Abstract: This patent document discloses assemblies and methods for removing obstructive material from a body vessel or other cavity. An assembly can include an elongate inner member, an elongate outer member, an aspirator, one or more valves, or a waste collection reservoir. Each of the elongate members can extend from a proximal end portion to a distal end portion and can include a lumen therethrough.

When the source code compilation is successful, the source code is parsed to define code elements, an integration function is generated, the integration function is compiled with the source code using a second compiler in a second programming language to define an executable, an entry point address to the generated integration function is retrieved from the defined executable, an incremented revision number and the entry point address are stored in a created revision data structure, and the created revision data structure is stored in a created module context data structure. The integration function maps first input and output parameters of the source code in the second programming language to second input and output parameters of the source code in the first programming language.

Abstract: A method is provided for aligning RF signals of a first channel bank and additional channel banks in a test platform. A plurality of correlators is used to correlate a reference code signal carrying a particular code at a particular chip rate with a received code signal carrying the particular code at the particular chip rate from the first channel bank to establish a first timing offset. The plurality of correlators is used to correlate a continuation of the reference code signal with additional received code signals carrying the particular code at the particular chip rate from the additional channel banks to establish additional timing offsets. The first timing offset and additional timing offsets are applied to the first and additional channel banks. The plurality of correlators includes at least 12 correlators, and a timing offset is established in a correlation interval having a shorter duration than the particular code.

Abstract: An automated method is provided for suppressing spurious signals in a direct digital synthesized signal. To determine magnitudes of local oscillator (“LO”) feedthrough and image frequency signal components, a digitally synthesized RF signal is digitally analyzed. To reduce the magnitude of the LO feedthrough signal component, one or more first parameters of at least one digital-to-analog converter is automatically adjusted using a first search pattern. To reduce the magnitude of image frequency signal component, at least one second parameter of the at least one digital-to-analog converter is automatically adjusted and at least one third parameter of a phase compensation network is automatically adjusted using a second search pattern. The automatically adjusting for the LO feedthrough signal component and for the image frequency signal component can be iterated.
