Abstract: A battery-powered node includes a primary cell, a secondary cell, and a battery controller. The battery controller includes a current source that draws power from the primary cell to charge the secondary cell. The battery-powered node draws power from the secondary cell across a wide range of current levels. When the voltage of the secondary cell drops beneath a minimum voltage level, the current source charges the secondary cell at a constant current level and a charging signal is sent to the battery-powered node. When the voltage of the second cell exceeds a maximum voltage level, the current source stops charging the secondary cell and the charging signal is terminated. The battery-powered node records the amount of time the charging signal is active, which can be used to determine a battery depletion level for the primary cell. Battery replacement may then be efficiently scheduled based on the depletion level.

Abstract: A central controller is configured to obtain a scan of a quick response (QR) code affixed to an internet-of-things (IoT) device. The central controller decodes the QR code to extract various operating parameters associated with the IoT device. The central controller then provisions a device controller for coordinating operation of the IoT device. The central controller configures the device controller based on the operating parameters, thereby allowing the device controller to coordinate operations of the IoT device in a device-specific manner. The central controller may then install the device controller on the IoT device, or cause the device controller to coordinate IoT device operations across a network. With this approach, a technician is no longer required to manually obtain IoT device operating parameters or input those parameters to a central controller, thereby streamlining the IoT device installation process.

Abstract: A battery controller buffers a higher voltage provided by a primary cell in order to charge a secondary cell that operates at a lower voltage. The battery controller includes a storage device that is charged by the primary cell. When the voltage of the storage device reaches a threshold, the battery controller conducts the stored charge into the secondary cell while isolating the secondary cell from the primary cell. The secondary cell, when charged, powers a node that operates with a low voltage.

Abstract: A node in network is configured to buffer data received from other nodes across multiple channels. The node process a portion of the buffered data associated with a subset of those channels. When the node receives data on that subset of channels that includes a notification, the node then processes a larger portion of the buffered data associated with a larger number of channels. In doing so, the node may identify additional notifications include within data that was buffered but not previously processed. The node may also coordinate with other nodes in order to process buffered data upon identification of a notification.

Abstract: A communications device has a first communications port via which secure messages are received, and a second communications port via which non-secure messages are received. In response to detecting that a secure message has been received, the device determines whether the second communications port is in a state that enables non-secure messages to be received. If the second communications port is in the enabled state, the device autonomously disables the second communications port to preclude non-secure messages received at that port from being processed.

Abstract: A network node (MR/BR node) is configured as a mesh router node in a first wireless network comprised of a plurality of first nodes and as a border router node in a second wireless network comprised of a plurality of second nodes, the second wireless network distinct from the first wireless network. The MR/BR node has a unique first address in the first wireless network and a unique second address in the second wireless network. In this way, the MR/BR node can receive a first communication in the first wireless network via the first address, and transmit the received first communication to at least one of the second nodes in the second wireless network. The MR/BR node can also receive a second communication in the second wireless network via the second address, and transmit the received second communication to at least one of the first nodes in the first wireless network.
