A first user interface may be presented comprising a single selection option that enables recording of multiple television channels. The weather alert manager compares meteorological data, a user profile including information on points of interest to the user, and geographical data to determine if weather will impact one or more of the user’s points of interest. The sliders can be attached to the slide plate. The connect-release zipping system may be incorporated into a sleeping bag to allow the bag to easily transform into a jumpsuit. pinchoff voltage in the JFET is controlled by photolithographically defined spacing of the gate well regions, and hence exhibits low variability.
