Patent EP-0315051-A2 (EP)
Inventor: FANT KARL M
IPC: H04N7/24
Filed: 1983-07-27
Abstract: A computer controlled digital imaging process system is devised which operates to compose and construct a sequential stream of scenes for a 2-dimensional display from a library of images of objects such as trees. The processing speed is sufficient to permit a real-time, or near real-time, analysis of the images by a human operator or a hardware/software equivalent thereof. The images of objects stored in the library are in rectangular form. 
     A vehicle such as a helicopter simulator has a field of view which represents what is seen through the "windshield" thereof which in the simulator is the screen of a computer monitor. A perspective mapping process is provided for mapping images of objects which appear in the field of view from the corresponding images in the library to the face of the monitor screen. The four corners of a stored image are located by calculations in the face of the monitor screen and the mapping of rows and columns of a stored image is done in two passes or stages. Whereas linear mapping involves the linear conversion of pixel lengths, the perspective mapping herein makes such conversions on the basis of different parts of the object being different distances from the "windshield" or face of the monitor screen and thus the more realistic effects of a perspective view are achieved.

Abstract: For positioning workpieces, e.g. steel-sheet billets, relative to the work station of a punching machine, coordinate tables are known which interact with CNC drive devices and consist of a lower carriage which is movable in a first direction and in turn carries an upper carriage which is movable in a second direction running at right angles to the said first direction. The upper carriage carries clamping tools which serve to take hold of the workpiece resting on it. To avoid scratch and abrasion marks on sensitive workpieces, which can arise as a result of relative movements between the workpiece and its bearing surface on the coordinate table, and for simple manipulating capacity of the workpieces, a coordinate table according to the invention is characterised in that the workpiece-bearing surface is formed by a preferably uniform distribution of bristles (14) which in their entirety form a workpiece-bearing plane (22). Apart from reliable, damage-free support of the underside of the workpieces, the means of simple manipulation of the workpieces by means of clamping grips is obtained, which clamping grips can reach beneath the workpiece resting on the said bristles (14) while the latter are elastically deformed. <IMAGE>

Abstract: To simplify the assembly of articles to be fastened to a wall, such as for example sanitary fittings, with two or more holding parts 4 fitted with screw holes, it is proposed that an adhesive strip 4 or the like, coated on both sides and covering the screw holes 42 and having markings 51 corresponding to the screw holes 42 is arranged on the wall-side contact surface 41 of each holder 4, the adhesive effect of the wall-side coating of said adhesive strip being substantially stronger than the adhesive effect of the fastening-side coating. For the assembly, an article of this type is pressed with its holding parts on the previously determined place on a wall or another fastening base and then removed again. Due to the stronger adhesive effect of the wall-side coating, the adhesive strip 5 remains on the wall. The bore holes are introduced through the adhesive strips 5 into the wall or the like situated below it. <IMAGE>

Abstract: All subscribers operating within a communication system initially generate and transmit a random password and their ID code to the operation (control) center of a communication system. Thereafter, in a first embodiment, subscribers are commanded to modify (in a predetermined manner) and re-transmit their password and ID code either periodically or upon requesting access to the communication system. The modified password is retained as the current (authorized) password by both the subscriber and the system. In a second embodiment, subscribers are commanded to generate and transmit a new random password and their ID code to the system, which maintains a history of each subscriber's current and previous passwords. According to the invention, some of the subscribers having an unauthorized (duplicated) ID code may be inactive (off) when the subscriber is commanded to modify or generate a password. In this way, one of the subscribers having an unauthorized (duplicated) ID code will become out-of-sync with the system, and eventually transmit an unauthorized password. When the system receives an incorrect password for an out-of-sync subscriber, access to the communication system may be denied, and the subscribers that duplicate (or permit others to duplicate) ID codes may be identified.

Abstract: An assembled shaft, in particular a camshaft, drive shaft or crankshaft, having at least one tubular body and a plurality of elements, such as cams, gearwheels, bearing sleeves or crank cheeks, which are sealingly fixed to the body at a distance from one another by expansion of the same performed in longitudinal sections, has a tubular body which, given approximately constant wall thickness, has a reduced diameter in each case in the region between two elements. As a result of this, given suitable internal pressure loading in the entire tubular body, a plastic deformation of the sections of larger diameter opposite the drive elements to be fixed is possible, whereas the deformation of the tubular sections of smaller diameter lying between the drive elements remains in the purely elastic region. In an advantageous embodiment, sleeves of larger diameter compared with the tubular body are in each case provided between two elements, the ends of which sleeves are clamped between the tubular body in the region of larger diameter and the elements. <IMAGE>

Abstract: A plural channel indirect digital to analog converter. Words containing address bits and data bits are received on an input and entered into a specific one of the converter channels under control of the address bits of the word. The data bits are applied to a binary rate multiplier of the channel which generates a pulse modulated output signal representing the binary value of the received data bits. The pulse modulated output signal is applied to an associated filter which converts the pulse modulated signal to an analog output signal whose amplitude represents the binary value of the received data bits. Gating circuitry ensures that each output pulse is of a precisely controlled pulse width. One of the converter channels is used to calibrate the output level of the filters. The number of data bits applied to the different channels may need not be the same and may vary in number from a minimum of 1 to a maximum of m.

Abstract: A signal recording/reproducing apparatus equipped with a recording head section for recording signals on a recording medium and a reproducing head section for reproducing the signals recorded on the recording medium. The recording head section is arranged to record the signal to form N recording sub-tracks on the recording medium and the reproducing head section has M reproducing sub-heads which trace the N recording sub-tracks to reproduce the recording signal. The pitch of the M sub-heads thereof is equal to a pitch of the recording sub-tracks and the number M of the sub-heads is greater than the number N of the recording sub-tracks. The reproducing head section is coupled to a reproduction signal detecting section which in turn eliminates the interference and the crosstalk between adacent tracks from the reproduced signal due to the reproducing head section. This arrangement allows narrowing the track pitch to increase the recording capacity and extremely improving the transfer rate concurrently with the elimination of the the interference between the adjacent codes and crosstalk between the adjacent tracks.
