A system that measures a swing of equipment (such as a bat or golf club) with inertial sensors, and analyzes sensor data to create a rotational profile. Swing analysis may use a two-lever model, with a body lever from the center of rotation to the hands, and an equipment lever from the hands to the sweet spot of the equipment. The rotational profile may include graphs of rates of change of the angle of the body lever and of the relative angle between the body lever and the equipment lever, and a graph of the centripetal acceleration of the equipment. These three graphs may provide insight into players' relative performance. The timing and sequencing of swing stages may be analyzed by partitioning the swing into four phases: load, accelerate, peak, and transfer. Swing metrics may be calculated from the centripetal acceleration curve and the equipment/body rotation rate curves.

Athletic performance monitoring systems and methods, many of which utilize, in some manner, global positioning satellite (“GPS”) data, provide data and information to athletes and/or to equipment used by athletes during an athletic event. Such systems and methods may provide route information to athletes and/or their trainers, e.g., for pre-event planning, goal setting, and calibration purposes. Such systems and methods optionally may provide real time information to the athlete while the event takes place, e.g., to assist in reaching the pre-set goals. Additionally, data and information collected by such systems and methods may assist in post-event analysis for athletes and their trainers, e.g., to evaluate past performances and to assist in improving future performances.

An intelligent interactive real road simulation training device that simulates the real road grade and slope change while playing video based on the geographic location of the road from the pre-processed video and the speed of the user. With the video playing, the user sees the road moving as the user moves, and the speed of the road moving by is based upon the user's speed on the exercise training equipment. The user also feels the grade and slope change as the road grade and slope changes on the video. The invention can be integrated into any exercise training equipment such as a bicycle trainer or treadmill.

A device includes a signaling means and a motion sensor, and logic for activating or controlling the signaling means in response to a sensed motion according to an embedded logic. The device may be used as a toy, and may be shaped like a play ball or as a handheld unit. It may be powered from a battery, either chargeable from an AC power source directly or contactless by using induction or by converting electrical energy from harvested kinetic energy. The embedded logic may activate or control the signaling means, predictably or randomly, in response to sensed acceleration magnitude or direction, such as sensing the crossing of a preset threshold or sensing the peak value. The visual means may be a numeric display for displaying a value associated with the count of the number of times the threshold has been exceeded or the peak magnitude of the acceleration sensed.

A multifunctional ranging telescope includes a main body, a wind direction and wind speed sensing device, a display device and a power source. The wind direction and wind speed sensing device is movably connected to the main body and includes a sensing element. When the wind direction and wind speed sensing device moves to a sensing position, the sensing element is located outside the main body. The display device is located on a surface of the main body and electrically connected to the wind direction and wind speed sensing device to display a wind direction and wind speed information. The power source is configured to supply power to the wind direction and wind speed sensing device and the display device.

A stationary indoor “smart” training bicycle includes a unique combination of adjustable components to provide configurable dimensions to adjust the frame size of the indoor bicycle to properly fit a rider. A system is also provided to process a digital image of an outdoor bicycle and determine and translate dimensions and adjustments to the indoor bicycle to match one or more dimensions (lengths, angles, separations, etc.) of the outdoor bicycle.

A direct-drive bicycle training system and methods of using the same are provided. The system includes a bicycle trainer that rests on a support surface and supports a bicycle frame in an upright manner with respect to the support surface. The bicycle trainer includes a stator, a rotor that rotates with respect to the stator, a cassette affixed to the rotor, a support frame supporting the stator, rotor, and cassette, and a resistance applying mechanism that operatively couples to a portion of a drivetrain of the bicycle frame and applies varying levels of resistance to the portion of the drivetrain. The support frame moves with respect to the support surface in response to a force applied to the drivetrain of the bicycle frame during use of the bicycle training system, generating a more natural movement of the bicycle and simulating on-road use.

A treadmill includes a frame. A running belt is coupled to the frame so that the running belt is adapted for rotation relative to the frame. At least one sensor is adapted for collecting parameter information regarding the experience of a user of the treadmill. The parameter information is selected from the group consisting of the user's heart rate, total expended calories, stride length, stride force, cadence, pace, distance, resistance level, incline level, carver count, carver cadence, step count, ground contact time, relative position within a race, and relative position on the treadmill. The treadmill also includes at least one light source that is adapted to selectively communicate information to an instructor relating to the parameter.
