摘要： Methods and systems are disclosed for applying an interleaver that better distributes signal errors to be used in devices operating on low voltage power grids. One embodiment of a method comprises: determining a frequency cycle of the communication medium; setting an interleaver block size based on the frequency cycle of the communication medium; re-arranging bits in a data packet based on the interleaver block size; transmitting the re-arranged data packet over the communication medium to a receiver. Specifically, according to an embodiment, the interleaver block size is set to one-half of the frequency cycle of the communication medium.

摘要： The combination of LED lighting and particulate detectors are enhanced by exploiting the light degradation/reflection/wavelengths detected, absorbed or frequency shift seen in lighting due to the presence of smoke, gas or other molecules (such as explosives) in the air can be detected. The use of LEDs is expanded well beyond simple lighting and energy savings to include not only smoke and fire detection by also to scan for gases and particulates found based in the usage environment.

摘要： A method implemented in a device is disclosed for networking through signals transmitted across a shared medium network. The method starts with monitoring for a first signal on a shared medium of the shared medium network. The first signal is processed after it is received and while the first signal is being processed, a set of one or more signals is received on the shared medium. Then a set of one or more amplitude increases is determined, where each amplitude increase is from an earlier received signal to a later received signal. The set of one or more amplitude increases is compared to a threshold value and at least partially in response to the comparison, the device discards one or more signals from the first signal and the set of one or more signals.

摘要： A method is disclosed for detecting packet at a receiving system in a Multi-Carrier Modulation (MCM) system. The method starts with receiving a signal at the receiving system. Then during the plurality of symbol durations, a set of phases of the signal for each symbol duration is obtained, where each phase is a phase of a carrier of the number of carriers. Then a set of phase variances for each carrier of the number of carriers is obtained, where each phase variance is a difference of phases of a carrier in different symbol durations. Then a phase variance value based on the set of phase variances is computed and it is compared with a threshold to determine whether a packet has been detected from the received signal.

摘要： An improved apparatus and method for communicating information in a networked system wherein network variables are employed to accomplish such communication. Network variables allow for standardized communication of data between nodes in a network. A first node may be programmed, for example, to sense certain information and to report the information as a network variable X. A second node 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 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.
