Abstract: In a data storage device, information regarding the operation of the device is gathered by a plurality of information providers or sources, such as counters, each configured to indicate a data point and/or count the occurrence of events with respect to the data storage device. A device control is configured to present an external prestructured arrangement of potential monitoring of the information providers, for external selective monitoring of a portion of the information providers in accordance with the prestructured arrangement. In one example, the prestructured arrangement is an ordered sequence of the information providers, for selective monitoring of a selected number of the information providers taken from the ordered sequence, such as the first “n” of the sequence.

Abstract: A portable tent-like shelter comprises an open frame made of tubular elements which slip fit together to form a roof portion. The frame has four elongated legs extending downwardly from the corners to cause the frame to be free-standing. A fabric cover is placed over the roof portion of the frame and the cover has boxed ends and sides which extend downwardly from the roof portion of the open frame. Elongated, narrow, fabric leg panels are attached to the fabric cover at each of its corners and extend downwardly along the legs of the frame. The leg panels are releasably attached to the legs at the lower ends to place tension through the leg panels to the cover to hold it in place on the frame.
