Patent EP-0408232-A2 (EP)
Inventor: PIAZZA THOMAS ARPAD
IPC: G06T15/50
Filed: 1990-07-02
Abstract: In a computer image generation system, the number of vertices (V₁,V₂,V₃) which define polygons (10) is augmented (22,24,26) in real time for providing finer detail and for effecting smooth level of detail transition. Augmented vertices may have components that are statistically derived in which case it is not necessary to store and/or predefine them. Alternatively, some vertex components may have predetermined values derived from mapping data or from other deterministic sources and may be stored in compact form. Processing polygons defined by the augmented vertices along with the original vertices may be used for displaying the finer detail. Statistically derived finer detail is especially suited for providing non-specific detail to features such as terrain and bodies of water, while deterministic data allows highly accurate represent­ations of specific 'real world' locations. Vertex augment­ation may be controlled by the following breakup criteria: range from the viewpoint, angle from the viewpoint bore­sight, desired maximum error or other criteria and combin­ations thereof.

Abstract: An autoclave 1 has a water level sensor 20 in a water reservoir 5 in the pressure vessel 2. An external water tank 21 is connected to the reservoir via an electrically-operated valve 23. An electrical resistance heating element 6 in the reservoir 5 heats the sensor 20 if it indicates a full level at the start of operation, in order to dry any exposed part of the sensor and thereby prevent an erroneous output from the sensor caused by water clinging to it. This heating of the sensor can be repeated if it continues to indicate a full level. If a low level output is produced by the sensor 20, the valve 23 is opened to allow water to flow from the tank 21 to the reservoir 5. If the valve 23 remains open for longer than a predetermined time without the sensor indicating a full level, the autocalve produces a fault signal.

Abstract: The invention relates to a processing apparatus comprising an extruder and a calender for plates or sheets made from plastic or rubber, in which the extruder is provided with an extrusion head distributing widthwise the material to be extruded, moulding bars of the said head being removably fitted. It is the object of the invention to provide a simple way in a processing apparatus comprising an extruder and a calender of achieving a change in the length of contact of the bank on the roll circumference without exchanging pairs of bars. The invention consists in that either the extruder or a calender is set up horizontally immovably, and that between the extruder and the calender there is arranged a coupling means which permits a finely adjustable change in the spacing between extruder and calender in such a way that the distance of the moulding bars from the rolls of the calender in the roll nip can be changed from a minimum value, at which the moulding bars are virtually against the rolls, to a maximum value, at which the moulding bars may even be located outside the roll nip.

Abstract: An elongated or rectangular cross-section capillary 12 is disclosed for use in capillary electrophoresis using optical detection 10, 14. With rectangular capillaries, heat is efficiently dissipated which permits large volume applications in capillary electrophoresis. In addition, the increase in cell pathlength between the source 16 and detector 18 produces significant improvements in absorbance detection sensitivity. This advantage is also important for laser-induced fluorescence, optical rotation, and other pathlength-dependent detection schemes. Because flat walls produce less optical distortion than circular capillary walls, rectangular capillaries are particularly useful when parameters such as refractive index, photodeflection, direct visualization or particle counting are used for detection. Capillary electrophoresis employing rectangular capillaries also allows for two-dimensional separations, the lateral separation being detected with a segmental detector 14.

Abstract: Apparatus and associated methods employed therewith for accurately providing a desired ("Aim") tone reproduction characteristic in an output image through a DDCP (direct digital color proofing) imaging chain (such as that implemented by a raster image processor (200), particularly a screening process (660) occurring therein, and a marking engine (130) and for significantly reducing the number of test proof images that need to be produced and measured to achieve this result. Specifically, "Benchmark" operating conditions and intrinsic performance (i.e. "Benchmark" entry point date) of the DDCP imaging chain thereat are first defined. Then, based upon differences (such as in screen ruling and solid area density) between a desired operating condition and an appropriate "Benchmark" condition, "Benchmark" values associated with the latter are adapted, through use of a pre-defined model and associated sensitivity coefficients that collectively predict the performance of the DDCP imaging chain, to determine corresponding "Adapted" values that accurately specify the intrinsic process tone reproduction characteristic of the imaging chain at the desired operating condition. Thereafter, in response to both "Aim" (400) and the "Adapted" values for the desired operating condition, a look-up table is fabricated to contain, for all possible input dot areas, the "Aim" dot gain modified by the inverse of this expected intrinsic process tone reproduction characteristic applied to the desired tone reproduction characteristic. Incoming dot area values (i.e. contone values) for a corresponding separation are then routed through this table, prior to screening and writing, in order to intentionally vary the tone reproduction value of each such value so that the resulting dots in the proof image will accurately exhibit the desired "Aim" tone reproduction characteristic substantially free from corruption due to the native tone reproduction characteristic of the imaging chain.

Abstract: A controller (12) that includes a number of switches is associated with a first appliance (10) that has a number of operating states. In at least one of the operating states of the first appliance, the controller responds to certain switch actuations by causing it to perform a task, but when it is in another operating state, the same switch actuations have no meaning insofar as the first appliance is concerned, so the controller responds by transmitting data signals to a second appliance (not shown) via a power line (18). In this manner, a single controller can be used to control a number of appliances when a particular switch actuation has no meaning in the context of controlling the associated appliance. For example, the keypad (12) of a telephone set (10) is used to select a particular television station. Control signals are sent by the telephone to the television (not shown) by spread spectrum data transmission over an AC power line (18). The data transmission format used is in accordance with the CEBUS® standard promulgated by the Electronic Industries Association.

Abstract: A DNA sequence encoding a potato leafroll virus coat protein having at least one internal translation initiation codon in a different reading frame than the native PLRV coat protein DNA sequence altered to a non-initiator codon is provided. Two translation initiation sites at the start of a 17kd open reading frame in a different reading frame than the native PLRV coat protein DNA sequence are preferably altered. A stronger stop codon is also provided in the modified PLRV DNA sequence. The modified DNA sequence having the internal translation initiation codons at the start of the 17kd open reading frame altered to non-initiator codons can be used in a gene to transform plants of the Solanaceae family to obtain transgenic plants resistant to PLRV. A synthetic modified potato leafroll virus DNA sequence is also provided which has the changes in the translation initiation sites and is further made to be more "plant-like". Multiple copies of the modified or synthetic modified PLRV coat protein DNA sequence driven by different promoters have also been transformed into potato with advantageous results. The modified potato leafroll virus DNA sequences of this invention are particularly useful in obtaining transgenic potato plants resistant to infection by potato leafroll virus.

Abstract: A copying machine as an example of electrophotographic printing machines is composed of a main body (1) which permits both black-and-white copying and full color copying, and a reverse and retransport unit (2) provided under the main body (1), for reversing and retransporting a sheet after being copied on one surface thereof to the main body (1). The main body (1) has a fixing means (200) including upper and lower fixing portions (200a, 200b) formed between three heat rollers (201-203). The lower fixing portion (200b) placed closer to the reverse and retransport unit (2) is associated with the black-and-white copying, and the upper fixing portion (200a) is associated with the full color copying. Upper and lower discharge transport paths (41,42) for discharging the sheet out of the device are provided so as to respectively extend from the upper and lower fixing portions (200a, 200b). Further, a retransport path (32) is provided so as to extend from the lower fixing portion (200b). Since the above three paths are provided without having any crossing point, the structure of the paths is simplified. Furthermore, when carrying out a black-and-white copying on one surface of the sheet and a color copying on the other surface, the black-and-white copying is carried out first, thereby eliminating the problem of the sheet being stuck in the device.
