Abstract: Systems and methods for reducing erroneous weighing of items such as by detecting items extending beyond a periphery of a weigh platter whereby in one configuration, the system employs a light source disposed in or on a housing of a scanner-scale for producing a light beam along an edge of the weigh platter, the light beam being modulated to contain a defined packet of data; a detector for receiving the data-modulated light beam, the detector being disposed in or on the housing; and a processor coupled with the detector for decoding the defined packet of data responsive to the detector receiving the data-modulated light beam. Various indicators for alerting the operator of off-scale detection are also described.

Abstract: A method of spooling a marine pipeline (90) including a plurality of bi-metallic pipe sections (10) (66) onto a reel (60) including at least the steps of: (a) filling a first pipe section with a fluid (12); (b) spooling the first pipe section onto the reel; (c) filling a second pipe section with a fluid (78); (d) joining the first pipe section with the second pipe section wherein at least one of the first and second pipe sections maintains the fluid (12,78) therein; and (e) spooling the second pipe section onto the reel.

Abstract: Compositions and methods are disclosed for sealing subterranean spaces such as natural or induced fractures, vugs or annular spaces. The composition is composed of a base fluid consisting of a soluble alkali silicate, a gas generating additive, water, solids, and a setting agent. The gas generating additive may be coated or uncoated. The gas generating additive may also be in the form of a slurry. In the case of coated additives, the coating may act as a retarder or an accelerator to the expansion and setting agent of the soluble alkali silica. Similarly, the choice of carrier fluid in a slurry may retard or accelerate the expansion and setting of the alkali silicate-based plug.

In this way, the conventional need to overcome problems with welding a number of pre-formed 12 m or 24 m bi-metallic pipe stalks to form a 1 km bi-metallic pipe are avoided, thus also avoiding weaknesses that can be a part of conventional stalk-welding processes for forming an MLP.

Abstract: An apparatus and method are disclosed for tamper-proofing two-dimensional, optical, computer readable bar codes, including QR Codes. QR Codes, like traditional bar codes, contain computer readable content not cognizable by the human mind. The present invention teaches means of securing this content from would-be thieves and forgers motivated to overlay authorized, original content with unauthorized, replacement content.

Abstract: An improved greywater disposal system is provided which substantially eliminates onboard standing greywater. The system includes one or more onboard plumbing fixtures fluidly connected to a greywater sump. The bottom of the greywater sump is sloped toward a drain therein at a low end. The prongs of a sensor may be suspended in the sump drain and/or in an inlet chamber defined at an inlet end of the greywater sump. The sensor is associated with a controller and sump or bilge pump. The pump is turned on when the prong tips of the sensor become immersed in greywater which occurs substantially simultaneously with the production of the greywater. The onboard plumbing fixtures include one or more sinks, showers, bathtubs, washing machines and air conditioning units. The system may be used on boats, ships, RVs, campers or the like.

Abstract: A modified security protocol for remotely managed computer-based communications devices is presented. The protocol is based on the Syslog Sign protocol but is altered to allow an entity that collects log events from and/or remotely manages the device to provide authenticated acknowledgement of event logs that have been successfully received. This is achieved through an Acknowledgement Block which is signed by the entity and made available to the device.

Abstract: Methods of preventing flooding-type denial-of-service attacks in a computer-based network are described. Connection establishing messages known as SYN packets are matched with connection terminating messages (FIN packets) by using a hash algorithm. The hash algorithm or message digest uses source and destination IP addresses, port numbers, and a secret key as input parameters. The SYN packets and FIN packets are mapped to buckets using the hash algorithm and statistics are maintained for each bucket. A correspondence between SYN packets and FIN packets is maintained to close a security hole.

Abstract: Methods of detecting TCP SYN flooding attacks at a router located between a LAN and a network such as the Internet are described. The methods rely on a counting arrangement in which SYN and Fin packets are counted on both the LAN side and the network or Internet side of the router during a time interval. Weighting factors are applied to each count, the factor for the LAN side count having the opposite polarity to the factor for the network side count. The absolute values of the sums of the weighting factors of like polarity are equal. An abnormal number of unsuccessful connection attempts are determined based on a parameter calculated using the weighting factors in conjunction with the respective counts.
