Abstract: A method of managing a digital certificate by a computer system can include the steps of receiving, the at the computer system, a business request for a digital certificate from a requester and transmitting, by the computer system, the request to a first approver. The method can further include, upon approval by the first approver, transmitting, by the computer system, the request to a second approver, upon approval by the second approver, transmitting, by the computer system, the request to a certificate manager, transmitting, by the computer system, the request to an implementer and receiving, by the computer system, from the implementer, technical information related to the request and transmitting, by the computer system, a certificate to a certificate supplier.

Abstract: An exercise apparatus comprises at least one upright joined to a cross bar provided with a limb support means. The limb support comprises an upright connecting cross bar of such a length that the cross bar is spaced from the floor sufficiently such that, in use, the legs of the user can rest on the cross bar when the user is positioned beneath the cross bar. The cross bar also being sufficiently spaced from the floor such that, in use, the limb support comprises a handgrip to enable a user to push down on the exercise apparatus so that the exercise apparatus supports at least some of the user's weight. The limb support comprises two outer concave regions that are relatively spaced along the longitudinal axis of the cross bar. The cross bar is provided with a third inner concave region in between the two outer concave regions.
