  • Patent number: 6203443
    Abstract: A golf putter is provided having improved performance and custom adjustability. The putter has an adjustable-lie raised hosel which can be adjusted for a particular golfer, yet which may be semi-permanently fixed in position so that no adjustment can be readily made or worked loose during a round of golf play. To this end, the hosel has two members which are pivotally joined at a joint which includes a shaped sleeve mounted onto a projection attached to one hosel member and received in a shaped bore connected to the other hosel member. Rotation of the sleeve with respect to the projection and the bore results in an adjustment of the lie angle. Also, the putter has a sole sensor shaped to permit rocking on the ground in a lie-varying direction. Further, the putter includes a multiple replaceable and striking face plates for providing various lofts. Various weights are provided which attach to a rear of the selected face plate.

  • Patent number: 6079433
    Abstract: An automatic moisture sensing and watering system detects a moisture level within the soil. The automatic moisture sensing and watering system may be implemented in combination with a conventional automatic watering system to accurately control a moisture content of a plot of soil. Since a plant draws water directly from the soil, the automatic moisture sensing and watering system is adapted for controlling the moisture content of the soil itself, by measuring the moisture content within the soil. The watering period of an automatic watering system may be changed, based upon a detected moisture content within a plot of soil. Alternatively, an amount of water to be applied at a next watering period may be changed, based upon a detected moisture content within the plot of soil.

  • Patent number: 6066086
    Abstract: An automatic speed control system continually adjusts the speed of an implanted cardiac assist blood pump to an optimum level for the varying physiological needs of the patient. It does this by periodically iteratively incrementing the speed setpoint of the pump. When the system detects the imminence of a ventricular collapse at diastole, it decrements the speed setpoint by a predetermined safety margin. An alarm condition is provided if the setpoint decrease results in an insufficient blood flow rate through the pump. The flow rate and imminence of ventricular collapse are computed in real time as functions of only the pump's motor current and speed setpoint.

  • Patent number: 6055524
    Abstract: A model-free adaptive controller is disclosed, which uses a dynamic artificial neural network with a learning algorithm to control any single-variable or multivariable open-loop stable, controllable, and consistently direct-acting or reverse-acting industrial process without requiring any manual tuning, quantitative knowledge of the process, or process identifiers. The need for process knowledge is avoided by substituting 1 for the actual sensitivity function .differential.y(t)/.differential.u(t) of the process.

  • Patent number: 6050968
    Abstract: A softshell blood reservoir for heart-lung machines is symmetrical about a central vertical axis and is divided into two chambers: a small main chamber accessed by the blood inlet and outlet connectors, and a larger storage chamber accessed from the main chamber through a selectably closable passage. This arrangement greatly reduces the priming volume of the reservoir without substantially affecting its total capacity, and enhances the mixing of venous and cardiotomy blood.

  • Patent number: 6045752
    Abstract: Waterless temperature control of blood in a blood oxygenator is achieved by providing a non-disposable heater/cooler with a temperature-controlled surface that can be intimately mated with a heat-conducting surface of a disposable blood heat exchanger associated with the oxygenator. Blood flows in a shallow path past the heat-conducting surface so that substantially all of the blood will assume the temperature of the heat-conducting surface as it flows past that surface.

  • Patent number: 5980465
    Abstract: Physiological changes in a patient's circulatory system can be detected in real time during open heart surgery by injecting a known amount of a marker substance into the patient's blood prior to surgery, and during surgery continuously concurrently monitoring variations both of the quantity of circulatory fluid in the heart-lung machine's reservoir and of the marker substance concentration in the fluid being pumped through the heart-lung machine. The patient's blood volume can also be continuously computed from the data thus gathered.

  • Patent number: 5927099
    Abstract: Energy and water consumption of a commercial icemaker are greatly reduced by capturing the excess water running off the freezer plates and mixing it with new water to provide a pre-chilled water supply to the freezer plates. The resulting decrease in water demand makes practical the filtration of the new water by reverse osmosis to keep the recirculating water free of pathogens, and to reduce maintenance of the freezer plates by largely eliminating dissolved mineral contaminants from the new water.
