An invention is provided for fault-tolerant and adaptive communication in a distributed computing environment. The invention improves the ability of a driver or passenger to adjust and maintain the relative orientation of in-dash mounted electronic equipment for improving the ease with which electronic equipment may be utilized. A second algorithm is provided by means of which all the ATM cells in a frame, from a first cell to a last cell, are removed on arrival in a queue from the ATM communications device. The apparatus also includes a card configured for insertion into the card reader. Other embodiments of a mutual capacitance touchscreen are also disclosed, such as \u201cmini-diamond\u201d sensor array patterns and sensor array patterns that may be manufactured at low cost. The three-dimensional body of the formation aid includes a narrow end, for placement near an interior edge of the swimming pool during formation of the swimming pool; and a wide end, for placement remote from the interior edge of the swimming pool, in order to form a receptacle.
