Abstract: In some embodiments, a method of provided boosted actuation to an aircraft flight control device includes receiving an input from a pilot input device via a mechanical input member, providing mechanical energy to a driving member of a controlled-slippage actuator, and varying the strength of a magnetic field applied to a magnetorheological (MR) fluid disposed between the driving member and a driven member of the controlled-slippage actuator based on the relative positions of the mechanical input member and a mechanical output member that is in mechanical communication with the driven member and the aircraft flight control device.

Abstract: One embodiment sets forth a method for allocating memory to surfaces. A software application specifies surface data, including interleaving state data. Based on the interleaving state data, a surface access unit bloats addressees derived from discrete coordinates associated with the surface, creating a bloated virtual address space with a predictable pattern of addresses that do not correspond to data. Advantageously, by creating predictable regions of addresses that do not correspond to data, the software application program may configure the surface to share physical memory space with one or more other surfaces. In particular, the software application may map the virtual address space together with one or more virtual address spaces corresponding to complementary data patterns to the same physical base address. And, by overlapping the virtual address spaces onto the same pages in physical address space, the physical memory may be more densely packed than by using prior-art allocation techniques.

Abstract: Cache lines in a multi-processor computing environment are configurable with a coherency mode. Cache lines in full-line coherency mode are operated or managed with full-line granularity. Cache lines in sub-line coherency mode are operated or managed as sub-cache line portions of a full cache line. Communications detected on a coherence interconnect may indicate that a cache line is associated with performance-reducing events. A high-contention cache line may be placed in sub-line coherency mode. Caches accessing the cache line are notified that the cache line is in sub-line coherency mode. The cache line may be associated with a counter in a centralized detection table that is incremented based on detecting the communications. The cache line may be a high-contention cache line when the counter satisfies a high-contention criterion, such as reaching a threshold value. The cache line may be returned to full-line coherency mode when a reset criterion is satisfied.

Abstract: Various exemplary embodiments relate to a method of preventing extreme coresidency hazards among application instances in a cloud network. The method includes determining a first failure group of a first instance of an application; establishing a connection with a second instance of a peer application; determining a second failure group of the second instance; comparing the first failure group to the second failure group; and establishing a second connection with a third instance of the peer application if the first failure group and the second failure group share a failure point.

Abstract: A system logs application usage data on a mobile device, processes the data on an analysis system and outputs a current and predicted score to, e.g. third parties. The system logs application-related usage data, which is collected via, e.g. a keyboard application running in the background on the mobile device. The system then evaluates the logged usage data and the events corresponding to a particular application. The events can be analyzed to score the user engagement level with the application, e.g., more events recorded for a given application per day, the more engaged a user is with that application. The engagement level can further be predicated based on historical usage log data from which a score decay model can be generated.

Abstract: Systems and methods for Secondary Cell (sCell) selection for wireless devices operating according to a carrier aggregation scheme in a cellular communications network are disclosed. In one embodiment, a network node obtains a list of potential sCells for a wireless device. The network node blindly selects an sCell for the wireless device from the list of potential sCells. The network node then configures the wireless device with the selected sCell. Blindly selecting the sCell for the wireless device makes it possible to avoid the use of measurement gaps and reduce throughput loss, according to some embodiments.

Abstract: Cache lines in a multi-processor computing environment are configurable with a coherency mode. Cache lines in full-line coherency mode are operated or managed with full-line granularity. Cache lines in sub-line coherency mode are operated or managed as sub-cache line portions of a full cache line. Each cache is associated with a directory having a number of directory entries and with a side table having a smaller number of entries. The directory entry for a cache line associates the cache line with a tag and a set of full-line descriptive bits. Creating a side table entry for the cache line places the cache line in sub-line coherency mode. The side table entry associates each of the sub-cache line portions of the cache line with a set of sub-line descriptive bits. Removing the side table entry may return the cache line to full-line coherency mode.

Abstract: Systems and methods are provided for using a personal finking graph. An electronic device obtains a first entity. It searches a links database, which includes one or more links between the first entity and other entities. The one or more links form the personal linking graph. The electronic device identifies a second entity associated with the first entity through the one or more links. An action related to the second entity is then performed. For example, the second entity is displayed.

Abstract: Implementations of the present disclosure may include calibration techniques for systems which include eye tracking devices and display devices. The calibration techniques may involve a calibration process which utilizes a plurality of visible calibration targets that each defines a gaze point for a user. The calibration targets may include both targets output to the display device, as well as gaze points located on the eye tracking device itself. The calibration techniques may also include additional sensors on the eye tracking device to gather additional calibration information, such as a back-facing camera which captures images of the display device from the eye tracking device. Increased information regarding system setup that is useful in calibrating the eye tracking system may be obtained from the calibration process.

Abstract: Cache lines in a multi-processor computing environment are configurable with a coherency mode. Cache lines in full-line coherency mode are operated or managed with full-line granularity. Cache lines in sub-line coherency mode are operated or managed as sub-cache line portions of a full cache line. A high-coherence-miss cache line may be placed in sub-line coherency mode. A cache line may be associated with a counter in a coherence miss detection table that is incremented whenever an access of the cache line results in a coherence request. The cache line may be a high-coherence-miss cache line when the counter satisfies a high-coherence-miss criterion, such as reaching a threshold value. The cache line may be returned to full-line coherency mode when a reset criterion is satisfied.

Abstract: The disclosed techniques relate to methods and apparatus for etching a substrate. A plate assembly divides a reaction chamber into a lower and upper sub-chamber. The plate assembly includes an upper and lower plate having apertures therethrough. When the apertures in the upper and lower plates are aligned, ions and neutral species may travel through the plate assembly into the lower sub-chamber. When the apertures are not aligned, ions are prevented from passing through the assembly while neutral species are much less affected. Thus, the ratio of ion flux:neutral flux may be tuned by controlling the amount of area over which the apertures are aligned. In certain embodiments, one plate of the plate assembly is implemented as a series of concentric, independently movable injection control rings. Further, in some embodiments, the upper sub-chamber is implemented as a series of concentric plasma zones separated by walls of insulating material.

Abstract: As exterior routing protocols generally do not provide information about the internal routing paths of an autonomous system, a particular autonomous system has limited information about the internal health of other autonomous systems. However, if a monitoring system has access to routing data and/or other network data from multiple points of an autonomous system, the monitoring system can estimate, with some accuracy, the health of the autonomous system. In turn, by monitoring at least some of autonomous systems forming a larger internetwork, such as the Internet, the monitoring system can estimate the overall health of at least portions of the internetwork.

Abstract: Aspects of the present disclosure relate to eye tracking systems and methods which track eyes by illuminating the eyes using a light source and detecting the eye illuminations using a sensor. Implementations of the present disclosure may utilize a light source with a dynamic lighting position to account for changes in lighting conditions during the tracking which interfere with detection of the eye illuminations, such as reflections in glasses which may obscure a user's eyes.

Abstract: This disclosure provides systems, methods and apparatus for touch and gesture recognition, using a field sequential color display. The display includes a processor, a lighting system, and an arrangement for spatial light modulation that includes an array of light modulators. Each light modulator is switchable between an open position that permits transmittance of light from the lighting system through a respective aperture and a shut position that blocks light transmission through the respective aperture. The processor switches the light modulators in accordance with a first modulation scheme to render an image and in accordance with a second modulation scheme to selectively pass object illuminating light through at least one of the respective apertures. A light sensor receives light resulting from interaction of the object illuminating with an object and outputs a signal to the processor. The processor recognizes, from the output of the light sensor, a characteristic of the object.
