Abstract: This disclosure relates to macro- and micro-sized elastin-like polymers (ELP). The addition of a polyethyleneimine (PEI) block to the terminal end of ELP allows the particle radius as well as LCST to be controlled by changing any combination of polymer concentration, ion concentration, and pH. The addition of the PEI block also provides the ability to crosslink the copolymers and achieve a stable particle radius.

The system includes a deployment control system including controller logic having at least one processor and a memory storing instructions for implementing deployment and retraction of rear fences on a vehicle.

Abstract: An active spoiler for a vehicle including a fixed portion configured for attachment to the vehicle, an extendable portion configured for movement relative to the fixed portion, and a flexible portion secured between the fixed portion and the extendable portion. The spoiler has a retracted configuration and an extended configuration, whereby the flexible portion is stowed within the spoiler in the retracted configuration and the flexible portion is deployed in the extended configuration.

Abstract: Systems and methods for printing data on a substrate including a color-changeable material are provided. One system includes a processing circuit and a device including an energy source. At least a portion of a printed publication is printed on the substrate using a commercial printing press based on fixed data. The device including the energy source is configured to add variable data to the substrate. The processing circuit is configured to receive the variable data and to control the energy source to change a color of the color-changeable material based on the variable data to provide at least a portion of the printed publication. The processing circuit is configured to control the energy source to change the color of the color-changeable material in-line with a flow of the substrate through one of a printing line, a finishing line, or a packaging line of the commercial printing press.

Abstract: A stretchable fabric signal path may include a conductive strand located between first and second outer fabric layers. The outer fabric layers may be formed from intertwined strands of elastic material. The conductive strand may have a wavy shape to accommodate stretching of the stretchable fabric signal path. First and second inner fabric layers may be located between the outer stretchable fabric layers. The inner fabric layers may be formed from intertwined strands of non-elastic material. The inner fabric layers may have strands that are intertwined with the outer fabric layers to serve as anchor points for maintaining the shape of the conductive strand as the stretchable fabric signal path expands and contracts. The outer fabric layers and inner fabric layers may be woven. The conductive strand may convey electrical signals such as audio signals, power signals, data signals, or other suitable signals.

Abstract: A passively deployable solar panel array. A truss backing is attached to the back of the solar panels, and has top segments, bottom segments, and hinge linkages that form a series of moveable parallelograms operable to fold and unfold. The truss backing further has springs and trusses, with at least one spring and one truss associated with each of the parallelograms. The springs are operable to deploy the solar panels from a folded position to a deployed position. Each truss is operable to become in tension diagonally across its associated parallelogram once the solar panels are deployed into a final position.

Abstract: An active spoiler system for a vehicle is disclosed that changes from a stowed position to a deployed position. In the stowed position, one or more flexible sheets are stored on rollers inside the body of the vehicle. The flexible sheets are pulled outward out of the body of the vehicle by a rigid bar that rotates around a pivot, in response to a controller. The deployed active spoiler may decrease drag thereby increasing fuel efficiency, while also allowing for the active spoiler to be stowed when not needed due to road or weather conditions.

The stem is attached to an outside surface of a bowl and configured to support the bowl. The ultraviolet pattern is applied to an inside surface of the bowl. The ultraviolet pattern includes a center portion of a non-ultraviolet color, and alternating ultraviolet and non-ultraviolet concentric rings around the center portion.

Abstract: Telescoping boom systems, devices, and methods are provided in accordance with various embodiments. For example, some embodiments include zero dead band telescoping boom systems, devices, and methods. Embodiments in general include hard stop preloading mechanisms for telescoping booms with multiple tube segments. Some embodiments provide components that facilitate the deployment sequencing of the multiple tube segments along with facilitating preloading of the multiple tube segments of a telescoping boom. The tools and techniques provided may be integrated into the multiple tube segments rather than being provided as a separate system. Some embodiments allow for precise deployment of the multiple tube segments of the telescoping boom systems, devices, and methods.

Abstract: An adhesive application apparatus is provided. The apparatus uses a rolled on adhesive applied to a substrate. After roll application, an adhesive activator is sprayed onto the substrate. By spraying an activator onto the substrate after the adhesive is applied, the adhesive may be made tacky for adhesion, but the adhesive used for rolling may be highly stable and slow to dry/cure without said activator, which enhances rolled application effectiveness.

Abstract: A vibratory conveyor system includes a product transfer pan linked to a shaker base via spring arms. Vibration transferred from the shaker base to the spring arms causes the product transfer pan to oscillate and convey products across the product transfer pan. The product transfer pan has apertures defined therein, such that excess coatings on (or fallen from) the conveyed products tend to fall through the apertures. A chute situated beneath the apertures collects the fallen coatings, and preferably diverts it to a side of the conveyor for collection and subsequent reuse or disposal. The chute is preferably linked to the product transfer pan such that the chute and pan oscillate in tandem.

Abstract: Methods for the rapid elimination of carbon monoxide (CO) from CO-bound hemoglobin, myoglobin and cytochrome c oxidase in subjects with CO poisoning are described. The disclosed therapy involves the use of rationally designed, modified, regulator of CO metabolism (RcoM) proteins and pharmaceutical compositions thereof, which scavenge carbon monoxide from poisoned tissue. The recombinant RcoM compositions are infused into blood, where they rapidly sequester carbon monoxide and limit the toxic effects of carbon monoxide on cellular respiration, oxygen transport and oxygen utilization.
