Abstract: Systems and techniques for permitting, establishing, monitoring and controlling calls based on messages from outside parties, outside party availability information, institution's call restriction information, and/or account holder preferences. In one example, a message from an outside party app on an outside party computing device is receive by an inmate app on an inmate device. The inmate device displays the message at the inmate calling app including a request for the inmate to call the outside party device during a time period. When the inmate initiates a call to the outside party the call is permitted or not permitted based on determining whether the call is within the specified time period.

Abstract: A method for video encoding includes determining that a current block in a first coding tree unit (CTU) of a current picture is to be coded using an affine model in a merge mode, and obtaining, from a line buffer, one or more motion vectors of blocks located at bottom locations in a second CTU above the current block. The line buffer only stores motion vectors of minimum-size blocks located at the bottom locations of the second CTU above the current block and the line buffer does not store (i) a block width or block height of the minimum-size blocks, (ii) affine control point information, and (iii) an affine flag. The method further includes deriving motion vectors of control points of the current block using the affine merge model, and encoding the current block based on the affine merge model and the motion vectors of the control points.

Abstract: A light detection and ranging (LIDAR) system can emit light toward an environment and detect responsively reflected light to determine a distance to one or more points in the environment. The reflected light can be detected by a plurality of plurality of photodiodes that are reverse-biased using a high voltage. Signals from the plurality of reverse-biased photodiodes can be amplified by respective transistors and applied to an analog-to-digital converter (ADC). The signal from a particular photodiode can be applied to the ADC by biasing a respective transistor corresponding to the particular photodiode while not biasing transistors corresponding to other photodiodes. The gain of each photodiode/transistor pair can be controlled by adjusting the bias voltage applied to each photodiode using a digital-to-analog converter. The gain of each photodiode/transistor pair can be controlled based on the detected temperature of each photodiode.

Abstract: Methods, apparatus, systems, and computer-readable media are provided for tailoring composite graphical assistant interfaces for interacting with multiple different connected devices. The composite graphical assistant interfaces can be generated in response to a user providing a request for an automated assistant to cause a connected device to perform a particular function. In response to the automated assistant receiving the request, the automated assistant can identify other connected devices, and other functions capable of being performed by the other connected devices. The other functions can then be mapped to various graphical control elements in order to provide a composite graphical assistant interface from which the user can interact with different connected devices. Each graphical control element can be arranged to reflect how each connected device is operating simultaneous to the presentation of the composite graphical assistant interface.

Abstract: A system includes a gas turbine (GT) system at a power plant operatively coupled to a generator to always generate power at a baseload. A first portion of the GT system's baseload power is transmitted to an electric grid. Where demand for power from the grid does not exceed a threshold, a second portion of the GT system's baseload power is transmitted to a hydrogen-producing electrolyzer to generate hydrogen fuel for a second GT system. Where demand for power from the grid exceeds the threshold, a third portion of the GT system's baseload power is transmitted to the grid. The GT system always runs at baseload but is capable of providing increased power to the grid quickly, like conventional spinning reserves. The system improves efficiencies by running all GT systems at baseload, and reduces emissions for the second GT system by providing hydrogen fuel thereto when grid power demand allows.

Abstract: Techniques of providing continual augmented reality navigation include combining first and second 6DoF poses from, respectively, a localization from a map in a vicinity of a location to an image and from predicted 6DoF poses based on IMU data. The first 6DoF pose is based on a visual positioning system that uses map data from a vicinity of a location combined with an image from the world-facing camera of the AR smartglasses that provides 6DoF pose in world coordinates independent of the IMU. The second 6DoF pose is based on compensated rotational velocity and acceleration measurements derived from IMU intrinsic values.

Abstract: Implementations relate to determining a language for speech recognition of a spoken utterance, received via an automated assistant interface, for interacting with an automated assistant. Implementations can enable multilingual interaction with the automated assistant, without necessitating a user explicitly designate a language to be utilized for each interaction. Selection of a speech recognition model for a particular language can based on one or more interaction characteristics exhibited during a dialog session between a user and an automated assistant. Such interaction characteristics can include anticipated user input types, anticipated user input durations, a duration for monitoring for a user response, and/or an actual duration of a provided user response.
