A method and system for using smart bulbs is disclosed. One aspect of certain embodiments includes providing applications to both the consumer and the utility to monitor and control the bulbs and provide an audit trail.

Smart bulb system

A method and apparatus for error avoidance in data transmission using dynamic modification of sampling rates. An embodiment of a method for transmission of data includes determining the transmission capacity for a transmission channel or channels. A sampling rate is selected based at least in part on the determined transmission capacity for the one or more transmission channels. An instruction, command, or information regarding the sampling rate is inserted in a data packet, and the data packet is transmitted.

Error avoidance in data transmission using dynamic modification of analog sampling rates

A method and apparatus for error masking for data transmission using received data. An embodiment of a method includes receiving a first data packet, where the first data packet contains multiple data elements, the first data packet being a data packet in a data stream. The method further includes determining that one or more data packets are missing from the data stream, and generating one or more data packets to replace the one or more missing data packets based at least in part on the one or more data elements of the first data packet.

Error masking for data transmission using received data

Apparatuses and methods are disclosed for communications using current detection. According to one embodiment, a transmitter generates a signal on a transmission line by switching between two power sources. According to one embodiment, the transmitted signal is a balanced signal. Under an embodiment, a signal that has been transmitted on the transmission line is received by a receiver that includes a current detector, and the receiver detects the signal by sensing changes in current on the transmission line. According to one embodiment, the current detector includes a sensor that senses changes in the magnetic field generated by changes in current in the transmission line.

Communication with current detection

A method and system for transmitting data over loaded twisted pair copper wires using a low frequency offset, differential voltage, on-off keying (OOK) transmission technique are described. According to one embodiment, an analog or digital signal is sent or received and converted, if necessary, into or from serial format onto or out of a loaded twisted pair copper wire. The signal uses an OOK modulated sinusoidal offset signal with an associated differential voltage. A floating reference ground set positive or negative for the differential nature of the transmission may be required. The OOK modulated offset low frequency is being keyed to the floating ground reference that is set to a minimum signal to noise ratio (SNR) level. The SNR level may be set by adjusting the voltage separation between floating ground and the offset of the sinusoidal low frequency wave. The amplitude of the sinusoidal wave may be adjusted to provide increased transmission distance and better SNR. In addition, an encoding scheme may be used to incorporate all signaling and control information within the serial transmission.

A method and system for transmitting data over twisted pair copper wires using a low frequency offset, differential voltage, on-off keying (OOK) transmission technique are described. According to one embodiment, an analog or digital signal is sent or received and converted, if necessary, into or from serial format onto or out of a twisted pair. The signal uses an OOK modulated sinusoidal offset signal with an associated differential voltage. A floating reference ground set positive or negative for the differential nature of the transmission may be required. The OOK modulated offset low frequency is being keyed to the floating ground reference that is set to a minimum signal to noise ratio (SNR) level. The SNR level may be set by adjusting the voltage separation between floating ground and the offset of the sinusoidal low frequency wave. The amplitude of the sinusoidal wave may be adjusted to provide increased transmission distance and better SNR. In addition, an encoding scheme may be used to incorporate all signaling and control information within the serial transmission. Next, the transmitted signal is input into a coupler that interfaces it to the twisted pair network. At the far end, a decoupler receives the transmission and sends the OOK sinusoidal signal out to designated amplifiers to provide voltages needed for activating an OOK detection system. The OOK detection system may use current detection that is activated every time the designated OOK signal frequency is received. Clocking may be recovered using a digital phase lock loop. Further, the OOK signal is decoded and information split off to designated leads. Afterwards, the recreated square wave transmission serial bit stream is converted to compatible signaling voltages and sent to a digital computer interface.

According to one embodiment, an analog or digital signal is sent or received and converted, if necessary, into or from serial format onto or out of a power line. This signal is an OOK modulated sinusoidal offset signal with an associated differential voltage. Next, the transmitted signal is input into an additive coupler which serves as an interface to the power-line network. At the far end, an additive decoupler receives the transmission and sends the frequency out to the designated amplifiers to provide the needed voltages to activate the OOK detection system. This system uses current detection that is activated every time the designated OOK signal frequency is received. Further, the OOK signal is decoded and information split off to the designated leads. Afterwards, the recreated square wave transmission serial bit stream is converted to compatible signaling voltages and sent to the digital computer interface.
