Online Cascaded Deduplicating, Yotam Intrator, Regev Cohen

Defensive Publications Series

Real-time deduplication of search results is beneficial in the field of information retrieval. This process can deliver unique and relevant outputs to users with minimal delay. For instance, if a news aggregator is processing hundreds of incoming articles each hour, it can use an online deduplication process to sift out redundant content.

Present methods often rely on offline deduplication, which may not scale well for massive, frequently updating data streams. Repeated entries can diminish user satisfaction by cluttering query outputs with similar or identical items. Large-scale, real-time deduplication can help address this by filtering exact duplicates and improving clarity, although …

Intuitive Gesture-Based Intent Specification For Search Workflows, Gulmohar Khan, Ramprasad Sedouram

Defensive Publications Series

Many search applications support multimodal search where results in different modalities are delivered. In some contexts, search results may also include AI-generated content that is responsive to a user query. However, current user interfaces for search do not enable a user to easily specify their intent, e.g., web results vs. generative results; text-only, image-only, video-only results, etc. This disclosure describes an intuitive, gesture-based user interface that enables users to specify their search intent when initiating a search. The gesture may be performed with reference to a user interface element such as a call-to-action button, a virtual keyboard, a dropdown menu, …

Transforming Physical Objects Into Interactive Interfaces Using Hand Tracking, Ruofei Du, David Kim

Certificate Authority As A Global Attestation Verifier Service, Nelly Porter, Rene Kolga

Defensive Publications Series

An attestation verification service (AVS) enables remote attestation of hardware-based trusted execution environments. However, today the confidential-computing industry lacks AVS that is independent, trusted, cross-technology, and cross-cloud. This hampers the adoption of and trust in confidential computing services. This disclosure describes techniques that leverage a certificate authority (CA) to provide independent and technology/cloud-agnostic attestation verification service (AVS). Per the techniques, the AVS provided by the CA collects certificates from vendors or entities in specific trust chains, e.g., hardware vendors, cloud service providers, etc. The AVS verifies certificates (signatures) from each entity and signs the overall endorsement report with its own …

Multibit Synchronizer For Ultra-Low-Power Multi-Clock System-On-Chip, Kanishka De, Sheng Lin

Defensive Publications Series

Modern low-power system-on-chip (SoC) designs reduce power consumption by using multiple asynchronous clocks that can run different chip blocks at their optimal DVFS (dynamic voltage frequency scaling) points. However, this causes significant increases in instances of data paths crossing asynchronous clock domains. At such crossover points, synchronizer is used in the design to address metastability issues. Typically, the synchronizer cells comprise two or three stages of flip-flops, but such synchronizer cells are implemented as single-bit standard cells. As a result, the design is restricted from achieving a higher multi-bit grouping ratio and a better performance-per-Watt. This disclosure describes a multibit …

Techniques To Facilitate Fast Link Protection Switch Convergence For Routed Passive Optical Networking (Pon) Networks, Manoj Kumar, G T Nadiyan Selvam

Defensive Publications Series

Proposed herein are techniques that enable the propagation of an event from a passive optical networking (PON) segment to an Ethernet segment through the use of a link level protocol (e.g., Link Layer Discovery Protocol (LLDP)). During operation for a PON deployment, when a PON Media Access Control (MAC) layer component takes over a PON link as a new active link, an event can be sent to the far end provider edge (PE) of the Ethernet overlay circuit to enable a path switch from an earlier active path to the protect path. Thus, the proposed techniques may enable fast end-to-end …

Novel Test Point Algorithm For Register-Based Read Only Memory, Krunal Siddhapathak, Ankit Garg

Defensive Publications Series

This publication describes a test point algorithm that uses custom test points to detect faults at a given node in a register-based read-only memory (ROM). Test points to detect faults are inserted at higher combinational depth levels to reduce the overall number of test points used. In some implementations, a combinational depth is calculated, test point nodes are identified, and duplicates are sorted and removed. A flop-based ROM implementation may include address‑decoding logic to obtain specific register content. A flop-based ROM implementation may include an OR tree structure to generate the final ROM output.
