Abstract: An apparatus for monitoring the movement of a foundation may include an elevation sensor to detect changes in elevation of the foundation and positioned on the foundation to broadcast a signal responsive to the movement of the foundation; and a receiver to receive the signal responsive to the movement of the foundation and positioned off the foundation to provide a absolute measurement of the movement of the foundation.

Abstract: A pest/debris infiltration prevention device in the form of a netting barrier that spans a passageway at the floor level. The netting barrier assembly is mounted to the supportive framing of the passageway by opposing tensioning mechanisms that provide tension along the netting barrier. The different engagements of the upper and lower portions of the netting barrier to the tension mechanisms enables the netting barrier to be biased in an upright position and pivot about the floor level to a prone position when stepped on, run over by a wheel or otherwise top loaded, and spring back upright when unloaded. The present invention permits vehicles or other objects to pass in and out of the passageway whilst still performing its core function of preventing ingress of unwanted elements.

Abstract: A method of monitoring a foundation of a building. The method includes placing altimeters at corresponding locations in the building. The method also includes measuring, using the altimeters, corresponding measurements. The method also includes modeling, using the corresponding altitude measurements, a modeled position of the foundation.

Abstract: An adjustable strap, detachably installed atop a mattress to serve as an aid for exercise, without having to alter the construction of the mattress or bed frame. The apparatus is utilized for sit-up exercise by an individual reclining upon the mattress. Each end of the strap forms a loop by means of a Velcro fastener of sufficient dimensions that the size of the loop can be varied. The loops are secured to the bed frame. A padded central portion is provided upon the strap, which is wide enough to accommodate a pair of ankles. Means are associated with the strap for spacing the strap from the mattress to provide a space into which the feet and ankles of the user can extend. A flat, semi rigid pad is provided, for the individual to sit atop the mattress without compressing the mattress during exercise.
