• QBIC - Q-Belt Integrated Computer

Q-Belt Integrated Computer «QBIC»

Customer: ETH Zurich (IfE)

Designed to be comfortable to wear without compromising reliability «QBIC» is not just a wearable computer, it also serves a classic function… keeping your trousers up! Heart of the «QBIC» is a Intel Xscale CPU (Intel PXA263B1C400) which runs at a variable speed up to 400 MHz. The belt contains a battery, real-time clock and system bus extension for peripherals. Moreover the belt provides plugs for USB and serial devices (RS-232), VGA connector and power connector which can be used to attach to a mains supply, or an additional belt-attachable battery.

The buckle, which can be removed from the belt and slotted onto a developer board (for convenient programming), contains two circuit boards:

  • a main board with the CPU, SDRAM and power supply, and
  • an extension board with the Bluetooth device, USB controllers and an MMC card slot
  • QBIC - Transparent
  • QBIC - Size Comparison
