A system and method for providing neurological function analysis and treatment to a person using virtual reality systems. The system and methods comprise a data capture system that receives, fuses, and integrates sensor data from various sensors, a virtual reality engine which uses the integrated sensor information to generate an environmental model and a tracking model, and a therapeutic engine which can assess both the cognitive and physical condition the person, determine a training regime based on the assessment, and apply therapies while the person is engaged in a virtual reality environment. The training regimen can comprise brainwave entrainment and/or dual-task stimulation via virtual elements. In some embodiments, a medical professional may engage with the person in the virtual reality environment.

A weight arm assembly for use with a weight lifting rack is provided, the weight arm assembly including a mounting bracket configured to be attached to a vertical surface in a fixed position, an arm mount configured to be coupled to the mounting bracket so as to be pivotable about a first axis, a stop member coupled to the arm mount and configured to move between an engaged position to prevent pivoting of the arm mount through interaction with the mounting bracket, and a disengaged position to allow pivoting of the arm mount, and a weight arm configured to be coupled to the arm mount, proximate a first end of the weight arm, so as to be pivotable about a second axis substantially orthogonal to the first axis.

A bi-directional exercise machine has a work arm, first and second cams coupled to the work arm, a resistance mechanism, and a pulley assembly that couples the resistance mechanism to the work arm via the first and second cams so that movement of the work arm is resisted by the resistance mechanism according to first and second resistance profiles provided by the first and second cams, respectfully. A primary pulley cable has a first end coupled to the first cam and a second end coupled to the second cam. When the work arm is in a rest position, the ends of the primary pulley cable extend from cable tracks of the cams, respectively, at a tangent so that the resistance mechanism applies a resistance force on the work arm via the pulley assembly immediately upon movement of the work arm out of the rest position.

A weight lifting device including a housing having first frame having first vertical channel for accommodating first weight holding means, and second frame having second vertical channel for accommodating second weight holding means, wherein first vertical channel and second vertical channel are dimensioned so that first weight holding means and second weight holding means can move up and down, when in use, in first vertical channel and second vertical channel, respectively. The weight lifting device also includes a handle bar pivotably connectable to first weight holding means and to second weight holding means from first end of handle bar and second end of handle bar, respectively. The weight lifting device further includes at least one of: first holding bar, second holding bar, first pivotable arm, and second pivotable arm, arranged between pivotably connectable handle bar and first weight holding means and second weight holding means.

An integrated fitness system including a slidable unit that is slidably attached to a column vertical to the ground and that has exercise units mounted thereon. The exercise units are disposable in any of a plurality of configurations and have arms that are rotatable in any of a plurality of planes. The exercise units can be positioned along the column at any of a plurality of heights by sliding the slidable unit along the column to allow a user to use the exercise units for both arm and leg exercises.

An exercise apparatus comprising: a frame; first and second vertical guides coupled to the frame; first and second carriages carried on the respective first and second vertical guides, each of the first and second carriages having an upper carriage portion, a lower carriage portion and a carriage locking mechanism operable to lock and release the lower carriage portion to a selected vertical position along the first and second vertical guides; and an exercise bar coupled to the upper carriage portion of the first and second carriages, the exercise bar operable to translate or rotate to actuate the carriage locking mechanism.

An exercise machine comprises an arm support, including: a carriage configured to slide within a track attached to the exercise machine; and a support assembly that floats the carriage relative to the track, wherein the support assembly is disengaged by the application of force via the arm. An exercise machine comprises a rotatable column, wherein the column supports an arm, and a gear detent mechanism to support a discrete number of positions for the rotatable column. An exercise machine comprises a tiltable arm, and a mechanism to support a discrete number of positions for the tiltable arm.

A door mount system for securing exercise devices to a door for use by a user. The door mount system includes a support member, a securing member, an attachment member, and an adjustment member. The adjustment member is adapted to move the securing member. A securing member is adapted to press on the door to removably connect the support member to the door. The attachment member is adapted to connect to an exercise device. The door mount system may further include guide members and slots. The guide members slidably move in the slots to prevent rotation of the securing member. The attachment member may include one or more eyelets adapted to connect to the exercise device.

The present invention provides a competitive weightlifting system capable of interacting with and comparing weightlifting performances of multiple users, and creating competition between such users by displaying a ranked list of performances by those users. The system may include a frame for supporting and guiding a lift bar, sensors mounted to the frame for measuring and refereeing the performance of a user, a controller housed in the frame for tracking and ranking user performances with an interface for creating and logging into user profiles, and a communication device for sharing user performance data with other remote competitive weightlifting systems (e.g., competitive weightlifting systems in other gyms or homes) in order to create a wide-ranging competition between, and ranked leaderboard of, the many users.

The present invention discloses a power adjustment device. The power adjustment device includes a steel cylinder and a piston arranged inside the steel cylinder in a sliding mode, wherein the piston is fixedly provided with a guide rod, the guide rod being connected to a dustproof cover in a sliding mode, and a steel cable being fixed to an upper end of the guide rod; the piston is provided with a one-way air guide structure, the one-way air guide structure including an air guiding channel, the air guiding channel including a circular upper channel and a circular lower channel, and an adjustment ball being arranged inside the upper channel; and purposes of eliminating vibration, lowering noise, eliminating potential safety hazards, being more convenient in assembly and lowering cost are achieved.
