Abstract: A method for selecting a driving maneuver to be carried out by an at least semi-autonomously driving vehicle is disclosed. The method includes (i) using measurement data of at least one sensor carried by the vehicle, creating a representation of the situation the vehicle is in, (ii) mapping the representation of the situation to a probability distribution by way of a trained machine learning model, which probability distribution specifies a probability for every driving maneuver from a predefined catalog of available driving maneuvers, with which said driving maneuver is carried out, (iii) selecting a driving maneuver from the probability distribution as the driving maneuver to be carried out, (iv) in addition to using at least one aspect of the situation the vehicle is in, a subset of driving maneuvers which are disallowed in this situation is determined, and (v) this disallowed driving maneuver is prevented from being carried out.

Abstract: A method for training a behavior planner for an at least partially self-driving target vehicle on the basis of observation data regarding kinematics and/or dynamics that have been recorded during at least one test drive in a test vehicle includes identifying a driving maneuver that moves the test vehicle from an initial state to an end state using the observation data, ascertaining the maneuver end time, retrieving a maneuver duration required by the target vehicle to perform the identified driving maneuver from a dynamics model of the target vehicle, labeling observation data from a time interval, defined by the maneuver duration, with the identified driving maneuver, and training the behavior planner, using the labeled observation data, to map observation data that indicate a state of the target vehicle to at least one driving maneuver to be performed.

Abstract: A method for producing oil and/or gas from an underground formation comprising locating a suitable reservoir in a subsurface formation; creating a model of the reservoir; populating the model with laboratory data; modeling the reservoir to determine fluid displacements based on fluids injected and fluids produced; determining an optimum fluid mixture for the fluids to be injected based on a series of sensitivity analyses performed with the model; drilling a first well in the formation; injecting the optimum fluid mixture into the first well; drilling a second well in the formation; and producing oil and/or gas from the second well.

Abstract: A motor vehicle auxiliary heater annular combustion air blower is disclosed having a housing defining a suction side of the blower and a delivery side of the blower. The housing also defines a mounting bore which extends substantially perpendicular to the bypass channel. A rotary slide valve is provided in the form of a cylindrical pin member which is rotatable within said mounting bore and includes a surface before variable throttling of said bypass channel independence upon the rotational position of said rotary slide valve.

Abstract: An arrangement for space heaters for motor vehicles, which are fired with liquid fuel including, (depending on the type of burner used), a glow plug for either igniting a fuel/air mixture and/or vaporizing fuel. Only one type of glow plug, i.e., a glow plug designed for a 12-V electrical system, is normally employed. If the motor vehicle has a 24-V battery, a compensating resistor, which has the same electrical resistance as the glow plug, is connected in series with the glow plug. The amount of electrical energy converted into heat in the compensating resistor is practically equal to that transformed in the glow plug. The compensating resistor is integrated within the burner housing, in which case it is located in the flow path of the combustion air and is properly cooled by the air flowing past it, to provide a safe trouble free and space-saving arrangement.

Abstract: A cutting segment for stone and the like, the segment having a porous center section. A conventional mixture of cement and diamonds is made, and a quantity of filler is added to the mixture. The filler will withstand the sintering process, but subsequently falls out so pores are provided. A segment is made with only the center porous, while the side sections are as dense as is conventional. The result is that the porous section can receive coolant and/or the resulting slurry for efficient cutting, and the center section wears faster to yield a concave cutting edge.

Abstract: A method for the production of electret filaments or fibers from high molecular weight substances is described which consists of melting the substances and extruding them through die orifices, electrically charging, polarizing and cooling the formed filaments or fibers and the electrically charging and polarization is carried out immediately prior to the issuance or during the issuance from the die orifices while the substances are in a molten state.
