Low-latency consumption of an encoded video bitstream
Systems, apparatuses, and methods for reducing latency when consuming an encoded video bitstream in real-time are disclosed. A video encoder encodes a video bitstream and writes chunks of the encoded bitstream to a bitstream buffer. Prior to the encoder completing the encoding of an entire frame, or an entire slice of a frame, a consumer module consumes encoded chunks of the bitstream. In one implementation, to enable pipelining of the consumption with the encoding, the encoder updates a buffer write pointer with an indication of the amount of data that has been written to the bitstream buffer. The consumer module retrieves encoded data from the bitstream buffer up to the location indicated by the buffer write pointer. In this way, the consumer module is able to access and consume encoded video data prior to the encoder finishing encoding an entire frame or an entire slice of the frame. |

Image data processing
A method of configuring an image encoder emulator. Input image data is encoded at an encoding stage comprising a network of inter-connected weights, and decoded at a decoding stage to generate a first distorted version of the input image data. The first distorted version is compared with a second distorted version of the input image data generated using an external encoder to determine a distortion difference score. A rate prediction model is used to predict an encoding bitrate associated with encoding the input image data to a quality corresponding to the first distorted version. A rate difference score is determined by comparing the predicted encoding bitrate with an encoding bitrate used by the external encoder to encode the input image data to a quality corresponding to the second distorted version. The weights of the encoding stage are trained based on the distortion difference score and the rate difference score. |

Methods and apparatus for true high dynamic range imaging
When imaging bright objects, a conventional detector array can saturate, making it difficult to produce an image with a dynamic range that equals the scene's dynamic range. Conversely, a digital focal plane array (DFPA) with one or more m-bit counters can produce an image whose dynamic range is greater than the native dynamic range. In one example, the DFPA acquires a first image over a relatively brief integration period at a relatively low gain setting. The DFPA then acquires a second image over longer integration period and/or a higher gain setting. During this second integration period, counters may roll over, possibly several times, to capture a residue modulus 2m of the number of counts (as opposed to the actual number of counts). A processor in or coupled to the DFPA generates a high-dynamic range image based on the first image and the residues modulus 2m. |

Resource management techniques for dialog-driven applications
A resource of a dialog-driven management service is allocated for a first set of requests based on determining that a population of capacity indicators in a throttling data structure exceeds a threshold.

Generating and linking private transaction identifiers to distributed data repositories
Techniques are described for generating semi-random private transaction identifiers for users that are meaningful to data providers and can be used by data providers to perform internal queries for user data. A user provides input to an identity management service indicating the user's consent to link their user account at the identity management service to one or more data providers.

A shutoff valve, a first gas pressure sensor, a pressure reducing valve, a second gas pressure sensor, and a gas supply component are provided, sequentially from a gas tank side, in a gas supply flow channel that extends from the gas tank to a gas consuming component. Besides, a buffer tank is provided, via an on-off valve, in a branch flow channel that branches off from the gas supply flow channel between the pressure reducing valve and the gas supply component. This buffer tank is in a situation where the pressure of the buffer tank is not higher than a consumption prescribed gas pressure. In calibrating the first gas pressure sensor, with the shutoff valve closed and with the on-off valve open, a detection value of the first gas pressure sensor is calibrated through the use of a detection value of the second gas pressure sensor. |

Methods and apparatus for controlling electrodeposition using surface charge properties
Surface conduction in porous media can drastically alter the stability and morphology of electrodeposition at high rates, above the diffusion-limited current. Above the limiting current, surface conduction inhibits growth in the positive membrane and produces irregular dendrites, while it enhances growth and suppresses dendrites behind a deionization shock in the negative membrane. The discovery of uniform growth contradicts quasi-steady “leaky membrane” models, which are in the same universality class as unstable Laplacian growth, and indicates the importance of transient electro-diffusion or electro-osmotic dispersion. Shock electrodeposition could be exploited for high-rate recharging of metal batteries or manufacturing of metal matrix composite coatings. |
