Abstract: A method and system for monitoring the availability of medical aids for a patient. A first signal transmitter is mounted on the aid for transmitting first electromagnetic signals. A second signal transmitter is worn by the patient and has a warning device for outputting a warning signal which can be perceived by the patient. A receiving unit receives the first electromagnetic signals transmitted by the transmission unit. A control unit actuates the warning device to output the warning signal when the first electromagnetic signal is received and when a predetermined reception strength for the first electromagnetic signal is undershot and when a particular item of information associated with an operative state of the medical aid is transmitted with the first electromagnetic is received.

The warning system comprises a first signal transmitter, which can be mounted on the aid or on a container for the aid or can be integrated in the aid or container and which has a transmission unit for transmitting first electromagnetic signals, and a second signal transmitter which can be worn by the patient and which has a warning device for outputting a warning signal which can be perceived by the patient, a reception unit for receiving the first electromagnetic signals transmitted by the transmission unit in the first signal transmitter, and a control unit which, when the first electromagnetic signals are received or when a prescribable reception strength for the first electromagnetic signals is undershot and/or when a particular item of information transmitted with the first electromagnetic signals is received, actuates the warning device to output the warning signal.

Abstract: A method for detecting a biochemical reaction includes immobilizing a capture molecule on an inner wall of a pore selected from a multiplicity of pores extending between first and second opposed surfaces of a macroporous substrate and contacting an analyte with the capture molecule. A light is then directed into the pore. A change in a light transmission property of the pore is then detected. This change indicates a binding reaction between the analyte and the capture molecule.

Abstract: An integrated circuit having capacitive elements for smoothing a supply voltage is described. In this case, at least one additional metal electrode, which is configured as a high frequency-optimized capacitance and is distinguished by an extremely low sheet resistance, is connected in parallel with the MOS capacitances. By connecting the areally highly effective MOS capacitance, which, however, is connected with a somewhat higher impedance, in parallel with areally less effective metal capacitances, which, however, are connected to the supply voltage in a very low-impedance manner, it is possible to obtain broadband buffering and thus decoupling of high-frequency interference signals. Very high-frequency interference components are attenuated on the chip and do not pass into the system surrounding the integrated circuit.

Abstract: A method and apparatus in which the switching of a field-effect transistor is effected by the application of a control voltage suitable for switching to an RC element connected upstream of the gate terminal. The method and apparatus are distinguished by the fact that switching of the field-effect transistor is carried out using a control voltage that at least temporarily only slightly exceeds the threshold voltage via an attenuation circuit which has to be applied to the gate terminal of the field-effect transistor in order to be able to effect switching of the transistor.

Abstract: The invention relates to a bus driver having an inverter for driving a preferably clocked signal on a bus line. In the event of a capacitive coupling of the bus line to at least one neighboring bus line, a number of secondary inverters corresponding to the number of capacitively coupled bus lines are connected in parallel with the inverter of the bus driver. A simple logic combination supplies the necessary activating signals for the parallel connection of the secondary inverters. As a result, an additional secondary inverter can be connected in when an opposite edge occurs on a neighboring line for the instant of the edge. The invention consequently enables the driver intensity to be adapted dynamically to the signals of neighboring capacitively coupled bus lines.

Abstract: The integrated circuit is provided with capacitors for smoothing the supply voltage. The capacitors are disposed below the supply interconnects which supply the integrated circuit with the supply voltage. This enables the integrated circuit to be accommodated on a minimal area.
