Patent EP-0443989-A2 (EP)
Inventor: PASCUCCI LUIGI
IPC: G11C16/06
Filed: 1991-02-07
Abstract: A sense circuit for reading  EPROM  and  ROM  type memory cells employs a circuit for generating an offsetting current which is exempt of error during transients and which thus permits to achieve a reduced access time. On the other hand, the sense circuit maintains the intrinsic advantages of a current-offset sensing architecture which is represented by a substantially unlimited operating voltage range toward the maximum value  VCC     max   . The current generating circuit is driven by means of a supplementary row of cells which is decoded at every reading and which replicates, during transients, the behaviour of the row selected for the reading.

Abstract: A system for delivering ink to print heads (30a, 30b, 30c) in thermal ink jet printers includes a liquid compartment (40) with a gas space thereabove at sub-atmospheric pressure, a hydrophobic membrane (43) mounted between the liquid compartment and the surrounding environment for allowing ambient gases to bubble into the liquid while preventing liquid from flowing in the opposite direction through the membrane, at least one chamber (32a) that provides a reservoir of ink with a gas space thereabove at sub-atmospheric pressure, and a manifold (24) connecting the gas space in the liquid compartment with the gas space in the ink chamber. Thermal ink jet print heads (30a, 30b, 30c) are mounted in ink-flow communication with the ink chamber (32a, 32b, 32c) and are adapted for ejecting ink onto sheets to be printed. In operation, ink flows into the thermal ink jet print heads at a flow rate which is regulated by a generally constant back pressure. This novel pen body construction enables the hydrophobic membrane (43) to be completely isolated from the ink in the multiple ink reservoirs (32a, 32b, 32c) of the pen, with the advantage that ingredients and additives within the ink do not degrade the surface properties of the hydrophobic membrane material (43).

Abstract: An antenna element (1) has a linear antenna rod (1b) of predetermined length and a top load (1a) at the end of the rod (1b). The antenna element (1) takes a first position in which the rod is extracted out of a housing (8), and a second position in which the rod is retracted within the housing. There are provided two feed terminals (5, 6) along the rod (1b). The first feed terminal (5) is essentially matching the impedance of a node point in current distribution in the resonant antenna element, and feeds the antenna element at the end of the rod in the first position. The second feed terminal (5) is matching the impedance of an anti-node point in current distribution in the resonant antenna element, and feeds the antenna element at approximate center of the rod in the second position. A first feed terminal (5) might contact the rod in a second position, but it does not feed the same because of mismatching. Thus, the antenna system is always fed with matched condition whether it is extracted or retracted, through the automatic switching of feed terminals.

Abstract: Conditioned gas flows are applied at various critical locations in instruments and apparatus for testing and processing textile fibers, such as cotton. In the context of test instruments, a standard test zone environment (which becomes part of the test record) is effected by the introduction of controlled conditioned gas flows directly into a testing zone, including into testing instruments themselves. In the context of processing apparatus, direct control of machine performance parameters is effected by "controlling parameters", which are in turn effected by the application of conditioned gas flows. A plurality of "performance parameters", which may be in conflict with each other, may be controlled in accordance with a predetermined compromise control strategy, carried out by feedback or feedforward control systems implementing modern statistical control approaches.

IPC: H04N5/217

Abstract: Loss of brightness at the edges of an image is generally known as vignetting. Non-matching of stops in an optical system or, in particular in x-ray examination apparatus, variations in intensity of the x-ray beam and the combination of the image intensifier and the television camera tube give rise to vignetting. Compensating for vignetting is achieved by electronically multiplying the pixel-values of the vignetted image by a gain characteristic so as to obtain an unperturbed image. A gain characteristic pertaining to a particular vignetting effect is formed by a set of correction factors for all pixels. These correction factors are obtained from the image of an object having a spatially homogeneous brightness distribution. Various gain characteristics can be stored so that compensation for vignetting is sustained when the adjustments of the imaging system are varied. 
     In order to improve spatial resolution of the image formed on the output screen of an image intensifier in an x-ray examination apparatus a known method splits the image into two sub-images. Either of these images is subsequently detected by an opto-electronic sensor, e.g. a CCD-sensor. These sensors are mutually shifted such that the pixels of one sensor fall at the interstices of the other sensor. Upon recombination of both sub-images an image with improved spatial resolution results. Because of the use of a beam splitter the vignetting effects in either of the sub-images are inevitably different. The vignetting is decomposed in vignetting in a horizontal and in a vertical direction in the recombined image. Correction for vignetting is achieved by multiplying decomposition factors pertaining to horizontal and to vertical vignetting.

Abstract: A multilevel coded modulation scheme trellis encodes (in 1112) a portion of the input data and the resulting encoded stream is used to identify a particular one of a predetermined number of subsets of symbols of a predetermined signal constellation. The remaining input data is coded using a Reed-Solomon (RS) code (in 1114) whose output is used to select for transmission a particular symbol from the idendified subset. In applications in which phase hits or other channel phenomena may cause the received signal points to be phase-rotated versions of the signal points that were, transmitted, differential encoding (in 1107) is included in the overall coded modulation scheme. In different embodiments, the differential encoding/decoding and RS encoding/decoding are in different orders. In one such embodiment, overlapped multilevel codes are used to preserve the advantages afforded by taking a multilevel coding approach.
