  • Patent number: 11142177
    Abstract: A method for operating an electronic brake system for motor vehicles includes determining, by a brake control unit, respective brake pressures acting on wheel brakes by controlling a pressure distribution ratio of brake pressures acting on wheel brakes of a front axle to brake pressures acting on wheel brakes of a rear axle of the motor vehicle. The method further includes receiving, by the brake control unit, driver brake requests determined by a driver of the motor vehicle and/or external brake requests and determining, by the brake control unit, appropriate brake pressures. The brake control unit takes into consideration an initial pressure distribution ratio value, which is ascertained in a driver braking mode or in a pressure control mode and is stored and kept available for later consideration.

  • Publication number: 20210310940
    Abstract: Various techniques are provided for increasing contrast between gas features and other features in a scene. In one example, a method includes receiving a captured image frame comprising a plurality of pixels having a first range of associated pixel values. The method also includes receiving a selection of a subset of the pixels, wherein the subset comprises a gas feature and a scene feature. The method also includes determining a span associated with the pixels of the subset having a second range of associated pixel values smaller than the first range. The method also includes scaling the captured image frame to provide an adjusted image frame limited to the second range of pixel values associated with the span to increase contrast between the gas feature and the scene feature. The method also includes displaying the adjusted image frame. Additional methods and systems are also provided.

  • Publication number: 20210220068
    Abstract: The present invention relates to a medical robot system capable of effectively removing a calcified thrombus in a blood vessel. The present invention proposes a new guide-wired helical microrobot for mechanical thrombectomy applied to a calcified thrombus. Also, the present invention proposes an electromagnetic navigation system (ENS) which uses a high frequency operation that is based on a resonant effect in order to enhance the boring force of a microrobot. The microrobot system of the present invention can precisely tunnel through a blood vessel blockage site by means of the electromagnetic navigation system without damaging blood vessel walls. The microrobot system of the present invention has a wide range of applications including not only for thrombosis, but also thromboangiitis obliterans caused by vasoocclusion, cerebral infarction, strokes, angina or myocardial infarction, peripheral artery occlusive disease, or atherosclerosis, etc.

  • Patent number: 11069381
    Abstract: This disclosure describes techniques for utilizing sensor data to automatically determine the results of events within a system. Upon receiving sensor data indicative of an event, the techniques may analyze the sensor data to determine a result of the event, such as that a particular user associated with a user identifier selected a particular item associated with an item identifier. The techniques described herein may determine when sensor data is to be stored for a default amount of time, and when sensor data is to be stored for a greater amount of time. By retaining data in an intelligent manner, the system is able to function accurately without unduly taxing storage constraints.

  • Publication number: 20210205735
    Abstract: A sand separation system and method for operating a sand separation system, in which the method includes separating sand from a fluid using a separator. The method includes, signaling for a blowdown unit to blowdown the separator, opening one or more blowdown valves of the blowdown unit coupled to the separator in response to the signaling, so as to blowdown the separator, and receiving the sand from the separator into a sand disposal unit. The sand passes through the one or more blowdown valves that are opened. The method includes measuring a weight of at least some of the sand that was separated in the separator using a load cell of the separator, a load cell of the sand disposal unit, or both, and determining a blowdown interval for subsequent blowdown operations of the separator based in part on the weight of the sand.
