Methods, systems, apparatuses, and computer program products for confirming attendance of prospective attendees to a meeting or events via time management or event scheduling applications, such as calendar applications, are disclosed. The method then constructs a thermal and an electrical load model based on the inputs and constructs an overall energy model, the overall energy model being based on the thermal and electrical load models. In order to be able to lay the connection line for the element in a simple manner, a screen which can be moved with the cover and which at least partially covers the lateral guiding device is provided. The hardware parity logic is then instructed to perform the appropriate parity computation, using the identified coefficient subset.
