  • Publication number: 20210219399
    Abstract: A method for controlling an amount of power delivered to an electrical load may include controlling an average magnitude of a load current towards a target load current that ranges from a maximum-rated current to a minimum-rated current in a normal mode, and controlling the average magnitude of the load current below the minimum-rated current in a burst mode. The burst mode may include at least one burst-mode period that comprises a first time period associated with an active state and a second time period associated with an inactive state. During the burst mode, the method may include regulating a peak magnitude of the load current towards the minimum-rated current during the active state, and stopping the generation of at least one drive signal during the inactive state to control the average magnitude of the load current to be less than the minimum-rated current.

  • Publication number: 20210014954
    Abstract: Provided herein are examples of a remote control device that provides a retrofit solution for an existing switched control system. The remote control device may comprise a control circuit, a rotatable portion, a magnetic ring coupled to the rotatable portion, and first and second Hall-effect sensor circuits configured to generate respective first and second sensor control signals in response to magnetic fields generated by the magnetic elements. The control circuit may operate in a normal mode when the rotatable portion is being rotated, and in a reduced-power mode when the rotatable portion is not being rotated. The control circuit may disable the second Hall-effect sensor circuit in the reduced-power mode. The control circuit may detect movement of the rotatable portion in response to the first sensor control signal in the reduced-power mode and enable the second Hall-effect sensor circuit in response to detecting movement of the rotatable portion.

  • Publication number: 20200403877
    Abstract: A control device may be configured to delay an attachment procedure while attachment messages are being transmitted over the network. The control device may be configured to initiate an attachment procedure with a router device on a network at the end a back-off period of time. The attachment procedure may include transmitting attachment messages (e.g., parent request messages) that enable the control device to transmit and receive messages over the network through the router device. During the back-off period of time, the control device may determine an attachment message is received from another control device on the network. And, if an attachment message (e.g., a parent request messages and/or a link request message) is received from another control device, the control device may increase the back-off period of time (e.g., delaying when the control device initiates its attachment procedure).

  • Publication number: 20200403866
    Abstract: A control device may be configured to form a network at a unique coordinated startup time. The control device may identify a role assigned to the control device in a previously-formed network that the control device was attached to. The control device may determine a unique coordinated startup time for the control device based on the role assigned to the control device in the previously-formed network. The control device may initiate a network formation procedure at the unique coordinated startup time for the device. For example, the network formation procedure may cause the control device to attach to another control device in the network. The network formation procedure is configured to enable the control device to assume the role assigned to the control device in the previously-formed network in the new network.

  • Publication number: 20200404513
    Abstract: A control device may communicate messages with devices in a network through a parent device, and receive messages from auxiliary parent devices. The control device may store a respective communication metric associated with each of the parent device and the one or more auxiliary parent devices. The control device may set an auxiliary parent device of the one or more auxiliary parent devices as the parent device of the control device, e.g., when a respective communication metric of the auxiliary parent device determined to be set as the parent device indicates a stronger communication link than the parent device. The control device may determine that the respective communication metric of the auxiliary parent device indicates a stronger potential communication link than the parent device when the average received signal strength indicator of auxiliary parent device is greater than the average received signal strength indicator of the parent device.

  • Patent number: 9538600
    Abstract: A load control device for controlling the amount of power delivered to an electrical load is able to operate in a burst mode to adjust the amount of power delivered to the electrical load to low levels. The load control device comprises a control circuit that operates in a normal mode to regulate an average magnitude of a load current conducted through the load to a target load current that ranges from a maximum rated current to a minimum rated current. The control circuit operates in the burst mode to regulate the average magnitude of the load current below the minimum rated current. During the burst mode, the control circuit regulates a peak magnitude of the load current to the minimum rated current during a first time period, and stops regulating the load current during a second time period, such that the average magnitude of the load current is below the minimum rated current.
