Method and device for termite detection and control
This is a new method in detection and control of subterranean termites. This method involves building underground stations. To build a station, dig a small area (e.g, 18″×18″) of ground about 1″ to 4″ deep; then place termite feed or bait or mix of them on the bottom; cover with a plastic sheet; and finally cover it with soil, mulch, or turf. Cardboard can be used as feed among other choices. This method is very effective because the plastic sheet can keep moisture from escaping and preserve the feed/bait. Also when termites are foraging to find food, they will be stopped by the plastic sheet and be gathered there. The layer above the plastic sheet provides good insulation to disturbance. Larger size of the station than a traditional baiting container also helps termites to find the station more quickly and more reliably. |

Buffer relay management within single user, multiple user, multiple access, and/or MIMO wireless communications
A relay wireless communication device is implemented to perform buffer management and coordination with a source wireless communication device. A relay wireless communication device (generally, a relay) informs a source wireless communication device (source) of the status of memory therein to store messages intended for a destination wireless communication device (destination). For example, the source transmits information to the relay, which buffers information before forwarding it on to the destination. This buffering may be a function of the source having additional information intended for the relay and/or destination. The relay performs appropriate signaling, such as suspend transmission requests and resume transmission requests, to inform other devices in the system of its memory storage status (e.g., such as when having an actual or anticipated overflow). In one implementation, a suspend transmission request may be implemented by setting a particular bit within a communication from the relay to the source. |

Dynamic latency-based rerouting
A switch creates and dynamically updates a latency map of a network to adjust routing of flows. Further, the network is monitored to detect latency issues and trigger a dynamic adjustment of routing based on the latency map. In this manner, a flow can be routed along a route (i.e., a faster route) that provides less latency than other available routes. The latency map can be generated based on latency probe packets that are issued from and returned to the source switch. By evaluating many such latent probe packets that have traveled along many available routes (e.g., corresponding to various ports of the switch), the switch or associated administrative logic can dynamically adjust the latency map to updated latency information of available routes. Therefore, responsive to a trigger, the source switch can dynamically adjust the routing of a flow based on latency issues discerned from the network. |

Non-linear time domain channel estimation in OFDM systems
An OFDM receiver generates an initial channel impulse response in response to a received OFDM signal. The receiver determines the time span within the initial channel impulse response in which significant paths are present. An intermediate channel impulse response estimator identifies paths within the initial channel impulse response and generates an improved intermediate channel impulse response. A channel impulse response estimator performs a second non-linear process to generate a channel impulse response. An equalizer responds to the channel impulse response and the OFDM symbol to equalize the OFDM symbol. Metrics are generated that can be used for effectively stopping the second iterative non-linear process. |

A CDSL, effective CDSL, or CSL may be arranged in an imaging system for one or more of optical imaging, microscopy, micro-spectroscopy and/or THz imaging. |
