A drop characteristic may then be determined from the drop detector for each ink-jet nozzle. Drop characteristics for the nozzles across the printhead may be collated into a data set, and compared with a predetermined data set for a printhead having predetermined print behaviour to determine if and how the data sets differ in terms of the pattern of drop characteristics across the printheads. If the data sets differ, a recovery strategy may be selected based how the data sets differ in terms of the pattern of drop characteristics across the printheads. A system and computer readable medium are also described herein.

    Abstract: In the examples provided herein, an apparatus has modules to be cooled during operation, where each module is coupled to a heatsink, and the heatsinks are coupled to a first surface of a thermally conductive plate. The modules are positioned along a direction from a first side of the plate toward an opposite side of the plate. The apparatus also has heat pipes coupled to a second surface of the plate to transport heat away from the modules during operation, where the heat pipes are positioned nonuniformly along the direction.

  • Publication number: 20180227372
    Abstract: An example method, for implementation by an example notification system, comprises creating a TCP connection between a client device and a cloud device; sending, by the cloud device, a first UDP message to the client device; and waiting, by the client device, to receive the first UDP message until a predetermined time after the creation of the TCP connection. If the client device has not received the first UDP message by the predetermined time, the method comprises sending, by the client device, a second UDP message to the cloud device, wherein sending the second UDP message starts an open time period during which the client device is able to receive UDP messages from the cloud device.

    Abstract: Example implementations relate to detecting document objects. For example, detecting document objects may include a system comprising a pre-processing engine to establish a threshold for a document, wherein a structure of the document is unknown, a detection engine to detect a candidate area in the document, using a Hough transform and connected component analysis to merge detected candidate areas in the Hough transform to a same document object in the document, and a classification module to classify the candidate area as a document object or not a document object.
