An acoustic sensor is configured to provide accurate and robust measurement of bodily sounds under a variety of conditions, such as in noisy environments or in situations in which stress, strain, or movement may be imparted onto a sensor with respect to a patient. Dimensions for a table are identified, and at least one block in the table is associated with a dimension value for each dimension, where each block comprises contiguous storage pages. An alternate embodiment includes a ladder stabilizer for an extension ladder comprising an extending leg and a stabilizer arm with the top of the extending leg attaching to a slide lock that slides along a channel mounted on the side of the ladder.
