Abstract:
PROBLEM TO BE SOLVED: To communicate metadata with a bandwidth narrowed and power saved. SOLUTION: A sensor comprises measurement data to be transmitted to a data collector, metadata that is to be transmitted to the collector and constituted so as to support the data collector when any of the transmitted measurement data, and a control section for transmitting at least a part of the metadata whenever transmitting opportunity occurs. The control section transmits a part of the metadata instead of a part of the measurement data, and determines when the part of the measurement data is repeated. COPYRIGHT: (C)2007,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To recognize a present setting at any instant without requiring frequent reports from a setting server or significantly increasing communication requirement. SOLUTION: A probe used in a measurement system comprises a memory for storing data suitable for possible settings about the probe and a processor for setting one of the possible probe settings. A positioning device is provided, the possible probe settings are used by the processor, and preferably a position parameter for selecting a setting from the possible settings is provided at least partially based on a defined position of the probe presented by a controller of the measurement system.

Abstract:
PROBLEM TO BE SOLVED: To provide a parameter measurement system capable of performing direct access to the performance of the system from the customer's viewpoint. SOLUTION: The parameter measurement system which measures parameters accessible from mobile equipment communicating over a communication network, the communication network including first and second technology coverage areas provided by each of first and second service providers, includes an agent characterized in comprising: a measurement means for measuring a determined parameter of operation of one of the mobile equipment and the first and second service providers and detecting changes in the service providers, a means for changing measured parameters to make parameter measurements corresponding to the detected changes in the service providers; and a transmitter which transmits the measured parameters to the first service provider over the communication network.

Abstract:
PROBLEM TO BE SOLVED: To effectively use transmission bandwidth in a wireless probe measuring system. SOLUTION: A system and a method are disclosed for managing bandwidth in the wireless probe measuring system. The system and the method may include: a means for receiving an indicator at the wireless probe to begin taking measurements of one or more variables; a means for measuring the one or more variables; a means for calculating a set of statistical values at the wireless probe using the measured one or more variables; and a means for transmitting the set of statistical values to a central station.

Abstract:
PROBLEM TO BE SOLVED: To reduce burden of a server and a database that must manage an individual set state of each probe in managing and distributing set information of each probe. SOLUTION: This method used in a measuring system comprises a step of receiving set data of a plurality of separated probes. The set data of each probe is not uniquely related with the probe, and can establish the setting of the probe. This method also comprises a step of communicating a measured value according to the set data. COPYRIGHT: (C)2007,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To quickly identify a special data packet by checking the special data packet not including an error detection code, obtaining additional data to be included in the packet and correcting the special data packet including the data. SOLUTION: A network consists of two node groups that are a group comprising nodes 1-4 and a group comprising nodes 5-10. Each group has a central hub with an individual link L set to each node. That is, a hub 1 is connected to the nodes 1-4, a hub 2 is connected to the nodes 5-10, and a link L' interconnects the hubs. Each of the hubs simply acts like a router. That is, when a hub receives an input signal from either of the links L and L', the hub transmits copies of the signal to all other nodes connected to the hub. For example, when a node 8 transmits a signal, it reaches the hub 2 and the hub 2 transmits the copies of the signal to the other 5 nodes directly connected to the hub 2.
Abstract:
Measurement sensors are designed to provide metadata to data recording devices in an opportunistic manner to conserve bandwidth and/or power. In one embodiment, the metadata is communicated to the recording device during opportunistic periods, such as, for example, when actual data transmission can be skipped, or when battery level is high, or when there is enough bandwidth, i.e., other sensors are not using the full allocated bandwidth. In one embodiment, a plurality of sensors each only send a portion of their data such that all the portions taken together form the complete metadata. In another embodiment, each sensor only sends an identification of its type and the receiving device 'looks up" the full metadata from a database.
Abstract:
A system operative to collect and analyze data in a digital network includes a probe layer comprising a probe disposed in the digital work. The probe is configured to identify and capture data from frames passing through the probe. The system also includes an analysis layer operative to receive the captured data from the probe. In addition, the system includes an application layer comprising a system master operative to mediate between an application and the probe.
Abstract:
A wireless coverage mapping technique is arranged to display the signalling location for each measured signal as well as the measured signal strength. In one embodiment, the resulting map contains a coloured circle at the point where be signal measurement is taken and a line connecting the circle to the signalling location in communication with the location of the measurement at the time the measurement is taken. If desired, the colour of the line can reflect the connectively metric while the style of the line can convey other information about the measurement or the measurement type. Also, if desired, the direction of movement of a mobile detector (for example, a cellular phone) can be displayed. The map can be used, for example, to determine neighbour lists such that by observation the administrator can match the neighbour list for a particular connection against the transmitter actually selected for that transmission. In this manner, neighbour lists can be updated to reflect the actual usage patterns as shown by the mapping technique disclosed herein.
