摘要： Systems and methods are provided for reducing network traffic in a mesh network by reducing the number of status messages communicated over the network. The nodes of the network can provide status information to a gateway based on each node's distance from the gateway. The closer nodes respond to the request from the gateway first and then the farther nodes respond to the request. When a node is ready to transmit a status message with status information to the gateway, the node sends the message to the nodes in communication with the transmitting node. One of the closer nodes that receives the message then forwards the message to additional nodes in communication with the forwarding node, while the other nodes that received the message do not forward the message. The process of forwarding messages by a single closer node is repeated until the status information is received by the gateway.

摘要： To speed up a firmware update process, a gateway performs an expedited topological discovery of networked nodes. The gateway maintains a list of unlinked network nodes that are not known to share good edges with other nodes. The gateway transmits a topology query to a selected unlinked node, which the node retransmits to its neighboring nodes. Each neighboring node responds to the gateway with a link status of the edge between the queried node and the neighbor. The queried node and each neighboring node with an edge of sufficient link quality are removed from the list of unlinked nodes. The process is repeated until no networked nodes remain in the list of unlinked nodes. The gateway then sends a firmware update to nodes that will in turn retransmit the update over identified good edges.

摘要： An indoor air quality control system may be implemented to control a plurality of air handling units within an industrial facility in a concerted effort to effect an overall air quality goal. A remote server analyzes sensor data, historical data, and other environmental data (e.g., predicted weather data), and uses one or more machine learning algorithms to model the behavior of air within the facility. The sensed air quality data is considered holistically to understand the overall condition of the facility and the gradient of air flows and/or contaminant flows within the 3-dimensional space. Air handling models are applied to current sensor data to generate instructions to selectively turn on/off or otherwise control components of various air handling equipment to reach an optimized air quality result. Decisions on how to control the facility are based on environmental health and safety considerations.

摘要： A system for a tag includes a network controller that, when it has information to send to a tag, is configured to communicate with the tag's neighbors, such as anchors that may be used for communication between the tag and the network controller. In this regard, the network controller may instruct the tag's neighbors to stun the tag upon hearing from the tag. Thus, when the tag transitions out of a sleep state and transmits a status message or other type of message to the network controller or other resource of the network, at least one neighbor of the tag hears the message and, in response, stuns the tag so that it remains awake for a longer period of time, thereby giving the network controller sufficient time to send control information or other information to the tag. Since the neighbors are responsible for stunning the tag, the amount of time required to stun the tag after it awakens from the sleep state is decreased.

The combiner element is configured to receive and combine current from the solar power arrays thereby providing a combined current signal that is based on current from each of the solar power arrays. The combiner element has a current sensing element coupled to one of the solar power arrays and is configured to receive current from the one solar power array. The current sensing element also has a sensor configured to sense a magnetic flux induced by the current from the one solar power array, and the sensor is configured to transmit data indicative of the sensed magnetic flux. The current sensing element further has a magnetic core and a conductive coil for carrying the current from the one solar power array.

摘要： Lights may be misconfigured during installation or after they are installed in a facility, such that these lights, also known as orphaned nodes, cannot receive control messages sent by a lighting control system. After installation, a mobile device can be used to identify the network a particular light source is communicating on, by use of a photodetector that detects, in the visible light signal emitted by a light source, data representing the network ID used by the light source. The mobile device can determine from that data whether or not the light source is communicating over the wrong network. If it is determined that a light source is on the wrong network, and therefore orphaned, the mobile device can switch its own configuration so as to be able to communicate to the orphaned light source, and provide instructions to reconfigure the light source to use a corrected network ID.

摘要： A wireless network can perform a topological mapping through its gateway, which sends a multicast message over the wireless network to every node of a network. Each of the nodes on the network, on receipt of the multicast message, can transmit a one-hop multicast message containing a topological ping to its neighboring nodes. A neighboring node receiving a topological ping will store information relating to the link quality between the sender and neighboring nodes. After network traffic related to the topology discovery has quieted, the neighboring nodes sends the stored information to the gateway, without any processing by the node which sent the topological ping. All nodes may also implement a randomized delay both before sending the topological ping, and/or before sending the stored information to the gateway, to minimize the opportunity for data collision of messages relating to topological discovery.

摘要： A switching circuit with switches between a charging path and a low-impedance active path. The charging path comprises a zener diode substantially in parallel with a charging capacitor. Current flows through the charging path when the circuit is powered on and a power supply charges the charging capacitor while current flows through the charging path. The low-impedance bypass path comprises a switch that remains closed until a voltage across the charging capacitor exceeds a threshold voltage. The switch opens when the charging capacitor exceeds the threshold voltage.

摘要： Systems and methods are provided for reducing network traffic in a lighting system. A server computer can calculate the energy consumption of the light sources in the lighting system based on the settings of the lights sources implemented by the server computer and power usage data for the light sources. By calculating the energy consumption at the server computer based on the implemented settings and the power usage data, the server computer does not have to receive communications from the controllers of the light sources indicating the power usage or energy consumption of the light source. The power usage data for the light sources can be updated to enable the server computer to provide more accurate energy consumption information for the lighting system.

摘要： An asset tracking system has a plurality of anchors. A tag communicates with the anchors as it is moved by a user being tracked by the system, and data based on communication between the tag and at least one of the anchors is transmitted to a server. The server determines a location of the tag based on the data and detects an occurrence of an event based on the location. The server also transmits to each of the anchors a tag alert message having a tag identifier identifying the tag and an event indicator associated with the occurrence of the event. At least one of the anchors transmits the tag identifier and the event indicator to the tag, which issues a warning to the user in response to tag alert message.
