Methods and systems for managing power consumption of network devices are disclosed. An example method can comprise detecting a triggering condition and reducing functionality of a network device based on detecting the triggering condition. The method can comprise detecting, at the network device, a user device, restoring functionality of the network device in response to detecting the user device, and transmitting information to the user device after restoring functionality of the network device.

Sensors within sensor node networks may communicate bio-event or other types of measurement results/decisions between each other using signal transmission variations. Each sensor node within a network and between networks may transmit and receive signals. A sensor node may scale a signal transmission power in a manner that is proportional to a confidence level of a decision or measurement about an event being detected. Each sensor node will receive transmissions from neighboring nodes, and can refine an estimate about an occurrence of the event at its location based on received signal strengths, for example.

A cloud based system receives multiple types of security telemetry from multiple participating organizations. The received security telemetry can be pseudonymized by replacing fields containing sensitive information with corresponding pseudonyms. Two data stores can be maintained, a first for raw telemetry, and a second for pseudonymized telemetry. Each data store can comprise a directory structure organized according to factors such as originating organization, administrative unit, telemetry type, schema, format and/or version and receipt time. Raw telemetry is stored in directories of the first data store, and pseudonymized security telemetry is stored in directories of the second data store, both organized according to the above-described factors. Analytics of the telemetry is facilitated by providing controlled access to analytics clients, according to permissions granted by the originating organizations and declared requirements of the analytics clients, at levels of granularity based on the above described factors and pseudonymization status.

A system including a transceiver that is in a first device and receives wirelessly or over a powerline and from a second device, (i) a voltage value of a voltage detected between bus bars of a power source, where the power source supplies power to a load, and where the load is distinct from the first and second devices, or (ii) a current value of a current detected by a current sensor and drawn from the power source by the load. A sensing module one of (i) if the transceiver receives the current, detects the voltage and timestamps the voltage value with a first timestamp, and (ii) if the transceiver receives the voltage, determines the current and timestamps the current value with a second timestamp. A parameter module determines a parameter of the load based on the voltage, the current, and the first and second timestamps.

Techniques are discussed for performing a demand reset in a wireless meter reading environment, in a manner such that demand data may not be lost. In response to receiving a command from a mobile device of a requester, a meter may store demand value(s) in a log, reset register(s) that store the demand value(s) and wirelessly provide the demand value(s) to the mobile device of the requester. Due to the lack of reliability associated with wireless communications between the meter and a requestor, the requestor may not actually receive the demand value(s). Upon receiving a subsequent command for the demand value(s), the meter may determine that the command is a replay, and provide the demand value(s) without resetting the register(s). Techniques are also discussed for generating the commands, securing the commands, and providing the commands to mobile devices in route packages.

A visual light communication emitter for a vehicle, arranged to communicate a status of the vehicle, includes a first light emitter arranged to emit flash light which is modulated at a first target frequency in a dedicated non-visible spectrum, and a second light emitter arranged to emit flash light which is modulated at a second target frequency in the dedicated non-visible spectrum. A difference between the first target frequency and the second target frequency is predetermined, so as to authenticate the status of the vehicle.

A utility meter includes a metrology core, a short-range radio configured to communicate wirelessly over a local area mesh network, a long-range radio configured to communicate wirelessly over a wide area network and a controller that checks a performance of the local area mesh network against one or more predetermined performance criteria. When the performance of the local area mesh network meets a set of one or more predetermined performance criteria, the utility meter communicates a first set of the information to the head-end system using the short-range radio. When the performance of the local area mesh network does not meet the set of one or more predetermined performance criteria, the utility meter communicates a second set of information to the head-end system using the long-range radio.

A visual light communication emitter for a vehicle, arranged to communicate a status of the vehicle, includes a first light emitter arranged to emit flash light which is modulated at a first target frequency in a dedicated non-visible spectrum, and a second light emitter arranged to emit flash light which is modulated at a second target frequency in the dedicated non-visible spectrum. A difference between the first target frequency and the second target frequency is predetermined, so as to authenticate the status of the vehicle.
