Abstract: The present invention relates to a current sensing device comprising: a bus bar including a plurality of low-resistance metal portions separated from each other with a resistance portion therebetween; a printed circuit board arranged below the bus bar; a plurality of fixing pins which are joined to the metal portions of the bus bar to fix the bus bar on the printed circuit board and provide a current path between the metal portions and the printed circuit board; and at least one Hall sensor module. At least a portion of the Hall sensor module is inserted into a sensor hole formed in at least one of the low-resistance metal portions of the bus bar.

Abstract: A method for changing a route when an error occurs in an autonomous driving AI includes collecting error information of the AI when an error of the AI has occurred, extracting, from a storage, past error information about a same kind of AI as that of the AI based on the error information of the AI, generating an error analysis result based on the past error information, generating an error analysis result message based on the error analysis result, and determining whether the driving of the autonomous driving vehicle needs to be stopped based on the error analysis result message.

Abstract: Disclosed herein is an untact DC electric-field sensor having improved sensitivity. The untact DC electric-field sensor has a circuit composed of a variable capacitor and an RF generator and improves sensitivity through resonance of the circuit by connecting an inductor to the sensor.

Abstract: Disclosed herein is an optical device for augmented reality capable of providing an expanded eyebox through polarization. The optical device for augmented reality includes: an image output unit configured to output a first virtual image light polarized in a first direction and a second virtual image light polarized in a second direction; an optical means configured to transmit real object image light therethrough to the pupil of an eye of a user; a first optical element disposed in the optical means, and configured to provide a first virtual image by transferring only the first one of the first and second virtual image lights to the pupil of the user; and a second optical element disposed in the optical means, and configured to provide a second virtual image by transferring only the second one of the first and second virtual image lights to the pupil of the user.

Abstract: According to an embodiment of the present disclosure, there is provided a preventive diagnostic system for a GIS that includes a plurality of data acquisition systems (DAS's), a central communication unit (CCU), and a local server. The DAS generates an ICD file representing a content of the configuration of the DAS using a logical node designed for the preventive diagnostic system for a GIS and delivers the ICD file to the CCU, and the CCU performs a network connection so as to communicate with the DAS in compliance with IEC 61850 based on a content of the ICD file delivered from the DAS. According to the embodiment of the present disclosure, by applying IEC 61850 to the preventive diagnostic system for a GIS, smooth integration with a substation automation system and an efficient operation can be achieved.
