Abstract: A device for a hydraulic braking system of a vehicle. The device includes a processing unit, which is programmed to determine at least one brake characteristic value of the hydraulic braking system, the processing unit being programmed to determine the at least one brake characteristic value as a vehicle axle-specific brake characteristic value, which in each case corresponds to a ratio between a brake pressure in all wheel brake cylinders assigned to a shared vehicle axle of the vehicle and a vehicle axle braking torque exerted on the shared vehicle axle with the aid of the wheel brake cylinders. A method for determining at least one brake characteristic value of a hydraulic braking system of a vehicle, and a method for decelerating a vehicle with a hydraulic braking system and an electric motor usable as a generator, are also described.

Abstract: Systems and methods for identifying a status of components of hydraulic fracturing units including a prime mover and a hydraulic fracturing pump to pump fracturing fluid into a wellhead via a manifold may include a diagnostic control assembly. The diagnostic control assembly may include sensors associated with the hydraulic fracturing units or the manifold, and a supervisory control unit to determine whether the sensors are generating signals outside a calibration range, determine whether a fluid parameter associated with an auxiliary system of the hydraulic fracturing units is indicative of a fluid-related problem, determine whether lubrication associated with the prime mover, the hydraulic fracturing pump, or a transmission of the hydraulic fracturing units has a lubrication fluid temperature greater than a maximum lubrication temperature, or determine an extent to which a heat exchanger assembly associated with the hydraulic fracturing units is cooling fluid passing through the heat exchanger assembly.

Abstract: A method whereby the date of birth (age) of a customer engaging in e-commerce over the Internet is verified. The present invention is launched from a merchant's website when an age sensitive transaction—alcohol or tobacco purchase, access to an adult web site, etc.,—is being undertaken. The system first checks to see if the customer is a known entity with a known date of birth. If the customer is not appropriately known to the system, then the system checks public records from information supplied to the system by the customer. If the date of birth is still unknown after such a check, the customer uploads an image of photo identification which is checked for date of birth either via software and also a selfie holding the identification. Optional SMS code verification can be undertaken. E-signatures can be optionally collected. Once the date of birth is known, the transaction is approved or denied based on the totality of the facts of the transaction.
