Abstract: A pneumatically activated signal flag is used in combination with a first watercraft to provide a visual warning to other watercraft operators of various events which may be occurring around the first watercraft. For example, the signal flag may indicate that a swimmer is in the water adjacent to the watercraft. The signal flag is raised or lowered by activation of a pneumatic activating ram by an operator within the water craft.

Abstract: A system and method for the on-site formulation of a personalized hair color maintenance shampoo product. The system and method are used to produce on-site of the salon a hair color maintenance shampoo product which is appropriately tailored to the color and tone of each individual's hair. A database information chart containing formulations of stock colored shampoos is correlated to a pair of sequential axes representative of hair colors and tones. A mixing bottle is provided which is calibrated to the formulations on the chart to obtain a shampoo product tailored to the individual's hair tone and color. The system and method yield a hair color maintenance shampoo personalized to the hair of the individual; eliminates the need to maintain an inordinate stock of pre-mixed hair colored maintenance shampoos and colors; and eliminates the necessity for an individual user to experiment with various stock shampoos.
