Abstract: Several unique configurations for interferometric recording of volumetric phase diffractive elements with relatively high angle diffraction for use in waveguides are disclosed. Separate layer EPE and OPE structures produced by various methods may be integrated in side-by-side or overlaid constructs, and multiple such EPE and OPE structures may be combined or multiplexed to exhibit EPE/OPE functionality in a single, spatially-coincident layer. Multiplexed structures reduce the total number of layers of materials within a stack of eyepiece optics, each of which may be responsible for displaying a given focal depth range of a volumetric image.

Abstract: An apparatus for controlling docking with a spacecraft includes at least one camera for generating at least one image pixel stream of the spacecraft. A field programmable gate array (FPGA) receives the at least one image pixel stream from the at least one camera. The FPGA texture processes the at least one pixel stream to generate at least one texture map for the at least one image pixel stream. A processor receives the at least one texture map from the FPGA and calculates texture map statistics responsive to the generated at least one texture map, generates thresholding results for the at least one pixel image stream responsive to the generated at least one texture map, determines a bus centroid of the spacecraft responsive to the generated thresholding results and outputs the determined bus centroid of the spacecraft. A docking controller controls docking of with the spacecraft responsive to the determined bus centroid of the spacecraft.

Abstract: An emergency brake assistance system includes: a collision risk detection unit (12) to detect a risk of collision with an object in front of the vehicle, based on data from an environment sensor (14) for recording objects in front of the vehicle and data from an accelerator sensor (16) for recording an intention to accelerate by the driver; and a collision avoidance unit (18) to implement measures to prevent a potential collision with the object in front of the vehicle, based on data from the collision risk detection unit. The system temporarily deactivates, for a specified time duration, an override condition of a safety concept of the system when the accelerator sensor records the driver's intention to accelerate and the vehicle speed is below a specified speed threshold. Thus the driver's acceleration command when setting the vehicle in motion temporarily cannot override an automatic actuation of the emergency brake system.

Abstract: In a method for determining at least one, preferably however several driver-independent interventions in a vehicle system, a risk calculator is used, whose input is supplied with predetermined vehicle data, ambience data, current vehicle and driver data, occupant data or data of persons outside the vehicle, or similar data. The risk calculator issues an evaluation of the risk situation of the vehicle and its occupants or the persons outside the vehicle based on said data and, in accordance with the evaluation and optional additional criteria or weightings, outputs driving signals controlling actuators that modify or trigger the driving behavior of the vehicle and/or the occupant protection system and/or protection means for other traffic participants (pedestrians, cyclists, etc.) in such a way that maximum protection is obtained for the persons and the vehicle according to a priority control.
