Abstract: One or more embodiments disclosed herein relate generally to flotation devices, and more specifically to modular flotation devices with a mechanism to removably attach to other modular devices. In one embodiments, an apparatus includes a first flotation module and a first connector coupled to the first flotation module. The first connector has a first end portion, a second end portion and a sidewall extended from the first end portion to the second end portion. The sidewall defines a plurality of circumferentially defined stepped portions configured to matingly engage a second connector of a second flotation module to couple the first flotation module to the second flotation module. The first connector is selectively operative as one of a female connector or a male connector with respect to the second connector.

Abstract: Systems and methods of grading food items include a user customizable profile that allows a user to specify nutritional needs, dietary goals, or a medical state. The user profile is used to provide a user specific grade to one or more food items. This grade is configured for a user to compare food items and learn which provides better nutrition according to their profile. The user profile is optionally configured to take into account a medical state such as celiac disease, diabetes, or a nutritional deficiency. A grade can be provided for a single food item or to a list of food items.

Abstract: The child receiving device includes a seat, seat suspension arms for supporting the seat portion, and a support frame for supporting the seat suspension arms and the seat above a supporting surface. Two front seat suspension arms are pivotally connected at their lower ends to opposite front ends of the seat and two rear seat suspension arms are pivotally connected at their lower ends to opposite rear ends of the seat. The support frame includes a suspension guide, the upper ends of the front and rear seat suspension arms being pivotally connected to the suspension guide. The suspension guide includes a slot along which the upper ends of the front seat suspension arms may be moved toward and away from the upper ends of the rear seat suspension arms.
