Title: Interception of wireless communications
Inventor: DIKMEN CEMAL TAMER
IPC: H04M7/00
Filed: 1999-10-30
Granted: 2001-07-11
Abstract: Method and apparatus for conducting surveillance in a SS7 intelligent network (IN) or advanced intelligent network (AIN) provides in the case of AIN that an info analyzed trigger is armed in an end office switch and notifies a delivery function when a call is processed. The delivery function instructs the end office switch to forward the call to the delivery function, where it is accessed for monitoring forwarded back to the end office switch. A similar method is used to process calls received by the SUS. In the case of IN, the identity of a line card assigned to a subscriber under surveillance (SUS) is changed to a number dedicated to surveillance subjects. Calls originated by the SUS are forwarded to a delivery function, which identifies the SUS based on the dedicated number of the calling party, intercepts call content, and forwards the call back to the end office switch with the called party id and the original number and id of the SUS. The end office switch then completes the call. A similar method is used to process calls received by the SUS.

Title: Surface treatment of semiconductor substrates
Inventor: KITTLE PAUL A
IPC: H01L21/00
Filed: 1999-12-03
Granted: 2001-04-11
Abstract: Surface cleaning, chemical treatment and drying of semiconductor substrates is carried out using foam as a medium instead of a condensed phase liquid medium. In cleaning and chemical treatment, by introducing a foam into an overflow vessel the foam is caused to pass over the substrate in moving contact therewith. Drying of the substrate is carried out, using a water solution of carbon dioxide in a pressurizable vessel. By releasing the pressure in the vessel, a layer of foam is established on the surface of the solution. The solution is discharged from the vessel, causing the foam layer to pass over the substrate in moving contact therewith. The carbon dioxide reduces the surface tension of the water, thereby enabling the foam layer to be produced and also assisting in the elimination of water from the surface of the substrate. In both cases, the use of foam reduces materials requirements and also reduces the quantity of particles deposited onto the substrate in the treatment process.

Granted: 2002-02-21
Abstract: Provided is an optical information recording method and apparatus for recording information while maintaining the direction in which a laser beam is emitted even if the information recording surface of an optical information recording medium is tilted. In performing OPC, the relation (reference equation) between the recording power and the asymmetric value, the relation (first measurement equation) between the differential light intensity value and the recording power, the relation (second measurement equation) between the difference between the differential light intensity value and the reflectance and the recording power, the relation (third measurement equation) between the reflectance and the recording power, the differential light intensity value, the recording power, and the reflectance at which optimum asymmetric value is set up are found and stored. In performing actual information recording, the recording power is corrected so as to always set up an optimum asymmetric value by using these relations. Hence the reduction of the illuminance per unit area due to tilt of the information recording surface can be compensated without correcting the direction where the laser beam is emitted.
