International Classification:

US Classification:

710105, 710 52, 710310

Abstract:

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.

US Classification:

Abstract:

A system for controlling packet transfers includes a packet transfer core; an application layer coupled to the packet transfer core by an application interface; a buffer in the packet transfer core for receiving packets from a packet source and transferring the packets to the application layer over the application interface, the packets comprising one or more words; a register in the application layer for receiving packets from the application interface; and a client device for receiving packets transferred thereto from the register. When the client is unable to receive packets from the register, the client asserts a first wait signal to the register, causing the register to continue receiving packets from the interface and storing the packets without transferring the packets to the client. When the register is unable to continue receiving packets from the interface, the register asserts a second wait signal to the buffer over the application interface, causing the buffer to continue receiving packets from the packet source and storing the packets without transferring packets to the interface.

International Classification:

G06F 3/00

US Classification:

710 52, 710105, 710310

Abstract:

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.

US Classification:

73 5441, 73 5402, 73 5424, 73 5425

Abstract:

A method and apparatus for providing, e. g. , identifying or determining, at least one parameter of a fluid moving through a fluid channel using a vibrating wire in contact with the fluid moving through the fluid channel that is clamped under tension. The vibrating wire is actuated by an actuating device capable of displacing the vibrating wire from an initial position. An interpretation element further is utilized to provide a parameter of the fluid moving through the fluid channel based upon data from the vibrating wire following actuation by the actuation element.

Abstract:

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.

Abstract:

A fluid separation method for performing fluid analysis of an unfiltered fluid. The fluid separation method includes providing a structure with a fluid analyzer and a power supply. Using a substrate for receiving a fluid flow stream of a multiphase mixture through a fluid sample inlet, wherein the substrate interconnects with the structure. Providing a membrane disposed across the fluid sample inlet for separating a fluid of interest from the multiphase mixture, wherein the fluid flow stream of the multiphase mixture has a shear rate that prevents a fouling of the membrane. Finally, the fluid separation method includes the substrate having fabricated channels, such that the fabricated channels are arranged substantially tangent to the fluid stream downstream of the porous membrane.

US Classification:

7315223

Abstract:

A gas separation and detection tool for performing in situ analysis of borehole fluid is described. The tool operates by introducing a reagent to a test sample and causing the resulting mixture to flow through a microfluidic channel where optical testing is performed. The optical testing detects a change in a characteristic of the reagent in response to expose to one or more particular substances in the test sample. The test sample may be borehole fluid, a mixture of borehole fluid and scrubbing fluid subsequently mixed with reagent, a mixture of reagent and gas separated from borehole fluid, or a mixture of scrubbing fluid and gas separated from borehole fluid which is subsequently mixed with reagent. A membrane may be employed to separate one or more target gasses from the borehole fluid.
