  • Patent number: 8811173
    Abstract: In one embodiment, a plurality of queues are established corresponding to each of a plurality mobiles, respectively. Data packets associated with the plurality of mobiles are received at a network element. Each received data packet is assigned to a corresponding one of the plurality of queues. A determination operation is performed on a selected one of the plurality of queues to determine whether or not to send one or more packets of each queue from the network gateway element. The determination operation is performed based on a comparison between a packet size of a head packet and an adaptive transmission threshold value associated with the selected queue. The adaptive transmission threshold value is a value that is changed based on an amount data sent from the selected queue. The head data packet being an earliest received data packet in the selected queue.

  • Patent number: 7472550
    Abstract: A turbine engine system and a method for using the turbine engine system that includes at least one low-pressure compressor, at least one high-pressure compressor, at least one low-pressure turbine, and at least one high-pressure turbine. In addition, the turbine engine system includes an absorption refrigeration system that is used to pre-cool an air-gas mixture before it enters the high-pressure compressor. As such, the pre-cooled mixture is easier to compress, thereby increasing the thermal efficiency of the turbine engine. Additionally, the exhaust heat from the air-gas mixture that is pre-cooled may be used to drive the absorption refrigeration system. Lastly, water, may be extracted from the evaporator of the absorption refrigeration cycle.

  • Publication number: 20050088745
    Abstract: An imaging system for imaging an object onto an image plane. An optical arrangement forms an intermediate image of the object at an intermediate plane with a first value of axial resolution. The imaging system also includes a digital processor configured to process the intermediate image to form a final image of the object at the image plane. The imaging system further includes a specially designed optical element that cooperates with the optical arrangement and the digital processor to define a second value of axial resolution that is greater than the first value.
