Abstract: For manufacturing-related reasons, the qubits of known quantum computers are not to be regarded as equivalent, but instead a standard quantum computer has not only high-performance qubits with long decoherence times and good fidelities of operation but also low-performance qubits with short decoherence times and poor fidelities of operation. The invention utilizes these by subdividing a system to be modeled with such a quantum computer into a bath part of low relevance and a cluster part of high relevance, wherein a rough description of the bath part is assigned to the low-performance qubits and an exact description of the cluster part is assigned to the high-performance qubits.

Abstract: Privacy-preserving federated learning apparatuses, systems, computer program products, and methods are provided that generate an updated global model based on a set of client models while maintaining privacy regarding the data values embodying each client model and the updated global model. In this regard, masked client models are utilized, which cryptographically obfuscate data values embodying the client model while still enabling combination, or “aggregation,” of the masked client models to generate a masked updated global model. The masked updated global model similarly includes obfuscated data values embodying the updated global model, but may be unmasked to reveal the true values of the updated global model for use. Some embodiments utilize specific steps for communication between environments, systems, devices, and/or the like, to ensure the masked models can only be unmasked by intended entities.

Abstract: An electrical hand-tool device and start-up safety routine protecting against start-up blockages, in which an electrical motor is connected, for a short time span (T0), with the current supply at a determinable resistance. At least one of a limit value (&agr;G) and a shut-off point in time (tA) is determined, for the safety routine in the event of tool blockage, using a measurement of the angle of rotation (&phgr;) of the rotor taken over the time span (T0) dependent on the start-up behavior of a rotor in the time span (T0).

Abstract: A method controls a vehicle brake system having a service brake and a retarder in a mutually coordinated manner. The retarder is activated during each braking operation and is controlled as a function of the driver's braking desire as well as of driving condition values, road condition values and operating conditions of the vehicle (integrated operation of the retarder).

Abstract: A method controls brake pressure for a motor vehicle pressure medium-actuated power brake system in which the adjustment of a proportionality factor (k) between deceleration and brake pressure starting from an initial value (ko) is limited to a range bounded by a lower limit value and an upper limit value in which range the initial value (ko) is contained. This produces a warning travel of the pedal when excessive deviation of the brake pressure from the expected value occurs. The warning travel informs the driver of the braking effect which is deviating excessively from the expected degree. Methods are known in which a specific travel (sp) of the brake pedal is interpreted as a setting of a specific desired deceleration (zs) of the vehicle and the required brake pressure is set automatically if appropriate by incrementally adjusting a variable proportionality factor (k).

Abstract: A method for producing a deceleration setpoint value of a motor vehicle with an electropneumatic brake actuatable by a brake pedal, especially a compressed-air-actuated brake, with a sustained action brake and with at least one device for actuating the brake independently of the driver's desire (external actuation) is characterized by the fact that, with external actuation of the brake and with a simultaneous change in the brake pedal, a resultant deceleration setpoint (z_res) is formed in such fashion that, beginning with the externally set deceleration setpoint (z_ext) with simultaneous actuation of the brake pedal, a curve of the resultant deceleration setpoint (z_res) with the pedal travel is produced which reaches complete deceleration upon full brake pedal travel.

Abstract: For regulating the driving dynamics of a road vehicle, setpoints for the yaw rate {dot over (&PSgr;)} and the float angle &bgr; of the vehicle are generated continuously by evaluating a simulation computer implemented vehicle model. The simulation computer generates control signals for activating at least one wheel brake of the vehicle based on a comparison of the reference values {dot over (&PSgr;)}SO as a setpoint, and the actual values {dot over (&PSgr;)}I of the yaw rate continuously recorded by a yaw rate sensor. The vehicle model is represented by a linear differential equation system of the form [P]·({overscore ({dot over (X)})})=[Q]·({overscore (X)})+({overscore (C)})·&dgr;(t).

Abstract: The gradient of a roadway in the direction of travel of the vehicle is identified from signals present in the vehicle without any additional sensor systems. A freely rolling state of the at least one driven axle of the vehicle is detected at least once. In this state, the wheels of the driven axle also roll free of slip. In order to balance out the wheel speeds between the driven axles and the non-driven axles, the difference speed between the wheel speed of a driven axle and the wheel speed of a non-driven axle is identified. At the same time, the value of the braking, that is to say the value of the deceleration of the vehicle, is measured. The value of a gradient constant is identified from the identified values of the difference speeds and the braking operations. The gradient of the roadway can be determined with the gradient constant from the values of the difference speed and the values of the braking then identified. The gradient information can then be used to control the vehicle.

Abstract: A method sets the braking effect of the retarder brake as a function of the absolute value of the difference between wheel speed values which are derived from wheel speeds at wheels which can be influenced by the retarder brake and from wheel speeds at wheels which cannot be influenced by the retarder brake. The braking effect is reduced if the absolute value of the difference exceeds a prescribed limit value which is lower than the absolute value of the difference when one of the wheels starts to tend to lock. The effect of the retarder brake can thus already be reduced significantly before the locking point is reached so that the risk of wheels locking which otherwise exists owing to the comparatively slow decrease in braking torque of retarder brakes and thus the associated swerving of the axle of the retarder brake are reliably avoided.

Abstract: A method of wear-dependent braking force distribution prevents adhesion problems without being limited to lowest brake pressures as is the case with conventional methods. Wear control is dispensed with only in the case of operationally very rare braking actions, for example, those above 0.3 g or a learned adhesion threshold. These rare braking actions are limited, in practice, to genuinely critical braking situations. Otherwise, the control interventions are carried out with to produce balanced wear only in the long term; an attempt is made to achieve wear at the same rate rather than simply balanced wear.

Abstract: A process for load dependent braking regulations (ALB) utilizing components, signal paths and transmitters of an existing anti-lock braking system (ABS) to perform an automatically load-dependent braking function which takes effect well below the locking limit. The brake pressure and consequently the brake distribution are controlled by processing only wheel-speed differences as actual values of an electronic brake-pressure controller instead of absolute wheel slips. To compensate for changing load situations and roadway properties, the precontrollable brake-force distribution and the brake-pressure level control triggerable at the pedal are corrected in a self-learning and adaptive manner. The device for carrying out the ALB process consists essentially of a computer and software program using input from the ABS systems. The process according to the invention makes axle-load sensors superfluous.
