A vehicular power generation system includes a power generating device disposed at a vehicle. The power generating device generates electricity responsive to manual operation of an input component of the power generating device by an occupant within an interior cabin of the vehicle. Responsive to the occupant manually operating the input component of the power generating device, the vehicular power generation system outputs electricity generated by the power generating device to electrically charge a battery of the vehicle or electrically power an electrical device within the vehicle.

In one embodiment, a computer-implemented system includes a treatment apparatus configured to be manipulated by a user while performing an exercise session, patient interfaces associated with users, and a server computing device configured to receive treatment data pertaining to the user, determine whether at least one characteristic of the user matches at least one second characteristic of a second user, where the second user belonging to a cohort. Responsive to determining the at least one characteristic of the user matches the at least one second characteristic of the second user, the server computing device is configured to assign the user to the cohort and select, via a trained machine learning model, a treatment plan for the user. Responsive to transmitting a signal to the patient interfaces of users in the cohort, the server computing device enables the patient interfaces to establish the virtual shared session between the patient interfaces.

In one embodiment, an exercise cycle includes a crankshaft, cranks mounted to the crankshaft, a drive mechanism including a ferromagnetic flywheel that rotates in response to rotation of the crankshaft, and a non-contact force adjustment mechanism with which a force required to rotate the flywheel can be adjusted, the force adjustment mechanism including a pivotable member to which magnets are mounted, wherein the magnets can be moved closer to the flywheel when the pivotable member is pivoted toward the flywheel to increase the force required to rotate the flywheel and can be moved farther away from the flywheel when the pivotable member is pivoted away from the flywheel to decrease the force required to rotate the flywheel.

An exercise system includes a rowing exercise device and a chair. The rowing exercise device achieves a lower limb exercise which includes repetitive extension and flexion of at least a knee joint and a hip joint. The chair is the one on which a user who performs the lower limb exercise using the lower limb exercise device sits. The chair includes a seat on which the user sits and a support mechanism capable of supporting the seat in such a manner that the seat can carry out a roll oscillation. The seat carries out a roll oscillation during the lower limb exercise, which causes a motion linkage between a lower limb and a trunk.

A lower limb exercise device that enables a user to perform a lower limb exercise effectively is achieved. A lower limb exercise device according to one embodiment of the present disclosure enables a user to perform a lower limb exercise while the user is seated on a chair. The lower limb exercise device includes exercise equipment for the user to perform the lower limb exercise, and a restriction mechanism configured to restrict movement of at least one caster of the chair from a reference arrangement range of the caster during the lower limb exercise.

A power operated exercise apparatus includes two drive mechanisms configured to drive a left pedal and a right pedal, and a position measuring device, force measuring devices for measuring positions and force conditions of the pedals. A control unit is configured to control the drive mechanism and receive measurement content of the measuring devices, and storing a plurality of exercise programs for being selected by the user. During at least one specific operation period, the control unit repeatedly determines in which directions the left pedal and the right pedal should be moved according to information of positions and force conditions of the pedals so as to meet the displacement path and the correlation of a selected one of the exercise programs and to immediately control the left drive mechanism and the right drive mechanism to respectively drive the left pedal and the right pedal to move in a determined direction.

A rowing exercise device includes: a pair of pedals; and a device body that guides the pair of pedals in such a way that the pair of pedals repeatedly move along a predetermined trajectory. A user performs a lower limb exercise by putting his/her feet on the pair of respective pedals. Each pedal is configured in such a way that a relative roll turn of a forefoot part relative to the device body is prevented while a relative roll turn of a rearfoot part relative to the forefoot part is allowed, whereby a relative roll turn of the forefoot part relative to the rearfoot part occurs during the lower limb exercise.

Systems and methods for identifying a condition of a user. A treatment apparatus is configured to be manipulated by the user for performing an exercise, and an interface is communicably coupled to the treatment apparatus. One or more sensors are configured to sense one or more characteristics of an anatomical structure of the user. A processing device and a memory is communicatively coupled to the processing device. The memory includes computer readable instructions, that when executed by the processing device, cause the processing device to: receive, from the sensors, one or more sensor inputs representative of the one or more of characteristics of the anatomical structures; calculate an infection probability of a disease based on the one or more characteristics of the anatomical structures; and output, to the interface, a representation of the infection probability.

An exercise apparatus having a pulley, a pair of stabilizing assemblies each configured to couple a front portion of a respective pedal element to each side of the pulley, a looped belt configured to couple the pulley to a resistance assembly, a tension stabilizer configured to maintain a tension of the looped belt on the pulley, and the resistance assembly configured to assert an adjustable resistance to the pedal elements through the looped belt. The exercise apparatus also comprises a resistance band extension for performing additional exercise using resistance bands and a transport mechanism for transporting the exercise apparatus and securing the exercise apparatus to a chair wheel or other structure during exercise.
