  • Patent number: 6604225
    Abstract: In calculating an electromagnetic field intensity by a moment method, real and imaginary parts of a mutual impedance, mutual admittance, and mutual reaction between elements and of the elements themselves are approximated by a sum of terms each with a frequency raised to a power. The mutual impedances, etc. at a plurality of sample frequencies are calculated using known mathematical equations, and simultaneous equations obtained by substituting the sample frequencies and the mutual impedances at the respective sample frequencies into an approximate equation are solved to calculate approximation coefficients for the approximate equation. Using the thus obtained approximate equations, the mutual impedance, etc.

  • Patent number: 6446052
    Abstract: A system and method for obtaining traceable anonymous digital cash from a bank using a trustee as a trusted third-party. A user establishes her identity with the trustee using a secret known by the user. The user transmits to the trustee information describing a blinded traceable digital coin. The user receives from the trustee a trustee token including a signature by the trustee on the blinded coin. The user transmits the blinded coin and the trustee token to a bank. The user receives a signature from the bank certifying the blinded coin. The user can then unblind the coin, and spend the coin at a merchant. The system and method support both tracing of the identity of a user from a coin, referred to as coin tracing, and generation of a list of all coins belonging to a given user, referred to as owner tracing. Both of these operations require very little computation and database access. To determine the identity of the user, the trustee can generate the list of coins associated with a user.

  • Patent number: 6366894
    Abstract: A value transfer system using integrated circuit cards for exchanging electronic cash in off-line transactions employs cryptographically secure message protocols. Cards are loaded each with two schemes from a series and interaction between cards determines and uses the oldest scheme shared by the cards, causing one card to switch schemes irrevocably if that common scheme is its second scheme. In this way, a switch to a new scheme can migrate through the system.

  • Patent number: 6192324
    Abstract: This invention is an on-board means to verify that a vehicle's exhaust emissions control system functions normally. It monitors hydrocarbon (HC) exhaust emissions for a few minutes after a cold start or at other selected times. If used from cold start, it is an on-board approximation to taking the first bag sample in an FTP test. The measurement involves storing a portion of the exhaust HC. Various embodiments are discussed. Some involve measuring the cumulative amount of stored HC (as on a substrate) during the test. Other embodiments wait until the end of the test to measure the amount of stored HC. At the end of each test (or trip), the storage means is returned to an empty state to await the next test. If HC is stored on or in a substrate, for example, the temperature of the substrate is raised. This decreases the amount of stored HC vapor and renews the substrate for the next test.

  • Patent number: 6148266
    Abstract: A method of properly correcting a base line. A concept of flexibility of a base line is introduced as an input index and a gravitation is presumed between the base line and signal data which is measured, thereby constructing a method of correcting the base line which changes gentler than a change in signal with respect to time in a peak area and which is sensitive to an area where a value of the signal data is small. A base line like a natural and smooth curve which isn't easily influenced by a local change in signal such as noise or the like can be set by an input of the flexibility.

  • Patent number: 6082888
    Abstract: A pump unit is provided which sucks a material having a high viscosity contained in a container and to pump it to a nozzle under pressure. An axial member which performs sucking and pumping of the material is connected with the pump unit. The axial member is axially slidable by the pressure of air supplied to the cylinder. The material which is sucked into the pump unit is discharged from the nozzle by the increase in pressure occurred when the axial member descends. A sensor is provided in the vicinity of the axial member. A result of detection of the sensor is supplied to a controller. A reference speed when constant rate application is performed is presettable in the controller. Correction of pressure is conducted by comparing the actual moving speed of the axial member with the reference speed.

  • Patent number: 6081766
    Abstract: Explicit representation of molecular shape of molecules is combined with neural network learning methods to provide models with high predictive ability that generalize to different chemical classes where structurally diverse molecules exhibiting similar surface characteristics are treated as similar. A new machine-learning methodology is disclosed that can accept multiple representations of objects and construct models that predict characteristics of those objects. An extension of this methodology can be applied in cases where the representations of the objects are determined by a set of adjustable parameters. An iterative process applies intermediate models to generate new representations of the objects by adjusting said parameters and repeatedly. retrains the models to obtain better predictive models. This method can be applied to molecules because each molecule can have many orientations and conformations (representations) that are determined by a set of translation, rotation and torsion angle parameters.

  • Patent number: 6076073
    Abstract: The invention provides a method for protectedly debiting an electronic payment mechanism, such as a telephone card. In the communication protocol between the payment mechanism and a payment station, an authentication is used to identify the payment mechanism during various steps of the protocol. According to the invention, the authentications are mutually related by states of a cryptographic process in order to be capable of detecting an interference in the protocol. The method may be applied to existing payment cards having a dynamic memory, it being guaranteed that the contents of the dynamic memory, in which there is located information related to the authentication, is not lost during the protocol.
