  • Patent number: 11293747
    Abstract: An embodiment of the invention relates to a method for carrying out a time-resolved interferometric measurement comprising the steps of generating at least two coherent waves, overlapping said at least two coherent waves and producing an interference pattern, measuring the interference pattern for a given exposure time, thereby forming measured interference values, and analyzing the measured interference values and extracting amplitude and/or phase information from the measured interference values. In at least one time segment, hereinafter referred to as disturbed time segment, of the expo-sure time, the interference pattern is intentionally disturbed or destroyed such that the corresponding measured interference values describe a disturbed or destroyed interference pattern.

  • Patent number: 10712432
    Abstract: Time-of-flight (TOF) based systems using light pulse compression are described and, in some cases, can help increase demodulation contrast. Further, light pulse shaping techniques are described that, in some cases, can help reduce phase non-linearity and distance-calculation errors. The techniques can be used, for example, in measurement systems, as well as imaging systems in which a time-of-flight and/or distance information is obtained. The time-of-flight and/or distance information can be used to reconstruct and display a three-dimensional image of a scene. The light compression techniques also can be used to provide reference signals.

  • Patent number: 10705192
    Abstract: Optoelectronic modules (100) are operable to distinguish between signals indicative of reflections from an object of interest and signals indicative of a spurious reflection. Various modules are operable to recognize spurious reflections by means of dedicated spurious-reflection detection pixels (126) and, in some cases, also to compensate for errors caused by spurious reflections.

  • Publication number: 20200062143
    Abstract: An electrified road transport system includes a contact line system having a plurality of masts with support cables and contact wires suspended thereon. The contact line system has structural modifications for reducing the horizontal and/or vertical positional tolerances of the contact wires. In the context of the structural modifications, section separators are fastened directly to masts or to cantilevers of the masts, skewed overhead lines are disposed in straight section segments and/or in curves, and the support cables and/or contact wires have smaller cross-sections and/or higher longitudinal tensile forces. A method for stabilizing a contact line system of an electrified road transport system is also provided.

  • Patent number: 10359505
    Abstract: The present disclosure describes optical imaging and optical detection modules that include sensors such as time-of-flight (TOF) sensors. Various implementations are described that, in some instances, can help reduce the amount of optical cross-talk between active detection pixels and reference pixels and/or can facilitate the ability of the sensor to determine an accurate phase difference to be used, for example, in distance calculations.

  • Patent number: 10108201
    Abstract: A vehicle control facility for the automated control of an electrical road vehicle for a route system with an energy-supply system that includes a lane-bound energy supply line, in particular an overhead line system. A position-determining unit determines a geographical position of the electrical road vehicle. A specific-lane-determining unit determines position data for a specific lane assigned to the lane-bound energy supply line. A communication interface transmits current relative positions of infrastructure features with respect to the electrical road vehicle to an external central specific-lane-determining facility and receives position data. A vehicle-control unit controls the electrical road vehicle with respect to the determined specific lane in dependence on the determined relative position of the specific lane.

  • Patent number: 10046669
    Abstract: A vehicle has an electric or hybrid-electric traction drive supported by an ungrounded vehicle frame. The vehicle also has a current collector, which can be electrically connected to the traction drive and which can be brought in galvanic contact with a contact line of a grounded contact-line system to supply traction energy. The vehicle contains an electrical protection system for avoiding dangerous contact voltages on the vehicle frame or on a vehicle part connected to the vehicle frame in a conductive manner. The protection system has a first protection stage, a second protection stage, and a switching element, by which the protection system can be switched between the first and the second protection stages. The first protection stage provides greater safety from dangerous contact voltages than the second protection stage. Thus, a protection system can be provided which provides sufficient safety in all operating states of the vehicle.

  • Patent number: 9698196
    Abstract: A demodulation pixel improves the charge transport speed and sensitivity by exploiting two effects of charge transport in silicon in order to achieve the before-mentioned optimization. The first one is a transport method based on the CCD gate principle. However, this is not limited to CCD technology, but can be realized also in CMOS technology. The charge transport in a surface or even a buried channel close to the surface is highly efficient in terms of speed, sensitivity and low trapping noise. In addition, by activating a majority carrier current flowing through the substrate, another drift field is generated below the depleted CCD channel. This drift field is located deeply in the substrate, acting as an efficient separator for deeply photo-generated electron-hole pairs. Thus, another large amount of minority carriers is transported to the diffusion nodes at high speed and detected.

  • Publication number: 20170087991
    Abstract: A non-rail bound, electrically or hybrid-electrically driven vehicle has a current collector for feeding electric traction energy from an overhead line system. The current collector has a sliding strip that is brought into sliding contact with a contact wire of the overhead line system above a travel lane. The sliding strip arrangement is pivotable transversely to a direction of travel. The vehicle has a limiter to at least unilaterally limit the transverse pivoting range of the sliding strip arrangement substantially to the width of the vehicle. A driver assistance system assists a driver in adhering to a virtual track within the marked lane. The track width and the pivoting range are dimensioned such that, when the track is adhered to, it is possible to maintain sliding contact between the sliding strip arrangement and the contact wire.
