Abstract: A system-on-chip (SoC) having a switchable power domain capable of being placed in a standby mode during which a power supply of the switchable power domain is gated and having an always-on power domain. The always-on power domain includes an input sampling circuit, and the switchable power domain includes an input/output (IO) circuit configured to, during normal operation, receive data at a corresponding signal pin when an input buffer of the IO circuit is enabled, in which the corresponding signal pin is coupled to the input sampling circuit. The input sampling circuit is configured to, while the switchable power domain is entering the standby mode but before the power supply is gated, provide an override input enable signal to enable the input buffer of the IO circuit, sample an input bit value on the corresponding signal pin, and store the sampled bit value to provide an injection current fault indicator.

Abstract: When a first search query including an image of an item is received to search for items associated with similar images, a second search query that includes text based on the image is generated. The text may be based on previous queries associated with the depicted item, visual features of the image, or text that is present in the image. The results from the first search query are scored based on their correspondence with the image of the item. Results having a score greater than a threshold are presented first in the output, followed by a selected number of results from the second search query. Results from the first search query that are associated with a score less than the threshold may be presented after the results from the second search query. This presentation increases the likelihood that items presented earlier in the output are relevant to the initial query.

Abstract: Techniques are disclosed relating to authorizing varying levels of access to computer resources. In one embodiment, consider an authorization server, a resource server that includes a resource (for example, a data item), and an application server operable to incorporate the resource into its own functionality. The authorization server may receive information indicative of a grant of access privileges by a user, authorizing the application server to access the resource. The authorization server may be configured to provide the application server with varying levels of access to the resources of the resource server. For example, the authorization server may provision a plurality of access tokens corresponding to the grant of access privileges to the application server. The plurality of access tokens may each be associated with a scope of access and a duration. In various embodiments, the duration of an access token may be based on its corresponding scope of access.
