Patent EP-0265194-A2 (EP)
Inventor: CASASENT DAVID PAUL
IPC: G06E3/00
Filed: 1987-10-19
Abstract: A Fourier transform optical processing method and system suitable for production line checking in which an electrical signal is generated by generator (2) in response to a first image and a beam (5) of coherent light is modulated by modulator (6) con­trolled by the electrical signal; a Fourier transform image (7) of the modulated coherent light beam is formed, and then detected by detector (8). The detector (8) provides a second electrical signal representative of the Fourier transformed image. Other aspects of the invention include comparing the second electrical signal to a reference electrical signal for producing an output signal representing any differences; optically preprocessing the image; detecting the Fourier transform image and generating signals representative of its Fourier transform charac­teristics; and modulating a coherent light beam using a liquid crystal or other spatial light modulating device.

Abstract: An electronic ignition circuit for an internal combustion engine produces an plasma arc across the spark gap of an ignition device. An a.c. circuit is formed of a push-pull inverter (30, 32) a center tap primary step up transformer (28) with feedback coil (44). A capacitor network (72, 74, 76, 78) passes pure a.c. to the primary of an ignition coil (95), so that the wave fed to the ignition device is free of any d.c. component. An impedance (102) connects to the breaker points or equivalent timing device to time the arcing so that an arcing a.c. voltage (106, 108) appears when the points are open, and a low voltage wave (110, 112) appears when the points are closed.

Abstract: The invention relates to a method for controlling brush­less d.c. motors and to a system for controlling such motors, by varying the effective value of current pulses to the phase windings. According to the invention, upon detection of a maximum current state the effective value is decreased by shortening pulses from a given time point (Ö1-Ö5) by the whole of the normally remaining part of the pulses, irrespective of whether the maximum current state ceases during the time that this part of the pulses should have occurred or not. This time point may coincide sub­stantially with the time point at which the state of maxi­mum current was detected or may coincide substantially with the later time point at which the duration of respective pulses exceeds a pre-determined minimum value. The next part-pulse is introduced at the time point at which it should normally have been introduced.

Abstract: A method of inputting to a program or virtual process information from an external source such as another independently running process of an I/O device. Information is transmitted to a program by means of events, which may be selectively retrieved from an event queue by the program. User input such as that from a keyboard or mouse-type device, is treated specially to insure that the input goes to the proper program in a multi-processing environment. A keyboard driver is included that has the capacity to use individual translation tables for each individual application program which is running. User input from user activated devices, such as a keyboard or mouse, are combined with input from other parts of the systems by an input funnel which insures that user input is routed to the proper destination. The input funnel operates in conjunction with a window manager to allow a user to type a sequence of keys which may be directed to several different programs which are running.

Abstract: This invention provides an apparatus for culturing animal cells, which comprises diagnosis means to make it possible to diagnose by measuring sizes of the cells by means of image processing while a system of culturing the animal cells is cut off from the outside of the apparatus system, control means to control the culture conditions of a culturing cistern on the basis of a result of the diagnosis, and culture medium re­generating means to remove waste contents in a culture medium. In the apparatus of this invention, the culture system and diagnosis system are cut off from the outside of the apparatus system. Therefore, no infection of miscellaneous microorganism, etc., occurs, nor does consumption of valuable cells and products occur. Further, since it is possible to easily obtain data of the proportions of division potential-possessing cells and living cells, the environmental factors to the culturing cistern can be easily and instantly controlled based on the data, and therefore, the culturing efficiency can be enhanced.

Abstract: Non-human mammalian cell lines which express antigens of the carcinoembryonic antigen gene family are provided by the present invention. The cell lines are prepared by gene transfection of human DNA, such as LoVo cell DNA, into non-human mammalian cells, such as mouse cells or by the transfection of complete cDNA in appropriate expression vectors into non-human mammalian cells, such as mouse cells. Primary transfectants can be transfected further into non-human mammalian cells to provide secondary transfectants. Cloning of secondary transfectants yields cell lines that exhibit increased expression of the surface antigen protein. The transfectant cell lines provide a means for producing antibodies, particularly monoclonal antibodies, against CEA family antigens. Furthermore, a general method is provided for screening and assessing the specificity of these antibodies to each member of the CEA gene family.

Abstract: The telephone line loop current regulator combines the functions of current regulation, current detection, loop disconnect signalling and speech switching. It comprises a gyrator circuit formed by resistor (R1), capacitor (C1), transistor (T1) and resistor (R3). Loop current is regulated by transistor (T1) and resistor (R3) while loop current detection is achieved by monitoring the voltage across resistor (R3) by an opto-diode which forms part of an opto-electronic coupler (OP2). Speech switching is performed by transistor (T3) which also monitors the voltage across resistor (R3) so that speech is switched onto the line via transformer (TR1) when d.c. loop current is present. Line seizure and loop disconnect signalling is carried out by switching the opto-coupler (OP1) to turn the transistor (T1) on and off.
