Abstract: A method for generating a dashboard for visualizing data streams is applicable to the fields of cloud computing and intelligent transportation. The method includes acquiring a domain model diagram of a service system and at least two data sources; determining relationship data among all domain entities in the domain model diagram based on a first representation vector of the domain model diagram; determining a data source entity relationship, a data stream relationship, and impact factors of the at least two data sources based on the relationship data and the at least two data sources; and generating a dashboard for visualizing data streams of the service system based on the data source entity relationship, the data stream relationship, and the impact factors.

Abstract: A feature synchronization method includes receiving a feature synchronization request carrying an iris feature and a first version number thereof; determining, through the first filter based on the iris feature and the first version number, a first numerical position corresponding to the feature synchronization request in the first filter, a numerical value at the first numerical position representing whether the iris feature has an updated version in the iris feature library; accessing the iris feature library through the first filter when the numerical value at the first numerical position represents that the updated version of the iris feature exists in the iris feature library, and obtaining the updated version of the iris feature through the iris feature library; and delivering the updated version of the iris feature to a request sender of the feature synchronization request for the request sender to store the updated version of the iris feature.

Abstract: A magnetic current sensor including a Wheatstone bridge circuit formed of four magnetoresistance devices; bias magnetic field application that applies a bias magnetic field to the magnetoresistance devices; and air-core coils provided on both sides of the Wheatstone bridge circuit. The Wheatstone bridge circuit generates a voltage corresponding to an induction magnetic field generated by a current to be measured flowing through the air-core coils. According to the magnetic current sensor and current measurement method, the linearity between a current and an output voltage is near 0 mA as a result of magnetic hysteresis being suppressed, and an increase in current and a reduction in size and cost are realized as a result of insulation between the current circuit side and the MR device side being excellent.

Abstract: A magnetic sensor includes: a pulse generation circuit that generates a pulse having a pulse width shorter than the power-on time of an intermittent power supply signal from an external intermittent power supply; a magneto-electric conversion element; and a switch that controls, based on the pulse, a signal application time of the intermittent power supply signal to the magneto-electric conversion element within the power-on time. The magneto-electric conversion element is, for example, an MR element that outputs two detection signals, magnitude relation between signal levels of the two detection signals changing by field intensity of an external magnetic field. The magnetic sensor may further include an amplifier that amplifies the two detection signals and a comparator that compares the two amplified detection signals.

Abstract: A magnetic sensor including a pair of permanent magnets disposed at a distance from each other so that different poles are opposed to each other, and a magnetoresistive array disposed between the pair of permanent magnets. The magnetoresistive array has four magnetoresistive elements disposed so that maximum detection directions of the adjacent elements are different from one another, and the four magnetoresistive elements are connected in a bridge circuit. The pair of permanent magnets and the magnetoresistive array are disposed so that a direction substantially orthogonal to a magnetic field detection direction and a magnetic field direction between the pair of permanent magnets are neither parallel nor perpendicular to each other.
