A pattern matching unit performs pattern matching on present data obtained this time in clinical examination of a part of a subject and previous data obtained last time in the clinical examination of the part with reference patterns. Reference patterns that are most closely approximate to the present data and the previous data are selected. A distance calculator calculates a distance between selected reference patterns. A determining unit determines whether a re-examination is necessary based on the distance.

A cartridge is set in a printer main unit, and has a remaining toner measurer which measures toner in a toner chamber upon setting of the cartridge. A cartridge memory stores information of a remaining toner amount measured previously. CPU compares the remaining toner amount measured newly with the remaining toner amount measured previously and read from the cartridge memory. If there is an increase in the toner, the cartridge is determined as improper cartridge reloaded with the toner. An alarm signal is generated. Also, printing is inhibited. In another preferred embodiment, shortage information is assigned to the cartridge upon using up the toner. The cartridge, if it has the shortage information, is determined as improper. If a characteristic of the toner is not within a reference range, the cartridge is determined improper. In another preferred embodiment, an upper limit of the number of times of toner reloading is predetermined. The cartridge is determined improper if the reloading time number comes up to the upper limit. The improper cartridge is set in a state in which operation is inhibited. Also, when the cartridge is disassembled, the improper cartridge is inhibited from operating.

In a method and system for authenticating locally-stored program code, a first checksum is computed using the locally-stored program code, the computed checksum is compared with a second checksum known to be valid and, if the two checksums are determined to match, the locally-stored program code is deemed valid and authentic. For increased certification reliability and dependability, before computation of the first checksum a predetermined challenge is added to the stored program code, so that the first checksum is computed from the combination of the stored program code and the challenge. This enhancement enables secure use of stored program code in applications that demand high security. Users of such software may therefore rely on the authenticity of the data processed by the software and of the data and results reported on the display of a mobile phone or keyboard throughout the entire process or transaction.

An encryption error monitoring system for checking packets transmitted between a private network and an external network. The system includes includes a detector module (60) which is connected to receive the packet for determining whether or not the packet is successfully encrypted in accordance with a specific security protocol such as IPSec (Internet Protocol Security). The detector module reads from the packet a sender's address and a destination address, and provides an error signal when the packet is judged not to be successfully encrypted. A manager module (80) is connected to the detector module within the private network to create, upon receipt of the error signal, a report including the sender's address and the destination address with regard to the packet judged not to be successfully encrypted. The detector module is configured to have a judge means (66) which reads a header of the packet and checks whether or not the header includes a protocol code that matches with a particular code identifying the specific security protocol. When the header does not include the protocol code in match with the particular code, the judge means provides the error signal to notify the encryption error. Thus, the encryption error can be determined only by referring to the unencrypted header and therefore without necessitating the decryption of the packet.

The test signal is supplied at a place in the sensor from which it reaches the output terminal in unchanged form or in processed form—after the performance of the at least one linear signal processing step—only in the case of a functional sensor. An output signal present at the output terminal is compared with the test signal and a diagnosis signal is generated, which indicates whether the test signal is present at the output terminal. The test signal is filtered out of the output signal and the remaining signal is applied as the measurement signal at a measurement signal output of the sensor module.
