Abstract: The invention provides a method for improving the emotional development of an infant by performing controlled exposure of the infant aged less than six months old to human fear pheromone, preferably with visual fear stimuli, so that the natural synaptic connections in the brain associated with normal fear mechanisms are stimulated and exercised. This can reduce the occurrence of mental illness later in life, in particular reduce the occurrence of schizophrenia. Advantageously the exposure to fear pheromone and visual fear stimuli is terminated and followed by comforting stimuli such as feeding, physical contact, or comforting or happy visual or audible stimuli such as laughter.

Abstract: The method of the present invention proposes to induce emotions of happiness or joy in a pregnant mother, with the intended result that the pleasant emotions can then be transmitted to the foetus through the normal mother-foetus communication.

Abstract: A method of controlling the Sleep pattern of a baby by monitoring its state of sleep to ensure that it enters rapid eye movement sleep to ensure proper development of its central nervous system. If the baby does not enter the rapid eye movement sleep phase, then the baby may be frozen and is reawakened and comforted with smiles and laughter before being returned to sleep.

Abstract: A fluid mixing valve comprising a housing provided with two fluid inlet ports and an outlet port for discharging fluid from the housing, a valve member within a bore in the housing axially movable in the bore for controlling fluid flow from the inlet ports to the outlet port and rotatable in the bore for controlling the relative volume rates of flow through the two inlet ports. The valve member is provided with two arcuate control surfaces eccentric in relation to the axis of rotation of the valve member and each co-operable with separate ones of the ports for inversely controlling, responsive to rotation of the valve member, the relative rates of flow through the individual inlet ports. Preferably one of the control surfaces co-operates with one of the inlet ports and the other co-operates with the outlet port for controlling relative fluid flow through the two inlet ports.
