Publication number: 20230258427Abstract: The present disclosure explains a system and method for determining a spatial orientation of a weapon in an augmented reality training environment. Fiducial markers are mounted on the weapon and two cameras are mounted on a user's head to capture spatial coordinates of the plurality of fiducial markers. The spatial coordinates of fiducial markers are processed to determine the spatial orientation of the weapon and a simulated discharging of the weapon. Augmented reality imagery is generated based on the spatial orientation and the detected movement. The augmented reality imagery corresponding to the spatial orientation and discharging of the weapon is rendered for the user with the head-mounted display.Type: ApplicationFiled: November 3, 2022Publication date: August 17, 2023Applicant: Cubic CorporationInventors: Keith William Doolittle, Lifan Hua, David Robert Simmons, Adam Robb Syme, Robyn Ann Yost, Peter Jonathan Martin, Carson Alan Brown, Michele Fleming, Vern Edgar Campbell

Patent number: 11272657Abstract: A strand trimmer and method of use thereof. The strand trimmer includes a pair of pivotable arms each having a motor, a follower wheel, and a cutter-spindle assembly disposed thereon. The arms are biased toward one another and are guided by the follower wheels to pivot around obstacles passing between the arms. The motor rotates the cutter-spindle assembly to move cutting strands extending therefrom through a cutting path with sufficient rotational velocity to cut vegetation. The cutter-spindle assembly includes a reloadable spool and a strand-feed mechanism. The strand-feed mechanism includes a solenoid actuated plunger within a shaft of the cutter-spindle assembly which operates to non-contactingly actuate the plunger to feed out a length of strand. The solenoid is non-rotatably carried on the trimmer arm while the shaft of the cutter-spindle assembly is encircled by and rotated within the solenoid.Type: GrantFiled: February 25, 2019Date of Patent: March 15, 2022Assignee: Trimverse LLCInventors: Robert Simmons, Mark T.
