Examples of the present disclosure relate to a container. The container has a chamber for storing build material for a three-dimensional printing system. The container comprises an opening coaxial with the chamber for coupling to the three-dimensional printing system. The container is configured such that rotation of the chamber in a first direction conveys build material in the chamber to the three-dimensional printing system and rotation of the chamber in a second direction conveys the build material away from the three-dimensional printing system.

Chamber for storing build material

According to one aspect, there is provided a method of adding build material to a rotatable 3D printing build material container having an internal build material storage reservoir, the method comprising: providing a supply of build material to an input port of the container; rotating the container about its rotation axis at a first speed sufficient to cause build material within the container to be centrifugally forced against the outside of the internal storage reservoir.

Adding build material to a build material container

Ink supplies are disclosed in examples herein. An example apparatus a housing includes a first chamber and a second chamber, the housing defining a first port to fluidly couple the first chamber to a printer, the housing including a second port to fluidly couple the first chamber and the second chamber to flow fluid from the second chamber to the first chamber. The apparatus also includes a regulator coupled between the first chamber and the second chamber, the regulator to flow gas from the first chamber to the second chamber when a pressure within the first chamber reaches a threshold.

Ink supplies

In one example, a container for holding printing fluid includes a chamber to hold a printing fluid and an inelastic, expandable, and contractible bag occupying space in the chamber. The exterior of the bag is exposed to an interior of the chamber and an interior of the bag is sealed against the interior of the chamber and vented to the atmosphere.

Printing fluid container

Systems, devices, and methods for configurable sensor arrays are provided. An example of a configurable sensor array includes a plurality of sensors in a matrix array formed on a single backplane and a plurality of elements within one of the plurality of sensors, where the plurality of elements provides alternative electrical paths enabling the one of the plurality of sensors to have a range of output impedances.

Configurable sensor arrays

Embodiments disclosed herein relate to a filter (). In one embodiment, the filter includes a pattern (). The pattern may reflect or fluoresce non-visible light.

Filter

A display element includes a first electrode including conductive lines, a second electrode, and a dielectric layer on the first electrode. The dielectric layer has recess regions therein exposing at least portions of the conductive lines. The display element includes a fluid with colorant particles between the first electrode and the second electrode.

Display element including electrodes and a fluid with colorant particles

An electro-optical display includes colorant particles that are suspended in a carrier fluid. The colorant particles are controlled by three different types of electrodes. An exposed electrode acts on the colorant particles in an electrokinetic manner by compacting the colorant particles. A passivated electrode acts on the colorant particles in an electrostatic manner by holding the colorant particles once compacted. A reference electrode attracts the colorant particles to compaction areas.

Electro-optical display

An electronic device comprises a substrate and an electrical contact in contact with the dielectric layer and electrically coupled with at least one resistor, a substrate carrier including an electrical trace electrically coupled to the electrical contact, a polymer enclosing the electrical contact, and a substantially planar film disposed over the electrical contact.

Electrical contact encapsulation

Embodiments of the present invention provide a flexible circuit at least partially encapsulated by a cover layer. The flexible circuit includes a substrate having one or more openings. One or more electrical conductors are bonded to the top surface of the substrate. A first cover layer is bonded to the top surface of the substrate and to the electrical conductors. A second cover layer is bonded to the bottom surface of the substrate and to the first cover layer through the openings.
