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： Systems, methods, and apparatuses are disclosed for choosing the modulation mode using packets transmitted by a sender to a receiver, wherein the packets contain data patterns unknown to the receiver. In some embodiments, the sender sends of a data packet in the most robust mode available, such that the packet can be correctly received by the receiver under even the noisiest conditions. The data contained in the packet is demodulated and decoded. A cyclic redundancy check is performed to ensure that the resultant data is error-free. Once the transmitted payload data is known, the original error coding can be re-applied to the payload data to produce the transmitted bit stream. Comparison of the demodulated bit stream to the regenerated transmitted bit stream yields the pattern of errors. The pattern of errors is analyzed and a higher throughput decoding scheme is chosen based on the results of the analysis.

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： 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 system manages the quantity of responses by discoverable lighting devices in a network, in responding to a device discovery request from a lighting control server. Each device includes a random target number accessible via the network, comprising a plurality of sequentially arranged fields, each field including a random target integer selected from a range of integers, based on a position of the field in the sequentially arranged fields of the random target number. The device discovery message includes a request to respond to the message if a specified value in the message compares with a target integer in a specified field of the random target number included in the receiving discoverable device, the specified value and specified field in the request based on an estimated percentage of the devices in the network expected to respond. Each device generates a response to the received request, if there is a successful comparison.

摘要： A distributed system for traffic monitoring and event detection includes a plurality of video units within viewing distance of a thoroughfare to be monitored. Each video unit processes a video stream while monitoring events at the thoroughfare, identifies and analyzes events, encodes traffic meta data characterizing the analysis, and transmits the meta data to a central controller. The central controller stores a geographic map representing the thoroughfare, correlates the meta data received from the video units, and forms a composite representation of the geographic map and the correlated meta data. The central controller replays previously stored composite representations of the geographic map and the correlated meta data, which were monitored under mutually different event conditions. The central controller is also configured to allow changes to previously stored composite representations of the geographic map and to the correlated meta data for the purpose of understanding the impact of change.
