Abstract: A graphics processing system for performing tile-based rendering of a scene that comprises safety-related primitives. The system comprises a plurality of graphics processing units (GPUs), each configured to i) receive tile data identifying one or more protected tiles comprising at least part of a safety-related primitive, ii) process two respective sets of protected tiles, and iii) based on said processing, generate two respective checksums for each respective set of protected tiles. The two respective sets of protected tiles are mutually exclusive, and each respective set and each protected tile being processed by two different GPUs. The system comprises a comparison unit configured to compare one or more pairs of checksums, each pair comprising a respective checksum generated based on a same respective set of protected tiles and generated by different GPUs. The graphics processing system is configured to perform one or more actions based on an outcome of said comparison.

Abstract: Adder circuits and associated methods for processing a set of at least three floating-point numbers to be added together include identifying, from among the at least three numbers, at least two numbers that have the same sign—that is, at least two numbers that are both positive or both negative. The identified at least two numbers are added together using one or more same-sign floating-point adders. A same-sign floating-point adder comprises circuitry configured to add together floating-point numbers having the same sign and does not include circuitry configured to add together numbers having different signs.

Abstract: An air amplifier for directing airflow from a fan assembly, and a fan assembly including an air amplifier. The air amplifier includes an inlet for receiving airflow from a fan assembly, and an airflow cavity. The airflow cavity includes a first wall and a second wall that define an airflow passageway extending towards an exhaust outlet for emitting air. A divider body is provided within the passageway. The divider body divides the airflow passageway into a first exhaust passageway and a second exhaust passageway. The divider body tapers towards the exhaust outlet.

Abstract: Methods and intersection testing modules are provided for determining, in a ray tracing system, whether a ray intersects a 3D axis-aligned box representing a volume defined by a front-facing plane and a back-facing plane for each dimension. The front-facing plane of the box which intersects the ray furthest along the ray is identified. It is determined whether the ray intersects the identified front-facing plane at a position that is no further along the ray than positions at which the ray intersects the back-facing planes in a subset of the dimensions, and this determination is used to determine whether the ray intersects the axis-aligned box. The subset of dimensions comprises the two dimensions for which the front-facing plane was not identified, but does not comprise the dimension for which the front-facing plane was identified.

In one aspect, a system includes a language encoder model that is configured to receive a text string in a particular natural language, and process the text string to generate a text embedding of the text string. The system includes an observation encoder neural network that is configured to receive an observation characterizing a state of the environment, and process the observation to generate an observation embedding of the observation. The system includes a subsystem that is configured to obtain a current text embedding of a current text string and a current observation embedding of a current observation. The subsystem is configured to select an action to be performed by the agent in response to the current observation.

Abstract: The present invention discloses methods and systems for reducing network latency. A first network device establishes a plurality of connections with a second network device. After that, determining non-congesting latency of each of the plurality of connections. Assigning a weighting to each of the plurality of connections. Decreasing the weighting of a connection when the performance of the connection deteriorated according to a first criteria. The first network device may perform weight decreasing again after a time interval. Last, sending data packets through the plurality of connections according to the weightings.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for generating images using neural networks. One of the methods includes generating the output image pixel by pixel from a sequence of pixels taken from the output image, comprising, for each pixel in the output image, generating a respective score distribution over a discrete set of possible color values for each of the plurality of color channels.

Abstract: A spray fan includes a box, a mounting base and a fan body. The fan body can be arranged on the mounting base. The opposite sides of the mounting base can be respectively fastened with the box so that the fan body has a first state arranged on the box and a second state contained in the box. The fan body can be set on the box when in use. The fan body can be inverted and stored in the box when storing to improve the convenience of storage.

Abstract: A three-dimensional structure sensing system includes an image sensor that receives a reflected light from an object irradiated by an emitted light, the reflected light being converted into image data representing an image of the object; and a depth processing unit that generates depth data according to the image data. It is determined whether the depth data is affected by a reflective surface according to the image data and the depth data.

Abstract: An anode including a current collector and an anode active material layer disposed on the current collector are provided. The anode active material layer includes first oriented particles having a first tilt angle ?1 inclined with respect to the direction parallel to the current collector, and second oriented particles having a second tilt angle ?2 inclined with respect to the direction parallel to the current collector. The first tilt angle ?1 and the second tilt angle ?2 are different and both not greater than 70°.
