    摘要： Image sensors and color filter arrays for in-pixel charge summing and interlaced readout modes may be provided. An image sensor that supports charge summing and interlaced readout modes may include an array of pixels with pairs of adjacent green, red, and blue light-sensitive pixels. An image sensor may implement an in-pixel charge summing readout mode in which charges from pairs of pixels are summed onto a common node and then read out from the common node. An image sensor may implement an interlaced readout mode in which image data is read out from alternating rows of the image sensor. An image sensor may use a shared readout scheme in which a group of four pixels is formed from two pairs of commonly-colored pixels. The four pixels may share circuitry such as a reset transistor, a buffer transistor, and a row select transistor and may connect to a single readout line.

    摘要： Electronic devices may include camera modules. A camera module may include an array camera having an array of lenses and an array of corresponding image sensors. Parallax correction and depth mapping methods may be provided for array cameras. A parallax correction method may include a global and a local parallax correction. A global parallax correction may be determined based on one-dimensional horizontal and vertical projections of edge images. Local parallax corrections may be determined using a block matching procedure. Further improvements to local parallax corrections may be generated using a relative block color saturation test, a smoothing of parallax correction vectors and, if desired, using a cross-check between parallax correction vectors determined for multiple image sensors. Three dimensional depth maps may be generated based on parallax correction vectors.

    摘要： An elongated flexible medical device is inserted into a patient's body via a natural orifice, and advanced through the natural orifice to a location proximate innervated tissue that influences renal sympathetic nerve activity. The medical device can be advanced into a body organ and to a location within the organ proximate the innervated tissue. The organ may comprise an organ of the gastrointestinal tract or urinary tract. The medical device may be advanced through and beyond an access hole in a wall of the organ, and situated at a location proximate the innervated tissue. One or both of imaging and ablation energy is delivered from a distal end of the medical device to the innervated tissue. Innervated renal tissue can be ablated using various forms of energy, including RF energy, ultrasound energy, optical energy, and thermal energy.

    摘要： A catheter is configured to access a renal artery. A lumen of the catheter's shaft is dimensioned to receive a flexible actuation member which extends between the shaft's proximal and distal ends. The actuation member is moveable within the lumen and subject to elastic deformation, friction, and/or whip along its length. A flexible support member is coupled to a distal end of the actuation member and extendible beyond a distal tip of the shaft. An RF ablation electrode at a distal end of the support member is configured to ablated perivascular renal nerve tissue. A position converter at the distal end of the shaft is configured to convert movement of the actuation member into one or both of controlled rotational and axial movement of the support member and electrode to one of a multiplicity of stable circumferential positions substantially free of elastic deformation, friction, and/or whip impacting actuation member movement.

    摘要： A catheter comprises a flexible shaft having a length for accessing the renal artery. A balloon arrangement, dimensioned for deployment within the renal artery, is provided at the shaft's distal end and fluidly coupled to a lumen arrangement. A balloon body is configured to complete at least one revolution of the shaft's distal end to form a spiral configuration thereabout, and is secured to the shaft by one or more movable mounting arrangements. The balloon body supports an electrode arrangement for ablating perivascular renal nerves in a substantially spiral pattern. A cooling arrangement cools at least the electrode contact regions during ablation. The distal end of the shaft has a stiffness sufficient to oppose a force produced by the balloon body when inflated that tends to contort the shaft's distal end and to maintain a substantially constant apposition force between the electrodes and an inner wall of the renal artery.
