Abstract: Self-discovering transaction accelerators improve communications between a client and a server. A client directs a message to a server. A client-side transaction accelerator intercepts the message, terminates the connection with the client, and accelerates the request by replacing segments of data with references. The accelerated request is forwarded to a server-side transaction accelerator through a new connection. The server-side transaction accelerator reconstructs the message by replacing the reference with segment data in a persistent segment store accessible to the server-side transaction accelerator. The reconstructed request is then provided to the server. Accelerations may occur in any direction of communication. Persistent segment stores can be pre-populated with segment data from other transaction accelerators and anticipated transactions. The persistent segment store can store segments that are data segmented based on content of the data and can be independent of transaction protocol, application, and device.

Abstract: A method and apparatus for quantifying and displaying ultrasound signals in an ultrasonic system are provided. A first signal value for each of at least one spatial location in a region of interest is acquired at a first time, and the signal values are summed to obtain a first surface integral value. A second signal value for each of said at least one spatial location in said region of interest is acquired at a second time, and the second signal values are summed to obtain a second surface integral value. The first surface integral value is summed with the second surface integral value to obtain a time based integral. The time based integral is displayed. Other quantities based on any of various ultrasound parameters, such as Doppler energy, Doppler velocity and B-mode intensity, are calculated and displayed as quantities or as waveforms as a function of time. Furthermore, various comparisons of quantities and waveforms are provided. Image plane data or other ultrasound data are used in the calculations. Finally, a histogram data structure is provided to aid calculation of the various quantities.
