    摘要： A micro-fluidic device and methods for measuring one or more rheologic properties of a fluid. The micro-fluidic device includes a substrate and at least one cover bonded to a surface of the substrate with a fluid channel formed in at least one of the cover or the substrate. Further, the micro-fluidic device includes a first differential pressure gauge that can have a first differential pressure sensor in fluid communication with both a first pressure site and a second pressure site. Further still, the micro-fluidic device includes the first pressure site and the second pressure site that can be spaced apart by a first section of the fluid channel. Also, the micro-fluidic device includes a data processor communicatively coupled to the first differential pressure sensor, so as to receive data generated by the first differential pressure sensor.

    摘要： A method and an apparatus for nucleating bubbles in an oil-gas mixture, including introducing a sample comprising an oil-gas mixture into a chamber; and heating the sample with a heater until at least one bubble is thermally nucleated in the chamber. The bubble point (BP) pressure of the sample can be determined by detecting pressure at two points in a system, which includes the chamber and the heater, and by determining the behavior of the nucleated bubble as the pressure on the bubble is varied.

    摘要： A system for transferring data packets between a data packet transfer core and a number of clients of an application layer, including an interface between the data packet transfer core and the application layer for transferring data packets from the packet transfer core to a first client and a second client. The data packet transfer core includes a number of core buffers for receiving data packet transfers input to the data packet transfer core. Each of the number of core buffers include a cut-through data path including a register and a bypass data path, the bypass data path transferring data packets from an input to the register to an output of the register without passing through the register. The system further includes a first data path from the first interface to the first client and a second data path from the interface to the second client, the second data path including an application layer buffer having an input coupled to the interface and an output coupled to the second client, the application layer buffer being for storing data packets transmitted to the second client when data packets are transmitted to the second client at a rate that is faster than the second client is able to receive the data packets. In a first mode of operation, data packets transmitted from the data packet transfer core to the first client are transferred through the bypass data path of at least one of the number of core buffers, over the interface and directly to the first client over the first data path.

    摘要： A system for transferring packets between a packet transfer core and an application layer device over an application layer interface includes a buffer system disposed in the packet transfer core having an input for receiving packets from a packet source; an output for transferring packets to the application layer interface; a buffer device having an input coupled to the input of the buffer system and an output; a selection device having a first input coupled to the output of the buffer device, a control input and an output coupled to the output of the buffer system; and a bypass path coupled between the input of the buffer system and a second input of the selection device. The control input of the selection device receives a first wait signal from the application layer device which is not asserted in a first mode of operation and asserted in a second mode of operation. In the first mode of operation, packets are transferred from the input of the buffer system to the output of the buffer system via the bypass path and, in the second mode of operation, packets are transferred from the input of the buffer system to the buffer device, and are store in the buffer device without being transferred to the output of the buffer system until the first wait signal from the application layer device is deasserted.
