PB07: Enabling Low Cost Chargers for Portable Systems
Track: Portable Products
Speakers: Jason Hansen, Applications Engineer; Jim Hill, Applications Engineer, ON Semiconductor

This paper describes how proper design of an AC/DC adapter can help with power dissipation issues in portable devices. This approach enables portable designers to minimize the power lost across internal pass devices by controlling the output characteristics of their chargers. It also enables the designer to implement an extremely cost-effective charging solution. The approach simply uses a 50/60 Hz transformer as the AC/DC converter and a current limiting resistor (or winding resistance) as the current limit. The only active electronics in the AC/DC converter is the diode bridge. The output voltage will drop with current due to this current limiting resistor. Therefore, the charge control in the portable device must account for this. Since the output voltage drops with current, the voltage drop across the pass device also decreases which lowers power dissipation. This enables the designer to use smaller devices to save space. When one designs the transformer, the resistor and the charge control scheme correctly, one can realize an extremely cost-effective and space efficient solution. The paper will show examples of one to three NiMH cell charging schemes, and some one-cell Li-ion charging schemes. The information presented comes from the design and testing of various charging schemes, research into portable battery systems and the implementation of various integrated circuits into portable systems.

PB08: Rotating-Wheel Braille Display Provides Accessibility for Compact Portable Devices
Track: Portable Products
Speaker: John W. Roberts, Program Manager, NIST

More than ten years after the passage of the Americans with Disabilities Act, and with the explosive growth of the Information Economy, information accessibility is more important than ever before. Calls for accessibility are extending to portable information devices, and are being met by several different approaches in response to the needs of the user community. For many blind and visually impaired users, refreshable Braille displays offer a powerful means to access, but their use for small portable devices has been hampered by high cost and by the tradeoff between bulky structure (for long lines of Braille text) and inconvenience of use (for short lines of text). The NIST rotating-wheel Braille display technology places refreshable Braille text on the rim of a rotating wheel, giving the functionality of long lines of Braille text in a space as small as two inches or less. A high level of performance, plus very low cost of manufacture, will provide a powerful accessibility solution for small portable devices.
