Abstract: A prosthetic foot comprising an internal keel (1) and an encapsulation material (2). The keel (1) is made of two parts (3,4), namely an elastic ankle (3) and an elastic blade (4), to ensure a behaviour of the prosthesis as close as possible to the biomechanics of a sound human foot (plantar flexion, dorsiflexion, inversion, eversion). The materials and design used for the keel (1) allow storing and releasing strain energy at the right phases of the gait cycle. Elastomeric foams act as safety features in specific areas to prevent keel overloading. The keel (1) is preferably encapsulated into two types of foam to fill internal space and as cosmetic feature as it has a human foot shape.

Abstract: A mug cap apparatus comprises a mug cap and a mug. The mug cap comprises a base cylindrical body having a hollow opening in the center. The base cylindrical body has a narrow portion and a wide portion. A sealer ring seals the base cylindrical body to the mug. The wider portion engages the rim of the mug and the narrow portion engages the inner perimeter portion of the mug. The hollow opening has threads to engage a compartment's cylindrical body. The compartment's cylindrical body has an outer perimeter that has threads to engage the threads of the base cylindrical body, and an inner compartment. A lid engages said compartment cylindrical body and seals said inner compartment when said lid is in its closed configuration.

Abstract: A modular filter for a vacuum mug comprises a mug cap and a first filter basket. The mug cap has a bottom opening and a threaded wall. The modular filter further comprises a first cylindrical connector having a first opening, second opening, and circular screen filter positioned between the first and second opening. The bottom opening of the mug cap is attached to the first opening of the cylindrical connector, and the filter basket is attached to the second opening of the cylindrical connector. The first filter basket comprises a cylinder having cylindrical screen filter, a top opening and bottom base. Its top opening is attached to the second opening of the cylindrical connector. The bottom base comprises filtration holes.

Abstract: A mug lid apparatus comprises a base cylindrical body having a primary base hallow opening in the center and a secondary base hallow opening situated along the perimeter of the cylindrical body opposite to the primary base hallow opening. The top cylindrical body is attached to the base cylindrical body. The top secondary hallow opening is situated along the perimeter of said top cylindrical body. The top cylindrical body is rotational against the base cylindrical body. When the primary base hallow opening is aligned to the primary top hallow opening, the secondary base hallow opening is not aligned to the top secondary hallow opening.
