Abstract: There is disclosed a system for engaging in exercise. The system includes a communications interface for receiving instructions from control software controlling operation of the exercise device, a resistance device for generating resistance to the exercise and applied to the exercise device, the resistance device for increasing or decreasing resistance for the exercise under control of the control software, and the control software operating to generate a simulated haptic movement, using the resistance device, by temporarily altering the resistance applied to the exercise device by the resistance device.

Abstract: A single-sprocket system for integration into a bicycle trainer, the system including a sprocket having teeth about a perimeter of the sprocket, a first planar side, and a second planar side, wherein the teeth of the sprocket are configured to engage a chain of a bicycle mounted to the bicycle trainer. The system further includes a first chain guide adjacent the first planar side of the sprocket, wherein the first chain guide is configured to re-engage the teeth of the sprocket with the chain when the chain has become disengaged from the teeth of the sprocket towards the first planar side, and a second chain guide adjacent the second planar side of the sprocket, wherein the second chain guide is configured to re-engage the teeth of the sprocket with the chain when the chain has become disengaged from the teeth of the sprocket towards the second planar side.

Abstract: Images are overlaid using a personal viewing device, such as a head mounted display. The personal viewing device includes a mount, an electronic display, a lens, and an electronic circuit. The electronic display, lens, and electronic circuit are physically attached to the mount. The electronic display and lens are positioned by the mount so that an eye views the electronic display through the lens. The electronic circuit overlays a first image with a second image to produce an overlaid image. The electronic circuit then displays the overlaid image on the electronic display. The electronic circuit can include an image generating device. The image generating device can generate the first image and/or the second image. The image generating device can be a video player or a processor. The personal viewing device can further include a wireless transceiver attached to the mount.

Abstract: An illumination assembly includes a light source, which is configured to emit optical radiation. A transparency containing a plurality of micro-lenses, which are arranged in a non-uniform pattern and are configured to focus the optical radiation to form, at a focal plane, respective focal spots in the non-uniform pattern. Optics are configured to project the non-uniform pattern of the focal spots from the focal plane onto an object.

Abstract: An apparatus, methods and systems to provide a personal viewing device configured to display an image. The personal viewing device configured to be worn by a user. At least one sensor coupled to the personal viewing device. At least one camera coupled to the personal viewing device and facing outwardly with respect to the personal viewing device. A processor configured for interaction analysis. The processor in communication with the personal viewing device, the at least one sensor and the at least one camera.

Abstract: Devices and methods for determining various occurrences and anomalies within a step are provided. A device to determine characteristics of a step includes at least one sensor to measure acceleration of a foot in at least two directions, at least one processor to execute instructions stored in a memory and to determine accelerations in first and/or second directions meet criteria to determine a footstrike and a push off of a foot from a surface. Slipping of feet while walking and running, clipping of feet while walking and running, and tripping and falling while walking and running may be indicators of overall health and fitness, particularly in older individuals.
