This toothbrush would operate normally only when the user brushes in a correct manner. It has a brush member slidably mounted to a handle. A latching arrangement is provided between the brush and the handle such that when the toothbrush is operated incorrectly in the direction along its longitudinal axis, the toothbrush would either slide freely in and out or completely detach from the handle rendering it inoperable. When brushing with the correct motion in the up and down direction perpendicula...

Training apparatus that includes a base unit and foot plates moveably arranged on the base unit for movement in opposite directions and in an essentially same plane. The foot plates are adapted to accommodate the feet of a user. A support unit, which is adapted to support at least one of upper extremities or a head region of the user, is rotatable around an axis essentially perpendicular to the same plane. A transmission mechanism is coupled to the foot plates and the support unit so that moveme...

The seat (10) of a training device is connected via parallelogram arms (6a, 6b) to a base frame (2) so that it can execute circular-segment movements in reference to the base frame. A training force transmission frame (26) is articulated to a parallelogram arm, and one end is mounted to a crank mechanism (22) that acts on a belt pulley (24) which is connected via a belt (24) to a flywheel (38). A brake (40) (against which the trainee works) acts on the flywheel. A grip holder (30) with handgrips...

The present invention features methods and apparatus for providing tutorial information for a computer program application through a training agent activated by a user of the application. The agent takes control of the application interface and performs actions, such as finding and displaying tutorial information, in response to application user interface commands. The relation between the user interface commands and the actions is stored in a database used by the agent.

An aerodynamic device, such as a projectile includes an elongated forebody, and an aft section secured to the forebody. The aft section acts as a d control device, and includes a connecting member that extends integrally in a conically shaped flared section, for generating a lift force to help stabilize the projectile during forward flight. The aft section further includes a flange that extends from the flared section, and that provides velocity decay and optimal drag, in order to limit the proj...

Training ammunition including a projectile disposed in a cartridge case, the projectile having a rear portion with an axially extending recess and a charge disposed therein, a cover cap extending over the rear of the projectile in a formfitting manner, and at least one obturation member disposed proximate to the cover cap, the cover cap having an outer diameter at least equal to and/or slightly greater than the caliber of the projectile.

An exercise apparatus and method for training athletes or rehabilitating disabled or injured individuals. The device is used to assist users with training muscle fibers that are difficult to train. This device will allow a coach to assist the user with the development of muscles. A user portion (14) of the belt (60) is used to harness a user during an exercise. A controller portion (12) may be connected to the user portion (14) for applying and controlling resistance during the exercise. The tra...

A training apparatus is disclosed. An illustrative embodiment of the training apparatus includes a base frame, a saddle pivotally carried by the base frame and a handle pivotally carried by the base frame and engaging the saddle.

The present invention is a garment that is fastened about the torso of a user such that that rotation of the garment about the user is inhibited. The garment also illustratively includes a handle extending from a back portion of the garment.

On a training device, in particular for developing human muscles, having a torque-generating unit which comprises an electric motor and a reduction gearing, and whose output interacts with at least one training element offered to the exercising person, an electric motor is designed as a three phase AC motor. Associated with the latter is a frequency converter for adjusting the frequency and amperage of the three phase current supplied to the electric motor. A control unit is provided upstream of...
