  • Publication number: 20200050942
    Abstract: An example system and method facilitate enabling precise answers to technical support questions pertaining to a given computing environment, e.g., a cloud-based enterprise computing environment. The example method includes using an overtrained recurrent neural network employing Long Short-Term Memory (LSTM) cells to selectively answer specific questions by providing precise answers to technical support questions. A second neural network that is not overtrained can provide more generalized answers when a confidence measurement of an answer of the first neural network falls below a predetermined threshold. Furthermore, expert staff, e.g., developers and/or engineers that may be able to more precisely answer a specific question may be shown the answer. Subsequent expert answers or modifications to existing answers may be used to further refine the neural networks, e.g., via periodic supervised learning.

  • Patent number: 8797372
    Abstract: The present invention provides a device and method for controlling screen brightness. The method comprises: a light sensor acquiring a brightness signal intensity value of external environment and transmitting the brightness signal intensity value to a comparator; the comparator comparing the received brightness signal intensity value with a stored brightness signal intensity value and outputting a comparison result to an integrator; if the comparison result is that the received brightness signal intensity value is greater than the stored brightness signal intensity value, the integrator increasing the stored brightness signal intensity value by a fixed value according to the comparison result; and if the comparison result is that the received brightness signal intensity value is less than the stored brightness signal intensity value, the integrator decreasing the stored brightness signal intensity value by a fixed value according to the comparison result.

  • Patent number: 8594111
    Abstract: The present invention discloses a method for buffering a cell by a crossbar switching matrix, which includes: sending a jitter timestamp to a switching port connected to the crossbar switching matrix through a link, and receiving a cell that is sent by the switching port and carries the jitter timestamp, in which the jitter timestamp indicates a jitter of the link itself; and using a sum of the jitter timestamp carried in the cell and a relative delay timestamp of the corresponding link as a total timestamp, and storing the cell in a buffering unit corresponding to the total timestamp in a cell buffer of the link, in which the relative delay timestamp indicates a difference of a delay of the link relative to a delay of a lowest link.

  • Patent number: 7716494
    Abstract: A trusted platform in a digital processing system is maintained even when modules, or other processes or data, are loaded after a boot sequence. A configuration file is used to include measurements (e.g., hash values, signatures, etc.) of modules to be loaded. After secure boot-up the operating system kernel uses the configuration file to check module integrity prior to loading and executing. If a module does not verify against the configuration file data then the system can prevent further operation, restrict certain operations, indicate the non-trusted nature of the system or take other actions. In one embodiment, if a module does not pass the integrity check then the failed measurement is extended into a specific Platform Configuration Register (PCR) within a Trusted Platform Manager (TPM) process. Subsequently, client applications can determine if the platform is trustable based on the return of the PCR value.

  • Patent number: 7552326
    Abstract: A system to manage and control usage rights for cryptographic keys. A kernel process is provided with secure and exclusive authorization to access certain keys in a key hierarchy. Special authorization is required for other processes or users to access keys used by the kernel. A persistent storage area is used to hold a Kernel Authorization Data field for the root key and/or other keys used by the kernel or other specialized processes. The authorization data, and the keys it protects, can be used to protect other portions of, or the entire, key structure. The persistent storage area is reserved in a TPM or similar security hardware.
