    摘要： An obstruction removal system for percutaneous removal of clots or obstructions within the vascular system is disclosed. The obstruction removal system includes a multi-lumen catheter with a plurality of circulating capture devices attached to or integral with a drive belt. The circulating capture or interference devices affect removal of the clot or obstruction bit-by-bit through a series of passes. The obstruction removal system may include one or more drive mechanisms, such as a pulley system and/or a vacuum source and/or a pressurization source, on its proximal end for driving the drive belt and capture devices through the catheter in a circulating manner. The obstruction removal system may also include one or more cleaning mechanisms, such as a vacuum chamber and/or a fluid rinse chamber, for removing the captured clot pieces from the capture devices.

    摘要： An invention for coherent array image formation and restoration is taught. The invention is applicable for both 2D and 3D imaging using either 1D or 2D arrays, respectively. A transducer array is subdivided into subarrays, each subarray having a number of adjacent array elements. All elements of each subarray transmit and receive in parallel. The signals received from each subarray are delayed and summed to form scan lines, or beams. The low-beam-rate beams formed from each subarray are upsampled and interpolated prior to forming high-beam-rate images. Depending on the subarray geometry, a subarray-dependent restoration filter is also applied to the subarray beams. The restored beams from each subarray are combined to form the final high-beam-rate image. The invention significantly reduces the front-end hardware complexity compared to conventional methods such as full phased array imaging with comparable image quality.

    摘要： A flexible exhaust stack is suitable for use with a vehicle for which relative motion occurs between the cab of the vehicle and exhaust system components mounted to the vehicle frame. The exhaust stack includes a pipe mounted to the cab and having inlet and discharge ends. A collar is secured to an interior portion of the pipe between the inlet end and the discharge end. A flexible hose is at least partially disposed within the pipe, with a discharge end secured to the collar and an inlet end in fluid communication with the frame-mounted exhaust system components. The exhaust stack receives exhaust gases from the frame-mounted exhaust system components and discharges the exhaust gases from the discharge end of the pipe, while the flexible hose allows for relative motion between the cab and the exhaust system.
