摘要:
An object (201) (such as a containment mechanism) supports both a functional electrical circuit (203) and an electrical circuit (202) to which the functional electrical circuit is responsive. In a preferred approach the functional electrical circuit has both a low power state of operation and a higher power state of operation. Upon detecting (104) that an area of connectivity of the electrical circuit has been severed (via, for example, corresponding manipulation of the object itself), the functional electrical circuit responsively operates (106) using the higher power state of operation.
摘要:
One facilitates determination of a path that comprises a plurality of specific locations (201). In an optional though preferred embodiment these specific locations comprise locations where a given functional ink will preferably be printed using a continuous printing spray. Also in an optional though preferred embodiment this path will also avoid at least one predetermined area (701) where such a functional ink should not be printed. In a preferred approach this process (100) generally provides for identifying (101) these specific locations and further identifying (102), when applicable, the one or more predetermined areas to be avoided. This process then preferably uses a processor to effect at least one (and preferably both) of using (103) a genetic algorithm to identify a preferred path that includes the plurality of specific locations and using (104) an A* algorithm to process a candidate path to provide a selected path that includes the plurality of specific locations while also avoiding the at least one predetermined area.

A method for resource management in a supply chain is provided. The method is used by a pallet device (106) that can be associated with a pallet (104) in the supply chain. The pallet is associated with one or more resources. Further, the supply chain includes a decentralized control system (100) that has at least one system server, a plurality of pallets, a plurality of pallet devices, and a plurality of resources. The method includes detecting (302) an event and acquiring (304) status information of at least one of the plurality of pallets in response to the event. Further, the method includes determining (306) a reporting condition of at least one of the plurality of resources, based on the status information. The method includes reporting (308) the status information to one of at least one system server and at least one of the plurality of pallet devices, based on a positive reporting condition.
摘要:
A machine-implemented method for simulating a supply chain for a product may include receiving real-time information regarding delays from at least one link in a product supply chain, simulating events in a supply chain based on the received information, and determining, based on the simulation, whether the costs and/or level of service relative to the product is unacceptable.

A method and apparatus for determining a range within a wireless communication system is provided herein. The range information can then be used to locate a node (e.g., an asset tag). During operation, the minimum transmission power of a source transceiver (e.g., an RFID reader) that enables a tag to be detected will be used to indicate distance. Changes in transmit power will be used to indicate relative changes in distance to a particular node. The reader will be configured to always operate at a transmission power that will result in a certain percentage (e.g., 50%) detection rate for a target transceiver (e.g., an RFID asset tag). As the reader moves closer to the tag, the minimum detection power will decrease; as it moves farther from the tag, the minimum detection power will increase. This information is displayed to give a general change in range information between the RFID reader and the asset tag (e.g., increasing range or decreasing range). An individual will be able to easily locate the asset tag by using the displayed information.

Disclosed is a system for updating an RSSI-based map. A scanning devices notes which tags are seen during a scan and measures a “proxy distance” from the scanning device to each tag. When the scan is initiated, the scanning device measures the RSSIs from the local WAPs. The current location of the scanning device is determined by triangulating from the proxy distances of the scanned tags. That location is then correlated with the contemporaneously measured RSSIs. The correlation is used to update the RSSI-based map. In some embodiments, it is not the scanning device that measures the RSSIs. Instead, the WAPs measure the RSSIs from the scanning device whenever the scanning device transmits the results of a scan. In some embodiments, the operator of the mapped environment places scannable tags at fixed locations. Scans of these fixed-location tags are especially useful when determining the current location of the scanning device.
摘要:
A virtual environment server. The server manages time-shifted presentation data between multiple participants in a shared virtual environment system. The server includes a routing module configurable for coupling to multiple participants, a real-time data management module coupled to the routing module, a time-shifted data management module coupled to the routing module, and a data store module coupled to the real-time data management module and to the time-shifted data management module. Participant output presentation data is received from the participants, stored as real-time presentation data, and transferred to appropriate participants. In response to requests from a requesting participant to obtain time-shifted presentation data from a time-shifted participant and any influence participants, time-shifted presentation data is retrieved from the data store module and transferred to the requesting participant. Influence participants are participants whose input presentation data are influenced by time-shifted participant and whose output presentation data influence presentation environment of requesting participant.

摘要:
Disclosed is a method for a scanning device to tell its user how to best orient the scanning device to scan a target location. The user approaches the target location and initiates a scan. The results of the scan are analyzed and compared to information about the target location. Based on the analysis, the user is told how to re-orient the scanning device, if that is necessary to achieve an acceptable re-scan of the target location. In a preferred embodiment, a screen on the scanning device presents a two-dimensional map based on the scan results and on the known relative locations of the target location and of nearby non-target locations. Locations on the map are highlighted to tell the user the results of the scan and to direct him to re-orient the scanning device if necessary.
