A disclosed measuring device generates measurement data recorded by continuously measuring measurement information. Divided data items are generated by dividing the measurement data. A feature quantity representing each of the divided data items generated is acquired. A time stamp is acquired based on measurement time data, where the measurement time data include the feature quantities and measurement time identification information of each of the divided data items, the measurement time identif...

A data logger that avoids wasting power when data gathering is not needed (or is done by other means), but is activated automatically, without the need for human intervention, when it is needed. The data logger senses and stores data when a primary power source has failed. The data logger includes at least one back-up power source, and a detector switch connected to a primary power source and to one or more back-up power sources, the detector-switch detecting a condition indicative of the primar...

A logging system 2 is described in which an input signal value is compare by a signal processor 12 to a trigger-band 34 and an inner-band 36 centre about a previously logged value 34 and changing at a previously determined rate of change. When the trigger-band is exceeded at point 40, intermediate points are logged representing the maximum and minimum points since the last logged point and the point at which the inner-band was left. The intermediate points enable a more accurate subsequent recon...

An apparatus and method of determining a number of data transmissions in a sensor network are provided. More particularly, an apparatus for determining a number of data transmissions preferably includes an interest zone detector for detecting an interest zone based on a user query, a zone determination unit for determining whether the interest zone is overlapped with a sensing zone, a zone calculator for calculating an overlap amount when the interest zone is overlapped with the sensing zone, an...

A technique is proposed to provide an appropriate notification in accordance with the state of occurrence of conveyance errors. The level of maintenance required to normalize a conveying function is determined depending on the number of errors, and a notification is provided by displaying a message to a user or by transmitting a message to a service center depending on the level of maintenance. Since the message to the user indicates a specific content of maintenance to normalize the conveying f...

A method is provided for centrally monitoring machines running at remote customer sites and providing customers with adequate support. The method includes collecting machine operating data, including data for each process stage, at the customer sites, and analyzing, at a central location, the collected machine operating data for each machine. Subsequently, a solution based upon the analysis is proposed to the customer for each of the machines, and the solution is then implemented. The method als...

A pedometer measures the walk of a person and has an operating portion operated by the person to change the display mode. When operation of the operating portion is detected, a CPU proceeds to a walk determining mode, counts a walk signal from an acceleration sensor to successively store to a walk step number buffer memory, proceeds to a walk step number measuring mode when walking is determined in the walk determining mode, adds the walk step number stored to a walk step number memory, thereaft...

According to some embodiments, a light emitting diode (LED) power management and diagnostics history recording integrated circuit includes a power management circuit controlling a supply of power to the LED, a diagnostics detection circuit recording a diagnostics history for the LED, a non-volatile diagnostics history memory storing the diagnostics history; and an external interface for transferring externally the diagnostics history stored in the non-volatile diagnostics history memory. The dia...

The mean number of elevator door reversals, .mu., in groups of related door reversals, and the standard deviation, .sigma., from the mean, are used to determine the likelihood that door reversals are caused by passenger interference; the likelihood is low if a recent number of reversals exceeds .mu.+3.sigma., , is medium if two out of three recent reversals exceed .mu.+2.sigma., and otherwise is high. The floors at which related notable elevator features occur are compared to determine a floor f...
