  • Patent number: 6802084
    Abstract: A leak detection and reporting system for detecting and reporting different types of leaks. Different alarms are activated in response to different types of leaks. The present invention includes a timing module and a water flow sensor. The timing module measures a standard fill time required to properly fill a reservoir. A lower time threshold and an upper time threshold are then calculated based upon the standard fill time. A first alarm may be activated if a subsequent fill time is below the lower time threshold to identify a small leak. Also, a second alarm may be activated if a subsequent fill time is above the upper time threshold to identify a larger leak.

  • Patent number: 6558352
    Abstract: A system and method for automatically controlling the quantitative delivery of, and then recording the occurrence of the administration of medicines to animals is disclosed and claimed. An intelligent syringe receives and automatically implements an instruction relating to a preferred quantity of medicine to be delivered to a specific animal, based on the measured weight of the animal. Upon actuation of the intelligent syringe, a first signal containing information relating to the actuation of the intelligent syringe, and the resulting injection of the animal is transmitted to a data repository. An EID is attached to the animal to provide a tamper-resistant electronic identification of the animal, and a receiver is utilized for receiving the first signal from the intelligent syringe and the electronic identification of the animal. Thereafter, a computer database maintains the information contained in the first signal for selective access and analysis.

Each base color is associated with a complementary color representation, a pair of split complementary color representations, and a pair of triadic match color representations. The complementary color representation, each split complementary color representation, and each triadic match color representation are associated with a quality such as a personality trait or mood. Each color representation, including the base color, is divided into a spectrum of colors based upon hue. Each color of the spectrum of the base color may be matched with the colors in the spectrums of the complementary color representation, the pair of split complementary color representations, and the pair of triadic match color representations based upon a desire for one of the qualities.

  • Patent number: 6519907
    Abstract: Modular construction elements are produced by assembling cross posts and longitudinal posts to form a frame of exact specification having a void between the assembled posts. Planks are affixed to the assembled posts and an insulation medium may be located within the void to enhance performance of the elements. The modular construction elements are interconnected by interposing a joiner therebetween. The joiner has a receptacle casing, a round bolt and a screw structure. When the screw structure is in place and initially engaged with the modular construction elements, it is actuated to urge the elements together in a desirable fashion.
