A portable computer can be âhotâ docked to one or more expansion devices, such as a drive wedge and a port replicator. As such, the expansion devices can be connected to and disconnected from the portable computer while portable computer is powered on and fully operational. The portable computer includes control logic that detects when an expansion device is connected to or disconnected from the portable computer and asserts an SMI or equivalent interrupt signal to the computers CPU to initiate a sequence of events by which the computer determines whether an expansion device has been connected or disconnected. If the CPU determines that the expansion device has been connected to the computer, the CPU appropriately reconfigures itself to communicate with the expansion device. If the expansion device is disconnected, the CPU also appropriately reconfigures itself to preclude communications with the disconnected device.

Data bus system and method in which a plurality of data lines extend between functional units, and data signals having a predetermined voltage swing are sent from one unit to the others over the data lines. The sending unit also generates a reference voltage at the mid-point of the voltage swing, and this reference voltage is sent to the other units on a reference line for comparison with the signals on the data lines.

Disclosed herein are methods and systems to generate and communicate interactive digital receipts. In one implementation, the method may include receiving an indication of a payment transaction between a merchant and a user. Via a customer identification system, an employment profile of the user; may be determined. The employment profile of the user may be compared with one or more employment vacancies within an employment database, where the employment vacancies relate to employment at one of a location of the merchant and another merchant's location. A particular employment vacancy from among the employment vacancies may be selected. The payment processing system generates one or more interactive receipts including at least a transaction component configured to display details of the payment transaction and an employment application component configured to display the particular employment vacancy.
