An electronic device includes a first housing, a second housing latching to the first housing, a resilient component assembled to the second housing, and an earphone jack assembly. A three layer cascade adaptive neural fuzzy inference system based intelligent controller is proposed for the mobile wireless network to optimize the maximum average throughput, minimum transmit power and interference for multimedia call services. The detachable filling element and the radioactive source are adapted to be inserted into a vessel at least in close proximity of a neck of an aneurysm. This virtually eliminates the corresponding constraint on the maximum number of robots that can be deployed to perform a task. The user control interface is to detect a user-selected time-range portion of the first plot in the time navigator. The control mechanism allows the physician to obtain a longer retracting stroke to the restraining sheath with a shorter actuating motion reducing the amount of manual actuation needed to be performed by the physician when retracting the sheath.
