Provide support for evidence record management of legal compliance in an organization. A legal compliance support system manages legal operation management information associating a legal requirement, which defines an item to be implemented for compliance with a law or regulation, with evidence record information related to an evidence record necessary to indicate that compliance with the legal requirement has been implemented. The legal compliance support system analyzes the stored evidence record and presents the evidence record that satisfies the legal requirement as an evidence record candidate to a user through an output unit. The legal compliance support system receives the evidence record selected from the evidence record candidate by the user, associates the legal requirement satisfied by the evidence record with the evidence record selected from the evidence record candidate by the user, and registers the association as compliance record management information.

A biometric registration system receives personal information on a user, and control a first acquisition device to acquire first biometric data on the user; extracts a first feature amount from the first biometric data; registers pre-registration data in which the personal information and the first feature amount are associated with each other; controls, in a case where a registration procedure using a registration device is started, a second acquisition device to acquire second biometric data and third biometric data; extracts a second feature amount and a third feature amount from the second biometric data and the third biometric data; compares the first feature amount and the second feature amount to each other; and registers registration data in which the personal information included in the pre-registration data corresponding to the first feature amount that matches the second feature amount and the third feature amount are associated with each other.

The present invention addresses the problem of enabling the inheritance of skilled knowledge by generating a knowledge graph from a restoration work report and a skilled worker's work simulation in a virtual space, and appending skilled knowledge to the restoration work report using the knowledge graph and a Large Language Model (LLM). A work simulation system (110) allows a user to select, via an operation unit (105), a scene stored in a scene storage unit (120) in which a work simulation is to be performed within a virtual space (100). The system generates a knowledge graph based on a restoration work report stored in a restoration work report storage unit (140) and the work simulation, appends skilled knowledge to the restoration work report using the generated knowledge graph, and optionally determines standard work for the same case by using all knowledge graphs stored in a knowledge graph storage unit (130).

Embodiments of the present disclosure relate to a method and system for optimizing vehicle allocation in a transportation system. The method comprises receiving sensor values from a first set of vehicles of a plurality of vehicles. The method also comprises applying, using an AI model, an imputation technique on the sensor values to estimate missing sensor values corresponding to the second set of vehicles, and to generate a complete set of sensor values for the plurality of vehicles. Further, the method comprises determining an optimized vehicle plan for one or more routes of the transportation system based on the complete set of sensor values. The optimized vehicle plan comprises tripwise plan of vehicles with sensors and sensor-less vehicles for each route. Lastly, the method comprises allocating the plurality of vehicles to the one or more route at least based on the optimized vehicle plan.

A system for performing postural evaluation. The system comprises: a posture determination unit configured to receive motion and/or positional data relating to one or more parts of a user's body to determine a posture of the user; a task determination unit configured to use the determined posture and/or motion and/or positional data to determine a task being performed by the user; a posture evaluation unit configured to: retrieve a predetermined template posture corresponding to the determined task, and measure a difference between the determined posture of the user and the predetermined template posture; and a posture optimizer unit configured to: perform a mitigation action when the measured difference is greater than the a predetermined posture difference threshold.

An OAM radio wave transmitting and receiving system keeps an apparatus size from increasing by performing localized measurement of an OAM radio wave to acquire OAM radio wave information. A radio wave generating apparatus includes a controlling section and a radio wave transmitting section. The controlling section includes an OAM radio wave information setting section for generating a transmission radio wave signal according to an OAM mode order, a phase changing section for linearly changing a phase of the transmission radio wave signal over time depending on the OAM mode order, and a complex signal generating section for generating a complex signal from the transmission radio wave signal that has been changed in phase by the phase changing section and a reference signal. The radio wave transmitting section includes a complex signal converting section for breaking down a signal component of the complex signal into a real part and an imaginary part, a wireless processing section for generating a wireless signal from the signal component of the complex signal that has been broken down into the real part and the imaginary part, and an array antenna for transmitting the wireless signal as an OAM radio wave.

Once a technician detects and reports an equipment failure, diagnostic systems and methods herein automatically generate a diagnostic plan, detailing necessary parts, areas of interest, and actions to be taken. Using augmented reality (AR) indicators, a system guides the technician while a perception module analyzes their actions to recommend next steps. A planning component uses knowledge graph (KG) and LLM to create the diagnostic plan, without requiring extensive data labeling or model training. A tracking component enhances 3D detections by employing perception sensors and a 2D nested object detection model. A guiding component simplified processed for novice technicians by integrating 2D models and AR interactions to ensure efficient and accurate diagnostics.
