    Abstract: The present disclosure relates to a touch display device including a substrate, a pixel area in which at least one subpixel is disposed, a first touch sensor area located on a first side of the pixel area, a second touch sensor area located on a second opposing side of the pixel area, at least one pixel electrode disposed in the pixel area, a first electrode disposed in the first touch sensor area, and a second electrode disposed in the second touch sensor area. As the first electrode and the second electrode include a metal included in the at least one pixel electrode, the touch display device can provide an effect of reducing the thickness of a display panel even though a touch sensor is embedded in the display panel.

    Abstract: An agent computer system uses a session-less login process to log in two users in a same application session. The system establishes an application session with an application server and a user session with the application server by authenticating a first user using an identity provider system (IdP). The system detects a request to perform an action by the first user within the application session that requires a second user's authentication. While maintaining the user session, the system requests a session-less authentication of the second user by transmitting an authentication request, which includes a flag indicating that the requested authentication is a session-less authentication. The system receives a confirmation of the authentication of the second user without establishing a second user session and performs the requested action in response to receiving the confirmation of the authentication of the second user.

    Abstract: An item recognition system uses a top camera and one or more peripheral cameras to identify items. The item recognition system may use image embeddings generated based on images captured by the cameras to generate a concatenated embedding that describes an item depicted in the image. The item recognition system may compare the concatenated embedding to reference embeddings to identify the item. Furthermore, the item recognition system may detect when items are overlapping in an image. For example, the item recognition system may apply an overlap detection model to a top image and a pixel-wise mask for the top image to detect whether an item is overlapping with another in the top image. The item recognition system notifies a user of the overlap if detected.

    Abstract: A system receives a service request sent from a computing device of a user, which identifies a service to be provided. The system then identifies potential locations based on the service request and historical data. These locations are assessed based on predetermined criteria, including an amount of successful and unsuccessful service requests at each location according to the historical data. After a location is chosen, the user's acceptance is obtained. Upon receiving this acceptance, the system generates and sends navigation instructions from the provider's current position to the selected location to a second computing device associated with the provider.

    Abstract: Disclosed herein is a method, system, or non-transitory computer readable medium for evaluating a query on a columnar dataset comprising one or more dictionaries associated with columns in the dataset. The method includes receiving a request to perform a query comprising at least an operator for a columnar dataset on cloud storage. At least one column in the dataset is based on a dictionary, and the dictionary maps one or more values for a column to one or more respective identifiers. The method evaluates the operator on one or more values of the dictionary to generate an updated dictionary comprising updated values. The method may decode the updated dictionary into an updated column comprising updated data values.

    Abstract: A cluster computing system maintains a first set of queues for short queries and a set second set for longer queries. The first set is allocated a majority of the cluster's processing resources and processes queries on a first in first out basis. The second set is allocated a minority of the cluster's processing resources which are shared among queries in the second set. Accordingly, the system assigns each query to the first set of queues for a fixed amount of resource time. While a query is processing, the system monitors the query's resource time and reassigns the query to the second set of queues if the query has not completed within the allotted amount of resource time. Thus, short queries receive the necessary resources to complete quickly without getting stuck behind longer queries while ensuring that longer queries continue to make progress.
