Abstract: Methods, systems, and non-transitory computer-readable media for generating augmented data to train a deep neural network to detect traffic lights in image data. The method includes receiving a plurality of real roadway scene images and selecting a subset of the plurality of real roadway scene images. The method also includes selecting an image from the subset and determining a distribution indicting how likely each location in the selected image can contain a traffic light. The method further includes selecting a location in the selected image by sampling the distribution and superimposing a traffic light image onto the selected image at the selected location to generate an augmented roadway scene image. The method also includes processing each image in the subset to generate a plurality of augmented roadway scene images. The method further includes training a deep neural network model using the pluralities of real and augmented roadway scene images.

The audio data from the first wireless intercom device is transmitted to the intercom system through a second wireless access point in response to a determination that the second wireless access point is the home access point for the first wireless intercom device.

Abstract: A method and apparatus for determining misalignment of a radar sensor unit mounted to a vehicle includes providing targets on an alignment apparatus. A vehicle is located at predetermined location on a test station an exact given distance from the alignment apparatus. The actual locations and distances of the targets from each other and from radar sensor unit of the vehicle at the test station are known and pre-stored. At least one target is a greater distance from the vehicle than the other targets. The targets receive and return a radar wave from the radar sensor unit. The radar sensor unit determines locations and distances of the targets and compares with the given or actual locations and distances of the targets to determine misalignment of the radar sensor unit. A calibration program automatically calibrates azimuth and elevation to adjust for misalignment.

Abstract: In an internal combustion engine, the fuel is conveyed by an electrically driven fuel pump. The intake side of this pump is connected to a fuel tank and its outlet side is connected to a pressure region. A prerun of the electrically driven fuel pump may be performed before the startup of the internal combustion engine. In order to increase the service life of the fuel pump, an actual pressure (pactual) in the pressure region may be detected by a pressure sensor and the execution of the prerun be a function of at least the signal of the pressure sensor.

A sealing slide is disposed coaxially to the gas exchange valve, is acted upon by the force of a coupling spring, and is displaceable axially back and forth by the valve control unit.

Abstract: The invention concerns an inductive transmitter comprising two coils (1, 2), each with one core (3, 4). The two cores (3, 4) are capable of being moved relative to each other. Two systems are integrated in the transmitter that make it possible to simultaneously transmit data and/or energy, as well as the position of the two cores (3, 4) relative to each other. Finally, the transmission of data and/or energy takes place by means of induction, and the determination of the position of the two cores (3, 4) relative to each other takes place via a measurement of the magnetic field that exists between the two coils (1, 2).

Abstract: A circuit for operating an electric motor (10) has a triac (24) that is parallel to the electric motor (10). The triac (24) is acted upon by a first control signal (28) that is dependent on the voltage present at a first connection (11) of the electric motor (10). The triac (24) is further acted on by a second control signal (22) that is emitted as a braking signal by a motor-control circuit (19). The circuit of the invention, which includes a semiconductor component (24), permits both a braking of the electric motor (10) and the damping of an inductive voltage peak during the switch-off process of the electric motor (10). The damping of the inductive voltage peak is also assured after the separation of the voltage from an energy source (16).
