Abstract: Examples disclosed herein relate to combining region based image classifiers. In one implementation, a processor measures correct classification and misclassification levels associated with a first image classifier related to a first image feature region and measures correct classification and misclassification levels associated with a second image classifier related to a second image feature region. The processor may create a combined classifier based on the first image classifier correct classification and misclassification levels and based on the second image classifier correct classification and misclassification levels such that the combined classifier is related to the first image feature region and the second image feature region.

Abstract: An example system includes an object and a support frame supporting the object. The support frame constrains movement of the object relative to the support frame, and the support frame includes at least one of a cage or a shackle to non-rigidly constrain movement of at least a part of the object.

Abstract: In an example of a 3D printing method, build material particles are applied to form a layer. Each build material particle includes a metal core and a metal oxide outer shell. The layer is patterned by selectively applying a reactive chemical on at least a portion of the layer to initiate a redox reaction with the metal oxide outer shells of the build material particles in contact with the reactive chemical, which reduces the metal oxide outer shells of the build material particles in contact with the reactive chemical and exposes the metal cores of the build material particles in contact with the reactive chemical. The patterned layer is exposed to rapid thermal processing to sinter the exposed metal cores to form a part layer. Any intact build material particles remain unsintered.

Abstract: A surface enhanced Raman spectroscopy (SERS) sensor may include a nano structured surface and a nonstoichiometric oxide layer. The nano structured surfers may include a first peak, a second peak and a valley between the first peak and the second peak. The non-stoichiometric oxide layer may include a first portion on the first peak and a second portion on the second peak.

Abstract: An example device includes at least one three-dimensional (3D) printed tablet and a 3D-printed production support structure. Each 3D-printed tablet includes an excipient material and an active ingredient. The 3D-printed support structure includes a 3D-printed planar structure comprising the excipient material and at least one 3D-printed connecting member comprising the excipient material. The planar structure includes at least one aperture, each aperture corresponding to one of the at least one 3D-printed tablet. The connecting member detachably connects the at least one 3D-printed tablet with the 3D-printed planar structure and positions the at least one 3D-printed tablets within the apertures.

Abstract: According to an example, an apparatus may include a printhead to deliver a printing liquid from firing chambers through a plurality of bores arranged along a surface of the printhead. The apparatus may also include a cleaning system to apply a pressurized cleaning fluid onto the surface of the printhead while preventing application of the pressurized cleaning fluid into the firing chambers through the plurality of bores.

Abstract: A method for providing workflows includes capturing an image of an information-carrying component of a workflow object. The method also includes determining a language of the workflow object based on the captured image. The method additionally includes determining that the language of the workflow object is different from a language context of the device. Further, the method includes generating a workflow based on the information-carrying component, the language of the workflow object, and the language context. The workflow generates additional information for the information-carrying component.

Abstract: Examples associated with printer encryption are described. One example printer includes a data store to store a one-time pad. An encryption module may encrypt a message using the one-time pad. The encryption module also transmits the encrypted message to a trusted device that stores a copy of the one-time pad. A decryption module uses the one-time pad to decrypt a received message form the trusted device. The decryption module also controls the printer to perform an action based on the received message. A refresh module replaces the one-time pad during a service event.

Abstract: A method for authenticating an instance of an object comprises transmitting an object-instance identity derived from identity data associated with an instance of the object to an object service, receiving location data from the object service representing locations of respective ones of multiple object-instance-specific virtual marks, and transmitting data derived from one or more of the virtual marks to the object service.
