Abstract: The present invention discloses a child seat comprised of a seat structure and a child restraint system that allows a restraint to be easily removed from the seat structure and cleaned separately and away from the child seat. The restraint system includes a restraint and a restraint release mechanism. The restraint release mechanism is disposed on the outer side of the seat. The restraint is comprised of at least two child restraint straps. On at least one end of each child restraint straps is a restraint release fastener and on the other end of each strap is a child release fastener. The child restraint fasteners can be releasably connected together on the child receiving side of the seat to secure or release a child from the restraint. Each strap passes through a passage in the seat structure so that the restraint release fastener ends of the child restraint straps extend from the child receiving side of the seat to the outer side opposite the child receiving side. The restraint release fasteners are then releasably secured by the restraint release mechanism such that a single actuation of the restraint release mechanism frees all of the restraint release fasteners. The straps can then be pulled through the passages in the seat and the restraints can be taken to a convenient location for cleaning.

Abstract: Systems and methods are defined for facilitating the audit process involving a business client, an auditor, and a third-party providing confirmations for the client upon the auditor's request. More specifically, an auditor receives an audit number from the audited client as evidence of authorization for requesting confirmation from a third-party, such as a bank or related business entity. The confirmation request submitted by the auditor will be stored in a network-based computer system and transmitted to the relevant third-party. The third-party then provides necessary confirmation data in response to the request and has the confirmation data transferred to the auditor through the computer system over the Internet. The involved third-party can be a bank or financial institution, another entity in business relationship with the client, or any other entity that has access to the requested data associated with the client.
