Abstract: A medical system includes a head having an end arranged to face a reference plane and a multistage slide mechanism coupled with the head. The multistage slide mechanism includes a coarse-float mechanism configured to enable movement of the head relative to the reference plane, and to prevent movement of the head toward the reference plane while allowing movement of the head away from the reference plane. A one-way brake associated with the coarse-float mechanism is configured to transition between a locked state and an unlocked state in response to a presence of or an absence of a first triggering event. In the locked state, the one-way brake prevents movement of the head toward the reference plane and simultaneously allows movement of the head away from the reference plane. In the unlocked state, the one-way brake allows movement of the head toward the reference plane and movement of the head away from the reference plane.

Abstract: A Brayton cycle engine including a longitudinal wall extended along a lengthwise direction. The longitudinal wall defines a gas flowpath of the engine. An inner wall assembly is extended from the longitudinal wall into the gas flowpath. The inner wall assembly defines a detonation combustion region in the gas flowpath upstream of the inner wall assembly.

Abstract: A Brayton cycle engine and method for operation. The engine includes an inner wall assembly and an upstream wall assembly each extended from a longitudinal wall into a gas flowpath. An actuator adjusts a depth of the detonation combustion region into the gas flowpath between the inner wall assembly and the upstream wall assembly. The engine flows an oxidizer through the gas flowpath and the inner wall captures a portion of the oxidizer. The engine further adjusts the captured flow of oxidizer via the upstream wall and flows a first flow of fuel to the captured flow of oxidizer to produce rotating detonation gases. The engine flows the detonation gases downstream and to mix with the flow of oxidizer, and flows and burns a second flow of fuel to the detonation gases/oxidizer mixture to produce thrust.

Abstract: A handheld controller configured to be held by a user's hand. The handheld controller comprising a main body, and a handle extending from the main body, wherein the handle has a palm side and a finger side. A control button is positioned on the main body or handle, and a detection sensor is on the handle. The detection sensor is positioned to detect the presence of the finger or palm of a user's hand engaging the handle. The detection sensor can be a capacitive touch sensor, a proximity sensor or other detection sensor operative to detect the touch or spatial presence of the user's hand or fingers.

Abstract: A Brayton cycle engine including an inner wall assembly defining a detonation combustion region upstream thereof extended from a longitudinal wall into a gas flowpath. An actuator adjusts a depth of the detonation combustion region into the gas flowpath. A method for operating the engine includes flowing an oxidizer through the gas flowpath; capturing a portion of the flow of oxidizer via the inner wall; flowing a first flow of fuel to the captured flow of oxidizer; producing a rotating detonation gases via a mixture of the first flow of fuel and the captured flow of oxidizer; flowing at least a portion of the detonation gases downstream to mix with the flow of oxidizer; flowing a second flow of fuel to the mixture of detonation gases and oxidizer; and burning the mixture of the second flow of fuel and the detonation gases/oxidizer mixture.

Abstract: A method, system, and computer readable storage to implement a data marketplace which stored data assets, such as tables, models, variables, etc. All of the data assets (assets) can be searched and retrieved from the data marketplace notwithstanding that the assets can be stored at different locations, in different forms, and in different platforms through an entire big data system. The data marketplace also predicts and suggests assets which will be likely to be relevant to a user's current project.

Abstract: The present disclosure is directed to a rotating detonation combustion system for a propulsion system including a plurality of combustors in adjacent arrangement along the circumferential direction. Each combustor defines a combustor centerline extended through each combustor, and each combustor comprises an outer wall defining a combustion chamber and a combustion inlet. Each combustion chamber is defined by an annular gap and a combustion chamber length together defining a volume of each combustion chamber. Each combustor defines a plurality of nozzle assemblies each disposed at the combustion inlet in adjacent arrangement around each combustor centerline. Each nozzle assembly defines a nozzle wall extended along a lengthwise direction, a nozzle inlet, a nozzle outlet, and a throat therebetween, and each nozzle assembly defines a converging-diverging nozzle. A first array of combustors defines a first volume and a second array of combustors defines a second volume different from the first volume.

Abstract: A user device, such as a smartphone or a tablet computer, can provide a user with information pertaining to operations of an autonomous robotic lawnmower to assist the user with monitoring the operations of the robotic lawnmower and with setting up the autonomous robotic lawnmower. For example, the user device can present example lawn shapes and recommended locations of beacons suitable for these lawn shapes, can indicate the quantity of beacons detected by the autonomous robotic lawnmower, can be used to establish a region on a lawn where the autonomous robotic lawnmower performs a particular behavior, can be used to select a grass height that the autonomous robotic lawnmower cuts the lawn, and can be taught a particular path to take when returning to a docking station to charge the autonomous robotic lawnmower.
