Automatic limit detection for horizontal sheers style roller shade
A system and method for automatically determining at least one lower limit of a horizontal sheers style roller shade. The roller shade comprising a roller tube, a shade material attached to the roller tube and comprising a first vertical layer interconnected to a second vertical layer via a plurality of horizontal vanes, a motor adapted to rotate the roller tube, a current sensing circuit adapted to detect current levels of the motor, and a controller adapted to control the motor and comprising at least one memory. The controller determines at least one lower limit by driving the motor in a first direction, receiving current levels from the current sensing circuit, observing current level profile of the received current levels, detecting a point of change in the current level profile, and using the point of change to set at least one of a lower tilt closed limit and a lower tilt open limit. During normal operation, the controller drives the motor between the upper limit and the lower tilt closed limit to raise or lower the shade material and between the lower tilt closed limit and the lower tilt open limit to open or close the vanes. |

Slat for a blind and blind formed therefrom
A blind made up of a plurality of customisable rigid slats enables the blind to be fitted snugly within any window opening or doorway as a result of the locking adjustability of the width of such slats. The slats each include a pair of elongate slat panels movable relative to one another between retracted and extended conditions, such that the operative width of the blind is greater in the extended condition than in the retracted condition. The blind further includes one or more fasteners, located at or near each of a pair of minor ends of the slat panels, for releasably fixing the pair of slat panels to one another in the retracted condition, the extended condition and/or any condition there between, thereby to operatively restrict relative movement between the slat panels in such condition. |

Vacuum insulating material and vacuum insulating glass
Vacuum insulating glass or other such vacuum insulating material may be provided with a first plate and a second plate that are arranged in mutually opposed fashion so as to straddle therebetween a space of a gap that is a vacuum layer. The first plate may have, in order of lamination from the exterior, a first electrically conductive layer, and a first charged insulator. The second plate may have, in order of lamination from the exterior, a second electrically conductive layer, and a second charged insulator which is charged with charge of the same polarity as the first charged insulator. A repulsive force that is a Coulomb force which acts between the first charged insulator and the second charged insulator may substantially balance and counteract a tendency of ambient atmospheric pressure to reduce the length of the gap between the first plate and the second plate. |

Movable barrier operator and method
A movable barrier operator includes a communication interface configured to receive commands that cause the motor to move the movable barrier. The movable barrier operator further includes a processing circuit configured to cause the motor to automatically move the movable barrier from a first open position toward a closed position and then from the closed position toward a second open position different from the first open position in response to receipt of an intermediate open command by the communication interface. The processing circuit can also cause the motor of the movable barrier operator to move the movable barrier toward the first open position in response to the processing circuit determining that the movable barrier had been obstructed while moving from the first open position toward the closed position. |

Vehicular opening/closing body control device
A vehicular opening/closing body control device includes: a braking control unit configured to apply a braking force to an opening/closing body provided in an opening in a vehicle; a traveling state determination unit configured to determine a traveling state of the vehicle; an abnormality detection unit configured to detect occurrence of a full-closing abnormality in which the opening/closing body is not held in a fully-closed state during the traveling of the vehicle; and a record holding unit configured to hold a detection record of the full-closing abnormality, wherein the braking control unit executes braking control through detection of the full-closing abnormality of the opening/closing body, and in a case where the detection record of the full-closing abnormality is held after the vehicle stops, executes the braking control of the opening/closing body based on the detection record of the full-closing abnormality before the vehicle travels. |
