A group of network packets is broadcast and forwarded by a most distant receiving node that received all packets of the group. A receiving node's clock is automatically adjusted, based on which packet(s) of a group of packets was received. A sending node synchronizes near-by receiving nodes. Nodes are provisioned over-the-air, with built-in scheduling. Health and welfare information piggybacks on other network traffic. |

MAC design for wireless hot-spot networks
In widely deployed wireless “hot-spot” networks, nodes frequently join or leave, inelastic/elastic and saturated/non-satuarted flows coexist. In such dynamic and diverse environments, it is challenging to maximize the channel utilization while providing satisfactory user experiences. In this invention, one proposes a novel contention-on-demand (CoD) MAC scheme to address this problem. The CoD scheme consists of a fixed-CW algorithm, a dynamic-CW algorithm, and an admission control unit. The fixed-CW algorithm allows elastic flows to access limited system bandwidth; the dynamic-CW algorithm enables inelastic flows to contend for channel on demand and quickly adapt to network change; and the admission control unit rejects overloaded traffic for providing good user experiences. One then performs an asymptotic analysis to develop a simple but efficient admission control rule. Finally, extensive simulations verify that the scheme is very effective and the theoretical result is very accurate. |

Method and apparatus for on-chip per-pixel pseudo-random time coded exposure
Conventional methods for imaging transient targets are constrained by a trade-off between resolution and frame rate, and transient targets moving faster than the detector frame typically result in image blurring.

However, these DFPA systems are not capable of multi-target and multi-frequency discrimination. Imagers described herein achieve multi-target transient signature discrimination orders of magnitude faster than the readout frame rate using in-pixel electronic shuttering with a known time-encoded modulation. Three-dimensional (x,y,t) data cube reconstruction is performed using compressive sensing algorithms. |

Networks of cameras and/or other sensors enable a sensor monitoring system or other computer system to control hiding devices used to enable the cameras and/or other sensors to evade danger by hiding or being disguised. Detection and/or determination of potential danger is garnered from data, from some of the cameras and/or sensors, that they or other of the cameras and/or sensors may be facing eminent danger of discovery, manipulation, alteration, deactivation, and/or damage. The hiding devices are caused to hide or disguise the sensors and/or cameras that appear to be in danger. Hiding or disguising can continue for at least a finite duration of time, or until indication of danger is gone. Some of the cameras and/or other sensors, and their associated hiding devices, can be turned off or made to sleep for periods of time until at least awaken by time-out events or by events indicating a need to do so. |
