Patent EP-0702482-A2 (EP)
Inventor: ESCHBACH REINER
IPC: B41J2/52
Filed: 1995-09-08
Abstract: A method and apparatus for quantizing pixels in an image formed by a plurality of pixels, each pixel constituting an image signal representing optical density of the image at a location therein, and having an original optical density value selected from one of a set of 'c' original optical density values that has a number of members larger than a desired output set of 'd' optical density values, through a process of error diffusion. For an input image so comprised, initially, an image signal is initially modified (12) in accordance with previously determined error (ε n,l ). Thereafter, during the quantization step of the process, the threshold signal (T n,l ) for quantization determination is dynamically adjusted (80-112) in accordance with previous output quantization determinations to selectively control likelihood of whether the next pixel will exceed the threshold. The threshold level is selectively modified on a pixel by pixel basis to increase or decrease the likelihood that the next pixel will be quantized to one state or another state. In addition to this control, however,the increase or decrease in the threshold level is based upon a regional input intensity. With the threshold signal set as described, the modified input signal is evaluated, and an output signal that is one of d levels is determined accordingly. Subsequent to quantization, the difference between the determined output signal and the modified input signal is evaluated and stored as error, to be dispersed for addition to a preselected group of unevaluated neighboring signals.

Abstract: An occlusive implant delivery assembly includes a rapid response decoupling or detachment mechanism that does not effect significant migration of the implant during release. The assembly includes an occlusive implant device, such as an embolic coil, a pusher or device to carry the implant to the selected location, and an expandable coupling-decoupling mechanism for releasing the implant at the selected site. The mechanical construction provides rapid release times. In addition, the releasing mechanism generally operates without exerting any significant force on the implant, thereby avoiding any significant displacement of the implant during release.

Abstract: A drop detector system and method are provided for a drop detector of the type including a drop chamber and an electro-optical sensor. The detector system detects drops passing through an optical sensing path between a detector and at least one light source. In response to the detection of a drop passing through the optical path, the detector produces an output signal. A capacitor is connected between the detector and an amplifier to block the DC component of the output signal. After amplification, the signal is passed through a low pass filter to further block signals caused by undesirable factors. The cutoff frequency of the low pass filter is controlled by a microprocessor that controls the pump that pumps liquid from the drop chamber. The detector and light source or sources are arranged to detect drops falling in the drop chamber at virtually any angle and in virtually any ambient light condition.

Abstract: A magnetic recording and/or reproducing head system particularly for use for writing and/or reading information on tracks in a magnetics-on-film (MOF) layer in the image area of photographic filmstrips, wherein the system provides for mounting of such magnetic heads on a suspension and translation system to move the magnetic heads from track to track of the MOF layer and longitudinally along a selected track. The filmstrip exhibits a lengthwise curvature of a predetermined sign and a cross-film curvature. The filmstrip is advanced to a stationary position in a curved transport path in the length dimension of the filmstrip, the curved transport path having a curvature radius of the same sign as the predetermined curvature sign of the filmstrip. The filmstrip edges are engaged in edge guides such that the transport path curvature and the edge guides negate cross-film curvature. The magnetic head is lengthwise translated along the selected track following the curvature radius on a head track selection assembly which includes a head track guide connected between first ends of a pair of positioning arms extending across the film edge guides for supporting the magnetic head for engagement and lengthwise translation with the filmstrip selected track by pivotal movement thereof. A head track motor drives the magnetic head along a head track selection assembly to a selected track position. The head track selection assembly includes a guide rod and a rotatable lead screw extending between free ends of the positioning arms and across the film transport path. Head mounting means for mounting the magnetic head in relation to the film transport path have a guide opening for engaging the guide rod for inhibiting rotation of the head mounting means about the lead screw on rotation of the lead screw and have a threaded bore for engaging the lead screw, whereby rotation of the lead screw effects translation of the head mounting means along the lead screw and guide rod and across the film transport path to a selected track.

Abstract: Purification of water contaminated with harmful substances, based on absorption and/or adsorption techniques, uses calcium ferrate hydrate to absorb and/or adsorb contaminants in the water. The calcium ferrate hydrate absorption agent (3) is prepared in situ during the purification process from iron hydroxide and calcium hydroxide and/or calcium oxide. The iron/calcium ratio is 0.35-7:1 and the reaction time required is 1-180 minutes. The reaction is carried out by adding the separate starting materials to the water (8) being purified, or by mixing the starting materials to form a powder or granulate which is then added to this water in powder, granule or aqueous suspension form. Calcium hydroxide is added as lime water. Residue from the iron removal step of a water treatment process is used as an iron hydroxide carrier. Water is added to this residue to form a flowable material before calcium (hydr)oxide is added to it. The pH of the water being purified is altered to 7-14 using a buffer.
