Publication number: 20230129708Abstract: Procedure training apparatus, methods and systems which in one embodiment allow surgical trainees to receive expert clinical guidance during live surgery or to practice surgical skills on anatomical models in a realistic manner with an augmented reality headset which is in audio and visual communication with a remotely located trainer having a similar AR headset. A unique feature of the system includes providing live or static imaging of the surgical site to the AR headsets of the trainee and trainer wherein the imaging is provided from medical or other devices (e.g., ultrasound) through a device(s) media hub. The images are displayed in the field of view of the surgeon so that they may see their hands, the patient (or model) and the imaging simultaneously. Controls allow the imaging on the respective AR headsets to be switched on command typically by the trainer which allows the trainer to deliver the trainer's surgical site image (e.g.Type: ApplicationFiled: October 24, 2022Publication date: April 27, 2023Inventors: Nelson Stone, Steven Griffith, Jonathan Stone

Patent number: 11519098Abstract: Silicon carbide (SiC) wafers, SiC boules, and related methods are disclosed that provide improved dislocation distributions. SiC boules are provided that demonstrate reduced dislocation densities and improved dislocation uniformity across longer boule lengths. Corresponding SiC wafers include reduced total dislocation density (TDD) values and improved TDD radial uniformity. Growth conditions for SiC crystalline materials include providing source materials in oversaturated quantities where amounts of the source materials present during growth are significantly higher than what would typically be required. Such SiC crystalline materials and related methods are suitable for providing large diameter SiC boules and corresponding SiC wafers with improved crystalline quality.Type: GrantFiled: January 29, 2020Date of Patent: December 6, 2022Assignee: Wolfspeed, Inc.Inventors: Yuri Khlebnikov, Robert T.

Publication number: 20220189768Abstract: Silicon carbide (SiC) materials including SiC wafers and SiC boules and related methods are disclosed that provide large dimension SiC wafers with reduced crystallographic stress. Growth conditions for SiC materials include maintaining a generally convex growth surface of SiC crystals, adjusting differences in front-side to back-side thermal profiles of growing SiC crystals, supplying sufficient source flux to allow commercially viable growth rates for SiC crystals, and reducing the inclusion of contaminants or non-SiC particles in SiC source materials and corresponding SiC crystals. By forming larger dimension SiC crystals that exhibit lower crystallographic stress, overall dislocation densities that are associated with missing or additional planes of atoms may be reduced, thereby improving crystal quality and usable SiC crystal growth heights.Type: ApplicationFiled: December 15, 2020Publication date: June 16, 2022Inventors: Yuri Khlebnikov, Varad R.

Publication number: 20210198804Abstract: Silicon carbide (SiC) wafers and related methods are disclosed that include large diameter SiC wafers with wafer shape characteristics suitable for semiconductor manufacturing. Large diameter SiC wafers are disclosed that have reduced deformation related to stress and strain effects associated with forming such SiC wafers. As described herein, wafer shape and flatness characteristics may be improved by reducing crystallographic stress profiles during growth of SiC crystal boules or ingots. Wafer shape and flatness characteristics may also be improved after individual SiC wafers have been separated from corresponding SiC crystal boules. In this regard, SiC wafers and related methods are disclosed that include large diameter SiC wafers with suitable crystal quality and wafer shape characteristics including low values for wafer bow, warp, and thickness variation.Type: ApplicationFiled: December 17, 2020Publication date: July 1, 2021Inventors: Yuri Khlebnikov, Varad R.

Publication number: 20200069884Abstract: An automatic injection device including a housing, a chamber with a first compartment and a second compartment, and a seal structure between the compartments. The seal structure is initially in a sealing condition that seals the first compartment from the second compartment, where the seal includes a plug and an outer sealing member. The plug is slidably movable within the outer sealing member to convert the seal structure from the sealing condition to a mixing condition by opening a path between the first compartment and the second compartment. The automatic injection device also includes a needle assembly and an activation assembly. Activation of the activation assembly causes (1) pressurization of the first compartment, (2) the seal structure to convert from the sealing condition to the mixing condition, and (3) the first and second medicament components to be mixed and forced through the needle assembly.Type: ApplicationFiled: November 4, 2019Publication date: March 5, 2020Inventors: Steven Griffiths, Robert L.
