  • Energy harvesting from constrained buckling of piezoelectric beams
    Patent number: 10447177
    Abstract: An energy harvesting system for harvesting energy in response to application of an external force. The energy harvesting system comprises a beam member having a central member and at least one piezoelectric layer joined to the central member for deflection therewith. The beam member includes opposing first and second ends and is elastically deformable in response to application of the external force. A first mount couples the first end of the beam member and is generally stationary. A second mount couples the second end of the beam member. The second mount and the second end of the beam member are generally moveable in response to application of the external force between a first position and a second position, thereby outputting energy from the at least one piezoelectric layer in response to the movement from the first position to the second position.

  • Hold violation free scan chain and scanning mechanism for testing of synchronous digital VLSI circuits
    Patent number: 10447249
    Abstract: A sequential state element (SSE) is disclosed. In one embodiment, an SSE includes a differential sense flip flop (DSFF) and a completion detection circuit (CDC) operably associated with the DSFF. The DSFF is configured to generate a differential logical output. During a normal operational mode, the DSFF is synchronized by a clock signal to provide a differential logical output in a differential output state in accordance with a data input or in a precharge state based on the clock signal. The differential logical output is provided in a differential output state in accordance with a test input during a scan mode. The CDC is configured to generate a test enable input during the scan mode that indicates the scan mode once the differential logical output is in the differential output state. Accordingly, another SSE can be asynchronously triggered to operate in the scan mode without a separate scan clock.

  • Closed loop 3D printing
    Patent number: 10442118
    Abstract: To better control part quality of 3D printed parts, the temperature of an extruder filament using a secondary heat source is provided. A heat source, such as an infrared heat source, can be used to heat the filament of a 3D printer to the optimum temperature that will enhance welding of the filament to a substrate that it is being printed on or to. Such an optimum temperature can be based upon, in part, the temperature of the substrate. A controller or other intelligent control can be used to receive temperature readings of the substrate and/or filament and then can adjust the temperature of the heating source to optimize the temperature of the filament to better combine the filament to the substrate.

  • Starch spherulites having controlled enzymatic digestion
    Patent number: 10443080
    Abstract: Starch spherulites are produced by debranching of amylopectin-containing starch into short linear ?-1,4-linked glucans (e.g., short-chain amylose, SCA). The debranched linear glucans are directly converted into spherulites by heating the debranched starch mixture followed by cooling and crystallization to form well-developed spherulites. The spherulites exhibit controlled enzyme digestibility.

  • Hydrophilic, yet slippery solid surfaces
    Patent number: 10442166
    Abstract: In this work, a hydrophilic, yet slippery solid surface was developed. Because the surfaces are hydrophilic, there is significant affinity between the surface and contacting water, which results in substantial spreading of the contacting liquids on the surface. Due to their strong affinity, a high solid-liquid adhesion having virtually no mobility of the water on the surface occurs. However, counter-intuitively, the disclosed surfaces are highly slippery such that liquids can slide on the surface while maintaining their hydrophilicity. Demonstrated herein are water droplets that can slide on the surface under its own weight, when the hydrophilic, yet slippery solid surface is slightly tilted (?=3°). This indicates that the disclosed hydrophilic surfaces are slippery to water.

  • Controlled stimulation delivery from neurostimulator
    Patent number: 10441803
    Abstract: A system for providing neurostimulation includes an external device (“external exciter”) and an implanted device. The external exciter includes an energy source which inductively powers the implanted device. Examples of such external exciters include devices having at least one of: ultrasonic transducers, Radio Frequency (RF) transmitters, and solar cells. The implanted device includes circuitry that limits its maximum energy output to a predetermined saturation threshold such that excess stimulation from the external exciter does not raise the output of the implanted device beyond the saturation threshold. The output signal of the external exciter is then pulse-width modulated in order to produce a desired amount of output stimulation from the implanted device to stimulate the bioelectrically excitable tissue at a desired level.

  • Transmammary delivery of cyclooxygenase-2 inhibitors for analgesia in neonates
    Patent number: 10434083
    Abstract: Methods for transmammary administration of an analgesic to offspring swine are disclosed, which are useful for mitigating, inhibiting, and/or reducing pain in offspring swine prior to undergoing processing procedures that would cause or result in pain. The methods generally comprise administering, via injection, a cyclooxygenase-2 inhibitor class analgesic directly to a lactating female swine. The analgesic is passed indirectly to the offspring swine through the milk of the treated lactating female swine and has beneficial effects, including increases in weight gain, performance, and decreases in pain. A single dosage form injected into the lactating female is suitable for achieving indirect therapeutically effective levels of the cyclooxygenase-2 inhibitor class analgesic in the milk for the offspring.

  • Low temperature synthesis of aluminum hydr(oxide) inside porous media
    Patent number: 10435311
    Abstract: Preparing a porous hybrid media includes contacting porous media (e.g., strong base ion-exchange media) with an aqueous solution including aluminum ions to yield a aluminum-ion-containing porous media, contacting the aluminum-ion containing porous media with a reducing agent to impregnate elemental aluminum in the porous media, and oxidizing the elemental aluminum to yield a porous hybrid media including aluminum hydr(oxide) impregnated in the porous media. In some cases, a pH of an aqueous mixture including the aluminum-ion-containing porous media may be adjusted to form a floc including aluminum hydroxide, and the aluminum hydroxide-containing porous media may be contacted with a reducing agent to yield a porous hybrid media including aluminum hydr(oxide) impregnated in the porous media. The porous hybrid media may advantageously be prepared at low temperature (e.g., room temperature).

  • Multi-hypervisor virtual machines
    Patent number: 10437627
    Abstract: Standard nested virtualization allows a hypervisor to run other hypervisors as guests, i.e. a level-0 (L0) hypervisor can run multiple level-1 (L1) hypervisors, each of which can run multiple level-2 (L2) virtual machines (VMs), with each L2 VM is restricted to run on only one L1 hypervisor. Span provides a Multi-hypervisor VM in which a single VM can simultaneously run on multiple hypervisors, which permits a VM to benefit from different services provided by multiple hypervisors that co-exist on a single physical machine. Span allows (a) the memory footprint of the VM to be shared across two hypervisors, and (b) the responsibility for CPU and I/O scheduling to be distributed among the two hypervisors. Span VMs can achieve performance comparable to traditional (single-hypervisor) nested VMs for common benchmarks.
