  • Patent number: 8522564
    Abstract: A temperature control system includes a compressor, a condenser, an evaporator, a receiver, and an accumulator. A valve is positioned between the evaporator and the receiver. An evacuation line has a first end in fluid communication with heat transfer fluid between the valve and the receiver, and a second end in fluid communication with the accumulator. The evacuation line provides for flow of the heat transfer fluid from both of the first heat exchanger and the receiver to the accumulator during an evacuation mode of operation of the temperature control system. The valve can take the form of a check valve or an expansion valve without a bleed port.

  • Patent number: 8526718
    Abstract: A mobile device comprising a camera and color detection software stored in memory of the mobile device, wherein the color detection application analyzes and displays component colors in a captured image and compares component colors in two such captured images. The color detection application displays component colors in a specific format such as red, green and blue and displays percentage of these colors in each of the compared images. The color detection provides textual and audio feedbacks of the extent of match between colors of the two images. The two captured images that are to be compared are displayed in split windows. A client-application compares a first digital image with a second digital image and describes the closeness of a color of the first digital image to the color of the second digital image.

  • Publication number: 20130226413
    Abstract: A non-contact RFID reader reads a code contained on an RFID tag carried by a driver of a vehicle. The code is assigned to a specific individual expected to operate the vehicle. An electronic module in the vehicle contains a data file uniquely associated with the code, and the data file contains physical characteristics of the driver that may be pertinent to proper functioning of safety systems of the vehicle, such as weight, height, age, and sex. Performance parameters of restraints and/or other safety systems, such as an airbag associated with the driver's seating position are adapted in accordance with the physical characteristics in the data file. The RFID reader may read multiple tags on board the vehicle, so that restraints for multiple seating positions in addition to the driver's seat may be adapted to the individual occupying those positions.

  • Patent number: 8521705
    Abstract: Mechanisms are provided for accelerated data deduplication. A data stream is received an input interface and maintained in memory. Chunk boundaries are detected and chunk fingerprints are calculated using a deduplication accelerator while a processor maintains a state machine. A deduplication dictionary is accessed using a chunk fingerprint to determine if the associated data chunk has previously been written to persistent memory. If the data chunk has previously been written, reference counts may be updated but the data chunk need not be stored again. Otherwise, datastore suitcases, filemaps, and the deduplication dictionary may be updated to reflect storage of the data chunk. Direct memory access (DMA) addresses are provided to directly transfer a chunk to an output interface as needed.

  • Patent number: 8522251
    Abstract: Task placement is influenced within a multiple processor computer. Tasks are classified as either memory bound or CPU bound by observing certain performance counters over the task execution. During a first pass of task load balance, tasks are balanced across various CPUs to achieve a fairness goal, where tasks are allocated CPU resources in accordance to their established fairness priority value. During a second pass of task load balance, tasks are rebalanced across CPUs to reduce CPU resource contention, such that the rebalance of tasks in the second pass does not violate fairness goals established in the first pass. In one embodiment, the second pass could involve re-balancing memory bound tasks across different cache domains, where CPUs in a cache domain share a same last mile CPU cache such as an L3 cache.
