Title: Transmission active fiber-optic star coupler for a network system
Inventor: LIAW JY-WANG
IPC: H04B10/272
Filed: 1992-07-13
Abstract: A fiber-optic star coupler is configured by associating fiber amplifiers and passive fiber-optic star couplers to form a transmissive N*N active fiber-optic star coupler. The star coupler mainly contains 4*4 active fiber-optic star couplers and 2*2 3dB passive fiber-optic couplers acting as basic optical elements, wherein each of the 4*4 active fiber-optic star couplers is composed of six units of 2*2 3dB (or two units of 4*1 optical coupler), a dichroic coupler 27, an optical amplified fiber 28, and an optical isolator 29. By using a plurality of 4*4 active fiber-optic star couplers and 2*2 3dB passive fiber-optic coupler, it is possible to configure any desired configuration of transmissive N*N active fiber-optic star coupler. The number N may be any integral power of 2. The coupler in such a configuration uses less pumping sources and associated optical elements, and has the advantages of compensating the splitting loss and excess loss of the coupler, and therefore making it possible to expand the amount of connected terminals. As a result, the cost of the coupler may be reduced by 60% comparing to that of the prior art. In addition, the coupler can adapt to various pumping sources with different wavelength to meet the real demands and conditions of the network system. <IMAGE>

Title: Two part casing for a flat small blower
Inventor: AMRHEIN WOLFGANG
IPC: F04D25/06
Filed: 1992-09-28
Abstract: A small blower comprising a brushless direct current motor having a disk rotor (7) carrying a permanent magnet (10) and flat coil stator windings (5). The rotor (7) rotates an impeller (8).

The second part is a one-piece, moulded carrier plate (2) which supports the motor and impeller and the circuit board (4) and may be provided with integral resilient suspension means 30 for the motor. <IMAGE>
Patent GB-2265293-A (GB)
Title: Dung scraper systems
Inventor: O'DONOVAN JOHN
IPC: A01K1/01
Filed: 1993-02-05
Abstract: A yard scraper system has a scraper with a carriage (12) moving on a reciprocating rail (6) with teeth (7). Movement of the carriage (12) is caused by a tooth (7) pushing against a catch member (13) having pivot pin mounted in the carriage (12), and a free end engaging the tooth (7). When the carriage (12) reaches the end of the rail (6) the catch member (13) is suspended freely above the ground and on the next forward stroke of the rail (6) the last tooth (7) pushes the catch member (13) outwardly. It thus engages behind the catch member (13) so that on the reverse stroke it pushes it back and each successive tooth pushes the carriage (12) in the reverse direction. Because the teeth (7) effectively push the carriage (12) via the catch member (13), if an obstruction such as an animal is encountered the carriage (12) is simply pushed upwardly until the catch member (13) is disengaged and injury is not caused to the animal. <IMAGE>

Title: Method of making semiconductor laser
Inventor: KENZO MORI
IPC: H01S5/00
Filed: 1993-05-14
Abstract: The laser includes a first conductivity type semiconductor substrate (1); a double-heterojunction structure including a first conductivity type cladding layer (2), an active layer (3), and a second conductivity type cladding layer (4) successively disposed on the semiconductor substrate (1); two parallel grooves for forming the double heterojunction structure in a mesa stripe; a first conductivity type layer (5). a second conductivity type current blocking layer (6), and a first conductivity type current blocking layer (7) successively disposed on the semiconductor substrate (1) and contacting opposite sides of the mesa; and impurity doped regions (13) formed by adding an impurity from the surface of the first conductivity type current blocking layer (7). The impurity doped regions (13) electrically separate an upper part of the mesa from the second conductivity type current blocking layer (6) at opposite sides of the mesa. Since the second conductivity type current blocking layer (6) is not in contact with the mesa structure, no leakage current path is formed in the laser structure. <IMAGE>

Title: Tripping device for a safety device for protecting vehicle occupants.
Inventor: TSCHASCHKE ULRICH
IPC: B60R21/01
Filed: 1993-08-17
Abstract: The safety device (lateral air bag) protects vehicle occupants in the event of a side crash. To effectively avoid spurious tripping, the signals of a deformation sensor 3 arranged in the lateral region of the vehicle, and of a transverse acceleration sensor 6 arranged on the vehicle longitudinal axis are evaluated. In the event of the presence of a deformation signal an acceleration evaluator (integration) 14 is started and the tripping sensitivity is increased. It is provided, furthermore, that it is possible to determine the deformation rate from the signal of the deformation sensor, and that the increase in the tripping sensitivity is the stronger, the higher the deformation rate. <IMAGE>

Title: Separating a foreground picture signal from a mixed picture signal
Inventor: GEHRMANN RAINER
IPC: G06T7/00
Filed: 1994-02-04
Abstract: In a method of separating a foreground picture signal FG from a mixed picture signal MG which has a key color KC as well as transition colors to this key color in key regions, the foreground picture signal is removed from the key color and the transition colors in accordance with the equation  FG = MG - k * KC. Herein, k is a control signal which has a value of about 1 in the region of the key color KC and a value of about 0 at the transition boundaries. The transition boundaries in the Cb/Cr color plane are constituted by two straight lines through the origin of the Cb/Cr color plane which, relative to a vector DKC of the key color extending from the origin of the Cb/Cr color plane to the color location KC of the key color, are arranged at angles  omega o and omega u respectively. The straight lines through the origin of the Cb/Cr color plane are arranged automatically and optimally in that those pixels are filtered from the mixed picture signal whose color locations in the Cb/Cr color plane are spaced apart by a distance which is smaller than a predetermined distance from color locations of one or more pixels adjoining one another with respect to time or location, in that the angles  omega o and  omega u of the two straight lines through the origin of the Cb/Cr color plane are chosen to be such that the accumulations of the filtered pixels closest to the key color KC in the Cb/Cr color plane are not located in the region between the key color KC and the transition boundaries constituted by the straight lines through the origin of the Cb/Cr color plane. <IMAGE>

Abstract: A lining strip cutting machine has a flat board 30 for cylinder-shaped cloth 5 to lie on and to be moved across. A transmission assembly 20 rotates a transferring rod 40 at one side of the board to drive the cloth. The transmission assembly also drives an upper cutting wheel 80 a lower cutting wheel (90, Fig. 3) and a winding roller 701 which holds the cut cloth. A guide rod 50 at the other side of the board is adjustable in its angle to the flat board by means of a micro adjuster (1, Fig. 4) to let the moving cylinder-shaped cloth move incliningly nearer to the cutting wheels to enable a lining strip to be cut off the cloth moving around the flat board. The transferring rod the guide rod and a cloth stretcher 2 stretch the cylindrical-shaped cloth to let the cloth move around in stretched condition for cutting wheels to cut correctly the right size of a lining strip. The winding roller contacts a strip shaft to pick up a cut lining strip from the cutting wheels to push onto the strip shaft to be wound thereon. <IMAGE>

Abstract: Biocide concentration in industrial process water, e.g. cooling water in towers or aircon system water, is monitored by (a) assaying the biocide concentration in a sample using bioluminescent microorganisms and (b) assaying the level of living biomass in a sample. Microorganisms used in (a) may be a photobacteria whose reduction in luminescence is measured on addition of the water sample and assay in (b) is typically based on an ATP measurement using a luciferin/luciferase system. Kits for carrying out the steps (a) and (b) are also claimed. Measurements give the level of biocide in the water and also its overall bacteria level thus showing whether or not the bacteria are proliferating.
