Further, the systems and methods can determine whether access to the cacheable resource should be provided via the content distribution network or a proxy server based at least partially on a relative location of the proxy server and the content distribution network to the user system requesting access to the network page.

Abstract: Robots or other machines may be used for retrieving errant objects from the floor of an automated warehouse. A system can include one or more reporting methods to alert a central control to the existence and location of an object on the warehouse floor. The central control can establish a safety zone around the object to avoid contact with normal warehouse traffic (e.g., standard warehouse robots). The system can route a cleanup robot to the location to retrieve the object. The system can include a cleanup pod comprising a convertible shelving unit with a robotic arm. The cleanup pod can have a similar form factor as shelving units used for storing inventory in the warehouse, thereby enabling standard warehouse robots to lift and transport the cleanup pod to retrieve an object.

Abstract: A streaming source sends streaming content to a display device. A camera captures images of the display device playing the streaming content and/or a user's interaction with the display device along with the displayed response to the user's interaction. The captured content is analyzed to determine, for example, image quality characteristics of the displayed content, a user experience associated with the displayed content or whether the displayed content matches an expected outcome associated with testing input. Information determined from the analysis of the captured content may be used to adjust characteristics of the streaming content, such as streaming parameters at the streaming source or configuration of the display device. A testing system may analyze the captured content to evaluate performance of the streaming system. Results of the testing may be sent to a data store and/or used to mitigate a poor user experience such as poor image quality.

Abstract: The amount of resources needed to provide automatic exposure control (AEC) for a camera of a computing device, as well as the amount of latency required to determine an appropriate exposure setting for current conditions, can be improved utilizing an ambient light sensor (ALS) that is integrated with a camera module corresponding to the camera. The ALS can capture data regarding the amount of ambient light around the device, and a microprocessor or other component of the camera module can analyze the data using an AEC algorithm or other such process to determine one or more initial exposure settings for the camera. This process can be completed without sending image data to a host processor or other such component. Providing relatively accurate initial exposure settings can, in at least many situations, enable the AEC algorithm to more quickly converge to proper settings than is possible using conventional approaches.

Abstract: The state of firmware for devices on a provisioned host machine can be validated independent of the host CPU(s) or other components exposed to the user.

The firmware can be scanned and a hashing or similar algorithm can be used to determine validation information, such as hash values, for the firmware, which can be compared to validation information stored in a secure location. If the current and stored validation information do not match, one or more remedial actions can be taken to address the firmware being in an unknown or unintended state.

Correspondingly, the second state may be a second power state of the device in which the device and the display are powered on and content is being rendered on the display. If the decision engine cannot make a determination based on the sensor data, a context engine may adjudicate the user presence determination.

The identified keywords can be stored and/or transmitted to an appropriate location accessible to entities such as advertisers or content providers who can use the keywords to attempt to select or customize content that is likely relevant to the user.

Abstract: Described are techniques and systems for determining presence of airborne particles using one or more sensors on a user device. The airborne particles include, but are not limited to, smoke resulting from combustion, dust, fog, and so forth. In one implementation, an optical proximity sensor may be used to determine a distance to an object such as a ceiling. Smoke which collects on the ceiling reflects light that is detected by the proximity sensor and results in an apparent reduction in height. A notification of this change in height may be generated. In other implementations, other techniques may be used to detect airborne particles, such as images from a camera, dedicated particular sensors, and so forth. Information about airborne particles may aid user safety. For example, an alarm may be issued indicating a potential fire or unsafe level of pollution.
