One or more network devices send to a user device a user interface with options for configuring a network to provide transaction services between transaction devices and host processing devices. Multiple computation modules are configured for concurrent execution of the portions of a timing analysis computation, for example, a static circuit timing analysis computation. The frame may accommodate placement of an unfolded or partially folded flexible circuit board so that a fold-assisting feature, such as a hinge, incorporated into the frame attaches to the flexible circuit board and closes around a pivot point to gently bend the circuit board into place, thus creating a three-dimensional folded circuit. Then the signal receiving device and method apply signal processing to the portion of the data that has been selected, separated and extracted. The accelerometer is preferably in communication with a data processing device or system, which data processing device is able to use signals from the accelerometer to perform one or more actions, such as, for example, displaying the angular difference. For sending an electronic mail message generated by the user, the user identifier obtained from the network can be used by the apparatus configured in this way to automatically fill in a sender field of the message, without the need for the user to enter it himself among the configuration parameters of his mail program.
