| Disclosed herein are systems, methods, and computer-readable storage media for gravity-driven pumps, gravity-driven power generators that power electric pumps, as well as various supporting concepts, mechanisms, and approaches. As a tire rotates around an axle, the pull of gravity varies for a given point on the tire. While gravity is always pulling ‘down’, the force relative to a fixed point on the tire changes. Gravity-driven pumps exploit these changes in gravitational force to do work. Automatic, gravity-driven pumps can be used to inflate tires to offset the natural gas leakage of modern tires, and can maintain tire pressure and inflation within a desired or optimal range. As different conditions are met, pump parameters are determined which can adjust the pumps. Such conditions include driving patterns, load, and temperature, and resulting adjustments include turning on and off pumps, varying stroke length, and varying the number of strokes required. | ||||||

| 80 | Strain-Responsive Visual Indicator | US12088990 | 2006-10-02 | US20080264327A1 | 2008-10-30 | Martin Andrew Pett; Ian Andrew Jamieson |
| A strain-responsive visual indicator comprises a pair of overlapping shutter strips (1, 2) adapted to be mounted to a substrate such that strain in the substrate causes relative movement M between them. Each shutter strip comprises an alternating set of windows (5) or (6) and bars (7) or (8) and the distal strip (2) is backed by a strip (3) of a different colour exposed through its windows (6), or the distal strip can instead be printed with a set of alternating colours in place of its windows and bars. The effect is that under different strain conditions different colour indications from the distal strip (2) will be visible through the windows (5) of the proximal strip (1), in accordance with the relative positions of the two strips. The indicator can be incorporated e.g. in the shaft of a toothbrush to give a visual warning in response to flexure of the shaft if excessive brushing pressure is applied. Numerous other applications and the use of different types of indicia are indicated in the specification. | ||||||
