An overboard tracking patch is an apparatus which increases the visibility and tracking capabilities of Personal Flotation Devices (PFDs) for more efficient tracking of overboard individuals. In a passive embodiment, the apparatus includes an outer layer, an intermediate layer, an attachment layer, and a processor. The outer layer increases the visibility of PFDs during both daytime and nighttime conditions. The intermediate layer provides radio identification capabilities for the remote tracking of PFDs using search radars. The attachment layer enables users to attach the present invention to a PFD. The processor stores PFD information and other identification data. In a hybrid active-passive embodiment, the apparatus also comprises a thermionic layer and a power-storage layer. The thermionic layer generates power due to the heat exchange between the body of the user and the thermionic layer. The power-storage layer serves to store power generated by the thermionic layer to power up the processor.

Provided is an electricity generating module. The electricity generating module comprises: a cylinder; a piston that reciprocates inside the cylinder; and a power generating fiber of which one end is fixed to the piston and the other end is fixed to the cylinder, and of which the length varies according to the reciprocating of the piston, wherein, as the length of the power generating fiber varies, a potential value of the power generating fiber varies, and electricity is generated by using the varied potential value of the power generating fiber.

A floating physical therapy device includes a frame and a harness. The frame includes an inner frame and an outer frame on the right and left side. The inner frame defines a patient area. The harness is attached to the inner frame such that it secures a patient to the device in a substantially upright position during use. The frame extends forwards and backwards, as well as to the left and right, of the patient area in order to provide stability in the water during normal use. The frame defines a trainer area immediately forward of the patient area where a therapist can have access to the patient during therapy sessions.

An underarm float for infants, comprising a main body, the main body is composed of a front part and rear parts, which are connected to each other, wherein rear parts are connected to both ends of the front part, and rear parts at the two ends of front part are oppositely arranged; a first arc groove and second arc grooves are formed at the joint between front part and a rear part, first arc groove is downwards recessed along the upper surface of the front part and the rear part, and the second arc grooves are inwards recessed along the side surface of the front part and the rear part; a shoulder strap is arranged at the joint between the front part and the rear part, and the shoulder strap is located above the first arc groove; and the oppositely arranged rear parts are provided with an elastic cord.
