An example outdoor mounted device includes a first battery configured to operate at a low temperature range that at least includes negative 20 Celsius; a second battery configured to operate at a high temperature range; a temperature sensor; and processing circuitry configured to: determine, based on data received from the temperature sensors, a current temperature; responsive to determining that the current temperature is within the low temperature range, cause one or more components of the computing device to operate using electrical energy sourced from the first battery; and responsive to determining that the current temperature is within the high temperature range, cause the one or more components of the computing device to operate using electrical energy sourced from the second battery.

Multiple battery cell architecture for outdoor mounted computing devices

This specification describes technologies relating to software execution. A computing device includes a processor. An operating system includes an execution environment in which applications can execute computer-specific commands. A web-browser application includes a scripting environment for interpreting scripted modules. The web-browser application further includes a native environment in which native modules can execute computer-specific commands. The web-browser application further includes an interface between the scripting environment and the native environment. The interface includes functions to asynchronously pass data objects by value, from one of the scripting environment and the native environment, to the other of the scripting environment and the native environment.

Asynchronous message passing

Systems, methods and articles of manufacture for optimized rendering of multimedia content as described herein. An embodiment includes identifying one or more content layers for display and promoting the multimedia content layer for display over all layers of the one or more content layers, when no content is to be displayed over the multimedia content layer. Another embodiment includes identifying one or more content layers for display and displaying a bitmap representing a multimedia content layer directly on a display device, when no content is to be displayed over the multimedia content layer.

Optimized rendering of multimedia content

Systems and methods for rendering web content in a browser are described herein. An embodiment includes a web rendering engine in a rendering engine process to generate one or more requests to selectively redraw one or more regions of content retrieved by a browser process. A renderview then generates a bitmap based on the requests and content retrieved by the browser process. The bitmap may then be stored by the renderview in a shared memory area where it may be accessed by a renderview host in the browser process. The renderview host may then provide the bitmap to a backing store associated with a display device for display to a user. In another embodiment, the shared memory area between the browser process and the rendering engine process may be used to achieve efficient scrolling of a web page through rate limited rendering of content.

Methods and systems for rendering in a multi-process browser using a shared memory area

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for an extensible browser plugin interface. In one aspect, a method includes receiving, at a browser plugin interface, an interface request from a plugin, where the interface request includes an interface identifier string that identifies a particular interface; determining, using the interface identifier string, whether the particular interface is supported by the browser; and if it is determined that the particular interface is supported by the browser, returning to the plugin a virtual function table (vtable) of one or more functions, wherein the vtable is associated with the particular interface identified by the interface request.

Extensible browser plugin interface

Systems and methods for multi-process browser architecture are described herein. In an embodiment, a system for providing multi-process browser architecture includes at least one rendering process for each browser instance that renders a content area; and at least one browser process that communicates with one or a plurality of rendering engine processes. In another embodiment, a method for providing a multi-process browser architecture includes instantiating a unique rendering process for each content area instance and instantiating a unique browser process. In this way browsers may avoid the effects of faulty processes affecting other browser processes. This may improve user efficiency while enhancing user experience.

Multi-process browser architecture

Embodiments relate to content resizing and caching in multi-process browser architecture. An embodiment includes initiating a rendering engine process and a browser process, receiving a request to resize content, providing the request to the rendering engine process, waiting to allow the rendering engine process to render an updated bitmap associated with the content and displaying the updated bitmap synchronously if the updated bitmap is produced during the waiting step. Another embodiment includes, receiving an input associated with the status of a tab, determining if the tab is a background tab or a foreground tab based on the receiving step, checking a cache for a bitmap of content associated with the tab if the tab has changed status to a foreground tab, and displaying the contents of the cache in the tab if the cache includes the bitmap of content previously associated with the tab.
