A virtualized computer system provides fault tolerant operation of a primary virtual machine. Each semiconductor chip is provided with an outer lead for clock enable to which the clock enable signal and chip select signal are individually input. When a connection request is issued to the terminal, the RNC refuses assignment of a dedicated channel to the connection request when determining that the assignment of the dedicated channel to the terminal cannot be done based on the reception capability information at the time of selective combining. The plurality of electrical contacts are configured to establish electrical contact with corresponding electrical contacts on the inkjet printhead upon insertion of the inkjet printhead into the printing device. These studies are then analyzed to determine the locus of the tinnitus, and one or more electrodes are placed at the indicated region in the patient’s brain and a stimulation device for outputting a varying control pattern of electrical signals to the electrodes is also implanted. A data point indicative of the value of the variable activation signal applied to the actuation device is captured when the steering motor begins to rotate in response to energization of the actuation device.
