Out-of-app based partner aware user authentication
An app runs on a user operated computing device, e.g., a mobile device running a sandboxed operating system. The app requests a session ID from a publisher Idp. The app registers for notifications on the session ID with a notification service. The app directs a browser to navigate to the publisher IdP, and to pass it the secure session ID and an ID of a specific partner. The publisher IdP returns a redirect to a third party IdP used by the specific partner to authenticate users. The browser navigates to the third party IdP, which prompts the user for authentication credentials. The third party Idp uses the credentials to authenticate the user, and redirects the authentication result to the publisher IdP. The publisher IdP sends the app a notification, via the notification service. In response, the app calls the publisher IdP, and receives a secure authentication token. |

High-performance virtual machine networking
A method for conveying a data packet received from a network to a virtual machine instantiated on a computer system coupled to the network, and a medium and system for carrying out the method, is described. In the method, a guest receive pointer queue of a component executing in the virtual machine is inspected in order to identify a location in a guest receive packet data buffer that is available to receive packet data. Data from the data packet received from the network is copied into the guest receive packet data buffer at the identified location. A standard receive interrupt is raised in the virtual machine. Thus, the kernel places the data packet received from the network into a memory space accessible to the virtual machine without any intervention by a virtual machine monitor component of the virtualization software. |

Different numbers of delay slots are assigned by a compiler/scheduler to each different type of jump operation in a pipelined processor system.

Different types of jump operations resolved their target addresses in different numbers of delay slots. As a result, the compiler/scheduler is able to generate more efficient code than for a processor with a fixed number of delay slots for all jump types, resulting in better processor performance. |

Compression of floating-point data
Compression of exponents, mantissas and signs of floating-point numbers is described. Differences between exponents are encoded by exponent tokens selected from a code table. The mantissa is encoded to a mantissa token having a length based on the exponent. The signs are encoded directly or are compressed to produce fewer sign tokens. The exponent tokens, mantissa tokens and sign tokens are packed in a compressed data packet. Decompression decodes the exponent tokens using the code table. The decoded exponent difference is added to a previous reconstructed exponent to produce the reconstructed exponent. The reconstructed exponent is used to determine the length of the mantissa token. The mantissa token is decoded to form the reconstructed mantissa. The sign tokens provide the reconstructed signs or are decompressed to provide the reconstructed signs. The reconstructed sign, reconstructed exponent and reconstructed mantissa are combined to form a reconstructed floating-point number. |

One or more devices in a provider network receive a notification that a border controller (SBC) device has failed and, in response to the notification, modify a backup SBC configuration file for the failed SBC device to create a modified backup configuration file, where the modified backup configuration file replaces carrier-side Internet Protocol (IP) addresses of the failed SBC device with carrier-side addresses of a failover SBC device. The devices send the modified backup configuration file to the failover SBC device to configure the failover SBC device and send a backup router configuration file for a local router associated with the failed SBC device to a local router associated with the failover SBC device, where the backup router configuration file is to configure the local router associated with the failover SBC. The devices also provide, to a domain name system (DNS) server, carrier-side IP addresses for the failover SBC device to replace IP addresses associated with fully-qualified domain names (FQDNs) of the failed SBC device. |

Optical information reproduction apparatus using homodyne phase diversity detection with improved SNR
In the optical information reproduction apparatus using Homodyne phase diversity detection, the S/N ratio of a reproduced signal is deteriorated due to the influence of a quantization noise generated in an A/D converter for digitalizing a differential signal. The optical information reproduction apparatus is arranged to have the A/D converter for digitalizing the differential signal having a vertical resolution equal to or higher than 9 bits. |

Optical disc drive high frequency modulation signal detection
In a method of correcting a channel bit pattern that violates bi-phase modulation constraint in a bi-phase modulated portion of a high frequency modulation (HFM) signal, a sequence of channel bits is recovered from the HFM signal. The recovered sequence of channel bits is analyzed to generate a bi-phase modulation compliant sequence of channel bits based on the recovered sequence of channel bits, wherein the bi-phase modulation compliant sequence of channel bits does not violate the bi-phase modulation constraint in the bi-phase modulated portion of the HFM signal. Bi-phase modulated HFM bits are recovered from the bi-phase modulation compliant sequence of channel bits to generate a detection output corresponding to the recovered bi-phase modulated HFM bits. |

Monolithic flexure pre-stressed ultrasonic horns
A monolithic ultrasonic horn where the horn, backing, and pre-stress structures are combined in a single monolithic piece is disclosed. Pre-stress is applied by external flexure structures. The provision of the external flexures has numerous advantages including the elimination of the need for a pre-stress bolt. The removal of the pre-stress bolt eliminates potential internal electric discharge points in the actuator. In addition, it reduces the chances of mechanical failure in the actuator stacks that result from the free surface in the hole of conventional ring stacks. In addition, the removal of the stress bolt and the corresponding reduction in the overall number of parts reduces the overall complexity of the resulting ultrasonic horn actuator and simplifies the ease of the design, fabrication and integration of the actuator of the present invention into other structures. |

Partitioned erase and erase verification in non-volatile memory
A set of memory cells can be erased by individually erasing portions of the set in order to normalize the erase behavior of each memory cell and provide more consistent erase rates. An erase voltage pulse can be applied to the set of memory cells with a first group of cells biased for erase and a second group biased to inhibit erase. The erase depth is made shallower as the device is cycled more. |
