Abstract: A non-powered impact recorder is disclosed. The non-powered impact recorder includes a resonator tuned for a resonant response within a predetermined frequency range. A reduced cross-sectional area portion is formed within the resonator and configured to structurally fail when the resonator experiences the resonant response. Additionally, the non-powered impact recorder includes an electric circuit element disposed about the reduced cross-sectional area portion of the resonator. Upon structural failure of the resonator, the electric circuit element is broken to cause a discontinuity in the electric circuit element. Interrogation of the discontinuous electric circuit element facilitates approximation of impact frequency and/or impact energy.

Abstract: Strain sensing may be provided. First, a strain threshold for a circuit board may be determined. Then a strain capacitor may be selected that will fail when the circuit board is subjected to the strain threshold while the strain capacitor is mounted on the circuit board. The strain capacitor may be ceramic and may be in a commercially available size. The strain capacitor may then be mounted to the circuit board and monitored for failure.

Abstract: Displacement occurring by external force between a first member (a case, for example) and a second member (an LCD holder, for example) facing the first member is applied to a detection body (an external force detector), and a loading history of the external force (fracture surfaces) is detected by deformation of the detection body occurring when the force exceeds an allowable limit. Provided are a body section and a force receiving section (a head, arms) projected from the body section. The body section is provided between the first member and the second member facing the first member and is supported by either first or second members. The force receiving section deforms when external force acting in the direction crossing a gap between the first and second members or in the direction along the gap exceeds the allowable limit.

Abstract: A method for customizing the fit of a saddle to a given horse and apparatuses thereof. The method comprises a step of inserting under a saddle disposed on the horse's back, a cushion pad previously shaped to uniformly distribute the pressure of the saddle on the horse. The method may further comprise a step of shaping the cushion pad by disposing on the horse's back an impression pad which contains a putty-like material to imprint the relief pattern of the pressure distribution of a saddle disposed on the horse's back. This is followed by setting the saddle on the impression pad, by riding the horse to imprint a relief pattern of the pressure distribution of the saddle on the impression pad, and by shaping the cushion pad by reproducing the relief pattern of the impression pad.

Abstract: Embodiments include a method for forming a glass which displays visible cracking prior to failure when subjected to predetermined stress level that is greater than a predetermined minimum stress level and less than a failure stress level. The method includes determining a critical flaw size in the glass and introducing a residual stress profile to the glass so that a plurality of visible cracks are formed prior to failure when the glass is subjected to a stress that is greater than the minimum stress level and lower than the critical stress. One method for forming the residual stress profile includes performing a first ion exchange so that a first plurality of ions of a first element in the glass are exchanged with a second plurality of ions of a second element that have a larger volume than the first ions. A second ion exchange is also performed so that a plurality of the second ions in the glass are exchanged back to ions of the first element.
