More particularly, methods, systems and devices are provided that provide and project a user self-image from a first camera onto an image captured by a second camera having a different orientation from the first camera, thereby creating a selfie via image overlay and enhancing the safety of the user.

Abstract: In general and for simplicity of description, the present invention provides realtime feedback to a user of exercise equipment, showing the user the relative input force the user applies between left and right contact points with exercise equipment that has a singular resistance mechanism. By receiving this feedback, a user can balance or adjust to their desired ratio physical effort between the user's left and right engagement points and/or muscle groups with the exercise equipment, thereby achieving desired workouts.

Abstract: A back support for preventing injury to the spinal column that allows a user a limited amount of freedom of rotary motion. The apparatus includes an upper support, which in use extends from a top end approximately at the neck of a user to a bottom end at the thoracic lumbar transition region. At this point, the bottom end of the upper support is connected by way of a limited motion rotary flex joint to a top end of a lower support, which in use extends from the thoracic lumbar transition region to the tail bone or sacrum region. Both the upper and lower supports are contoured to conform with the shape of the spine and surrounding bodily structure to distribute any impact forces, and except for the length and contour, the upper and lower supports are of similar construction. A preferred embodiment of the supports includes a rigid core member extending the length of each support.
