  • Publication number: 20170211833
    Abstract: A temperature control method includes obtaining, by a controller, a space temperature value, a space temperature set point, a discharge air temperature value, and a discharge air temperature set point. The method further includes determining a compressor speed using a first PI loop based on the space temperature set point and the space temperature value, and determining a supply fan speed using a second PI loop based on the discharge air temperature set point and the discharge air temperature value. The temperature control method further includes outputting a first control signal that controls the speed of a variable speed compressor based on the determination of whether the compressor speed is within the compressor operation range and a second control signal to control the speed of a variable speed supply fan based on the determination of whether the supply fan speed is within the supply fan operation range.

  • Patent number: 9635113
    Abstract: The software-as-a-service (the “Service”) is a web-based software product available to a service professional (an “SP”) allowing such SP to digitally engage clients on matters using any device that can connect to the internet such as a laptop, smartphone, tablet or other web-enabled devices (Google glasses, web-enabled watches etc.) (the “Device”). SPs can also use the Service to collaborate with their clients on matters by communicating and sharing documents with them in private collaboration portals exclusive to a specific client matter which are accessible through the Service and created by the Service during the Service's digital engagement process. The Service is presently directed to SPs such as lawyers for use in the digital engagement of, and collaboration with, their clients on client matters.

  • Publication number: 20160162402
    Abstract: In one embodiment of the present invention, a convolution engine configures a parallel processing pipeline to perform multi-convolution operations. More specifically, the convolution engine configures the parallel processing pipeline to independently generate and process individual image tiles. In operation, for each image tile, the pipeline calculates source locations included in an input image batch based on one or more start addresses and one or more offsets. Subsequently, the pipeline copies data from the source locations to the image tile. The pipeline then performs matrix multiplication operations between the image tile and a filter tile to generate a contribution of the image tile to an output matrix. To optimize the amount of memory used, the pipeline creates each image tile in shared memory as needed. Further, to optimize the throughput of the matrix multiplication operations, the values of the offsets are precomputed by a convolution preprocessor.
