Abstract: A desktop computing system having at least a central core surrounded by housing having a shape that defines a volume in which the central core resides is described. The housing includes a first opening and a second opening axially displaced from the first opening. The first opening having a size and shape in accordance with an amount of airflow used as a heat transfer medium for cooling internal components, the second opening defined by a lip that engages a portion of the airflow in such a way that at least some of the heat transferred to the air flow from the internal components is passed to the housing.

Abstract: A reusable cup lid may be configured for attachment to a beverage container. The cup lid may define a body housing a battery, motor and fan operably connected. A removable cover may include a control circuit with an LED display operably connected to settings and programming buttons. The cup lid may include a drinking port and a venting channel. A charging/external power port may provide for connection directly to an external power source for charging or powering the cup lid. An attachment member may be mounted on the rim of a cup providing a watertight seal. The cup lid may be removably connected to the attachment member.

Abstract: The invention relates to a method for positioning an unmanned aerial vehicle, in which the actual position (25) of the aerial vehicle differs from a desired position (26) and in which the aerial vehicle is set in a corrective motion in the direction of the desired position (26) on the basis of a first piece of directional information (27). After the beginning of the corrective motion a second piece of directional information (28) is obtained. The first piece of directional information (27) is corrected on the basis of the second piece of directional information (28). The invention moreover relates to an aerial vehicle suitable for performing the method. The invention allows a specific corrective motion in the direction of the desired position.

Abstract: A capacitive sensing system based on projected self-capacitance is suitable for use in printing systems/products to sense paper tray status. In example embodiments, a capacitive sensing system is adapted for sensing the condition/characteristics of paper in the paper tray, such as paper size, stack height and page count and paper dielectric. The capacitive sensing system can be configured with one or more shielded capacitive sensors incorporated into the paper tray, and oriented relative to the paper according to the paper condition/characteristic sensed.
