摘要:
A payment method (BV) executed by a communication facility (1, 2, 8, N) and at least one data carrier (11, 12, K) for debiting a payment value unit (BW) from the data carrier (11, 12, K), in order to pay for a performed service, wherein the following steps are executed: debit from a memory value unit (SW) stored in the data carrier (11, 12, K), of a debit value unit (AW) sufficient for payment for the maximum service to be performed, wherein a repayment limit (RL) stored in the data carrier (11, 12, K) is set to the value in essence of the debited debit value unit (AW); calculation of a credit value unit (AWE) to be credited back, wherein the payment value unit (BW) to be paid for the actually performed service is subtracted from the debited debit value unit (AWE); check by the data carrier (11, 12, K), that the credit value unit (AWE) to be credited does not exceed the stored repayment limit (RL), wherein only in this case is the credit value unit (AWE) credited to the memory value unit (SW) stored in the data carrier (11, 12, K).

A communication device has a socket 41 for connection to a plug 47 of an external acoustic transducer device 35, 37. The communication device includes a phone chip 101 for communicating with the external acoustic transducer device via the plug and socket. The phone chip 101 has an interface 39 electrically connected to the socket, and is enabled to detect an impendence between at least two contacts of the socket, and thereby determine if the socket is connected to the plug. Typically, this test is carried out at intervals, and when it is carried out according to the result of the determination, generates an interrupt signal that can modify how the phone chip 101 operates the interface 39.

In the case of devices with a program-controlled circuit arrangement operating program instructions are necessary for their operation. In order to reduce the storage space necessary for this, in the case of devices which have a connection (6) to a data transmission network (7) in any case, the operating program instructions are not held in the device, but loaded via the data transmission network (7). For this purpose the circuit arrangement (1) has a start procedure memory (3), in which is stored a start procedure set up in such a way that for its execution a processor unit (2) connects up via the data transmission network (7) by means of the interface (6) to an operating program server and from this loads operating program instructions into a main memory (5) connected to the processor unit (2). The storage space required for the start procedure memory (3) can be further reduced, if the start procedure embedded in it is set up so that the processor unit (2) loads the instructions, which are necessary for connecting to the operating program server and for loading from this the operating program instructions, from a download procedure memory (4).

In a particle projection lithography system, an alignment system is used to determine alignment parameters to measure the position and shape of an optical image of a pattern of structures formed in a mask and imaged onto a target by means of a broad particle beam, by means of an apparatus with a plurality of alignment marks adapted to produce secondary radiation upon irradiation with radiation of said particle beam. In order to allow for a variation of the alignment parameters along the optical axis, the alignment marks are positioned outside the aperture of the alignment system for the part of the beam that generates said optical image, arranged at positions to coincide with particle reference beams projected through reference beam forming structures provided on the mask while said optical image is projected onto the target, and situated on at least two different levels over the target as seen along the directions of the respective reference beams.
