Title: Optical reduction of non-linear optical amplitude distortion
Inventor: BUELOW HENNING DR ING
IPC: G02B6/42
Filed: 1993-03-30
Abstract: Particularly in analog optical broadband transmission (CATV), stringent requirements are imposed on the non-linearity of the optical signal. It is known for the modulation signal to be electrically pre-emphasised or for the signal received in the receiver to be electrically equalised or for distortion to be prevented through the use of components with linear characteristics. In the invention, non-linear amplitude distortion of optical signals from polarised, wavelength-modulated light is reduced in an entirely optical manner through the arrangement of a polarisation setting (birefringent) component (PS) and a double-refracting medium (DM). The signal is fed via the polarisation setting component (PS) and the double-refracting medium (DM) disposed downstream to a receiver (E). The frequency spectrum of the electrical output signal of the receiver (E) is analysed and minimised through variation of the plane of polarisation of the light in the polarisation setting component (PS). <IMAGE>

Title: Multi-coloured rod for throwing and catching, having a fixed or variable centre of gravity, which can be used as a plaything in the leisure sector
Inventor: JUST EKKEHARD
IPC: A63B15/00
Filed: 1994-02-15
Abstract: The entire surface of conventional playthings for throwing and catching serves as a catching surface. In such playthings, it is immaterial at which point of its surface the plaything is caught. Because of their shape and their flight performance, the following idea is ruled out: Increasing the playing incentive by dividing the surface into a plurality of catching zones which are mutually distinguishable optically and between which the player can make a choice when catching. The novel, multi-coloured rod for throwing and catching offers this facility. By virtue of its shape, its multi-coloured surface design and its construction, this aspect of catching can be embodied. As a result of the option of the variable centre of gravity, the flight performance of the rod can be extensively influenced, so that a large number of levels of demand made upon the playing skill of the catcher result. The multi-coloured rod for throwing and catching can be used primarily in the leisure sector. Subsequent use as a form of sport and in competitions is also conceivable.

Title: Prodn. of test pattern for identifying transit time faults in logic circuit
Inventor: FUCHS KARL
IPC: G01R31/3183
Filed: 1994-03-16
Abstract: The gate plane is located between the input and output. the test path is divided in to at least two part test paths, to produce unambiguous "forking". Urgent necessary value applications are carried out directly for each part test path selected, for the spread of a signal value change. With each "forking" the hitherto test pattern prodn. status is stored. So that later in a further method step it can be recalled. If an output is reached, concluding signal value applications, not yet adjusted, are ensured by optional value allocations. Whilst a known back-track search method is used. With this, for different test path variants, which have common part test path, it avoids the compulsory carrying out of the urgent necessary multiple value applications.

Inventor: TANABE TOKUYOSHI
IPC: B23K26/38
Filed: 1994-07-28
Abstract: According to the invention, a ground sheet (51) is laid onto a backing sheet (52) and is then cut to a predetermined shape without the backing sheet (52) being cut. Embroidery is then produced along the edge of the ground sheet (51). A sewing machine with a laser-cutting system according to the present invention is provided with: a needle bar (31) which is movable in a vertical direction; a sheet-holding frame (75) which is movable in an X-Y direction; a laser oscillator (21) for the oscillating emission of laser light; and a sewing-machine table (61). For the cutting operation, the vertical movement of the needle bar (31) is stopped, the sheet-holding frame (75) is successively moved in the X-Y direction, and the laser oscillator (21) successively emits laser light in an oscillating manner. While the sheet-holding frame (75) is thus being moved successively on the sewing table, the ground sheet (51) is cut exactly in a prescribed shape by means of the laser light. Thereafter, for an embroidering operation, the needle bar (31) is moved in the vertical direction; the sheet-holding frame (75) moves intermittently in the X-Y direction, and it is synchronised with the vertical movement of the needle bar (31) and finally produces embroidery along the edge of the ground sheet (51). <IMAGE>

Title: Asynchronous motor efficiency measurement method
Inventor: BENNING WILFRIED
IPC: G01R31/34
Filed: 1994-09-26
Abstract: The method involves separating the copper losses, iron losses, friction losses and additional losses after determining (4,5) the power and current taken up by the motor (1) and taking into account the motor clamp resistance and slip. The shaft power is determined by subtracting losses from motor power. Efficiency is determined by dividing shaft power by motor power. An upper limit for the motor's characteristic efficiency is derived (9) by associating iron and frictional losses to standard losses and a lower limit by associating the iron and frictional losses to rotor losses for the unloaded motor state. Upper and lower limits for the loaded state are derived by associating iron and frictional losses as above, taking into account the copper losses derived from the unloaded state parameters, and define the range of efficiencies for the loaded motor.

Title: Sensor for the automatic release of passenger protection devices in vehicles
Inventor: HEINTZ FRIEDER
IPC: G01P15/03
Filed: 1987-02-25
Abstract: A sensor (11) in which the inner space (13) of a housing (10) is completely filled with gas (15) and with liquid (14). The gas (15) and the liquid (14) must not react chemically with one another or dissolve in one another, so that as sharp and precise an interface is created between the two media. When the housing (10) is diverted as a result of tilting or by a transverse acceleration, the reflective behaviour of an optical beam on the interface is modified. As a result, a control signal is generated which releases the passenger protection devices of a motor vehicle. With the aid of a single sensor both the position angle and transverse acceleration can be determined either individually or together.
