Abstract: An environmental sensing device includes an interferometric modulator which permanently actuates, in a visually-detectable manner, in response to being exposed to a predetermined environmental threshold or condition. The device can include a reactive layer, coating, or proof mass disposed on a movable member of the interferometric modulator. The reactive layer, coating, or proof mass can expand, contract, bend, or otherwise move when exposed to a predefined chemical, level of humidity, temperature threshold, type of radiation, and/or level of mechanical shock, causing the interferometric modulator to collapse and permanently indicate such exposure.

Abstract: A pressure measurement method using a pressure measuring film in which a toner layer with a definite thickness is held between an adhesive layer formed on a first support and an inactive adhesive layer formed on a second support. Prior to applying the pressure to be measured to the measuring film, the inactive adhesive layer is activated to have an adhesive property. After pressure to be measured is applied to the film, the first support is removed and the applied pressure is determined based on the amount of toner attached to the second support. Using a toner having extremely small size, an extremely low pressure applied to an extremely small contact area can be measured. Also the pressure measuring film is not affected by use conditions (temperature, humidity). The inactive adhesive layer may be formed of a thermoplastic resin adhesive which can be activated by heating to become adhesive.

Abstract: A film is placed between contacting surfaces in an assembly. The film has an optical property responsive to pressure. A compressive force is applied to the contacting surfaces to generate an initial pressure pattern. The film is removed from between the contacting surfaces. The optical property is sensed to derive a sensed initial pressure pattern. A stored setting controls the compressive force. The sensed initial pressure pattern is compared to a reference pressure pattern. The stored setting is updated to adjust the compressive force as a function of the comparing.
