An expandable member for characterizing a three-dimensional space within a mammalian body is described. The expandable member is delivered to a target region in a deflated state where it is expanded by inflation of the member. Sensory transducers that contact the member relay sensory information generated when the member is in an expanded state to a microprocessor located outside the body. Using the sensory information, a data-driven picture that characterizes the three-dimensional space within the body is created with a microprocessor. The apparatus is useful in preparation for minimally invasive surgical therapy.

A network analyzer includes a sampler and a network anomaly detector. The sampler acquires communication data flowing through nodes by a data collector, estimates a topology of the nodes based on the acquired communication data by a topology estimator, stores the estimated topology of the nodes in a storage, reads out the estimated result from the storage to generate a predetermined item for each read-out topology of the nodes as a sampling rule by a rule generator, and samples the supplied communication data based on the generated sampling rule by a packet sampler. The topology of the network is thereby estimated in advance to narrow down objects to be sampled. The behavior of the communication data can thus be grasped in correlation between a target network and other networks.

Systems and methods are disclosed for improving the resolution and quality of an image formed by signals from an array of receivers. Multiple receivers introduce variations in arrival times that can be less than the period of an operating signal, and also less than the period associated with a sampling operation. Thus, multiple receivers allow sampling of fine features of reflected signals that would be considered beyond the resolution associated with the operating signal. Use of multiple receivers also provides an effective sampling rate that is greater than the sampling rate of an individual receiver. Similar advantages can be obtained using multiple transmitters. Such advantageous features can be used to obtain high resolution images of objects in a medium in applications such as ultrasound imaging. Sub-Nyquist sampling is discussed.

A receiver, system and method for providing symbol timing recovery that allows for inexpensive and low-complexity synchronization for communication systems.

The receiver further controls a sampling device such that the in-phase (I) and quadrature (Q) components are sampled at an optimum sample rate and at an optimum instance of time without requiring a numerically controlled oscillator or voltage controlled oscillator.
