Abstract: A bottle system includes a first housing having a first sealable opening and a distal end, between which a second sealable opening is located, and a first storage chamber being defined between the first and second sealable openings of the first housing. The bottle also includes a second housing having a second storage chamber defined between a third sealable opening and a base, with the first housing and the second housing adapted to be rotatably coupled relative to each other in an end-to-end configuration between at least a first state, in which the first and second storage chambers are separated from each other, and a second state, in which the first and second storage chambers are coterminous. The bottle also includes a cutter such that, in use, the cutter pierces seals of the second and third sealable openings as the first and the second housings are rotatably actuated.

Abstract: A resistance regulating device for a wheel of a training device is disclosed. The resistance regulating device comprises a rotary mechanism pivotally connected with a stationary mechanism and a motor with other components to rotate the rotary mechanism and hence a distance between magnets of the rotary mechanism and the wheel is changed. In addition, an optical detection device may be used to detect and define a minimum resistance and a maximum resistance and hence to adjust a resistance in a stepless manner. An emergency brake mechanism may be further employed.

Abstract: One transformable creeper includes three portions. The first portion has a frame, four wheels operatively coupled to the frame such that a lower edge of the frame is maintained above a lowermost point of the four wheels by no more than about two thirds the diameter of the four wheels, and a first support surface operatively coupled to the frame. The second portion has a second frame rotatably coupled to the frame and a second support surface. A lock maintains the second frame at three angles relative to the frame (generally 180°; between about 90° and 180°; and between 0° and 90°). The third portion has a third frame rotatably coupled to the second frame, two wheels, and a third support surface. A lock respectively maintains the third frame at two angles relative to the second frame (generally 180°, and between 0° and 90°).

Abstract: A transformable creeper has a movable frame that facilitates movement between an extended position and a seat position, as well as a storage position, and can support the human operator when lying and seated on the creeper. The creeper is of two pieces, that fold over each other tightly, so as to occupy minimal storage space. The creeper also includes a member that is pivotally mounted to the frame to function as a seat, that is easily accessible, when the frame is in the seat position and seating is desired.
