Abstract: A liquid jet ejection device is provided. The liquid jet ejection device has a flexible lumen having an intake end positioned to be in fluid communication with a liquid source, and an output end distal from the intake end. A pump is coupled to the flexible lumen, the pump being actuatable to eject a liquid from the liquid source via the output end. A body structure extends from a handle and supports the output end of the flexible lumen, the body structure having a base form in which the output end of the flexible lumen is supported in a base pose relative to the handle, the body structure being deformable from the base form via contact with an object, the body structure returning to the base form upon withdrawal of contact.

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.
