Abstract: A normally closed disc clamp system includes a housing with a rotating disc, a brake ring and a pressure-enhancing ring arranged therein. When only a first chamber is supplied with fluid, the fluid pushes the brake ring to release the rotating disc. When only a second chamber is fed with fluid, the fluid pushes the brake ring to keep the rotating disc in the braking state, and pushes the pressure-enhancing ring to compress an elastic unit. The energy generated by the compression of the elastic unit acts on the brake ring through the fluid, so that the brake ring achieves a double pressurization effect. If the action of the fluid fails, the brake ring can still provide a braking effect to the rotating disc through the elastic unit to improve operational safety. Further, the present invention further provides a rotating table using the normally closed disc clamp system.

Abstract: An online system, for example, a multi-tenant system interacts with various conversation channels, for example, various telephony services and artificial intelligence provider systems that perform artificial intelligence based analysis of conversations. The analysis of the conversation determines additional information describing the conversation, for example, sentiment of an utterance of the conversation, entities mentioned in an utterance of the conversation, intent of an utterance of the conversation, and so on. The online system stores the information describing conversations using a normalized representation that conforms to a unified conversation schema. Various applications may use the result of the analysis obtained from the AI provider systems to take further action, for example, recommend a specific workflow to an agent that is a participant in the conversation.

Abstract: A multi-level boost apparatus. Voltage allocation among N first switches is achieved by arranging the N voltage dividing modules. It is prevented that the second one to the N-th one of the first switches break down and fail due to overvoltage. By arranging an (i?1)-th clamp branch at a common node between an (i?1)-th second switch and an i-th second switch, a voltage bore by the i-th second switch is clamped at a difference between a voltage across the fourth branch (namely, an output voltage of the multi-level boost apparatus) and a voltage across the corresponding clamp branch. The risk is avoided that a second one to the N-th one of the second switches break down due to overvoltage at an instant of being powered, in a case that the input voltage is low.
