A catalyst structure includes: (1) a substrate; (2) a catalyst layer on the substrate; and (3) an adhesion layer disposed between the substrate and the catalyst layer. In some implementations, an average thickness of the adhesion layer is about 1 nm or less. In some implementations, a material of the catalyst layer at least partially extends into a region of the adhesion layer. In some implementations, the catalyst layer is characterized by a lattice strain imparted by the adhesion layer.

A manufacturing process includes: depositing a first catalyst on a first gas diffusion layer (GDL) to form a first catalyst-coated GDL; depositing a first ionomer on the first catalyst-coated GDL to form a first gas diffusion electrode (GDE); depositing a second catalyst on a second GDL to form a second catalyst-coated GDL; depositing a second ionomer on the second catalyst-coated GDL to form a second GDE; and laminating the first GDE with the second GDE and with an electrolyte membrane disposed between the first GDE and the second GDE to form a membrane electrode assembly (MEA). A MEA includes a first GDL; a second GDL; an electrolyte membrane disposed between the first GDL and the second GDL; a first catalyst layer disposed between the first GDL and the electrolyte membrane; and a second catalyst layer disposed between the second GDL and the electrolyte membrane, wherein a thickness of the electrolyte membrane is about 15 &#x3bc;m or less.

A real-time signal processing technique for ultrasonic imaging of tissue vibrations for localizing the source of a bruit in a 2D image with respect to the anatomy and/or for obtaining simultaneous information about vibrations and the underlying blood flow. The bruit can be quantitatively assessed using an ensemble of ultrasound echoes. Signal processing enables estimation of wall displacement and the display of time-resolved vibration spectrum. Vibrations are detected and color-coded according to their amplitude and frequency and overlaid on the B-mode and/or color-flow image in real time. Proposed vibration imaging algorithms use data acquired during conventional ultrasonic color-flow imaging and the clutter signal, normally suppressed in color-flow imaging, to detect and characterize tissue vibrations. Three vibration imaging algorithms based on parametric modeling of vibrations and other criteria distinguish between clutter, blood flow, and vibrations. The techniques are usable to detect, locate, image, and quantitatively grade stenoses in blood vessels.

An in vivo source of compression is used to cause a bodily structure of interest to expand and contract. Ultrasound signals are incident and their echoes are processed by a strain processor. Resulting strain images are freed from noise caused by external sources of compression. A tissue stiffness index is calculated to obtain quantitative measure of stiffness.

Ultrasonic estimation of strain induced by in vivo compression

A medical device is configured to diagnose whether a nodule of a bodily organ is malignant or benign using ultrasound elastography to determine a nodule stiffness index. Using either an external compression source or an in vivo pulsation source, the stiffness of the nodule of the bodily organ can be quantified by either its static properties or dynamic properties. The nodule can be classified as Type I, which is benign requiring further observation, or Type II, which is malignant requiring invasive procedures.

Nodule screening using ultrasound elastography

Strain is directly estimated in ultrasound elasticity imaging without computing displacement or resorting to spectral analysis. Conventional ultrasound elasticity imaging relies on calculating displacement and strain is computed from a derivative of the displacement. However, for typical parameter values used in ultrasound elasticity imaging, the displacement can be as large as a hundred times or displacement differences. If a tiny error in the calculation of displacement occurs, this could drastically affect the calculation of strain. By directly estimating strain, image quality is enhanced and the reduction in computational effort facilitates commercialization to aid in diagnosing disease or cancerous conditions.

Ultrasonic direct strain estimation using temporal and spatial correlation

An ultrasound based technique for detecting and imaging vibrations in tissue caused by eddies produced during bleeding through punctured arteries or from organs. A clutter signal, normally suppressed in conventional color flow imaging, is employed to detect and characterize local tissue vibrations, to detect internal bleeding in an image, or as an audible or palpable signal, or a readout. Using a tissue vibration image, the origin and extent of vibrations relative to the underlying anatomy and blood flow can be visualized in real time, enabling measurements of vibration amplitude, frequency, and spatial distribution. Bleeding rate can be determined from the frequency and amplitude of the vibrations. Signal processing algorithms usable to identify tissue vibrations from an ensemble of 2D ultrasound data include those based on phase decomposition, spectral estimation using eigendecomposition, and spectral estimation using autoregressive modeling for isolating vibrations from clutter, blood flow, and noise.

A deep-pipeline system substantially reduces the overhead of setup delays and pipeline delays by dynamically controlling access of a plurality of configuration register sets by both a host central processing unit (CPU) and the stages of the pipelines. A master configuration register set is loaded with configuration parameters by the host CPU in response to an index count provided by a setup-index counter. A plurality of other counters are employed to track timing events in the system. In one embodiment, a run-index counter provides a run-index count to the first stage of the pipeline that is propagated along the stages, enabling configuration register sets to transfer configuration parameters to the stages of the pipeline when required to enable processing of a task. In an alternative embodiment, a plurality of D flip-flops sequentially propagates a state for successive registers, so that the setup-index counter is not required.

A VLIW instruction format is introduced having a set of control bits which identify subinstruction sharing conditions. At compilation the VLIW instruction is analyzed to identify subinstruction sharing opportunities. Such opportunities are encoded in the control bits of the instruction. Before the instruction is moved into the instruction cache, the instruction is compressed into the new format to delete select redundant occurrences of a subinstruction. Specifically, where a subinstruction is to be shared by corresponding functional processing units of respective clusters, the subinstruction need only appear in the instruction once. The redundant appearance is deleted. The control bits are decoded at instruction parsing time to route a shared subinstruction to the associated functional processing units.
