Abstract: An information processing device includes, at least one processor that derives frequency characteristics of time-series data of a measurement result by an acceleration sensor and determines whether the time-series data indicates a running/walking state in accordance with whether all determination conditions including at least a first condition and a second condition are satisfied, the first condition being a condition that a frequency having maximum intensity in the derived frequency characteristics is equal to or higher than a lower limit frequency set in advance, and the second condition being a condition that at least one of the frequency having the maximum intensity or a frequency having second largest intensity in the frequency characteristics falls within a range equal to or higher than the lower limit frequency and equal to or lower than an upper limit frequency set in advance.

Abstract: According to one embodiment, an anomaly detection apparatus includes a processing circuit. The processing circuit is configured to: acquire measured values from sensors installed in a system, a first function, a first threshold, and a second function to output a second threshold; generate the predicted values based on the measured value and the first function; detect that a deviation between the measured values and the predicted values exceeds the first threshold; calculate the feature quantities based on the measured values; and determine whether a number of consecutive times is equal to or larger than the second threshold to detect an anomaly or a sign of the anomaly.

Abstract: The present invention relates to a dry vacuum pump unit capable of achieving ultimate pressure of about 1 Pa. The vacuum pump unit includes a main pump (15) disposed at an outside-pressure side, and a booster pump (16) disposed at a vacuum side. The booster pump (16) and the main pump (15) are coupled in series. The booster pump (16) has a higher pumping speed than that of the main pump (15). Each of the main pump (15) and the booster pump (16) includes a pair of pump rotors (52a and 52b), a casing (50) having an inlet port and an outlet port, and a pair of magnet rotors (54 and 54) rotatable with the pair of pump rotors.

Abstract: A fire engine or a truck carrying a fire extinguishing system having a device for supplying a powder fire extinguishing agent coated with a waterproof film, e.g., a silicone resin, and a fire-fighting water delivery pipeline, is used. The powder fire extinguishing agent is added and mixed into the fire-fighting water delivery pipeline, and mixed water is delivered through a fire house and discharged from a spray nozzle provided at the distal end of the fire hose.

Abstract: The conventional fire extinguishing method requires a considerable time for knock-down and needs various fire extinguishing systems. It is made possible to shorten the knock-down time to a considerable extent and to attain a marked reduction in the amount of water used during fire fighting and significant minimization of secondary disaster damage by fire-fighting water sprayed over areas other than the fire-stricken area with a simple system configuration.

Abstract: On a credit IC card, issuing by a credit card company, brought by a credit payer with him/her is stored at least personal information for identifying a credit card company, a card number and a credit payer. Based on input of a code number by the credit payer and the stored information read out from the credit IC card, a cellular telephone is used to automatically inquire of an information center of the credit card company whether the credit can be gained. This can therefore eliminates complication involved by payment using the credit IC card and ensures smooth use of the credit IC card, with the cost performance being increased to spread the expensive credit IC card.
