Abstract: The invention relates to a method for recognizing identification media in the communication area of a write/read device functioning according to the principle of inductive coupling in the MHz range, wherein an antenna is used for transmitting and receiving HF signals, in addition to a circuit for transmitting HF signals with a standard transmitter power output and a logic circuit for evaluating communication between a write/read device and an identification medium. A short inquiry signal consisting of several fundamental components of the HF field and having a standard transmission power output is periodically transmitted via a transmission path and the antenna and a response signal is detected on the antenna. The response signal is compared to a reference signal and a communication signal is transmitted in order to recognize an identification medium in the event that the response signal is different from the reference signal.

Abstract: The invention relates to a transdermal therapeutic system (10) comprising a pharmaceutical active agent formulation (13), an adhesive layer (11) comprising a contact surface (12), and at least one ultrasound transmitter (21), the side of the ultrasound transmitter opposing the contact surface being directly or indirectly adjacent to the pharmaceutical active agent formulation.

Abstract: A transdermal therapeutic system (TTS) that is essentially composed of two compartments and is provided with activatable oversaturation and controlled permeation promotion. The invention more particularly relates to a TTS wherein an oversaturated active ingredient solution is produced in an active-substance-containing polymer matrix when the system is applied to the skin, caused by the controlled supply of one or several substances promoting the permeation of the pharmaceutical active ingredient; to the two compartments from which the inventive transdermal therapeutic system is assembled; and to the production of the transdermal therapeutic system from the two compartments.
