Title: Theft protection system for motor vehicle
Inventor: SCHWEIGER JUERGEN
IPC: B60R25/02
Filed: 1996-07-30
Granted: 1997-09-25
Abstract: The system has a portable first code transmitter (1) which , when activated, transmits a coded engine starting signal (2) via a transmitter unit (20). A receiver unit (4,5) in the vehicle receives the signal and compares it with an anticipated coded signal.  If the signals coincide an engine (7) starting control signal is generated. A central control unit (15) in the vehicle only allows the vehicle to be used or driven when a release signal received by the control unit coincides with an anticipated desired release signal, whereby the release signal is generated by the code transmitter, or by a further code transmitter (17), from inside the vehicle.

Title: Transponder detection method e.g. for security tags, in region divided into at least two cells
Inventor: STOBBE ANATOLI
IPC: G06K17/00
Filed: 1998-06-02
Granted: 1999-11-25
Abstract: A field with a detectable characteristic is generated  in each cell (F1 - F4) by corresponding transmitters (S1 - S4). The field characteristic of a first cell is detected by a transponder which sends a response signal cyclically containing information about the detected field characteristic, i.e. that of the field in the first cell, the adjacent cell or that of an unknown field, which is compared with the cell characteristics to determine possible transponder positions.   The method involves detecting transponders in relation to overlapping cells (F1-F4) of the detection region.  A field is generated with a detectable field characteristic in each cell.  The field characteristic of a first cell is detected with a detector unit associated with a transponder.  A response signal sent cyclically from the transponder and received by a receiver unit contains information about the detected field characteristic, i.e. that of the field in the first cell, the adjacent cell or an unknown field characteristic.  The detected characteristic is compared with the cell characteristics to determine the possible transponder positions.  The position is verified, whereby after detection of a transponder in the first cell the field characteristic of an adjacent cell is set so that it is different from that of the first cell. Independent claims are also included for an arrangement for implementing the method and an application of the arrangement to detecting the position of a transponder used as a goods security tag.

Abstract: FIELD: development of oil deposit in monolithic stratum. SUBSTANCE: method includes pumping in working agent through injection wells in unsteady mode and oil extraction through producing wells. Distribution of current oil saturated beds is determined and current value of oil saturation gas pressure is detected at late stage of deposit development. Wells flooded to a level close to limiting one located in edge areas with lowered values of current oil saturated beds are developed at regular intervals. Wells located in ares with increased values of current oil saturated beds are developed under conditions of high-speed liquid extraction and bottom pressure below current value of gas saturation of oil. Once flooding close to limiting one has been achieved in wells located in the area of increased current oil saturated beds and edge area, one may reveal intervals with failed to be extracted oil deposits in opencast collieries of this wells. Isolation of perforated area is carried out in wells with the intervals like this followed by perforation of intervals comprising loss of oil production, and these wells are developed at high-speed modes. Individual producing wells with open intermediate beds including oil failed in being displaced after achieving limiting flooding are changed over for injection of working agent with selective perforation opposite intermediate beds identical to intermediate beds comprising oil in opencast collieries of adjacent developed wells. EFFECT: increased oil production. 2 cl
