Abstract: In an anti-biofouling context, an anti-biofouling system (20) is provided, which is configured to emit anti-biofouling light in an activated state thereof and to be applied to an object (10). Further, the anti-biofouling system (20) comprises a sensor system (30) that is configured to obtain measurement data relating to at least one structural feature of an anti-biofouling arrangement (1) including both the anti-biofouling system (20) and the object (10) in an actual case of the anti-biofouling system (20) being in place on the object (10). By having the sensor system (30) as mentioned in the anti-biofouling system (20), it is achieved that one or more structural aspects of the anti-biofouling arrangement (1) may be checked/monitored without a need for providing separate means for fulfilling such functionality.

Abstract: A method of producing artificial fossil coral which is an artistic replica of a natural coral reef formed from a slurry of cement, sand, ground PVC chips, colorant and water admixed with artistic rigid lightweight sponge or Styrofoam. Fiber glass strands are used to provide a plant like look to the artificial fossil coral and coloring of the artificial fossil coral duplicates the colors found in natural coral reefs.

Abstract: The instant invention is an improved cutter head with a salvageable end cap for hollow stem augers. The end cap includes a mechanism for retrieval upon completion of a drilling operation thereby allowing the end cap to include various bit formations so as to assist in the drilling operation. The side wall of the cutter head is modified to include a keyhole slot for maintaining of the end cap in a rigid position to prevent rotational movement.
