An automobile interior trim component includes a molded substrate laminated onto a cover sheet including a foam backing and a skin film having a surface texture. The cover sheet is preheated so the skin film is in a melted viscous liquid state above its melting temperature, and the foam backing remains in a solid elastic foam state below its melting temperature. The preheated cover sheet is mechanically pre-molded by a back mold into a front mold. Pressurized air is applied through the back mold, to blow-mold the cover sheet against the front mold, so the melted skin film reproduces a surface texture of the front mold surface while the solid foam backing acts as a buffer and air barrier layer. Vacuum is applied through the front mold surface. The mold is opened, a substrate is introduced, and the back mold then molds and thermally laminates the substrate against the foam backing of the cover sheet.

An energy dissipative element (24) protects hard disk drives (22, 72, 92) from shocks and vibrations. A closed elastic envelope (48) houses a body of open cell foam (54), a volume of viscous liquid (56), and a compressible gas (64). Under compression or expansion of the foam (54), viscous liquid (56) flows through cell orifices and thereby dissipates energy resulting from external force applied against the elastic wall (48). The energy dissipative elements (24) are applied between a disk drive housing (22) and an outer case (26) to create a ruggedized portable disk drive module (20).

A piezoelectric cantilever with a non-piezoelectric, or piezoelectric tip useful as mass and viscosity sensors. The change in the cantilever mass can be accurately quantified by monitoring a resonance frequency shift of the cantilever. For bio-detection, antibodies or other specific receptors of target antigens may be immobilized on the cantilever surface, preferably on the non-piezoelectric tip. For chemical detection, high surface-area selective absorbent materials are coated on the cantilever tip. Binding of the target antigens or analytes to the cantilever surface increases the cantilever mass. Detection of target antigens or analytes is achieved by monitoring the cantilever's resonance frequency and determining the resonance frequency shift that is due to the mass of the adsorbed target antigens on the cantilever surface. The use of a piezoelectric unimorph cantilever allows both electrical actuation and electrical sensing. Incorporating a non-piezoelectric tip (14) enhances the sensitivity of the sensor. In addition, the piezoelectric cantilever can withstand damping in highly viscous liquids and can be used as a viscosity sensor in wide viscosity range.

A temperature-activatable time-temperature indicator that can be used to monitor the historical exposure of a host product to ambient temperatures includes an optically readable, thermally sensitive indicator element. The indicator element can be inactive below a base temperature and is intrinsically thermally responsive at or above an activation temperature which is equal to or greater than the base temperature. The indicator can record cumulative ambient temperature exposure above the activation temperature irreversibly with respect to time. The indicator element can include a synthetic polymeric material, and optionally, a dye. A side-chain crystallizable polymer such as poly(hexadecylmethacrylate), that is solid below the base temperature and is a viscous liquid above the activation temperature can be employed. Intense indicator element colors can be obtained using an appropriate dye or dyes. Various structural configurations of indicator are described and illustrated.

A method of assembling electronic components using a dispenser having a nozzle in fluid communication with a source of viscous liquid having a high surface tension and having an air discharge passage in fluid communication with a source of pressurized air. A droplet of the viscous liquid is dispensed from the nozzle onto a printed circuit board to form an initial contact area between the droplet and the printed circuit board and the high surface tension of the droplet causes the initial contact area to remain substantially constant. A burst of air is then discharged from the air discharge passage for impinging the droplet after the droplet contacts the printed circuit board, which increases the initial contact area between the droplet and the printed circuit board.
