  • Publication number: 20240120047
    Abstract: A system receives medical data from multiple physiological monitor devices in various forms and formats. A data normalization process identifies each attribute type in the medical data reported by each device and assigns a unique attribute identifier. All parameters associated with an attribute are also identified and assigned a unique parameter identifier. The data normalization process uses this information to create a standardized data set for analysis. A rules processing engine applies alert and reporting rules to the standardized data set to generate a patient report and alerts for patient data that is beyond thresholds defined by the alert rules. The system provides default alert rules that may be overridden by clinic rule or manufacturer rules. Artificial intelligence (AI) principles may be applied using training set(s) of data to teach the rules processing engine to use the AI alert rules for data analysis.

  • Publication number: 20070012009
    Abstract: A method for controlling and modifying the drop rate of a header on an agricultural harvesting machine by providing a programmable electronic control unit capable of receiving operator input through an input device.

  • Publication number: 20070012012
    Abstract: An apparatus and method for calibrating the reel of an agricultural windrower, wherein a programmable control module in connection with a signal operated device in operative control of a variable displacement pump operable for controlling operation of the reel, is programmed as part of an automatic calibration routine for directing signals to the device having different values, for rotating the reel at two different speeds. The controller will then determine a characteristic algorithm or relationship between reel speed and signal value which will be predictive of reel speeds which will be achieved for a range of signal values.

  • Publication number: 20060254239
    Abstract: A system and method for managing the electrical control system of a header flotation and lift system of an agricultural harvesting machine, particularly one using only once fluid cylinder in connection with each respective side of the header, which system and method, in addition to executing header raise and lower commands, provides several automatically executable operating modes for the flotation and lift system, including a wake-up mode; a normal mode, which can include float; a charge accumulator mode; a transport mode; and a header remove mode, and the ability to seamlessly and easily transition between the modes.

  • Publication number: 20060144028
    Abstract: A hydraulic lift/flotation system for the header of a crop harvesting machine wherein each side of the header is supported by a single cylinder, which performs both the flotation and lift functions. For even lifting and flotation of an unbalanced header, each cylinder has its own control valve, pump, and accumulator. The operator sets the desired flotation force by actuating rocker switches; one switch position allows hydraulic oil to enter an accumulator to reduce header contact force with the ground. The other position allows oil to exit the accumulator to increase header contact force with the ground. To evenly float an unbalanced header, separate switches adjust each side independently. Once the flotation forces are set, the control valves will return to this preset flotation condition whenever float mode is selected, regardless of subsequent header lift and lower operations.

  • Publication number: 20060029095
    Abstract: A system and method of reducing the input and output pins used to interface a fast serial port Ethernet processing system using multiplexing. Using the system of the present invention, four pins can allow a plurality of Ethernet communication paths to be connected to a single processor on a substrate. These four connections include a clocking input as well as a strobe signal which coordinates the multiplexing and identifies the time period for a predetermined source. The physical layer and the processor are each provided with a multiplexor which is controlled by the strobe to select the network to be coupled at any given time. The multiplexor includes a counter which is incremented by the clocking input and reset by the strobe signal.

  • Patent number: 5591335
    Abstract: Filtration medium is formed of a mass of nonwoven melt blown support and filtration fibers which are integrally co-located with one another. The support fibers have, on average, relatively larger diameters as compared to the filtration fibers which are integrally co-located therewith. Preferably, the filtration medium is disposed within at least one annular zone of a filtration element, for example, a disposable cylindrical filter cartridge having an axially elongate central hollow passageway which is surrounded by the filtration media. A depth filter cartridge in accordance with the present invention may thus be formed having one or more additional filtration zones (which additional filtration zones may or may not respectively be provided with integrally co-located support fibers) in annular relationship to one another.

  • Patent number: 5499710
    Abstract: There is disclosed a one piece coin holder having a main flat body, a central obstruction and openings at both ends suitable for insertion or egress of a predetermined number of coins. The open ends define a cavity with a slightly larger diameter than said coin but flexible protrusions are configured at said open ends in such a manner so as to trap said coin per it's diameter. The afore mentioned cavities would also hold said coins in a flat manner employing tabs which extend inward from the upper edge of said cavity walls defining an aperture portion. Said cavities would have dimensions consistent with those needed to hold new coins or ones with worn diameters and/or thickness'. There are also alignment rails Incorporated along the under side to aid in the installation process.

  • Patent number: 4267953
    Abstract: A method is provided for alleviating the stress damage in metallic matrix composites, such as laminated sheet or foil composites, wherein non-intersecting discrete discontinuities are positively introduced into the interface between the layers so as to reduce the thermal stress produced by unequal expansion of the materials making up the composite. The discontinuities are preferably produced by drilling holes in the metallic matrix layer. However, a plurality of discrete elements may be used between the layers to carry out this purpose.

  • Patent number: 4211354
    Abstract: A method is provided for alleviating the stress damage in metallic matrix composites, such as laminated sheet or foil composites, wherein discontinuities are positively introduced into the interface between the layers so as to reduce the thermal stress produced by unequal expansion of the materials making up the composite. Although a plurality of discrete elements could be used to form one of the layers and thus carry out this purpose, the discontinuities are preferably produced by simply drilling holes in the metallic matrix layer or by forming grooves in a grid pattern in this layer.
