Abstract

In an example of the disclosure, a priming lane and a non-priming lane are identified within an image frame to be printed by a printer. A line of molten wax is applied to the roller. The molten wax when cooled is to form a wax ridge upon the roller. The roller having the formed wax ridge is wetted with the primer. The wetted roller is rotated against the substrate to apply the primer. A first width of the wetted roller that does not include the wax ridge forms the priming lane upon the substrate. A second width of the roller that includes the wax ridge causes the primer to not transfer and thereby forms the non-priming lane upon the substrate.

Abstract

An example display system includes an on-screen display (OSD) circuit, an input/output (I/O) controller, and a map engine. The OSD circuit operates a functionality of a display device. The I/O controller routes input from a peripheral device to the OSD circuit when the OSD mode is active. The map engine causes activation of the OSD mode when an input sequence received by the I/O controller corresponds to an OSD mode activation sequence.

Abstract

An apparatus includes an integrated camera/scanner system built into the display housing of a display device. The apparatus includes a camera housing contained within the display housing. A door is attached to the camera housing in a pivoting manner. A minor is affixed to a planar surface of the door, where the planar surface faces inward into the camera housing. A camera is housed within the camera housing. The camera is mounted in the camera housing in a manner that allows the camera to pivot to adjust an angle of image capture. An actuator moves the camera housing in and out of the display housing.

Abstract

A device to thermoelectrically cool a cooling fluid is described. The device includes a cooling fluid circulation system to circulate a cooling fluid which cools a hardware component of a computer. The device further includes a thermoelectric cooling unit to cool the cooling fluid. The device further includes a controller to execute temperature control instructions to control the thermoelectric cooling unit to cool the cooling fluid to a cooling temperature not lower than ambient temperature to reduce the risk of water condensation.
