Abstract: A rotating ball valve may be employed in a liner hanger setting tool. A rotating ball member maintains contact with a valve seat throughout the operation of the rotating ball valve, thereby preventing debris from settling on the valve seat and compromising the integrity of a seal through a fluid flow path defined through the setting tool. The rotating ball valve may be actuated by selectively applying fluid pressure to the flow path, or by mechanical manipulation. Once the fluid flow path is closed, a latch may be activated to maintain the rotating ball valve in the closed configuration and a pressure may be applied against the closed rotating ball member. A downhole movement be induced by the applied pressure to drive an expansion cone through an expandable liner hanger, to secure a liner in the wellbore.

Abstract: Content items are rearranged within a digital collaboration space (e.g., a digital whiteboard) based on category metadata determined for the content items using one or more learning models. The content items are added to the digital collaboration space by one or more users. For each of the content items, category metadata is determined using a learning model that processes information associated with the content item. A rearrangement of the content items is determined based on the category metadata determined for each of the content items. The content items, rearranged according to the rearrangement, are then output to a layer of the digital collaboration space. Other rearrangements of the content items can be determined based on non-category metadata associated with the content items, and the content items, rearranged according to those other rearrangements, can be output to other layers of the digital collaboration space.

Abstract: One disclosed example system includes a reception room meeting device configured for establishing a video conference with a device associated with a remote receptionist. The reception room meeting device sends a request for a video meeting with one of a plurality of candidate remote receptionists in response to receiving an activation signal triggered by a visitor to a reception area, and establishes the video meeting with a device associated with one remote receptionist selected based on the request. The system further includes a virtual receptionist system configured to access visitor data obtained by various input devices at the reception area, and determine the status of the visitor based on the visitor data. The virtual receptionist system further transmits the status of the visitor to the device associated with the selected remote receptionist to facilitate the check-in process.

Abstract: A method for voltage balancing of series connected capacitors, wherein a voltage in an intermediate circuit of an electric circuit can be easily and safely balanced between a plurality of series connected capacitors and thus these components are operated safely in terms of their voltage strength. This problem is solved in that the voltage balancing is accomplished in that, in a first step of the method, an at least partial discharging of a first or a second capacitor occurs across a first or second winding of a transformer, while thanks to the action of the transformer a current is induced in a second step of the method in the second or first winding which charges the second or first capacitor as a charging current.
