Abstract: The invention relates to a method for establishing a communication link between communication terminals (KEB1, KEG2, KEG3) which are associated with a preselected group (G) of communication terminals. According to said method, a start message 1 is captured by a server (S1, S2) of a communication link (KN1, KN2), which is sent by the communication terminal (KEG3), the preselected group is determined by the server using information transferred in the start message via the communication terminal (KEG3) and is associated with the communication terminal (KEG3). Also, a link message (2) is transferred by the server (S1, S2) to the communication terminal (KEG3). The server (S1, S2) captures a link confirmation message (3) which is sent by the communication terminal, whereby the communication link between the communication terminal (KEG3) and additional communication-ready communication terminals (KEG1, KEG2) of the group, is produced. The invention also relates to a server.

Abstract: The invention relates to a covering placed against the housing wall by means of a self-adhesive coating applied to the underside of the covering and covers the recess provided in the housing wall. An inner opening passing through to the inside of the housing is provided in the recess. A gas-permeable, however fluid-impermeable, diaphragm is glued over the inner opening. The adhesive coating applied to the underside of the covering is discontinuous in the area of the inner opening in order not to close the pores of the diaphragm. The outer opening is situated so that it is laterally offset from the inner opening, and is made in the covering while being completely delimited thereby.

Abstract: Methods for determining the resonant frequency for interrogation of a resonant device include steps for generating and coupling interrogation pulses of various bandwidths to energize one or more SAW resonator elements. Initial interrogation pulses have a relatively wide bandwidth, such that the general location of a resonant device's resonant frequency can be expediently determined. Then, interrogation pulses having smaller bandwidth pulses can be coupled to the resonant device at frequencies near the determined general location of resonance to further narrow the location of resonance. In some embodiments, one or more initial interrogation pulses are coupled to the resonant device at a frequency in the center of or at an expected value within an expected range of operation of a resonant device.
