摘要:
According to one embodiment, an electronic apparatus has an established wireless connection with a first apparatus. The electronic apparatus includes a capacitor (26, 28) charged by a commercial power source, a first transmitter (412) configured to transmit information related to a power failure to the first apparatus when detecting the power failure, and a second transmitter (422) configured to establish a wireless connection with a wirelessly-unconnected second apparatus when detecting the power failure and to transmit the information related to the power failure to the second apparatus. The first and second transmitters are configured to be driven by a charge of the capacitor during the power failure.

摘要:
A method of accounting for electrical power contribution and consumption is presented. The method comprises receiving information, from a plurality of facilities, wherein the plurality of facilities is operable to generate and/or consume electricity, and wherein the data comprises information concerning electricity contributions to a power grid, and/or consumptions from the grid by the plurality of facilities. The method further comprises applying a robust system of cryptographic processes to said information concerning electricity contributions, and attest to the authenticity of the information, as well as to the correct attribution of the facility claimed. Finally, the method comprises tracking and accounting electricity contributions and/or consumptions from each of the plurality of facilities using decrypted and verified information in a manner that allows contributions to be independently verified through audits. The method can also comprise compensating each of the facilities based on the respective electricity contribution and/or consumption of each facility.

摘要:
The invention relates in particular to an integrated device for the adaptation of fluid metering devices, comprising an attachment means for attachment to the meter, a pulse generating means for generating electrical pulses at a rate dependent on the volume of fluid used, means for counting and storing the number of pulses generated during a particular time period, and communication means for communicating the stored pulse readings. Ideally these elements are integrated into a single housing, attachable to a meter by simply plugging thereto, without the need for any programming.
