  • Patent number: 9743497
    Abstract: A wireless load control system is provided including one or more wireless switch components and one or more load controller components optionally in one-to-one, many-to-many, many-to-one, and one-to-many wireless communication with each other. A wirelessly-controlled load controller assembly includes an enclosure adapted to fit within a junction box, the enclosure comprising a projecting fitting adapted to fit through an aperture of the junction box to maintain the enclosure in fixed relation to the junction box. A control circuit in the enclosure is provided with an antenna that extends through an antenna port that is disposed within the fitting so that when the load controller is mounted in a junction box, the antenna extends through the aperture of the junction box.

  • Patent number: 9401252
    Abstract: A wireless load control system is provided including one or more wireless switch components and one or more load controller components optionally in one-to-one, many-to-many, many-to-one, and one-to-many wireless communication with each other. A wireless switch assembly includes a base and a corresponding rocker shell that together define an enclosure for a control circuit and at least one elastically deformable actuator, the actuator being movable between an engaged position and a disengaged position.

  • Patent number: 9268488
    Abstract: A memory life extension system and method is provided for managing operation of rewritable memory used to store a monotonically increasing sequence of multiple-byte binary values in a set of one or more memory locations in the rewritable memory. A first value is read in from a set of one or more memory locations. On detection of an instruction to store an incremented value, the incremented value is permuted by applying an encoding, in which a value of a least significant bit changes only on every second increment, to two least significant bits of the incremented value. On overflow of a least significant byte as a result of the increment, a cyclic byte-wise shift is applied to the incremented value. The permuted incremented value is then stored in the one or more memory locations.
