Abstract: A system and method are described for presenting on-line survey invitations to users over a network. The system enables selectively presenting survey invitations to users in accordance with a survey recruitment definition associated with a tag embedded within an on-line advertisement downloaded and executed on a user computer. If a determination is made by a survey recruitment server that a requestor is to be a potential control (unexposed) survey participant, then instructions are issued to the requesting user computer to obstruct presentation of the on-line advertisement which caused the issuance of the request for a survey invitation from the user computer.

Abstract: A creeper device is provided in a unibody platform to provide highly maneuverable support for a person in a generally horizontal position with either a rigid one piece platform or alternatively, with a two piece foldable hinged construction for convenient transport and storage. The unibody creeper comprises a bottom side having wheels or casters mounted thereon and a top side which may include a foam pad or cushion to support the user comfortably. The wheels are attached to the underside of the support platform and allow the device to be readily moved and maneuvered by the user. The wheels are affixed and positioned such that the head end of the creeper is cantilever supported beyond the forward most wheels to enable a person to enter the opening of a sink type cabinet door and navigate above the raised toe kickboard and cabinet floor while the creeper wheels remain on the floor outside of the cabinet.
