摘要:
A cementitious armor panel assembly including cementitious armor panel with ballistic and blast resistant properties attached to a frame structure to produce a protective structure. The cementitious armor panels have a continuous phase resulting from the curing of an aqueous mixture of an inorganic cement binder, an inorganic mineral filler having a particle size of about 150-450 microns, a pozzolanic mineral filler, a polycarboxylate based superplasticizer self-leveling agent, and water. The mixture may also contain alkanolamine, and acid or acid salt. Prior to curing, the continuous phase is reinforced with fiber uniformly distributed in the continuous phase before it is cured to form the panel. The panel may be reinforced with a skin attached to at least one surface of the panel.

A process for simultaneously measuring the velocity of terahertz electromagnetic radiation in a dielectric material sample without prior knowledge of the thickness of the sample and for measuring the thickness of a material sample using terahertz electromagnetic radiation in a material sample without prior knowledge of the velocity of the terahertz electromagnetic radiation in the sample is disclosed and claimed. The process evaluates, in a plurality of locations, the sample for microstructural variations and for thickness variations and maps the microstructural and thickness variations by location. A thin sheet of dielectric material may be used on top of the sample to create a dielectric mismatch. The approximate focal point of the radiation source (transceiver) is initially determined for good measurements.

A cementitious panel with ballistic and blast resistant properties having a core layer of ultra-high compressive strength composite and at least one skin layer. The panels can also be used in walls, ceiling and flooring panels which require high compressive strength for resistance to earthquakes and surfaces resistant to surface abuse such as in prison and other institutions. The panel core layer has a continuous cementitious phase resulting from the curing of an aqueous mixture, in the absence of silica flour, of inorganic cement binder, inorganic mineral filler having a particle size of about 150-450 microns, a pozzolanic mineral filler, polycarboxylate based superplasticizer, alkanolamine and acid or alkali metal acid salt; and water. The mixture may be uniformly reinforced with fiber added before curing. The cementitious core layer is then reinforced with the skin, such as fiber reinforced polymer, attached to at least one panel surface.

A semi-rigid transparent shield for a jogging stroller provides occupant protection from wind, rain and snow. The device quickly and easily attaches to, and detaches from a jogging stroller. The semi-rigid transparent shield does not crease or wrinkle, maintaining excellent visibility for stroller occupant. The shield also provides protection from air borne road debris caused by passing vehicles. The shield pivots for easy loading and unloading the jogging stroller. The shield is under compression to add resistance to external forces. A sheet assembly attaches to a frame assembly forming a geometric arch adding stability and resistance to external forces. A method to provide protection of a child in a jogging stroller by shielding the child with a material that does not wrinkle or crease is also contemplated. The occupant space is substantially sealed from the outdoor elements. A method of shielding a child in a jogging stroller by flexing a sheet assembly of a semi-rigid material into a frame assembly is also disclosed. Further, the shield is flexed in the mounting hardware.

An ad hoc method is provided for synchronizing a wireless network. The method involves broadcasting a first signal including a join message from a first node (FN). The method also involves saving a first timestamps in a memory device internal to the FN after broadcasting the first signal. The method further involves generating a signal including a join response message after receiving the first signal. The join response message is comprised of a second timestamp indicating a local time during which the first signal was received at the second node (SN). The method also includes the step of determining an initial time offset by computing a difference between the first timestamp and the second timestamp. The method further includes the steps of generating a request to send (RTS) message at the FN. The FN uses the initial time offset in conjunction with the RTS message to asynchronously communicate with the SN.

A system for managing assets, and facilitating electronic commerce respecting the assets includes a computerized database for storing asset profiles for a plurality of assets. The asset profiles, each include an asset specification and a bid definition. The asset specification includes maintenance history data for the asset and the bid definition outlines the bounds for one of sale, rental or lease of the asset. Users of the system may search the database remotely over the Internet for desired assets, and retrieve detailed information, such as maintenance history, and then bid on the asset for purchase, rental, or lease. Users can also add their own assets to the database for search by others. The system also includes a fantasy fleet feature for conducting “what if” analyses of a simulated fleet containing existing assets and proposed assets.
摘要:
A device (or system) and method for sorting or sequencing product in different bundles. The device includes a staging area for separating a first plurality of bundles having a first product type and a second plurality of bundles having a second product type. A sorting mechanism sorts the separated first product type with the second product type to a predetermined sort level. A product bundle mechanism forms a plurality of bundles with sorted product comprising the first product type and the second product type. A bundle sorter sorts the plurality of bundles exiting from the product bundle mechanism and directs each bundle of the plurality of bundles to a pallet building area associated with a destination of the predetermined sort level.
