Abstract: A method and corresponding system for reconstructing the surface geometry of a three-dimensional object is disclosed. The system comprises a cluster of heterogeneous sensors, including a two-dimensional high-resolution camera and a three-dimensional depth camera, and a turntable operable to rotate incrementally. In operation, the turntable is rotated to first and second positions and two-dimensional and three-dimensional data sets are obtained using the two-dimensional high-resolution camera and the three-dimensional depth camera. Corresponding features from the two-dimensional data sets are identified and used to identify the same corresponding features in the three-dimensional data sets. The three-dimensional corresponding features are used to calculate a three-dimensional homography, which is used to align the three-dimensional data sets. Following alignment, a three-dimensional mesh is generated from the aligned data sets.

Abstract: Examples relate to a turntable peripheral for three dimensional (3D) scanning. In some examples, 3D scan data of a real-world object is obtained while the object is rotated by the turntable peripheral. Positioning commands are sent to the turntable peripheral to rotate the object. The 3D scan data is collected while the turntable peripheral is in an untilted and/or tilted position.

Abstract: A system includes a calibration plate with fiducial markers, a device under test interface, an alignment stage with a rotary sub-stage and a linear sub-stage, and a camera on the alignment stage.

Abstract: An example device, for sealing an ink developer unit in accordance with aspects of the present disclosure includes a rigid plate. The device also includes a first compliant sealing member disposed on a first side of the rigid plate to form a seal between the number of rollers of the ink developer unit and the rigid plate. The device also includes a second compliant sealing member disposed on a second side of the rigid plate to form a seal between the rigid plate and an end cap of the ink developer unit. The first compliant sealing member, the second compliant sealing member, or combinations thereof include a developer roller arm aligned with an interior portion of a developer roller face and to allow ink to contact the developer roller face.

Abstract: Apparatus and methods are provided. A supply of ink within a flexible bag is located apart from a printer. A fluid conduit couples the supply of ink to the printer by way of a connecting head. The connecting head includes a pump driven by a mechanical actuator of the printer. Operation of the pump causes a flow of ink from the flexible bag to a printhead of the printer. Pump failure is detected and interpreted as an out-of-ink condition, and user notification and/or cessation of printing operations are automatically performed.

Abstract: A liquid electrophotographic ink developer comprises a developer roller (112) rotatable about an axis, first and second electrodes (108, 110) proximate the developer roller (112) and an inlet chamber (100) extending along the axis from a first end adjacent an inlet opening (122) to a second end opposite the first end. A neck (104) forms an uninterrupted ink flow path from the inlet chamber (100) to the developer roller (112).

Abstract: A liquid electrophotographic ink developer comprises a developer roller (112) rotatable about an axis, first and second electrodes (108, 110) proximate the developer roller (112) and an inlet chamber (100) extending along the axis from a first end adjacent an inlet opening (122) to a second end opposite the first end. A neck (104) forms an uninterrupted ink flow path from the inlet chamber (100) to the developer roller (112).

Abstract: In one example, a processor readable medium has instructions thereon that, when executed by a processor, cause a system to detect a change in electrical conduction of a liquid moving at an interface between two surfaces and determine a conductivity of the liquid based on the detected change in conduction.

Abstract: A sealing device usable with an ink developer unit including a plurality of rollers and a plurality of end cap members includes a first replaceable compliant sealing member and a latch member. The first replaceable compliant sealing member has a plurality of replaceable seal exterior surfaces to form a seal between a first set of rollers of the plurality of rollers and one of the end cap members. The latch member has a closed state to maintain a sealing force on the first replaceable compliant sealing member and an open state to remove the sealing force on the first replaceable complaint sealing member.

Abstract: An apparatus to receive a developer roller for a printing device. The apparatus comprises a base assembly including end caps at opposing ends. The base assembly includes a receptacle for a developer roller having rotary bearings. Each end cap includes first and second datum pins and a clamp containing a spring member. Each clamp, when locked in place in part by action of the spring member, is to push against a corresponding rotary bearing when the developer roller is installed in the base assembly. The rotary bearing being forced by the clamp into contact with the first and second datum pins to position the developer roller in the base assembly.
