Abstract: Disclosed are methods and systems for monitoring a diesel generator system that includes a DPF filter in order to provide a highly efficient approach for monitoring the status of a DPF filter in order to determine if a regeneration is required. The methods and systems not only permit the ongoing determination of when a regeneration is appropriate in order to prevent excessive engine backpressure, but also accomplish this objective in a manner that reduces fuel consumption over the course of engine use.

Abstract: Releasable sinkers for marine applications are described, each of which utilizes rapidly disintegrating water soluble material as an attachment means or as part of an attachment assembly for securing a weight to fishing line. Depending on the configuration of the rapidly disintegrating water soluble material, after exposing the sinker to water, for example, by casting a line into the water or by returning a caught fish back into the water, the rapidly disintegrating water soluble material will dissolve, thereby releasing the sinker from the fishing line. The weighted portion of the sinker, which provides the majority of sinker weight, may be preferably formed from an organic material that will also eventually dissolve in water, although at a much slower rate than the rapidly disintegrating water soluble material.

Abstract: A detachable clamping sinker automatically detaches from fishing line after immersion in water. The sinker includes a first weighted half, and a second weighted half that is moveable relative to the first weighted half. An elastic tie assembly couples the first weighted half to the second weighted half. The elastic tie assembly includes an elastic member, and an externally exposed rapidly disintegrating water soluble material linking the elastic member to one of the weighted halves. The elastic member under tension imparts a force holding the first weighted half against the second weighted half to clamp a fishing line therebetween. The disintegrating material when dry withstands a casting load and when wet rapidly dissolves to release the tension that clamps the fishing line. The weighted halves may be biodegradable or dissolvable.

Abstract: A detachable sinker automatically detaches from fishing line after immersion in water. The sinker includes weight attachable to the line by means of a rapidly disintegrating water soluble material that when dry withstands a casting load and when wet rapidly dissolves. The weight may be biodegradable or dissolvable. The sinker may include a wildlife attractant released by the disintegrating material or by the dissolvable weight, may be rated according to time or depth at which the weight or attractant will release from the line, may display readable indicia corresponding to a weight value, a release time, or a depth, and may include an attachment means coupling the disintegrating material to the line, such as an elongated clamp for compressing the fishing line and the disintegrating material or a perforated attachment for threading the disintegrating material therethrough. The sinker may be an assembly including the detachable sinker and a fixed sinker.
