  • Patent number: 10788947
    Abstract: Navigation between input elements of a graphical user interface (GUI) using a pointing device to control an interaction with the GUI. The method includes: activating a mode of operation between discrete input elements in the GUI; snapping the cursor to a first input element, wherein the movement of the cursor is then restricted to the first input element and input to the input element is receivable via user interaction with the pointing device; detecting a movement of the pointing device representing an intended movement from the first input element to another input element, including obtaining an angle of the movement; selecting a most likely intended input element as the target of the movement by evaluating positions of other input elements in a current user display of the GUI and comparing the angle of the movement with the positions of the other input elements.

  • Publication number: 20200240105
    Abstract: This description provides an autonomous or semi-autonomous excavation vehicle that is capable of navigating through a dig site and carrying out an excavation routine using a system of sensors physically mounted to the excavation vehicle. The sensors collects any one or more of spatial, imaging, measurement, and location data representing the status of the excavation vehicle and its surrounding environment. Based on the collected data, the excavation vehicle executes instructions to carry out an excavation routine. The excavation vehicle is also able to carry out numerous other tasks, such as checking the volume of excavated earth in an excavation tool, and helping prepare a digital terrain model of the site as part of a process for creating the excavation routine.

  • Publication number: 20190368446
    Abstract: In accordance with the present invention, there are provided simplified systems and methods for catalytically deactivating, removing, or reducing the levels of reactive component(s) from the vapor phase of fuel storage tanks. The simple apparatus described herein can be utilized to replace complex OBIGGS systems on the market. Simply stated, in one embodiment of the invention, the vapor phase from the fuel tank is passed over a catalytic bed operated at appropriate temperatures to allow the reaction between free oxygen and the fuel vapor by oxidation of the fuel vapor, thus deactivating reactive component(s) in the gas phase.

  • Patent number: 10155180
    Abstract: In accordance with the present invention, there are provided systems and methods for contacting two or more fluids, useful, for example for purifying or infusing a fluid (by allowing efficient and/or uniform addition of components to or removal of components from the fluid). The components may be undesirable components to be removed from a fluid, or a desired component or components to be added to the fluid, for example, each of which is referred to herein as “component”. In this regard, the disclosed embodiments provide for the purification or infusion of a fluid by passing a liquid and a fluid through a contacting zone which facilitates intimate mixing of the liquid and the fluid. A differential of partial pressure, activity, fugacity or concentration of the components between the liquid and the fluid facilitates the transfer of the components between the liquid and the fluid in the intimately mixed liquid and fluid.

  • Patent number: 8540617
    Abstract: An extracorporeal pumping method includes receiving an inlet fluid into a compressible-expandable bladder sealably mounted within a housing and moving an actuating member mounted within a fluid chamber of a hydraulic actuating sub-assembly. A pressure transmissive fluid is displaced from the fluid chamber into the housing. The method includes compressing a volume of the bladder in the housing using the transmissive fluid displaced into the housing, the compressed bladder ejecting the inlet fluid from the bladder to provide an outlet fluid under pulsatile pressure. The actuating member is moved within the fluid chamber and the displaced transmissive fluid is returned from the housing into the fluid chamber. The method includes expanding the compressed bladder in the housing and receiving additional inlet fluid into the bladder. The movement of the actuating member is controlled such that the outlet fluid exhibits a predetermined pulse rate, stroke volume, and upstroke rise time.
