A method of distributed control of a wireless mesh network without knowledge of global topology. The method includes: a station joining the network with any current member by propagating the join-request, or two meshes merging using the steps of: one mesh joining the other as a whole and then re-synchronizing its timing. The method further includes: first, each station periodically transmits a beacon; second, in response to a beacon being no longer detected, a station transmitting a bitmap of stations that it can still receive; third, each station responds by adding stations that it can receive with all of the bitmaps received from other members, and retransmitting the updated bitmap; fourth, after time for all stations to respond, all stations base current membership on the bitmap. The method further includes: determining sharable time slots that will not interfere with neighbors or other slot sharers, using and then releasing those slots.

To identify a fault location easily if there is any fault detected in a network. If an optical path is switched from a working system to an auxiliary system due to a fault, an optical test signal originated from a network node apparatus located at an end point of the optical path is looped back by another network node apparatus on the optical path for the working system. This looped back optical signal is received by the network node apparatus of an originator, in which the signal quality of the optical test signal is measured by a determination device, thereby detecting the presence or absence of the fault on the path through which the optical test signal has been passed. A test receiver within the determination device measures a BER, an S/N ratio, an optical power, or an optical wavelength, whereby it is possible to detect not only the fault location due to disconnection of a link but also degradation in the signal quality.

This paper describes an EDA (Electronic Data Automation) method and computer software invention for connectivity verification of IC mask Layout database versus IC Schematic; LVS Check (LVS: IC Layout versus IC Schematic) over the internet. The technique takes advantage of a unique algorithm to check the mask layout database connectivity, compare it with its corresponding schematic diagram for any mismatches in the mask layout polygons connections. The input of the tool is a mask layout database blocks (i.e.: IC layout) that were made manually and/or automatically using synthesized tools. These blocks may have some connectivity mismatches that need to be fixed in order to match the corresponding integrated circuit (IC) schematic diagrams. The output of the software tool is a text based descriptive log file and errors markers pointers that may be read into the mask layout database in order to point any connectivity mismatches of the mask layout database, comparing it to its corresponding schematic diagram. The end result is a mask layout set of markers and a text format log file that describes any mismatched connections in the mask layout database, comparing it to its corresponded schematic diagram. The software performs on individual mask layout blocks and/or on hierarchical structure of mask layout blocks. The system works hierarchically and/or flat. System also checks mask layout database incrementally, means only blocks that have been changed are checked. The system can be run via the internet using our secured protocol. The system offer a web based control panel to execute all necessary setups for submitting LVS check over the internet.

An intermittent computing system state and intermittent computing module is described for a power-constrained personal computer. In the intermittent computing system state, the power-constrained personal computer may transition between sub-states of the intermittent computing system state according to an intermittent computing schedule. Each intermittent computing sub-state may be associated with hardware power sets and software power sets.

In the intermittent computing system state, periods of high functionality may be available over extended periods without the high power consumption associated with a continuous working system state. Average power consumption may be adjusted by varying the intermittent computing schedule.
