An embodiment of the current invention is directed to facilitating a location-based service for use by a given mobile-device. In one aspect, the stent includes a butterfly pattern to which connecting links are attached. The implementation of the throttling process can be varied, to include additional levels of response or finer gradations of the response, to include subsets of a class of services. One of a low-friction supporting element and an electrically insulating supporting element in a form of an insulating body laterally guides the locking pawl. The shelf may extend forward from the front end opening of the slot, and can support a portion of the information handling system when the guide structure is not received in the slot.
