Abstract: A device for checking access permissions includes an access area with guidance devices for forming an access lane for separating people or objects, in which blocking and/or signal means define an access threshold. A gate controller having a Bluetooth radio interface allows an access permission to be read from mobile data carriers, and positive validation of the access permission results in the access controller releasing the blocking and/or signal means and thus allowing separate passage through the access threshold. An access lane has an associated multiphase antenna group, the transmission/reception antennas of which are actuated by a Bluetooth transceiver module via an antenna feed network in such a way that at least two antenna lobes form that are at different distances from the access threshold as seen in the direction of access.

Abstract: Providing a virtual acoustic environment comprises determining updates to audio signals based at least in part on information in sensor output, including, for each of multiple time intervals: determining an updated position of a wearable audio device, based at least in part on position information in the sensor output; determining layouts of at least four virtual walls, where the layouts are determined such that the updated position is within a space defined by the virtual walls; determining positions of at least four image audio sources associated with a virtual audio source, where a position of each image audio source is dependent on a layout of a corresponding one of the virtual walls and a position of the virtual audio source; and processing the audio signals using an update determined based at least in part on the respective positions of the virtual audio source and the image audio sources.

Abstract: The invention relates to a UHF RFID transponder with an antenna and an RFID chip, wherein the antenna has a first dipole structure, a first inductive loop and an infeed point, and the first dipole, the inductive loop and the RFID chip are electrically connected to the infeed point. The purpose of the invention is to create an RFID transponder that can be tuned with reduced influence from the geometric tolerances involved in the production of the antenna. As a result, these RFID transponders are intended to be particularly suitable for attaching to glass panes, as the impedance of the antenna can be tuned to the impedance of the RFID chip with less influence from the thickness or material composition of the glass. This task is achieved in that the antenna (2) has a second inductive loop (8) and that this second inductive loop (8) is electrically connected to the infeed point (3) and connected in parallel to the first inductive loop (7).

Abstract: An improved magnetically coupling near-field RFID antenna is embodied as a magnetic H-field coupler, and the near-field RFID antenna is embodied as a looped and/or frame-shaped antenna. The looped and/or frame-shaped antenna comprises a looped or frame-shaped strip conductor. The strip conductor is arranged set apart from a ground surface parallel thereto. A dielectric is interposed. The start and the end of the strip conductor end close to each other forms a gap or spacing. The start of the strip conductor is fed to ground. The end of the strip conductor is terminated by a terminating resistor. The terminating resistor is connected between the end of the strip conductor and a ground surface.
