  • Patent number: 10338303
    Abstract: Systems and methods for increasing dynamic contrast in a liquid crystal display (LCD) may include a segmented backlight that may include one or more segments and one or more sets of light emitting diodes (LEDs). Each set of LEDs may be configured to illuminate a corresponding segment and each segment may include a notch(es) configured as a light barrier to reduce light leakage to non-adjacent segments. The notch(es) may be of variable length, depth, and width and may be three-dimensional, having a width the varies along the depth and length of the notch and a depth that varies along the width and length of the notch. In some embodiments, the notch(es) may be reflective, some degree of opaque, and/or blackened.

  • Patent number: 10299923
    Abstract: A method of crimping an implantable prosthetic valve can include placing protective material over at least a portion of the implantable prosthetic valve. The protective material can be configured to occupy space between open cells of a frame of the implantable prosthetic valve to prevent damage to a leaflet structure of the implantable prosthetic valve. The method can also include crimping the implantable prosthetic valve with the protective material on the implantable prosthetic valve, and removing the protective material from between the frame and the leaflet structure of the implantable prosthetic valve.

  • Patent number: 10256171
    Abstract: Embodiments are directed to a method of forming a semiconductor device and resulting structures having an air spacer between a gate and a contact by forming a gate on a substrate and over a channel region of a semiconductor fin. A contact is formed on a doped region of the substrate such that a space between the contact and the gate defines a trench. A first dielectric layer is formed over the gate and the contact such that the first dielectric layer partially fills the trench. A second dielectric layer is formed over the first dielectric layer such that an air spacer forms in the trench between the gate and the contact.

  • Publication number: 20190094586
    Abstract: Techniques are disclosed relating to the transmission of data based on a polarization of a light signal. In some embodiments, data may include 3D video data for viewing by a user. Systems for transmitting data may include a display device and a device for switching the polarization of a video source. Systems for receiving data may include eyewear configured to present images with orthogonal polarization to each eye. In some embodiments, the rate of switching of the polarization switcher may introduce a distortion to the optical data. A Pi-cell device may be used in some embodiments to reduce distortion based on switching speed. In some embodiments, polarization switchers may introduce a distortion based on the frequency of transmitted light. In some embodiments, optical elements including in the transmitting or receiving devices may be configured to reduce distortions based on frequency.

  • Publication number: 20190008505
    Abstract: Disclosed herein are devices and methods for assessing the surface of a target cardiac tissue and for delivering a tissue anchor to cardiac tissue at a preselected depth within the myocardium in a beating heart procedure. In one variation, an anchor delivery device comprises an elongate body, a tissue anchor disposed within a first longitudinal lumen of the elongate body, and a tissue depth indicator slidable within a second longitudinal lumen of the elongate body. The tissue depth indicator has a first configuration that indicates the boundary of the surface of the target tissue and a second configuration that indicates when the distal tip of the elongate body has been advanced to a preselected depth into the target tissue. In some variations, a tissue depth indicator may also be configured to resist or limit the penetration of the delivery device into tissue after a preselected depth has been reached.

  • Publication number: 20180153553
    Abstract: Described herein are devices and methods for delivering implants that include multiple coupled anchors. The anchors are secured to tissue using a multi-opening guide tunnel that is configured to releasably retain one or more portions of the implant located between two of the anchors. The releasable retention of one or more intervening portions of the implant maintains the position of the implant and the guide tunnel until the implant is secured to the tissue. The multi-opening guide tunnel permits securement of the multiple anchors without requiring repositioning of the guide tunnel for each anchor.
