Abstract: A detection apparatus and method for an ion migration spectrum include acquiring an ion migration spectrum of pure carrier gas and an ion migration spectrum of carrier gas containing a test substance sample and performing differential process on the ion migration spectrum of the pure carrier gas and the ion migration spectrum of the carrier gas containing the test substance sample to acquire a differential spectrum. The value of a characteristic peak of the differential spectrum represents properties of the sample of substances. The method avoids interferences on the migration spectrum from interference sources of the apparatus itself, thereby improving detection sensitivity and accuracy of the ion migration spectrum, and migration spectrum shift caused by variations in the environmental conditions can be found and corrected through the differential process on the migration spectrum of the pure carrier gas, thereby achieving self-stableness and self-correction of the ion migration spectrometer.

Abstract: An automatic control method of inflation is revealed. An inflator including a pressure gauge with a microprocessor automatically controls an inflated object to be inflated until the pressure reaches an initial set pressure value on the pressure gauge. After the pressure reaching the initial set pressure value, an air pump of the inflator is shut down until the pressure gets balanced. Now the value shown on the pressure gauge is lower than the initial set pressure value. The difference between an actual pressure value and the initial set pressure value is calculated and is added with the initial set pressure value to get a new set pressure value the inflated object actually needs by the microprocessor. Now the inflator starts inflation again until the pressure reaches the new set pressure value. The inflation is completely precisely.

Abstract: This invention discloses a detection method for an ion migration spectrum which comprises: acquiring an ion migration spectrum of pure carrier gas and an ion migration spectrum of carrier gas containing a test substance sample; and performing differential process on the ion migration spectrum of said pure carrier gas and the ion migration spectrum of the carrier gas containing the test substance sample to acquire a differential spectrum, wherein the value of a characteristic peak of said differential spectrum represents properties of said sample of substances, said method avoids interferences on the migration spectrum from interference sources of the apparatus itself, thereby improving detection sensitivity and accuracy of the ion migration spectrum; and migration spectrum shift caused by variations in the environmental conditions can be found and corrected through the differential process on the migration spectrum of the pure carrier gas, thereby achieving self-stableness and self-correction of the ion migra

Abstract: A part number request processing system and method is provided which allows a part number requester to efficiently obtain the verification of the part quality. The system resides in a server having a part specification database for storing a plurality of part specification label having part information and corresponding supplier information and a part test database for storing a plurality of part test records having part information and corresponding part test information. When the server receives a request, it extracts the part number specification information and test results to verify if the parts requested meet the standard, if not met, the supplier is assessed; oppositely, if met the purchase request is sent to the supplier. After delivery of the parts, test information is entered into the server via a network system to update the part specification information and part test information to provide the verification of the part purchase request.
