An exercise machine is disclosed. The exercise machine comprises a pancake motor. The exercise machine comprises a torque controller coupled to the pancake motor. The exercise machine comprises a high resolution encoder coupled to the pancake motor.

An exercise machine allows a user to perform a variety of resistance exercises with adjustable resistance levels. The machine is made up of an arm, a user platform, a horizontal base, an adjustable counterweight arrangement, a pull rod, a drive chain system, sprockets, shafts, adjustable fan, a slip bearing, a recoiler, a plurality of wheels, a drive chain system housing, a user back support, a user cable grip, and a circuit-breaking sensitive rubber mat. When the arm is moved upwards (by a user) the pull rod attached to a drive chain initiates the drive chain system rotation. The drive chain system rotation includes an adjustable weight fan that creates resistance to the arm's upper movement through inertia. The adjustable counterweight arrangement determines the arm drop speed and the arrangement has multiple positions. Other variants include a plurality of electronic encoders.

An apparatus (100) for back improvement and lower-back pain and knees relieving, the apparatus comprising for each foot of a user, including a pedal (40) shiftable along a linear axis, for allowing a foot of the user to exert force on the pedal (40), a sensor (18), for continuously sensing a force exerted on the pedal (40) by the foot, a mechanism for exerting resistance force on the pedal, and a controller (10) for reading a sensing of the sensor, the controller being adapted to instruct the mechanism to exert continuous resistance force on the pedal such that the pedal submits to the foot.

The connected exercise device includes a main body member that receives resistance bands attached thereto where the main body member is flexed during such use. The main body member includes a preferably tubular configuration for slidably receiving a force sensing member that is interconnected to the main body member. At least one strain gauge attached to the force sensing member, which provides a live real time output signal associated with the force sensed by the at least one strain gauge due to the flexing of the main body member. Electronic circuitry is configured and arranged for wirelessly transmitting the output signal to an external computing device for use by the user for enhanced understanding of use of the connected exercise device.

The disclosure herein provides a golf GPS device with a sensor mechanism to automatically switch between video and audio only modes of the device. More particularly, when a player attaches the golf GPS device to a piece of clothing or hat, the device automatically switches to audio-only mode. When the player detaches the golf GPS device, the device automatically switches to video mode, with or without audio. The golf GPS device further includes one or more processors configured to repeatedly determine in which one of the plurality of holes the device is located, to repeatedly compute a distance between the device and a feature of the determined hole, and to cause to display the hole number of the determined hole and the computed distance on the display screen.

Systems and methods for dynamic resistance training are provided that include the use of a dynamic force module. The dynamic force module includes an actuator and controller adapted to control the actuator according to a force profile that specifies the relationship between an operational parameter of the actuator and a measured parameter associated with a user performing an exercise. The dynamic force module is also capable of communicating with a broader network system to facilitate storing and distribution of force profiles and user profile information. The network system further includes features for, among other things, generating and managing force profiles, uploading multimedia content, and tracking user progress.

An exercise machine is disclosed. The exercise machine comprises a pancake motor. The exercise machine comprises a torque controller coupled to the pancake motor. The exercise machine comprises a high resolution encoder coupled to the pancake motor.

An exercise device includes a base defining an inner volume and a top supported by the base, the top defining an aperture. The exercise device further includes a force sensor configured to measure force on the top and a motor disposed within the base and below the top, the motor including a cable extendable through the aperture. The exercise device further includes a controller communicatively coupled to each of the force sensor and the motor. The controller is adapted to actuate the motor in response to forces applied to the top as measured by the force sensor. The controller may also actuate the motor in response to one or more additional parameters related to the speed or force with which the cable is manipulated (e.g., pulled by a user).

An adaptive active training system includes a motion module, a sensing module and a control module. The motion module includes a training unit and a motor connected to the training unit. The motor is configured to bring the training unit to move along a motion trajectory. The sensing module is configured to sense a physiological signal of a user when the user uses the training unit. The control module is connected to the motion module and the sensing module. The control module is configured to calculate a position of the training unit on the motion trajectory, obtain a threshold value corresponding to the position based on a motion model, and determine whether a magnitude of the physiological signal is greater than the threshold value.
