Abstract: The invention is a fantasy vault system and method for operating a fantasy league, such as a fantasy sports league. The system is independent from the league participants, namely, a fantasy league commissioner and fantasy competitors. Fantasy data providers provides data whereby the performance of the fantasy competitors can be scored and ranked. Different league accounts can be associated with respective distinct data providers. A data provider can be a fantasy host. The system is, therefore, adapted to scoring competitors based on competition data represented in a plurality of formats. The system may accept default and alternate award schemes from commissioners, the particular scheme to be used depending upon the number of competitors paying their entry fee by a deadline. Entry fees from the fantasy competitors are not handled by the league participants, but are deposited into an account in the vault system, from which they may be transferred to a bank account.

Abstract: A game machine is communicatively connected to a game server and display-outputs a game screen showing a content corresponding to the player's operation by exchanging data with the game server. The response time to the operation is stabilized, and consequently the player does not feel stress due to a variation of the response time to the operation. A reference time storage unit (38) stores a reference time from the player's operation to the display-output of the game screen showing contents corresponding to the player's operation. A waiting unit (32) awaits the display-output of the game screen showing a content corresponding to the player's operation according to the stored reference time.

Abstract: A high-precision torque limiting mechanism capable of limiting an output torque to a magnitude of not more than a prescribed value, as well as to reduce a frictional torque produced upon occurrence of a slip. To accomplish this object, a ball ramp section (13) is attached to a slip clutch section (3) for reducing friction between friction plates (31) and (32) forming the slip clutch section (3) and limiting a torque to be transmitted by utilizing an axial thrust produced at the ball ramp section (13) in accordance with the magnitude of an input torque. The precision with which the torque to be transmitted is limited is enhanced by making improvements to the shape of an internal side surface of a recess (G) formed in each of cam elements (131) and (132) of the ball ramp section (13).

Abstract: A pivot joint for a single blade spring tensioner or double blade spring tensioner generates a biased friction loss at a pivot joint. The friction torque generated in one direction of joint rotation is greater than the friction torque generated in the opposite direction of rotation. In one embodiment, the direction of torque bias at the joints is used to make the damping of the blade spring greater in compression than in extension. High damping in compression and low damping in extension is a desirable characteristic for a tensioner in most applications. The device may be designed to act as a one-way clutch or as a two-way clutch. The device may also be designed to apply large friction torques only when the joint undergoes large amplitude motions (loss of control).

Abstract: A tensioner for a power transmission system includes two tensioning arms operatively engaged with a strand of either the chain or the belt of the power transmission system. The upper end of each tensioning arm is connected to a one way rotational clutch which is pivotally mounted between the upper ends of the tensioning arms. The one way clutch rotates in one direction in response to changing chain loads to adjust the tension substantially equally on both strands at the same time. In order to prevent over-tensioning, a damping means is included in the one-way clutch. When a pre-determined overload threshold is reached, the amount of torque required to overcome the coefficient of friction of a spring in the damper allows the one way clutch to slip in the direction opposite from its normal rotational direction, thereby relieving the overload condition on the chain.

Abstract: An exercise ring with properties ideally suited for exercising by a user sitting at a desk or work station is disclosed. The exercise ring is nested within the outer rim of a computer mouse pad such that a user may easily remove the device and use it while seated at a desk or work station and serves the second function as a wrist rest when mounted on the mouse pad.

This combination of exercise ring properties has been found to provide an optimum work out when exercising in a confined space and reduces the chance of the user being impacted by an accidentally released exercise ring.
