Abstract: An electronic pricing system, includes price label system server adapted to communicate with a price controlling application (PCA) server communicating price label information to price labels (PLs). The system is designed to generate control signals for updating price information related to at least two separate sales items that are both/all logically linked to an individual price label in the system, the price label being designed to receive the control signals and to display the price information for each item separately.

Abstract: A hardware design emulation system that includes one or more emulators and one or more associated run-time assist units (RTAUs). The emulator logic is a combination of user model logic, reflecting the hardware design, and non-user model logic. A handshaking controller produces a domain step signal and a model step signal. The domain step signal indicates that the emulator is entering a state for executing the next step of the logic with which it is programmed, be it user model logic or non-user model logic. The model step signal indicates that the emulator is entering a state for advancing the user model defined by the user model logic. This dual handshaking protocol enhances versatility by enabling a wide variety of RTAUs to be used, particularly in combination with one another.
