Title: Vehicle theft protection device - has on-board transmitter continually transmitting vehicle identification code which receiver can be arranged to pick up on theft
Inventor: GEBAUER HERMANN
IPC: B60R25/102
Filed: 1992-05-16
Abstract: The protection device includes a transmitter integrated in the structure of the vehicle and an external receiver which corresponds to the transmitter when necessary. The transmitter permanently transmits a signal coded on the vehicle, at a predetermined rate. When it is called upon when the vehicle has been stolen, the receiver sorts the received signals from the coded signals transmitted from the vehicle. The receiving antenna has a club shaped characteristic or is a parabolic antenna with a circular radiation characteristic. Thus, when it is discovered that the vehicle has been stolen, the receiver communicates with the vehicle identification code and scans all the received data in the used frequency bands. It compares the scanned data with the vehicle ID code and announces when it is found. ADVANTAGE - Allows stolen vehicle to be recovered even when vehicle has been taken without operating the alarm.

Filed: 1992-09-02
Abstract: The computer of a control console of a machine, especially a printing press, with a hard-disk drive and a floppy-disk drive, is to be further developed in such a way that if the hard-disk drive fails immediate continued operation is possible. According to the invention it is provided that the computer has two hard-disk drives, but in normal operation only one hard-disk drive is the main drive. The storing and calling up of data is consequently performed only in connection with this first hard-disk drive. From time to time, either under program control or at the initiation of the user, backup copies of data of the first hard-disk drive are created on the second hard-disk drive. After failure of the first hard-disk drive (main drive), the computer can be switched over to the second hard-disk drive during booting after loading a special floppy disk, i.e. the user can continue to operate the machine by means of the control-console computer with this second hard-disk drive and the data updated by the last backup. After restoring the defective hard-disk drive or after fitting a new hard-disk drive, a transfer back of the data generated in the meantime on the second hard-disk drive to the new hard-disk drive is performed. This is expediently initiated again by part of a program on a floppy disk, which is to be loaded into the floppy-disk drive when the control-console computer is put into operation.

Title: Safety device for shooting weapons (firearms and archery weapons)
Inventor: KEPPELER DIETER
IPC: F41A17/70
Filed: 1993-04-02
Abstract: The safety device consists of a locking slide which can be moved manually from a safe position into a firing position and vice versa. The locking slide is additionally operatively connected via a driver to one or more inertia weights which are mounted such that they can be displaced. In the event of the armed weapon being accidentally dropped, the inertia weight is moved, by its inertia, by the impact on the ground and, via the driver connection, the locking slide is automatically moved from the firing position into the safe position, so that the weapon's sear is locked. This prevents it being possible for a negligent shot (accidental shot) to be fired from the armed weapon as a result of the shock when the weapon strikes the ground.

Title: Ground lying mat with head support/backrest capable of being turned out, and carrying bag
Inventor: DRIGNATH ROLAND
IPC: A47C9/10
Filed: 1993-04-21
Abstract: The invention relates in particular to a lying mat to be laid on the grass or a sandy beach, which, for a head support of desired height or backrest to be set at different angles, is equipped with a supporting device capable of being turned out via joints and a headrest capable of being pulled out, as well as with a built-in carrying bag. The ground support of the mat has a moisture-insulating covering, the insulation occupying a lateral extension beyond the actual width of the lying mat. Increased protection of the mat, for example against moist grass or sand, is thereby provided. For the design of the joints, two types of design are provided, namely either two snap-in joints or two screw-type joints. A headrest, consisting for example of a foam insert, can be pulled out by means of its insertion bars from the lateral support of the head support/backrest by the tripod method into the height desired in each case. To receive the ground lying mat, which can be folded up into a very small bundle, use is made of the space between the ground rest and the carrying bag arranged on the turned-in head support/backrest.

Title: Optimum detector for multi-channel measurement data
Inventor: STROBACH PETER DR
IPC: G01V1/36
Filed: 1993-06-21
Abstract: Method for the detection of signals in noisy multi-channel measurement data, in which a set of measurement signal vectors is measured with the aid of a set of sensors, each component of each measurement signal vector corresponding to a measurement of a sensor at a specific point in time, and in the case of which this set of measurement signal vectors is compared with a set of signal pattern vectors by determining from the set of measurement signal vectors and the set of signal pattern vectors a cross-correlation matrix whose maximum singular value is used for the detection as the measure for the distance. Compared with the known methods, this method has the advantage that correlations between the individual signals of a multi-channel measurement system are used in order to increase considerably the sensitivity of the detection in relation to known methods. In this way, the method is particularly suited for applications with very weak signals in very noisy sensor signals, such as for example for applications in magnetoencephalography. In the case of a 32-channel MEG, an increase in the sensitivity of the detection by a factor 3 to 5 can be obtained using the method. In this way, even extremely weak acoustically evoked MEGs can still be found without any problems. <IMAGE>
