摘要： One embodiment of the invention employs techniques for the self-installation of network devices using fire-and-forget principles. These devices modify their own network configuration data, but do not modify the network configuration data of other devices. Utilizing fire-and-forget principles, the need for a central database and central authority on the network is not required but may still be used.

摘要： A transmitting box (101) is connected to a first electrical outlet in a building. The phase of the first electrical outlet is used as the reference phase. The transmitter box senses each of the zero-cross-overs of the reference phase and injects a data packet of the data carrier frequency at each zero-cross-over. A receiving box (103) is connected to a second electrical outlet in the building. The second electrical outlet has a test phase which may be different from the reference phase. The receiver box receives each data packet and senses each phase zero-cross-over of the test phase. The receiver box uses the time between each reception of a data packet and each detection of a test phase zero-cross-over to determine the phase angle of the test phase relative to the reference phase.

摘要： A power line communications amplifier includes a first amplifier (23) which amplifies a transmit signal consistent within a first operating potential range, a second amplifier (52, 59, 61) which provides additional amplification of the transmit signal consistent within a second operating potential range, wherein the second range is larger than the first range, and a transformer (90) which is employed to couple the amplifier transmit signal output by the second amplifier (52, 59, 61) to the power line communications system. A feedback circuit (70, 71, 72) couples the output of the second amplifier (52, 59, 61) to the input of the first amplifier (23) and functions to maintain a low output impedance while the amplifier circuit operates in a transmit mode. Control circuit (14, 40) is coupled to the second amplifier (52, 59, 61) for switching the amplifier circuit from the transmit mode to a receive mode. While in the receive mode, the amplifier circuit presents a relatively high output impedance.

摘要： An apparatus for reducing power line communication signal attenuation is disclosed. This apparatus provides for reduction of power line communication signal attenuation by balancing reactance between the chosen circuit elements (70, 72, 74) and the typical impedances found in a house (100), a structure, or vehicle.

摘要： A sigma-delta A/D converter (301) having a digital logic gate core. The converter is comprised of a loop filter (304) for shaping the converter's quantization noise spectrum. The loop filter is comprised of an unbuffered CMOS logic gate inverter (602) which can be implemented by a gate array. A quantizer (305) is coupled to the loop filter. A logic gate buffer (501) is configured as a one-bit comparator, which is used to perform the quantization. This logic gate buffer can be one of the gates of a gate array. A sample (306) is coupled to the quantizer for sampling the quantized signal. This sampler can also be implemented by digital circuitry of a gate array. The signal from the sampler is fed into a decimator (302). The decimator outputs a digital signal representative of the amplitude of the analog signal.

摘要： An improved apparatus and method for communicating information in a networked system wherein variables are employed to accomplish such communication. Network variables allow for standarized communication of data between nodes (301-305) in a network. A first node (301) may be programmed, for example, to sense certain information and to report the information as a network variable X. A second node (302) may be programmed to receive the variable X and to control devices based on the current value of the variable. The present invention provides for defining connections (201) between the first and second node to facilitate such communication and for determining addressing information to allow for addressing of messages, including updates to the value of the variable X, between the nodes.

摘要： A network connection point (214) cannot be added to a first network connection (1) when it already belongs to a second network connection (2). When a particular configuration would otherwise violate this rule, a network connection point (600) on the node is established as an alias to the network connection point. The alias network connection point (600) is added to the first network connection (1). A correlation is established between the alias network connection point (600) and the network variable that is associated with the network connection point (214). The correlation between the alias network connection point (600) and the network variable may be established through tables (700, 702, 704) in the apparatus.

摘要： A transceiver module (40) for coupling between cells (27) in a distributed intelligence network and a twisted pair line (23). The module receives power from the line and provides power to its respective cell. At the end of transmitting a packet, the transceiver transmits a code violation, then an anti-code violation to dissipate energy in the line. This is followed by clamping the line for the dead time between packets (fig. 7). N transceivers may be connected (without a cell) to form a repeater (fig. 5). The transceiver module may be used in a network having free topology; that is, an ideal transmission line with terminators is not needed.
