An electrical energy storage device for storing electrical energy and supplying the electrical energy to a driving motor at different power levels is disclosed. The electrical storage device has an energy battery connected to a power battery. The energy battery has a higher energy density than the power battery. However, the power battery can provide electrical power to the electrical motor at different power rates, thereby ensuring that the motor has sufficient power and current when needed. The power battery can be recharged by the energy storage battery. In this way, the power battery temporarily stores electrical energy received from the energy battery and both batteries can provide electrical energy at the different power rates as required by the motor. The energy storage device can be releasably connected to an external power source in order to recharge both batteries. Both batteries can be recharged independently to optimize the recharging and lifetime characteristics of the batteries.

An ostomy appliance is disclosed in which the adhesive faceplate for holding the appliance in place is of inverted triangular shape with rounded corners. The faceplate includes an adhesive layer composed of a hydrocolloid-containing pressure-sensitive adhesive, a protective release sheet removably covering the bodyside surface of the adhesive layer, and a flexible backing layer covering the opposite (pouchside) surface of the adhesive layer and permanently securing the faceplate to an ostomy pouch about the perimeter of a stoma-receiving opening. Because of its orientation, the triangular faceplate has one of its side edges extending across the upper end of the pouch (i.e., facing upwardly when the pouch is worn), resulting in a construction in which the area of the faceplate's adhesive layer is wider above the faceplate's opening than below it. In a preferred embodiment, the adhesive layer is recessed or set back at one of the faceplate's upper corners to provide both the release sheet and backing layer with non-protruding tab portions that facilitate both application and removal of the appliance.
