Embedded Ready To Use Hybrid Mesh Network For Iot Applications, Jérôme Elleouet, Emmanuel Helbert

Defensive Publications Series

Gathering data from IoT (Internet of Things) sensors requires a communication infrastructure. This infrastructure could rely on WiFi, LAN or other proprietary networks as well as on mesh networks using any kind of radio technology. Thus, these networks are a prerequisite to conveys this data. In addition, some IoT applications such as asset or human tracking requires a dedicated network of sensors as well. That means that the overall solution requires device provisioning, configuration, installation and maintenance, as well as devices and network planning, leading to huge cost due to manual installation, ad-hoc configuration and maintenance …

However, I/O workloads on such emulated systems can make use of direct device access or device assignment when …

Fast & Scalable I/O For Emulated Hpux, Maheshwara Aithal, Dinesh Thanumoorthy, Ranjith Vk

Defensive Publications Series

HPE has positioned containerized solution called c-UX (code named Kiran) which runs HPUX in emulated (Itanium hardware emulation on x86) mode as a futuristic solution for the margin rich UNIX business. The value of containerized HPUX is that it allows customers using legacy HPUX applications to continue running on x86 hardware. Significant effort has been expended to increase the effectiveness of hardware resource utilization on c-UX. The next step in fully optimizing I/O in c-UX environment is to provide truly scalable high-performance, by enabling a single I/O device to provide DMA for multiple VMs. This scalability challenge can be solved …

A Novel Encoding & Alignment Of Histograms Of Referential Integrity Columns For Scalable Data Generation, Suresh Soundararajan

Defensive Publications Series

Testing the performance of database management systems is often accomplished using synthetic data and workload generators such as TPCH and TPCC. However most synthetic benchmarks don’t fully match customer database configurations. Customer database configuration data-sets are typically hard to obtain due to their sensitive nature and prohibitively very large sizes. As a result, oftentimes the data management systems are not thoroughly tested, and performance related bugs are commonly discovered after deployment, where the cost of fixing is very high. We propose a scalable data generator called XGen, an approach to generating data-sets out of customer metadata information, including integrity …

Using Device Movement For Multi-Factor Computing Device Authentication, Isaac Andres

Defensive Publications Series

A mobile computing device such as a smartphone may allow a user to confirm their identity during an authentication process by moving their phone according to a specified authentication gesture. The authentication gesture may be one that the user previously specified during an enrollment process and may otherwise be secret (e.g., the computing device may prompt the user to “Move the phone according to your secret authentication gesture”). In another example, the computing device may specify a type of authentication gesture for the user to perform (e.g., the computing device may prompt the user to “Move the phone in a …

Techniques For Efficient And Consistent Hashing With Optimal Fairness For Flow Distribution And Load-Balancing, Pierre Pfister, Mark Townsley, Yoann Desmouceaux, Aloys Augustin

Defensive Publications Series

Techniques are described herein that improve software network load balancers by enforcing optimal fairness at the end of the computation of the consistent-hashing table. By employing the techniques described herein, upon reconfiguration of server backends, the number of impacted overhead flows will be very low, while still providing optimal fairness. Moreover, the described techniques are very fast to execute, and can run without a flow-table or a relatively large table. The described techniques may be a good candidate for hardware load-balancer and Equal Cost Multi-Path (ECMP) implementations.

Battery Charge Level Based On Power Source Availability, Thierry Strudel

Defensive Publications Series

Maintaining the voltage of a consumer-device battery at near-maximum levels causes premature battery degradation. If kept fully charged for excessive amounts of time, the battery can swell, damaging the device enclosure and causing safety problems. However, users legitimately fear the draining of device batteries before a power socket is available, and hence keep devices plugged in beyond recommended durations.

The techniques of this disclosure monitor the availability of a power source, and accordingly set the maximum charge level such that battery life is optimized. For example, if power sources are amply available, the maximum allowed charge level is relatively low. …

Heat Removal From High Temperature Hardware While Shielding Electromagnetic Interference, Yao Xue, Eugene Fox

Defensive Publications Series

For devices with space constraints or lower heat generating components, connecting the heat generating component to another larger body, such as the enclosure metal, is a common heatsink solution. To ensure that the device antenna can function correctly, electromagnetic noise of the component is usually shielded by encapsulating the component with a grounded metal shield. For efficient heat dissipation, the number of intermediate items in the heat conduction path can be reduced by removing the shield cover or cutting a hole in the shield in order to sandwich a pad of conductive material between the component and the heatsink. While …

Defensive Publications Series

Techniques are presented to avoid requiring network administrators to have Spanning Tree Protocol (STP) domain specific knowledge while still achieving a stable and high performing Layer 2 (L2) topology in their Virtual Local Area Networks (VLANs). Configuring the STP is easily ignored since it is operable initially, but networks might run at a suboptimal efficiency as a result.

Defensive Publications Series

By using a general protocol that allows for sharing of bidirectional forwarding detection (BFD) state across a shared path between neighboring routers, scale, simplicity and flexibility in designs may be achieved with at least a 2:1 ratio compared to a traditional implementation. Each participating node hosts BFD sessions that monitor a locally attached link and then shares the state of the BFD sessions to other neighboring nodes, effectively proxying the BFD state for consumption by participating devices in an efficient manner.

Sound-Based Classifier For Domain Specific Language Model Selection, Anonymous

Defensive Publications Series

Providing correct responses to spoken commands issued to voice-activated devices depends on such devices recognizing the commands accurately. General language models that are agnostic to functional domains have lower quality of speech recognition.

Maximum Power Point Tracking Using Test Cell(S) In Solar Array(S), Anonymous

Defensive Publications Series

Solar arrays provide power to loads and are operated at their maximum power point (MPP) to optimize the power output from the solar arrays under various environmental and operating conditions. Maximum power point tracking (MPPT) techniques control operating conditions so that the solar arrays are at or near the MPP. However, MPPT techniques search for the MPP by repeatedly changing the voltage/current load of the solar array, until an operating point is determined that produces the maximum power at a given time. However, the process of repeatedly changing the voltage/current load for the entire array results in the entire array …
