  • Publication number: 20180012900
    Abstract: The present subject matter relates to an integrated circuit comprising an erasable programmable read only memory (EPROM) array having a plurality of EPROM cells disposed in rows and columns, wherein one or more EPROM cells located at predetermined positions in the EPROM array are selectively dischargeable. The one or more EPROM cells comprise a EPROM transistor having a first conductive layer to store electrons upon the EPROM transistor being programmed and a control metal oxide semiconductor field-effect transistor (MOSFET) electrically connected to the first conductive layer to provide an electron leakage path to dissipate the electrons stored in the first conductive layer in a predetermined leak time period.

  • Publication number: 20180011806
    Abstract: A computing system for supporting a plurality of different types of memory devices includes a memory voltage regulator. The memory voltage regulator adjusts a supply voltage to a requisite voltage for a detected memory device based on serial presence detect (SPD) data. The computing system further includes a memory controller that supports a plurality of types of memory devices. The memory controller receives data regarding the type of the detected memory device, and controls input/output signals relative to the type of the detected memory device based on the SPD data and the GPIO data of the detected memory device.

  • Publication number: 20180011476
    Abstract: Certain examples described herein relate to structure forming for the production of a three-dimensional object. In these examples, different structure forming components or functions are applied to volumes of a three-dimensional object. These structure forming components or functions are arranged to differentially generate a halftone output. The halftone output is generated by processing a material volume coverage representation for the three-dimensional object. The halftone output is used to provide control data for instructing production of a three-dimensional object.

  • Publication number: 20180011675
    Abstract: According to an example, a system for electronic display illumination comprises a display, a sensor communicatively coupled to the display to detect a user and a user eye gaze, and a processing resource communicatively coupled to the sensor. In some examples, the processing resource may determine an active screen area and an inactive screen area of the display based on the user eye gaze; instruct a display controller to adjust a display value of the inactive screen area; and transmit active screen area data to a secondary display.

  • Publication number: 20180009241
    Abstract: In one example in accordance with the present disclosure a media transport device is described. The device includes a number of drive rollers coupled to a frame. A number of media rollers are also coupled to the frame. The media rollers are in contact with, and rotated by, the number of drive rollers. Media rollers in a first set have a first diameter and media rollers in a second set have a second diameter that is different from the first diameter. The device also includes a number of pinch rollers coupled to the frame. The pinch rollers are in contact with the number of media rollers to form a number of nips through which media passes along a feed path.
