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.

An interactive system and method for navigating a person from a starting point to a destination, using a wireless location determining device and a wireless navigating device. The person sends a request for navigational directions via the wireless location determining device. Using a database that contains the geographic location and a corresponding name of the starting point and the destination, the request is answered and navigational information is sent to the wireless navigating device. The database was previously established by recording the movement of subjects, using a wireless location determining device, as the subjects moved from place to place in their environment. When the number of occurrences of subjects passing by any individual location reached a predetermined threshold, the subjects were prompted to enter a name that described and corresponded to that location. Using the provided navigational information, the person moves from the starting point toward the destination. Optionally, the wireless location determining device periodically sends the current geographic location of the person as he travels. Optionally the wireless location determining device periodically receives additional navigational information in response to the periodically sent information to update the person.

An interface block (300) carries a removable electrical connection (310, 312) that can be quickly connected and removed from a high speed machine for picking and placing electronic components. The interface block is attached to a vacuum ported tool changer (200) which further couples to a heated end effector (100) to create a removable heated nozzle assembly (50). The entire assembly can be easily plugged into and removed from a high speed placement machine.

Each user can contribute to an original search and to refining the results of the search. Preferences of all of the users are considered in the search even while those preferences can be kept private. In some embodiments of the present invention, at least two users each submit a search query. The multiple search queries are logically combined to produce one set of search results. The results can be reviewed by the users and refined if necessary. In some embodiments, a search query can be specified by a single user, but the search engine takes into consideration the stored preferences of multiple users (in addition to the search query itself, of course).

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.

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.

A precision placement apparatus comprises an improved probe for aligning a component and a substrate based upon features on the inner surfaces arranged in facing, spaced relationship, prior to assembling the component to the substrate. The probe comprises a dual prism assembly having a first face for viewing the componenet surface and a second face for viewing the substrate surface. The dual prism assembly superposes the images of the surfaces to permit an operator to accurately align the elements. A liquid crystal shutter is mounted onto one face of the dual prism assembly to exclude the image of the corresponding surface and thereby allow the operator to quickly determine the features of the other surface in order to make the appropriate adjustments.

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.

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:
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.
