Abstract: Replicas are selected in a large distributed network, and the roles for these replicas are identified. In one example, a leader is selected from among candidate computing clusters. To make this selection, an activity monitor predicts or monitors the workload of one or more clients. Different activities of the workload are given corresponding weights. The delay in performing requested activities, modified by these weights is found, and the candidate leader with the lowest weighted delay is selected as the leader.

Abstract: A method of controlling a color display screen aboard a motor vehicle includes performing, via a host computer, a color calibration test of a user of the motor vehicle in which the user is subjected to a calibrated set of color-coded test information. The method includes receiving a color perception response of the user to the calibrated set of color-coded test information via the host computer. Additionally, the method includes mapping a reduced visual gamut of the user via the host computer using the color perception response, and then commanding adjustment of user-specific color settings of the motor vehicle using the reduced visual gamut to thereby accommodate a color perception deficiency of the user.

Abstract: This document describes systems and techniques for facilitating spatial rediscovery using on-device hardware. For example, an audio input mechanism associated with a compact device can be activated and an audio signal can be generated by an audio output mechanism associated with an external device. The audio signal can be received at the audio input mechanism associated with the compact device. The receipt of the audio signal may cause the audio input mechanism to produce electrical signals having encoded information associated with the audio signal. The electrical signals can then be transmitted to the external device as wireless signals. Based on an analysis of the transmitted wireless signals, a spatial positioning of the compact device relative to the external device can be determined. Based on the determination of the spatial positioning, a location indicator can be provided via the external device.

Abstract: A technology to identify processing paths of untrusted input data received by applications that are vulnerable to attacks and to further detect and prevent actual attacks that try to exploit those vulnerabilities is disclosed. Application code is augmented at run-time with sensor code which detects the entry of input-data into the application and further traces the propagation, manipulation and, sanitization of this input-data until its usage in a data sink. The so generated data-flow traces reveal data-flow paths that lack required sanitization measures to neutralize potentially harmful input-data. Such data-flow paths are reported as vulnerabilities. Further, input-data that reaches data-sink interfaces is scanned by data-sink sensors to identify harmful input data. On identification of harmful input data, an attack is reported, and countermeasures are applied to prevent the identified attack.

Abstract: A split volute for a centrifugal pump is disclosed that provides a manufacturing advantage by improving the yield of high-chrome iron casting, providing for full surface coating capability using line-of-sight spray coating systems. Performance improvements include improved pump efficiency, abrasion resistance, and volute lifetime. Additional operational cost savings are enabled through reduced time required for common volute maintenance procedures and an increased replacement interval for the volute. Taken together, these advantages reduce the total cost of ownership of the split volute pump system.

Abstract: A safe, quiet, easy to control, efficient, and compact aircraft configuration is enabled through the combination of multiple vertical lift rotor assemblies, tandem wings, and forward thrust propellers. The vertical lift rotor assemblies, in combination with a front and rear wing, permits a balancing of the center of lift with the center of gravity for both vertical and horizontal flight. This wing and multiple rotor system has the ability to tolerate a relatively large variation of the payload weight for hover, transition, or cruise flight while also providing vertical thrust redundancy. The propulsion system uses multiple lift rotor assemblies and forward thrust propellers of a small enough size to be shielded from potential blade strike and provide increased perceived and real safety to the passengers. Using multiple independent rotor assemblies provides redundancy and the elimination of single point failure modes that can make the vehicle non-operable in flight.

Abstract: In one embodiment, a method receives a downstream signal and an upstream signal in a same frequency band. The downstream signal and the upstream signal are separated into a first path and a second path. The downstream signal using the first path and the upstream signal using the second path are amplified in an analog domain. The method isolates the downstream signal and the upstream signal from one another and sends the downstream signal downstream to a subscriber device and sends the upstream signal towards a full duplex node.
