Described is a communication link establishment method. The method includes transmitting, by a diagnostic tool, a wireless wake signal on a wake wireless channel to a low-power endpoint in a metrology mesh network. The wake wireless channel is selected using a unique identifier of the battery-operated endpoint. The method also includes receiving, at the diagnostic tool, a confirmation message from the low-power endpoint that the wireless wake signal was received at the low-power endpoint. Additionally, the method includes establishing, by the diagnostic tool, a communication link between the diagnostic tool and the low-power endpoint at a wireless communication channel different from the wake wireless channel. Further, the method includes performing, by the diagnostic tool, a diagnostic operation on the low-power endpoint.

In a general aspect, motion is detected using wireless signals. In an example, a method includes receiving, at a wireless communication device, requests for the wireless communication device to transmit wireless signals, the requests initiated by a wireless sensing system. The method further includes transmitting a series of wireless signals from the wireless communication device in response to the requests, and detecting, at the wireless communication device, a trigger event after transmitting the series of wireless signals. The method additionally includes updating, by the wireless communication device, a state of the wireless communication device based on the trigger event, the updated state indicating that the wireless communication device is not enabled to transmit wireless signals in response to the requests from the wireless sensing system. The method also includes communicating, by the wireless communication device, the updated state of the wireless communication device to the wireless sensing system.

In some aspects, a system is provided that includes a plurality of communication nodes configured in a wireless mesh network or a low-power wireless network and a sensor assigned to a monitored subject. The sensor includes a first wireless network interface, for a first wireless network, adapted to communicate with the wireless mesh network or the low-power wireless network and a second wireless network interface, for a second wireless network, adapted to communicate with a mobile device. The sensor includes one or more processors adapted to receive, via the first wireless network, an indicator to transmit an identification message to the mobile device and, based on receiving the indicator, transmit, via the second wireless network, the identification message to the mobile device.

An example module includes: a radio to communicate with a sensor; a communication interface to communicate with a second module; a chassis to mate with the second module; and a processor connected to the radio, the communication interface, and a memory, the processor to execute instructions stored in the memory. The instructions are to: receive, via the radio, sensor data from the sensor; process the sensor data to generate processed sensor data; and transmit the processed sensor data to a remote device.

System and method for collection, control and wireless transmission of environmental and other data. Nodes may wirelessly connect to other nodes to relay node specific information, collected sensor data or commands to and from other nodes and gateway nodes linked to a central database. Nodes in gateway mode may be capable of aggregating and relaying commands and data between other nodes and a centralized database. Nodes may bypass other nodes and/or gateway nodes and communicate directly with the central database via satellite or cellular link. Nodes may be self-contained devices, inclusive of a wind or solar power source and a battery, eliminating the need for an external power source. Nodes may be configured independently or as a system to monitor and control various types of equipment including utility lines or water systems or used to collect environmental data. Nodes may communicate on different channels/frequencies based on systematic or pseudo-random changes.

Detachable Internet of Things (IoT) modules can be coupled to products such as home appliances to create an IoT environment or ecosystem. The detachable IoT module includes a communication module insertable into a groove formed about an exterior surface of a home appliance and electrically connected with a controller in the home appliance, and a sensor module coupled to the communication module and electrically connected with the controller through the communication module, the sensor module capable of measuring an air state near the home appliance, where the sensor module and the home appliance are in wireless communication with an external terminal through the communication module.

An improved system and method for detecting smoke using a sensor is disclosed. The method can comprise the steps of storing in memory a plurality of smoke signatures, wherein each of the smoke signatures relates to how the sensor senses one of a plurality of particulates, each of the plurality of particulates indicative or non-indicative of a fire, and receiving current data from the sensor. Moreover, the method can comprise the steps of comparing the current data with the plurality of smoke signatures to determine if the current data matches any of the plurality of smoke signatures, and initiating an alarm sequence based at least in part on a determination as to whether the current data matches a smoke signature related to a fire-indicative particulate of the plurality of particulates.

Systems, methods, and computer-readable storage media for dynamically adjusting nodes in a mesh network embedded in objects. The nodes, which are individually capable of sensing and/or transmitting data, are paired together such that when one node is active, the other node is collecting energy via solar, wind, or other energy collecting means. When a node reaches a certain energy level, the nodes can switch status, such that the passive node becomes active and vice versa. Exemplary objects in which the systems can be embedded include benches, receptacles, and light fixtures.

An information generation device comprises a processor that acquires sensor information indicating a measurement result of a detection target area from each of a plurality of sensors having the detection target area that is common to the plurality of sensors, that determines whether or not each of the plurality of sensors detects an object existing in the same predetermined area on the basis of a plurality of pieces of the sensor information acquired, and that generates first display information for separately displaying the object that is detected by each of the plurality of sensors in a case where a determination result is positive and a predetermined condition for determining whether or not a plurality of the objects detected by the plurality of sensors are the same object is not satisfied, and generates second display information for displaying the object detected by each of the plurality of sensors in a display style different from a display style of the first display information in a case where the determination result is positive and the predetermined condition is satisfied.
