20140075167 | BRANCH HISTORY CACHE AND METHOD - A branch history table cache is a write cache that stores values of branch history counters written to a branch history table. An update to a branch history table counter is reflected in both the branch history table cache and the branch history table. Before a branch history table counter is updated, a check is made to see if the branch history table counter is in the cache. If not, the branch history table counter is updated based on a value of the branch history table counter that was saved during fetch of the branch history table counter. If, however, the branch history table counter value is in the cache, the value in the cache is used to update the branch history table counter. All branches that use the branch history table counter update the correct counter value, improving processor performance by providing more accurate predictions of branches taken. | 03-13-2014 |

20090113181 | Method and Apparatus for Executing Instructions - A method and apparatus for executing instructions in a processor are provided. In one embodiment of the invention, the method includes receiving a plurality of instructions. The plurality of instructions includes first instructions in a first thread and second instructions in a second thread. The method further includes forming a common issue group including an instruction of a first instruction type and an instruction of a second instruction type. The method also includes issuing the common issue group to a first execution unit and a second execution unit. The instruction of the first instruction type is issued to the first execution unit and the instruction of the second instruction type is issued to the second execution unit. | 04-30-2009 |

20120154153 | VIBRATORY FEEDBACK SYSTEMS AND METHODS - Vibratory feedback systems and methods are disclosed. A vibratory feedback system includes a shoe adapted to be secured to a user's foot, a plurality of force sensors and vibration actuators mounted on the shoe, and a microprocessor affixed to the shoe. The force sensors are configured to sense forces exerted by the user's foot. The vibration actuators are configured to provide vibrations to the user's foot. The microprocessor is coupled to receive data from the plurality of force sensors, and is programmed to actuate the plurality of vibration actuators to provide a first characteristic vibration to the user's foot based on the sensed forces. A method of improving the gait of a user includes enabling the user to ambulate with the vibratory feedback system secured to the user's foot, and providing a first characteristic vibration to the user's foot based on the sensed forces using the vibratory feedback system. | 06-21-2012 |

20150230404 | DEVICE FOR COLLECTING AND RELEASING DEBRIS - A device comprises a collection bin and a stationary front plate pivotably coupled with the bin via a hinge mechanism. The bin is rotatable relative to the front plate between a first position, wherein the bin's front end is closed by the front plate, and a second position, wherein the front end is spaced from the front plate for releasing debris out of the bin. An actuator is operatively connected to the hinge mechanism, which includes a bar interconnected between the bin and front plate. The bar is attached to the front plate and the bin. Actuator actuation rotates the bar and the bin in an arcuate motion from the first to the second position, and retraction of the actuator returns the bar and bin to the first position. Rotation of the bin defines a center of rotation on the opposite side of the front plate from the bin. | 08-20-2015 |

20130237387 | Controlled Pressure Resistance Unit Engagement System - A controlled pressure resistance unit engagement system for bicycle training devices uses a clutch arrangement to limit the maximum torque applied. By doing so, a consistent, correct pressure on a bicycle tire by the resistance unit is achieved, thereby avoiding damage to the resistance unit and the bicycle tire and allowing a more consistent resistance unit power curve to be achieved. | 09-12-2013 |

20140064920 | SYSTEM AND METHOD TO IMPROVE PERFORMANCE OF A COMPRESSOR DEVICE COMPRISING VARIABLE DIFFUSER VANES - Embodiments of a system and method can modify the position of diffuser vanes to improve performance of a compressor device, e.g., a centrifugal compressor. These embodiments form a feedback loop to manage the position of the diffuser vanes relative to one or more operating parameters on the compressor device. In one embodiment, the system and method measure input power with the diffuser vanes at a first position and a second position. Changes in the input power will identify other positions for the diffuser vanes that optimize performance of the compressor device, e.g., to reduce power consumption and to achieve and maintain peak compressor efficiency within the entire operating envelope of the compressor device. | 03-06-2014 |
20140064948 | SYSTEM AND METHOD FOR OPERATING A COMPRESSOR DEVICE - Embodiments of a system and method manipulate the position of inlet guide vanes and the drive speed for optimizing performance of a compressor device (e.g., a centrifugal compressor). In one embodiment, the systems and methods can correlate setpoints (e.g., inlet volume flow and discharge pressure) desired for installation and/or implementation of the compressor device with reference data collected as part of in-situ performance testing. This reference data identifies, in one embodiment, a position for the inlet guide vanes and a drive speed for a number of different setpoints at a set of reference conditions (e.g., ambient temperature and ambient pressure). | 03-06-2014 |
