Patent EP-0438043-A2 (EP)
Inventor: KRUG JOHN A
IPC: A61F2/16
Filed: 1990-12-21
Abstract: An intraocular lens (10) is integrally machined from a blank of polymethylmethacrylate (PMMA) or copolymers thereof to provide an optic having a plurality of strong and resilient haptics. The lens is made from a PMMA material that is specially processed to provide greatly increased tensile strength and flexibility. The material surface is carefully polished to minimize irregularities. It is wrapped in a protective cover and heated to a range of between 35°C and 150°C. It is then clamped in a machine which multi-axially stretches the heated sheet, which is held in its stretched condition as it is cooled to room temperature. Multi-axis stretching under these conditions provides highly oriented polymer chains in the material which greatly increases tensile strength, flexibility and resiliency, thereby imparting these same qualities to the lens haptics (12,14).

Abstract: The invention describes a method of three-dimensional roll-stretch-bending in combination with a mandrel bending station and the corresponding apparatus for this purpose, the section to be bent first of all being clamped at both ends and subjected to a prestress and the section then being bent, at least one shaping roller being pressed against the section in the shaping region and adjusted in three dimensions. In order also to be able to bend closed or partially open sections, the mandrel bending station, having one or more mandrels around which the section to be bent is bent, is moved in the same direction as the shaping rollers, which are pressed against the mandrel bending station from the outside. <IMAGE>

Abstract: Disclosed is a rotor body for an electric machine having slots for windings and slot keys with wedges for retaining the windings in the slots. The slot keys contain elongated spring strips underlying an amortisseur, in turn, underlying the wedges in the slot keys. The spring strips bias the amortisseur and wedges radially outwardly. Thus, the wedges lie in sufficient, low-resistance, efficient electrical contact with the rotor body at start-up and during low rotor speeds to prevent arcing and localized heating along the interfaces of the rotor parts otherwise resultant from induced surface currents at start-up and low rotor speeds. At the rotor ends, the spring strips bias the amortisseur ends radially outwardly into efficient electrical contact with retaining rings at opposite ends of the rotor body. A tool is also provided having a main arm, a pair of pivotally mounted dogs for engagement in the slot key and straddling the external surface of the slot key, respectively, whereby the tool may be fixed in axial position along the slot key by pressure on the main arm. A second pivotal arm carries a wedge-engaging head whereby the lever is fixed in the slot and the second arm drives the wedge longitudinally into axial

Abstract: The invention relates to a video recorder for recording and reproducing text signals as accompanying information to helical-track audio recordings. Video recorders in which a high-quality recording of audio signals is carried out in the helical tracks of a video magnetic tape are already known. These audio signals may be sound information associated with a television broadcast or a pure audio recording, in which case the helical video tracks remain unused. According to the invention, the helical video tracks usually unused in the case of pure audio recording are used for recording accompanying information characterising the audio recording. <IMAGE>

Abstract: Collapsible cardboard box, in particular of corrugated cardboard, has, in its erected state, a rectangular bottom (5) and four side parts (1 to 4) which are joined to said bottom and are joined to one another via corner folds (11 to 14). In order to ensure that the base area of the collapsible cardboard box is just as small in the collapsed state as in the erected state, four crease folds (16 to 19) extend on all four side parts (1 to 4), each fold beginning at one corner fold (11 to 14) of the side part (1 to 4) near to the bottom (5) and extending obliquely up to the upper edge (34) of the side part (1 to 4). Provided additionally on at least one of the side parts (1 to 4) is at least one auxiliary fold (28) which begins at one corner fold (14) of the side part (1) near to the bottom (5) and extends obliquely up to the upper edge (34) of said side part (1).

Abstract: Disclosed is the invention offering an apparatus and a method for adjusting video display, with no need to determine precisely the positional relationship between an image input member and the video display area of a projector or monitor while the latter device is being adjusted for video display by detecting beam positions. The entire video display area is photographed by image input means. The video display area information thus obtained is represented by the coordinates, in a memory, of four points enclosing the area. The memory coordinates of first points to be obtained based on a reference image are calculated from the coordinates of these four points. The coordinates of the first points are compared with those of the second points determined with respect to the reference image. The result is used to operate a system controller for adjustment and control of video display.

Abstract: An adaptive feedforward equalizer (12) has switched (N - 1) tap-gain coefficients and a fixed tap-gain coefficient for the reference delay-line tap to operate on an incoming IF or baseband signal according to a first error signal (ε₁) representative of the difference between the input and output of a decision circuit (15). All tap-gain coefficients are active in the absence of an interference from an undesired source to cancel precursor distortion. The (N - 1) tap-gain coefficients are nullified when such an interference is detected to reduce its precursor-cancelling capability. A first feedback equalizer (17) operates on the output of the decision circuit according to the first error signal to cancel postcursor distortion. A second feedback equalizer (18) nonlinearly filters the output of the decision circuit according to a second error signal (ε₂) and generates an estimate of a desired component of the output of the feedforward equalizer. The outputs of the second feedback equalizer (18) and the feedforward equalizer (12) are combined to produce the second error signal, or an estimate of an undesired component of the output of the feedforward equalizer. In the presence of the interference, the desired component estimate (ε₂) is combined with the outputs of the feedforward equalizer (12) and the first feedback equalizer (17) to produce an equalized signal for coupling to the decision circuit.

Abstract: A high speed digital image preprocessing system for use in image recognition applications in which compressed image data is transmitted over a Small Computer System Interface (SCSI) for storage in a Multi-Purpose Buffer. The data may decompressed, byte-swapped, byte-flipped, or may be passed through the system unmodified as directed by the Host Computer. A Video Compression-Expansion Processor can handle a variety of data compression formats and receives data from the Multi-Purpose Buffer. Processed data which matches preprogrammed sets of window coordinates can be selectively cropped and stored in multiple First-In-First-Out (FIFO) buffers by Cropper Controller circuitry. The processed and cropped data is then sent to the Host Computer through a Micro-Channel Architecture (MCA) Interface Controller for further recognition processing by the Host Computer. A high data throughput rate is achieved by synchronizing data transfer among the components of the preprocessing system by use of the Multi-Purpose Buffer and a data window storage mechanism.
