Abstract: Systems, methods, software, and data structures that provide dynamic lighting are described herein. The light sources, or other position-dependent devices may be paired to a device controller using near field communications (NFC) or other extremely short range radio technology, to share both pairing information and position information in a unified process.

Abstract: Systems and methods for managing device controls are disclosed. One method can comprise receiving validation information regarding validity of a plurality of command codes and identifying one or more code indices based upon the received validation information. If the one or more of the code indices is a full function match, the one or more of the code indices can be transmitted to the control device. If the one or more of the code indices is a partial function match, supplemental validation information can be requested regarding validity of one or more second command codes.

Abstract: A method for reliably avoiding backflow in the transport of a liquid under pressure via a transport pipe (1), in which a shut-off device (2) with differential pressure switching is arranged, into a container (3) which is under pressure and which comprises the liquid to be transported and/or another liquid is proposed, wherein a pressure accumulator (4) which is filled with the liquid to be transported up to a certain level and above the liquid level, in direct contact with the liquid to be transported, with an inert gas is arranged in the transport pipe (1) upstream from the shut-off device (2) in the transport direction, the inert gas being provided in the pressure accumulator (4) under an excess pressure and in an amount relative to the container (3) to be filled which are designed so that, in the case of a drop in the pressure in the transport pipe (1), the inert gas ensures a positive pressure difference in the transport pipe (1) to the container (3) over a period which is at least as long as the reaction
