  • Patent number: 9816317
    Abstract: A spring-assisted cordless roller shade without clutch system includes a tubular body defining an internal space. A shade is wound on the tubular body. The internal space has a first section and a second section. In each of the first and second sections are mounted a connector, a central shaft assembled with the connector, a fixing member connected with the central shaft and a subsidiary shaft disposed on the fixing member. An elastic member is disposed between the connector and the central shaft to provide a frictional force. A rotational member and a torsion spring are mounted on the subsidiary shaft of the first section and rotatable along with the tubular body. A constant force belt spring module is assembled with the subsidiary shaft of the second section. When the operational force applied to the shade disappears, the shade is immediately located.

  • Publication number: 20170105524
    Abstract: A support device includes a support element, a linking element and a blocking element. A mounting path is formed on the support element for holding a plurality of mounting elements of an object. The blocking element is configured to be driven by the linking element. When the blocking element is located at a first position, the blocking element blocks the mounting path of the support element. When the blocking element is located at a second position, the blocking element does not block the mounting path of the support element.

  • Publication number: 20160245017
    Abstract: A drive system for a window treatment blind provides cordless operation of the blind in that the blind may be moved between a retracted position and an extended position without the typical user activation of a lift cord. The drive system includes an actuator with a spring tensioned spool that winds the lift cord as the blind is retracted and unwinds the lift cord as the blind is extended. The drive system eliminates the strangulation hazard to children presented by conventional lift cords.

  • Publication number: 20030115164
    Abstract: The present invention relates to an artificial neural network (ANN) representation for system dynamics models (SDMs) and its applications in model construction and policy design. It first shows that, by a special design of the mapping scheme, a given flow diagram (FD) (i.e., traditional representation) can be transformed into a corresponding model in the representation of partial recurrent networks (PRNs) that will correctly behave like the one it mimics. The present invention shows the equivalence of the two types of representations, both structurally and mathematically. With the additional representation, an automatic learning method that can assist in the construction of SDMs is proposed, which starts from an initial skeleton of a PRN (mapping from an initial FD), identifies the cause-effect relationships within the SDM by neural learning, and then converts it back to the corresponding FD. The composite approach makes model construction simpler and more systematic.
