Abstract: In a method and apparatus to correct a signal phase in the acquisition of magnetic resonance signals of an object to be examined in a slice multiplexing method, magnetic resonance signals from at least two different slices of the object are detected simultaneously. In at least one slice-selection time period, a slice-selection gradient is generated by a slice-selection-gradient pulse. During the activation of the slice-selection gradient in each case a radio-frequency pulse with a slice-specific frequency is emitted for each of the slices. The radio-frequency pulses for the different slices at least partially temporally overlap and are temporally offset for the phase correction, so the duration of the slice-selection time period is shortened by modification of the slice-selection gradients.

Abstract: The Time-of-Flight (TOF) technique is combined with analog amplitude modulation within each pixel in an image sensor. The pixel may be a two-tap pixel or a one-tap pixel. Two photoelectron receiver circuits in the pixel receive respective analog modulating signals. The distribution of the received photoelectron charge between these two circuits is controlled by the difference (or ratio) of the two analog modulating voltages. The differential signals generated in this manner within the pixel are modulated in time domain for TOF measurement. Thus, the TOF information is added to the received light signal by the analog domain-based single-ended to differential converter inside the pixel itself. The TOF-based measurement of range and its resolution are controllable by changing the duration of modulation. An autonomous navigation system with these features may provide improved vision for drivers under difficult driving conditions like low light, fog, bad weather, or strong ambient light.

Abstract: LIDAR measurements can be sparse in comparison to camera measurements. Hence, dynamically steering a LIDAR to regions of a field of view with more information (e.g. the detailed boundaries of objects) is beneficial. In one embodiment, a LIDAR system performs a non-uniform laser scan of a field of view based on sensor data. Data from an on-going or previous scan can be used to define dense scan regions within the field of view. The shape of dense scan regions can be iteratively improved (e.g. narrowed) based on localization of time-of-flight boundaries. Dense scan regions can be expressed in term of a set of laser steering parameters operable to dynamically steer a LIDAR. Within embodiments complex-shaped dense scan patterns can be selected or adapted based on an object classification (e.g. person or vehicle) or LIDAR location (e.g. an urban environment).
