A housing (202) for a Time-of-Flight (ToF) range meter (201), comprising a wall structure (203) defining a first optical beam path (222) to an emitter (220) of the ToF range meter, and a second optical beam path (232) to a detector (230) of the ToF range meter; and a transmissive optical diffusor (224, 234) configured to cover the beam path to at least one of said emitter and said detector. The housing may be connected to a ToF range meter into a ToF ranging device (200). Such a ToF ranging device (200) may be incorporated in measurement system for use in an exercise machine, wherein the ToF ranging device is directed to measure a distance to the reflector member to determine a distance which correlates to the weight of the selectively engaged weights.

An apparatus includes an acquisition unit configured to acquire a measurement result of a golf swing motion, and a calculation unit configured to calculate a behavior of a shot by the golf swing motion. The measurement result includes a head speed, an incident angle, and a face angle at the time of striking. The behavior includes an initial speed, a vertical launch angle, and a back spin amount. The calculation unit calculates the behavior by substituting the head speed, the incident angle, and the face angle, all of which have been acquired by the acquisition unit, into a predetermined arithmetic formula having a plurality of variables including at least a head speed, an incident angle, and a face angle at the time of striking of a golf club head.

An apparatus includes a bumper assembly configured to be securely positioned along a length of a perimeter of a miniature golf course having a ball cup configured to receive a golf ball therein. A light-emitting assembly is supported by the bumper assembly. The light-emitting assembly is configured to emit light externally from the bumper assembly. A ball-detection device configured to be positioned proximate to the ball cup of the miniature golf course. The ball-detection device is configured to transmit a detection signal indicating that the golf ball was received by the ball cup of the miniature golf course. A controller assembly is configured to be in electrical communication with the light-emitting assembly. The controller assembly is also configured to be in electrical communication with the ball-detection device.

A golf launch monitor is configured to determine a flight characteristic of a golf ball. The golf launch monitor includes two low-speed cameras, a trigger device, and a processor. The trigger device is configured to detect a golf swing. The processor is configured to instruct, upon the trigger device detecting said golf swing, the first camera to capture the first ball image; instruct the second camera to capture the second ball image after a time interval, wherein the time interval is less than the first frame rate and the second frame rate; and determine, based at least in part on the first ball image and the second ball image, the flight characteristic of the golf ball.

Systems and methods for motion capture and analysis are described. The system may include a motion sensor unit configured to capture data associated with movement of an object. The motion sensor unit is configured to be directly or indirectly coupled to the movement object at a first location. The system also includes a processor to process the captured data to determine one or more values and to translate the data and/or values to correspond to a second location on the movement object located away from the first location. The data and/or values, including translated data and/or values, may be transmitted by wireless transmitter and displayed by a display unit.

Apparatus, systems, and methods are provided for measuring and analyzing movements of a body and for communicating information related to such body movements over a network. In certain embodiments, a system gathers biometric and biomechanical data relating to positions, orientations, and movements of various body parts of a user performed during sports activities, physical rehabilitation, or military or law enforcement activities. The biometric and biomechanical data can be communicated to a local and/or remote interface, which uses digital performance assessment tools to provide a performance evaluation to the user. The performance evaluation may include a graphical representation (e.g., a video), statistical information, and/or a comparison to another user and/or instructor. In some embodiments, the biometric and biomechanical data is communicated wirelessly to one or more devices including a processor, display, and/or data storage medium for further analysis, archiving, and data mining. In some embodiments, the device includes a cellular telephone.

A golf instruction method, apparatus and analytics platform for determining the state of a putted golf ball relative to a target using information about the golf ball and external variables and remotely displaying the same, comprising a base unit, a mobile device or terminal, and an associated computer program including an analytics engine for analyzing a user's performance. The computer program determines whether and how a putted golf ball has missed said target and then stores, aggregates and displays that information for a user. The analytics engine is operable to aggregate data, analyze data and then correlate a user's actual skill proficiency to ball performance.

Disclosed is an augmented learning system for tai-chi chuan, including a head-mounted display put on a head of a learner, and a plurality of action sensors worn on the head or a body of the learner. The action of the learner is sensed by the action sensors, which generate and wireless transfer corresponding sensing signals to the head-mounted display. Based on the sensing signals, the head-mounted display constructs and shows images of the learner as well as a virtual coach demonstrating tai-chi chuan in front of the learner. Also, virtual assistants at different positions demonstrate the same tai-chi chuan such that the learner clearly watches each detailed move of tai-chi chuan at various views. Therefore, the present invention helps the learner effectively self-examining and self-correcting every move by means of video and audio so as to overcome learning obstacles and speed up learning progress for tai-chi chuan.
