An object model of a first type such as an avatar is analyzed, and an object model of a second type, such as a clothing model, is generated. A compound that can be electrically decomposed to release on demand and over an extended period of time, an oxidant is included in the layered structure, preferably in the electrolyte layer. The tissue-penetrating member has a leading end and a trailing end, and provides a receiving space for receipt of an implant body portion for carrying the implant body portion into the volume of patient tissue. Optical receiver and transceiver modules may also be incorporated into the circuit module. The elongate support member comprises an improved catheter shaft design that maintains pushability, flexibility, and torquability while limiting kinking. This printing ink composition can inhibit color bleeding not only on a printing medium specifically designed for ink-jet printing but also on plain paper.
