Server-based video stitching
Approaches, techniques, and mechanisms are disclosed for the server-based stitching of a sequence of video segments. According to one embodiment, rather than combining the segments together into a single video file, a server (e.g. a segment-based HTTP server) is configured to dynamically switch between streaming the different segments in the sequence.

Transcoder
A transcoder that controls the amount of generated codes of an output stream toward a target bit rate without degradation of image quality. The transcoder decodes a first stream and encodes the decoded image again to thereby output a second stream. The transcoder calculates a distortion evaluation value from the image obtained by decoding the first stream and an image obtained by decoding the second stream. Assuming that a ratio between the distortion evaluation value and a total target distortion evaluation value is determined as a target distortion ratio, a target setting bit rate of a second stream in the period can be obtained by multiplying a total target bit rate of the second stream by the target distortion ratio. Alternatively, the target setting bit rate can be obtained by adjusting the target distortion ratio with an appropriate function and adding the target distortion ratio to the total target bit rate of the second stream. |

Generating comparator thresholds using a rotating ring of resistors
Data converters convert signals in analog form to digital form or from digital form to analog form. Due to mismatches between devices that are intended to be identical (unary elements), some data converters outputs may have undesirable characteristics, such as non-linearities.

A method and a system are provided for controlling an air intake of a fuel cell vehicle. The method includes calculating a value for basic air intake of a fuel cell based on a driver requirement and calculating a value of motor current requirement based on the driver requirement. A rate-of-change is calculated of the value of motor current requirement and a value for supplementary air intake is calculated by multiplying the rate-of-change of the value of motor current requirement by a gain value. A value for final air intake is then calculated by adding the value for basic air intake and the value for supplementary air intake. An air blower of an air intake system of the fuel cell is operated with the value for final air intake. |

Fuel cell system and method of operating fuel cell system
The invention is provided to reliably restore generated voltage that has declined due to clogging of water in a fuel cell stack. A method of operating a fuel cell system having a fuel cell stack that generates electricity through an electrochemical reaction between a fuel gas including hydrogen gas and an oxidation gas, wherein when a generated voltage of the fuel cell stack declines, the water-in-cell content of the fuel cell stack is adjusted so that a variation in cell pressure loss in the fuel cell stack decreases based on a characteristic curve of the water-in-cell content of the fuel cell stack and the cell pressure loss of the fuel cell stack. |
