  • Method and apparatus for interception of synchronization objects in graphics application programming interfaces for frame debugging
    Patent number: 9910760
    Abstract: An aspect of the present invention proposes a solution for correctly intercepting, capturing, and replaying tasks (such as functions and methods) in an interception layer operating between an application programming interface (API) and the driver of a processor by using synchronization objects such as fences. According to one or more embodiments of the present invention, the application will use what appears to the application to be a single synchronization object to signal (from a processor) and to wait (on a processor), but will actually be two separate synchronization objects in the interception layer. According to one or more embodiments, the solution proposed herein may be implemented as part of an module or tool that works as an interception layer between an application and an API exposed by a device driver of a resource, and allows for an efficient and effective approach to frame-debugging and live capture and replay of function bundles.

  • Replaying events collected from a client computer
    Patent number: 9154365
    Abstract: Embodiments of the invention provide novel systems, methods and software for replaying one or more events occurring on a monitored computer (or elsewhere). Such solutions can provide the ability for an operator to easily determine the exact user behavior that produced the event and can, in some cases, and provide evidence of what the user did, and the order in which the user performed the various activities. Various embodiments of the invention organize various pieces of information captured from the user's client workstation behavior, reassemble of the pieces into a complete session of the users' activities and/or replay the exact user behavior for the observer, in some cases using a web browser and JavaScript to replay the activities just as they were performed by the original user.

  • Method and apparatus for evaluating for the purpose of decoding a bitstream having a data structure fulfilling the requirements of two different data structure standards, and storage medium containing such bitstream
    Publication number: 20040028387
    Abstract: There are different types of DVD systems, e.g. the replay-only DVD-Video system and the re-recordable DVD-VR system. A DVD-VR type disc containing a DVD-VR type bitstream is to be replayed on a DVD-VR type recorder or player. However, it is also possible to record a DVD-Video type bitstream on a DVD-VR type disc in a DVD-VR type recorder, for replay of that disc in a DVD-Video type player. Because the DVD-VR and DVD-Video formats are different and contain different content they are not compatible with each other and a disc containing a bitstream of the one type can not be replayed on a player of the other type, a user must make a choice of which type of bitstream recording on a disc. One solution to this problem would be to record a separate disc for each type of bitstream.

This special type of bitstream is compatible with the DVD-Video system as well as the DVD-VR system.

  • ALGORITHM TO PREDICT OPTIMAL WI-FI CONTENTION WINDOW BASED ON LOAD
    Publication number: 20210037569
    Abstract: A novel method that dynamically changes the contention window of access points based on system load to improve performance in a dense Wi-Fi deployment is disclosed. A key feature is that no MAC protocol changes, nor client side modifications are needed to deploy the solution. Setting an optimal contention window can lead to throughput and latency improvements up to 155%, and 50%, respectively. Furthermore, an online learning method that efficiently finds the optimal contention window with minimal training data, and yields an average improvement in throughput of 53-55% during congested periods for a real traffic-volume workload replay in a Wi-Fi test-bed is demonstrated.

  • FACIAL DATA COLLECTION AND VERIFICATION
    Publication number: 20210006415
    Abstract: The present application provides a facial data collection and verification solution. In this solution, after collecting a face sample, a collection device uses the face sample and check data including a random number as to-be-signed data, performs signature by using a device private key, to obtain a facial data signature, and then obtains trusted facial data based on the to-be-signed data, the facial data signature, and a digital certificate that includes a device public key. When performing verification on the trusted facial data, a facial recognition server sequentially performs verification on the digital certificate that includes the device public key, the facial data signature, and the check data. Because content used for the verification process is added for the face sample on the collection device, subsequent verification cannot succeed if a transmitted communication packet is replaced by an attacker. Therefore, a replay attack is prevented at the collection source.

  • MACHINE AND PROCESS FOR BRANCH SELF-GENERATION IN A CHANGE SERVER
    Publication number: 20200394037
    Abstract: A machine and process for branch self-generation in a change server that provide a technical solution via a practical application that reduces: a need for storage use in a memory, and a volume and time required for transmission of date responsive to inputs for creating, updating, querying, or deleting parts of a master baseline. The master baseline may serve utilities providing at least analysis, configuration, and allocations for a control unit in an object. The change server self-generates a branch utilizing a singular persistent imported baseline copy of the master baseline. Validation, export, and replay of the branch onto the master baseline eliminate a need for use of running exports to the master baseline through a differences analyzer.

  • Improvement to a Martial Arts Ring
    Publication number: 20180126251
    Abstract: The present utility model relates to the technical field of martial arts, and more particularly to a ring which is laterally surrounded by a rigid and transparent material. The proposed design aims to improve viewing for spectators and television viewers by allowing viewing, filming and photography from any angle without any obstructions, such as fencing, ropes or nets, which impede a clear view of a martial arts event. The present solution is also intended to benefit the dynamics of a fight by reducing clinch time and preventing a fighter from holding onto the fencing that currently surrounds a ring. In addition, there is the possibility of projecting images onto the outer side of the ring. In this case, spectators and television viewers will be able to view information such as, inter alia, competitor profiles, replays of fights, and sponsorship advertisements.

  • METHODS AND APPARATUSES FOR DISTRIBUTING KEYS FOR PTP PROTOCOL
    Publication number: 20130305048
    Abstract: The present invention provides a solution of automatically distributing PIP keys, and on that basis, provides a new encryption method. A domain control device is proposed to verify whether a network node is an eligible node in the domain; if the network node is an eligible node in the domain, then a key for the PTP protocol is sent to the network node. The methods and apparatuses according to the present invention enable access authentication of various forms of PTP network nodes, as well as the automatic configuration and dynamic sending of PTP keys, such that the security of the keys are significantly increased. Additionally, by means of SignCryption encryption algorithm, it is enabled that for each PTP message, not only message source authentication, message integrity authentication, message confidentiality, and replay protection can be provided, but also its sending network node can be tracked. Thus, the security is significantly increased.
