Abstract: A current sensor includes a plurality of unit groups mounted in a first case and a current sensor includes a first case that is made of a resin and includes a first opposing part, a second case that is made of a resin and includes a second opposing part, a substrate mounted in at least one of the first case and second case, and a plurality of unit groups mounted in the first case and second case, each unit group measuring an induced magnetic field. second case, each unit group measuring an induced magnetic field. Each of the plurality of unit groups includes one or more measurement units arranged in a second direction. A current path and a first magnetic shield, each of which is formed integrally with a first opposing part, are positioned so as to be separated by a first distance. In all unit groups, all first distances are substantially the same.

Abstract: There is provided a current sensor capable of performing malfunction determination with high accuracy even under the influence of an adscititious magnetic field. A current sensor includes first and second current sensor units, a computation unit, a storage unit, and a determination processing unit. The first current sensor unit measures a target current. The first and second current sensor units have almost the same sensitivity. The computation unit calculates and outputs an addition value and a difference value of outputs of the first and second current sensor units. In the storage unit, the addition and difference values output from the computation unit are stored. The determination processing unit determines whether a malfunction has occurred by using the addition and difference values stored in the storage unit. The determination processing unit determines that a malfunction has occurred, in a case where there is a correlation between the addition and difference values.

Abstract: An intellectual-property accounting management device includes an acquisition price storage unit (202) for storing an acquisition price for each intellectual property, and means for updating the acquisition price in the acquisition price storage unit (202) by inputting the amount of the acquisition expense expended for acquiring a particular intellectual property to perform intellectual property accounting processing.

Abstract: An intellectual property right selling/buying system and method enables transfer of an intellectual property right selling/buying right to a broker by employing the call option method and acquiring a call option fee. An application for selling a right to be sold is received from an applicant terminal and a value evaluation price of the right is determined by referencing a right evaluation database. According to a selling period applied and the value evaluation price, a call option fee is calculated, and the sale price of the right is determined based on the value evaluation price and the call option fee. In the event that a trading is successful, a purchase price is transferred from the buyer to the broker and refunds determined based on the value evaluation price and the call option fee is transferred from the broker to the applicant.

Abstract: A certificate transceiver includes a CCD sensor unit for reading certificate data from a certificate, a printing unit for writing data into a certificate form, and a network interface for transmitting and receiving data via the communication line. A certificate transmitter side reads and transmits certificate data of the original certificate and writes invalidating data into the certificate by the printing unit. A certificate receiver side writes the received certificate data into a certificate form by the printing unit.

Abstract: An obstacle preventing device includes an obstacle detecting sensor, a steering wheel, a vibrator secured to the steering wheel, a controller for controlling driving of the vibrator, and a vehicle velocity detecting sensor. When the distance between a vehicle body and an obstacle becomes equal to a predetermined threshold distance, the controller outputs a drive signal to the vibrator in order to vibrate the steering wheel by the vibrator.
