摘要:
An apparatus in an example comprises an integrated circuit and one or more resistors. The integrated circuit comprises an internal current source and an external interface pin. The one or more resistors arc external to the integrated circuit and coupled with the external interface pin of the integrated circuit. Application of current from the internal current source of the integrated circuit to the one or more resistors through the external interface pin serves to generate a voltage that is employed to identify the integrated circuit.

A method and system for estimating energy consumption of a utility population includes organizing the utility population comprising energy consumers into a plurality of groups. Next, a distribution of energy consumption against the plurality of groups may be calculated. Subsequently, statistically representative groups based on the energy distribution and the plurality of groups may be determined. Data is then collected from the statistically representative groups at predefined intervals from a communications network. Energy consumption of the utility population may then be estimated based on the data collected from the statistically representative groups. The communications network comprises an advanced metering infrastructure (AMI) network.

A method and system provide for the cooperative charging of electric vehicles. By using power line communications, chargers of the electric vehicles who are serviced by the same distribution transformer can form self-contained local area networks due to the nature of power line communications (PLCs). Alternatively, or in addition to the PLCs, other communication networks, such as the Internet and local area networks, may be used as part of the communications infrastructure for the chargers. After the chargers of the electric vehicles are coupled to one another through power line communications or traditional communications networks, they can form a logical token ring network. According to this token ring network, a predetermined number of tokens can be assigned within the token ring network for permitting chargers with tokens to charge respective electric vehicles while chargers without tokens must wait until they receive a token to initiate charging.

The invention is directed to compositions and methods for selectively reducing the expression of a gene product from a desired target gene in a cell, as well as for treating diseases caused by the expression of the gene. More particularly, the invention is directed to compositions that contain double stranded RNA (“dsRNA”), and methods for preparing them, that are capable of reducing the expression of target genes in eukaryotic cells. The dsRNA has a first oligonucleotide sequence that is between 25 and about 30 nucleotides in length and a second oligonucleotide sequence that anneals to the first sequence under biological conditions. In addition, a region of one of the sequences of the dsRNA having a sequence length of at least 19 nucleotides is sufficiently complementary to a nucleotide sequence of the RNA produced from the target gene to trigger the destruction of the target RNA by the RNAi machinery.

A system for communicating across conventional HVAC wiring is provided. The system includes a communication device having a communication module capable of inducing low power, high frequency current signals into a single control wire coupling, for example, a thermostat with a compressor. The communication module includes a power supply module that draws power sufficient to operate the communication module from the existing HVAC wiring, so as to eliminate any need for batteries or external power sources. A second communication module may be coupled to the single control wire. The second communication module operates as a transceiver sending communication signals to, and receiving communication signals from, the communication module. In one embodiment, the communication module is disposed within a building, for example coupled to an electronic thermostat, while the second communication module is disposed outside the building near the compressor. The communication signals are RF modulated signals between 5 and 50 MHz so as to take advantage of and pass across parasitic capacitances found inherent in transformers or other coils disposed within HVAC loads.

A method and system for shedding loads based upon a power system characteristic, such as voltage or frequency, is provided. In one embodiment, a remote party, such as a power generator or utility, transmits a signal to a control device proximately located with a load device. Upon receipt of the signal, the control device measures the power system characteristic for a predetermined time to establish a baseline threshold. The control device then monitors the power system characteristic. When the power system characteristic falls outside the baseline threshold, the control device sheds load. In one embodiment, the loads are prioritized such that the load of least importance may be shed first.
