Filed: 1999-09-03
Abstract: PROBLEM TO BE SOLVED: To prevent a classification from frequency changing in a seating occupant detecting device and a seating occupant detecting method for performing the classification according to a physique of a seating occupant.

After the detected weight W becomes less than the second threshold TH2 to determine a light class, the determination of the light class is kept until the detected weight W becomes not less than the first threshold TH1. Instead of the detected weight W at each time point, an average value of the detected weights W over a predetermined period may be used. The classification may be performed based on a ratio of a period when the detected weights W are not less than the first threshold TH1 in the predetermined period.

IPC: G01N27/06
Filed: 1988-10-07
Abstract: PURPOSE:To enable continuous measurement of on density necessary for a high- temperature water quality control by measuring a conductivity for an aqueous solution to be measured at a different temperature and time at more than one points. CONSTITUTION:First, at time ti, a room temperature conductivity room (ti) and a high-temperature conductivity Khigh (ti) are established. When the time ti is for measuring an ion density, an identification of the type of ion and a determination of a density thereof are performed. A rate of dependence alpham(ti) of the types of ions is determined on the room temperature conductivity Kroom and then, the subsequent step is taken. Otherwise, this ion density process is skipped and the subsequent step is taken. Then, a hourly change in a ratio Khigh(ti-a)/Kroom (ti) between the high-temperature conductivity and the room temperature conductivity is examined, wherein (a) represents a delay in time between the start of water to be measured from a high-temperature conductivity meter and the arrival thereof at a room temperature conductivity meter. When a change in Knigh (ti-a)/Kroom (ti) is below a reference value, no change in ion composition can be considered. Thus, an ion density Cm(ti) is determined at the time ti by a relational expression.
