Control system for coverings for architectural openings

A control system for a vertically moveable covering for an architectural opening includes a uni-directional drive assembly that is operated with a single pull element such that upon pulling of the pull element, the covering can be raised in increments. A clutch/brake assembly selectively prevents the covering from dropping by gravity between pulling strokes on the pulling element, but a release of the brake allows the shade to drop by gravity from its retracted position to any degree of extension. A governor is further provided to regulate the rate at which the covering drops by gravity. A cord lift system which is operated by the main drive assembly and the clutch/brake assembly includes a rotatable and axially slidable spool about which a lift cord can be wound. The lift cord has one end anchored to the spool and its opposite end extended through a supporting bracket for the spool and downwardly through the covering where the opposite end is anchored to a bottom rail such that a wrapping of the lift cord about the spool lifts the bottom rail thereby causing the covering to be raised adjacent to the lift spool. The lift cord is tangentially fed to the lift spool and forced into an angular wrap on the spool while an outer shell spaced a small distance from the spool prevents multiple wraps so that the lift cord does not become tangled. A return spring biases the spool in one direction to facilitate a controlled movement of the covering from a retracted to an extended position.

Fibers excellent in magnetic field responsiveness and conductivity and product consisting of it

InactiveUS20070003761A1Improve responseStable specific resistance valueCurtain accessoriesWarp knittingFiberHeat resistance
The present invention relates to fibers having excellent responsiveness to magnetic fields and excellent conductivity, as well as articles made of the same. In particular, the present invention relates to fibers having magnetic properties and conductivity, which are excellent in resistance to heat and responsiveness to magnetic fields in a unit where a magnetic field is applied, as well as in stability of conductivity when the humidity varies. In addition, the present invention relates to textiles using such fibers, knitted articles and cloths, such as non-woven cloths, short fibers, brush rollers made of short fibers, and electro-photographic apparatuses using brush rollers. The fibers of the present invention are fibers having excellent responsiveness to magnetic field and conductivity, made of a polymer having fiber forming functions which contains magnetic material particles in spherical form having a saturation magnetic flux density of no less than 0.5 tesla. According to the preferred aspects of the present invention, (a) the average particle diameter of the above described magnetic material particles in spherical form is no greater than 5 μm, (b) the coercive force of the above described magnetic material particles in spherical form is no greater than 1000 A/m, and (c) the above described fibers are complex fibers which are made of magnetic layers that contain 20 wt % to 90 wt % of the above described magnetic material particles in spherical form, and protective layers where the content of the above described magnetic material particles in spherical form is less than 20 wt %.

Intelligent gesture and voice control system of curtain and control method thereof

The invention discloses an intelligent gesture and voice control system of a curtain and a control method thereof. The control system comprises a gesture collection unit, a voice collection unit, an identifying unit and an external equipment unit, wherein the gesture collection unit is used for obtaining a gesture movement of a user through a camera; the voice collection unit is used for obtaining a user instruction through a microphone; and after the identifying unit is used for respectively identifying and judging a gesture and a voice, information of two channels is integrated according to a time sequence relation of an identified information flow. The curtain can be operated according to an integrated result. According to the intelligent gesture and voice control system of the curtain and the control method thereof, gesture control and voice control can be independently used and also can be used in a combined manner, so that a user has more natural and harmonious experiences in intelligent home furnishing. The gesture and the voice are combined to control the curtain at the same time so that the problem caused by manually opening and closing the curtain in the existing family is reduced and the quantity of remote controllers in the family is reduced; and meanwhile, elderly people and children in the family, and disabilities can conveniently use the curtain.
