Abstract: A non-transitory computer-readable storage medium stores executable instructions that, when executed by a processor, cause performance of operations comprising operations to access an image captured by an image sensor, obtain a transfer function for mapping pixel values, determine a faces indication that reflects a proportion of a scene depicted in the image that includes one or more human faces, and modify the transfer function based on the faces indication. Modifying the transfer function based on the faces indication comprises adjusting a gain of the transfer function to move the gain closer to unity. The operations include to apply the transfer function to pixel values of the image to produce a tone mapped image and output the tone mapped image.

Abstract: Process for continuous manufacture of an unlimited length latex foam block including at least two layers to form after successive cross cuts resting articles such as mattresses, cushions and parts of such articles. At least a first and second latex foam mixture with different characteristics among them are separately prepared and sent consecutively at a predetermined distance from each other on a laying surface in continuous progress. The second mixture is deposited on the already shaped first layer. The first and the second layers are gelatinized concurrently at the same place. The two layers are directly joined to each other along the contact surface by mechanical co-penetration of appendices of the one into micro-cavities of the other and by reciprocal tack of the two layers latex particles following breaking of the protective barrier between particles during gelatinizing.

Abstract: A voltage converter comprises two input terminals between which at least a current limiter, an electronic switch controlled by a control device in synchronization with the supply voltage and a storage capacitor are disposed, and whose two output terminals are taken from the storage capacitor, wherein the current limiter is formed by at least the primary of a transformer whose secondary supplies a rectifier whose output terminals are connected to the output terminals of the converter.
