A vibrator apparatus includes a moving coil, which is rigidly attached to a member, e.g. a frame or beam, of a vibration device. The moving coil is for an elected vibration mode of the apparatus configured to receiving electric signals, e.g. pulsating and/or sinusoidal electric signals, from a signal unit. The moving coil co-operates with a permanent magnet, which is suspended by springs attached to the member, and the coil and the magnet are mutually linearly and coaxially movable upon application of electric signals to the moving coil. An actual distance of movement being part of a distance between extreme positions and being less than the axial length of the moving coil. The springs are located at a distance from a respective axial end portion of the permanent magnet.

A gyroscopic exercise apparatus, comprising: at least one control-moment gyroscope; at least one motion sensor for sensing movement of the apparatus; at least one spindle motor for providing rotation to a rotor of the gyroscope; and, at least one reversible motor for providing rotation to at least one gimbal of the gyroscope.

An apparatus and method for automating neuromuscular training. The apparatus may be used in conjunction with a human trainer or by a person training alone. The apparatus and method may be applied to various forms of neuromuscular training, The apparatus may be employed by a person desiring training in an environment with a human trainer as well as, or alternatively, in a home environment for personal training.

Embodiments enable training of relative motions between body parts such as the head, neck, shoulders, upper torso, lower torso. These relative motions may be linear and/or angular. Pressure/sensor assemblies facilitate both the suggestion of desired motions as well as sensing of the person's neuromuscular response to these suggestions.

Methods for instructing a user to perform head and neck exercises with head and neck apparatuses are disclosed. The apparatus may include a member operatively arranged with a valve mechanism with a threshold pressure. The apparatus may further include an acoustic apparatus, membrane, chromogenic material, or moveable element that may be configured to respond when the pressure within the member is greater in magnitude than the threshold pressure. The head and neck exercise apparatus may also include a member operatively arranged with an acoustic apparatus, membrane, chromogenic material, or moveable element that may be configured, without a valve mechanism, to respond when the absolute pressure within the member is greater in magnitude than a threshold absolute pressure.

Training neck muscles in such a way as to improve responsiveness to head acceleration forces, and to help prevent concussion and/or screening subjects who are at high risk of concussion, especially from contact sports or military activities, may be accomplished by a device and/or method of training that incorporates an adjustable centripetal force about a fixed axis on the head. The centripetal force may be adjusted through varying the weight and/or length of a force arm, and neck muscle performance may be measured by a number of revolutions of the force arm completed over a set time period or a time required to complete a pre-determined number of revolutions of the force arm.

The neck and shoulder exercise device is a harness worn on the head of a person. The neck and shoulder exercise device attaches to a commercially available weight machine commonly used for strength. By attaching the weights associated with the weight machine to the neck and shoulder exercise device the person can use the weight machine to train the muscles supporting the head of the person. The neck and shoulder exercise device comprises a plurality of straps, a plurality of seams, a plurality of hooks, and a fastener. The plurality of seams: 1) interconnects the plurality of straps to each other; and, 2) attaches the plurality of hooks to the plurality of straps. The fastener secures the neck and shoulder exercise device to the head of the person. The plurality of hooks are used to attach the neck and shoulder exercise device to the weight machine.
