A liquid additive dispensing apparatus for dispensing a liquid additive into a washing machine having a tub accommodating a fluid and a basket rotatably disposed in the tub. The first toy element includes a transmitter generating sub-audible sounds. Logic may implement two or more long training sequences for the first bandwidth mode of operation to transmit information based upon the selection of the particular long training sequence for the transmission. When the hypervisor is notified that the hardware has detected the guest operating system instructing a central processing unit to execute code stored in virtual memory accessible by user space while the CPU is in supervisor mode, the hypervisor may consult a policy to identify what, if any, responsive action the hypervisor should perform.
