  • Patent number: 10204864
    Abstract: The present invention provides stretchable, and optionally printable, semiconductors and electronic circuits capable of providing good performance when stretched, compressed, flexed or otherwise deformed. Stretchable semiconductors and electronic circuits of the present invention preferred for some applications are flexible, in addition to being stretchable, and thus are capable of significant elongation, flexing, bending or other deformation along one or more axes. Further, stretchable semiconductors and electronic circuits of the present invention may be adapted to a wide range of device configurations to provide fully flexible electronic and optoelectronic devices.

  • Patent number: 10189243
    Abstract: In a method of printing a transferable component, a stamp including an elastomeric post having three-dimensional relief features protruding from a surface thereof is pressed against a component on a donor substrate with a first pressure that is sufficient to mechanically deform the relief features and a region of the post between the relief features to contact the component over a first contact area. The stamp is retracted from the donor substrate such that the component is adhered to the stamp. The stamp including the component adhered thereto is pressed against a receiving substrate with a second pressure that is less than the first pressure to contact the component over a second contact area that is smaller than the first contact area. The stamp is then retracted from the receiving substrate to delaminate the component from the stamp and print the component onto the receiving substrate. Related apparatus and stamps are also discussed.

  • Patent number: 10192830
    Abstract: The present invention provides electronic circuits, devices and device components including one or more stretchable components, such as stretchable electrical interconnects, electrodes and/or semiconductor components. Stretchability of some of the present systems is achieved via a materials level integration of stretchable metallic or semiconducting structures with soft, elastomeric materials in a configuration allowing for elastic deformations to occur in a repeatable and well-defined way. The stretchable device geometries and hard-soft materials integration approaches of the invention provide a combination of advance electronic function and compliant mechanics supporting a broad range of device applications including sensing, actuation, power storage and communications.

  • Patent number: 10186333
    Abstract: A traveling wave nuclear fission reactor, fuel assembly, and a method of controlling burnup therein. In a traveling wave nuclear fission reactor, a nuclear fission reactor fuel assembly comprises a plurality of nuclear fission fuel rods that are exposed to a deflagration wave burnfront that, in turn, travels through the fuel rods. The excess reactivity is controlled by a plurality of movable neutron absorber structures that are selectively inserted into and withdrawn from the fuel assembly in order to control the excess reactivity and thus the location, speed and shape of the burnfront. Controlling location, speed and shape of the burnfront manages neutron fluence seen by fuel assembly structural materials in order to reduce risk of temperature and irradiation damage to the structural materials.

  • Publication number: 20190018746
    Abstract: A method of transferring memory from an active to a standby memory in an FT Server system. The method includes the steps of: reserving a portion of memory using BIOS; loading and initializing an FT Kernel Mode Driver; loading and initializing an FT Virtual Machine Manager (FTVMM) including the Second Level Address Translation table SLAT into the reserved memory. In another embodiment, the method includes tracking memory accesses using the FTVMM's SLAT in Reserved Memory and tracking “L2” Guest memory accesses by tracking the current Guest's SLAT and intercepting the Hypervisor's writes to the SLAT. In yet another embodiment, the method includes entering Brownout by collecting the D-Bits; invalidating the processor's cached SLAT translation entries, and copying the dirtied pages from the active memory to memory in the second Subsystem. In one embodiment, the method includes entering Blackout and moving the final dirty pages from active to the mirror memory.

  • Patent number: 10181483
    Abstract: A method of printing transferable components includes pressing a stamp including at least one transferable semiconductor component thereon on a target substrate such that the at least one transferable component and a surface of the target substrate contact opposite surfaces of a conductive eutectic layer. During pressing of the stamp on the target substrate, the at least one transferable component is exposed to electromagnetic radiation that is directed through the transfer stamp to reflow the eutectic layer. The stamp is then separated from the target substrate to delaminate the at least one transferable component from the stamp and print the at least one transferable component onto the surface of the target substrate. Related systems and methods are also discussed.

  • Publication number: 20180355798
    Abstract: A gas turbine having an annular flowpath defined between concentric inner radial and outer radial boundaries. A plenum is positioned just outboard of the outer radial boundary that wraps circumferentially in spaced relation thereto. The height of the plenum is defined radially between a floor and ceiling. The plenum includes an inlet formed through the ceiling at a first end and spaced outlet ports formed through the floor. The plenum includes a divider baffle that spans the width of the plenum and extends between the first end and the second end of the plenum so to divide the plenum into radially stacked first and second compartments. The first compartment connects directly to the inlet, while the second compartment connects directly to the outlet ports. The height of the first compartment tapers between a greater height at the first end and a lesser height at the second end of the plenum.

  • Patent number: 10137306
    Abstract: Materials and systems that enable high efficiency conversion of mechanical stress to electrical energy and methods of use thereof are described herein. The materials and systems are preferably used to provide power to medical devices implanted inside or used outside of a patient's body. For medical devices, the materials and systems convert electrical energy from the natural contractile and relaxation motion of a portion of a patient's body, such as the heart, lung and diaphragm, or via motion of body materials or fluids such as air, blood, urine, or stool. The materials and systems are capable of being bent, folded or otherwise stressed without fracturing and include piezoelectric materials on a flexible substrate. The materials and systems are preferably fashioned to be generally conformal with intimate apposition to complex surface topographies.

  • Publication number: 20180303418
    Abstract: Disclosed are appendage mountable electronic systems and related methods for covering and conforming to an appendage surface. A flexible or stretchable substrate has an inner surface for receiving an appendage, including an appendage having a curved surface, and an opposed outer surface that is accessible to external surfaces. A stretchable or flexible electronic device is supported by the substrate inner and/or outer surface, depending on the application of interest. The electronic device in combination with the substrate provides a net bending stiffness to facilitate conformal contact between the inner surface and a surface of the appendage provided within the enclosure. In an aspect, the system is capable of surface flipping without adversely impacting electronic device functionality, such as electronic devices comprising arrays of sensors, actuators, or both sensors and actuators.

  • Publication number: 20180300775
    Abstract: Systems and methods provide a real time cash incentive to a user for purchasing merchandise via a web-based portal. The method includes receiving a product definition and a personal credential from the user, and periodically retrieving price quotes for the defined product from a plurality of retail sites. The plurality of retail sites are partitioned into groups based on a confidence level assigned to each site. A fair market value (FMV) is calculated for the defined product by applying a weighted algorithm to the retrieved price quotes within each of the groups. Using the web-based portal, the calculated FMV of the defined product is displayed with a plurality of links to a subset of the retail sites having price quotes within a predetermined range of the FMV.
