A microspring includes a film stack having a base disposed on a build plane and a spring member extending from the base. The film stack includes a compressive layer, a substantially stress-free layer, and a tensile layer. The film stack is formed of one or more materials that become superconducting below 140 K. A stress gradient in the film stack causes the spring member to curl away from the build plane of the base.

A method of manufacturing superconductor structures includes depositing a release film on a substrate, forming a stack of films comprising an elastic material and a superconductor film, releasing a portion of the elastic material by selective removal of the release film so that portion lifts out of the substrate plane to form elastic springs. A method of manufacturing superconductor structures includes depositing a release film on a substrate, forming a stack of films comprising at least an elastic material, releasing a portion of the elastic material so that portion lifts out of a plane of the substrate to form elastic springs, and coating the elastic springs with a superconductor film.

An apparatus comprises a frangible structure coupled or integral to at least a portion of the apparatus and a triggerable mechanism disposed at or proximate the frangible structure. The triggerable mechanism is configured to break the frangible structure in response to a trigger signal. A containment structure is disposed on or over at least a portion of the frangible structure. The containment structure is configured to allow at least the portion of the frangible structure to deform or change shape in response to breaking of the frangible structure while keeping substantially all fragments of at least the portion of the broken frangible structure together.

A computer adapted to convert images into raw data can provide the raw data to a control interface adapted to transmit the raw data with timing information to an electronic driver circuit. The electronic driver circuit can convert the raw data with the timing information provided by a control interface into regulated current signals provided to the semiconductor laser array at 300 dpi and higher. The semiconductor array can convert the current signals into light to illuminate an imaging member. The laser array can comprise vertical cavity surface emitting lasers providing imaging greater than 300 dpi. Each semiconductor laser can operate at 50 mW or greater.

An apparatus includes a structure comprising a predetermined breakable region and a mechanical actuator disposed at or proximate the predetermined breakable region. The mechanical actuator comprises an impact member coupled to a spring arrangement, and a restraint member operably coupled to the spring arrangement. A trigger source is operably coupled to an electrical power source. The trigger source, in response to receiving current from the electrical power source, is configured to release or break the restraint member so as to allow the spring arrangement to forcibly move the impact member into contact with, and break, the predetermined breakable region.

An electronic assembly and methods of making the assembly are disclosed. The electronic assembly includes a substrate with an elastic member having an intrinsic stress profile. The elastic member has an anchor portion on the surface of the substrate; and a free end biased away from the substrate via the intrinsic stress profile to form an out of plane structure. The substrate includes one or more spacers on the substrate. The electronic assembly includes a chip comprising contact pads. The out of plane structure on the substrate touches corresponding contact pads on the chip, and the spacers on the substrate touch the chip forming a gap between the substrate and the chip.

A self-destructing device includes a frangible substrate having at least one pre-weakened area. A heater is thermally coupled to the frangible substrate proximate to or at the pre-weakened area. When activated, the heater generates heat sufficient to initiate self-destruction of the frangible substrate by fractures that propagate from the pre-weakened area and cause the frangible substrate to break into many pieces.
