A handwriting board with a liquid crystal display (LCD) includes a wireless Universal Serial Bus (USB) unit, a USB hub unit, a USB/Video Graphic Array (VGA) conversion unit, a LCD driver unit, a LCD unit, a touch pad controller unit and a touch pad unit. When a user writes on the touch pad unit, the content written by the user is transmitted from the touch pad controller unit and the USB hub unit 204 to the wireless USB unit, which transmits the written content to a computer for processing. The processed written content is then transmitted to a projector and the wireless USB unit. Thereby, the written content can be displayed on the LCD unit.

摘要:
The invention relates to a fuel processor that produces hydrogen from a fuel. The fuel processor comprises a reformer and a heater. The reformer includes a catalyst that facilitates the production of hydrogen from the fuel; the heater provides heat to the reformer. Multipass reformer and heater chambers are described that reduce fuel processor size. Single layer fuel processors include reformer and heater chambers in a compact form factor that is well suited for portable applications. Some fuel processors described herein place an electrically resistive material in contact with a thermally conductive material to heat fuel entering the fuel processor. This is particularly useful during start-up of the fuel processor. Fuel processors described may also include features that facilitate assembly.
