Abstract: There is disclosed a photosensitive automatic controller for use with window coverings in particular for use with venetian blinds. The controller includes a reversible motor, a drive circuit, a photosensitive sensor, a user input, a control signal processor, a command circuit and a feedback sensor. The reversible motor is operably connected to the opening and closing device and it has a predetermined range from open to closed which corresponds to the window covering being fully opened and fully closed. The drive circuit is operably connected to the motor for generating a drive signal which drives the motor in a predetermined range from opened to closed. The photosensitive sensor generates a sensor signal. The user input generates an input signal. The control signal processor is operably connected to the photosensitive sensor and the user input and the sensor signal is combined with the input signal to produce a control signal.

Abstract: A folding stool including a top having a depending peripheral skirt and support leg members operatively mounted on the underside of the top, and inward of the peripheral skirt. Leg members are mounted at opposite ends of the stool. Each leg member includes two legs interconnected as a pair. The leg members are pivotally moveable to an extended stool support position, and to a retracted folded position within the confines of the skirt. Selectively engageable double leg locking means are provided, with portions thereof being on the stool top and portions thereof being on the legs of the leg members. The locking means are functionally operable for locking the leg members in the extended stool support position. Engagement and disengagement of the double locking means is manually effected by rectilinear movement of the leg members, toward the stool top when in the extended stool support position. Pivotal movement of the leg members is prevented with the locking means operatively engaged.
