Abstract: A seating arrangement includes a base, a seat assembly operably coupled to the base, and a back assembly that includes a substantially rigid back frame including a pair of side portions spaced from one another and extending upward from the base, and a substantially flexible back shell including a front surface and a rear surface opposite the front surface, a plurality of laterally-extending slots that extend between the front surface and the rear surface and that cooperate to define a plurality of laterally-extending ribs therebetween, where a pair of laterally-extending ribs of the plurality of laterally-extending ribs are connected to one another via a vertically-extending rib located at a substantial midpoint across a width of the back shell, and wherein the back shell is coupled to each of the side portions of the back frame at locations above the plurality of laterally-extending slots.

Abstract: A dry papercrete mix containing a pulp of fiber material such as newsprint and sharp sand, Portland cement and adding additional sand and/or pumice. The resulting dry, granular mix can then be handled stored and used in the manner which is conventional for concrete. The dry papercrete mix can be fortified with a fiber form of basalt which can be added to or substituted for all or a portion of the cellulose fiber content of the dry papercrete mix to provide a stronger structure when hydrated and cast into a desired shape with only a small increase in weight. Basalt reinforcing bars and meshes may be included in shapes cast from the hydrated mix in combination with or substitution for steel reinforcing structures. Including basalt in the mix and in reinforcing systems allows the design of joints between structural modules to provide exceptional strength in a unitary structure so formed.

Abstract: A dry papercrete mix is formed by preparing a wet pulp of fiber material such as newsprint and sharp sand by mixing sand, fiber material and water in a batch or continuous mixer, drying the pulp to a moisture content below that which will cause a reaction with Portland cement and adding additional sand and/or pumice and Portland cement. The resulting dry mix can then be handled, stored and used in the manner which is conventional for concrete. The dry papercrete mix can also be applied by pouring the dry papercrete mix into a form in a dry state and injecting water into the dry mix until the mix is sufficiently wetted without mixing in the manner common for concrete. Structural modules and a technique for joining them into a structure are particularly appropriate to the use of dry application papercrete.

Abstract: A street sign assembly is provided wherein the panels are illuminated. Two street signs, substantially perpendicularly to one another mounted on a pole near an intersection of two streets, are backlit on both sides to make them visible readable at night. Low power consumption light emitting diodes (LEDs) are used to illuminate the signs and are mounted internal to the sign housing such that the street name is backlit from within the housing, making it more readable from a distance at night. The LEDs are mounted between the two opposed faces of a housing so that their light is used to illuminate both faces. Translucent opposed frosted plates are positioned within the housing to reflect the LED lights and to prevent the mirror images on the two opposed faces from being visible from the other side. The power for the LEDs is provided by rechargeable DC batteries. A solar panel and a DC generator coupled to a wind turbine are installed on the post and are wired to provide charge current to the DC batteries.

Abstract: A IP telephony service allows customers to form user groups. Each user group can include multiple members, each of whom have their own telephony device. When a member of a user group sends a messages to another member of the user group, the message is posted to a group message board so that all members of the group can view the message. This could include sending information to each of the telephony devices for all members of the group so that each telephony device could display the message on a display screen. The displayed messages could also indicate who sent each message and to whom each message was directed. As a result, each member of the group can view messages passing back and forth between all members of the group.

Abstract: Non-invasive methods for detecting arterial disease in vivo include obtaining acoustic signals from a sensor held on an external body region proximate an artery. A complex frequency grid of frequencies and associated lifetimes of the obtained acoustic signals is generated. A predictive model of complex frequencies associated with peak-perturbation acoustic signals attributed to boundary perturbations in vivo that occur with early stage arterial disease is provided. A predictive model of complex frequencies associated with line-perturbation acoustic signals attributed to boundary perturbations in vivo that occur with later stage arterial disease and thickening of arterial junctions is also provided. It is determined whether peak and/or line-perturbation acoustic signals of the predictive models are present to detect whether the subject has arterial disease.
