Abstract: A system and methods for the treatment of amblyopia are described. The system includes a display system capable of delivering a second image to a second eye of a patient and a first image to a first eye of a patient. The system also includes a controller capable of delaying the delivery of the second image to the second eye of the patent. The controller is configured to receive the second image and the first image. The controller is also configured to identify a delay factor associated with the second image. The controller is also configured to provide the first image to the display system for viewing by the first eye of the patient. The controller is also configured such that after a delay determined by the delay factor, the controller provides the second image to the display system for viewing by the second eye of the patient.

Abstract: A welding system can manage wire feeders such that unused wire feeders are conveniently stowed. The welding system include two or more wire feeders individually attachable to a welding torch. The welding system includes one or more mount points to secure unused wire feeders and enable convenient swapping of an active wire feeder.

Abstract: Methods and systems for maintaining user attention during a treatment are disclosed. The method comprises measuring at least one user parameter when presenting treatment content to the user via at least one display screen, determining whether the user is engaged with the presented treatment content based on the at least one measured user parameter, presenting an attention booster to the user upon determining the user is not engaged with the treatment content. The system comprises at least one display apparatus configured to present treatment content to the user and a processor configured to execute instructions stored on a memory to measure at least one user parameter when the treatment content is presented to the user, determine whether the user is engaged with the presented treatment content based on the at least one measured user parameter, and output to the display apparatus an attention booster to the user upon determining the user is not engaged with the presented treatment content.

Abstract: In various embodiments, a head-mounted apparatus having first and second display screens for, respectively, displaying visual content dichoptically to left and right eyes of a user is utilized to treat, improve, or prevent degradation of the user's vision.

Abstract: In various embodiments, methods of treating, improving, or preventing degradation of a user's vision incorporate the display of visual content dichoptically to the left and right eye of the user while the accommodative demand placed on the left eye and/or the right eye is altered.

Abstract: The invention described herein generally pertains to systems and methods related to repeatable and accurate setting of welding torch lead and lag positions, particularly with orbital welding systems. Specifically, a torch is coupled with a lead-lag coupler having a stop lug. A stop set with a stop pin is rotated to a desired position of lead or lag and secured. The lead-lag coupler, and torch which rotates therewith, are then unsecured and rotated until the stop lug contacts the stop pin. In this position, the torch is maintained at the desired angle. The stop pin remains in place throughout operation(s) to permit quick, accurate return to the desired angle if the torch is temporarily moved out of position.

Abstract: The invention described herein generally pertains to locking mechanisms for levers operable to mount a tractor unit to a guide track and to engage a drive gear of the tractor unit to a track gear of the guide track. The levers for mounting the tractor unit and/or to engage the drive gear are lockable in a closed position. The closed position relates to a state of the levers when the tractor unit is mounted on the guide track or when the drive gear is engaged with the track gear. The levers can be easily operable to mount/dismount or engage/disengage, respectively.

Abstract: The claimed subject matter provides an anti-backlash nut for use with a leadscrew. The nut can include two or more threaded sections and at least one semi-flexible section. The anti-backlash nut can be of one-piece construction and utilize the one or more flexible or biasing sections to apply one or more forces or offsets to the threaded sections to mitigate backlash.

Abstract: An ergonomic shower chair with built in bidet, comprising an ergonomic seat portion, an ergonomic back portion with lumbar support, and a bidet portion. Water enters the bidet portion by holding a hand-held showerhead against the main opening of the bidet portion, and is sprayed towards the user's perineal area through bidet nozzles positioned within holes along a longitudinal groove in the seat portion. Because these holes have inner diameters that are wider than the outer diameters of the bidet nozzles, water is drained away through the interstices between the hole walls and the bidet nozzles. The seat portion includes additional drainage holes for fast drainage.

Abstract: A rotary drag-type drill bit, for drilling holes in subsurface formations, comprises a bit body having a leading face and a gauge region, a number of blades formed on the leading face of the bit and extending outwardly away from the axis of the bit so as to define between the blades fluid channels leading towards junk slots in the gauge region. Cutting elements are mounted along each blade, and nozzles in the bit body supply drilling fluid to the leading face of the bit for cleaning and cooling the cutting elements. At least some of said blades each have a leading edge which is non-linear, or convexly or concavely curved, as viewed axially of the bit, as it extends outwardly away from the axis of the bit. Blades of different shapes may be located alternately around the axis of the bit. The junk slots at the gauge region, and the kickers between which they are formed, may vary in width around the periphery of the bit, and may be inclined to the axis of the bit.
