Identifying Application And Traffic Patterns Contributing To Microbursts And Congestion In Data Center Networks, Saravanan Sampathkumar, Ajay Modi, Sandeep Sreerangam, Umamaheswararao Karyampudi, Ashish Singh

Defensive Publications Series

Microbursts are traffic events that can cause severe performance degradation in a network. With the advent of modern big data applications, microburst events are not uncommon in a data center. Rather than attempting superficial ad-hoc solutions, such as providing large buffer switches/routers, under provisioning bandwidth, etc., this proposal provides a technique to identify an offending application causing a microburst based on queue-level thresholds. Once identified, appropriate remedial action(s) (e.g., Quality of Service (QoS) actions, security actions, etc.) can be performed by a network administrator.

Scheduling Policy For Burst Multithreading, N/A

Defensive Publications Series

Modern computers have many CPU cores, but unless the problem to be solved is highly parallel, these CPU cores cannot be used efficiently: some cores are often left sitting idle while the others perform the bulk of the computation. Even for highly parallel problems, for small procedures, the overhead of requesting a thread to receive the processing request and begin execution is comparable to the time of execution thus resulting in little to no benefits from parallel execution. This disclosure describes techniques to improve the efficiency of communications between threads by reducing overhead. Per the techniques, the runnable threads of …

A Failure Predictive Algorithm Using Sequence Of Event Codes With A Deep Learning Model (Lstm), Hp Inc

Defensive Publications Series

We are building a failure prediction algorithm with sequences of event code data from devices

using a deep learning model called LSTM (Long Short‐Term Memory). LSTM models are widely

used to predict the sequence of words in word embedding technique. The principle idea of this

algorithm is very similar to next word prediction in your cell phone when you are sending

messages. The algorithm has the ability to predict the event codes leading up to the failure and

resulting time of the failure. The algorithm is fed a list of the last five event codes on the specific

device and …

Cost Saving By Reducing One Of The Multiplexers Required To Enable Docked Pre-Boot External Display Support, Hp Inc

Defensive Publications Series

Some pre-boot features only work with UMA graphics today on Windows based system. Displays on

docks may be driven by either the UMA or Discrete Graphics. In order to support pre-boot features

on displays attached through the dock, platforms with discrete GPU will need to switch to UMA

graphics during pre-boot. A possible mechanism for this switch is using display multiplexers. We

propose a method that reduces the number of required multiplexers, saving cost and board space.

Easy Plug-In Ink Collector Module With Magnets For Textile Large Format Printer, Hp Inc

Defensive Publications Series

In our large format printers, an ink collector accessory is used to enable the possibility of printing onto

porous substrates (textiles for example). Nowadays the set‐up process consists on placing some ink

collector modules on top of the print‐platen of the printer. To secure those ink collector modules, the

user must manually rotate up to 18 latches, which can be quite annoying and time‐consuming for

him/her. In addition to that, there is a failure mode on the field related to a misuse of those latches that

can result in broken parts, and therefore, in a service intervention to repair the …

High Capacity Ink Collector For Textile Printing On Porous Medias Based On Sloping Plates, Hp Inc

Defensive Publications Series

Textile printing, and specifically digital textile printing is becoming more important in the industry

the last years mostly because of the improvement in the versatility, customization and time

reduction between first designs and the introduction to the market. In some application (e.g. dye

sublimation) the workflow requires to print in some paper media and transfer the ink to the textiles

by means of a calender (external machine). On the other hand, in some other applications, direct

printing ("Direct To Fabric" or DTF) on the textile media is possible (e.g. fashion, decor, some soft

signage). In some of these DTF applications …

A Zero Cross Detection Method For Ac Power Converters Based On An Extended Kalman Filter, Hp Inc

Defensive Publications Series

We disclose a new method for the joint detection of phase, frequency and amplitude of AC line voltage

that can outperform existing solutions in terms of detection precision and robustness to noise and

distortions on the AC line. This method is a fundamental building block in digitally controlled AC/AC

power converters, allowing them to operate with a tight adaptation to the input AC voltage, which in

turn brings more efficiency, more precise output control, and less conversion outages due to input AC

variations.

Defensive Publications Series

Proposed herein is a technique to utilize a sequential analysis to map the probability of a sequence of commands executed via Command Line Interface (CLI) in order to determine a root cause of a problem in a network. This technique may provide different paths that can be analyzed in order to debug an issue. The sequential analysis may be performed in tandem with an interpreter model that may read text generated by each command, verify whether there is any problem in a sub-segment, and, upon determining a problem, may enable automatic remediation to the problem.

Data Compression Using Pre-Generated Dictionaries, Simon Cooke

Defensive Publications Series

A file is compressed by replacing its characters by codes that are dependent on the statistics of the characters. The character-to-code table, known as the dictionary, is typically incorporated into the compressed file. Popular compression schemes reach theoretical compression limit only asymptotically. Small files or files without much intra-file redundancy, either compress poorly or not at all. This disclosure describes techniques that achieve superior compression, even for small files or files without much intra-file redundancy, by independently maintaining the dictionary at the transmitting and receiving ends of a file transmission, such that the dictionary does not need to be incorporated …

Efficient Wireless Charging Of Peripheral Devices, Liang Jia, Yungchih Chen

Defensive Publications Series

Wireless charging is an attractive charging option for peripheral devices like styluses, digital pens, etc. The peripheral devices are commonly charged using the main computing device as a power source. The main device uses an induction transmit coil (Tx coil) to create an alternating electromagnetic field, which a receiver coil (Rx coil) in the peripheral device converts into electricity to be fed into a battery in the peripheral device. Magnets are provided at suitable locations on the peripheral device and the main device to align and attach the peripheral device to the main device, thereby reducing the air-gap between Rx …
