Even when setting a complicated spam judging condition, it is possible to reliably determine a necessary electronic mail in reality (i.e a mail that is not a spam mail), without deleting a necessary electronic mail or the like. Based on the assumption that an electronic mail from a mail address to which transmission was performed in the past has a high possibility of not being a spam mail, a transmission destination mail address of an electronic mail transmitted to outside the organization is recorded as a permitted mail address (Step 506-Step 510), and when a transmission source address of an electronic mail destined to inside the organization matches a mail address registered in a permitted mail address database (Step 511: Yes), processing is performed to unconditionally receive this electronic mail (Step 504).

The present invention provides an abnormity determining method for a battery pack and the battery pack thereof. Whether the secondary battery is abnormal can be reliably determined in the battery which is obtained through connecting a plurality of secondary batteries. In charging of the secondary batteries, after stopping EFT which is inserted into a charging/discharging path for charging/discharging for 250ms (between time T1 and time T2 and between time T3 and time T4) is repeated every 10 minutes, the secondary battery is conducted. Based on differences (deltaV(1) and deltaV(2)) of the secondary batteries before conduction and after conduction and charging current detected before conduction, the internal resistance of the secondary battery is calculated every 10 minutes and is stored in a RAM. Hereon, on condition that the difference between a newly calculated internal resistance and the internal resistance which is formerly calculated and stored in the RAM is larger than a first threshold value, whether the secondary battery is abnormal is determined through comparing a difference between the newly calculated FCC (full capacitance) and the FCC that is formerly calculated and stored in the RAM with a second threshold.

An obstacle detection apparatus in a host vehicle derives the value of absolute speed of a target object such as a preceding vehicle, and the distance of the object from the host vehicle, and compares the absolute speed with a threshold value that is increased in accordance with increase in value of a parameter which adversely affects the accuracy of deriving the absolute speed of the target object, such as the distance of the target object from the host vehicle or the running speed of the host vehicle. A judgement as to whether the target object is stationary or in motion is made based on results of the comparison.

The invention relates to a passive passage correcting method of a small-size array.
