  • Publication number: 20240039654
    Abstract: A dual antiphase read-head arranged card reader is provided. The card reader includes a first read-head arrangement and a second read-head arrangement. Electromagnetic noise is applied to both the first and second arrangements. Waves associated with the electromagnetic noise on the second arrangement is transformed and applied to the first arrangement canceling the noise on a first read head of the first arrangement. The first read head reads magnetically encoded information on a magnetic strip of a card inserted into a card slot of the card reader free of noise. However, the noise remains present such that any skimmer read head of a skimmer inserted into the card slot is unable to read the magnetically encoded information off the magnetic strip of the card.

  • Publication number: 20230027114
    Abstract: The present disclosure relates to a system and method for recognizing objects used in a medical procedure using a convolutional neural network. No database of image information for such objects is used or required. Rather, the neural network is trained to recognize the objects, and does not require any such image database. The system is able to reconcile the recognized objects against a ‘counted-in’ list of objects for the procedure, to ensure that all such objects are accounted for prior to closing the procedure.

  • Patent number: 5931160
    Abstract: A ventilator control system controls a ventilator pneumatic system in a medical ventilator. The ventilator control system includes a user interface, a memory and a processor. The user interface receives input values from a user for setting one or more breath parameters within a set of breath parameters. The user interface can include a display for displaying the status of the patient's pulmonary system and the set of breath parameters. The memory stores the set of breath parameters after the user has set one or more breath parameters to desired input values. The processor simultaneously adjusts a plurality of controls within a ventilator pneumatic system in response to the set of breath parameters. The user can change or implement new phases, breaths, modes or therapies in seconds such that the therapy delivered to the patient is essentially uninterrupted. Also, a simulator may be provided for predicting the status of the patient's pulmonary system prior to adjusting the plurality of controls.

  • Patent number: 4624193
    Abstract: An improved method and apparatus for the jet injection of agricultural liquids into the soil includes a series of jet nozzles, one for each plant row, spaced along the usual tool bar carried by a tractor which normally tows a nurse tank containing the liquid. A pump having an adjustable delivery rate is driven at a rate proportional to ground speed of the tractor, normally by the power take-off of the tractor, to deliver liquid from the nurse tank under substantially constant high pressure. A timing distributor, also driven by the power take-off, connects the high pressure liquid, i.e. the pump output, successively to the nozzles so that the entire output of the pump is concentrated through one nozzle at a time, for a very brief interval, to inject a high velocity slug of liquid which will penetrate the soil to an agronomically satisfactory depth. The timing is such that one slug is injected for each nozzle during a predetermined distance of travel, e.g.

  • Patent number: 4519542
    Abstract: A spray type applicator for liquid agricultural chemicals has no boom but uses only a cluster of nozzles which emit sprays to create narrow ground-impacting overlapping patterns extending laterally of the carrying vehicle. Swath width of the overall pattern is maintained substantially constant by automatically adjusting the above-ground height of those nozzles which throw laterally outwardly of the vehicle in accordance with nozzle pressure which is varied to vary application rate. Others of the nozzles, which direct their sprays downwardly, are fixed to the vehicle because the swath width of their ground-impacting spray patterns will not change appreciably with changes in nozzle pressure.

  • Patent number: 4267971
    Abstract: A system and method for metering the application of liquid agricultural chemicals to the soil from a moving vehicle at a substantially constant preselected application rate, e.g. gallons per acre, substantially independent of vehicle speed. The system uses a centrifugal pump driven at a rate substantially linearly proportional to vehicle speed and having its outlet pressure substantially proportional to the square of its speed. The pump receives liquid from a supply tank and delivers it to liquid discharge orifice means the rate of flow through which is substantially proportional to the square root of the pressure thereon. The system also includes a line having adjustable orifice means therein controllable by the vehicle driver while the vehicle is moving for returning a portion of pump delivery liquid to the tank and controlling upstream pressure. Orifice pressure Pn required to achieve a preselected application rate at a selected vehicle speed can be determined readily.

  • Patent number: 4141676
    Abstract: A method and apparatus are shown for use in mixing agricultural chemicals for placement through an applicator onto the soil. A fumigant is added to anhydrous ammonia in measured amounts as the ammonia is being injected in the field from the applicator under pressure. The liquid fumigant, which is quite corrosive to some of the aluminum valves and fittings ordinarily used with anhydrous ammonia, is pumped under pressure to be mixed with the ammonia downstream from the aluminum valves and fittings that might be damaged thereby and upstream from the applicator so that a solution or homogeneous mixture of the anhydrous ammonia and fumigant can be delivered to the ground without damage to any equipment because of the corrosive characteristic of the fumigant.

  • Patent number: 4100610
    Abstract: A storage tank for liquid suspensions is shown, requiring sparging or agitation to prevent settling or salting out of somewhat insoluble suspended solids wherein the agitation is provided by movable high energy jets produced by nozzles that direct streams of compressed gas toward and under the precipitated agglomerations of solid particles. The apparatus includes means for distributing the energy of the compressed gas evenly over the surface area upon which the precipitate is deposited whereby to apply the needed agitation to all areas covered by deposits. The invention includes structural aspects for mounting the sparging apparatus on the top of the tank and suspending the moving agitators to extend downwardly into the tank to a position over the floor of the tank upon which the salting out takes place.
