Warm Shifting To Reduce Drop Quality Degradation, Hp Inc

Defensive Publications Series

In some high‐speed print modes, it has been found that a warming pulse applied to a nozzle can have detrimental effects

on drop qualities ejected from that nozzle on subsequent firing. Simple logic is described which can shift a warming pulse from

being applied to a first nozzle to a neighboring second nozzle, thus preventing the detrimental effects on drop quality on drops

ejected from the first nozzle on subsequent firing. This logic requires minimal die area (low‐cost) and can operate autonomously so

that no integration with print system data path is required.

Dynamic And Heuristic Method For Printing And Scanning Warm-Up Calculations, Hp Inc

Defensive Publications Series

Current Large Format Printers have fixed warm‐up periods for the printing and scanning

systems when measuring a test chart to profile a printer and when doing calibrations (color,

printhead alignment, media alignment). For instance, the chart we currently use for profile

measurements have some patches that are only used to warm‐up the printing system.

Similarly, we warm‐up the embedded spectrophotometer before taking measures. The length

of the printing warm‐up patches and the time we turn‐on the spectrophotometer is fixed and

based on a previous experience and/or knowledge. However, Printers and Scanners are

dynamic systems that have printing and scanning warm‐up …

Partial Mapping Of Abstract Rich Ui Model, Nicolas Roard, John Hoford

Defensive Publications Series

Visual UI editors generally have certain inflexibilities. For example, if a UI model is used to directly generate compilable code, a developer cannot modify the UI from the generated code. Further, tight coupling that exists between the UI model and the UI elements can make cross-platform development and reactive programming difficult, and can result in limited expressivity. This disclosure describes a rich, abstract, declarative UI model that encompasses layout, navigation, animation, and static visuals. The declarative UI techniques and partial scene mapping described herein can reduce developer workload and enable the building of two-way tooling, cross-platform development, gradual prototype-to-application evolution, …

The constraints may include resources such as Central Processing Units (CPUs), memory, bandwidth, network forwarding resources, etc. For example, compute-intensive applications may require more CPU resources, whereas some applications (e.g., logging) may require more memory. The constraint may also be a combination of multiple resources, such as a log collector analysis service.

Context-Aware Message Delivery With Sender-Specified Priority, Felix Weissenberger, Victor Carbune

Defensive Publications Series

Solutions to manage incoming messages such as email, chat, etc. put the burden on the message recipient. In the absence of cues from the message sender about the urgency and/or importance, the recipient cannot determine whether a message requires immediate attention without reading the message first. As a result, many users hesitate to adopt solutions that defer message delivery or notification out of a fear of missing an urgent message that requires prompt action. This disclosure describes techniques to provide message senders capabilities to augment sent messages by specifying additional information, such as priority and contextual delivery parameters. Recipient applications …

Spatially Separating Participant Audio In A Conference Call, Jakob Zwiener, Marcos Calvo Lance, Jakub Kriz

Defensive Publications Series

The audio signal transmitted by the far end of a conference call or video conference is typically received at the near end as a composite signal that is the sum of the audio signals of the far-end participants. Far-end participants are therefore not spatially separable at the near end. This prevents near-end participants from using the natural focusing abilities of the brain (cocktail party effect) to focus on the speech of particular far-end participants. This disclosure describes techniques, e.g., per-microphone audio channels, speech diarization, etc., that distinguish far-end participants such that their audio is spatially separated at the near end.

Fly-Eye Structures For Increasing Microled Light Extraction, Anonymous

Defensive Publications Series

This disclosure describes fly-eye nanostructures for increasing light extractions from semiconductor layers of micro light emitting diodes (microLEDs). Disposing a fly-eye nanostructure layer on a semiconductor layer having a high refractive index increases the percentage of light that escapes an air-to-semiconductor interface when the semiconductor layer has a high refractive index. As a result, the efficacy of light emitting semiconductors is improved. From a plan view, the fly-eye nanostructures include raised structures that may appear similar to brain structures, a hedge maze, or a fingerprint. The raised structures may appear closely-packed, random, and sinuous.
