Reducing smear and slow response artifacts in vector error diffusion
A method of color image processing for quantizing output includes obtaining an input for an object pixel which is represented by a vector in a first color space. A modified input equal to the input plus a sum of errors from other pixels in a neighborhood of the object pixel is generated. For each color component in the first color space, where corresponding color components of the modified input are located with respect to a preset range is determined. If the modified input's color component is greater than the preset range, then that color component for an output is determined to be on; if less than the preset range, then that color component for the output is determine to be off; and, if within the preset range, then that color component for the output is determined to be unknown. A transformed modified input is mapped to a perceptual color space when any color component of the output is unknown. Colors consistent with color components of the output that have already been determined are also mapped to the perceptual color space. The color in the perceptual color space that lies closest to the transformed modified input is chosen. An output in the first color space having color components on and off is generated consistent with the determinations and/or choices made. Error for the object pixel is then calculated as the difference between the output and the modified input. |

Adaptive multi-service data framing
When a signal-to-noise ratio affecting radio communication becomes sufficiently low, then the data transmission rate is responsively decreased in compensation. The signal-to-noise ratio of the communication link is thereby increased. Data for multiple different services is transmitted in data packets between two radios. By allocating one part, or time slot, of the data packet's payload to one service, and allocating another part, or time slot, of the data packet's payload to another service, communications sessions for multiple services can be maintained concurrently. Services are prioritized relative to each other. In case the signal-to-noise ratio becomes too low, data packet portions that are related to lower-priority services can be omitted from some data packets before those data packets are transmitted. Data remaining in the packet can be sent at a reduced data transmission rate without causing the quality of service for the remaining packets to fall below the minimum required level. |

Cell cooling frames with cantilevered side seals
A modular battery pack and method of making a battery pack. Prismatic can battery cells are interspersed with cooling frames along a stacking axis within a housing such that numerous a cell-frame assemblies, each with a cooling path, are formed. Resiliently-biased sealing members on the frames are arranged such that they remain out of the way of a footprint defined by the joined cells and frames to promote ease of high-speed cell-to-frame assembly.

By this sealing member construction, cell-frame assemblies may be produced with high-speed automated assembly techniques that may have both large manufacturing tolerances prior to assembly and substantially gap-free cell-to-cooling frame contacting surfaces after assembly. |
