A method and system are described for examining the interior material of an object from a surface of an object using ultrasound having a frequency of at least 100 kHz. The volume may be bounded, at least in part, by an outer structure and by an object at least partially contained within the outer structure. The server system detects that a customized announcement is to be delivered and the messaging system delivers the announcement to the caller. The compliant equipment 31 registers its own configuration file received from the management server 2 into itself, and then configures the configuration file of the noncompliant equipment 32 into the noncompliant equipment by executing the received configuration script. The ends of at least some of the beams extend beyond the polygon, and are configured for engagement with the attachment elements thereby carrying the frame by the ends. An actuator assembly, including a motor driven actuator operatively coupled by snap-fit connectors to the frame, inclines at least one of the deck boards.
