Abstract: White-balance is improved when printing on colored media, while minimizing the time and use of costly materials required by present approaches. In an embodiment, the typical solid white fill or background layer is altered by including in the white layer one or more of the other colors already available in the printer to shade this layer. Thus, a small amount of cyan, for example, helps balance a pink-ish (red) media; yellow is used for blue media; and magenta is used for green media; as well as combinations thereof. A combination of transparent process inks and opaque white helps to maintain brightness (luminosity).

Abstract: Determining pace or speed based on sensor data may include determining an amount of contact time a user's foot has with a workout surface such as the ground. Contact time may be determined by identifying samples in the sensor data that correspond to various events such as a heelstrike, a toe-off and a subsequent heelstrike. In one example, these events may be identified by determining a sequence of three sample values (e.g., a triplet) that exceeds corresponding thresholds. The validity of an identified triplet (e.g., heelstrike, toe-off and heelstrike) may be confirmed by determining whether a difference between a last event sample and a middle event sample is greater than a difference between the middle event sample and an initial event sample. Once confirmed, a contact time may be determined from the triplet. A linear or non-linear relationship may then be applied to the contact time to determine a speed or pace.

Abstract: A liquid discharge apparatus includes a head array including heads each having nozzles to discharge liquid onto a recording medium, arranged as a nozzle line in a sub-scanning direction; a moving part to move the head array alternately in the scanning direction and in the sub-scanning direction perpendicular to each other while discharging or not discharging the liquid; and a controller including a memory and a processor. The processor adjusts image data for juncture areas of two heads adjacent to each other in the sub-scanning direction; and drives the head array to discharge the liquid from the nozzles while the moving part moves the head array. The adjusting adjusts the image data such that the image data is thinned to make print rates for the juncture areas smaller at ends of the nozzle lines, and the print rates vary among the juncture areas.
