  • Patent number: 10929567
    Abstract: Embodiments of the present invention disclose a method, computer program product, and system for parallel access to an electronic design automation (EDA) application. The computer receives a request to access an electronic design automation (EDA) application from at least two user computing device and authenticates a user associated with each of the requests from the at least two user computing devices to access the EDA application. The computer determines a level of access to be granted to each of the user of the at least two user computing devices and creates a parallel connection to each of the at least user computing device based on the determined level of access granted to each of the users. The computer retrieves data to be transmitted to each of the at least user computing device to be displayed on each of the user computing devices and stores the data in a memory unit.

  • Patent number: 9785735
    Abstract: A system and method perform global routing during integrated circuit fabrication. The method includes performing a design change in a portion of an integrated circuit design using a processor, determining whether the design change requires rerouting, and requesting a global routing lock based on determining that the design change requires the rerouting. The method also includes a router providing control of the global routing lock to one of two or more of the threads that request the global routing lock, and performing global routing for all of the two or more of the threads in parallel. A physical implementation of the integrated circuit design is obtained.

  • Publication number: 20160015411
    Abstract: Rotator cuff tears (complete and partial) are surgically repaired without needing more dermal access than percutaneous punctures. The surgeon is afforded a range of options for where to place a second tunnel in the bone, and selection by the surgeon of a desired bone bridge size is provided in advance of tunnel construction. Also, stitching in rotator cuff surgery can be accomplished without the need for suture anchors or added cost of secondary suture passers. Multiple stitch configurations including X-patterns are possible with combinations of preloaded loops and or sutures passed simultaneously through tissue and bone. Fixation is achieved without the use of suture anchors, buttons or other rigid implants.

  • Patent number: 8955252
    Abstract: An automated gravimetric screening system and method controls soil moisture in a plurality of potted plants to perform water deficit experiments in a greenhouse using a stationary support platform and pot design that maintains the plants in a static location during the testing. By weighing and re-watering the pots from beneath the platform, the present system and method permits an upper gantry to capture high resolution images, temperature data, or other sensor data to quantify the plant stress level or plant canopy characteristics during the experiment.

  • Patent number: 8196237
    Abstract: A movable patient support includes a frame, a patient support surface supported at the frame, a base supporting the frame and having a plurality of bearing assemblies for moving the base along a floor surface. The support also includes a brake, a brake actuator for actuating the brake of at least one bearing assembly, and a brake bar coupled to the brake actuator. The brake bar is movable between a non-braking position and a braking position wherein the actuator causes the brake to move to its braking position. Further, the brake bar extends between the head end and the foot end of the frame and further has a portion extending outwardly from the brake actuator to at least close proximity to the bearing footprint defined by the bearing assemblies but within the frame footprint to thereby provide relatively easy access to the brake bar to an attendant standing adjacent one of the longitudinal sides of the frame.
