摘要:
Components of a firearm having a bolt with locking lugs improve shooting accuracy, due to increased coaxial alignment between the bolt, the cartridge, the receiver, and/or the barrel of a firearm. The receiver inner surface is shaped for lug-cleaning and for close tolerance/mating with the lugs only in the locked position and also with a non-threaded, axial surface of the barrel. Thus, the mating surfaces that are instrumental and/or that mainly control coaxial alignment of the receiver, bolt, and barrel are located between the lug stops and the threaded end of the receiver. The lugs may be axially curved or otherwise axially non-linear to tolerate dirt and other debris in a field environment.

Firearms, and components of firearms, improve shooting accuracy, due to increased coaxial alignment between the receiver and the barrel of the firearm. The outer surface of the barrel and the receiver inner surface feature extremely-tight-tolerance/press-fit mating of one or more outer axial mating surfaces of the barrel with one or more axial portions of the receiver inner surface. The extremely-tight-tolerance/press-fit axial mating surfaces may be distal of, proximal of, in-between, and/or otherwise outside and separate from the threads or conventional connection means for connecting the barrel to the receiver.

According to an implementation of the present specification there is provided an apparatus for creating a hybrid image. The apparatus comprises: a first light source configured to emit a first light in a first direction; a reflector disposed to intercept the first light and configured to at least partially reflect the first light in an output direction to produce a reflected first light. The apparatus also comprises a second light source configured to emit a second light, the reflector configured to at least partially transmit the second light in the output direction to produce a transmitted second light. The apparatus also comprises an input terminal configured to receive an input used to control one or more of the first light source and the second light source. The hybrid image comprises a combination of the reflected first light and the transmitted second light.

A gaming environment may be established, by executing a game engine module to provide an interactive game instance, and instantiating a state machine instance using one or both of a state machine client module or a state machine server module. In an example, during execution of the game engine module, scripting commands within a state machine definition may be parsed and executed to obtain information indicative of one or more of a state of an in-game object or a state transition of an in-game object. An in-game object may be controlled within the game instance via the state machine using at least a portion of the information obtained from parsing and executing the scripting commands. Use of the state machine definitions in conjunction with the scripting commands may enable representation of complex scenarios for virtual objects and events in the gaming environment in a simplified format.
摘要:
An API for prefetching map data receives a prefetch request for an indicated geographic area from a software application. In response, the API retrieves map data corresponding to the indicated geographic area from a map data provider and stores the map data in a map data cache without causing a digital map based on the map data to be displayed on the display device. The map data cache is accessible to the software application only via the API. Subsequently to storing the map data in the map data cache, the API receives a request to render the digital map from the software application and, in response to the request to render the map image, renders the map image for display on a display device using the map data stored in the map data cache.

Disclosed in some examples is a method of providing a computer-implemented game, the method includes rendering a display of a virtual in-game environment comprising an unlocked area and a locked area, an in-game player character controlled by a player of the game having access to the unlocked areas but being restricted from accessing the locked area; and using one or more processors, applying a visual effect to the locked area to distinguish the locked area from the unlocked area, the visual effect revealing one or more aspects of the unlocked area.

An electronic device includes a requesting application and a hosting application. When the requesting application requests permission from the hosting application to access a category of data, the device identifies the requesting application and the permission request. The device awaits a user input to determine whether the user will permit the requesting application's request to be granted.

Methods and systems for providing routing information to a user are disclosed. Based on a request for routing information between an origin and destination for a travel objective, wireless coverage data for the geographic area associated with the travel objective is received. A graph model for determining routes between the origin and destination is adjusted based at least in part on the wireless coverage data. According to particular aspects of the present disclosure, the graph model can be adjusted based on the wireless coverage data and at least additional parameter such as estimated trip time, average speed, distance, favored routes or traffic information. User information can be optionally provided and used to emphasize or deemphasize wireless coverage data in the determination of the route for the travel objective.
