A secure computation system comprises at least five secure computation server apparatuses connected to each other via a network and performs secure computation on a value stored while being secret-shared, and each of the secure computation server apparatuses has a comparative verification part that compares values, which should be the same, received from at least three secure computation server apparatuses and that accepts a received value identical to at least another received value as a correct value.

SERVER DEVICE, CONFERENCE ASSISTANCE SYSTEM, CONFERENCE ASSISTANCE METHOD, AND PROGRAM (17799362)

Main Inventor

Shin NORIEDA

Brief explanation

The server device described in the abstract has two main components: an acquisition unit and an information provision unit. The acquisition unit is able to collect multiple attribute values for the same item by gathering profiles from different users using a conference assistance system. If there are items for which multiple attribute values have been set for the profile of a first participant in the conference, the information provision unit selects one or more attribute values from the available options. The selected attribute values are then provided to a second participant who is also participating in the same conference as the first participant. This allows the second participant to view the profile of the first participant, including the selected attribute values.

Abstract

The server device includes: an acquisition unit; and an information provision unit. The acquisition unit is capable of acquiring a plurality of attribute values for the same item when acquiring the respective profiles of a plurality of users using a conference assistance system. When items exist for which a plurality of attribute values have been set for the profile of a first participant participating in the conference among the plurality of users, the information provision unit selects at least one or more attribute values among the plurality of attribute values. The information provision unit provides, to a second participant participating in the same conference as the conference in which the first participant is participating, the profile of the first participant that includes the at least one or more attribute values thus selected.

IMAGING CONTROL SYSTEM, IMAGING CONTROL METHOD, CONTROL DEVICE, CONTROL METHOD, AND STORAGE MEDIUM (18216316)

Main Inventor

Keiichi CHONO

Brief explanation

The abstract describes a system and method for acquiring more images or quickly focused images. A control device collects information about the range captured by an imaging device and selects a focusing mode based on the assumed situation of the range. The control device then sends the selected mode to the imaging device. The imaging device receives this information and captures an image using the specified mode.

Abstract

To provide a system, a method and the like for acquiring more images or more quickly focused images. A control device acquires information regarding a situation of a range captured by an imaging device, determines a mode according to an assumed situation of the range captured by the imaging device among a plurality of focusing modes, and transmits designation information specifying the determined mode to the imaging device. The imaging device receives the designation information from the control device, and captures an image using the mode specified by the received designation information.

METHOD, DEVICE AND COMPUTER STORAGE MEDIUM OF COMMUNICATION (17908805)

Main Inventor

Gang WANG

Brief explanation

This abstract describes a method for improving communication between devices in different networks. The method involves determining if a switch should be made from one network device to another, and if so, sending a request to the first network device to perform the switch. This helps notify the network and improve performance during the switch.

Abstract

Embodiments of the present disclosure relate to methods, devices and computer readable media for communication. A method of communication comprises determining, at a terminal device, whether a switch is to be performed from a first network device of a first communication network to a second network device of a second communication network, the first and second communication networks being associated with first and second identities of the terminal device respectively; and in response to determining that the switch is to be performed, transmitting, to the first network device, a request for the switch from the first network device to the second network device. In this way, the switch can be notified to the network side and network performance during the switch can be enhanced.

COMMUNICATION SYSTEM (17626572)

Main Inventor

Chadi KHIRALLAH

Brief explanation

This abstract describes a communication system where a base station communicates with a user equipment (UE) through a cell using a Listen-Before-Talk (LBT) method. If the base station detects a failure in the LBT communication in any cell, it sends a signaling message to another node (such as a central unit or a core network node) indicating that a failure has occurred. This information is then used by the other node to manage the LBT communication with the UE, such as releasing resources or deactivating cells.

Abstract

A communication system is disclosed in which a base station performs Listen-Before-Talk (LBT) communication with an item of user equipment (UE) via at least one cell. When the base station of the UE detects a failure associated with the LBT communication in at least one cell, the base station transmits a signalling message to another node (e.g., a central unit, a master node, a secondary node, or a core network node), the signalling message comprising information indicating that LBT failure has been detected. The information is used by the other node in managing the LBT communication with the UE (e.g., releasing resources, deactivating cells, etc.).

QUANTUM DEVICE (18007772)

Main Inventor

Katsumi KIKUCHI

Brief explanation

The abstract describes a quantum device that can improve cooling performance. The device consists of a quantum chip that processes information using quantum states, and an interposer on which the quantum chip is mounted. The quantum chip is placed inside a recess in a sample stage that has a cooling function, and a part of the interposer is in contact with the sample stage. The quantum chip has two surfaces, with the first surface mounted on the interposer and the second surface in contact with the inner surface of the recess.

Abstract

Provided is a quantum device capable of improving cooling performance. A quantum device includes a quantum chip configured to perform information processing using a quantum state, and an interposer on which the quantum chip is mounted, and the quantum chip is arranged inside a recess  formed in a sample stage having a cooling function, and a part of the interposer is in contact with the sample stage. The quantum chip may have a first surface mounted on the interposer and a second surface opposite to the first surface, and at least a part of the second surface may be in contact with an inner surface of the recess.
