Abstract: A liquid powered assembly including a housing; a removable bottom base; a seal; an electrolyte battery assembly; and, a liquid powered device is described. The housing includes an upper end portion and a lower end portion. The housing has a volume for containing an electrolyte solution. The lower end portion has a fluid inlet. The removable bottom base has a bottom surface for supporting the liquid powered assembly. A seal engages the housing and the removable bottom base to help contain the liquid. An electrolyte battery assembly is positioned within the housing. A liquid powered device is operably attached to the electrolyte battery assembly. To function, the housing and the removable bottom base are detached relative to each other and the housing is turned substantially upside down to allow filling of the housing via the inlet. The bottom base is then attached to the housing and the assembly is then inverted for use.

The housing includes an upper end portion and a lower end portion. The housing has a volume therein for containing an electrolyte solution. The lower end portion has a fluid inlet. The removable bottom base is removably attached to the lower end portion of the housing. The removable bottom base has a bottom surface for supporting the liquid powered assembly. A seal engages the housing and the removable bottom base for providing fluidic sealing engagement therebetween. An electrolyte battery assembly is positioned within the housing. A liquid powered device is operably attached to the electrolyte battery assembly. To provide operation, the housing and the removable bottom base are detached relative to each other and the housing is turned substantially upside down to allow filling of the housing via the inlet.

Abstract: Improved impact cushioning within a shoe is provided by a novel heel hammock recess formed beneath the heel of the wearer. The heel hammock recess includes an elastic member supporting the wearer's heel surrounded by a surround surface formed to bear substantial weight. The impact energy transmitted upwardly through the heel to the wearer's foot during heel impact passes through the elastic membrane of the heel hammock allowing flexing and energy absorption to occur as the heel is cradled in the heel hammock. Embodiments are shown in which the impact absorbing member is formed integrally with a molded athletic shoe sole as well as alternative embodiments in which the impact absorbing structure is formed in a removable insole and also formed in a variety of general use shoes.
