Abstract: A cluster tree network formed by self-organization of a number of nodes. The method of self-organization includes processes for cluster formation, cluster network maintenance, intra-cluster communication. In the cluster formation process, each node discovers if any neighboring node is a cluster head or if any node is already a member of a cluster (thus making it a networked node), and if a cluster head or a networked node is discovered, each node establishes a communication link with the cluster head or the networked node. If no cluster head or networked node is discovered, the node itself becomes a cluster head. The network is maintained by each node periodically broadcasting a HELLO message to neighboring nodes, receiving responses to the HELLO message and updating a neighbor list in accordance with responses to the HELLO message. Multi-cluster networks are also provided using the processes of inter-cluster network formation, inter-cluster network maintenance, and inter-cluster communication. The resulting network has one or more clusters of nodes, each with a cluster head and a number of member nodes, each assigned a node identifier by the cluster head. In a multi-cluster network, a designated device assigns identifies to each cluster head in the network. Border nodes, which are members of at least two clusters, act as routers connecting the clusters and relaying information packets between the clusters.
Abstract translation: 通过多个节点的自组织形成的集群树网络。 自组织的方法包括集群形成，集群网络维护，集群内通信等过程。 在集群形成过程中，每个节点发现任何相邻节点是否为群集头，或者任何节点已经是群集的成员（从而使其成为网络节点），如果发现了群集头或网络节点， 节点与集群头或网络节点建立通信链路。 如果没有发现簇头或网络节点，节点本身就成为簇头。 网络由每个节点维护，周期性地向相邻节点广播HELLO消息，接收对HELLO消息的响应，并根据对HELLO消息的响应更新邻居列表。 群集间网络形成，集群间网络维护和群集间通信也提供了多集群网络。 所得到的网络具有一个或多个节点簇，每个节点具有簇头和多个成员节点，每个节点由簇头分配节点标识符。 在多集群网络中，指定的设备将标识分配给网络中的每个集群头。 作为至少两个集群的成员的边界节点充当连接集群并在集群之间中继信息包的路由器。

Abstract: A method, apparatus, and device provide for the detection of insufficient supplied power supplied to a device. A current multiplier of the device, operable as a voltage regulator, is coupled to the power source, receives a clock signal, and generates a control signal. A digital counter, clocked by the clock signal and reset by the control signal, generates an overflow output in response to an overflow condition of the digital counter that indicates that the current sourcing capability of the power source has fallen below a current threshold of the device. A compensatory response by the device in response to the detection of insufficient supplied power may be provided as well.

Abstract: A technique (300) and apparatus for sharing frequency spectrum amongst cognitive radios is provided. By maintaining an unoccupied spectral quantum between each CR device, the channel technique ensures that a device just beginning transmissions in the CR frequency band will have spectrum from which to start growing. The growth can continue up to the maximum the spectrum can support, when the bandwidth of each device has been reduced to one spectral quantum, and there are no available spectral quanta left.
Abstract translation: 提供了一种在认知无线电中共享频谱的技术（300）和装置。 通过保持每个CR设备之间的空闲光谱量子，信道技术确保刚刚开始在CR频带中传输的设备将具有从其开始生长的频谱。 当每个设备的带宽已经减少到一个光谱量子，并且没有可用的光谱量子剩下时，增长可以持续到频谱可以支持的最大值。

Abstract: A method, system, network and device provide Smart Grid Radio Frequency Interference (RFI) detection. One or more symbols or chips present in one or more received radio frequency signals are detected and the presence of one or more erred symbols or chips in the detected one or more symbols present in the received one or more radio frequency signals determined. A correlation in time between the one or more erred symbols or chips and an infrastructure waveform associated with electrical infrastructure can be determined. When the determined correlation indicates the electrical infrastructure as a source of detectable radio frequency interference to a device, a pattern flag is generated. The pattern flag or pattern flag representation can be stored and/or transmitted.

Abstract: A low power consumption protocol for low power communication devices attached to an asynchronous network is described. In this protocol, a communication device is used as a high communication duty cycle Mediation Device (MD), thus permitting other communication devices to use a low communication duty cycle framing structure. The MD functions as a storage and retrieval service for messages between two devices when one device is not able to communicate. When the previously unavailable device becomes available, it can check in with the MD to retrieve any missed messages and respond to these messages accordingly. In a communication network, each of the low power communication devices can be configured to behave as MD's for a small amount of time. Sharing this responsibility among all communication devices in the network allows each device to maintain an low average communication duty cycle. This technique is applicable to a low power, low cost, zero-configuring, self-organizing, asynchronous network.

Abstract: A peak and valley measuring circuit (40) featuring a single digital-to-analog converter (DAC) (100), a peak counter (110), a valley counter (120), and a comparator (130). The peak and valley measuring circuit (40) uses the peak counter (110) when detecting peaks of the recovered audio signal and the valley counter (120) when detecting valleys of the recovered audio signal. The DAC (100) is used in conjunction with one of the counters (110) or (120) depending on whether peaks or valleys are being detected, and is preferably a current-mode DAC.
