Piping Powder Detection System, Hp Inc

Defensive Publications Series

In some 3D printing systems, after printing, powder must be recovered from the build unit, and

transported to the storage tanks so that it can be sieved and then loaded again for the next job. To

perform this, multiple circuits of pipes are needed from volume to volume.

With the introduction of new materials and the option of switching from one to another, it is

important to guarantee that the system is clean from the previous material before loading the new

one to ensure quality and that the printed parts will have the expected mechanical properties.

Currently the process used …

A Method To Reduce The Number Of Triangles Of A Mesh To Allow Its Fluent Visualization In A 3d Printer Control Panel, Hp Inc

Defensive Publications Series

This invention disclosure proposes a method for generating a reduced size mesh from a printresolution

mesh received in a 3D printer. The 3D printer receives the content to be printed by means

of triangle meshes. To be able to provide the required printing resolution, the number of triangles

conforming the 3D part can be quite high, leading to high memory and processing requirements

when aiming to manipulate the model. Previewing the 3D model of the part on the printer control

panel can lead to a non-responsive User interface and even impact the performance of the printer

firmware because there is …

A Mechanism To Audit 3d Geometries Submitted For Printing In A 3d Printer, Hp Inc

Defensive Publications Series

This disclosure proposes a mechanism for auditing the content being printed in a 3D printer. It is

based in a digital signature so that some user with appropriate privileges is able to digitally sign the

parts validated by himself. This validation can be done both in the pre-print Software application or

in the printer Control Panel. Then, the printer validates that all the parts conforming the job have been

validated by checking that the contain the appropriate digital signature. All the validations are stored

in an internal database using an audit trail mechanism.

3d Printer Platform Heaters Diagnostic Through Thermocamera Sensor, Hp Inc

Defensive Publications Series

In some 3D printers or other Additive Manufacturing technologies, parts are built by adding successive

layers of powder (plastic, metal or other composite materials) from a series of cross sections (slices),

which stick to each other creating the final part’s body.

In some printing solutions these layers are formed on top of a moving platform, in vertical axis. There is

also a scan axis which drops some agents to fuse and define (fusing and detailing agent or binder) the

parts printed through this printing process involving powder, agents and temperature.

All related to keep temperature uniform in X,Y and Z …

Process To Clean A Chamber Which Has Been Optimized For A Front Door System, Hp Inc

Defensive Publications Series

It is desirable to from a machine structural point of view to have a front door opening for user

access. It is also desirable to minimise a chambers volume to reduce the consumption of nitrogen for

inerting as well as other reasons. The chamber volume is normally reduced by minimising the height

of the chamber. This introduces a problem for user access for cleaning operations as the top of the

chamber is too low to allow ergonomic regular maintenance activities.

This article introduces a process where an internal skin is included within the chamber. After a build,

the powder settles …

Emoji Based On User Expression While Composing A Message, Bhuvana Hariharasubramanian

Defensive Publications Series

This disclosure describes techniques to extract real time facial expressions with the use of facial recognition techniques. When a user provides permission, a user device obtains an image of the user’s face and performs facial recognition to detect the facial expression of the user. Upon successful detection of the facial expression, the use of an emoji that represents the facial expression is suggested. For example, if it is detected that the user is confused while typing a reply to a message, an avatar or emoji that expresses confusion is sent to a recipient along with the message. The technique can …

Authenticating Walkup User For Secure Remote Webscan, Hp Inc

Defensive Publications Series

Remote WebScan is a feature which is increasingly used for digitization of physical data using Multi‐Function Print

Peripherals (MFPs) supporting a scanner bed. However, this brings forth potential security vulnerabilities such as

when the walkup user is not identical to the remote web‐scan client user; and hence could be a rogue user who

maliciously might try to disseminate scanned data in conjunction with the legal remote scan.

Fast Multi-Phase Trans-Inductor Voltage Regulator, N/A

Defensive Publications Series

Data centers employ powerful application-specific integrated circuits (ASICs) that consume significant amounts of current, e.g., up to a thousand amperes, and fluctuate rapidly in their power demand. Due to various factors, e.g., large output impedance, increasing space occupied by decoupling capacitors, etc., the multi-phase voltage regulator that traditionally supplies such loads is reaching the limits of its performance. This disclosure describes a multi-phase trans-inductor voltage regulator (TLVR). The TLVR is such that each of its phases has an output inductor that is the secondary winding of a transformer whose primary windings are all connected in a series loop. The phases …

Preload Documents On Printer For Faster Printing Response, Hp Inc

Defensive Publications Series

Discloses a process that can preload the most probable document choice (or part of it) into a

printer (or local server), so the printing process can initiate faster.

The proposed design can improve user printing experiences on platforms that have limited

feedback. For example, on voice assistant platforms the voice application is not allowed to start

interactions with the user, nor stay with the communication open for much time, thus when using

a web printing service, it can’t wait for the printer to start the job to give feedback for the user.

Enabling The Ability To Retrieve The Cancelled Job For A Defined Period, Hp Inc

Defensive Publications Series

A print queue is a list of print jobs held in a reserved memory area. It maintains the status of all

Pwa Printhead Servicing Based On Image Processing, Hp Inc

Defensive Publications Series

Page Wide Array printing system uses an array of printheads to print at one pass. Printheads are

perpendicular to the media advance axis. In these printing systems, the paper is moving during printing

while printheads are static above the paper. For that reason, there is no chance to do printhead servicing

between passes (like scanning printers) such as flying spit or wipe. Thermal inkjet printheads require

refresh nozzles from time to time to maintain its health. The only way to refresh nozzles while printing in

a PWA system is spitting on the page (SOP).

Usually, customers have various media roll …

Automatic Generation Of Native Ad Styles Using Visual Attributes Of Images, Bo Lin, Ravali Pochampally, Yunfan Yang

Defensive Publications Series

Native advertisements mimic the look and feel of a publisher’s content slots and are used to monetize their inventories. Currently, native ad styles are created manually by the publisher based on hand-written rules and heuristics. This can result in ad styles that do not consistently resemble the look-and-feel of the publisher’s pages or apps. Also, current techniques generally use the DOM structure or HTML source of the publisher’s page or app to generate the native ad. However, the DOM structure or HTML source is not always available, e.g., for apps.
