A device for collecting data relating to a cooking andor heating process performed on a hob comprising at least one sensor associated with wireless data transmission means and means for receiving the signals transmitted from the data transmission means and connected to a hob management system for the purpose of permitting automatic control of the process. In the method provided by the embodiments of the present invention, only the primary uplink is used, which reduces the link bandwidth waste of the multicast host and improves the multicast data transmission efficiency. An attachment mechanism is coupled substantially about the periphery of the sleeve. The angle of incidence of the hydrofoil is controlled by a sensor arm carrying a trailing sensor. The invention also relates to embodiments of said method. Also provided are systems and methods for copying a memory space by a memory controller to a memory space under exclusive control of the memory controller.
