Abstract: The present invention relates to a method for compressing light-fields by exploiting their overall 4D redundancy using a hybrid approach that combines the benefits of sparse coding approach with pseudo-video sequence or multi-view coding to explore the inter-SAI redundancy and achieves very competitive results. This redundancy is particularly high when the light-fields are densely sampled. Therefore, this invention is especially efficient for densely sampled light-fields, such as the ones acquired by light-field cameras.

Abstract: Certain examples relate to a build material management system to transport build material from a collection to source to one of a plurality of storage tanks. The storage tank is determined by a controller that compares color of the build material measured by a color sensor with predetermined values. The controller routes the build material to the storage tank.

Abstract: Certain examples relate to a storage tank loading system for loading powdered build material to a storage tank and generating a quality indicator. In these examples, the quality indicator may be generated by comparing a measured color with at least one predetermined threshold value, in these examples, the color of powdered build material is determined by a color sensor.

Abstract: A printer comprising an electrical load, a control system and an electrical circuit to switchably connect the electrical load to a first phase and a second phase of a polyphase power supply. The control system monitors a first electrical current drawn by the printer on the first phase and a second electrical current drawn by the printer on the second phase. When a difference between the first electrical current and the second electrical current satisfies a threshold condition, the control system controls the electrical circuit to disconnect the electrical load from the first phase and connect the electrical load to the second phase.

Abstract: An example of an apparatus is disclosed. The apparatus comprises a controller to obtain a desired quality level for an object to be printed based on an input. The controller is also to determine a ratio of a first build material and a second build material based on the desired quality level. The first build material is a higher quality build material than the second build material. The controller is further to prepare a mix of build material of the determined ratio to be used during generation of the object.

Abstract: A printer comprising an electrical load, a control system and an electrical circuit to switchably connect the electrical load to a first phase and a second phase of a polyphase power supply. The control system monitors a first electrical current drawn by the printer on the first phase and a second electrical current drawn by the printer on the second phase. When a difference between the first electrical current and the second electrical current satisfies a threshold condition, the control system controls the electrical circuit to disconnect the electrical load from the first phase and connect the electrical load to the second phase.
