Abstract: The present invention refers to the field of transactional data management. The invention provides a transactional semantic concurrency control system for managing a database, wherein the system comprises a data store engine which is adapted to manage the database comprising value rows, and each value row comprising a primary key uniquely identifying each row, at least one semantic column and a commit timestamp; wherein the data store engine is further adapted to manage operation rows, which are rows comprising a primary key, at least one operation to be applied over at least one semantic column of a value row identified by the primary key, and a commit timestamp; store the value rows and the operation rows; generate an operation row when it receives an operation that inserts, updates, upserts, and/or deletes a row of the database with the commit timestamp of the operation; and apply the operations of at least one operation row when a trigger condition is satisfied.

Abstract: Head-mounted display systems with power saving functionality are disclosed. The systems can include a frame configured to be supported on the head of the user. The systems can also include a head-mounted display disposed on the frame, one or more sensors, and processing electronics in communication with the display and the one or more sensors. In some implementations, the processing electronics can be configured to cause the system to reduce power of one or more components in response to at least in part on a determination that the frame is in a certain position (e.g., upside-down or on top of the head of the user). In some implementations, the processing electronics can be configured to cause the system to reduce power of one or more components in response to at least in part on a determination that the frame has been stationary for at least a threshold period of time.

Abstract: A method and system for producing at least one byproduct from spent grains, such as Brewer's Spent Grains or Distiller's Spent Grains. In one embodiment, the spent grains are preserved via a preservation treatment before being put through a cellulase treatment. The cellulase treated spent grains are then filtered to produce at least one byproduct.

Abstract: In a substrate processing system, such as a chemical mechanical system, updated controller configuration data is obtained for a plurality of liquid flow controllers of the substrate processing system. Each of a plurality of liquid flow controllers (LFCs) coupled to an Ethernet for Control Automation Technology (EtherCAT) bus automatically downloads a copy of the updated controller configuration data through the EtherCAT bus. Each of the plurality of liquid flow controllers controls fluid flow of a separate fluid line from a plurality of fluid lines in the substrate processing system, fluid flow through the plurality of fluid lines is controlled using the plurality of liquid flow controllers having the updated controller configuration data.

Abstract: A virtual or augmented reality display system can include a first sensor to provide measurements of a user's head pose over time and a processor to estimate the user's head pose based on at least one head pose measurement and based on at least one calculated predicted head pose. The processor can combine the head pose measurement and the predicted head pose using one or more gain factors. The one or more gain factors may vary based upon the user's head pose position within a physiological range of movement.

The image input device can include a light source and a spatial light modulator. The system can also include a controller that determines that no virtual content is being displayed to the user and compares the ambient light to display light to determine if a light source shutoff criterion is satisfied. If the light source shutoff criterion is satisfied, the controller can turn off the light source.

Abstract: A virtual testing platform for a cruise ship is described. An example platform obtains information indicative of passengers of a sailing of a cruise ship, the information indicating assignment of the passengers to respective cabins of the cruise ship. A first subset of the passengers who represent virtual passengers and a second subset of the passengers who represent real-world passengers are determined, with the virtual passengers being indicated as not having arrived to board the cruise ship, such that the virtual passengers are not counted as being embarked on the cruise ship. Requests for activities received from applications are responded to, with the responses indicating whether the bookings were successful, and with each request being determined as being associated with a virtual passenger or a real-world passenger. The successful bookings associated with virtual passengers are triggered for cancellation.
