  • Publication number: 20060237036
    Abstract: A fill level control system for an article cleaning apparatus is provided. The fill level control system uses a sensor array to monitor a plurality of fill level points within, for example, a dishwasher. The level of water for each wash phase is monitored as a function of its height above the sump of an article cleaning apparatus, and the liquid used in the washing apparatus is introduced as a function of signals produced giving the level of liquid. The fill level control system further includes a low level sensor that turns the pumping system for the article cleaning apparatus off when the sump portion has been completely emptied. A further aspect of the fill level control system is an optional temperature control sensor, integrated with the liquid level sensors, to provide signals for modifying the temperature within the article cleaning apparatus.

  • Publication number: 20050043862
    Abstract: Automatic energy management is provided, in even the most complex multi-building system. The necessity of a human operator for managing energy in a complex, multi-building system is reduced and even eliminated. Computer-based monitoring and computer-based recognition of adverse energy events (such as the approach of a new energy peak) is highly advantageous in energy management. Immediate automatic querying of energy users within a system of buildings for energy curtailment possibilities is provided. Such immediate, automatic querying may be answered by the energy users through artificial intelligence and/or neural network technology provided to or programmed into the energy users, and the queried energy users may respond in real-time. Those real-time computerized responses with energy curtailment possibilities may be received automatically by a data processing facility, and processed in real-time.

  • Patent number: 6802426
    Abstract: In a releasable locking device, which is useful at a beam-to-column connection in a storage rack, a housing having a lateral wall with two parallel slots has an end wall at an outer end and is open at the inner end, a locking pin having an internal portion movable within and along the lateral wall is movable between a retracted position and an extended position, toward which the locking pin is biased, and an outer sleeve is movable outside and along the lateral wall of the housing and is connected to the locking pin via a connecting pin extending through the locking pin, through the parallel slots, at each end to the outer sleeve. The outer sleeve has an external flange to facilitate pulling of the outer sleeve to move the locking pin toward the retracted position.

  • Publication number: 20030132109
    Abstract: The present application is directed to pipette configurations, arrays of the same and methods for using such pipettes and arrays to accomplish electrical measurements, including whole cell and on cell measurements. In one aspect of the present invention, a pipette includes a hollow tubular section having a distal portion and a tip portion. A bubble is formed at the tip and includes an interior chamber in communication with the hollow tubular section at an end adjacent to the bubble portion. The bubble may have a diameter greater than the diameter of an adjacent portion of the hollow tubular section. An aperture is formed between the internal chamber and an exterior surface of the bubble to accommodate seal formation.

  • Patent number: 6472151
    Abstract: The present invention provides a method for generating and isolating cell lines that functionally express molecular targets for drug discovery without utilizing information from the nucleic acid or amino acid sequence of the target protein. This procedure for the first time allows one to develop fast, high throughput screens for evaluation of test compounds that may modulate molecular targets whose specific nucleic acid or amino acid sequences are unavailable.
