Patent Application
20240345895
Examples of the present disclosure relate generally to power attribution and throttling on mobile devices. More particularly, but not by way of limitation, examples of the present disclosure relate to a mobile device such as a virtual reality (VR), mixed reality (MR), or an augmented reality (AR) mobile device where the VR, MR, or AR mobile device attributes power consumption and temperature generation to processes and throttles processes that exceed their power consumption or temperature generation budget.
Users increasingly want mobile devices to operate in a more user-friendly manner with more functions. However, often, the mobile devices are susceptible to overheating and often the mobile devices have limited batteries to provide additional functions.
In the drawings, which are not necessarily drawn to scale, like numerals may describe similar components in different views. To easily identify the discussion of any particular element or act, the most significant digit or digits in a reference number refer to the figure number in which that element is first introduced. Some non-limiting examples are illustrated in the figures of the accompanying drawings in which:
The description that follows includes systems, methods, techniques, instruction sequences, and computing machine program products that embody illustrative examples of the disclosure. In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide an understanding of various examples of the inventive subject matter. It will be evident, however, to those skilled in the art, that examples of the inventive subject matter may be practiced without these specific details. In general, well-known instruction instances, protocols, structures, and techniques are not necessarily shown in detail.
The term mobile device is used as an illustrative device; however, one skilled in the art will recognize that the methods, systems, and computer readable medium disclosed herein are applicable to other mobile devices such as wearable devices or non-wearable devices including AR, VR and MR head-wearable devices.
A technical challenge is how to increase the usefulness of a battery 918 on a mobile device and how to reduce the temperature generation 1010. The technical challenge is addressed by, referring to
In some examples, the designer of the applications 928, 944 uses the information from the operating system 942 regarding the power consumption 1004 and temperature generation 1010 to reduce the power consumption 1004 or the temperature generation 1010. For example, there may be a component of the system 900 that is particularly vulnerable to overheating so the application 928, 944 may be designed to reduce the use of the component.
Each user system 102 may include multiple user devices, such as a computing device 114, head-wearable apparatus 116, and a computer client device 118 that are communicatively connected to exchange data and messages.
An interaction client 104 interacts with other interaction clients 104 and with the interaction server system 110 via the network 108. The data exchanged between the interaction clients 104 (e.g., interactions 120) and between the interaction clients 104 and the interaction server system 110 includes functions (e.g., commands to invoke functions) and payload data (e.g., text, audio, video, or other multimedia data).
The interaction server system 110 provides server-side functionality via the network 108 to the interaction clients 104. While certain functions of the interaction system 100 are described herein as being performed by either an interaction client 104 or by the interaction server system 110, the location of certain functionality either within the interaction client 104 or the interaction server system 110 may be a design choice. For example, it may be technically preferable to initially deploy particular technology and functionality within the interaction server system 110 but to later migrate this technology and functionality to the interaction client 104 where a user system 102 has sufficient processing capacity.
The interaction server system 110 supports various services and operations that are provided to the interaction clients 104. Such operations include transmitting data to, receiving data from, and processing data generated by the interaction clients 104. This data may include message content, client device information, geolocation information, media augmentation and overlays, message content persistence conditions, social network information, and live event information. Data exchanges within the interaction system 100 are invoked and controlled through functions available via user interfaces (UIs) of the interaction clients 104.
Turning now specifically to the interaction server system 110, an Application Program Interface (API) server 122 is coupled to and provides programmatic interfaces to interaction servers 124, making the functions of the interaction servers 124 accessible to interaction clients 104, other applications 106 and third-party server 112. The interaction servers 124 are communicatively coupled to a database server 126, facilitating access to a database 128 that stores data associated with interactions processed by the interaction servers 124. Similarly, a web server 130 is coupled to the interaction servers 124 and provides web-based interfaces to the interaction servers 124. To this end, the web server 130 processes incoming network requests over the Hypertext Transfer Protocol (HTTP) and several other related protocols.
The Application Program Interface (API) server 122 receives and transmits interaction data (e.g., commands and message payloads) between the interaction servers 124 and the client systems (and, for example, interaction clients 104 and other application 106) and the third-party server 112. Specifically, the Application Program Interface (API) server 122 provides a set of interfaces (e.g., routines and protocols) that can be called or queried by the interaction client 104 and other applications 106 to invoke functionality of the interaction servers 124. The Application Program Interface (API) server 122 exposes various functions supported by the interaction servers 124, including account registration; login functionality; the sending of interaction data, via the interaction servers 124, from a particular interaction client 104 to another interaction client 104; the communication of media files (e.g., images or video) from an interaction client 104 to the interaction servers 124; the settings of a collection of media data (e.g., a story); the retrieval of a list of friends of a user of a user system 102; the retrieval of messages and content; the addition and deletion of entities (e.g., friends) to an entity graph (e.g., a social graph); the location of friends within a social graph; and opening an application event (e.g., relating to the interaction client 104). The interaction servers 124 host multiple systems and subsystems, described below with reference to
Returning to the interaction client 104, features and functions of an external resource (e.g., a linked application 106 or applet) are made available to a user via an interface of the interaction client 104. In this context, “external” refers to the fact that the application 106 or applet is external to the interaction client 104. The external resource is often provided by a third party but may also be provided by the creator or provider of the interaction client 104. The interaction client 104 receives a user selection of an option to launch or access features of such an external resource. The external resource may be the application 106 installed on the user system 102 (e.g., a “native app”), or a small-scale version of the application (e.g., an “applet”) that is hosted on the user system 102 or remote of the user system 102 (e.g., on third-party servers 112). The small-scale version of the application includes a subset of features and functions of the application (e.g., the full-scale, native version of the application) and is implemented using a markup-language document. In some examples, the small-scale version of the application (e.g., an “applet”) is a web-based, markup-language version of the application and is embedded in the interaction client 104. In addition to using markup-language documents (e.g., a .*ml file), an applet may incorporate a scripting language (e.g., a .*js file or a .json file) and a style sheet (e.g., a .*ss file).
In response to receiving a user selection of the option to launch or access features of the external resource, the interaction client 104 determines whether the selected external resource is a web-based external resource or a locally-installed application 106. In some cases, applications 106 that are locally installed on the user system 102 can be launched independently of and separately from the interaction client 104, such as by selecting an icon corresponding to the application 106 on a home screen of the user system 102. Small-scale versions of such applications can be launched or accessed via the interaction client 104 and, in some examples, no or limited portions of the small-scale application can be accessed outside of the interaction client 104. The small-scale application can be launched by the interaction client 104 receiving, from a third-party server 112 for example, a markup-language document associated with the small-scale application and processing such a document.
In response to determining that the external resource is a locally-installed application 106, the interaction client 104 instructs the user system 102 to launch the external resource by executing locally-stored code corresponding to the external resource. In response to determining that the external resource is a web-based resource, the interaction client 104 communicates with the third-party servers 112 (for example) to obtain a markup-language document corresponding to the selected external resource. The interaction client 104 then processes the obtained markup-language document to present the web-based external resource within a user interface of the interaction client 104.
The interaction client 104 can notify a user of the user system 102, or other users related to such a user (e.g., “friends”), of activity taking place in one or more external resources. For example, the interaction client 104 can provide participants in a conversation (e.g., a chat session) in the interaction client 104 with notifications relating to the current or recent use of an external resource by one or more members of a group of users. One or more users can be invited to join in an active external resource or to launch a recently-used but currently inactive (in the group of friends) external resource. The external resource can provide participants in a conversation, each using respective interaction clients 104, with the ability to share an item, status, state, or location in an external resource in a chat session with one or more members of a group of users. The shared item may be an interactive chat card with which members of the chat can interact, for example, to launch the corresponding external resource, view specific information within the external resource, or take the member of the chat to a specific location or state within the external resource. Within a given external resource, response messages can be sent to users on the interaction client 104. The external resource can selectively include different media items in the responses, based on a current context of the external resource.
The interaction client 104 can present a list of the available external resources (e.g., applications 106 or applets) to a user to launch or access a given external resource. This list can be presented in a context-sensitive menu. For example, the icons representing different ones of the application 106 (or applets) can vary based on how the menu is launched by the user (e.g., from a conversation interface or from a non-conversation interface).
An image processing system 202 provides various functions that enable a user to capture and augment (e.g., annotate or otherwise modify or edit) media content associated with a message.
A camera system 204 includes control software (e.g., in a camera application) that interacts with and controls hardware camera hardware (e.g., directly or via operating system controls) of the user system 102 to modify and augment real-time images captured and displayed via the interaction client 104.
The augmentation system 206 provides functions related to the generation and publishing of augmentations (e.g., media overlays) for images captured in real-time by cameras of the user system 102 or retrieved from memory of the user system 102. For example, the augmentation system 206 operatively selects, presents, and displays media overlays (e.g., an image filter or an image lens) to the interaction client 104 for the augmentation of real-time images received via the camera system 204 or stored images retrieved from memory 502 of a user system 102. These augmentations are selected by the augmentation system 206 and presented to a user of an interaction client 104, based on a number of inputs and data, such as for example:
An augmentation may include audio and visual content and visual effects. Examples of audio and visual content include pictures, texts, logos, animations, and sound effects. An example of a visual effect includes color overlaying. The audio and visual content or the visual effects can be applied to a media content item (e.g., a photo or video) at user system 102 for communication in a message, or applied to video content, such as a video content stream or feed transmitted from an interaction client 104. As such, the image processing system 202 may interact with, and support, the various subsystems of the communication system 208, such as the messaging system 210 and the video communication system 212.
A media overlay may include text or image data that can be overlaid on top of a photograph taken by the user system 102 or a video stream produced by the user system 102. In some examples, the media overlay may be a location overlay (e.g., Venice beach), a name of a live event, or a name of a merchant overlay (e.g., Beach Coffee House). In further examples, the image processing system 202 uses the geolocation of the user system 102 to identify a media overlay that includes the name of a merchant at the geolocation of the user system 102. The media overlay may include other indicia associated with the merchant. The media overlays may be stored in the databases 128 and accessed through the database server 126.
The image processing system 202 provides a user-based publication platform that enables users to select a geolocation on a map and upload content associated with the selected geolocation. The user may also specify circumstances under which a particular media overlay should be offered to other users. The image processing system 202 generates a media overlay that includes the uploaded content and associates the uploaded content with the selected geolocation.
The augmentation creation system 214 supports augmented reality developer platforms and includes an application for content creators (e.g., artists and developers) to create and publish augmentations (e.g., augmented reality experiences) of the interaction client 104. The augmentation creation system 214 provides a library of built-in features and tools to content creators including, for example custom shaders, tracking technology, and templates.
In some examples, the augmentation creation system 214 provides a merchant-based publication platform that enables merchants to select a particular augmentation associated with a geolocation via a bidding process. For example, the augmentation creation system 214 associates a media overlay of the highest bidding merchant with a corresponding geolocation for a predefined amount of time.
A communication system 208 is responsible for enabling and processing multiple forms of communication and interaction within the interaction system 100 and includes a messaging system 210, an audio communication system 216, and a video communication system 212. The messaging system 210 is responsible for enforcing the temporary or time-limited access to content by the interaction clients 104. The messaging system 210 incorporates multiple timers (e.g., within an ephemeral timer system 218) that, based on duration and display parameters associated with a message or collection of messages (e.g., a story), selectively enable access (e.g., for presentation and display) to messages and associated content via the interaction client 104. Further details regarding the operation of the ephemeral timer system 218 are provided below. The audio communication system 216 enables and supports audio communications (e.g., real-time audio chat) between multiple interaction clients 104. Similarly, the video communication system 212 enables and supports video communications (e.g., real-time video chat) between multiple interaction clients 104.
A user management system 220 is operationally responsible for the management of user data and profiles, and includes a social network system 222 that maintains information regarding relationships between users of the interaction system 100.
A collection management system 224 is operationally responsible for managing sets or collections of media (e.g., collections of text, image video, and audio data). A collection of content (e.g., messages, including images, video, text, and audio) may be organized into an “event gallery” or an “event story.” Such a collection may be made available for a specified time period, such as the duration of an event to which the content relates. For example, content relating to a music concert may be made available as a “story” for the duration of that music concert. The collection management system 224 may also be responsible for publishing an icon that provides notification of a particular collection to the user interface of the interaction client 104. The collection management system 224 includes a curation function that allows a collection manager to manage and curate a particular collection of content. For example, the curation interface enables an event organizer to curate a collection of content relating to a specific event (e.g., delete inappropriate content or redundant messages). Additionally, the collection management system 224 employs machine vision (or image recognition technology) and content rules to curate a content collection automatically. In certain examples, compensation may be paid to a user to include user-generated content into a collection. In such cases, the collection management system 224 operates to automatically make payments to such users to use their content.
A map system 226 provides various geographic location functions and supports the presentation of map-based media content and messages by the interaction client 104. For example, the map system 226 enables the display of user icons or avatars (e.g., stored in profile data 302) on a map to indicate a current or past location of “friends” of a user, as well as media content (e.g., collections of messages including photographs and videos) generated by such friends, within the context of a map. For example, a message posted by a user to the interaction system 100 from a specific geographic location may be displayed within the context of a map at that particular location to “friends” of a specific user on a map interface of the interaction client 104. A user can furthermore share his or her location and status information (e.g., using an appropriate status avatar) with other users of the interaction system 100 via the interaction client 104, with this location and status information being similarly displayed within the context of a map interface of the interaction client 104 to selected users.
A game system 228 provides various gaming functions within the context of the interaction client 104. The interaction client 104 provides a game interface providing a list of available games that can be launched by a user within the context of the interaction client 104 and played with other users of the interaction system 100. The interaction system 100 further enables a particular user to invite other users to participate in the play of a specific game by issuing invitations to such other users from the interaction client 104. The interaction client 104 also supports audio, video, and text messaging (e.g., chats) within the context of gameplay, provides a leaderboard for the games, and also supports the provision of in-game rewards (e.g., coins and items).
An external resource system 230 provides an interface for the interaction client 104 to communicate with remote servers (e.g., third-party servers 112) to launch or access external resources, i.e., applications or applets. Each third-party server 112 hosts, for example, a markup language (e.g., HTML5) based application or a small-scale version of an application (e.g., game, utility, payment, or ride-sharing application). The interaction client 104 may launch a web-based resource (e.g., application) by accessing the HTML5 file from the third-party servers 112 associated with the web-based resource. Applications hosted by third-party servers 112 are programmed in JavaScript leveraging a Software Development Kit (SDK) provided by the interaction servers 124. The SDK includes Application Programming Interfaces (APIs) with functions that can be called or invoked by the web-based application. The interaction servers 124 host a JavaScript library that provides a given external resource access to specific user data of the interaction client 104. HTML5 is an example of technology for programming games, but applications and resources programmed based on other technologies can be used.
To integrate the functions of the SDK into the web-based resource, the SDK is downloaded by the third-party server 112 from the interaction servers 124 or is otherwise received by the third-party server 112. Once downloaded or received, the SDK is included as part of the application code of a web-based external resource. The code of the web-based resource can then call or invoke certain functions of the SDK to integrate features of the interaction client 104 into the web-based resource.
The SDK stored on the interaction server system 110 effectively provides the bridge between an external resource (e.g., applications 106 or applets) and the interaction client 104. This gives the user a seamless experience of communicating with other users on the interaction client 104 while also preserving the look and feel of the interaction client 104. To bridge communications between an external resource and an interaction client 104, the SDK facilitates communication between third-party servers 112 and the interaction client 104. A Web ViewJavaScriptBridge running on a user system 102 establishes two one-way communication channels between an external resource and the interaction client 104. Messages are sent between the external resource and the interaction client 104 via these communication channels asynchronously. Each SDK function invocation is sent as a message and callback. Each SDK function is implemented by constructing a unique callback identifier and sending a message with that callback identifier.
By using the SDK, not all information from the interaction client 104 is shared with third-party servers 112. The SDK limits which information is shared based on the needs of the external resource. Each third-party server 112 provides an HTML5 file corresponding to the web-based external resource to interaction servers 124. The interaction servers 124 can add a visual representation (such as a box art or other graphic) of the web-based external resource in the interaction client 104. Once the user selects the visual representation or instructs the interaction client 104 through a GUI of the interaction client 104 to access features of the web-based external resource, the interaction client 104 obtains the HTML5 file and instantiates the resources to access the features of the web-based external resource.
The interaction client 104 presents a graphical user interface (e.g., a landing page or title screen) for an external resource. During, before, or after presenting the landing page or title screen, the interaction client 104 determines whether the launched external resource has been previously authorized to access user data of the interaction client 104. In response to determining that the launched external resource has been previously authorized to access user data of the interaction client 104, the interaction client 104 presents another graphical user interface of the external resource that includes functions and features of the external resource. In response to determining that the launched external resource has not been previously authorized to access user data of the interaction client 104, after a threshold period of time (e.g., 3 seconds) of displaying the landing page or title screen of the external resource, the interaction client 104 slides up (e.g., animates a menu as surfacing from a bottom of the screen to a middle or other portion of the screen) a menu for authorizing the external resource to access the user data. The menu identifies the type of user data that the external resource will be authorized to use. In response to receiving a user selection of an accept option, the interaction client 104 adds the external resource to a list of authorized external resources and allows the external resource to access user data from the interaction client 104. The external resource is authorized by the interaction client 104 to access the user data under an OAuth 2 framework.
The interaction client 104 controls the type of user data that is shared with external resources based on the type of external resource being authorized. For example, external resources that include full-scale applications (e.g., an application 106) are provided with access to a first type of user data (e.g., two-dimensional avatars of users with or without different avatar characteristics). As another example, external resources that include small-scale versions of applications (e.g., web-based versions of applications) are provided with access to a second type of user data (e.g., payment information, two-dimensional avatars of users, three-dimensional avatars of users, and avatars with various avatar characteristics). Avatar characteristics include different ways to customize a look and feel of an avatar, such as different poses, facial features, clothing, and so forth.
An advertisement system 232 operationally enables the purchasing of advertisements by third parties for presentation to end-users via the interaction clients 104 and also handles the delivery and presentation of these advertisements.
The power and temperature attribution system 234 supports system 900 for power and temperature attribution on mobile devices. In one example, the power and temperature system 234 maintains power consumption 1004 and temperature generation 1010 information for different resources 1002 of the system 900. The system 900 accesses the information via the wireless module 904, in accordance with some examples. The power and temperature attribution system 234 may act as an intermediary for sending data between the computing device 114 and the head-wearable apparatus 116 where the system 900 is part of the head-wearable apparatus 116. In some examples, the power and temperature attribution system 234 performs one or more functions described in conjunction with the system 900.
The database 304 includes message data stored within a message table 306. This message data includes, for any particular message, at least message sender data, message recipient (or receiver) data, and a payload. Further details regarding information that may be included in a message, and included within the message data stored in the message table 306, are described below with reference to
An entity table 308 stores entity data, and is linked (e.g., referentially) to an entity graph 310 and profile data 302. Entities for which records are maintained within the entity table 308 may include individuals, corporate entities, organizations, objects, places, events, and so forth. Regardless of entity type, any entity regarding which the interaction server system 110 stores data may be a recognized entity. Each entity is provided with a unique identifier, as well as an entity type identifier (not shown).
The entity graph 310 stores information regarding relationships and associations between entities. Such relationships may be social, professional (e.g., work at a common corporation or organization), interest-based, or activity-based, merely for example. Certain relationships between entities may be unidirectional, such as a subscription by an individual user to digital content of a commercial or publishing user (e.g., a newspaper or other digital media outlet, or a brand). Other relationships may be bidirectional, such as a “friend” relationship between individual users of the interaction system 100.
Certain permissions and relationships may be attached to each relationship, and also to each direction of a relationship. For example, a bidirectional relationship (e.g., a friend relationship between individual users) may include authorization for the publication of digital content items between the individual users, but may impose certain restrictions or filters on the publication of such digital content items (e.g., based on content characteristics, location data or time of day data). Similarly, a subscription relationship between an individual user and a commercial user may impose different degrees of restrictions on the publication of digital content from the commercial user to the individual user, and may significantly restrict or block the publication of digital content from the individual user to the commercial user. A particular user, as an example of an entity, may record certain restrictions (e.g., by way of privacy settings) in a record for that entity within the entity table 308. Such privacy settings may be applied to all types of relationships within the context of the interaction system 100, or may selectively be applied to certain types of relationships.
The profile data 302 stores multiple types of profile data about a particular entity. The profile data 302 may be selectively used and presented to other users of the interaction system 100 based on privacy settings specified by a particular entity. Where the entity is an individual, the profile data 302 includes, for example, a user name, telephone number, address, settings (e.g., notification and privacy settings), as well as a user-selected avatar representation (or collection of such avatar representations). A particular user may then selectively include one or more of these avatar representations within the content of messages communicated via the interaction system 100, and on map interfaces displayed by interaction clients 104 to other users. The collection of avatar representations may include “status avatars,” which present a graphical representation of a status or activity that the user may select to communicate at a particular time.
Where the entity is a group, the profile data 302 for the group may similarly include one or more avatar representations associated with the group, in addition to the group name, members, and various settings (e.g., notifications) for the relevant group.
The database 304 also stores augmentation data, such as overlays or filters, in an augmentation table 312. The augmentation data is associated with and applied to videos (for which data is stored in a video table 314) and images (for which data is stored in an image table 316).
Filters, in some examples, are overlays that are displayed as overlaid on an image or video during presentation to a recipient user. Filters may be of various types, including user-selected filters from a set of filters presented to a sending user by the interaction client 104 when the sending user is composing a message. Other types of filters include geolocation filters (also known as geo-filters), which may be presented to a sending user based on geographic location. For example, geolocation filters specific to a neighborhood or special location may be presented within a user interface by the interaction client 104, based on geolocation information determined by a Global Positioning System (GPS) unit of the user system 102.
Another type of filter is a data filter, which may be selectively presented to a sending user by the interaction client 104 based on other inputs or information gathered by the user system 102 during the message creation process. Examples of data filters include current temperature at a specific location, a current speed at which a sending user is traveling, battery life for a user system 102, or the current time.
Other augmentation data that may be stored within the image table 316 includes augmented reality content items (e.g., corresponding to applying “lenses” or augmented reality experiences). An augmented reality content item may be a real-time special effect and sound that may be added to an image or a video.
A story table 318 stores data regarding collections of messages and associated image, video, or audio data, which are compiled into a collection (e.g., a story or a gallery). The creation of a particular collection may be initiated by a particular user (e.g., each user for which a record is maintained in the entity table 308). A user may create a “personal story” in the form of a collection of content that has been created and sent/broadcast by that user. To this end, the user interface of the interaction client 104 may include an icon that is user-selectable to enable a sending user to add specific content to his or her personal story.
A collection may also constitute a “live story,” which is a collection of content from multiple users that is created manually, automatically, or using a combination of manual and automatic techniques. For example, a “live story” may constitute a curated stream of user-submitted content from various locations and events. Users whose client devices have location services enabled and are at a common location event at a particular time may, for example, be presented with an option, via a user interface of the interaction client 104, to contribute content to a particular live story. The live story may be identified to the user by the interaction client 104, based on his or her location. The end result is a “live story” told from a community perspective.
A further type of content collection is known as a “location story,” which enables a user whose user system 102 is located within a specific geographic location (e.g., on a college or university campus) to contribute to a particular collection. In some examples, a contribution to a location story may employ a second degree of authentication to verify that the end-user belongs to a specific organization or other entity (e.g., is a student on the university campus).
As mentioned above, the video table 314 stores video data that, in some examples, is associated with messages for which records are maintained within the message table 306. Similarly, the image table 316 stores image data associated with messages for which message data is stored in the entity table 308. The entity table 308 may associate various augmentations from the augmentation table 312 with various images and videos stored in the image table 316 and the video table 314.
The databases 304 also includes temperature (temp) and power data table 318. The temperature and power data table 318 includes, referring to
The contents (e.g., values) of the various components of message 400 may be pointers to locations in tables within which content data values are stored. For example, an image value in the message image payload 406 may be a pointer to (or address of) a location within an image table 316.

Each of the temple pieces 846 and 847 can include a first portion 851 that is coupled to the respective end portion 841 or 842 of the front piece 833 and any suitable second portion 852, such as a curved or arcuate piece, for coupling to the ear of the user. In one example, the front piece 833 can be formed from a single piece of material, so as to have a unitary or integral construction. In one example, the entire frame 832 can be formed from a single piece of material so as to have a unitary or integral construction.
The glasses 800 include a computing device, such as a computer 861, which can be of any suitable type so as to be carried by the frame 832 and, in one example, of a suitable size and shape, so as to be at least partially disposed in one or more of the temple pieces 846 and 847. In one example, the computer 861 has a size and shape similar to the size and shape of one of the temple pieces 846, 847 and is thus disposed almost entirely if not entirely within the structure and confines of such temple pieces 846 and 847.
In one example, the computer 861 can be disposed in both of the temple pieces 846, 847. The computer 861 can include one or more processors with memory, wireless communication circuitry, and a power source. The computer 861 comprises low-power circuitry, high-speed circuitry, location circuitry, and a display processor. Various other examples may include these elements in different configurations or integrated together in different ways. Additional details of aspects of the computer 861 may be implemented as described with reference to the description that follows.
The computer 861 additionally includes a battery 862 or other suitable portable power supply. In one example, the battery 862 is disposed in one of the temple pieces 846 or 847. In the glasses 800 shown in
The glasses 800 include digital cameras 869. Although two cameras 869 are depicted, other examples contemplate the use of a single or additional (i.e., more than two) cameras 869. For ease of description, various features relating to the cameras 869 will be described further with reference to only a single camera 869, but it will be appreciated that these features can apply, in suitable examples, to both cameras 869.
In various examples, the glasses 800 may include any number of input sensors or peripheral devices in addition to the cameras 869. The front piece 833 is provided with an outward-facing, forward-facing, front, or outer surface 866 that faces forward or away from the user when the glasses 800 are mounted on the face of the user, and an opposite inward-facing, rearward-facing, rear, or inner surface 867 that faces the face of the user when the glasses 800 are mounted on the face of the user. Such sensors can include inward-facing video sensors or digital imaging modules such as cameras 869 that can be mounted on or provided within the inner surface 867 of the front piece 833 or elsewhere on the frame 832 so as to be facing the user, and outward-facing video sensors or digital imaging modules such as the cameras 869 that can be mounted on or provided with the outer surface 866 of the front piece 833 or elsewhere on the frame 832 so as to be facing away from the user. Such sensors, peripheral devices, or peripherals can additionally include biometric sensors, location sensors, accelerometers, or any other such sensors. In some examples, projectors (not illustrated) are used to project images on the inner surface of the optical elements 843, 844 (or lenses) to provide a mixed reality or augmented reality experience for the user of the glasses 800.
The glasses 800 further include an example of a camera control mechanism or user input mechanism comprising a camera control button mounted on the frame 832 for haptic or manual engagement by the user. The camera control button provides a bi-modal or single-action mechanism in that it is disposable by the user between only two conditions, namely an engaged condition and a disengaged condition. In this example, the camera control button is a push button that is by default in the disengaged condition, being depressible by the user to dispose it to the engaged condition. Upon release of the depressed camera control button, it automatically returns to the disengaged condition.
In other examples, the single-action input mechanism can instead be provided by, for example, a touch-sensitive button comprising a capacitive sensor mounted on the frame 832 adjacent to its surface for detecting the presence of a user's finger, to dispose the touch-sensitive button to the engaged condition when the user touches a finger to the corresponding spot on the outer surface 866 of the frame 832. It will be appreciated that the above-described camera control button and capacitive touch button are but two examples of a haptic input mechanism for single-action control of the camera 869, and that other examples may employ different single-action haptic control arrangements.

For example, a resource 1002 may be a graphics processing unit (GPU) that at state 1008 with a clock speed of 1,000 MHz consumes 37 milli-Watts (mW) per percent of utilization 1006 of the GPU resource 1002. The operating system 942 can determine based on a time that the process 1019 uses the GPU resource 1002 and a utilization 1006 of the GPU, the energy used 1024 in mW-seconds or joules (J) used by the process 1019 for the GPU resource 1025. The process 1019 is an application 928, 944 being executed or run. The process 1019 is process 929 and/or process 940. The operating system 942 runs on the SOCs 926, 938 and the process 1019 may be run on one or more of the SOCs 926, 938.
The temperature generation 1010 is an indication of an increase in temperature based on the utilization 1012 and state 1013 of the resource 1002. For example, continuing with the example above. If the GPU resource 1002 is in a 1,000 MHz state 1008, then the temperature generation 1010 is 0.01 degrees F. per 1 percent utilization 1012 per second of use. The temperature generation 1010 enables the operating system 942 to attribute a change in the current temperature 1014 of a resource 1002 because of the use of the resource 1002 by a process 1019. In some examples, the temperature generation 1010 is non-linear and depends on total power consumption 1004 and/or on utilization of the resource 1002. The kernel module 1030 may approximate the temperature generation 1010 based on the total power consumption 1004 and/or resource utilization.
Software or hardware 1016 indicates whether the resource 1002 is software or hardware. For example, a process 1019 may be an end user application 928, 944 such as identifying objects for the user or playing a video for the user. When the process 1019 directly executes and uses a GPU resource 1002, then the GPU resource 1002 is hardware. And when the process 1019 uses an application 928, 944 such as an application 928, 944 to identify hand gestures, then this is software. The application 928, 944 from which the process 1019 originated may provide services for other applications 928, 944.
The operating system 942 executes or runs the applications 928, 944, which becomes a process 1019 in execution or in being run. The operating system 942 may use an interpreter to run the applications 928, 944, in which case the process 1019 being tracked may be the interpreter and the application 928, 944 is attributed with power consumption 1004 and temperature generation 1010 based on the use of the interpreter resource 1002. For example, the operating system 942 attributes the power consumption 1004 and temperature generation 1010 to an application 928, 944 using the interpreter resource 1002, which is a process 1019 when being used, based on the power consumption 1004 and temperature generation 1010 of the interpreter resource 1002 when the interpreter resource 1002 is running the application 928, 944. The current temperature 1014 is an indication of the temperature of the resource 1002, which may be determined based on a temperature sensor 906, 914, 920, 930, 936.
When the resource 1002 is a software process, the operating system 942 may use previously determined estimates for power consumption 1004 and temperature generation 1010 for running the software resource 1002. For example, for a hand gesture recognition resource 1002, the operating system 942 may access information that indicates a power consumption 1004 and temperature generation 1010 for the hand gesture recognition resource 1002 based on an amount of time the hand gesture recognition resource 1002 is active and, in some examples, further based on state 1008 of the other resources 1002 such as the GPU or CPU resource 1002.
The operating system 942 monitors processes 1019 for energy used 1024 per resource 1025 and temperature used 1028. The energy budget 1022 indicates an amount of energy the process 1019 is budgeted to use. The energy budget 1022 may per resource 1002. The temperature budget 1026 indicates a change in temperature that the process 1019 is budgeted. The temperature budget 1026 may be per resource 1002.
The kernel module 1030 is configured to perform operations that require the kernel of the operating system 942 to perform. For example, the kernel module 1030 provides services to stop processes 1019 and to log a time a process 1019 is started and stopped.
The budget module 1032 determines an energy budget 1022 and temperature budget 1026 for a process 1019. In some examples, the energy budget 1022 and temperature budget 1026 are predetermined and associated with the application 928, 944. In some examples, the energy budget 1022 and temperature budget 1026 are determined based on current temperatures 1014 of the resources and/or the charge of the battery 918 based on the charge sensor 910. The budget module 1032 sends to the process 1019 updates on the energy used 1024 and the temperature used 1028 so that the process 1019. The budget module 1032 sends to the process 1019 when the process 1019 is completed a total energy used 1024 and a total temperature used 1028. The budget module 1032 determines the power consumption 1004 and temperature generation 1010 to use for a resource 1002 based on the utilization 1006, 1012, and state 1008, 1013.
The throttle module 1018 performs action when a process 1019 exceeds its energy budget 1022 or temperature budget 1026. For example, when a process 1019 exceeds its energy budget 1022 or exceeds its temperature budget 1026, the throttle module 1018 calls the throttle module 1020 that is part of the process 1019. The throttle module 1020 of the process 1019 may terminate the process 1019, reduce the energy used 1024 and/or temperature used 1028, or perform another action. The throttle module 1018 may perform another action such analyzing the energy used 1024 and temperature used 1028 and placing a resource 1002 that is being used by the process 1019 into a state 1008 that uses less power consumption 1004 and/or temperature generation 1010. For example, in the GPU resource 1002 example, the throttle module 1018 may reduce a number of cores of the GPU resource 1002 that are turned on, change the 1,000 MHz state 1008 to a 500 MHz state 1008, or reduce the availability of one or more cores of the GPU resource 1002 to the process 1019.
In some examples, throttle module 1020 reduces the features of the application 928, 944. For example, the throttle module 1020 may disable hand tracking. The throttle module 1018 may reduce or lower a priority of the process 1019 so that it is executed or run less frequently. In some examples, the throttle module 1018 may throttle the use of a resource 1002. For example, if a current temperature 1014 of the resource 1002 exceeds or transgresses a threshold, the throttle module 1018 may reduce access to the resource 1002.
In some examples, the throttle module 1018 will lower a priority of processes 1019 that are using the resource 1002. In some examples, the throttle module 1018 will suspend processes 1019 that request to use the resource 1002. In some examples, the throttle module 1018 will indicate to the process 1019 that using a resource 1002 may result in the process 1019 being suspended or the throttle module 1018 may indicate to the process 1019 that the resource 1002 is currently unavailable due to its current temperature 1014. The throttle module 1018 may provide a time period when the resource 1002 may become available. In some examples, the throttle module 1018 will switch the resource 1002 for another resource 1002 that may perform the operation. For example, if a GPU resource 1002 has a current temperature 1014 that exceeds or transgress a threshold temperature, then the throttle module 1018 substitutes another GPU resource 1002, a CPU resource 1002, or sends the operation to be performed by another device.
In some examples, the throttle module 1018 may suspend the process 1019 or reduce a priority of the process 1019. In some examples, the throttle module 1018 may remove a resource 1002 from the process 1019. For example, if the wireless module 904 is becoming too hot, then the throttle module 1018 may suspend the use of the wireless module 904 by the process 1019 for a period of time. In some examples, the throttle module 1018 or throttle module 1020 will, in response, to the amount of energy used 1024 or the temperature used 1028, indicate to the process 1019 to offload computationally intensive functions to another device via the wireless module 904. For example, the head-wearable apparatus 116 will offload image processing for hand tracking to a computing device 114 such as a user system 102 that may be mobile phone.
In other examples, the throttle module 1018 calls a throttle module 1020 of the process 1019. The throttle module 1020 of the process 1019 may determine its own actions to reduce the power consumption 1004 and temperature generation 1010. For example, the process 1019 may reduce the features available for an end-user application 928, 944. The process 1019 is an application 928, 944 that is being executed. In some examples, the process 1019 reduces the features being offered by not providing hand tracking. In some examples, the throttle module 1020 will throttle the process 1019 if
In block 1108, HW and SW resource utilization is determined for unit tests. And in block 1102 the HW subsystem power measurements are determined for the unit tests based on the utilization. For example, individual resources 1002 of the system 900 are measured for power consumption 1004 based on the utilization 1006 and state 1008 of the resource 1002. Example resources 1002 include the processors 932, 940, such as GPUs and CPUs, the display 912, the wireless module 904, the inter-SOC communication bus 934, and applications 928 such as 3D graphics, compositing, video recording, VIO, hand tracking, and depth from stereo images. When a resource 1002 is SW such as hand tracking, then the power measurements are used for each of the HW subsystems that are used by the SW. The temperature generation 1010 for a resource 1002 is determined in a similar or same way.
In block 1110, HW and SW resource utilization is determined for end-to-end tests. And in block 1104 the HW subsystem power measurements for estimating power consumption 1004 are determined for the end-to-end tests based on the utilization. The end-to-end tests run the entire SW application 928, 944, and the unit tests run portions of the SW such as only the hand tracking or only a communication portion. In the end-to-end HW tests, for example, both the GPU and CPU may be running while in the unit test only the GPU or CPU may be tested. In the end-to-end SW tests the entire SW application 928, 944 is executed. The temperature generation 1010 for a resource 1002 is determined in a similar or same way.
The relationship 1106 is determined based on running the empirical tests and determining the relationship between the power usage and the resource utilization. The relationship 1114 is then adjusted to generate the adjusted relationship 1114 based on electronic/electrical engineering (EE) power models. For example, equations of the power usage of the GPU and CPU are provided describing the power usage of the product. The relationship 1106 may be adjusted to fit or be less deviant from theoretical EE power models 1112.
In some examples, the CPUs and/or GPUs are heterogeneous architectures with different portions that may be used separately. The different portions may consume different amounts of power. The utilization in these examples may be determined for each portion.
The interpreter process 1019 has a utilization of the CPU of 60%, a utilization of the GPU A of 30%, a utilization of the GPU B of 25%, and a utilization of the inter-SOC communication bus 934 of 5%.
Using Table 1 and Table 2 an estimate for the power consumption 1004 of the interpreter process 1019 can be made. Table 1 is for a minute of execution by the interpreter process 1019, so the numbers in Table 2 are multiplied by 60. Using the mean power consumption is used from Table 2, the power consumed by the interpreter process 1019 is (for CPU) 9.4*60*0.6+ (for GPU A) 8.2*60*0.3+ (For GPU B) 8.5*60*0.25+ (for inter-SOC communication bus) 0.1*60*0.05, which equals 338.4+147.6+127.5+0.3, or 613.8 mW for the 60 seconds the interpreter process 1019 was executing.
The method 1200 continues at operation 1206 with tracking per process utilization for HW blocks. For example, as discussed in conjunction with Tables 1 and 2, the utilization of each resource 1002 is tracked for a process 1019 by the operating system 942. The method 1200 continues at operation 1208 with determining per process power usage and temperature generation. For example, as disclosed in conjunction with Tables 1 and 2, for each resource 1002 the power consumption 1004 and temperature generation 1010 is determined based on the utilization 1006, 1012, and state 1008, 1013 by the operating system 942.
The method 1200 may optionally include one or more additional operations. The operations of method 1200 may be performed in a different order. One or more of the operations of method 1200 may be optional.
The method 1400 continues at operation 1406 with estimating an energy usage used by the resource for the application, the estimating based on a resource utilization and a resource usage duration. For example, the operating system 942 maintains information regarding the use of the resource 1002 by the process 1019 such as the energy used 1024 for the resource 1025. The operating system 942 uses predetermined estimates for the power consumption 1004 of the resource 1002 based on the utilization 1006 by the process 1019. The kernel module 1030 may keep track of which process 1019 is using which resource 1002 to determine the utilization 1006.
The method 1400 continues at operation 1408 with throttling the power usage of the application. In response to the power usage transgressing a power usage budget for the application. For example, the throttle module 1018 may call the throttle module 1020 of the process 1019 for the process 1019 to reduce its energy used 1024. In another example, the throttle module 1018 changes the state 1008 of the resource 1002 to a state 1008 that reduces the power consumption 1004 of the resource 1002.
The method 1400 may optionally include one or more additional operations. The operations of method 1400 may be performed in a different order. One or more of the operations of method 1400 may be optional. The method 1400 may be performed in whole or in part by an apparatus of the head-wearable apparatus 116, the glasses 800, the server system 504, the computing device 114, and so forth.
Examples enable a mobile device such as head-wearable apparatus 116 to attribute power consumption 1004 and temperature generation 1010 used by processes 1019 on a per resource 1002 bases. The processes 1019, which may be end-user applications 928, 944, receive information regarding energy used 1024 and temperature used 1028 on a per resource 1025, 1029 bases. This enables the applications 928, 944 to better use their energy budget 1022 and temperature budget 1026. Additionally, the mobile device may throttle a process 1019 that exceeds an energy budget 1022 or temperature budget 1026.
Circuitry or circuits, as used in this document, may comprise, for example, singly or in any combination, hardwired circuitry, programmable circuitry such as computer processors comprising one or more individual instruction processing cores, state machine circuitry, and/or firmware that stores instructions executed by programmable circuitry. The circuits, circuitry, or modules may, collectively or individually, be embodied as circuitry that forms part of a larger system, for example, an integrated circuit (IC), system on-chip (SoC), desktop computers, laptop computers, tablet computers, servers, smart phones, etc.
As used in any embodiment herein, the term “logic” may refer to firmware and/or circuitry configured to perform any of the aforementioned operations. Firmware may be embodied as code, instructions or instruction sets and/or data that are hard-coded (e.g., nonvolatile) in memory devices and/or circuitry.
“Circuitry,” as used in any embodiment herein, may comprise, for example, singly or in any combination, hardwired circuitry, programmable circuitry, state machine circuitry, logic and/or firmware that stores instructions executed by programmable circuitry. The circuitry may be embodied as an integrated circuit, such as an integrated circuit chip. In some embodiments, the circuitry may be formed, at least in part, by the processor circuitry executing code and/or instructions sets (e.g., software, firmware, etc.) corresponding to the functionality described herein, thus transforming a general-purpose processor into a specific-purpose processing environment to perform one or more of the operations described herein. In some embodiments, the processor circuitry may be embodied as a stand-alone integrated circuit or may be incorporated as one of several components on an integrated circuit. In some embodiments, the various components and circuitry of the node or other systems may be combined in a system-on-a-chip (SoC) architecture.
“Carrier signal” refers, for example, to any intangible medium that is capable of storing, encoding, or carrying instructions for execution by the machine and includes digital or analog communications signals or other intangible media to facilitate communication of such instructions. Instructions may be transmitted or received over a network using a transmission medium via a network interface device.
“Client device” refers, for example, to any machine that interfaces to a communications network to obtain resources from one or more server systems or other client devices. A client device may be, but is not limited to, a mobile phone, desktop computer, laptop, portable digital assistants (PDAs), smartphones, tablets, ultrabooks, netbooks, laptops, multi-processor systems, microprocessor-based or programmable consumer electronics, game consoles, set-top boxes, or any other communication device that a user may use to access a network.
“Communication network” refers, for example, to one or more portions of a network that may be an ad hoc network, an intranet, an extranet, a virtual private network (VPN), a local area network (LAN), a wireless LAN (WLAN), a wide area network (WAN), a wireless WAN (WWAN), a metropolitan area network (MAN), the Internet, a portion of the Internet, a portion of the Public Switched Telephone Network (PSTN), a plain old telephone service (POTS) network, a cellular telephone network, a wireless network, a Wi-Fi® network, another type of network, or a combination of two or more such networks. For example, a network or a portion of a network may include a wireless or cellular network, and the coupling may be a Code Division Multiple Access (CDMA) connection, a Global System for Mobile communications (GSM) connection, or other types of cellular or wireless coupling. In this example, the coupling may implement any of a variety of types of data transfer technology, such as Single Carrier Radio Transmission Technology (1×RTT), Evolution-Data Optimized (EVDO) technology, General Packet Radio Service (GPRS) technology, Enhanced Data rates for GSM Evolution (EDGE) technology, third Generation Partnership Project (3GPP) including 3G, fourth-generation wireless (4G) networks, Universal Mobile Telecommunications System (UMTS), High Speed Packet Access (HSPA), Worldwide Interoperability for Microwave Access (WiMAX), Long Term Evolution (LTE) standard, others defined by various standard-setting organizations, other long-range protocols, or other data transfer technology.
“Component” refers, for example, to a device, physical entity, or logic having boundaries defined by function or subroutine calls, branch points, APIs, or other technologies that provide for the partitioning or modularization of particular processing or control functions. Components may be combined via their interfaces with other components to carry out a machine process. A component may be a packaged functional hardware unit designed for use with other components and a part of a program that usually performs a particular function of related functions. Components may constitute either software components (e.g., code embodied on a machine-readable medium) or hardware components. A “hardware component” is a tangible unit capable of performing certain operations and may be configured or arranged in a certain physical manner. In various examples, one or more computer systems (e.g., a standalone computer system, a client computer system, or a server computer system) or one or more hardware components of a computer system (e.g., a processor or a group of processors) may be configured by software (e.g., an application or application portion) as a hardware component that operates to perform certain operations as described herein. A hardware component may also be implemented mechanically, electronically, or any suitable combination thereof. For example, a hardware component may include dedicated circuitry or logic that is permanently configured to perform certain operations. A hardware component may be a special-purpose processor, such as a field-programmable gate array (FPGA) or an application-specific integrated circuit (ASIC). A hardware component may also include programmable logic or circuitry that is temporarily configured by software to perform certain operations. For example, a hardware component may include software executed by a general-purpose processor or other programmable processors. Once configured by such software, hardware components become specific machines (or specific components of a machine) uniquely tailored to perform the configured functions and are no longer general-purpose processors. It will be appreciated that the decision to implement a hardware component mechanically, in dedicated and permanently configured circuitry, or in temporarily configured circuitry (e.g., configured by software), may be driven by cost and time considerations. Accordingly, the phrase “hardware component” (or “hardware-implemented component”) should be understood to encompass a tangible entity, be that an entity that is physically constructed, permanently configured (e.g., hardwired), or temporarily configured (e.g., programmed) to operate in a certain manner or to perform certain operations described herein. Considering examples in which hardware components are temporarily configured (e.g., programmed), each of the hardware components need not be configured or instantiated at any one instance in time. For example, where a hardware component comprises a general-purpose processor configured by software to become a special-purpose processor, the general-purpose processor may be configured as respectively different special-purpose processors (e.g., comprising different hardware components) at different times. Software accordingly configures a particular processor or processors, for example, to constitute a particular hardware component at one instance of time and to constitute a different hardware component at a different instance of time. Hardware components can provide information to, and receive information from, other hardware components. Accordingly, the described hardware components may be regarded as being communicatively coupled. Where multiple hardware components exist contemporaneously, communications may be achieved through signal transmission (e.g., over appropriate circuits and buses) between or among two or more of the hardware components. In examples in which multiple hardware components are configured or instantiated at different times, communications between such hardware components may be achieved, for example, through the storage and retrieval of information in memory structures to which the multiple hardware components have access. For example, one hardware component may perform an operation and store the output of that operation in a memory device to which it is communicatively coupled. A further hardware component may then, at a later time, access the memory device to retrieve and process the stored output. Hardware components may also initiate communications with input or output devices, and can operate on a resource (e.g., a collection of information). The various operations of example methods described herein may be performed, at least partially, by one or more processors that are temporarily configured (e.g., by software) or permanently configured to perform the relevant operations. Whether temporarily or permanently configured, such processors may constitute processor-implemented components that operate to perform one or more operations or functions described herein. As used herein, “processor-implemented component” refers to a hardware component implemented using one or more processors. Similarly, the methods described herein may be at least partially processor-implemented, with a particular processor or processors being an example of hardware. For example, at least some of the operations of a method may be performed by one or more processors or processor-implemented components. Moreover, the one or more processors may also operate to support performance of the relevant operations in a “cloud computing” environment or as a “software as a service” (SaaS). For example, at least some of the operations may be performed by a group of computers (as examples of machines including processors), with these operations being accessible via a network (e.g., the Internet) and via one or more appropriate interfaces (e.g., an API). The performance of certain of the operations may be distributed among the processors, not only residing within a single machine, but deployed across a number of machines. In some examples, the processors or processor-implemented components may be located in a single geographic location (e.g., within a home environment, an office environment, or a server farm). In other examples, the processors or processor-implemented components may be distributed across a number of geographic locations.
“Computer-readable storage medium” refers, for example, to both machine-storage media and transmission media. Thus, the terms include both storage devices/media and carrier waves/modulated data signals. The terms “machine-readable medium,” “computer-readable medium” and “device-readable medium” mean the same thing and may be used interchangeably in this disclosure.
“Ephemeral message” refers, for example, to a message that is accessible for a time-limited duration. An ephemeral message may be a text, an image, a video and the like. The access time for the ephemeral message may be set by the message sender. Alternatively, the access time may be a default setting or a setting specified by the recipient. Regardless of the setting technique, the message is transitory.

The term “signal medium” shall be taken to include any form of a modulated data signal, carrier wave, and so forth. The term “modulated data signal” means a signal that has one or more of its characteristics set or changed in such a matter as to encode information in the signal. The terms “transmission medium” and “signal medium” mean the same thing and may be used interchangeably in this disclosure.
