  • Patent number: 9995306
    Abstract: A method of controlling fluid flow in a fluid network system by fluid machines includes obtaining a respective current flow rate associated with each fluid machine, obtaining a current fluid machine speed of each fluid machine, obtaining desired flow rates in the system, and determining a new fluid machine speed for each fluid machine based on the current fluid machine speed and a change in the fluid machine speed required to obtain the desired flow rates. The change in fluid machine speed is determined by minimizing a total fluid machine power which is a function dependent of the change in the fluid machine speed, the minimization being performed with constraints for flow rate, fluid machine pressure and fluid machine speed. The method include controlling the speed of the fluid machines according to the new fluid machine speeds such that the minimum total fluid machine power in the system is attained.

  • Patent number: 9991836
    Abstract: Systems and methods for operating linear motors, and for determining whether a linear motor has reached the end of its power and return strokes. In one embodiment, an electric drive controller of an ESP system monitors position signals received from the system's linear motor and determines transition time differentials, transition counts from the beginning of a stroke, elapsed stroke times and related parameters. If predetermined conditions relating to these parameters are met, the controller determines that the linear motor's mover has reached the end of its stroke. The controller therefore reverses the phase order of the drive's output power and thereby reverses the direction of the mover.

  • Patent number: 9918814
    Abstract: An apparatus (100, 100?) is configured such that passage of a fluid (30) through an open port of a distal tip (112, 112?) enables detection of a substance (116) that may be present on a surface (31, 33), e.g., a surface of a tooth, based on measurement of a signal correlating to a substance at least partially obstructing the passage of fluid (30) through the open port. The apparatus (100, 100?) includes a proximal pump portion (124) and at least one distal probe portion (110) configured to be immersed in another fluid (11), e.g., water in toothpaste foam. A corresponding system (3000) includes one or two such apparatuses (3100, 3200). A method of detecting the presence of a substance on a surface includes probing an interaction zone (17) for at least partial obstruction of flow of the second fluid medium (30) through a distal probe tip.

    Abstract: A battery management method for one or more batteries in a healthcare delivery system is provided. The method includes determining when the healthcare delivery system is drawing power from the one or more batteries and controlling a display unit coupled to the controller to display an initial number corresponding to a time remaining on battery (TROB) when the healthcare delivery system is drawing power from the one or more batteries. The method also includes determining if the TROB is within a reserve range extending up to a reserve range maximum that is less than a maximum TROB, changing the TROB according to an operational state of the healthcare delivery system if the TROB is greater than the reserve range maximum, and decreasing the TROB to count down the TROB without regard for the operational state of the healthcare delivery system if the TROB is less than the reserve range maximum.

  • Patent number: 9789247
    Abstract: A method for discharging fluid from a syringe and for mitigating occlusion conditions includes actuating the plunger of a syringe into a barrel. The method monitors fluid pressure within the barrel of the syringe and determines that an occlusion exists when the fluid pressure exceeds a predetermined threshold. The method actuates the plunger out of the barrel by a predetermined amount in response to the detected occlusion and actuates the plunger of the syringe into the barrel until a measured fluid pressure within the barrel of the syringe exceeds another predetermined threshold.
