  • Publication number: 20260072173
    Abstract: Systems and methods are provided for count-free, equi-depth histograms that may be used in 3D imaging. In one embodiment, a method comprises receiving, at a binner, a stream of photon return events from a pixel of an imaging detector, the stream of photon return events generated by photons transmitted from a pulsed light source and reflected off an object in a scene, classifying, with the binner, each photon return event as either an early event or a late event based on a reference signal controlled by a control value, the control value configured to change based on a relative proportion of early events to late events, and outputting, from the binner, the control value upon request, the control value usable to determine a distance of the object in the scene.

  • Patent number: 12062994
    Abstract: The present invention relates to a circuit arrangement having an active rectifier circuit, in particular on a secondary side of an inductive energy transmission path. The circuit arrangement has a half or full bridge of power transistors for rectifying an AC voltage induced in an input inductor of the circuit arrangement. The power transistors are connected to the input inductor in such a way that an auxiliary voltage is split off from the induced AC voltage for switching the power transistors. As a result, even large currents, which result in a low output voltage, can be transmitted without endangering the operation of the rectifier circuit.

  • Patent number: 11870307
    Abstract: The present invention relates to a method for increasing the efficiency of an energy transfer device (100) with which electrical energy is converted contactlessly into electrical energy with the aid of a magnetic field in order to electrically excite a rotor of an electrical machine, comprising the step of: arranging an additional electrically conductive material layer (13) on at least one active part (12, 19, 35, 45) of the energy transfer device (100), wherein an active part of the energy transfer device (100) is a part of the energy transfer device (100) which is at least partially exposed to the magnetic field used for energy transfer, and wherein the electrical conductivity of the additional material layer (13) is greater than the electrical conductivity of the at least one active part (12, 19, 35, 45). Moreover, the invention relates to an energy transfer device (100) and to a use of an electrically conductive material.

  • Publication number: 20230417807
    Abstract: A method for detecting a faulty voltage sensor of a group of n?3 voltage sensors of controllers in an onboard electrical system of a vehicle, wherein (a) voltage measurement values from n?1 voltage sensors are averaged, (b) the deviation of a voltage measurement value of the remaining voltage sensor from the averaged voltage measurement value is determined, and (c) if the deviation satisfies a specified criterion, an error message relating to a fault of the remaining voltage sensor is output and at least steps (a) to (b) are carried out for the voltage sensors in a commutated manner.

  • Patent number: 10789254
    Abstract: Architecture introduces a new pattern operator referred to as called an augmented transition network (ATN), which is a streaming adaptation of non-reentrant, fixed-state ATNs for dynamic patterns. Additional user-defined information is associated with automaton states and is accessible to transitions during execution. ATNs are created that directly model complex pattern continuous queries with arbitrary cycles in a transition graph. The architecture can express the desire to ignore some events during pattern detection, and can also detect the absence of data as part of a pattern. The architecture facilitates efficient support for negation, ignorable events, and state cleanup based on predicate punctuations.
