  • Publication number: 20140314323
    Abstract: Methods and systems of recognizing images may include an apparatus having a hardware module with logic to, for a plurality of vectors in an image, determine a first intermediate computation based on even pixels of an image vector, and determine a second intermediate computation based on odd pixels of an image vector. The logic can also combine the first and second intermediate computations into a Hessian matrix computation.

  • Patent number: 8861847
    Abstract: A system and method for detecting human skin tone in one or more images. The system includes an image processing module configured to receive an image and provide contrast enhancement of the image so as to compensate for background illumination in the image. The image processing module is further configured to detect and identify regions of the contrast-enhanced image containing human skin tone based, at least in part, on the utilization of multiple color spaces and adaptively generated thresholds for each color space. A system and method consistent with the present disclosure is configure to provide accurate detection of human skin tone while accounting for variations in skin appearance due to a variety of factors, including background illumination and objects.

  • Patent number: 8858126
    Abstract: A cutting tool includes a body having a forward end and a rearward end. The forward end includes an insert-receiving pocket with a threaded hole having a center axis. The cutting tool further includes a cutting insert with a countersunk bore with a center axis. The cutting tool includes an error proofing feature for preventing the cutting insert to be properly mounted in an insert-receiving pocket when an offset distance between the center axis of the threaded hole of the insert-receiving pocket and the center axis of the countersunk bore of the cutting insert is greater than a predetermined percentage of the outer diameter of the threaded screw.

  • Publication number: 20140295886
    Abstract: Methods and apparatus relating to geographic content addressing are described. In an embodiment, a server (such as a content server or a content delivery server) transmits content to one or more devices at a first location based on location information corresponding to the first location of the one or more devices. The location information corresponding to the first location of the one or more devices is registered prior to transmission of the content to the one or more devices at the first location (e.g., at a registry server). Other embodiments are also claimed and described.

  • Publication number: 20140258685
    Abstract: A processor may be built with cores that only execute some partial set of the instructions needed to be fully backwards compliant. Thus, in some embodiments power consumption may be reduced by providing partial cores that only execute certain instructions and not other instructions. The instructions not supported may be handled in other, more energy efficient ways, so that, the overall processor, including the partial core, may be fully backwards compliant.

  • Publication number: 20140240326
    Abstract: In an embodiment, a shared memory fabric is configured to receive memory requests from multiple agents, where at least some of the requests have an associated order identifier and a deadline value to indicate a maximum latency prior to completion of the memory request. Responsive to the requests, the fabric is to arbitrate between the requests based at least in part on the deadline values. Other embodiments are described and claimed.

  • Patent number: 8799902
    Abstract: A method and apparatus for throttling power and/or performance of processing elements based on a priority of software entities is herein described. Priority aware power management logic receives priority levels of software entities and modifies operating points of processing elements associated with the software entities accordingly. Therefore, in a power savings mode, processing elements executing low priority applications/tasks are reduced to a lower operating point, i.e. lower voltage, lower frequency, throttled instruction issue, throttled memory accesses, and/or less access to shared resources. In addition, utilization logic potentially trackes utilization of a resource per priority level, which allows the power manager to determine operating points based on the effect of each priority level on each other from the perspective of the resources themselves. Moreover, a software entity itself may assign operating points, which the power manager enforces.

  • Publication number: 20140215240
    Abstract: An apparatus comprises a plurality of cores and a controller coupled to the cores. The controller is to lower an operating point of a first core if a first number based on processor clock cycles per instruction (CPI) associated with a second core is higher than a first threshold. The controller is operable to increase the operating point of the first core if the first number is lower than a second threshold.

  • Publication number: 20140201281
    Abstract: A social network may be established between mobile nodes using a wireless connection. Establishing the social network may be based on an estimated time duration of the wireless connection. In one or more embodiments, establishing the social network may also be based on a similarity of interests among of users of the nodes.
