Abstract: A system can perform a method that includes receiving sensor data from a subset of human-driven vehicles that have moved through an intersection in a region, where the sensor data indicates a respective set of trajectories of respective human-driven vehicles of the subset through the intersection. The method can further include processing the sensor data to classify driving behavior of each human-driven vehicle of the subset of human-driven vehicles through the intersection. The method can further include classifying the intersection to label an autonomy map to include pass-through information for at least one of autonomous vehicles or semi-autonomous vehicles driving through the intersection.

Abstract: A computing system can receive sensor data from a set of human-driven vehicles operating through a road segment. The system can process the sensor data to determine a set of right-of-way rules for autonomous vehicle driving through the road segment. In certain examples, the system can obtain an autonomous driving map utilized by autonomous vehicles for operating through the road segment, and modify the autonomous driving map to include the set of right-of-way rules for the road segment.

Abstract: A battery pack has a closed housing with an inner receiving space for several battery cells. The housing has a general basic shape with first and second side walls. The side walls of the housing are made of a heat-conducting material. The inner surfaces of the side walls limit the receiving space. In order to create a thermally balanced battery pack, a cell assembly including several battery cells is accommodated in the receiving space. A battery cell has flat sides and edge sides. The battery cells lie with their flat sides stacked next to each other such that there are outer battery cells and inner battery cells. The outer battery cells rest with their flat sides in a flat and heat-transferring manner against the inner surfaces of the first side walls of the housing, and the inner battery cells are heat-transferring to the outer battery cells of the cell assembly.

Abstract: An electronic device may include wireless circuitry having an amplifier configured to receive a radio-frequency signal generated from a baseband signal, a first adjustable load component coupled to an output of the amplifier, a second adjustable load component coupled to the output of the amplifier, and a control signal generator configured to output one or more control signals for tuning the first and second adjustable load components based on an envelope of the baseband signal or the radio-frequency signal. The first adjustable load component can provide a first tuning range covering a first subrange of an instantaneous signal envelope of the baseband signal or the radio-frequency signal, whereas the second adjustable load can provide a second tuning range covering a second subrange of the instantaneous signal envelope of the baseband signal or the radio-frequency signal. The first and second tuning ranges are combined to provide an extended tuning range.

Abstract: This disclosure is directed to compensating for gain drift due to switching the output power of a transmitter of an electronic device. In some cellular network applications, the transmit power level of a transmitter may be frequently adjusted from a low power level to a high power level. If the power level is not switched to the desired power level within a given interval, the transmission signal may be distorted. To enable the transmitter to reach a desired output power within the interval, the voltage supply of a power amplifier may be raised during a low power symbol, which may produce an undesirable gain increase. To mitigate or eliminate the low power symbol gain increase, a gain compensation signal may be introduced into the transmitter. The compensation signal may be adjusted and refined by implementing a power control loop, the power control loop may include a power controller.

Abstract: Wireless circuitry can include a processor that generates a baseband signal, an upconversion circuit that upconverts the baseband signals to a radio-frequency signal, and an amplifier that amplifies the radio-frequency signal. A tunable delay circuit can be used to selectively delay generation of the radio-frequency signal or to delay generation of another signal intended for the radio-frequency amplifier. The tunable delay circuit can be controlled using a closed-loop delay adaptation scheme. A feedback receiver that is coupled to an output of the amplifier can be used to generate a demodulated signal. A delay error measurement circuit can be used to receive the demodulated signal, to detect a peak by monitoring when an envelope of the demodulated signal crosses a threshold level, to compute an amount of asymmetry in the detected peak, and to output a signal that is used to control the tunable delay circuit.

Abstract: A battery pack for exchangeable insertion into a receiving compartment delimited by an inner wall has a housing accommodating battery cells. The housing has a basic shape with an upright side and first and second end walls opposite each other. The upright side extends in upright direction of the housing between the first and second end walls. The upright side has an outer surface and longitudinal ribs arranged thereon and extending in upright direction. The longitudinal ribs have a height measured in upright direction and are positioned at a distance from each other. The distance is measured transversely to the upright direction. The longitudinal ribs delimit together with the outer surface of the upright side a cooling groove extending in upright direction. The longitudinal ribs are designed along the height such that the cooling groove can delimit, together with the inner wall, a cooling channel extending in upright direction.
