A method for providing a service provides for a service provider to provide information to a service demander. In order to produce the information, the service provider evaluates data that describe selected parameters along a journey route. The data from the selected parameters are obtained by the service provider from selected data providers for the purpose of evaluation. The data from the selected parameters are received by service provider from the selected data providers such that identification by the service provider of one of the data providers on the basis of the transmitted data is made more difficult.

An electronic circuit includes a floating gate transistor with a floating gate capacitor. The floating gate transistor can be programmed to be in an ON or an OFF state by charging the floating gate capacitor. The circuit further includes a deactivation capacitor adapted to store a charge sufficient for deactivating the floating gate transistor temporarily. The deactivation capacitor is connectable in series to the floating gate capacitor. A method for deactivating a floating gate transistor temporarily is provided, wherein the floating gate transistor includes a floating gate capacitor. A deactivation capacitor is charged with a charge sufficient for changing the state of the floating gate transistor temporarily. The deactivation capacitor is connected in series to the floating gate capacitor for deactivating the floating gate transistor.

A modular oxygen supply system is provided comprising at least one module skeleton with a baseplate with frames arranged in parallel to one another. The system includes supply lines for ambient air with air connections for taking off the air, first gas lines for oxygen with first gas connections for taking up the oxygen and second gas lines for outgoing air with second gas connections for taking up outgoing air. Rack guides with data lines are provided. At least one individual module can be pushed into the module skeleton. Each individual module has at least one molecular sieve container fastened on a baseplate with the gas connections and with an electric contact. Each individual module has a gas treatment unit for the ambient air fed in. A pressure reducer and a multiple-way valve as well as an oxygen reservoir are arranged downstream of the molecular sieve container or containers connected in parallel. Each individual module is pushed into the module skeleton and is connected via the gas connections to a supply line for the ambient air, to a first gas line for oxygen and to a second gas line for the outgoing air. The electric contact of the individual module is connected to the data line of the module skeleton.

An apparatus for supplying respiratory gas to a parachute jumper includes a mask which can be worn by the parachute jumper and a first respiratory gas reservoir includes a pressurized-gas vessel containing respiratory gas. The pressurized-gas vessel has an adjustable metering valve for metering respiratory gas contained in the pressurized vessel. A breathing hose connects the metering valve to the mask for conducting the respiratory gas to the mask. A second respiratory-gas reservoir contains a solid-state oxygen generator and has a manually-actuable starting device for the solid-state oxygen generator. The second respiratory-gas reservoir is connected to the breathing hose.
摘要:
Transponder signal collision avoidance system incudes a reader and wireless HDX or FDX type transponders (A, B) are disclosed, interrogated by the reader (R) by alternately powering and then reading through cycles corresponding to a number of possible transponders in the interrogation field. The cycles, which include reader power pulses, signify addresses of respective possible transponders, whether in or out of the field. The transponders for this purpose count reader power pulses by end-of-burst detection, increasing a stored count value with each reader power pulse. The transponder responds to the reader by transmission if and only if a stored count value in a read cycle matches a respective transponder address, preventing the transponders from transmitting telegrams interfering with each other. As a method of reader-transponder operation, the collision avoidance scheme thus cycles the reader interrogating through cycles having power pulses according to possible transponders in the field, not only calling the addresses of each of respective possible transponders but also shortening or lengthening read and power steps dependent upon responses received from the transponders.
