Abstract: In a shade system with a bracket supporting a shade storage roll, an anti-reversible power spring apparatus includes a biasing member and a housing with a receiver end and a connector end where the housing encloses the biasing member and the receiver end and the connector end contain the biasing member within the housing. A connector device is connected with the housing and a receiver device is connected with the housing where the connector is connectable with a receiver and where the receiver is connectable with a connector.

Abstract: In a shade system with a bracket supporting a shade storage roll, an anti-reversible power spring apparatus includes at least one biasing system connected with the storage roll wherein the biasing system includes a biasing member with a first end and a second end wherein the first end moves with the storage roll as the storage roll rotates and wherein the second end is held stationary with reference to the storage roll when the storage roll rotates in one direction but not when the storage roll rotates in a second direction. A support for the at least one biasing system is provided wherein the support includes a protrusion that holds the second end against movement when the storage roll is rotated in the one direction but which allows passage of the second end past the protrusion when the storage roll is rotated in the second direction.

Abstract: A movable assembly having a counterbalance gear tensioner includes a covering, a rotatable storage roll with a hollow interior that carries the covering, and a counterbalance assembly that is received in the hollow interior to assist in movement of the covering. A gear tensioner is also received in the hollow interior, rotates with the rotatable storage roll, and is coupled to the counterbalance assembly to adjust a tension force of the counterbalance assembly.

Abstract: A curtain assembly comprises a rotatable drive element wherein at least one helical guide structure is formed on, or into, the outer surface of the drive element. A drive attachment element having a structure that communicates with the helical guide structure to move the drive attachment element axially along the drive element when the drive element is rotated. Specific embodiments incorporate either a manual or motor-driven rotation assembly for rotating the drive element. Further specific embodiments involve a helical guide structure that comprises a helical groove and a structure that comprises a tooth that engages with the helical groove.

Abstract: A network operator radio module (NORM) configured to be removably attached to a barrier operator comprises a transmitting antenna, a receiving antenna, a transceiver antenna, and a microcontroller. The module communicates with a communication network that comprises various nodes configured by a network controller module and a network communication module. Each node may be associated with a network appliance, and may be remotely controlled by sending a suitable function code to the module via local command signals. Furthermore, various local remote transmitters and keyless entry transmitters are configured to transmit function codes to control the module and the associated various network appliances.
