetooth module serves as the wireless channels between the MP3 Player and the wireless headphone, the wireless microphone and recording memory cards, the FM receiver, and the cellular phone. Audio switches in our design are used to facilitate the corresponding audio paths. We have chosen a highly integrated chip set to fulfill the required functions, resulting in less power consumption, and in an extension of the recharge cycle, in this integration design, we use a simple operational amplifier with a negative feedback circuit to suppress the common mode noise resulting from high frequency signal coupling between the audio paths. Overall, our prototype design has already demonstrated good sound quality for a wireless MP3 Player.

  • Design and Implementation of a Table-based GUI for MP3 Players
    2006 IEEE International Symposium on Consumer Electronics, 1
    Co-Authors: Ying-wen Bai, F.-e. Fu-en Tsai
    Abstract:

    In addition to the two present methods for system control programming mechanism of MP3 Players, due to the marketing competition of MP3 Players, there is a need for a fast GUI design for various customers. The first method stores only the boot code in the ROM of the controller. The main program is stored in the NAND flash which includes the initializing program code. As long as the initialization is completed, the program code will be loaded into the system from the NAND flash. The advantages of this method are that the main program can update the GUI anytime and provide more flexibility. However, the chip area will increase due to the need of RAM for storing the program. The second method is to store the main program into the ROM of the controller, by which this design does not need to use an extra RAM in order to save the chip area. However, when the main program is once stored into the ROM, the function of the MP3 Player can not change any more. In this paper, we propose a table based GUI design which provides a fast way to obtain the different programmable GUI from the prestored NAND flash. A couple of tables are used to support various customer GUIs, such as, a command table for the basic operational procedure, a display table for the basic display components, a manual table for the basic function of the MP3 Player and a key table for the key function used with the MP3 operation. These tables can be prestored in the NAND flash module. When users turn on the MP3 Player, the main program of the MP3 Player will load in the customer required tables. Hence, by using our design, a different set of these tables will provide users with different GUIs even if the same chip set in the hardware modules is utilized

  • Design and Implementation of a Table-based GUI for MP3 Players
    IEEE Transactions on Consumer Electronics, 2007
    Co-Authors: Y.-w. Bai Ying-wen, F.-e. Fu-en Tsai
    Abstract:

    The keen competition in the market for MP3 Players has resulted in the need for another fast GUI design for a variety of customers in addition to the two current design methods of building the boot code or the main program into the controller chip to manage both the boot system control and display functions. In this paper, we propose a table-based GUI design which provides a fast way to obtain a different programmable GUI from a pre-stored NAND flash. Some tables are used to support various customer GUIs, such as a display command table for starting the display procedure, a display table for the basic display components, a menu table for the basic function of the MP3 Player and a button table for the button function used with the MP3 Player operation. These tables can be pre-stored in the NAND flash. When the user turns on the MP3 Player, the main program the internal ROM of the controller chip loads in the customer-required tables from the NAND flash. Hence, by using our design, a different set of these tables provides the user with different GUIs even if the same chip set in the hardware modules is utilized.

  • Implementation of MP3 Player for music therapy on hypertension
    2009 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2009
    Co-Authors: J.-y. Yu, D. F. Huang, Y Li, Y.t. Zhang
    Abstract:

    Hypertension is a common clinical disease and a major risk to human health. Many clinical findings indicate that certain types of music can reduce blood pressure (BP), and music therapy is considered as an important part of anti-hypertension treatment. We integrate our former related research achievement into the new MP3 Player, which can also detect the current BP value with a cuffless measurement method. According to the current BP value, the MP3 Player selects certain types of music for playing in order to alleviate the hypertension of patients.
