Techniques for controlling cooling of electronic components in computing facilities are disclosed herein. In one embodiment, a method includes detecting a pressure drop of a coolant flowing across multiple servers in an enclosure between the inlet and outlet manifolds and a supply temperature of the coolant at the inlet manifold. The method further includes automatically adjust operations of the pump to maintain the calculated pressure drop at or near a pressure-drop setpoint while automatically adjusting operations of the air mover to maintain the supply temperature at or near a temperature setpoint.

Control systems for air-assisted and liquid-cooled enclosures

The description relates to cooling electronic components, such as computing devices. One example includes a rack defining a volume and multiple sealed chassis modules removably fluidly coupled to a two-phase condenser tank via a vapor coupler and a liquid coupler. Individual sealed chassis modules can contain one or more electronic components immersed in two-phase coolant that when heated by operation of the electronic components experiences a phase change from a liquid phase to a gas phase and travels to the two-phase condenser tank via the vapor coupler and is cooled in the two-phase condenser tank until experiencing a phase change back into the liquid phase. Individual sealed chassis modules can be decoupled from the two-phase condenser tank without releasing two-phase coolant and an entirety of the multiple sealed chassis modules and the condenser tank are contained in the volume of the rack.

Computer cooling

A method is disclosed. In the method, color differences are calculated between a current video frame and a motion predicted version of the current video frame based on a human visual system's ability to perceive the color differences. Also, information in a difference frame is discarded based on the color differences. The difference frame includes differences between the current video frame and the motion predicted version of the current video frame.

Techniques for video compression

The discussion relates to disaggregated computing. One example can monitor multiple two-phase liquid immersion tanks. Individual two-phase liquid immersion tanks can contain multiple components of a single type of component type. The example can receive requests for virtual machines and allocate sets of components from individual two-phase liquid immersion tanks to work together to support the virtual machines requests.

Disaggregated computer systems

In one example, a printer with adaptive sampling includes a print engine, a monochrome scanner, a light source, and an analysis module. The light source has independently controlled primaries oriented to illuminate a media from the print engine. The analysis module includes a page selection module to select a chosen page of media for analysis, a heuristic analysis module to analyze the chosen page and determine a region of the page for analysis, a light control module to select a mono-color for the light source in region on the chosen page, and a quality module to accept an image of the chosen page and a scan of the chosen page with the monochrome scanner illuminated by the selected mono-color and compare the image and the scan within the region to determine a discrepancy.

Adaptive sampling

Examples described herein relate to a system consistent with the disclosure. For instance, the system may comprise a printing device including hardware to form markings on a print medium, a memory resource, and a controller to receive a print job to form the markings on the print medium, render a page description language of the print job to form the markings, determine an object type image of the print job, designate pixels of the determined object type image to form a covert dot pattern on the image, and adjust colors of the designated pixels to form the covert dot pattern on the markings.

Covert dot patterns

Examples described herein relate to a system consistent with the disclosure. For instance, the system may comprise a printing device including hardware to form an image on a print medium, a memory resource, and a controller to receive a print job to form the markings on the print medium, designate a pixel of the received print job to form a covert dot pattern on the markings, where the pixel corresponds to a first laser intensity level; and adjust a laser intensity of the printing device to a second laser intensity level based on the first laser intensity level of the designated pixel to form the covert dot pattern.

Covert marking

A server system comprising storage devices, processing devices and a storage fabric all operating according to a storage fabric protocol. The storage fabric comprises a plurality of individual switches having a modular design from which an overall switch is built, and the individual switches have individual respective configuration settings which determine which processing devices are allocated to use which of the storage devices. The system comprises an API enabling a software control function to configure the overall switch. The API is operable to receive from the control function an overall mapping of the storage devices to the processing devices instead of requiring the individual configuration settings of each of the individual switches to be specified by the control function, the API being configured to convert the overall mapping into the individual configuration settings of the individual switches to produce the overall mapping.

Server system

Strips of a page are processed according to a rendering technique, compressed, and stored in a memory buffer until a low memory condition of the buffer occurs. When the low memory condition occurs, the strips that are already stored in the buffer are decompressed, processed according to a memory utilization reduction technique, compressed, and stored in the memory buffer. Strips that are not yet already stored in the buffer when the low memory condition occurs are processed according to the rendering technique and then according to the memory utilization reduction technique before being compressed and stored in the memory buffer.

Reprocessing of page strips responsive to low memory condition

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.

Detecting document objects

Pixel blocks of a user-generated print job raster page are clustered into raster color clusters, and pixel blocks of a corresponding scanned page are clustered into scanned color clusters. For each raster color cluster, if a color difference between the cluster and a corresponding scanned color cluster is greater than a threshold, color fading of the cluster is determined from simulated depletion of each colorant of a printing device, and a likely depleted colorant is determined based on the corresponding scanned color cluster and the determined color fading. A most likely depleted colorant is determined from the likely depleted colorant predicted for each raster color cluster for which the determined color difference is greater than the threshold.

Predicting depleted printing device colorant from color fading

A memory controller that performs address replacement using combinational logic. A dedicated buffer receives a target address corresponding to a memory operation instruction. Another dedicated buffer holds a problem address. Yet another dedicated buffer holds a repair address to be used to replace the problem address when memory operations instructions are targeted at that problem address. An address compare combinational circuit compares a received target address held by the dedicated target address buffer with a problem address held by the dedicated repair address buffer. If there is a match, the address compare combinational circuit generates a match notification signal. In response to a match notification signal, an address circuit, which may also be a combinational circuit, responds by causing the repair address within the dedicated repair address buffer to be targeted by the memory operation instruction instead of the problem address being targeted.

Combinational address repair in memory controller

The present application includes devices and methods for using corrective data for a reconstructed table. In some examples, a computing device can generate a key from a reconstructed table, determine corrective data for the reconstructed table based on the generated key, and implement the corrective data to the reconstructed table to generate an updated table.
