  • Patent number: 11199161
    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: 11111647
    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.

  • Patent number: 11082514
    Abstract: A method, computer system, and computer program product for reducing the display of duplicate push notifications in a device having a plurality of applications is provided. A first one of the plurality of applications is identified as a preferred one of the plurality of applications from which push notifications are to be displayed on the device. The focus of each of the duplicate push notifications is determined. A determination is made as to whether the focus of a first push notification received from the first one of the plurality of applications is the same as the focus of a second push notification received from a second one of the plurality of applications. Responsive to the focus of the first push notification being the same as the focus of the second push notifications, only the first push notification is displayed on the device.
