Abstract: A ridge vent end cap that can be readily bent to conform to roofs of varying pitches while enclosing ridge vents of various styles. The end caps are bent and fashioned for a flat blank, which is configured to allow it to be bent and formed into a shape that accommodates various styles of ridge vents and that encloses ridge vents on roofs with varying pitches. The bent finished end cap has a top ridge beam and a pair of end panels, bottom flaps and corner flaps. Each corner flap has its own top corner flap and a bottom corner flap. A preformed key hole slot along the central axis/plane of the blank or finished end cap allows the end cap to bend without buckling so that the end panels slide over one another to enclose the end open of the ridge vent while conforming to the pitch of the roof. A tooth is formed in one of the bottom flaps, which bites into the roof shingles helps ensure that the end panels cannot be pried up or burrowed under by rodents and insects.
Abstract: A system for supporting a household plant includes an electric circuit for selectively moving the plant having a battery and a direct current motor for moving the plant. The motor control is by a first controllable switching device to connect the battery to the motor with a first polarity to cause the plant to move in a first direction, or a second controllable switching device to connect the battery to the motor with a second polarity opposite the first polarity to cause the plant to move in a second direction. A controller selectively enables either the first or second switching devices while leaving the other disabled and in conjunction with a light sensing device and analog comparison circuit precludes actuation of either switching device if inadequate growth promoting light is sensed.
