Abstract: A method for processing glass is provided. The method includes the steps of providing a glass element and removing glass material from the glass element by etching with an alkaline etching medium in an organic solvent.

Abstract: A message distribution apparatus and method for distribution of a message submitted by a user by a terminal connected to a communication network to a previously unknown group of receiving users has an access to a database which stores a semantic network data model with terms linked to each other by semantic relations and/or a social network data model with users linked to each other by social relations; a mapping engine which maps at least one term being associated with the submitted message to terms being associated with users of the social network data model and/or with terms of the semantic data model for generating a group of potential receiving users for the submitted message; and a distribution engine which distributes the submitted message of the submitting user via the communication network to a group of receiving users filtered from the at least one generated group of potential receiving users.

Abstract: The invention relates to an RFID transponder which can be operated passively. It is the object of the invention to provide RFID transponders which can be operated passively in the far field, this means over distances of at least 15-20 cm, and which can be manufactured with reduced effort and costs in miniaturized form. In the RFID transponder in accordance with the invention, at least one antenna and one integrated RFID circuit are present on a substrate, The at least one antenna is in this respect included in the form of a dipole antenna and/or patch antenna in the same silicon block, as the substrate, as the integrated circuit. The at least one antenna is in this respect arranged at a minimum distance from the integrated RFID circuit and this minimum distance depends on the respective operating frequency.
