Publication number: 20240121162Abstract: A simulation environment (e.g., multi-player game) hosted by a provider network may implement componentized entities to reduce the amount of resource usage for a simulation (e.g., by reducing the amount of input/state data transmitted through the use of dynamically changing input structures). A user may add or remove any number of components to an entity that is simulated at the local client device. When inputs are received for one or more components, values for predictive states are locally determined for each component. An input packet is generated and sent to the provider network, which includes the inputs as well as data that is based on the values for the locally predicted states (e.g., a fingerprint or other unique ID). If necessary, a correction packet may be generated at the provider network and sent back to the client.Type: ApplicationFiled: December 7, 2023Publication date: April 11, 2024Applicant: Amazon Technologies, Inc.Inventors: Karl Berg, Joseph Pease, Neema Teymory, Alan Krause

Patent number: 10988961Abstract: A safety device for a motor vehicle includes a bonnet with an open and closed position, a bonnet lock with a lock retainer and a rotary latch, and an electric drive which shifts the rotary latch from a main locking position into a preliminary locking position. The lock retainer has an actuator, wherein in a first position of the actuator and in the preliminary locking position of the rotary latch, the lock retainer engages with the rotary latch and the bonnet is locked, and in a second position of the actuator, the lock retainer is released by the rotary latch and the bonnet is unlocked. The bonnet is coupled to the actuator such that in the preliminary locking position of the rotary latch a displacement of the bonnet towards the closed position of the bonnet causes a displacement of the actuator from the first position into the second position.Type: GrantFiled: September 30, 2016Date of Patent: April 27, 2021Assignee: Kiekert AGInventors: Karl Krause, Thorsten Nottebaum, Johannes Theodor Menke, Thorsten Bendel
