Abstract: An output compensation circuit of an image sensor includes a first current mirror circuit, a first current generator circuit and a second current generator circuit. The first current mirror circuit, coupled to a select transistor of a pixel circuit of the image sensor, is configured to, in response to a first current, generate a second current flowing through the select transistor. The select transistor is selectively turned on according to a power supply voltage. When the select transistor is turned on, the pixel circuit outputs the second current through the select transistor. The first current generator circuit outputs a compensation current, serving as a first portion of the first current, to the first current mirror circuit in response to a variation in the power supply voltage. The second current generator circuit outputs a reference current, serving as a second portion of the first current, to the first current mirror circuit.

Abstract: A bullet comment processing method and apparatus, a server, and a storage medium are provided. When a bullet comment needs to be released, at least one candidate track matching a to-be-released bullet comment format is identified; then, a display duration of an existing bullet comment content in each candidate track is determined as a first duration corresponding to the each candidate track, and a display duration of a to-be-released bullet comment content when being placed in the each candidate track is determined as a second duration corresponding to the each candidate track; the second duration and the first duration of the each candidate track are compared, and a target track is identified to display the to-be-released bullet comment, where the second duration of the target track is greater than the first duration; and the to-be-released bullet comment content is displayed at the target track.

Abstract: A wireless network optimizing node receives key performance indicators (KPIs) from a base station of a cell site providing wireless service within a geographic area, wherein the KPIs are associated with wireless communication between beams of an antenna array of the cell site and User Equipment. The node determines a current cell site capacity usage for the cell site based on current wireless network usage parameters received from the cell site and determines a need for an additional antenna array to provide adequate coverage and capacity for the geographic area based on the current cell site capacity usage and the first KPIs. The node determines an optimum location within the geographic area for adding the additional antenna array.

Abstract: Network conditions are taken into consideration, by wireless edge devices, when streaming content, such as video content, over a wireless network. A video capture device, such as a video recorder, may be controlled, by the edge device, to adjust the bit rate, capture resolution, or other parameters relating to upload bandwidth of the video stream. The wireless edge device may transcode the video stream received from the capture device to adjust the encoding technique for the video stream. Advantageously, the wireless network and edge devices may work together to offer optimal video quality that fits within required network constraints.

Abstract: An exemplary virtual reality system presents virtual reality media content including representations of a plurality of objects to a user. The system detects a characteristic of a real-world environment of the user as the virtual reality media content is presented to the user and identifies, based on the detected characteristic of the real-world environment, an actionable real-world object included in the real-world environment. In response to the identifying of the actionable real-world object and as the virtual reality media content is presented to the user, the system dynamically integrates a proxy object corresponding to the actionable real-world object with the representations of the plurality of objects included within the virtual reality media content presented to the user. The proxy object may be configured to facilitate an action by the user with respect to the actionable real-world object as the virtual reality media content is being presented.

Abstract: A mobile device includes a wireless transceiver, a host processor, a secure element (SE), and a near field communication (NFC) system having an NFC transceiver and an NFC controller implementing a contactless front end. The contactless front end routes a near field communication related to a payment transaction between the NFC system and the SE without going to or from the host processor. The contactless front end routes a near field communication not related to a payment transaction, but requiring a security function, between the NFC system and the SE without going to or from the host processor. The contactless front end routes a near field communication not related to a payment transaction, and not requiring a security function, between the NFC system and host processor without going to or from the SE.

Abstract: Examples are disclosed that facilitate provisioning of a toll system communication device used in an electronic toll collection system, such as EZ Pass. The toll system communication device (e.g., an EZ Pass tag) can have user credentials provided to it that are associated with a user payment account. As a user travels a toll road, the toll system communication device is interrogated at a toll booth location. In response to the interrogation, the toll system communication device provides information identifying the toll system communication device and associated user credentials. The user credentials may be obtained from or authenticated with a mobile device within close proximity to the vehicle equipped with the toll system communication device. Using the user credentials and the identifying information, a user payment account may be provisioned to pay tolls accrued by the vehicle using the toll road.

Abstract: To virtually transfer subscriber identity module (“SIM”) credentials from an active device to an inactive device in order to share carrier network access, temporary identifiers and SIM credentials are transferred using secure connections and an optional public-private key pair with encryption at the transport layer. In an example, a carrier identification (“ID”) server receives a temporary identifier, such as a temporary international mobile subscriber identity (“TIMSI”), from an inactive device via a carrier network. The carrier ID server authenticates the inactive device using the TIMSI by issuing a network challenge. Next, the carrier ID server verifies with an active device associated with the inactive device that the active device distributed the TIMSI. After authenticating and verifying with both devices, the carrier ID server activates the inactive device by allowing the TIMSI to behave as virtual SIM credentials on the carrier network.

Abstract: Examples are provided that enable a cellular network location assist to confirm a position determined using a sensor of a mobile device. As a result of global positioning system signals becoming unavailable due to the mobile device traveling indoors, the mobile device implements a sensor-based position determination that provides a position of the mobile device as the mobile device travels about a location. In order to confirm the reliability of the sensor-based position determination, the mobile device, after passage of time or after traveling some estimated distance, requests location assistance indications from the cellular network. A processor of the mobile device receives the location assistance indications and generates a directional vector based on several of the location assistance indications. Using the directional vector, the processor confirms the reliability of the dead reckoning position.
