Abstract: Disclosed is an apparatus for spreading solid active agents and a method for controlling the apparatus. A boom is pivotably mounted on a vehicle. A sensor arrangement detects an angular velocity and/or an angular position of the boom about a pivot axis.

Approximately equal pressure levels prevail in the active pressure sides of two actuators operating in opposition or of a double-acting actuator, when the boom is stationary or moves only slightly in relation to the carrier vehicle. A defined differential pressure is adjustable between the active pressure sides of the actuators when the boom is shifted in relation to the carrier vehicle.

Abstract: Certain features relate to a centralized radio access network (C-RAN) that can flexibly and dynamically allocate protocol layer processing among baseband processing units and remote units. A C-RAN can be configured to include a media access control (“MAC”) scheduler and a fronthaul physical layer coordinator. The fronthaul physical layer coordinator can include a fronthaul physical layer scheduler, which can allocate spatial resources by determining the specific remote unit(s) that should serve a given mobile device. The MAC scheduler can allocate time/frequency resources to user devices communicating with the remote units. The fronthaul physical layer coordinator or the MAC scheduler can also determine the optimal transmission modes remote units can use to serve the user devices.

Abstract: Optical beam quality of an optoelectronic device is improved by suppression of high-order transverse optical modes by their resonant interaction with the continuum of modes in the surrounding regions, such continuum being realized by replacement of one or several layers by layers having a lower refractive index. In particular, selective oxidation of GaAlAs-based vertical cavity surface emitting laser results in (Ga)AlO layers surrounding the aperture and having a lower refractive index than the original (Ga)AlAs layers. The continuum of optical modes originates due to the modification of the optical field in the areas surrounding the aperture caused by the low index insertions positioned to result in enhancement of the optical field in their vicinity.
