Abstract: Some embodiments relate to a vibration sensor. The vibration sensor comprises: a sensor base to couple to a vibration source; a piezoelectric transducer coupled on a first side of the transducer to the sensor base; at least one conductor coupled to the piezoelectric transducer; and a seismic weight positioned on a second side of the piezoelectric transducer; wherein the sensor base, the piezoelectric transducer and the seismic weight are aligned along an axis and arranged so that relative movement between the sensor base and the seismic weight arising from the vibration source causes a current to be generated in the piezoelectric transducer and an output signal corresponding to the generated current is detectable on the at least one conductor.

An AI (artificial intelligent) engine is coupled to the information data base. A knowledge base rule database is used for storing knowledge base rule and is coupled to the information database and the AI engine. A webpage generator is coupled to the knowledge base rule database and the AI engine. A user interface is coupled to the AI engine. A web server is coupled to the user interface and the webpage generator.

Abstract: Systems and methods for the management and organization of electronic records are disclosed. These systems and methods provide the user with capabilities such as inputting and retrieving documents, searching for documents and sharing documents across an organization. The systems and methods also allow the capture of unstructured electronic records not typically associated with document management systems like, for example, email or instant message conversations, allow for remote update of replicated data between electronic record management systems to ensure integrity and consistency of the electronic records, allow for structured replication of electronic records between remote and master systems, and provide a mechanism for rectifying multiple disposal rules that may apply to the same electronic record.

Abstract: A scraper for cleaning a lawn mower housing includes an L shaped blade element to conform to the underside of the housing. The blade element has a V shaped cross section to provide a concavity on the surface of the blade element facing the housing. The scraper dislodges debris collected within the housing by simple movement of the scraper around the periphery of the housing.
