  • Publication number: 20240069279
    Abstract: A binary photonics lattice that includes a waveguide array having a plurality of single mode waveguides disposed in a substrate, the plurality of single mode waveguides including one or more first waveguides having a first V-number V1 and one or more second waveguides having a second V-number V2. The first V-number V1 is smaller than the second V-number V2. The one or more first and second waveguides are arranged in a linear distribution having first and second edge waveguide regions and a binary waveguide region positioned between the first and second edge waveguide regions. The binary waveguide region is a symmetrical binary representation of a decimal number of two or greater. Further, the binary waveguide region includes at least one first waveguide representing a digit 0 of the symmetrical binary representation and/or at least one second waveguide representing a digit 1 of the symmetrical binary representation.

  • Publication number: 20190102724
    Abstract: Methods, systems, and computer programs are presented for generating custom hiring metrics based on configurable filters to assist in a company's recruiting efforts. One method includes an operation for determining job metrics, for a global pool of users, that are based on job-post communications received by the global pool. The method further includes operations for receiving filters for generating a report, and for identifying a talent pool based on the filters, which are applied to the global pool based on user profile data. A talent-pool metric is determined based on the job-post communications received by the talent pool, and a hiring demand index (HDI) is determined based on the talent-pool metric and the job metrics for the global pool of users, where the HDI provides a degree of difficulty for hiring users from the talent pool. Further, the report including the HDI for the talent pool is presented.

  • Patent number: 9427285
    Abstract: Systems, methods and devices for creating an effect using microwave energy to specified tissue are disclosed. A system for the application of microwave energy to a tissue includes a signal generator adapted to generate a microwave signal having predetermined characteristics, an applicator connected to the generator and adapted to apply microwave energy to tissue. The applicator includes one or more microwave antennas and a tissue interface, a vacuum source connected to the tissue interface, a cooling source connected to the tissue interface, and a controller adapted to control the signal generator, the vacuum source, and the coolant source. The tissue includes a first layer and a second layer, the second layer below the first layer. The controller is configured so that the system delivers energy such that a peak power loss density profile is created in the second layer.

  • Patent number: 8852181
    Abstract: Methods and apparatus for treatment of anatomic defects in human tissues, such as patent foramen ovale (PFO), atrial or ventricular septal defects, left atrial appendage, patent ductus arteriosis, blood vessel wall defects and certain electrophysiological defects, involve positioning a distal end of an elongate catheter device at the site of the anatomic defect, engaging tissues at the site of the anatomic defect to bring the tissues together, and applying energy to the tissues with the catheter device to substantially close the anatomic defect acutely. Apparatus generally includes an elongate catheter having a proximal end and a distal end, a vacuum application member coupled with the distal end for engaging tissues at the site of the anatomic defect and applying vacuum to the tissues to bring them together, and at least one energy transmission member coupled with the vacuum application member for applying energy to tissues at the site of the anatomic defect to substantially close the defect acutely.

  • Patent number: 8465485
    Abstract: Methods, devices and systems for treating patent foramen ovale (PFO) involve advancing a catheter device to a position in a heart for treating a PFO, bringing tissues adjacent the PFO at least partially together, and applying energy to the tissues to substantially close the PFO acutely. Catheter devices generally include an elongate catheter body, at least one tissue apposition member at or near the distal end for bringing the tissues together, and at least one energy transmission member at or near the distal end for applying energy to the tissues. In some embodiments, the tissue apposition member(s) also act as the energy transmission member(s). Applied energy may be monopolar or bipolar radiofrequency energy or any other suitable energy, such as laser, microwave, ultrasound, resistive heating or the like.

  • Publication number: 20120109125
    Abstract: Methods for treating anatomic tissue defects such as a patent foramen ovale generally involve positioning a distal end of a catheter device at the site of the defect, exposing a housing and energy transmission member from the distal end of the catheter, engaging the housing with tissues at the site of the defect, applying suction or other approximating tool to the tissue via the housing to bring the tissue together, and applying energy to the tissue with the energy transmission member or to deliver a clip or fixation device to substantially close the defect. Apparatus generally include a catheter body, a housing extending from a distal end of the catheter body for engaging tissue at the site of the defect, and further adapted to house a fusing or fixation device such as an energy transmission member adjacent a distal end of the housing, or a clip or fixation delivery element.
