  • Publication number: 20100318814
    Abstract: A point of sales (POS) terminal apparatus including a POS device, a peripheral device, which is controlled by the POS device, an adapter, and a power management device is provided. The adapter provides a first power signal based on a wall-outlet power signal. The power management device provides the first power signal to drive the POS device and determines whether the first power signal satisfies a predetermined condition. When the first power signal fails to satisfy the predetermined condition, the power management device generates a second power signal and drives the peripheral device with the second power signal. When the first power signal satisfies the predetermined condition, the power management device drives the peripheral device with the first power signal.

  • Patent number: 5617546
    Abstract: A removable CPU module for use in a data processing system. The CPU module includes at least one CPU having a first data width, and a first data bus of the same data width coupled to the CPU. A connector is coupled to the first data bus for connecting to a circuit board having a second data bus. The second data bus has a second data width which is different from the first data width. The CPU module is configured such that it is compatible with the second data bus. In one embodiment, the removable CPU module includes a third data bus coupled to the first data bus and the connector, which is a duplicate of and connected in parallel with the first data bus. The third data bus facilitates compatibility between the CPU module and the second data bus.
