Abstract: A system and method for remotely triggering a predetermined program at a host computer system using a telephone ring signal is disclosed. The host computer system includes a ring detection and triggering circuit, a control monitor program, and at least one activation script, wherein the activation script could be a series of commands which create a connection between the host system and the Internet. A ring signal on a phone line connected to the host system is detected by the ring detection circuitry, and subsequently a trigger signal is generated by a trigger circuit which is detected by the control monitor program running on the host system. The control monitor program responds to the trigger signal and executes the activation script, thereby causing a connection to be established between the host system and the Internet. Other features, such as multiple activation scripts, remote user authentication, and feedback validation tones are also disclosed.      Further disclosed is a method of operating an ISP server computer for detecting whether a connection is being requested of a customer's host computer system, of determining whether the host computer system is presently connected to the Internet, and if the host system is not connected, of dialing a phone number which triggers an activation program stored at the host system, thereby causing the host system to connect to the Internet so that it can be accessed.

Abstract: A side-looking NMR logging tool incorporates a permanent magnet arrangement (1) having a magnetization direction oriented towards a side of the tool and a dipole RF antenna (10) displaced towards the front of the tool. The magnetic arrangement produces a shaped region of investigation in front of the tool wherein the magnetic field has a uniform field strength and the RF field has a uniform field strength in a direction orthogonal to the static field. The shaping of the static field is accomplished by the magnet arrangement comprising a plurality of magnets (8) having parallel magnetization or by a single shaped magnet (8). The antenna arrangement includes gapped core made of non-ferritic soft material for increasing antenna efficiency. The magnet arrangement also reduces ringing in the core and the antenna. An optional RF  shield is used to reduce NMR signals from borehole fluids.

Abstract: In a method for the catalytic oxidation of a gas, the required expenditure should be kept as low as possible even with a reliable treatment of comparatively large amounts of gas and/or high concentrations of gas portions that require treatment. To this end, according to the invention, a gas flow (G) comprising the gas to be treated is circulated via a reaction zone (4) and via a reflux zone 6 communicating with it at the inlet and outlet end. An especially effective maintenance of the circulation of the gas flow can be obtained thereby in the manner of a passive system by preferably conveying the gas flow (G) comprising the gas to be treated in the reaction zone (4) in an upward direction and by assisting the upward flow convectively by means of the heat released during the oxidation reaction. Furthermore, the gas flow (G) is preferably cooled locally in the reflux zone (6) by spray cooling.

Abstract: A method for selectively maintaining compression state and applying a compression technique after a PPP renegotiation on a Um interface of a wireless communicaiton network. A communication device (104) receives packetized data transmitted from a terminal device (102), which is coupled to the communication device via an Rm interface. The communciaiton device determines (S315) whether the received packetized data comprises compressed or uncompressed data. Upon determining that the received packetized data comprises compressed data, the communicaiton device determines (S340) whether connection information exceeds a highest-numbered decompression slot from a plurality of decompression slots on said Um interface. The communciation device sets up (S330) a local decompression slot, int he communicaiton device, which corresponds to the connection information in order to maintain said compressionsate, wherein the local decompression slot is set up in response to determining (S325) that the connection information exceeds the highest-numbered decompression slot. The communication device decompresses (S350) the compressed packetized data when it receives compressed packetized data containing said connection information.
