Abstract: The present invention discloses a computer-implemented method for digitally signing transactions between multiple nodes comprising preparing a multi-party transaction block, comprising at least one transaction object comprising at least a goods transaction and a payment transaction, adding first digital asset sources, digital signing and transmitting the multi-party transaction block in the previous node, to a subsequent node, adding additional digital asset sources, digital signing and finally submitting the multi-party transaction block to a transaction ledger by the final node, wherein all of the digital asset sources to be swapped are recorded in the ledger. The present invention further discloses a system to accomplish the above, comprising a first node, a second node, and a transaction ledger. Further a computer program product including a program for a processing device, comprising software code portions for performing the steps of the above method is disclosed.

Abstract: A filtering device for reducing radiation, sediment, contamination, pollution, and erosion control contains a first flow plate, a second flow plate, a tubular portion, and a biodegradable filtering material. The first flow plate is terminally connected to a first end of the tubular portion. A plurality of openings of the first flow plate allows water to enter the tubular portion. The second flow plate is terminally connected to a second end of the tubular portion. A plurality of openings of the second flow plate allows water to exit the tubular portion. The biodegradable filtering material is integrated within the tubular portion so that water entering the tubular portion at the first end is filtered prior to exiting the tubular portion at the second end. Switchgrass is utilized as the biodegradable filtering material.

Abstract: A system and method for manufacturing erosion control filter socks consists of a mass of filtering material, a material supply assembly, an assembly section, and a packaging section. Switchgrass is used as the filtering material. Upon receiving the mass of filtering material, the material supply assembly appropriately transfers the filtering material to the assembly section. The filtering material is loaded into a receiving sock with the use of a sizing funnel in the assembly section to create a filter sock. The density of the filtering material within the filter sock varies. When loading is complete, the packaging section sizes the filter sock accordingly. When sizing the filter sock is complete, the filter sock is wrapped in a plastic cover so that the filter sock can be conveniently transported and installed.

Abstract: A biodegradable runoff filter is an apparatus that is used to filter silt, chemicals, and other contaminants out of water runoff produced at or near a work site. The apparatus includes a biodegradable filter sock, a botanical biomass filling, and a fastener. The biodegradable filter sock is a water-permeable container that is used to contain an amount of the botanical biomass filling. The biodegradable filter sock includes a lateral portion, an open end and a closed end. The lateral portion and the closed end surround the botanical biomass filling and contain it to a specific area. The open end of the biodegradable filter sock allows the botanical biomass filling to be packed into the biodegradable filter sock. The fastener fits over the open end and cinches the open end shut to prevent the botanical biomass filling from falling out of the biodegradable filter sock.

Abstract: The invention is a method of calling a group of tourists back to their conveyance, in which each passenger is given a portable alerting device when they leave the conveyance. When the conveyance is ready to leave, a transmitter on the conveyance transmits a wireless signal which causes the alerting device to vibrate or give off a light or sound signal, alerting the passenger to return to the conveyance for departure.

Abstract: A logical positioning mechanism is provided within a storage controller, thus enabling the storage controller to determine which logical position in a storage device is to be accessed next. The logical positioning mechanism includes one or more logical position indicators defined, maintained and controlled by the storage controller. The logical position indicators include the address of the logical position to be next accessed and are incremented and decremented by the storage controller depending upon the operation accessing the logical position.
