Abstract: A direct shift continuously variable transmission for a vehicle engine includes a variator having a toroidal cavity; a plurality of traction roller rotatably and radially located within the toroidal cavity; an input shaft rotatably disposed within the variator, the input shaft being adapted to receive a torque from the vehicle engine; an input disk coaxially connected to the input shaft and frictionally contacting the traction roller to provide a rotational force to the traction roller; an output disk opposed to the input disk and frictionally contacting the traction roller, the output disk being annularly rotatable by receiving the rotational force from the traction roller; and an output shaft coaxially connected to the output disk and receiving the rotational force from the output disk.

Abstract: An electronic learning aid device which includes a removable module including display and input controls, capable of operating, independent the electronic learning aid towards extending the functionality of the device and encourging it's continued use. Enhanced entertainment activities are presented to the child when the child reaches a certain proficiency in executing educational activities presented when the removable unit and the base unit operate together.
