Abstract: A pedal bar system includes a frame, a motor, a pedal shaft, a pedal assembly, and a tensioner. The motor is selectively operable in a forward mode and a reverse mode and is disposed on the frame. The motor shaft is rotatably coupled to the pedal shaft via a drive belt. The pedal assembly is rotatably coupled to the pedal shaft. The tensioner, in communication with the motor shaft and the pedal shaft via the drive belt, has a disengaged position and an engaged position. When the tensioner is in the disengaged position, the drive belt has insufficient tension to rotate the pedal shaft. Conversely, when the tensioner is in the engaged position, the drive belt has sufficient tension to rotate the pedal shaft. Importantly, the pedal shaft is not rotated by the motor in the reverse mode when the tensioner is in the disengaged position.

Abstract: The invention is a pillow that positions the neck enabling the sleeper to keep his airways open and get a good night's rest without snoring. The invention is a rectangular block of foam with a center cavity for an individual's head. The pillow is contoured to allow the lordotic curve of the cervical spine to be maintained and ensures that the upper portion of the thoracic spine is properly supported. Over the neck a foam bridge is formed to hold the jaw firmly in place whether a person lays on his back or sides. The bridge keeps the mandible from opening during sleep prohibiting mouth-breathing and snoring. Both the pillow and the bridge are made of flexible foam that is flexible enough to allow the neck to pass through the opening in the bridge. The bridge is position to keep the mouth closed and the airway open ensuring no snoring.
