The disclosed physical exercise apparatus (2) comprises a frame (2′) equipped with a crankset and a saddle (26), the saddle itself comprising a chassis (262) fastened to the frame, two saddle parts (266) and articulation members (267, 268) for articulating each saddle part relative to the frame around a pitch axis (A26), about a roll axis (B26) and about a yaw axis (L26). This apparatus (2) also comprises sensors (30, 50) for detecting a pitch movement (T), a roll movement (R), and a yaw movement (L) of each saddle part respectively about the pitch, roll, and yaw axes, these movements resulting from pedaling made by a user. At least one calculation unit (40) is configured to determine, from output signals (S.sub.30, S.sub.50) of the sensors, angular amplitudes (α, β, γ) of the pitch (T), roll (R), and yaw (L) movements. At least one screen (29) is provided in order to display, depending on the angular amplitudes determined by the calculation unit (40), the position on each saddle part of a bearing point (P.sub.G, P.sub.D) of an ischium of a user in the process of pedaling.

A golf club fitting apparatus and a method for fitting using the apparatus are provided. The golf club fitting apparatus may be attached to a golf club and provide fitting information including effective lie angle and effective loft angle. The golf club fitting apparatus includes a lower surface that contacts a butt end of a grip, an upper surface opposite the lower surface, and a side surface connecting the upper and lower surfaces. An angle indicator is disposed at a predetermined angle relative to a shaft axis of the golf club so as to rest in a neutral position when the golf club is in a normal address position.

A system for transmitting power and data between two circuit boards may include a fixed circuit board having a primary coil and a rotatable circuit board having a secondary coil. The system may further include a sensor in communication with the secondary coil of the rotatable circuit board. The fixed circuit board's primary coil may be inductively coupled to the secondary coil and may provide power and receive data from the sensor when inductively coupled to the secondary coil.

An electromechanical manipulandum device, comprising: a drive system comprising a plurality of electrical motors; an arm driveable by the drive system and having three degrees-of-freedom of motion; a capstan transmission for transmitting actuating force from the drive system to the arm; an end-effector coupled to the arm, the end-effector configured to engage a user and having at least three degrees-of-freedom of rotational motion; and a control system for controlling the drive system such as to provide a force to the end-effector in a selected direction.

Among other things, a rowing technology includes a first rowing machine having an electromagnetic brake providing a resistance to a rower of the machine in each rowing stroke of a series of rowing strokes of the rower An electronic controller causes the resistance of the electromagnetic brake to vary over each rowing stroke in a profile that emulates resistance to which another rower in a shell on water or on a second rowing machine is subjected in each rowing stroke of a corresponding series of rowing strokes.

A method includes receiving a set of treatment plans. Each treatment plan comprising the set of treatment plans may be associated with a user capable of using a treatment device to perform the associated treatment plan. The method also includes receiving healthcare professional profile information. The method also includes identifying treatment device information for each treatment device capable of being used by a cohort of users associated with respective treatment plans. The method also includes using an artificial intelligence engine, wherein the artificial intelligence engine uses at least one machine learning model configured to generate resource deployment predictions, to generate at least one resource deployment prediction. The at least one machine learning model may generate the at least one resource deployment prediction based on at least some treatment plans comprising the set of treatment plans, at least some of the healthcare professional profile information, and at least some of the treatment device information.

A laser mandrel system that self-centers within a hosel bore of a golf club head to allow for precision adjustment of lie and loft is disclosed herein. The mandrel includes a one-piece housing with upper and lower portions, a laser centered within the upper portion of the housing, and a plurality of o-rings extending around an exterior or interior surface of a lower portion of the housing.

An apparatus for natural torso and limbs tracking and feedback for electronic interaction with fall safety support. The apparatus comprises a body harness worn on the body of a user, a support structure designed to bear the weight of the user in the event of a stumble, trip, or fall, and a plurality of tethers attached at one end to the harness and at the other end to the support structure. One or more sensors are integrated into the system to measure aspects of the user's movement and used as input to control a computer system. In the event of stumble, trip, or fall, all of, or a portion of, the user's body weight is borne by the tethers as a safety mechanism to prevent injury. The system is designed to be used with virtual reality systems wherein the user's vision is blocked or obscured by a virtual reality visor.
